Description

Technical Field

[0001] The present invention relates to the technical field of spraying equipment, and more specifically, to a paint spraying cabinet with paint scraping and recycling functions. Background Art

[0002] Paint is a chemical mixture coating that can firmly cover the surface of an object, serving for protection, decoration, marking, and other special purposes. Spraying paint is to disperse it into uniform and fine droplets through a spray gun or a disc atomizer by means of pressure or centrifugal force, and apply it to the surface of the object to be painted, so that each object to be sprayed obtains a coating. The paint spraying cabinet is mainly an environmental protection equipment for treating paint spraying waste gas in the paint spraying production line workshops of various industries, so that the odor and a small amount of paint mist generated during paint spraying are discharged outdoors after being recycled and treated in the cabinet body, thereby achieving the purposes of purifying the working environment and protecting the health of operators.

[0003] At present, a large amount of impurity gas is generated after paint spraying. If it is not removed in time, it will not only pollute the environment, but also affect the paint spraying quality and the health of workers, which does not conform to the current environmental protection concept. At the same time, the paint droplets contained in the impurity gas are directly discarded without being recycled and reused, resulting in waste and reducing the utilization rate of paint.

[0004] Among them, the waste gas such as paint mist generated during the paint spraying process is characterized by a large air volume, low-concentration volatile organic compounds, and high-concentration paint mist dust. Therefore, the existing recycling and treatment technologies have the following disadvantages when applied to such paint spraying and paint mist: First, the high-concentration paint mist of paint spraying is sticky, easy to block the filter, and it is difficult to remove and recycle the blockage, increasing the cost; Second, it is difficult to fully recycle the paint spraying, and the recycling is difficult. Summary of the Invention

[0005] The present invention discloses a paint spraying cabinet with paint scraping and recycling functions, aiming to improve the problem that it is difficult to fully recycle and clean the paint spraying in the existing paint spraying cabinet.

[0006] The present invention adopts the following solutions:

Among them, a recycling component is arranged in the recycling space, and the recycling component includes an adsorbent placed on the path of the exhaust air channel and an oil scraping member arranged in cooperation with the adsorbent; the adsorbent has a plurality of partition plates arranged at intervals, and the partition plates are provided with through holes to allow the paint spraying entering the cabinet body to adhere to the surfaces of different partition plates through the through holes; the oil scraping member and the adsorbent can move relative to each other, so that the paint spraying adhering to the surface of the partition plate is scraped off outside the adsorbent, and the paint spraying is centrally recycled and treated in the cabinet body.

[0008] As a further improvement, the recovery space includes a first recovery area and a second recovery area arranged in sequence along the path of the paint spray entering the exhaust passage, and the two recovery areas communicate with each other; the bottom of the cabinet body is arranged substantially obliquely, and recovery ports for collecting the paint spray are configured at the lower positions of the respective bottoms of different recovery areas; the partition plate is arranged in the cabinet body to divide the recovery space into two different recovery areas.

[0009] As a further improvement, the inlet is opened on the side close to the user, the outlet is opened above the cabinet body on the side far from the inlet, and the partition plate is arranged vertically and at intervals in the cabinet body.

[0010] As a further improvement, the partition plate is in the shape of a plate body and at least three partition plates are provided. The through holes formed in each partition plate are arranged in a staggered manner so that the attachment surface where the partition plate on the side facing the paint spray entry path can fully adsorb the paint spray. And, the oil scraping member is fitted on the adsorption surface to scrape off the paint spray when any one of the oil scraping member or the adsorption member moves relatively.

[0011] As a further improvement, the oil scraping member moves relative to the adsorption member through a driving member and a transmission member configured on the cabinet body. And, the output shaft of the driving member is linked with the transmission member to transmit power to the oil scraping member via the transmission member, so that the oil scraping member can slide up and down relative to the partition plate and always keep in contact with the adsorption surface.

[0012] As a further improvement, the oil scraping member is attached to the adsorption surface in a manner of elastic abutment, and the oil scraping member has a blade end, and the blade end elastically abuts at the adsorption surface.

[0013] As a further improvement, the oil scraping member has a receiving cavity capable of accommodating thinner. The receiving cavity is formed by a part of the blade end and can make the thinner in the volume of the receiving cavity moisten the blade end during the oil scraping process to dilute and soften the paint spray at the adsorption surface contacted by the blade end.

[0014] As a further improvement, the receiving cavity is provided with a liquid outlet and a liquid inlet, and an external pump body is used to make the thinner reach a liquid level height in the volume of the receiving cavity to at least moisten the blade end.

[0015] As a further improvement, the partition plate is in the shape of a hollow cylinder, and a plurality of the partition plates are sleeved with each other at intervals; the partition plates can rotate relative to each other under the drive of an external force, the oil scraping member is configured on the side far from the first recovery area, and always elastically abuts against the outer peripheral edge of each partition plate.

[0016] As a further improvement, the oil scraping member always abuts against the outer peripheral edge of the partition plate in the transverse direction, and the vertical length of the blade end of the oil scraping member is the same as the height of the partition plate.

[0017] By adopting the above technical solutions, the following technical effects can be achieved in the present invention:

[0018] For the paint spraying cabinet of the present application, through the recovery assembly configured in the cabinet body, the paint spraying waste gas can be treated, so that the paint mist generated during paint spraying is discharged outdoors after being recovered and treated in the cabinet body.

[0033] Embodiment 1

[0034] Combined Figures 1 to 3 , this embodiment provides a paint spraying recovery cabinet, comprising: a cabinet body 1. The cabinet body 1 has an inlet 2, an outlet 3 and a recovery space disposed between the inlet 2 and the outlet 3. An exhaust passage is formed between the inlet 2 and the outlet 3. Among them, the recovery space includes a first recovery area 4 and a second recovery area 5 arranged in sequence along the path of the paint spraying entering the exhaust passage, and the two recovery areas communicate with each other. The first recovery area 4 is an empty chamber for receiving a part of the paint spraying entering the cabinet body 1 through the inlet 2 for centralized recovery and treatment. The second recovery area 5 is used to recover other parts of the paint spraying entering the recovery area, so that the paint spraying entering the second recovery area 5 to the outlet 3 can be recovered and treated within the second recovery area 5.

[0035] In this embodiment, the recovery space in the cabinet 1 is used to recover and process the paint spray that enters the cabinet 1 through the inlet 2. The paint spray is conveyed in the exhaust passage until the treated waste gas is discharged from the outlet 3 to the outside of the cabinet 1, realizing the recovery and treatment of the paint spray in the cabinet 1. Among them, a first recovery area 4 and a second recovery area 5 are correspondingly arranged along the path of the paint spray entering the cabinet 1, so as to recover the paint spray in the two through recovery areas respectively. A part of the paint spray entering the cabinet 1 can be centrally recovered and treated by the first recovery area 4 with a vacant chamber, and the other part of the paint spray enters the second recovery area 5 to be correspondingly recovered in the second recovery area 5, realizing multi-mode paint spray recovery with better treatment effect. Moreover, in the first recovery area 4, a part of the paint spray directly falls to the bottom of the first recovery area 4 due to its own gravity or spraying speed, etc., for the initial screening of the paint spray to be recovered and treated, sinking the paint spray particles to the first recovery area 4 for recycling, making the paint spray entering the second recovery area 5 purer and easier to recover and treat, so as to specifically recover different paint sprays with remarkable effect.

[0036] In one implementation manner, the first recovery area 4 is formed by enclosing the outer shell of part of the cabinet 1, and the second recovery area 5 includes a recovery component 6 disposed in the cabinet 1 and located near the outlet 3 in the second recovery area 5. The vacant chamber of the first recovery area 4 is enclosed by the outer shell of the cabinet 1 on the side close to the inlet 2, so that a part of the paint spray entering the cabinet 1 can be centrally recovered at the bottom of the cabinet 1 in the form of free fall in the vacant chamber to facilitate the initial screening and recovery of gravity objects such as paint spray particles. An exhaust fan is equipped at the outlet 3 so that the paint spray entering from the inlet 2 can be conveyed along the exhaust passage under the drive of the exhaust fan. The remaining paint spray / paint mist enters the second recovery area 5 from the first recovery area 4, and the recovery component 6 configured in the second recovery area 5 is used to recover and treat the paint spray. The specific configuration of the recovery component 6 in the second recovery area 5 will be further elaborated in the following Embodiment 2.

[0037] In a preferred implementation manner, the bottom of the cabinet 1 is generally inclined, and recovery ports 7 for collecting the paint spray are arranged at the low positions of the respective bottoms of different recovery areas. Thus, the separate recovery of the paint spray by different recovery areas is realized, which is beneficial to classifying the recovered paint spray with different concentrations. And the recovery ports 7 provided at the low positions can realize the centralized convergence of the paint spray collected by each recovery area.

[0038] In one embodiment, each recovery port 7 is correspondingly provided with a storage barrel 8 for receiving the paint flowing into the recovery port 7. A filtering component 9 is arranged between the recovery port 7 at the second recovery area 5 and the storage barrel 8 opposite thereto. It should be noted that the spray paint entering the second recovery area 5 is preliminarily screened and filtered through the first recovery area 4 to obtain relatively light spray paint, making the spray paint recovery in the second recovery area 5 cleaner. Moreover, by configuring a filtering component 9 at the recovery port 7 of the second recovery area 5, the spray paint recovery is further filtered again to obtain recovered paint that can meet the daily spray paint requirements, which is economical and environmentally friendly. Specifically, the filtering component 9 is a filter screen horizontally placed between the storage barrel 8 and the recovery port 7 for filtering the paint delivered from the recovery port 7 to the storage barrel 8.

[0039] Please refer to Figure 6 and Figure 7 , in other embodiments, preferably, the cabinet body 1 at least includes a first main cabinet 10 and a second main cabinet 11 that can be pushed and pulled to slide in a mating manner. The two main cabinets are nested and move horizontally through a sliding component (not shown in the figure), so that one of the first main cabinet 10 and the second main cabinet 11 can move relative to the other under the push of an external force to switch between the storage state and the working state. Among them, the first recovery area 4 is located in the first main cabinet 10, and the second recovery area 5 is correspondingly located in the second main cabinet 11. By dividing the cabinet body 1 into a first main cabinet 10 and a second main cabinet 11 that can slide in a mating manner, and configuring a sliding mechanism between the main cabinets so that one main cabinet can move relative to the other under the push of an external force, when it is necessary to carry and transfer or in the non-working state, the main cabinets are pushed to the nested storage state to reduce the floor area and make effective use of the space. In the working state, the main cabinets are pulled to the separated working state, thereby forming the accommodation space of the entire cabinet body 1, which is convenient to operate and highly practical.

[0040] It should be mentioned that the sliding component is a sliding mechanism such as a pulley and a slide rail, which can meet the requirement that the first cabinet body 1 nests and moves along the direction of the second cabinet body 1 in cooperation with the sliding mechanism. Moreover, when switching to the storage state, there is no interference between the first recovery area 4 and the second recovery area 5, so as to facilitate the recovery and treatment of spray paint when switching to the working state.

[0041] Embodiment 2

[0042] The spray paint cabinet provided by Embodiment 2 of the present invention has the same implementation principle and technical effects as those of the above embodiments. For a brief description, for the parts not mentioned in this Embodiment 2, reference can be made to the corresponding content in the above embodiments.

[0043] Combined with Figures 1 to 7, this embodiment provides a painting cabinet with paint scraping and recycling functions, including: a cabinet body 1. The cabinet body 1 has an inlet 2, an outlet 3, and a recycling space configured between the inlet 2 and the outlet 3. An exhaust air passage is formed between the inlet 2 and the outlet 3. Among them, the recycling space is configured with a recycling component 6, and the recycling component 6 includes an adsorbent 12 placed on the exhaust air passage path and a scraping member 13 arranged in cooperation with the adsorbent 12. The adsorbent 12 has a plurality of spaced-apart partitions 14, and the partitions 14 are provided with through holes (not shown in the figure) to allow the paint sprayed into the cabinet body 1 to adhere to the surfaces of different partitions 14 via the through holes. The scraping member 13 and the adsorbent 12 can move relative to each other, so that the paint adhering to the surface of the partition 14 is scraped off outside the adsorbent 12, and the paint is centrally recycled and processed in the cabinet body 1.

[0044] In this embodiment, through the recycling component 6 configured in the cabinet body 1, the paint waste gas can be treated, so that the paint mist generated during painting is discharged outdoors after being recycled and processed in the cabinet body 1. Moreover, different partitions 14 of the adsorbent 12 are provided with through holes, so that the paint sprayed into the cabinet body 1 can fully adhere to the surfaces of the respective partitions 14, and the scraping member 13 and the adsorbent 12 can move relative to each other to scrape off the adhered paint, and the paint is centrally recycled and processed in the cabinet body 1. By recycling and processing the paint in the way of scraping oil, the adsorption and recycling of the paint by the adsorbent 12 are improved, and it is beneficial to the cleaning and recycling of viscous substances such as paint.

[0045] It should be mentioned that, in this embodiment, the partition 14 is blocked in the cabinet body 1 to divide the recycling space into two different recycling areas. Thus, it is convenient for the centralized recycling and processing of paint in different recycling areas. Further, the inlet 2 is opened on the side close to the user, the outlet 3 is opened above the cabinet body 1 on the side far from the inlet 2, and the partition 14 is spaced and vertically arranged in the cabinet body 1. Among them, the adsorbent 12 can make the paint sprayed into the second recycling area 5 adhere to it, and guide the adsorbed paint to the recycling port 7 located at the bottom.

[0046] In one embodiment, there are at least three partitions 14, and the through holes opened in the respective partitions 14 are arranged in a staggered manner with each other, so that the attachment surface of the partition 14 on the side facing the paint spraying path can fully adsorb the paint. Moreover, the scraping member 13 is fitted and arranged on the adsorption surface to scrape off the paint when either the scraping member 13 or the adsorbent 12 moves relative to each other. Thus, the viscous paint is scraped off by sliding, which is beneficial to the partition 14 to adsorb the paint again, and the recycling of the paint is more efficient and fast. The through holes penetrate horizontally through the plate body of the partition 14, so that the adsorption surface at the surface of the partition 14 on the side close to the first recycling area 4 can face the incoming paint, which is beneficial to the adsorption and recycling of the paint material.

[0047] Please refer to Figures 1 to 5, in one of the embodiments, the partition 14 is preferably in the shape of a plate body. Each partition 14 divides the recovery area in a vertically arranged manner and is arranged substantially perpendicular to the direction in which the paint enters. Correspondingly, the oil scraping member 13 moves relative to the adsorbing member 12 through the driving member 15 and the transmission member 16 arranged on the cabinet body 1. Moreover, the output shaft of the driving member 15 is linked with the transmission member 16 to transmit power to the oil scraping member 13 via the transmission member 16, so that the oil scraping member 13 can slide up and down relative to the partition 14 and always keep in contact with the adsorption surface. It should be noted that the driving member 15 is preferably a stepping motor, and the transmission member 16 can be selected as a chain drive or a gear drive, etc. to drive the oil scraping member 13 to move up and down relative to the partition 14, which will not be elaborated here.

[0048] Furthermore, the oil scraping member 13 is in contact with the adsorption surface in a manner of elastic abutment, and the oil scraping member 13 has a blade end 17, and the blade end 17 elastically abuts at the adsorption surface. Preferably, through the pressing and abutting of an elastic member (not shown in the figure) correspondingly arranged in the cabinet body 1, the blade end 17 of the oil scraping member 13 always keeps elastically abutting on one side of the adsorption surface, so that the paint attached to the partition 14 can be scraped off by the blade end 17 during the up and down sliding process.

[0049] Among them, preferably, the oil scraping member 13 has a receiving cavity 18 capable of accommodating thinner. The receiving cavity 18 is formed by a part of the blade end 17, and the thinner in the volume of the receiving cavity 18 can wet the blade end 17 during the oil scraping process to dilute and soften the paint at the adsorption surface contacted by the blade end 17. Particularly, the blade end 17 is recessed downward to form the receiving cavity 18, and the blade end 17 is arranged substantially inclined upward, so that the opening of its receiving cavity 18 faces upward, which is beneficial to storing the thinner, and when the oil scraping member 13 moves up and down, the blade end 17 can be wetted and part of the thinner can flow to the contact position between the adsorption surface and the blade end 17 along with the movement, further diluting and softening the paint, which is convenient for the recovery treatment of the paint.

[0050] It should be noted that a liquid outlet 19 and a liquid inlet 20 are provided on the receiving cavity 18, and the thinner can be made to reach a liquid level height in the volume of the receiving cavity 18 by an external pump body (not shown in the figure) so as to at least wet the blade end 17. The external pump body forms a conveying loop with the liquid outlet 19, the liquid inlet 20 and the thinner deposited in the receiving cavity 18 through a circulating pipeline to regulate the liquid level height at the receiving cavity 18 and can conveniently update the thinner in the receiving cavity 18 to prevent too much paint from dissolving in the thinner and thus weakening the effect of the thinner. Particularly, the liquid inlet 20 is substantially located at the bottom of the receiving cavity 18 of the blade end 17, the liquid outlet 19 is arranged higher than the liquid inlet 20 on one side of the blade end 17, and the liquid inlet rate of the liquid inlet 20 is greater than the liquid outlet rate of the liquid outlet 19 to ensure the liquid level height of the receiving cavity 18.

[0051] Please refer toFigure 6 and Figure 7 , in another embodiment, the partition 14 is in the shape of a hollow cylinder, and a plurality of partitions 14 are sleeved with each other at intervals, so that the cylindrical partitions 14 are stacked and nested with each other. Among them, the partition 14 can rotate relative to each other under the drive of an external force. The oil scraping member 13 is arranged on the side away from the first recovery area 4 and always elastically abuts against the outer peripheral edge of each partition 14. In particular, the partitions 14 are movably connected by axial rotation, so that some of the partitions 14 on the side away from the first recovery area 4 can move to the side close to the first recovery area 4. The cylindrical partition 14 increases the attachment area of the adsorbing member 12, and through the axial rotation method, the outer peripheral edge of the partition 14 can be rotated to face the paint spraying inlet side, so as to fully adsorb and recover the paint spraying.

[0052] In this embodiment, the oil scraping member 13 always abuts against the outer peripheral edge of the partition 14 in the transverse direction, and the vertical length of the blade end 17 of the oil scraping member 13 is the same as the height of the partition 14. For the relatively axially rotating partition 14, under the elastic abutment of the oil scraping member 13 arranged on one side thereof, and the oil scraping member 13 is arranged to be able to completely scrape the entire outer peripheral edge of the partition 14, so as to scrape off the paint spraying quickly and efficiently, and then guide it to be recovered to the corresponding recovery port 7.

[0053] It should be noted that other features not mentioned in Embodiment 2 can be the same as those in the above embodiments, and the deformable embodiments that can be adopted and their beneficial effects can also be the same as those in the above embodiments, so they will not be repeated.

[0054] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention.
