Description

Technical Field

[0001] This utility model relates to the field of crushing technology for household appliance recycling, and in particular to a crushing device for household appliance recycling with a dust removal structure. Background Technology

[0002] Waste electrical and electronic products are a special type of solid waste. If they are buried directly, the harmful substances in them will seep in and seriously pollute the soil. If they are incinerated, they will release a large amount of harmful gases, pollute the air, and endanger people's health. However, after centralized collection, dismantling, and disposal, these waste appliances can be transformed into high-purity renewable resources, such as plastics and various metals. Therefore, the recycling and utilization of waste electrical and electronic products is of great importance.

[0003] In the process of recycling waste household appliances, crushing equipment is one of the key pieces of equipment. At present, although various crushing equipment for household appliance recycling has been developed at home and abroad, which can effectively crush waste household appliances to meet the needs of subsequent processing, these devices generally have a serious problem. When crushing household appliance recycling materials, a large amount of dust is generated due to the violent crushing of the materials. For example, dust is constantly generated and spreads to the surroundings at the feed inlet and discharge outlet of the crusher and during the material conveying process. On the one hand, this will lead to extremely serious dust pollution at the processing site, which will not only affect the working environment, but may also endanger the health of the operators. On the other hand, the spread of dust may also pollute the surrounding environment. Utility Model Content

[0004] In order to overcome the problem that existing crushing devices for household appliance recycling generate a large amount of dust when crushing household appliance recycling materials, causing serious dust pollution at the processing site, this utility model provides a crushing device for household appliance recycling with a dust removal structure.

[0005] The technical solution is as follows: a crushing device for recycling household appliances with a dust removal structure, including a crushing component and a dust removal component; a dust removal component is provided on one side of the crushing component; the crushing component includes a crusher, a recycling hopper, a first dust conveying pipe, a dust separation screen, and a solid fragment recycling pipe; the dust removal component includes a dust removal tank, a blower, a second dust conveying pipe, a filter bag, and an air vent.

[0006] Furthermore, a recovery hopper is provided at the lower end of the crusher, and the recovery hopper is connected to the discharge end of the crusher; a first dust conveying pipe is provided at the lower end of the recovery hopper, and the first dust conveying pipe is fixedly connected to the lower port of the recovery hopper.

[0007] Furthermore, a dust separation screen is installed inside the recycling hopper, and the dust separation screen is bolted to the inner wall of the recycling hopper. The dust separation screen is inclined with the front higher than the back. A solid debris recycling pipe is installed behind the dust separation screen, and the material inlet of the solid debris recycling pipe is located at the upper rear end of the dust separation screen.

[0008] Furthermore, a blower is provided on one side of the crusher; a dust collection tank is provided on one side of the blower, and the first dust conveying pipe is connected to the input end of the blower.

[0009] Furthermore, a second dust conveying pipe is provided at the output end of the blower, and the output end of the second dust conveying pipe is located inside the dust collection tank.

[0010] Furthermore, the dust collector is equipped with a filter bag inside, and the inlet end of the filter bag is connected to the second dust conveying pipe by a flange seal.

[0011] Furthermore, a vent pipe is provided at the lower end of the dust collector, and the vent pipe is fixedly connected to the dust collector.

[0012] The beneficial effects are as follows: This utility model uses a dust separation screen in the recycling hopper to screen the crushed material discharged from the crusher. Large particles of material accumulate and slide down with the inclined dust separation screen, and are discharged and collected through the solid fragments recycling pipe. Fine dust passes through the screening holes of the dust separation screen and, due to the suction of the blower, the dust particles enter the blower along the first dust conveying pipe and are then blown into the interior of the filter bag along the second dust conveying pipe. The filter bag filters and collects the dust in the airflow, which greatly reduces the dust rate when the household appliance recycling and crushing equipment is working and improves the environmental protection production and processing effect.

[0013] By installing a vent pipe, the airflow inside the filter bag is discharged, thereby improving the filter bag's efficiency in filtering dust from the airflow and increasing the airflow speed inside the filter bag. Attached Figure Description

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figures 1-5 As shown, a household appliance recycling crushing device with a dust removal structure includes a crushing component 1 and a dust removal component 2; the dust removal component 2 is provided on one side of the crushing component 1; the crushing component 1 includes a crusher 101, a recycling hopper 102, a first dust conveying pipe 103, a dust separation screen 104, and a solid fragment recycling pipe 105; the dust removal component 2 includes a dust removal tank 201, a blower 202, a second dust conveying pipe 203, a filter bag 204, and a ventilation pipe 205.

[0023] The lower end of the crusher 101 is provided with a recycling hopper 102, and the recycling hopper 102 is connected to the discharge end of the crusher 101; the lower end of the recycling hopper 102 is provided with a first dust conveying pipe 103, and the first dust conveying pipe 103 is fixedly connected to the lower port of the recycling hopper 102.

[0024] The recycling hopper 102 is equipped with a dust separation screen 104, which is bolted to the inner wall of the recycling hopper 102. The dust separation screen 104 is inclined with the front higher than the back. A solid debris recycling pipe 105 is provided behind the dust separation screen 104, and the material inlet of the solid debris recycling pipe 105 is located at the upper rear end of the dust separation screen 104.

[0025] A blower 202 is provided on one side of the crusher 101; a dust collection tank 201 is provided on one side of the blower 202, and the first dust conveying pipe 103 is connected to the input end of the blower 202.

[0026] The blower 202 is provided with a second dust conveying pipe 203 at its output end, and the output end of the second dust conveying pipe 203 is located inside the dust collection tank 201.

[0027] The dust collector 201 is equipped with a filter bag 204 inside, and the inlet end of the filter bag 204 is connected to the second dust conveying pipe 203 by a flange seal.

[0028] The dust separation screen 104 of the recycling hopper 102 screens the crushed material discharged from the crusher 101. Large particles accumulate and slide down the inclined dust separation screen 104, and are discharged and collected through the solid fragments collection pipe 105. Fine dust passes through the screening holes of the dust separation screen 104 and, due to the suction of the blower 202, the dust particles enter the blower 202 along the first dust conveying pipe 103 and are then blown into the interior of the filter bag 204 along the second dust conveying pipe 203. The filter bag 204 filters and collects the dust in the airflow, greatly reducing the dust rate during the operation of the household appliance recycling and crushing equipment and improving the environmental protection production and processing effect.

[0029] Example 2

[0030] Based on Example 1, such as Figures 1-5 As shown, a vent pipe 205 is provided at the lower end of the dust collector 201, and the vent pipe 205 is fixedly connected to the dust collector 201.

[0031] By setting the vent pipe 205, the vent pipe 205 is used to discharge the airflow inside the filter bag 204, thereby improving the efficiency of the filter bag 204 in filtering dust in the airflow and increasing the airflow speed inside the filter bag 204.
