Description

Technical Field

[0001] The present invention belongs to the technical field of dust removal equipment, and particularly relates to a dust removal device for processing hollow plastic building templates. Background Art

[0002] Building templates are auxiliary materials widely used in the construction industry. They are set up according to construction requirements, and then concrete is poured into the templates. They have special properties such as acid resistance, alkali resistance, and corrosion resistance. Hollow plastic building templates adopt a hollow structure. The high turnover and stability of the products reduce production costs and improve operation efficiency for the construction industry, and are widely used in the market. During the forming process of plastic building templates, a large amount of tail gas is generated. Existing equipment cannot effectively remove dust from the tail gas. The dust particles in the gas are not easy to clean, and direct discharge to the outside is likely to cause air pollution.

[0003] For this reason, a Chinese patent with the patent number CN212632223U discloses a tail gas treatment device for a plastic building template forming machine, including a connecting pipe and a treatment box. The air outlet at the top of the treatment box is communicated with one end of a second fan through a conveying pipe. The other end of the second fan is communicated with the air inlet of a low-temperature plasma treatment device through a pipeline. The air outlet of the low-temperature plasma treatment device is communicated with the air inlet of a buffer deodorization box through a pipeline. The air outlet of the buffer deodorization box is communicated with one end of a third fan through a pipeline. The other end of the third fan is communicated with one end of an exhaust pipe; by discharging the tail gas into the treatment box for dust removal and filtration treatment, a partition plate is arranged in the treatment box. A number of ventilation holes are evenly distributed on the partition plate, and the bottom of the partition plate is a dust removal area, and the top of the partition plate is a filtration area. A first filter plate and a second filter plate are sequentially arranged from bottom to top in the filtration area. After being treated by the low-temperature plasma treatment device and deodorized by the buffer deodorization box, an activated carbon adsorption plate is arranged in the buffer deodorization box to ensure the safety of tail gas discharge.

[0004] However, in the above device, the dust particles in the tail gas are extremely easy to block the first filter plate, the second filter plate, and the activated carbon adsorption plate. When cleaning, the first filter plate, the second filter plate, and the activated carbon adsorption plate need to be disassembled, which is time-consuming and laborious, consumes working time, is not conducive to timely automatic cleaning, affects the continuity of work, and then affects the dust removal work efficiency.

[0034] With the above solution, when cleaning the first inclined filter plate 11 and the second inclined filter plate 12, at this time, the non-toothed part of the semi-toothed disc 7 corresponds to the second rack 602, and the lifting toothed plate 6 remains stationary. When cleaning the activated carbon filter plate 10, the semi-toothed disc 7 rotates reversely so that its toothed part meshes with the second rack 602, and then the second rack 602 drives the lifting toothed plate 6 to move upward. The toothed part of the semi-toothed disc 7 rotates forward and backward at the second rack 602, which can drive the lifting toothed plate 6 to move upward and then reset downward, realizing the lifting operation.

[0036] With the above solution, when the lifting toothed plate 6 moves up and down, it drives the first rack 601 to move synchronously. The first rack 601 drives the toothed ring 502 to rotate, and then drives the lead screw 5 to rotate, so that the sliding block 501 drives the air delivery pipe 3 and the water delivery pipe 4 to move along the corresponding lead screws 5, thereby driving the blowing cleaning part and the dust reduction cleaning part to move left and right inside the dust removal box 2, realizing the back-and-forth blowing cleaning operation and the back-and-forth spraying dust reduction operation.

Elastic hoses 503 are fixedly connected to the middle parts of the air delivery pipe 3 and the water delivery pipe 4, and the ends of the elastic hoses 503 are fixedly connected with connecting pipes 504. The connecting pipes 504 are fixed to the outer wall of the dust removal box 2. A hot air blower 302 and a water pump 402 are fixedly installed on the outer wall of the dust removal box 2.

[0038] With the above solution, when cleaning the activated carbon filter plate 10, start the hot air blower 302, and use the air duct 3 and the hot air nozzle 301 to blow the activated carbon filter plate 10 back and forth with hot air. Under the action of the hot air, the pollutants adsorbed on the activated carbon filter plate 10 can volatilize and desorb, and at the same time, the dust on it can be blown off, improving the recycling rate of the activated carbon filter plate 10, realizing automatic cleaning, being flexible and convenient to use. When performing the dust reduction operation, start the water pump 402, and use the water pipe 4 and the atomizing nozzle 401 to perform dust reduction treatment on the gas, separating the solid dust particles in the air, and facilitating the back-and-forth movement of the air duct 3 and the water pipe 4 through the elastic hose 503.

[0039] Specifically, the bottom of the lifting toothed plate 6 is fixedly connected to the side wall of the support frame 1 through a support spring 603. The dust removal box 2 is fixedly connected to the top of the support frame 1.

[0042] With the above solution, when the vibration cleaning member drives the second inclined filter plate 12 to vibrate up and down, when the second inclined filter plate 12 moves downward, it will push the push rod 9, causing the push rod 9 to drive the scraping ring 903 to slide along the inner wall of the intake pipe 201. When the second inclined filter plate 12 resets upward, under the action of the telescopic spring 901, it drives the push rod 9 to reset, and then drives the scraping ring 903 to slide and reset, so as to facilitate the back-and-forth scraping and cleaning operation of some dust particles attached to the inner part of the intake pipe 201. Automatic cleaning saves time and effort, effectively avoiding the situation that dust particles accumulate in the intake pipe 201 and cause blockage, thereby further improving the dust removal efficiency.

[0043] The working principle of the present invention: During use, connect the air inlet pipe 201 to the exhaust gas outlet of the hollow plastic building formwork molding machine, introduce the exhaust gas into the bottom of the dust removal box 2, start the water pump 402 and the motor 701, and use the water delivery pipe 4 and the atomizing nozzle 401 to perform dust reduction treatment on the gas, separating the solid dust particles in the exhaust gas. Moreover, the motor 701 drives the semi-toothed disc 7 to rotate, and the tooth part of the semi-toothed disc 7 rotates along the second rack 602 of the lifting toothed plate 6, causing the second rack 602 to drive the lifting toothed plate 6 and the first rack 601 to perform lifting and sliding. The first rack 601 drives the toothed ring 502 and the lead screw 5 to rotate, and then drives the water delivery pipe 4 to move back and forth, realizing the spraying and dust reduction work of moving back and forth. The exhaust gas passes through the second inclined filter plate 12, the first inclined filter plate 11 and the activated carbon filter plate 10, realizing that the dust particles are filtered, the harmful substances are adsorbed and the peculiar smell is removed. Finally, the clean air is discharged through the air outlet pipe 202.

[0044] When it is necessary to clean the activated carbon filter plate 10, start the hot air blower 302, and use the air delivery pipe 3 and the hot air nozzle 301 to perform back-and-forth hot air blowing and sweeping on the activated carbon filter plate 10. Under the action of the hot air, the pollutants adsorbed on the activated carbon filter plate 10 can volatilize and desorb, and at the same time, the dust on it can also be blown off, improving the recycling rate of the activated carbon filter plate 10 and realizing automatic cleaning, which is flexible and convenient to use.

[0045] When cleaning the first inclined filter plate 11 and the second inclined filter plate 12, the semi-toothed disc 7 rotates, driving the gear 802 to rotate along the tooth part of the semi-toothed disc 7, and then driving the cam 8 on the rotating rod 801 to rotate, so that the convex part of the cam 8 slides over the first inclined filter plate 11 and the second inclined filter plate 12 in turn and resets, and then drives the first inclined filter plate 11 and the second inclined filter plate 12 to vibrate up and down, facilitating the vibration of the blocked particles and their rapid guiding and dropping along the inclined plane, and then facilitating the rapid discharge of the dust particles, improving the dust removal and filtering effect.

[0046] The scraping and cleaning part not only facilitates the stable support of the bottom of the second inclined filter plate 12, but also can cooperate with the vibrating second inclined filter plate 12 up and down, so that the push rod 9 drives the scraping ring 903 to perform back-and-forth scraping and cleaning along the air inlet pipe 201, effectively avoiding the situation that the dust particles accumulate in the air inlet pipe 201 and cause blockage, thereby further improving the dust removal efficiency.
