Description

Technical Field

[0001] The utility model relates to the technical field of aluminum part grinding dust treatment, in particular to aluminum part grinding dust wet treatment equipment. Background Art

[0002] A large amount of dust is generated during the grinding process of aluminum parts, which needs to be centrally treated. There are many ways to treat it, including wet treatment.

[0003] The wet treatment process is to collect the dust through the air collection hood and the collection air duct. The Venturi wet dust collector uses the dust removal fan to suck the dust-containing air into the air inlet of the wet dust removal system. The air containing fine particles enters the formal water mist dust removal for subsequent treatment. After the water mist and dust are fully mixed, the dust-containing sewage flows into the filter water tank and forms sludge through sedimentation. The sludge is scraped out to the mud loading cart through the sludge scraping system.

[0004] In the dust treatment process of the above-mentioned treatment device, clean water and dust are mixed to form sewage, which is not convenient for recycling. Therefore, a large amount of clean water is consumed, resulting in a waste of resources. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the utility model provides a wet treatment device for aluminum polishing dust, which can effectively solve the problems raised in the background technology.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] The utility model provides a wet treatment device for aluminum polishing dust, comprising a treatment tank, a feed pipe inserted through the treatment tank, an exhaust pipe opened through the inner cavity of the outer tank wall of the treatment tank, a horn pipe connected to the bottom of the treatment tank, a filter embedded in the other output end of the horn pipe, a backwash component comprising a backwash pipe installed at one end of the horn pipe, a backwash pump installed on the backwash pipe, the output end of the backwash pump being connected to a single nozzle arranged in the backwash pipe, a circulating flushing component comprising a circulating water pump installed at the other end of the backwash pipe, and an annular nozzle installed on the outer tank wall of the treatment tank, the output ends of the annular nozzles being all arranged in the treatment tank and distributed in an annular array, and the annular nozzles being connected to the output end of the circulating water pump.

[0008] Furthermore, a first mounting flange is installed at one end of the feed pipe away from the processing tank, and a second mounting flange is installed at one end of the exhaust pipe away from the processing tank.

[0009] Furthermore, a sedimentation cylinder is installed between the processing tank and the horn tube, and a plurality of sedimentation rings distributed in a concentric circle are arranged in the sedimentation cylinder, and a plurality of fixing bars are installed between two adjacent sedimentation rings.

[0010] Furthermore, a solenoid valve is installed at one of the output ends of the sheep horn tube, and a second solenoid valve is provided between the input end of the sheep horn tube and the sedimentation cylinder.

[0011] Furthermore, a water pipe is connected between the output end of the backwash pump and the single nozzle, and the single nozzle is located opposite to the filter.

[0012] Furthermore, the input end of the circulating water pump is connected to the inner cavity of the backwash pipe, and a circulating pipe is connected between the output end of the circulating water pump and the annular nozzle.

[0013] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects:

[0014] 1. Dust and clean water are mixed. A circulating water pump for extracting sewage is installed at the bottom of the treatment tank. After the sewage is filtered and purified by the filter to form clean water, it is extracted by the circulating water pump and transported to the annular nozzle formed in the treatment tank. The annular nozzle sprays to form an annular water curtain to spray the dust in the treatment tank, thus forming a complete spray flushing system, which has the effect of saving water resources;

[0015] 2. In order to avoid serious clogging on the filter surface, which makes it difficult for the circulating water pump to extract clean water, a backwash component is installed between the circulating water pump and the filter. The filter is flushed from the inside out through the backwash nozzle to ensure that the sediment intercepted by the filter is sent out from the other end of the sheep horn tube;

[0016] 3. In order to ensure that the dust can be continuously flushed during the backwashing stage of the filter, a solenoid valve is installed between the sedimentation cylinder and the sheep horn tube. The discharge channel is temporarily closed by the solenoid valve, so that the sludge backwashed from the filter is uniformly sent out from the other end of the sheep horn tube, which is easy to use.

[0028] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] Example 1

[0031] Reference Figure 1-4, which is the first embodiment of the present utility model, discloses a wet treatment equipment for aluminum grinding dust, including a treatment tank 1, a feed pipe 11 is inserted through the treatment tank 1, an exhaust pipe 13 is opened through the inner cavity of the outer tank wall of the treatment tank 1, a horn pipe 3 is connected to the bottom of the treatment tank 1, and a filter 32 is embedded in the other output end of the horn pipe 3. The filter 32 is formed by overlapping multiple layers of filter meshes with different apertures. The aperture near the single nozzle 43 is smaller, and the aperture away from the single nozzle 43 is larger. The backwashing component includes a backwashing pipe 4 installed at one end of the horn pipe 3, a backwashing pump 41 is installed on the backwashing pipe 4, and the output end of the backwashing pump 41 is connected to the single nozzle 43 arranged in the backwashing pipe 4. The circulating flushing component includes a circulating water pump 5 installed at the other end of the backwashing pipe 4, and also includes an annular nozzle 52 installed on the outer tank wall of the treatment tank 1. The output ends of the annular nozzles 52 are all arranged in the treatment tank 1 and are distributed in an annular array. The annular nozzles 52 are connected to the output end of the circulating water pump 5.

[0032] Example 2

[0033] Reference Figure 1-4 , which is the second embodiment of the present utility model. This embodiment is different from the first embodiment in that: a first mounting flange 12 is installed at one end of the feed pipe 11 away from the processing tank 1, and a second mounting flange 14 is installed at one end of the exhaust pipe 13 away from the processing tank 1 for easy docking. A settling cylinder 2 is installed between the processing tank 1 and the horn tube 3. A plurality of concentrically distributed settling rings 21 are provided in the settling cylinder 2. A plurality of fixing strips 22 are installed between two adjacent settling rings 21. A connecting strip is installed between the outer ring wall of the outermost settling ring 21 and the inner wall of the settling cylinder 2. A first solenoid valve 31 is installed at one of the output ends of the horn tube 3, which controls the discharge of sludge. A second solenoid valve 33 is provided between the input end of the horn tube 3 and the sedimentation cylinder 2, which realizes the continuous flushing of dust and the backwashing of the filter 32 without interference. A water pipe 42 is connected between the output end of the backwash pump 41 and the single nozzle 43, and the single nozzle 43 is opposite to the filter 32. The input end of the circulating water pump 5 is connected to the inner cavity of the backwash pipe 4, and a circulating pipe 51 is connected between the output end of the circulating water pump 5 and the annular nozzle 52.

[0034] The remaining structures are the same as those of Example 1.

[0035] The workflow of this utility model is as follows:

[0036] In the first step, the first solenoid valve 31 is closed and the second solenoid valve 33 is opened. The dust entering from the feed pipe 11 will directly reach the bottom of the treatment tank 1, and the sedimentation cylinder 2 will be completely immersed in clean water. Therefore, some of the dust will be directly immersed in the clean water. As the feed pipe 11 continues to feed, the pressure in the treatment tank 1 increases. Therefore, the dust in the treatment tank 1 should originally be mixed with air and discharged from the exhaust pipe 13.

[0037] In the second step, at the same time, the circulating water pump 5 is started to extract clean water filtered by the filter 32 and supply water to the annular nozzle 52 through the circulating pipe 51. The multiple output ports of the annular nozzle 52 spray water mist to form a water curtain to flush the air and dust to be discharged from the exhaust pipe 13. The air will not be affected by the water curtain and pass through the water curtain and finally be discharged from the exhaust pipe 13. However, the dust forms sludge after meeting water and falls into the sedimentation cylinder 2 due to the increase of gravity. After being settled by the several sedimentation rings 21 in the sedimentation cylinder 2, it is quickly and stably accumulated at the filter 32 of the horn tube 3;

[0038] The third step is to periodically close the second solenoid valve 33, open the first solenoid valve 31, start the backwash pump 41 to flush the filter 32 from the inside out through the single nozzle 43, and the sludge after flushing will only be discharged from the other end of the sheep horn tube 3. During this process, the dust continues to be flushed and cleaned in the treatment tank 1, so the dust treatment efficiency will not be reduced.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
