It solves the problem that in the prior art, each filter screen is cleaned only by spraying water after the dust removal work is completed, and during the dust removal work, it is difficult to fully clean the more stubborn wood chip dust impurities adhering to the filter screen, and the cleaning force is weak, which is easy to affect the filtering and dust removal effect of the filter screen, and the deposited wood chip dust needs to be transported to the processing workshop for pressing treatment through a screw conveyor, and the process is cumbersome, which affects the work efficiency.

[0006] The invention is achieved in this way, a multi-stage dust collector in a wood processing workshop comprises a dust box, wherein two sides of the dust box are respectively fixedly connected with a dust inlet pipe and an air outlet pipe, wherein the interior of the dust box is fixedly connected with a partition, and two sides of the partition are respectively fixedly connected with a coarse filter screen and a glass fiber filter screen.

At the same time, through the coordinated action of the scraping mechanism and the brushing mechanism, the coarse filter, fine filter and glass fiber filter are timely cleaned to prevent blocking, and the cleaning force is strong and the effect is sufficient, thereby effectively improving the dust removal effect and quality.

By starting the dust suction fan, the wood chips and dust can be sucked into the dust removal box for dust removal. Starting the motor can drive the horizontal rotating rod to rotate, which is convenient for cooperating with the scraping mechanism, brushing mechanism and pressing mechanism to realize anti-blocking cleaning operation and compaction operation of wood chips and dust particles.

[0013] Through this arrangement, when the vertical rotating rod rotates, it drives the scraping rod and the scraping plate to rotate synchronously, thereby facilitating automatic scraping and cleaning of stubborn dust particles adhered to the coarse filter screen. The cleaning force is strong and the effect is sufficient, which effectively improves the filtration efficiency of the coarse filter screen, facilitates the wood chips and dust to be fully discharged into the receiving barrel below for collection, and improves the dust removal efficiency.

[0014] As a preferred embodiment of the present invention, a dust guide port is provided on the partition, and the fine filter is slidably plugged into the dust guide port.

The processing effect is sufficient, the processing steps for sawdust are reduced, and the collection and processing of dust are convenient, thereby effectively improving work efficiency.

[0022] As a preferred embodiment of the present invention, a guide groove is provided at the bottom of the push plate, a guide rail is fixedly connected to the inner bottom of the material receiving barrel, and the guide groove slides along the guide rail.

[0023] This arrangement facilitates guiding the moving direction of the push plate, so that the push plate has high stability when moving.

At this time, the fine filter will slide along the slide rod through the slide plate and elastically squeeze the spring. When the shift block passes over the fine filter, the fine filter will elastically reset, and then it is convenient to drive the fine filter to slide and vibrate left and right on the dust guide port, so as to shake off the dust particles adhered to it, and the cleaning effect is sufficient to prevent blocking, which further improves the use efficiency of the fine filter.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: wood chip dust is sucked into the interior of the dust removal box through the dust inlet pipe, and the first-level dust removal is achieved through spraying dust reduction and filtering through a coarse filter, and then the second-level dust removal is achieved through filtering through a fine filter, and finally the third-level dust removal is achieved through filtering through a glass fiber filter.

[0034] By adopting the above scheme, the dust inlet pipe 104 is connected to the dust exhaust end of the wood processing machine tool. By starting the dust suction fan, the wood chips and dust can be sucked into the dust removal box 1 for dust removal. Starting the motor 402 can drive the horizontal rotation rod 4 to rotate, which is convenient for cooperating with the scraping mechanism, the brushing mechanism and the pressing mechanism to realize anti-blocking cleaning operation and compaction operation of wood chips and dust particles.

[0035] Specifically, a water guide groove 503 is provided at the top of the vertical rotation rod 5, and spray pipes 501 are fixedly connected to both sides of the water guide groove 503. A nozzle 502 is fixedly connected to the bottom of the spray pipe 501. A water guide pipe 6 is connected to the water guide groove 503 through a bearing sleeve.

A slave bevel gear 507 is fixedly sleeved on the bottom of the vertical rotation rod 5, and the slave bevel gear 507 is meshingly connected to the main bevel gear 404.

[0036] By adopting the above scheme, it is convenient to install the water pipe 601 on the vertical rotating rod 5, and connect it to the external water pump through the water pipe 601, so that the spray pipe 501 and the nozzle 502 can spray water mist to the dust inside the dust removal box 1 to reduce dust, and the dust removal effect is good and easy to use. In addition, through the cooperation of the slave bevel gear 507 and the main bevel gear 404, when the horizontal rotating rod 4 rotates, it can drive the vertical rotating rod 5 to rotate synchronously, and then it is convenient to drive the spray pipe 501 to perform rotational spraying operation, so as to realize multi-directional dust reduction work, which is beneficial to improve the dust reduction efficiency.

[0037] Specifically, a scraping rod 505 is sleeved and fixed on the vertical rotating rods 5 corresponding to the upper and lower surfaces of the coarse filter 102 , and a scraping plate 506 is fixedly connected to the inner side of the scraping rod 505 , and the scraping plate 506 fits the coarse filter 102 .

[0038] By adopting the above scheme, when the vertical rotating rod 5 rotates, it drives the scraping rod 505 and the scraping plate 506 to rotate synchronously, thereby facilitating automatic scraping and cleaning of the stubborn dust particles adhering to the coarse filter screen 102. The cleaning force is strong and the effect is sufficient, which effectively improves the filtering efficiency of the coarse filter screen 102, facilitates the wood chips and dust to be fully discharged into the receiving barrel 2 below for collection, and improves the dust removal efficiency.

[0039] Specifically, a dust guide port 106 is provided on the partition plate 101 , and the fine filter 7 is slidably plugged into the dust guide port 106 .

[0040] The above scheme makes it easy to install the fine filter 7. After the dust reduction by spraying water mist and the primary dust removal by the coarse filter 102, some of the tiny dust and particles will enter the dust guide port 106 and undergo secondary filtration and dust removal through the fine filter 7, thereby enhancing the dust removal effect.

[0041] Specifically, a brush rod 801 is fixedly connected to the transverse rod 4, the middle part of the brush plate 8 is fixedly connected to the brush rod 801, and evenly distributed bristles 802 are fixedly connected to the surface of the brush plate 8. The brush plate 8 and the glass fiber filter 103 are both arranged in a matching arc-shaped structure, the bristles 802 fit tightly against the glass fiber filter 103, and a toothed disc 803 is fixedly sleeved on the end of the brush plate 8.

The push plate 301 that slides left and right can push the sawdust and press it against the inner walls of the first end cover 201 and the second end cover 202, thereby realizing the compaction of the sawdust. When the compacted material needs to be taken out, the first end cover 201 or the second end cover 202 is opened to push out the compacted sawdust. The processing effect is sufficient, the processing steps of the sawdust are reduced, the collection and processing of the dust are convenient, and the work efficiency is effectively improved.
