DETAILED DESCRIPTION

[0035] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present application and are not limited to the scope of the present application. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0036] Example 1 like Figures 1 to 7 As shown, the industrial production dust collector of the present invention specifically includes a support frame 1, a separation barrel 2, an air outlet pipe 3, a discharge valve 8, a separation mechanism 4, and a filter press mechanism 5; A separation barrel 2 is provided on the upper part of the support frame 1, an air outlet pipe 3 is provided on the top of the separation barrel 2, and a discharge valve 8 is provided at the bottom of the separation barrel 2 for separating dust from the dust-laden airflow; The separation mechanism 4 is arranged inside the separation barrel 2 to assist in accelerating the filtration of large smoke particles; The filter pressing mechanism 5 is arranged at the bottom of the air outlet pipe 3, and is used for filtering, squeezing and enriching the smoke dust driven by the airflow.

[0037] The separation mechanism 4 specifically includes a rotating shaft 402, a wind wheel 403, a spiral impeller 404 and a first filter screen 405; A fixing frame 401 is provided inside the separation barrel 2 and the air outlet pipe 3, a rotating shaft 402 is rotatably provided between the fixing frame 401 of the separation barrel 2 and the air outlet pipe 3, and a wind wheel 403 is provided on the upper part of the rotating shaft 402 for providing power for the rotation of the rotating shaft 402; A spiral impeller 404 is provided in the middle of the rotating shaft 402 to push large dust particles in the airflow downward to assist in filtering; There are multiple through holes evenly spaced apart on the surface of the spiral impeller 404, and a first filter 405 is provided in each of the through holes of the spiral impeller 404 for filtering the air flow toward the air outlet pipe and filtering and enriching the dust carried by the air flow.

[0038] The filter press mechanism 5 specifically includes a second filter screen 501, a first fixed shell 502, a sliding frame 503, a top plate 504, a collecting frame 505, a first elastic member 506 and an electric push rod 507; Among them, a second filter screen 501 is provided at one end of the air outlet pipe 3 located in the separation barrel 2, which is used to filter the dust in the air flow for the second time; Among them, a first fixed shell 502 is provided at one end of the air outlet pipe 3 located in the separation barrel 2, and the first fixed shell 502 is located at the lower part of the second filter screen 501. Sliding frames 503 are symmetrically slidably penetrated on both sides of the first fixed frame 401, and a top plate 504 is provided at one end of the two sliding frames 503 close to each other. Electric push rods 507 are provided at positions close to the two sliding frames 503 on the side wall of the separation barrel 2. The telescopic rods of the two electric push rods 507 are connected to the close sliding frames 503, which are used to scrape the dust on the surface of the second filter screen 501 and squeeze it into blocks; A collecting frame 505 is slidably provided on the sliding frame 503, and a protrusion penetrating the top plate 504 is provided on one side of the collecting frame 505 close to the top plate 504. A first elastic member 506 is provided between the collecting frame 505 and the top plate 504, and is used to collect the dust after the dust is scraped off the second filter 501, so as to facilitate subsequent squeezing into blocks; For example, when in use, the staff connects the suction duct to the air inlet duct on the upper part of the separation barrel 2, and connects the air outlet pipe 3 to the external fan. After starting the fan, the dust-laden airflow is sucked into the separation barrel 2 through the suction duct. Since the air inlet pipe of the separation barrel 2 is offset from the center of the separation barrel 2, when the dust-laden airflow enters the separation barrel 2, the dust-laden airflow rotates downward along the barrel wall, and large dust particles are separated from the airflow and captured on the wall by centrifugal force. Then, the dust particles fall into the discharge valve 8 for enrichment by gravity, and the filtered gas leaves the separation barrel 2 from the air outlet pipe 3 due to the cylinder structure, thereby achieving the purpose of cleaning the powder. The first filter 405 on the spiral impeller 404 can assist in separating large dust particles from the airflow, and when the airflow enters the air outlet pipe 3 upward, it will pass through the first filter 405, so as to achieve the effect of filtering the dust in the airflow that is driven upward and drifting. When the airflow enters the air outlet pipe 3, the second filter 501 at the outlet pipe 3 can filter the dust in the airflow for the second time. By setting a second filter 501 with a smaller aperture than the first filter 405, the effect of further filtering the dust in the airflow is achieved. At the same time, in the initial state, the telescopic rod of the electric push rod 507 is in a retracted state. After the device has been running for a period of time, the staff controls the two electric push rods 507 to start at the same time, and pushes the two sliding frames 503 closer to each other. When the two top plates 504 approach each other, the dust on the second filter 501 is scraped off and accumulated in the collection frame 505. When the two top plates 504 approach each other, the collection frames 505 on the two sliding frames 503 first contact each other to form a square frame. The two top plates 504 are continued to be driven closer to each other, the first elastic member 506 is stretched, and the dust scraped off is then squeezed into blocks by the two top plates 504 that continue to approach each other to prevent it from being driven up by the airflow again. After the squeezing is completed, the electric push rod 507 retracts the telescopic rod back to the initial position, and the collecting frame 505 is moved closer to the top plate 504 under the action of the first elastic member 506, and the dust blocks are pushed into the separation barrel 2 through the protrusions on the collecting frame 505, thereby achieving the effect of enriching and removing the dust accumulated at the bottom of the second filter screen 501 due to the airflow when the device is running, thereby preventing excessive dust from clogging the second filter screen 501.To summarize, the device drives the dust into the separation barrel 2 through the airflow, separates the large dust particles by rotating the dust-laden airflow in the separation barrel 2, and drives the spiral impeller 404 to rotate through the airflow through the wind wheel 403 to assist in the separation of the large dust particles. Then, when the airflow passes through the first filter screen 405 upward and enters the exhaust pipe 3, the fine dust particles driven upward by the airflow are filtered for the first time. When the airflow passes through the second filter screen 501 in the exhaust pipe 3, the fine dust particles in the airflow are filtered for the second time. After the device has been running for a period of time, the electric push rod 507 controls the top plate 504 to scrape off the dust at the bottom of the second filter screen 501 and squeeze it into blocks, which are then pushed into the separation barrel 2 for collection, thereby ensuring the effect of collecting the dust.

[0039] Example 2 like Figures 8 to 10 As shown, on the basis of Example 1, it also includes a vibration mechanism 6, which specifically includes a fixing ring 601, a collision rod 602, an extrusion column 603 and a second elastic member 604. The upper and lower parts of the spiral impeller 404 are both provided with fixing rings 601, and a spiral collision rod 602 is slidably provided in the middle part of the spiral impeller 404. The upper and lower ends of the collision rod 602 are respectively located on the upper and lower parts of the fixing ring 601 of the spiral impeller 404, and a plurality of extrusion columns 603 are evenly spaced in an annular manner on the top of the collision rod 602. The extrusion columns 603 are extruded and matched with the fixing frame 401 on the upper part of the separation barrel 2, and a plurality of second elastic members 604 are provided between the collision rod 602 and the fixing ring 601.

[0040] During the rotation of the spiral impeller 404, the spiral impeller 404 drives the collision rod 602 to rotate together. When the extrusion column 603 approaches the fixed frame 401 on the upper inner side of the separation barrel 2, the extrusion column 603 is squeezed downward, driving the collision rod 602 to squeeze the second elastic member 604 to move downward. When the extrusion column 603 is away from the fixed frame 401, the extrusion column 603 is driven to move upward under the resetting action of the second elastic member 604. When the spiral impeller 404 rotates at a faster speed, the extrusion rod and the fixed frame 401 repeatedly and quickly contact and move away. Under the action of the second elastic member 604, the collision rod 602 continuously collides with the spiral impeller 404, thereby achieving the effect of vibrating the surface of the spiral impeller 404 to clean dust.

[0041] like Figure 11 to Figure 15As shown, on the basis of Example 1, it also includes a filtering mechanism 7, which specifically includes a third filter screen 701, a scraper wheel 702, a second fixed shell 704, a convex plate 705, a fourth elastic member 7051, a material accumulation frame 706, a clamping plate 707, a third elastic member 708 and an elastic protrusion 709. The third filter screen 701 is provided on the inner side of the air outlet pipe 3, and a scraper wheel 702 is provided on the rotating shaft 402 between the second filter screen 501 and the third filter screen 701. The air outlet pipe 3 is symmetrically provided with leakage ports 703 on both sides of the horizontal height of the scraper wheel 702. A second fixed shell 704 is provided on the outer side of the air outlet pipe 3 near the leakage port 703. The second fixed shell 704 completely covers the leakage port 703. A convex plate 705 is provided at the upper part in a sliding manner, and a fourth elastic member 7051 is provided between the convex plate 705 and the second fixed shell 704; a material accumulation frame 706 is provided at the lower part of the second fixed shell 704 in a sliding manner, and the material accumulation frame 706 is connected to the convex plate 705, and through holes are provided at the top and the bottom of the material accumulation frame 706; a clamping plate 707 is provided at the inner side of the material accumulation frame 706 in a sliding manner, and the clamping plate 707 is in contact with the second fixed shell 704, and a third elastic member 708 is provided between the clamping plate 707 and the second fixed shell 704; elastic protrusions 709 are symmetrically provided between the two side surfaces of the clamping plate 707 in contact with the second fixed shell 704, and grooves for limiting the elastic protrusions 709 are symmetrically provided between the positions of the second fixed shell 704 in contact with the clamping plate 707.

[0042] When the device is running, the third filter screen 701 in the air outlet pipe 3 filters the airflow for the third time, further filtering the finer dust in the airflow, and the rotating shaft 402 drives the scraper wheel 702 to rotate, and the scraper wheel 702 scrapes the dust filtered by the third filter screen 701 and enters the second fixed shell 704 from the leakage port 703 of the air outlet pipe 3. When the scraper wheel 702 is not in contact with the convex plate 705, the convex plate 705 is completely retracted in the second fixed shell under the action of the third elastic member 708. 704, the material accumulation frame 706 is located in the second fixed shell 704, the clamping plate 707 is restricted on the second fixed shell 704 under the action of the elastic protrusion 709, the fourth elastic member 7051 is in a compressed state, and the dust enters the material accumulation frame 706 from the leakage port 703 and accumulates. When the scraper wheel 702 rotates to squeeze the convex plate 705, the convex plate 705 and the material accumulation frame 706 are driven to move to the outside of the second fixed shell 704, and the clamping plate 707 is restricted on the second fixed shell 704 by the convex protrusion of the elastic member. The dust in the material accumulation frame 706 is first squeezed into blocks, and then the convex plate 705 is driven to move outward, the force on the clamping plate 707 increases, and the elastic protrusion 709 is deformed, and finally the material accumulation frame 706 and the clamping plate 707 are extended from the second fixed shell 704. The clamping plate 707 moves to the edge of the material accumulation frame 706 under the action of the fourth elastic member 7051 and is limited by the long strip on the material accumulation frame 706. The block protrusions fall out of the through holes at the bottom of the material accumulation frame 706. When the scraper wheel 702 and the convex plate 705 are moved, the dust in the material accumulation frame 706 is squeezed into blocks. When the contact is lost, the convex plate 705 moves back to the initial position under the action of the third elastic member 708, and the material accumulation frame 706 drives the clamping plate 707 to move into the second fixed shell 704 through the long strip, and finally the clamping plate 707 and the elastic protrusion 709 are re-stuck in the second fixed shell 704. When the device is running, the scraper wheel 702 continues to rotate, and the convex plate 705 is repeatedly driven to move in the second fixed shell 704, so as to achieve the effect of repeatedly and continuously discharging the dust filtered by the third filter screen 701 into the separation barrel 2.

[0043] like Figure 2 As shown, based on the embodiment 1, a spiral blade 9 is further included. The bottom of the rotating shaft 402 is provided with a spiral blade 9.

[0044] The spiral blades 9 at the bottom of the rotating shaft 402 can squeeze and push downward the dust accumulated at the bottom of the separation barrel 2 to ensure that the dust is discharged from the separation barrel 2.

[0045] like Fig.16 and Fig.17 As shown, on the basis of embodiment 1, a protection tube 10 is further included, and a protection shell which completely covers the collision rod 602 is provided in the middle of the spiral impeller 404 .

[0046] The protective shell on the spiral impeller 404 can cover the collision rod 602 and the second elastic member 604 to isolate dust from the collision rod 602 and prevent dust from accumulating on the surface of the collision rod 602 and the second elastic member 604 to affect the collision effect.

Under the action of negative pressure, the dust-laden airflow enters the separation barrel 2 through the external air intake duct, and then is filtered by the device. The air passes through the separation barrel 2 and the air outlet pipe 3 and is discharged outside. Step 4: After the device has been running for a period of time, when a certain amount of dust accumulates on the second filter 501, the telescopic rod of the electric push rod 507 is controlled to extend and retract two or three times to scrape and discharge the dust on the second filter 501; Step 5: Repeat the above steps to achieve the treatment of particulate matter.
