Description

Technical Field

[0001] The utility model relates to the technical field of solid waste, in particular to a solid waste dust collection device. Background Art

[0002] In industrial production workshops, especially in the links involving dust generation, dust emissions are extremely high. These dusts mainly include metal dust, mineral dust, organic dust, etc. Long-term inhalation of such dusts poses a serious threat to human health. When the accumulation of dust in the lungs reaches a certain level, its impact on human health will gradually become apparent, causing respiratory diseases at the mildest and malignant diseases such as lung cancer at the worst.

[0003] At present, dust collectors achieve dust removal effects by filtering air in multiple layers. During long-term operation, a large amount of dust will accumulate on the surface of the filter bag. In order to keep the bag clean, the equipment is equipped with a back-blowing mechanism to blow off the dust attached to the bag and achieve automatic cleaning.

[0004] The prior art proposes a Chinese patent with publication number CN 219879424U to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: it includes a secondary separation and collection device connected to one side of the dust removal bin, the secondary separation and collection device includes an exhaust pipe fixedly arranged on the side wall of the dust removal bin, the exhaust pipe is fixedly connected to the upper and lower staggered baffles, the bottom of the exhaust pipe is fixedly connected to the dust funnel, when the gas carrying dust passes through the exhaust pipe, the air meets the baffle, effectively reducing the circulation speed of the gas, due to the gravity of the dust, the dust will fall, and the dust will fall into the dust collection device through the dust funnel, effectively removing a large amount of dust, solving the problem that when performing backblowing operation, the gas will be discharged to the outside from the air inlet, and the impurities originally filtered will be mixed in the air and discharged together, forming secondary pollution, but the dust treatment and collection effect is poor. Utility Model Content

[0005] The purpose of the utility model is to provide a solid waste dust collection device to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A solid waste dust collection device comprises an air intake box and a dust suppression box; an air intake port is provided on one side of the air intake box, a primary screener is provided on one side of the air intake port, and the primary screener can preliminarily settle the gas input from the air intake port; a water tank is provided below the primary screener; a dust suppressor is fixedly provided on the dust suppression box, and a plurality of channels are provided on the dust suppressor; a water storage pipe is provided on the dust suppressor, and the water storage pipe is communicated with the water tank; a plurality of nozzles are provided on the inner wall of the channel, and a nozzle is provided on the nozzle, and the nozzle is communicated with the water storage pipe, and a collection box is fixedly provided on the side of the dust suppressor away from the air intake box.

[0008] The gas containing dust enters the air intake box through the air inlet; after entering the air intake box, the gas first enters the primary screener through the air port of the primary screener; the gas filtered by the primary screener comes out from the air port at the other end of the primary screener; then the gas comes to the dust reduction box, which is equipped with a dust reducer. The gas enters from the channel of the dust reducer. There is a nozzle inside the channel, which will spray atomized water droplets. These atomized water droplets will come into contact with the gas entering the channel and capture the fine dust in the gas; the gas after passing through the channel is relatively pure.

[0009] A further improvement of the technical solution of the utility model is that a cleaning scraper is slidably provided inside the channel, a connecting rod is fixedly provided on one side of the cleaning scraper, and an electric push rod is fixedly provided on one end of the connecting rod.

[0010] The above-mentioned technical solution is adopted, in which the nozzle sprays atomized water droplets to contact the dust in the gas. The gravity of the dust captured by the water droplets increases and it will fall into the channel. After a long time, it will accumulate inside the channel and affect the passage of gas. By setting a cleaning scraper, when the device has processed the dust once, the cleaning scraper will scrape the channel along the channel by starting the electric push rod, thereby scraping the accumulated dust in the channel and entering the collection box for collection.

[0011] A further improvement of the technical solution of the utility model is that: the channel is tapered, and the opening on one side close to the air intake box is larger than the opening on the other side.

[0012] The above-mentioned technical solution is adopted. In this solution, the channel is set to be conical. When the airflow enters the channel from one end, the dust will be restricted by the channel wall in the conical channel, thereby gradually slowing down and accelerating in the channel, and finally gathering at the small mouth end of the channel, making the cleaning and collection of dust more convenient.

[0013] A further improvement of the technical solution of the utility model is that an activated carbon adsorber is slidably provided on one side of the dust collector away from the air inlet box, and an activated carbon adsorption layer is provided in the activated carbon adsorber.

[0014] The above technical solution is adopted. In this solution, an activated carbon adsorber is set up. The gas discharged from the dust suppressor will enter the activated carbon adsorber. The activated carbon adsorber is provided with an activated carbon adsorption layer. The activated carbon can absorb pollutants such as dust in the air to ensure that the discharged gas will not pollute the air.

[0015] A further improvement of the technical solution of the utility model is that the channel is inclined at 30 degrees to the horizontal plane, and the height from one end of the channel close to the air inlet box to the bottom of the dust reduction box is greater than the distance from the other end to the bottom of the dust reduction box.

[0016] The above technical solution is adopted. In this solution, the channel is tilted. When the dust is captured by the water sprayed from the nozzle and falls into the channel, because the channel is tilted, under the action of gravity, the dust will slide down the slope with the residual water flow and then enter the collection box to complete the collection.

[0017] A further improvement of the technical solution of the utility model is that the primary screener includes a shell, air ports are provided at both ends of the shell, a plurality of dust filter elements are provided inside the shell, the dust filter elements can absorb large particles of dust, and a collection bucket is provided below the dust filter elements.

[0018] The above technical solution is adopted, in which a plurality of dust removal filters are arranged in the primary screener, and these dust removal filters can initially filter out the larger dust particles in the gas, and the filtered dust will fall into the funnel under the action of gravity to be collected.

[0019] The further improvement of the technical solution of the utility model is that: a motor is fixedly provided above the water tank, the motor is fixedly connected to the dust collector; the dust collector is rotatably connected to the dust reduction box.

[0020] The above technical solution is adopted. In this solution, a motor is set up, which drives the dust collector to rotate. When the dust-laden airflow enters the channel, the airflow will change from linear motion to circular motion. Dust particles with a density greater than that of the gas will lose their inertia when they come into contact with the wall of the device and fall along the wall. Water droplets are then sprayed out through the nozzle, causing the dust to settle. In this way, the dust can be settled more completely.

[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0022] 1. The utility model provides a solid waste dust collection device. After the gas enters the air inlet box, it first enters the primary screener through the air port of the primary screener; the gas filtered by the primary screener comes out from the air port at the other end of the primary screener; then the gas comes to the dust reduction box, which is provided with a dust reducer. The gas enters from the channel of the dust reducer, and a nozzle is provided inside the channel. The nozzle will spray atomized water droplets, which will contact the gas entering the channel and capture fine dust in the gas; the dust sedimentation is more efficient.

[0023] 2. The utility model provides a solid waste dust collection device, in which a nozzle sprays atomized water droplets which come into contact with dust in the gas. The dust captured by the water droplets has a greater gravity and falls into the channel. Over time, the dust accumulates inside the channel, affecting the passage of gas. By arranging a cleaning scraper, after the device has processed the dust once, the electric push rod is started, and the cleaning scraper scrapes the channel along the channel, thereby scraping the accumulated dust in the channel and entering the collection box for collection.

[0024] 3. The utility model provides a solid waste dust collection device. By setting a motor, the motor will drive the dust collector to rotate. When the dust-laden airflow enters the channel, the airflow will change from linear motion to circular motion. Dust particles with a density greater than that of the gas will lose their inertia when in contact with the wall of the device and fall along the wall, and then water droplets will be sprayed out through the nozzle to settle the dust. In this way, the dust can be settled more completely. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In this embodiment, when the device is used, the pipeline for conveying dust-containing gas is first connected to the air inlet 3, and the dust-containing gas enters the air inlet box 1 through the air inlet 3; after the gas enters the air inlet box 1, it first enters the primary screener 4 through the air port of the primary screener 4; the gas filtered by the primary screener 4 comes out from the air port at the other end of the primary screener 4; then the gas comes to the dust reduction box 2, and the dust reduction box 2 is provided with a dust reducer 5, and the gas enters from the channel 6 of the dust reducer 5, and a nozzle 8 is provided inside the channel 6, which will spray atomized water droplets, and these atomized water droplets will contact the gas entering the channel 6 and capture the fine dust in the gas; the gas after passing through the channel 6 is relatively pure.

[0037] The nozzle 8 sprays atomized water droplets which come into contact with the dust in the gas. The gravity of the dust captured by the water droplets increases and the dust falls into the channel 6. After a long time, the dust accumulates inside the channel 6, affecting the passage of the gas. By setting a cleaning scraper 14, when the device has processed the dust once, the cleaning scraper 14 will scrape the channel 6 along the channel 6 by starting the electric push rod, thereby scraping the accumulated dust in the channel 6 and entering the collection box 9 for collection.

[0038] Preferably, the channel 6 is tapered, and the opening on the side close to the air intake box 1 is larger than the opening on the other side.

[0039] By setting the channel 6 to be conical, when the airflow enters from one end of the channel 6, in the conical channel 6, the dust will be restricted by the wall of the channel 6, thereby gradually slowing down and accelerating in the channel 6, and finally gathering at the small end of the channel 6, making the cleaning and collection of dust more convenient.

Dust particles with a density greater than that of the gas will lose their inertial force and fall along the wall when they come into contact with the wall, and then water droplets are sprayed out through the nozzle, so that the dust is settled. In this way, the dust is settled more completely.

[0050] The working principle of the solid waste dust collection device is described in detail below.

[0051] like Figure 1-5As shown, when using the device, first connect the pipeline for conveying dust-containing gas to the air inlet 3, and the dust-containing gas enters the air inlet box 1 through the air inlet 3; after entering the air inlet box 1, the gas first enters the primary screener 4 through the air port of the primary screener 4; the gas filtered by the primary screener 4 comes out from the air port at the other end of the primary screener 4; then the gas comes to the dust reduction box 2, which is provided with a dust collector 5, and the gas enters from the channel 6 of the dust collector 5, and the channel 6 is provided with a nozzle 8, which will spray atomized water droplets; the motor 13 will drive the dust collector 5 to rotate, and when the dust-containing airflow enters the channel 6, the airflow will change from linear motion to circular motion.
