Abstract: An evaluation device (20) evaluates the operating conditions of a briquetting machine (10). The evaluation device (20) includes an evaluation information acquisition unit (220) and an evaluation data generation unit (230). The evaluation information acquisition unit (220) acquires a plurality of pieces of evaluation information indicating the evaluation results of a plurality of briquettes manufactured under the same manufacturing conditions by the briquetting machine (10). The evaluation data generation unit (230) generates evaluation data that is data obtained by comparing a plurality of pieces of evaluation information with each other.

Abstract: A conveyor apparatus includes an endless conveyor belt wound around outgoing path side guide pulleys in turn along a helical conveyance path in a bent state where the belt is folded in two in a width direction such that an upper edge portion thereof is supported by the outgoing path side guide pulleys, and wound around returning path side guide pulleys in turn along the helical conveyance path in the bent state where the belt is folded in two in the width direction such that the upper edge portion is supported by the returning path side guide pulleys, and folded back at each turning positions of a horizontal conveyance unit located at an upper side and a horizontal conveyance unit located at a lower side of the support frame and being in an expanded state where the belt expanded in the width direction in a vicinity of the turning position.

Abstract: The quality of the briquettes granulated by a briquetting machine is improved. A briquetting machine control device samples the briquette that have been produced to measure an apparent density and a crush strength of the sampled briquette (step S10), and controls each operation set value adjusting unit (4, 6, 7) of the briquetting machine so that the actual measurement values come closer to predefined briquette quality target values (step S20 to step S60).

Abstract: A briquette inspection device and a briquette inspection method are capable of measuring at least a volume and a crush strength of an identical briquette sample. The briquette inspection device 10 is provided with: a volume measuring unit 2 for measuring the volume of the briquette sample B by laser scanning; and a crush strength measuring unit 3 for measuring the crush strength of the briquette sample B by pressing down and crushing the briquette sample B after the volume measuring unit measures the volume of the briquette sample.

Abstract: There is provided a stator seal structure in a uniaxial eccentric screw pump by which the abrasion resistance of sealing mechanisms is improved and the pumped fluid can be prevented from stagnating in the sealing mechanisms. The stator seal structure is provided with a pair of sealing mechanisms for sealing between a housing and an intake side end portion, and between the housing and a discharge side end portion of the stator. The pair of sealing mechanisms is provided with ring-shaped secured rings respectively secured to the housing. The secured rings are respectively attached with elastic bodies for ensuring contact pressures between the sliding seal surface of the stator and the sliding seal surface of the secured rings with the elastic forces of the elastic bodies and for sealing between the secured rings and the housing.

Abstract: Disclosed is a uniaxial eccentric screw pump that can prevent the life of a bearing sliding portion from decreasing due to a thrust load applied from a high pressure side to a low pressure side. An external thread-like motor directly coupled with a driving shaft is rotated and eccentrically moved with respect to the axis of a stator to deliver a fluid from an intake side to a discharge side. The pump is provided at an end of the discharge side of the motor and extends toward the discharge side in the axial direction of the stator. The uniaxial eccentric screw pump includes an annular small-diameter portion and a seal member. The seal member is in sliding contact with the outer surface of the small-diameter portion and seals the end of a sliding portion between a self-lubricating bearing on the discharge side and the stator.

Abstract: An object of the present invention is to provide an electric dust collector with its dust collecting performance being improved for collecting dust-like particles contained in a gas, whereas the increase in size thereof is being suppressed. An electric dust collector distributes a gas that has flown into a distribution chamber to a plurality of charging flow paths in a casing thereof, causes the distributed gas to flow from the insides of the charging flow paths into internal flow paths through mesh filters that are formed as parts of the dust collecting electrodes and that have a large surface areas per unit volume. Then, the gas is discharged to a central chamber through internal outlets. Subsequently, the flow of the gas is controlled to be discharged to the outside through a gas outlet.

An electric dust collector 10 distributes a gas G that has flown into a distribution chamber 90 to a plurality of charging flow paths 58 in a casing 12 thereof, causes the distributed gas to flow from insides of the charging flow paths 58 into internal flow paths 28 through mesh filters 30 that are formed as parts of the dust collecting electrodes 16 and that have large surface areas per unit volume. Then, the gas G is discharged to a central chamber 33 through internal outlets 32. Subsequently, the flow of the gas G is controlled to be discharged to the outside through a gas outlet 24.
