Description
Technical Field
[0001] This utility model belongs to the technical field of parts processing equipment, and specifically relates to a spraying device for parts processing. Background Technology
[0002] In the parts processing flow, after the parts have completed their machining steps, a spraying device is used to spray liquid onto their surface. This liquid serves a wide range of purposes. On one hand, it can promptly remove heat generated during machining due to friction between the cutting tool and the parts, thus cooling the parts and preventing thermal deformation or changes in metallographic structure that could affect their performance and precision. On the other hand, it can effectively wash away metal shavings, oil, dust, and other impurities that adhered to the parts' surface during machining, cleaning the surface and laying a good foundation for subsequent processes, thereby contributing to the production of high-quality parts.
[0003] However, in practical applications, the liquids used in spraying devices, such as cutting fluids, cleaning fluids, and rust inhibitors, will release harmful gases after being sprayed onto the parts. For example, cutting fluids containing sulfur and chlorine additives may release hydrogen sulfide and hydrogen chloride; organic solvent-based cleaning fluids will release volatile organic compounds such as benzene and toluene. Workers who are exposed to an environment full of these harmful gases for a long time will have their health threatened and may develop diseases. To address these issues, we have proposed a spraying device for parts processing. Utility Model Content
[0004] The purpose of this invention is to provide a spraying device for parts processing to solve the problems existing in the background art.

[0007] The filter assembly includes two mounting plates. The upper end of the spray box has several heat dissipation grooves communicating with the spray chamber. The front end of the spray box has two longitudinally arranged mounting grooves, which are vertically connected to each of the heat dissipation grooves. The two grooves form a through structure at their vertical intersection. The two mounting plates are slidably sealed inside the two mounting grooves. The upper end of each mounting plate has a groove, and an activated carbon plate is sealed inside each groove. The lower end of each mounting plate has several air vents communicating with the groove. The front end of each mounting plate has a handle. The front end of the spray box has a locking assembly located between the two mounting plates.
[0008] Further specifying, the locking assembly includes a locking strip, a rotating shaft is damped and rotatably mounted at the front end of the spray box, the locking strip is fixed to the outside of the rotating shaft, and both sides of the locking strip abut against the front ends of the two mounting plates respectively.

[0014] The beneficial effects of this utility model are:
[0015] 1. The oven supplies hot air to the spray chamber through two air supply pipes. While drying the parts, the hot air drives the airflow in the spray chamber. Then, this air containing harmful gases is discharged through the heat dissipation channel. When discharged, the gas first enters the mounting plate. Two activated carbon plates arranged vertically inside the mounting plate perform multiple filtrations on the harmful gases, ultimately achieving clean discharge. This not only prevents environmental pollution and protects the staff, but also makes it convenient for the staff to replace the activated carbon plates.

Detailed Implementation
[0027] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0028] Example 1:
[0029] like Figures 1-4 As shown, a spraying device for parts processing includes a spraying box 100. A partition 101 is fixed in the middle of the inner wall of the spraying box 100. The upper side of the partition 101 is configured as a spraying chamber 102, and the lower side of the partition 101 is configured as a liquid storage chamber 103. A through groove 104 is opened in the middle of the upper end of the partition 101. A metal mesh 105 is provided on the inner wall of the through groove 104. A spraying assembly is provided at the rear end of the spraying box 100. An oven 106 is provided at the left end of the spraying box 100. Two air supply pipes 107 are connected between the oven 106 and the spraying chamber 102. A filter assembly is provided on the upper side inside the spraying box 100.
[0030] The filter assembly includes two mounting plates 200. The upper end of the spray box 100 is provided with several heat dissipation grooves 201 that communicate with the spray chamber 102. The front end of the spray box 100 is provided with two longitudinally arranged mounting grooves 202, and the two mounting grooves 202 are vertically connected to each heat dissipation groove 201. The two grooves form a through structure at the vertical intersection. The two mounting plates 200 are slidably sealed inside the two mounting grooves 202. The upper end of each of the two mounting plates 200 is provided with a groove 203, and an activated carbon plate 204 is sealed inside each of the two grooves 203. The lower end of each of the two mounting plates 200 is provided with several air vents 205 that communicate with the grooves 203. The front end of each of the two mounting plates 200 is provided with a handle 206. The front end of the spray box 100 is provided with a locking component, and the locking component is located between the two mounting plates 200.
[0031] The partition 101 divides the interior of the spray box 100 into upper and lower sections for different functions; the metal mesh 105 facilitates the placement of parts and also allows the sprayed liquid to drip down, preventing the liquid from accumulating on the partition 101 and making it difficult for subsequent cleaning; the through groove 104 limits the range of parts placement and the spraying range, allowing for more accurate spraying of parts; the spray chamber 102 can hold parts, which are then sprayed by the spraying assembly; the liquid storage chamber 103 can store the liquid required for spraying; the drying oven 106 can draw in and heat outside air, and the heated air is delivered to the spray chamber 102 through two air supply pipes 107, which not only dries the parts but also drives airflow, carrying away harmful gases inside the spray chamber 102, and finally exhausting them from the heat dissipation slots 201;
[0032] The heat dissipation groove 201 facilitates the discharge of gas inside the spray chamber 102; the mounting groove 202 is vertically connected to the heat dissipation groove 201, so that when gas flows through the heat dissipation groove 201, it passes through the interior of the mounting plate 200; the venting groove 205 is connected to the recess 203, facilitating the flow of air through the mounting plate 200; the activated carbon plate 204 can filter the gas inside the spray chamber 102, thereby obtaining clean air; the locking component can restrict the mounting plate 200 to prevent the mounting plate 200 from moving out of the mounting groove 202, causing gas leakage inside the spray chamber 102.
[0033] After spraying is completed: start the oven 106, the oven 106 absorbs and heats the outside air, and the heated air is delivered to the inside of the spray chamber 102 through two air supply pipes 107, thereby drying the parts. At the same time, the hot air will also drive the air inside the spray chamber 102 to be discharged from each heat dissipation slot 201.
[0034] When air passes through the interior of each heat dissipation slot 201, it will first enter the interior of the mounting plate 200. In this way, the activated carbon plate 204 inside the mounting plate 200 can filter the harmful gases in the air, so that clean air can be discharged, thereby preventing environmental pollution and preventing harm to the staff.
[0035] Among them, the two air supply pipes 107 can increase the amount of hot air transported and improve drying efficiency;
[0036] The two activated carbon plates 204 can perform multiple filtrations of the air, improving the filtration efficiency of the exhaust air. At the same time, the two activated carbon plates 204 are arranged one above the other, so that the activated carbon plates 204 can be replaced without stopping the use of the spray device.
[0037] In this embodiment, after the spraying is completed, the drying oven is started. The drying oven absorbs and heats the outside air. The heated air is then transported to the spraying chamber through two air supply pipes to dry the parts. At the same time, the air in the spraying chamber is discharged from the heat dissipation tank. When the air passes through the heat dissipation tank, it first enters the mounting plate, where the activated carbon plate in the mounting plate filters out harmful gases, achieving clean emission and avoiding environmental pollution and harm to workers.
[0038] Example 2:
[0039] like Figures 1-6 As shown, based on Embodiment 1, other components of a spray device for parts processing are further described. The locking assembly includes a locking strip 300. A rotating shaft 301 is mounted on the front end of the spray box 100 with damping rotation. The locking strip 300 is fixed to the outside of the rotating shaft 301, and the two sides of the locking strip 300 abut against the front ends of two mounting plates 200 respectively.
[0040] Two limiting rods 302 are symmetrically fixed at the lower ends of the two mounting plates 200, and the two limiting rods 302 are slidably disposed inside either heat dissipation groove 201.
[0041] The spray assembly includes several nozzles 303. A spray pump 304 is placed at the rear end of the spray box 100. A first liquid delivery pipe 305 is connected between the inlet of the spray pump 304 and the liquid storage chamber 103. A spray plate 306 is provided on the inner wall of the spray box 100. A second liquid delivery pipe 307 is connected between the outlet of the spray pump 304 and the spray plate 306. Each nozzle 303 is evenly distributed longitudinally on the outside of the spray plate 306.
[0042] A baffle 400 is hinged at the opening where the gas pipe 107 extends into the spray chamber 102.
[0043] An inclined filter plate 401 is fixed to the rear wall of the spray box 100, and the filter plate 401 is located inside the liquid storage chamber 103. A waste box 402 is provided between the front end of the filter plate 401 and the front wall of the spray box 100. A cover plate 403 communicating with the waste box 402 is provided at the front end of the spray box 100.
[0044] The spray box 100 has an inlet 404 at the front end that communicates with the liquid storage chamber 103, and an outlet 405 at the rear end that communicates with the liquid storage chamber 103.
[0045] In this embodiment, when the clip 300 is in a vertical state: the upper and lower sides of the rear end of the clip 300 will abut against the front ends of the two mounting plates 200, which can prevent the mounting plates 200 from sliding out of the mounting groove 202, thereby causing gas leakage inside the spray chamber 102, which in turn pollutes the environment and affects human health.
[0046] When the clip 300 is in a horizontal position: the clip 300 is parallel to the two mounting plates 200, so that the operator can remove the mounting plates 200 from the mounting groove 202 and replace the activated carbon plate 204 so that the gas inside the spray chamber 102 can be filtered in the future.
[0047] The rotating shaft 301 is damped and rotates with the spray box 100, so after rotating the rotating shaft 301, the clamping strip 300 can maintain its current state without the influence of other external forces.
[0048] The limiting rod 302 is located inside the heat dissipation groove 201, which restricts the movement range of the limiting rod 302, so that the limiting rod 302 can only slide inside the heat dissipation groove 201. This indirectly restricts the movement distance of the mounting plate 200, thereby preventing the mounting plate 200 from directly detaching from the mounting groove 202.
[0049] When the mounting plate 200 is pulled out of the mounting groove 202, until the limiting rod 302 abuts against the front wall of the heat dissipation groove 201, the rear end of the mounting plate 200 can seal the opening of the mounting groove 202, so that the gas inside the spray chamber 102 will not leak when the activated carbon plate 204 is replaced.
[0050] When the spray pump 304 is started, the spray pump 304 will draw liquid from the inside of the liquid storage chamber 103 through the first liquid delivery pipe 305, and then deliver the liquid to the inside of the spray plate 306 through the second liquid delivery pipe 307. Finally, the liquid is sprayed onto the surface of the part by each nozzle 303. This not only cools the part, but also removes impurities from the surface of the part.
[0051] Initially: The baffle 400 blocks the opening of the gas supply pipe 107, which can prevent the sprayed liquid from entering the oven 106 through the gas supply pipe 107 during spraying, thereby damaging the oven 106;
[0052] When hot air is delivered into the spray chamber 102 through the air supply pipe 107, the ejected gas will first lift the baffle 400, thus drying the parts.
[0053] During spraying, excess liquid will drip down through the metal mesh 105. When this liquid drips onto the filter plate 401, the filter plate 401 will filter the liquid and separate the impurities in the liquid. The filtered liquid will be stored inside the liquid storage chamber 103 for later use.
[0054] Among them, the surface of the inclined filter plate 401 will retain the filtered impurities, and the subsequent dripping liquid will gradually push these impurities forward until the iron filings, dust and impurities enter the waste box 402 for storage.
[0055] Staff can easily clean the impurities inside the waste box 402 by opening the cover 403.
[0056] Workers can fill the liquid storage chamber 103 with the liquid inlet 404 for storage, which will facilitate subsequent spraying of the parts. When the liquid in the storage chamber 103 has been used for too long, workers can drain the liquid from the storage chamber 103 through the liquid outlet 405. This allows the liquid to be replaced and prevents it from affecting the quality of the parts after being sprayed onto them.
[0057] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
