Description

Technical Field

[0001] This utility model relates to the field of paint spraying cabinet technology, and in particular to a paint spraying cabinet with a filtration device. Background Technology

[0002] A paint booth is a specialized piece of equipment used for painting operations. It is made of color steel plate, galvanized plate, or stainless steel plate. These materials have good sealing and corrosion resistance, which can effectively prevent paint mist leakage and corrosion of the booth during the painting process. The shape and size of the booth vary and are designed according to actual usage needs. During the painting process, air extraction is required. However, simple air extraction can easily draw impurities from the air or the paint spray pipes into the pipes, leading to blockages.

[0003] A search revealed a Chinese patent publication number: CN210876001U, which discloses a paint spraying dust removal device, including a cabinet, with a working plate fixedly installed between the left and right side walls of the cabinet's inner cavity. This paint spraying dust removal device, through the arrangement of the exhaust duct and the exhaust fan, draws in air along the exhaust duct. The exhaust duct connects to the connecting pipe, allowing dust to be drawn in through the connecting pipe and various suction pipes. This ensures dust is absorbed from both sides and the top of the work plate, guaranteeing complete dust collection from all directions. The amplification cylinder increases the absorption range, and the suction net and diversion holes split the intake airflow into multiple streams, increasing suction power. Finally, the dust-laden air is filtered through the filter, and the dust falls into the dust collection box. The odor removal layer then adsorbs odors, purifying the air before it is discharged into the air, achieving comprehensive dust removal. However, in actual use, while the dust collection box handles the extracted dust and dirt, its fixed installation makes cleaning cumbersome, requiring machine shutdown for cleaning, increasing maintenance time and reducing work efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a paint booth with a filter device, which aims to improve the problem that cleaning the inside of the dust collection box in the prior art is cumbersome, requiring machine shutdown for cleaning, increasing replacement and maintenance time, and reducing work efficiency.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a paint spraying cabinet with a filtration device, comprising a cabinet, a baffle plate fixedly connected to the middle of the inner wall of the cabinet, a baffle plate fixedly connected to the rear side of the inner wall of the cabinet, a cabinet door rotatably connected to the front side of the cabinet, a support rod fixedly connected to the inner bottom wall of the cabinet, a magnetic plate fixedly connected to the top of the support rod, a hydraulic rod fixedly connected to the rear side of the cabinet, a concave plate fixedly connected to the right end of the hydraulic rod, a sliding shell fixedly connected to the front side of the concave plate, multiple filter plates fixedly connected at equal intervals to the inner bottom wall of the sliding shell, multiple filter elements placed at equal intervals inside the sliding shell, a limit frame fixedly connected to the upper middle part of the inner wall of the cabinet, an installation ring fixedly connected to the middle of the top wall of the cabinet, a rubber ring fixedly connected to the inner wall of the installation ring, and stabilizing mechanisms provided on both the front and rear sides of the top wall of the cabinet.

[0006] The above technical solution allows the exhaust gas to enter the sliding shell through the limiting frame during extraction. Under the filtration of the filter plate and filter element, the exhaust gas is filtered and adsorbed, thereby improving the filtration effect. At the same time, the sliding shell is driven by the right end of the hydraulic rod to complete the filter element conversion, thus achieving the purpose of replacing the used filter element, avoiding the need for machine shutdown for cleaning, and improving work efficiency.

[0007] As a further description of the above technical solution:

[0008] The stabilizing mechanism includes two upright plates, the bottoms of which are fixedly connected to the front and rear sides of the top wall of the cabinet, respectively. A fixing plate is fixedly connected to one side of each upright plate, and a swing cylinder is fixedly connected to the bottom wall of the fixing plate. A rotating shell is fixedly connected to the top of the swing cylinder, and a connecting rod is fixedly connected to one side of the rotating shell. One end of the connecting rod is rotatably connected to an arc-shaped shell via a torsion spring.

[0009] The above technical solution enables the connecting rod to move the arc-shaped shell as the rotating shell swings, thereby bringing the extraction tube closer to and clamping it. As a result, the arc-shaped shell fits more closely to the outer wall of the extraction tube under the rotational connection of the torsion spring, thus achieving the effect of protecting the outer wall of the extraction tube.

[0010] As a further description of the above technical solution:

[0011] The stabilizing mechanism also includes two rubber pads, with the opposite sides of the two rubber pads fixedly connected to the adjacent sides of the corresponding arc-shaped shell.

[0012] The above technical solution improves the pressure resistance of the outer wall of the extraction tube by connecting the rubber pad.

[0013] As a further description of the above technical solution:

[0014] A control switch is fixedly connected to the left side of the cabinet, and the control switch is electrically connected to the hydraulic rod and the swing cylinder respectively.

[0015] The above technical solution enables the control switch to individually turn the equipment on or off.

[0016] As a further description of the above technical solution:

[0017] Multiple arc grooves are provided on one side of both arc-shaped shells, and the multiple arc grooves are provided at equal intervals.

[0018] The above technical solution improves the toughness of the arc-shaped shell by creating multiple arc grooves.

[0019] As a further description of the above technical solution:

[0020] A handle is fixedly connected to the left side of the cabinet door, and a rubber sleeve is fixedly connected to the middle of the handle. A placement rack is fixedly connected to the right side of the cabinet door and the right side of the sealing ring. A fixed platform is fixedly connected to the bottom front side of the cabinet.

[0021] The above technical solution facilitates the opening of the cabinet door by connecting the handle and the rubber sleeve.

[0022] As a further description of the above technical solution:

[0023] The cabinet has support bases fixedly connected to the four corners of its bottom wall, and support columns are fixedly connected inside the support bases.

[0024] The above technical solution improves the stability of the device during operation by connecting multiple support seats and support columns.

[0025] This utility model has the following beneficial effects:

[0026] 1. In this utility model, with the extraction pipe and the mounting ring installed, the exhaust gas is blocked by baffle one and baffle two, and then the exhaust gas enters the interior of the sliding shell through the limiting frame. Under the filtration of the filter plate and the filter element, the exhaust gas is filtered and adsorbed, which improves the filtration effect of the exhaust gas. At the same time, the sliding shell completes the filter element conversion through sliding, thereby achieving the purpose of replacing the used filter element, avoiding the need for downtime for cleaning, and shortening the replacement and maintenance time.

[0027] 2. In this utility model, the activation of the swing cylinder drives the rotating shell to swing, and then, with the connection of the connecting rod, the arc-shaped shell approaches the extraction tube for clamping. Thus, under the rotational connection of the torsion spring, the arc-shaped shell fits more closely to the outer wall of the extraction tube, thereby achieving the effect of protecting the outer wall of the extraction tube and improving the service life of the extraction tube.

Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a paint spraying cabinet with a filtration device, comprising a cabinet 1. A baffle 3 is fixedly connected to the middle of the inner wall of the cabinet 1, and a baffle 4 is fixedly connected to the rear side of the inner wall of the cabinet 1. The connection between the baffle 3 and the baffle 4 allows for the blocking of exhaust gas. Both the baffle 3 and the baffle 4 are made of cardboard. A cabinet door 5 is rotatably connected to the front side of the cabinet 1. A support rod 6 is fixedly connected to the inner bottom wall of the cabinet 1, and a magnetic plate 7 is fixedly connected to the top of the support rod 6. When the cabinet door 5 is rotated, the interior of the cabinet 1 is opened. The connection between the support rod 6 and the magnetic plate 7 allows for the connection and support of the sample. A hydraulic rod 8 is fixedly connected to the rear side of the cabinet 1, and a concave plate is fixedly connected to the right end of the hydraulic rod 8. 9. A sliding shell 10 is fixedly connected to the front side of the concave plate 9. Multiple filter plates 11 are fixedly connected at equal intervals to the inner bottom wall of the sliding shell 10. Multiple filter elements 12 are placed at equal intervals inside the sliding shell 10. Driven by the hydraulic rod 8, the concave plate 9 drives the sliding shell 10 to slide, thereby the displacement of the sliding shell 10 causes the filter elements 12 inside to switch. A limit frame 13 is fixedly connected to the upper part of the inner wall of the cabinet 1, so that the exhaust gas is extracted through the inside of the limit frame 13 under the restriction of the limit frame 13. An installation ring 14 is fixedly connected to the middle of the top wall of the cabinet 1. The extraction pipe is installed through the installation ring 14. A rubber ring 15 is fixedly connected to the inner wall of the installation ring 14. A stabilizing mechanism 2 is provided on both the front and rear sides of the top wall of the cabinet 1.

[0037] Specifically, during the initial exhaust gas extraction process, the extraction pipe must first be fixedly installed to the top of the mounting ring 14 to ensure stable exhaust gas extraction. The exhaust gas is first effectively blocked by the connection of baffle 3 and baffle 4, ensuring it flows along a predetermined path. The exhaust gas then enters the limiting frame 13, which ensures smooth entry into the sliding shell 10. The exhaust gas undergoes preliminary filtration through the filter plate 11, and then continues into the filter element 12. The filter element 12 further removes fine particles and harmful substances from the exhaust gas. Through the dual filtration of the filter plate 11 and filter element 12, the exhaust gas purification effect is achieved. The system has been upgraded to meet higher environmental standards. However, filter element 12 will gradually fail during long-term use and therefore needs to be replaced regularly. When filter element 12 needs to be replaced, the operator can activate the hydraulic rod 8 to drive the concave plate 9 to move. The movement of the concave plate 9 will cause the sliding shell 10 to slide, thereby exposing the filter element 12 for easy replacement. The replaced filter element 12 will slide out of the cabinet 1, allowing the operator to easily disassemble and replace it with a new filter element 12. This avoids the need for downtime for cleaning, shortens the replacement and maintenance time, improves work efficiency, ensures continuous operation of the equipment, and reduces production losses caused by maintenance.

[0038] Reference Figure 1, Figure 2 and Figure 5 The stabilizing mechanism 2 includes two upright plates 201. The bottoms of the two upright plates 201 are fixedly connected to the front and rear sides of the top wall of the cabinet 1, respectively. The two upright plates 201 connect to the fixed plate 202. The fixed plate 202 is fixedly connected to one side of the upright plate 201, thereby the fixed plate 202 achieves the effect of the swing cylinder 203. The swing cylinder 203 is fixedly connected to the bottom wall of the fixed plate 202. When the swing cylinder 203 is activated, the rotating shell 204 is driven to rotate. The top of the swing cylinder 203 is fixedly connected to the rotating shell 204. A connecting rod 205 is fixedly connected to one side of the rotating shell 204. One end of the connecting rod 205 is... An arc-shaped shell 206 is rotatably connected via a torsion spring. The swinging of the rotating shell 204 causes the connecting rod 205 to rotate the arc-shaped shell 206, thus enabling the arc-shaped shell 206 to clamp and protect the outer wall of the extraction tube. The stabilizing mechanism 2 also includes two rubber pads 208, with their opposite sides fixedly connected to adjacent sides of the corresponding arc-shaped shells 206. These two rubber pads 208 enhance the protection of the outer wall of the extraction tube. Multiple arc grooves 207 are provided on one side of each of the two arc-shaped shells 206, improving their toughness. All arc grooves 207 are equidistantly spaced.

[0039] Specifically, by activating the swing cylinder 203, the rotating shell 204 is driven to rotate. The rotating shell 204 rotates according to a predetermined path and speed. The connecting rod 205, as a connecting component, transmits the rotational motion of the rotating shell 204 to the arc-shaped shell 206. The connection of the connecting rod 205 ensures the synchronous movement between the rotating shell 204 and the arc-shaped shell 206, allowing the arc-shaped shell 206 to rotate along with the rotating shell 204. As the arc-shaped shell 206 rotates, it gradually moves closer to one side of the extraction tube, making... Effective clamping of the extraction tube is achieved. As the arc-shaped shell 206 approaches the extraction tube, its inner arc-shaped structure fits against the outer wall of the extraction tube. To further ensure the fit between the arc-shaped shell 206 and the outer wall of the extraction tube, the presence of a torsion spring allows the arc-shaped shell 206 to generate a certain torque during rotation, thereby making the arc-shaped shell 206 fit the outer wall of the extraction tube even better. This fit not only ensures the stability of the extraction tube during use but also plays a protective role, while improving the service life of the extraction tube.

[0040] Reference Figure 1 , Figure 4 and Figure 5 A control switch 19 is fixedly connected to the left side of the cabinet 1. The control switch 19 is electrically connected to the hydraulic rod 8 and the swing cylinder 203 respectively. A handle 17 is fixedly connected to the left side of the cabinet door 5. A rubber sleeve 18 is fixedly connected to the middle of the handle 17. A sealing ring 16 is fixedly connected to the right side of the cabinet door 5.

[0041] Specifically, the control switch 19, which is electrically connected to the hydraulic rod 8 and the swing cylinder 203 respectively, enables the device to be opened and closed. The handle 17 and the rubber sleeve 18 facilitate the opening of the cabinet door 5.

[0042] Reference Figure 1 and Figure 2 A placement rack 23 is fixedly connected to the right side of the cabinet 1, and a fixed platform 22 is fixedly connected to the bottom front side of the cabinet 1; support bases 20 are fixedly connected to the four corners of the bottom wall of the cabinet 1, and support columns 21 are fixedly connected inside the support bases 20.

[0043] Specifically, the placement rack 23 facilitates the placement of the sample, and the multiple support bases 20 and support columns 21 improve the stability of the device during operation.

[0044] Working principle: When exhaust gas extraction begins, the extraction pipe is fixedly installed to the top of the mounting ring 14, and then the exhaust gas extraction operation is started. The exhaust gas is effectively blocked by baffles 3 and 4, allowing it to enter the sliding shell 10 through the inside of the limiting frame 13. The exhaust gas first undergoes preliminary filtration through the filter plate 11, and then is adsorbed by the filter element 12, thus improving the filtration and purification effect. When the filter element 12 needs to be replaced, the hydraulic rod 8 is activated, causing its right end to drive the concave plate 9 to move. The sliding shell 10 slides under the action of the concave plate 9, thus completing the replacement of the filter element 12. After use, the filter element 12 slides out of the cabinet 1, making it easy for operators to disassemble and replace, avoiding the need to stop the machine for cleaning, thus shortening the replacement and maintenance time and improving work efficiency. Furthermore, by activating the swing cylinder 203, it drives the rotating shell 204 to rotate, which, under the connection of the connecting rod 205, causes the arc-shaped shell 206 to rotate synchronously, moving it closer to one side of the extraction tube and clamping it. At the same time, under the rotation connection of the torsion spring, the arc-shaped shell 206 fits more closely to the outer wall of the extraction tube, thereby achieving the purpose of protecting the outer wall of the extraction tube and improving the service life of the extraction tube.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
