Description

Technical Field

[0001] The utility model relates to a kitchen waste treatment system, in particular to a waste gas treatment device for solid waste. Background Art

[0002] After the kitchen waste is crushed, biologically fermented and heated, the waste gas must be filtered before being discharged.

[0003] At present, a Chinese patent with authorization announcement number CN215352891U discloses a waste gas treatment device in a garbage treatment equipment, including a spray tower and a photo-oxygen purifier. An air inlet is provided at the lower end of the spray tower, an air outlet is provided at the upper end of the spray tower, a plurality of nozzles are installed on the inner wall of the spray tower, a pipe is provided between the air outlet and the photo-oxygen purifier for communication, the pipe is bent downward to form a concave section, a drain is provided at the lowest point of the concave section, the waste gas enters the spray tower through the air inlet, the nozzle discharges water and sprays the waste gas, and the waste gas after spraying enters the pipe with a large amount of water, and finally leads to the photo-oxygen purifier.

[0004] Its working principle: the exhaust gas enters the spray tower through the air inlet, the nozzle discharges water and sprays the exhaust gas, the exhaust gas passes through multiple layers of filter ball layers in turn, the solid impurities contained in the exhaust gas are absorbed, and the exhaust gas after spraying enters the pipeline with a large amount of water, and finally leads to the photo-oxygen purifier. In this process, the water will condense in the pipeline to form small water droplets. The drain outlet is opened at the lowest point of the concave section of the pipeline, so that under the action of gravitational potential energy, the small water droplets will gather to the drain outlet and be discharged through the drain outlet. When drainage is not needed, the plug can be plugged to prevent the exhaust gas from escaping.

[0005] However, after the kitchen waste undergoes biological fermentation and heating, there will be a large amount of dust in the waste gas generated. Before the waste gas enters the spray tower, a cloth bag is usually used to absorb the dust. The water vapor in the waste gas will also be adsorbed on the cloth bag. The dust and water vapor will be mixed into a sticky state on the cloth bag, and then solidify and agglomerate on the cloth bag, making it inconvenient to clean the cloth bag. Utility Model Content

[0006] In view of this, the utility model aims to provide a waste gas treatment device for solid waste to achieve the purpose of easy cleaning.

[0007] In order to solve the above technical problems, the technical solution of the utility model is: a waste gas treatment device for solid waste, comprising a spray tower, a plasma photo-oxygen catalyst, and an exhaust fan, the spray tower is connected to a biological fermentation box and a plasma photo-oxygen catalyst, the exhaust fan is connected to the plasma photo-oxygen catalyst, a filter box is arranged between the spray tower and the biological fermentation box, one end of the filter box is connected to the biological fermentation box through an air inlet, and the other end is connected to the spray tower through an air outlet, a cleaning port is provided on one side of the filter box, a sealing plate is connected to the cleaning port, an installation groove is provided on the sealing plate, a filter plate located in the filter box is penetrated in the installation groove, a filter hole is provided on the filter plate, and the air inlet and the air outlet are respectively located on both sides of the filter plate.

[0008] To implement the above technical solution, when the exhaust fan is started, the waste gas in the biological fermentation box enters the filter box from the air inlet, and after being filtered by the filter plate, the waste gas enters the spray tower from the air outlet, and then passes through the plasma photo-oxidation catalyst and is discharged from the exhaust fan. The water vapor and dust in the filter box are mixed on the filter plate and slide along the filter plate to the bottom wall of the filter box. After removing the sealing plate from the cleaning port, the garbage can be cleaned out from the cleaning port. The operation is simple. When the filter plate is blocked, the filter plate can be pulled out of the installation groove to clean the filter plate. After cleaning, the filter plate can be inserted into the filter box along the installation groove to complete the installation.

[0009] As a preferred solution of the utility model, the end of the filter plate is connected to a connecting plate, the connecting plate is located outside the filter box, and a connecting groove is opened on the surface of the connecting plate.

[0010] To implement the above technical solution, the filter plate can be easily pulled out from the filter box by passing the hand through the connection groove and holding the connection plate.

[0011] As a preferred solution of the utility model, a limiting assembly for limiting the position of the filter plate is arranged between the inner wall of the filter box and the filter plate, and a plurality of the filter plates are arranged in parallel.

[0012] To implement the above technical solution, after the exhaust fan is started, when the filter holes on the filter plate are partially blocked, the wind pressure on the filter plate increases, and the limiting action of the limiting assembly prevents the filter plate from being easily deformed or damaged.

[0013] As a preferred solution of the utility model, the limiting assembly includes a limiting plate and a limiting groove. The limiting plate is fixedly connected to the inner wall of the filter box. The two limiting plates are arranged opposite to each other. The limiting groove is opened on the limiting plate. The length direction of the limiting groove is parallel to the length direction of the limiting plate. The upper and lower edges of the filter plate are slidably connected to the limiting groove.

[0014] To implement the above technical solution, the filter plate is passed through the installation groove and then placed in the limiting groove. The inner wall of the limiting groove abuts against the side wall of the filter plate, thereby supporting the filter plate and preventing the filter plate from being deformed.

[0015] As a preferred solution of the utility model, the limiting component also includes an anti-slip groove, an anti-slip recessed hole and an anti-slip spring sheet. The anti-slip groove is arranged on the side wall of the limiting plate and is connected to the limiting groove. The anti-slip spring sheet is arranged in an arc shape and both ends are fixed on the inner wall of the anti-slip groove. The anti-slip recessed hole is arranged on the side wall of the filter plate, and the middle part of the anti-slip spring sheet is embedded in the anti-slip recessed hole.

[0016] To implement the above technical solution, the filter plate is inserted into the filter box along the installation groove, so that the upper and lower edges of the filter plate are placed in the limit grooves. As the filter plate continues to move, when the anti-dropout recessed hole corresponds to the anti-dropout spring sheet, the middle part of the anti-dropout spring sheet is embedded in the anti-dropout recessed hole, generating a certain friction force, thereby making the filter plate more stable in the limit groove.

[0017] As a preferred solution of the utility model, a plurality of filter holes are provided, and the plurality of filter holes are arranged in an L shape, and the filter holes are located at one end of the filter plate away from the connecting plate and close to the upper edge of the filter plate.

[0018] To implement the above technical solution, since the mass of dust is greater than the mass of air, most of the dust can be blocked by the filter plate and cannot pass through the filter holes, thereby reducing the cleaning frequency of the filter plate.

[0019] As a preferred solution of the utility model, the sealing plate is connected to the filter box through a positioning mechanism.

[0020] The above technical solution is implemented to make the connection between the sealing plate and the filter box more stable, and the sealing plate is not easily dislodged from the filter box during the process of pulling the filter plate.

[0021] As a preferred solution of the utility model, the positioning mechanism includes a positioning ring, a sealing ring, and a sealing groove. The positioning ring is fixed to the side of the sealing plate facing the filter box, the sealing groove is opened on the outer wall of the positioning ring, the sealing ring is embedded in the sealing groove, and the outer wall of the sealing ring is tightly pressed against the inner wall of the filter box.

[0022] To implement the above technical solution, the sealing plate is brought into contact with the filter box, the positioning ring is located in the cleaning port, and the outer wall of the sealing ring is brought into contact with the inner wall of the filter box to generate a large friction force to achieve the positioning of the sealing plate. In addition, due to the sealing effect of the sealing ring, it is difficult for the exhaust gas to leak out of the gap between the sealing plate and the filter box.

[0023] As a preferred solution of the utility model, a storage tank is connected to the bottom wall of the filter box, and a waste outlet is provided on the bottom wall of the storage tank.

[0024] By implementing the above technical solution, the sticky garbage formed by water vapor and dust falls into the storage tank along the surface of the filter plate, and the garbage can be directly discharged through the waste outlet, which is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS
