Description

Technical Field

[0001] The utility model relates to the technical field of tire recycling and processing, in particular to a crushing and dust removal device for recycling waste tires. Background Art

[0002] Tire rubber must be wear-resistant, prevent aging, be waterproof, and have shock absorption, so it is a huge waste of resources to discard waste tires as garbage. If the waste tires are crushed by physical means, rubber particles, rubber powder, and steel wire can be obtained after processing. These rubbers can be used in many fields, such as roadbed paving, rubber runways, various rubber products, etc. Rubber tires will be crushed when they are recycled. After crushing, they will be screened to remove impurities such as iron nails and iron wires inside. A large amount of dust will appear during the screening process, polluting the working environment. Some filtering equipment filters through filter nets. The filter nets will be blocked when used for a long time, affecting the filtering efficiency. The staff needs to frequently replace the filter nets, which is time-consuming and labor-intensive.

[0003] At present, there is an existing waste tire recycling crushing and dust removal device (such as patent number: CN220656929U), which discloses a waste tire recycling crushing and dust removal device, including a mounting frame, the upper wall of the mounting frame crossbeam is equipped with a filtering structure, and the lower wall of the mounting frame crossbeam is equipped with a swinging structure. The utility model realizes automatic bending and extraction of dust and filtering the dust in the dust by fusion with water, and then filtering the odor and other impurities through the activated carbon filter layer, with good filtering effect and large extraction area.

[0004] However, in the process of implementing the above technical solution, it was found that there are at least the following technical problems: the existing device blows the dust toward the water tank through the fan. One problem with this method is that when the fan is running at high speed, the internal spiral blades will also hit the dust when rotating at high speed. Under the friction of the dust for a long time, the spiral blades of the fan will wear quickly, causing damage to the fan. Therefore, there is room for improvement in the installation position of the fan of the existing device, and there is a problem of easy damage. Utility Model Content

[0033] An observation window 203 is fixedly mounted on the same surface of the box body 1 where the water outlet 201 and the water inlet 202 are mounted. A scale is provided on the observation window 203 . A water level line 204 is fixedly opened in the middle of the observation window 203 . The height of the water level line 204 is lower than the water inlet 202 .

[0034] The mounting frame 3 and the inner wall of the box body 1 are fixedly connected to two limit members 301, a filter screen 303 is slidably connected between the two limit members 301, a sealing ring 302 is fixedly connected to the inner wall of one end of the mounting frame 3 away from the limit members 301, and a baffle 304 is provided at the end of the mounting frame 3 away from the box body 1, and four screws 305 are sleeved on the baffle 304.

[0035] Four screws 305 pass through one end of the baffle 304 and are threadedly connected to the mounting frame 3. A handle 307 is fixedly installed on the end of the filter 303 close to the baffle 304. A sealing plate 306 is fixedly installed on the end of the baffle 304 close to the filter 303. The sealing plate 306 is squeezed and contacted with the handle 307, and the sealing plate 306 is also squeezed and connected with the sealing ring 302.

[0036] A cover plate 104 is fixedly installed on the top surface of the box body 1, and two activated carbon filters 4 are fixedly installed on the cover plate 104. The two activated carbon filters 4 are fixedly connected to an air guide pipe 401 at one end close to the cover plate 104. The air guide pipe 401 passes through the cover plate 104 and extends to the inner side of the box body 1.

[0037] One end of the shunt pipe 5 away from the activated carbon filter 4 is fixedly connected to a high-pressure fan 6 , and the high-pressure fan 6 is fixedly installed on the top surface of the fixed plate 7 .

[0038] The inner bottom surface of the box body 1 carries water, and the height of the water surface is flush with the height of the water level line 204 , the height of the water surface is lower than the air inlet 102 , and the height of the water surface is higher than the bottom surface of the partition 101 .

[0039] First, the device is assembled above the screening equipment. Dust is generated during the screening process of the screening equipment. The high-pressure fan 6 is started. The high-pressure fan 6 draws the air from the shunt pipe 5, and then draws the air in the box 1 through the shunt pipe 5 and the activated carbon filter 4, so that a negative pressure is formed in the box 1. When the negative pressure reaches a certain level, the negative pressure in the box 1 is transmitted through the water surface to the side of the partition 101 away from the mounting frame 3, and the air is transmitted to the box 1 through the air inlet 102 to offset the negative pressure. While transmitting the air, the air inlet 102 will absorb the dust from the outside. The function of the safety net 103 is to prevent foreign objects from falling into the box 1. The dust will Most of the water passing through the bottom of the box body 1 is absorbed by the water, which plays a filtering role. Finally, under the continuous action of the high-pressure fan 6, bubbles will appear on the water on the side of the partition 101 close to the mounting frame 3. The bubbles contain the exhaust gas that has been preliminarily filtered. The exhaust gas passes through the filter net 303 for a second filtration under the pumping of the high-pressure fan 6 to completely filter out the dust. Finally, the exhaust gas passes through the activated carbon filter 4 to absorb the odor and other impurities in the exhaust gas, and finally enters the high-pressure fan 6 through the shunt pipe 5 and is discharged to the outside. At this time, the impurities in the exhaust gas are basically eliminated, the dust removal work is completed, and the technical problem that the existing device is easy to be damaged is solved.

[0040] Working principle:

[0041] The first step is to assemble the device above the screening equipment. During the screening process of the screening equipment, dust is generated. The high-pressure fan 6 is started. The high-pressure fan 6 draws the air from the shunt pipe 5, and then draws the air in the box 1 through the shunt pipe 5 and the activated carbon filter 4, so that negative pressure is formed in the box 1. When the negative pressure reaches a certain level, the negative pressure in the box 1 is transmitted through the water surface to the side of the partition 101 away from the mounting frame 3, and the air is transmitted to the box 1 through the air inlet 102 to offset the negative pressure. While transmitting the air, the air inlet 102 will absorb the dust from the outside. The function of the safety net 103 is to prevent foreign objects from falling into the box. Falling into the box body 1, the dust will pass through the water at the bottom of the box body 1, and most of it will be absorbed by the water, playing a filtering role. Finally, under the continuous action of the high-pressure fan 6, bubbles will appear in the water on the side of the partition 101 close to the mounting frame 3, and the bubbles contain the exhaust gas that has been preliminarily filtered. Under the pumping of the high-pressure fan 6, the exhaust gas passes through the filter net 303 for a second filtration to completely filter out the dust, and finally passes through the activated carbon filter 4 to absorb the odor and other impurities in the exhaust gas, and finally enters the high-pressure fan 6 through the shunt pipe 5 and is discharged to the outside. At this time, the impurities in the exhaust gas are basically eliminated, and the dust removal work is completed.

[0042] In the second step, the filter 303 will absorb a large amount of dust after filtering for a period of time, which may clog the interior of the box 1. The baffle 304 can be separated from the mounting frame 3 by removing the screws 305, and the filter 303 can be removed by pulling the handle 307. The sealing ring 302 cooperates with the sealing plate 306 to achieve a sealing effect. After removing the filter 303, it can be cleaned and reinstalled. The turbidity of the water in the box 1 can be observed through the observation window 203. After the water is completely contaminated, water can be drained and added through the water outlet 201 and the water inlet 202.

[0043] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
