The invention discloses a ceramic dust removal device, which comprises a tank body, a filtering mechanism and a pneumatic spraying mechanism. The filtering mechanism is arranged in the inner cavity of the tank, and divides the inner cavity of the tank into a first cavity and a second cavity; the pneumatic spray device includes a pneumatic component and a spray component. Wherein, the pneumatic component includes a pneumatic port, an elastic membrane, an elastic piece, and a conducting rod; the spray component includes a water inlet, a spray pipe, and a quick-cut valve. In the ceramic dust removal device of this structure, the filter mechanism is sealed with the inner wall of the tank, there is no gap, and the dust removal efficiency is high; through the pneumatic component linkage with the spray component, the dust or glaze on the filter mechanism is automatically removed to achieve continuous operation and equipment utilization. High production capacity; and according to the deposition degree of dust or glaze on the filter mechanism and the adsorption degree of the filter mechanism to dust or glaze, the opening of the quick-cut valve and the spraying timing are controlled in real time, saving spraying liquid and reducing Dust removal costs.

The invention relates to an underground coal mining device, which comprises a coal shearer, a rocker arm of the coal shearer is fixedly connected to a dust removal hood, and the dust removal hood comprises four side surfaces: an upper side, a lower side, a left side and a right side; The upper dust removal board is provided with atomizing nozzles, the lower side is provided with a lower baffle, the lower baffle is provided with a lower atomizing nozzle, the left and right side panels are provided with left and right baffles, and the inner sides of the left and right baffles are provided with dust removal ports. The outer side of the baffle is slidingly connected to the left and right dust removal boards, and the left and right dust removal boards are equipped with atomizing nozzles. The PLC control system receives the monitoring signals of the temperature sensor, gas concentration sensor, pressure sensor and dust concentration sensor, and compares them with the set value to control the LED light. With changing the display state to transmit the current state of each signal, the invention combines water spraying and dust removal with adsorption and dust removal, and the dust removal effect is good. At the same time, the safety value and threshold value are set, and the direction with hidden dangers can be checked in time to better solve the mine safety problem. , to improve the safety of underground coal mining.

The invention relates to a yeast production and preparation process, which uses a yeast production and preparation device, the yeast production and preparation device includes a supernatant mechanism and a lower cleaning mechanism, and the lower end of the supernatant mechanism is installed on the existing working On the ground, the lower right side of the supernatant mechanism is provided with a lower clearing mechanism, and the lower end of the lower clearing mechanism is installed on the existing working ground. The cooperation with the lower clearing mechanism can carry out double filtration treatment on the milk, thereby greatly improving the filtration effect of the yeast emulsion to reduce the impact on the subsequent use and reprocessing of the yeast, and at the same time, the lower clearing mechanism can simultaneously play a role in synchronous feeding At the same time, the emulsion and the supernatant mechanism can be in a state of motion, which can increase the floating amount of light impurities on the liquid surface, thereby improving the effect of filtering and removing light impurities.

The invention discloses a sorting device of brake pad steel backings. The sorting device comprises a supporting platform, a rotary supporting drive mechanism, a rotary barrel, a steel backing chute and an arc steel backing protection plate. The rotary supporting drive mechanism comprises rotary supporting legs and a rotary drive motor. A strip groove perpendicular to the side wall of the rotary barrel is arranged on the inner side wall of the rotary barrel. The front end and the rear end of the rotary barrel are erected on the supporting platform through the two correspondingly rotary supporting legs. The steel backing chute is obliquely sleeved in the rotary barrel. A filter opening is arranged at the rear end of the steel backing chute. The arc steel backing protection plate is arrangedon one side of the position over the front end of the steel backing chute. The strip groove drives the steel backings into the steel backing chute through rotation of the rotary barrel. The steel backings are filtered through the filter opening in the steel backing chute, the steel backings meeting the ranking requirement further pass through the steel backing chute to enter the next machining procedure of the steel backings, and therefore automatic orientated ranking of the steel backings can be achieved, and the machining efficiency of the steel backings can be improved easily.

The invention discloses an improved cross flow filtering device and a filtering assembly used for the same to optimize the mounting sealing performance of the filtering assembly in the cross flow filtering device. The cross flow filtering device comprises a shell and a filtering assembly positioned in the shell, wherein an annular shoulder positioned above an upper pore plate in the shell is arranged on the peripheral wall of an upper end connector of the filtering assembly; an annular sealing element is arranged between a step surface of the bottom of the annular shoulder and the top surface of the upper pore plate; and a pressing mechanism, which presses a step surface at the top of the annular shoulder downwards to ensure that the step surface of the bottom of the annular shoulder squeezes the annular sealing element downwards, is arranged at the top surface of the upper pore plate. The mounting manner of the filtering assembly ensures axial positioning of the filtering assembly, and by combining with the annular sealing component which is arranged between the step surface of the bottom of the annular shoulder and the top surface of the upper pore plate and is deformed by virtue of axial extrusion, the sealing reliability is greatly improved.
