DETAILED DESCRIPTION

[0025] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0026] like Figures 1 to 4 As shown, and refer to Figure 1 In the orientation shown in , an embodiment of the dust reduction equipment for chemical production safety of the present invention comprises a mobile frame 90, a dust hood 20, an air duct 10, a dust removal motor 110, a guide pipe 120, a dust collection bin 70, a dust reduction assembly and a spray assembly. The dust hood 20 is arranged on the mobile frame 90, the air duct 10 is installed on the upper end of the dust hood 20, two groups of spray assemblies are arranged symmetrically on the dust hood 20, and two groups of dust reduction assemblies are arranged symmetrically on the dust hood 20. The mobile frame 90 enables the dust reduction equipment for chemical production safety to be easily moved to different working positions, which is convenient for the rapid conversion of the dust reduction equipment for chemical production safety between different working areas.

[0027] like Figure 2As shown, the dust hood 20 includes a first straight section 210, a horn section 220 and a second straight section 230 connected in sequence from top to bottom, and the horn section 220 gradually expands from the first straight section 210 to the second straight section 230. A middle plate 240 is provided in the dust hood 20 to separate the two groups of dust suppression components. The middle plate 240 is fixed to the inner wall of the first straight section 210 and extends to the lower end of the horn section 220. The dust collecting bin 70 is fixed to the lower end of the middle plate 240 and is provided in the second straight section 230.

[0028] like Figure 1 and Figure 2 As shown, a plurality of heat exchange fins are equidistantly installed in a circular shape on the inner wall of the air duct 10, and a sealing can is installed together at one end of the plurality of heat exchange fins away from the inner wall of the air duct 10. A dust removal motor 110 is installed in the sealed can. The dust removal motor 110 is a double-axis motor. Both shafts of the dust removal motor 110 extend outside the sealed can and are installed with negative pressure fan blades. A guide tube 120 is provided at the upper end of the air duct 10. Thus, the heat generated by the dust removal motor 110 during operation is exchanged with the air flow through the heat exchange fins, so that the temperature of the air flow rises and the temperature of the dust removal motor 110 is reduced, the dust removal motor 110 is cooled, and the hot air flow is discharged through the guide tube 120 for recycling.

[0029] like Figure 1 and Figure 2 As shown, each spray assembly includes a water tank 910 and a spray head 920, and the spray head 920 is disposed on the water tank 910. One end of the guide pipe 120 away from the air duct 10 passes through the side wall of the first straight tube section 210 and communicates with the lower end of the water tank 910.

[0030] like Figures 1 to 4 As shown, each dust reduction component includes a filter plate 40, a cover plate 30, a cleaning strip 50, a drying device, a baffle 710, a first motor 410, a first linear drive member 320, a second linear drive member 510, a threaded rod 250, a flushing head 80, absorbent cotton 820 and a second motor 830.

[0031] like Figures 1 to 4 As shown, the filter plate 40 is rotatably mounted on the inner wall of the first straight cylinder section 210 through a rotating shaft 430, the first motor 410 is mounted outside the dust cover 20, and the output end of the first motor 410 is connected to the filter plate 40 to drive the filter plate 40 to rotate. The upper surface of the filter plate 40 is provided with a mounting groove 420 extending left and right, one end of the mounting groove 420 close to the inner wall of the dust cover 20 is connected to the outside, and the end of the mounting groove 420 away from the inner wall of the dust cover 20 has a stopper, and the lower surface of the cover plate 30 is provided with a mounting piece that slidably cooperates with the mounting groove 420, and the cross section of the mounting piece is an inverted T-shape, so that the cover plate 30 can be moved left and right to be assembled on the upper surface of the filter plate 40, and when the cover plate 30 moves left and right relative to the upper surface of the filter plate 40, the filter plate 40 can be controlled to switch between the working state and the rest state.

[0032] like Figure 1 and Figure 2 As shown, the first linear drive member 320 is installed outside the dust cover 20, and the output end of the first linear drive member 320 is connected to the transmission member 330 to drive the transmission member 330 to move left and right, and the transmission member 330 is magnetically connected to the cover plate 30. Therefore, the transmission member 330 is driven to move left and right by the first linear drive member 320, so that the transmission member 330 drives the cover plate 30 to move left and right.

[0033] like Figure 1 and Figure 2 As shown, the cleaning strip 50 is assembled on the first straight section 210 and is located on the lower surface of the filter plate 40 to clean the filter plate 40 when the filter plate 40 is switched to the rest state. The cleaning strip 50 in the embodiment is a cleaning brush, and the bristles of the cleaning brush are made of rigid materials such as plastic and metal to scrub the dust attached to the lower surface of the filter plate 40. The baffle 710 is assembled on the second straight section 230 and moves synchronously with the cleaning strip 50 to cover the upper opening of the dust bin 70. When the baffle 710 moves left and right relative to the dust bin 70, the side wall of the dust bin 70 can scrape the dust on the upper surface of the baffle 710 into the dust bin 70. The second linear drive member 510 is installed outside the dust collecting cover 20. The output end of the second linear drive member 510 is connected to the moving plate 520 to drive the moving plate 520 to move left and right. The cleaning strip 50 and the baffle 710 are fixedly connected to the moving plate 520 respectively. Thus, the second linear driving member 510 drives the moving plate 520 to move left and right, so that the moving plate 520 drives the cleaning bar 50 and the baffle 710 to move left and right synchronously.

[0034] The first linear driving member 320 and the second linear driving member 510 are respectively any one of an electric push rod, a hydraulic cylinder and a pneumatic cylinder.

[0035] like Figures 1 to 3As shown, the drying device is arranged below the cleaning strip 50, and the drying device includes a drying member 60 arranged on the side wall of the first straight tube section 210 and a partition 610 which is assembled on the inner wall of the first straight tube section 210 and moves up and down. The guide tube 120 is stacked and spirally embedded in the drying member 60 so that the drying member 60 absorbs heat and the temperature rises. The drying member 60 is used to dry the filter plate 40 when the filter plate 40 rotates downward to a vertical state. The partition 610 is used to isolate the drying member 60 from the outside to play a role in heat preservation. The threaded rod 250 is rotatably installed on the inner wall of the first straight tube section 210, the threaded rod 250 is fixedly connected to the friction wheel 1 251, the rotating shaft 430 is fixedly connected to the friction wheel 2 431, the friction wheel 2 431 contacts the friction wheel 1 251, and the partition 610 is provided with a threaded hole threadedly connected to the threaded rod 250. Therefore, when the filter plate 40 rotates, the threaded rod 250 is driven to rotate through the friction transmission of the two friction wheels, and then the threaded rod 250 and the partition 610 are spirally transmitted, so that the partition 610 moves up and down. It is supplemented here that when the filter plate 40 rotates upward from a horizontal state to a vertical state, the partition 610 is restricted by the rotating shaft 430 of the filter plate 40 and cannot move upward. At this time, the two friction wheels slip.

[0036] like Figure 2 and Figure 4 As shown, the flushing head 80 is arranged at the upper end of the inner wall of the first straight cylindrical section 210, and the flushing head 80 is connected to the water tank 910 through the connecting pipe 810. The filter plate 40 includes a first plate body 440 and a second plate body 450 which are parallel to each other. The first plate body 440 is distributed above the second plate body 450 in the air. When the filter plate 40 is rotated upward to a vertical state, the flushing head 80 is opposite to the gap between the first plate body 440 and the second plate body 450 to flush the filter plate 40, thereby avoiding impurities adhering to the filter plate 40 that cannot be thoroughly cleaned only by moving the cleaning strip 50 left and right, thereby improving the cleaning effect.

[0037] like Figure 1 and Figure 2 As shown, the absorbent cotton 820 is arranged at the upper end opening of the first straight cylindrical section 210, and the second motor 830 is installed outside the dust cover 20. The output end of the second motor 830 is connected to the absorbent cotton 820 to drive the absorbent cotton 820 to rotate. The absorbent cotton 820 is used to absorb water and wipe the filter plate 40 after washing to prevent the filter plate 40 from being excessively wet.

[0038] The working process of the embodiment of the chemical production safety dust reduction equipment of the present invention comprises the following steps:

[0039] The first step is to start the dust removal motor 110, the negative pressure fan blades rotate, and the nozzle 920 sprays water vapor to moisten the air and settle the dust in the air to the ground. The dust hood 20 sucks the dust on the ground, and the two cover plates 30 move outward respectively, so that the two filter plates 40 are in working condition, and the dust-containing gas is filtered. The filtered dust adheres to the lower surface of the filter plate 40, and the filtered air flow exchanges heat with the heat exchange plate to dissipate the heat of the dust removal motor 110. The hot air flow is discharged through the guide pipe 120. After the guide pipe 120 transfers the heat to the drying part 60, the remaining heat flows with the air flow to the water tank 910, so that the air flow temperature drops and the water temperature increases to increase the evaporation capacity.

[0040] In the second step, after working for a period of time, one of the first linear driving members 320 is started, and the cover plate 30 is controlled to move inward to the upper surface of the corresponding filter plate 40 to block the airflow from passing through the filter plate 40, so that the filter plate 40 enters a rest state, and the second linear driving member 510 on the same side is started, and the cleaning bar 50 and the baffle 710 are controlled to move outward, and the cleaning bar 50 cleans the lower surface of the filter plate 40, and the dust falling from the cleaning falls on the upper surface of the baffle 710 on the dust collecting bin 70, and the dust on the upper surface of the baffle 710 is pushed into the dust collecting bin 70 through the side wall of the dust collecting bin 70. After the filter plate 40 on this side is cleaned and the cover plate 30, the cleaning bar 50 and the baffle 710 are reset, the filter plate 40 on the other side is cleaned.

[0041] The third step is to turn off the dust removal motor 110, and simultaneously thoroughly clean the filter plates 40 on the left and right sides, start the second linear drive member 510, control the cleaning strip 50 and the baffle 710 to move outward, start the first motor 410, control the filter plate 40 to rotate upward to a vertical state, and the flushing head 80 flushes the filter plate 40, start the second motor 830, control the absorbent cotton 820 to rotate downward to a vertical state, and wipe the filter plate 40 with water, start the first motor 410, control the filter plate 40 to rotate downward to a vertical state, and the cover plate 30 is disengaged from the transmission member 330 and rotates downward synchronously with the filter plate 40. The rotation of the filter plate 40 drives the partition 610 to move downward so that the filter plate 40 is located between the drying member 60 and the cover plate 30, and the drying member 60 dries the filter plate 40, and the cover plate 30 prevents heat loss.

[0042] In this way, the chemical production safety dust reduction equipment of the present invention sets two groups of left-right symmetrical dust reduction components on the dust collecting hood 20. When the dust removal motor 110 is working normally, the corresponding filter plate 40 is controlled to switch between the working state and the rest state by the left-right movement of each cover plate 30; when the filter plate 40 enters the working state, the dust-containing gas is filtered, and the filtered dust adheres to the lower surface of the filter plate 40; when the filter plate 40 enters the rest state, the lower surface of the filter plate 40 is cleaned by the left-right movement of the cleaning bar 50, and the cleaned fallen dust falls on the upper surface of the baffle 710 on the dust collecting bin 70, and the dust on the upper surface of the baffle 710 is pushed into the dust collecting bin 70 by the side wall of the dust collecting bin 70. When the baffle 710 is reset with the cleaning bar 50, it can cover the upper end opening of the dust collecting bin 70 to prevent the dust therein from being dispersed; the two filter plates 40 can work at the same time for a period of time and then be cleaned alternately to ensure that the filter plate 40 always maintains the best working state, reduce maintenance costs, and improve the dust removal efficiency of the dust reduction equipment. When the dust removal motor 110 stops working, the filter plate 40 is dried by the drying element 60 to remove moisture on the filter plate 40 , prevent the filter plate 40 from mold and corrosion, extend the service life of the filter plate 40 , and improve the filtering efficiency of the filter plate 40 .
