[0002] In mortar production, raw material mixing, stirring and conveying can produce a large amount of dust, such as cement dust and sand dust, which deteriorates the air quality in the workshop. Long-term exposure to this environment increases the risk of respiratory diseases such as pneumoconiosis in workers, seriously endangering their health. At the same time, dust accumulation accelerates equipment wear and tear.

[0035] The working principle of the present embodiment is as follows:

[0036] The operator uses bolts to stably install the first electric motor 201 above the conical tank 1, installs the rotating shaft 202 outside the drive shaft of the first electric motor 201, and then installs the impeller 203 at the bottom of the rotating shaft 202, ensuring that the rotating shaft 202 and the impeller 203 are located inside the conical tank 1. The operator installs the drainage bend 102 on one side of the drainage shell 101, installs the electrostatic precipitator 3 in the stepped groove on one side of the drainage bend 102, ensures stable installation, installs the first collection shell 301 on the outside of the pollution discharge sleeve of the electrostatic precipitator 3 through interference fit structure, installs two positioning shells 4 at the bottom of the drainage bend 102, uses bolts to pass through the bolt installation holes in the corners of the positioning shells 4 to stably assemble the two positioning shells 4, installs the filter screen 5 between the inclined positioning groove at the bottom of the positioning shell 4 and the inclined installation hole above, installs the second electric motor 601 in the stable groove inside the stable frame 9, installs the positioning frame 602 above the drive shaft of the second electric motor 601, installs the positioning pin 7 through the edge installation hole of the positioning frame 602, and installs the supporting spring and the snap spring outside; the operator installs the pressure sensor 8 inside the installation hole, passes the second collection shell 603 through the positioning frame 602, and positions the positioning ring above the second collection shell 603 with the positioning frame 602.

[0037] The operator turns on the power supply of the first electric motor 201 and starts the first electric motor 201. The first electric motor 201 drives the rotating shaft 202 and the impeller 203 to rotate at high speed, forming a cyclone inside the conical tank 1. The sand is poured into the conical tank 1 through the sand pouring sleeve above the drainage shell 101. Under the action of the cyclone, the sand does rotational flow movement in the conical tank 1. The heavier sand particles gradually settle at the bottom and are discharged from the sand outlet.

[0038] The dust generated during the sand rotational flow process is discharged through the dust discharge hole between the conical tank 1, the drainage shell 101 and the drainage bend 102. The discharged dust gas flows through the electrostatic precipitator 3. Under the action of static electricity, the dust particles are adsorbed on the surface of the electrostatic precipitator 3. The purified air is discharged through the flow hole. With the accumulation of dust on the surface of the electrostatic precipitator 3, part of the dust will fall off and fall into the first collection shell 301 through the pollution discharge sleeve.

[0039] The airflow generated by the centrifugal mechanism 2 is transported to the positioning shell 4 through the drainage pipe. The dust in the airflow is further filtered when passing through the inclined filter screen 5. The inclined filter screen 5 prolongs the contact path of the dust and the filter screen, improving the filtering effect. The filtered dust falls to the bottom of the positioning shell 4 and enters the second collection shell 603 through the vertical pollution discharge sleeve.

[0040] When the dust in the second collecting shell 603 accumulates to a certain weight, the second collecting shell 603 moves downward, compresses the supporting spring, and presses the pressure sensor 8 above the second collecting shell 603, the pressure sensor 8 transmits a pressure signal to the control module, and after the control module receives the signal, the second electric motor 601 is driven to work, so that the second collecting shell 603 is switched to ensure continuous dust collection;

[0041] Stop feeding the sand sleeve, wait for the sand in the conical tank 1 to be discharged, turn off the first electric motor 201, wait for a period of time, let the dust on the electrostatic adsorber 3 and the filter screen 5 fall into the collecting device, disassemble the first collecting shell 301, clean the collected dust, and then reinstall it, and clean the dust in the second collecting shell 603.

[0042] In this paper, the following points need attention:

[0043] 1. The drawings of the embodiments of the present disclosure only relate to the structures involved in the embodiments of the present disclosure, and other structures can refer to the usual design.

[0044] 2. In the case of no conflict, the embodiments of the present disclosure and the features in the embodiments can be combined to obtain new embodiments.

[0045] The above is only a specific embodiment of the present disclosure, but the protection scope of the present disclosure is not limited to this, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present disclosure, which should be covered within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be subject to the protection scope of the claims.
