Description

Technical Field

[0001] The present application relates to a spray gun cleaning technology, and in particular to a cleaning device for a drying tower spray gun. Background Art

[0002] A drying tower is a type of drying equipment that primarily utilizes heat exchange to direct liquid material from the tower's spray guns into the interior of the tower. This heat is exchanged with the high-temperature gas flowing through the tower to produce the desired product. Due to the high temperature within the drying tower, material within the spray guns is prone to clumping. To ensure proper operation, the spray guns must be cleaned regularly.

[0003] Currently, when cleaning a spray gun, the gun to be cleaned is first removed from the drying tower. High-pressure liquid is then introduced into the gun from one end, and waste liquid is discharged from the other end to complete the internal cleaning of the gun. For spray guns with smaller apertures, conventional high-pressure liquids are ineffective in cleaning debris within the gun. Therefore, the prior art also utilizes high-pressure steam to flush and clean the gun. The high-pressure steam is generated by a high-pressure steam cleaning machine, the liquid outlet of which is connected to the gun, allowing the high-pressure steam to pass through the gun and clean the inner wall of the gun.

[0004] However, during the cleaning process, the high-pressure steam cleaning machine and the spray gun are easily separated, and the high-pressure steam passing through the spray gun is sprayed randomly, causing the high-pressure steam to easily scatter, making the current high-pressure steam cleaning spray gun process a safety hazard.

[0032] Through the above - mentioned drawings, specific embodiments of the present application have been shown, and there will be more detailed descriptions hereinafter. These drawings and written descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed description of the specific embodiment

[0033] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0034] In the description and claims of this application and the above-mentioned drawings, terms such as "first", "second", "third", "fourth", etc. (if any) are used to distinguish similar objects and do not necessarily describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of this application described herein, for example, can be implemented in an order other than those illustrated or described herein.

[0035] In the embodiments of this application, words such as "exemplary" or "for example" are used to represent examples, illustrations or explanations. Any embodiment or design solution described as "exemplary" or "for example" in this application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0036] In the prior art, when cleaning a spray gun with high-pressure liquid, after the pipeline for providing high-pressure liquid (high-pressure water) and one end of the spray gun are fixed, the spray gun to be cleaned is fixed by manual holding, and then the other end of the spray gun is oriented towards a specific drainage trough. The valve of the high-pressure liquid pipeline is opened, and the high-pressure liquid is introduced from one end of the spray gun. The high-pressure liquid impacts the inner wall of the spray gun to clean the inner wall of the spray gun. The dirt after flushing is discharged together with the waste liquid from the other end of the spray gun, and the waste liquid is collected through the drainage trough.

[0037] However, if the high-pressure liquid is replaced with high-pressure steam, at this time, due to the relatively high temperature of the high-pressure steam and the good heat conduction effect of the entire spray gun, after the pipeline for providing high-pressure steam (high-pressure steam cleaner) and the spray gun are fixedly connected, the spray gun can only be placed on the ground, and then the high-pressure steam cleaner is started. The high-pressure steam generated by the high-pressure steam cleaner passes through the spray gun to clean the inner wall of the spray gun.

[0038] After the high-pressure steam generated by the high-pressure steam cleaner enters the spray gun, due to the scaling on the inner wall of the spray gun and the change in the pipe diameter at the nozzle position of the spray gun, the resistance becomes larger after the high-pressure steam enters the spray gun (the fluid pressure in the spray gun becomes larger). If the spray gun is placed randomly, the air pressure change is likely to cause the spray gun to swing, resulting in the problem that the connection position between the high-pressure steam cleaner and the spray gun becomes disconnected. There is a safety hazard and it is also easy to damage the spray gun. Moreover, after the high-pressure steam is discharged from the spray gun, the high-pressure steam is discharged in a divergent state, resulting in the dispersion of the high-pressure steam, which also poses a safety hazard problem.

[0039] Therefore, to solve the above problems, in the present application, a cleaning device is provided, which can fix the spray gun to be cleaned to avoid the problem of easy swinging caused by the change of air pressure inside the spray gun, and then separating from the high-pressure steam cleaner. At the same time, a connecting pipe is also provided to adapt to high-pressure steam cleaners of different models and different lengths, ensuring that the high-pressure steam generated by the high-pressure steam cleaner can smoothly enter the spray gun to be cleaned. Finally, the waste liquid collection component is used to centrally collect the waste fluid after cleaning to avoid high-temperature steam scattering and hurting people.

[0040] The following will specifically describe the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0041] Referring to Figure 1 、 Figure 2 、 Figure 3 As shown, a cleaning device for a spray gun of a drying tower includes a fixing component 100, a connecting pipe 200, and a waste liquid collection component 300. The fixing component 100 includes a fixing frame 110 and at least one fixing member 120. The fixing member 120 is connected to the fixing frame 110, and the fixing member 120 is used to fix the spray gun 400 to be cleaned. One end of the connecting pipe 200 is used for detachable connection with one end of the spray gun 400, and the other end of the connecting pipe 200 is used for connection with the high-pressure steam cleaner 500. The waste liquid collection component 300 includes a waste liquid tank 310. The waste liquid tank 310 is connected to the fixing frame 110, and the waste liquid tank 310 is used for detachable connection with the other end of the spray gun 400.

[0042] It can be understood that the spray gun 400 is generally similar to a pipe structure and has two open ends. The diameter of one open end (the nozzle end of the spray gun 400) is smaller than that of the other open end. The scale on the inner wall of the spray gun 400 can be cleaned by high-pressure steam impact and dissolution. Therefore, one end of the spray gun 400 to be cleaned needs to be connected to the machine providing high-pressure steam, and the other end of the spray gun 400 is used to discharge waste liquid to ensure that the high-pressure steam can pass through the spray gun 400 to clean the inner wall of the spray gun 400.

[0043] When cleaning the spray gun 400, due to the high temperature of the high-pressure steam and the good heat conduction of the spray gun 400, currently, there is no specific mechanism to fix the spray gun 400; and due to the change of the internal air pressure of the spray gun 400, the spray gun 400 is prone to swing, resulting in the disconnection of the connection between the spray gun 400 and the high-pressure steam cleaner 500. Therefore, in this application, a corresponding fixing component 100 is provided. The fixing component 100 includes a fixing frame 110 and at least one fixing member 120. The fixing frame 110 is used to install the waste liquid collection component 300, place the connecting pipe 200, and fix the spray gun 400 to be cleaned. By placing the fixing frame 110 at a specific position, the cleaning operation of the spray gun 400 can be ensured to be carried out at a specific position, ensuring that the cleaning device of this application can be integrally placed or moved, making it more convenient to use. The fixing member 120 is fixed to the fixing frame 110, and the fixing member 120 is detachably connected to the spray gun 400 to be cleaned, which facilitates the disassembly and assembly of the spray gun 400 on the fixing frame 110 for cleaning different spray guns 400. The fixing member 120 can adopt an electric clamp or a manual clamp in the prior art, which can realize the detachable connection between the spray gun 400 and the fixing member 120.

[0044] After the spray gun 400 to be cleaned is fixed in place on the fixing frame 110, the spray gun 400 is connected to the high-pressure steam cleaner 500 by using the connecting pipe 200. The connection method between the connecting pipe 200 and the spray gun 400, as well as the connection method between the connecting pipe 200 and the high-pressure steam cleaner 500, are both pipe-to-pipe connections. The connection method between pipes can adopt clamp connection, threaded connection, etc. to ensure the detachable connection between the connecting pipe 200 and the spray gun 400. The connecting pipe 200 plays a transitional role to ensure the communication between the high-pressure steam cleaner 500 and the spray gun 400 to be cleaned. At the same time, the connecting pipe 200 is made of a high-temperature resistant hose, and the length of the connecting pipe 200 is not limited, so that at any position of the spray gun 400 on the fixing frame 110, the spray gun 400 and the high-pressure steam cleaner 500 can communicate under the action of the connecting pipe 200, ensuring that high-pressure steam can be introduced into one end of the spray gun 400 to be cleaned.

[0045] The high-pressure steam enters the inner wall of the spray gun 400 to dissolve and impact the scale in the spray gun 400, and the scale deposits are finally exported from the other end of the spray gun 400 along with the fluid. To prevent the high-pressure fluid exported from the spray gun 400 from spreading everywhere, this application also provides a waste liquid collection component 300. The waste liquid tank 310 of the waste liquid collection component 300 can be used for the end of the spray gun 400 to be inserted. Then, the high-pressure steam exported from the spray gun 400 will spread everywhere in the waste liquid tank 310. By using the waste liquid tank 310 to limit the spreading area of the high-pressure steam, it can prevent high-pressure steam from hurting people.

[0046] Specifically, such as Figure 1As shown, the fixing frame 110 of the present application is a horizontally arranged rectangular frame structure, and a plurality of reinforcing rods are arranged in the middle of the fixing frame 110. The waste liquid tank 310 is fixed to the fixing frame 110 and is located at one end of the fixing frame 110 in the longitudinal direction. The fixing member 120 and the waste liquid tank 310 are spaced apart along the longitudinal direction of the fixing frame 110. When in use, one end of the spray gun 400 is inserted into the waste liquid tank 310, and then the spray gun 400 is fixed to the fixing frame 110 using the fixing member 120. The other end of the spray gun 400 is then connected to the high-pressure steam cleaning machine 500 through the connecting pipe 200. The high-pressure steam cleaning machine 500 is started, and the high-pressure steam generated flows through the spray gun 400 to clean the inner wall of the spray gun 400. After cleaning is completed, the high-pressure steam cleaning machine 500 is turned off, and the spray gun 400 is then removed from the fixing frame 110 to clean the next spray gun 400.

[0047] The cleaning device provided in the present application fixes the spray gun 400 to be cleaned by means of a fixing assembly 100; at the same time, a connecting pipe 200 is used to ensure that the high-pressure steam output by the high-pressure steam cleaning machine 500 can be smoothly introduced into the spray gun 400 to be cleaned; finally, a waste liquid collection assembly 300 can be used to centrally collect the high-temperature steam passing through the spray gun 400 to be cleaned; to ensure that the spray gun 400 is not easily separated from the high-pressure steam cleaning machine 500 during the cleaning process, and at the same time, the high-pressure steam after cleaning can be collected, thereby avoiding the safety hazard of using high-pressure steam to clean the spray gun 400, and can also effectively and thoroughly clean the attachments in the spray gun 400, thereby improving the cleaning efficiency of the spray gun 400 and ensuring product quality and safety.

[0048] In one possible implementation, the fixing member 120 includes a connecting column 122 and a fixing clamp 121, and the fixing clamp 121 is connected to the connecting column 122; the connecting column 122 is fixed to the fixing frame 110, and the fixing clamp 121 is used to fix the spray gun 400; the spray gun 400 is arranged at an angle on the fixing clamp 121, and the inclined upper end of the spray gun 400 is connected to the connecting pipe 200, and the inclined lower end of the spray gun 400 is connected to the waste liquid tank 310.

[0049] It is understandable that during the cleaning process of the spray gun 400, the tilt angle of the spray gun 400 has a certain impact on the flow rate of the high-pressure steam in the spray gun 400. When the spray gun 400 is set horizontally or tilted, the flow rate of the high-pressure steam in the spray gun 400 is different. In order to increase the flow rate of the high-pressure steam in the spray gun 400 and improve the impact effect of the fluid on the inner wall structure of the spray gun 400, the spray gun 400 of the present application is tilted on the fixed frame 110, and the tilted upper end of the spray gun 400 is connected to the connecting pipe 200, and the tilted lower end of the spray gun 400 is connected to the waste liquid tank 310, so that the high-pressure steam flows through the spray gun 400 at a higher flow rate.

[0050] To achieve the inclined fixation of the spray gun 400 on the fixed frame 110, the fixing member 120 of the present application includes a connecting column 122 and a fixing clip 121. The connecting column 122 is vertically arranged and fixedly connected to the fixed frame 110. The connecting column 122 raises the fixing clip 121. After the fixing clip 121 fixes the spray gun 400, the height difference between the two ends of the spray gun 400 arranged in an inclined manner can be compensated by the height of the connecting column 122, ensuring that the spray gun 400 can be arranged in an inclined manner on the fixed frame 110, and the lower inclined end of the spray gun 400 can be connected to the waste liquid tank 310.

[0051] Specifically, as Figure 1 , Figure 3 shown, in the present application, two fixing members 120 are arranged on the fixed frame 110, and the two fixing members 120 are arranged at intervals along the length direction of the fixed frame 110. Among them, the length of the connecting column 122 of the fixing member 120 close to the waste liquid tank 310 is less than the length of the connecting column 122 of the other fixing member 120. The height difference between the lengths of the two connecting columns 122 can limit the inclination angle of the spray gun 400 on the fixed frame 110.

[0052] To enable the fixing clip 121 to fix the tubular spray gun 400, the fixed frame 110 of the present application includes an arc-shaped fixed clip seat 1211 and an arc-shaped movable clip seat 1213. The fixed clip seat 1211 is fixed to the connecting column 122. The arc directions of the fixed clip seat 1211 and the movable clip seat 1213 are relatively arranged outward to form a clamping space for the spray gun 400, and the distance between the fixed clip seat 1211 and the movable clip seat 1213 is adjustable. The fixed clip seat 1211 and the movable clip seat 1213 are movably connected by a limit bolt 1212. The limit bolt 1212 is threadedly connected to the fixed clip seat 1211. A fixing bolt 1214 parallel to the limit bolt 1212 is arranged on the fixed clip seat 1211. The fixing bolt 1214 is threadedly connected to the fixed clip seat 1211. A clamping groove is arranged on the movable clip seat 1213, and the clamping groove is clamped with the fixing bolt 1214.

[0053] During use, separate the clamping groove of the movable clip seat 1213 from the fixing bolt 1214 along the direction away from the fixing bolt 1214, then place the spray gun 400 on the fixed clip seat 1211, and then connect the clamping groove of the movable clip seat 1213 with the fixing bolt 1214. Rotate the fixing bolt 1214, or rotate the fixing bolt 1214 and the limit bolt 1212 simultaneously to fix the spray gun 400 between the fixed clip seat 1211 and the movable clip seat 1213, and complete the connection between the fixing clip 121 and the spray gun 400.

[0054] Among them, when the fixed clip seat 1211 is fixed to the connecting column 122, it needs to be arranged obliquely so that the arc-shaped groove of the fixed clip seat 1211 can fit the outer wall of the spray gun 400.

[0055] In this application, by using two fixing members 120, the spray gun 400 can be inclined on the fixing frame 110, increasing the flow rate of high-pressure steam through the spray gun 400 and improving the cleaning effect of foreign matters in the spray gun 400.

[0056] In a possible implementation, at least two moving wheels 111 are provided at the bottom of the fixing frame 110.

[0057] It can be understood that the various components of this application are basically concentrated on the fixing frame 110. Then, the installation position of the fixing frame 110 is equivalent to the installation position of the entire cleaning device of this application. To enable the cleaning device of this application to adapt to different production sites, moving wheels 111 are provided at the bottom of the fixing frame 110.

[0058] As Figure 1 shown, four moving wheels 111 distributed in a rectangle are provided at the bottom of the fixing frame 110. The moving wheels 111 are universal wheels or conventional rolling wheels, and at least one of the moving wheels 111 has a self-locking function. During use, the moving wheels 111 are used to move the entire cleaning device to adapt to different production environments.

[0059] In a possible implementation, a moving handle 112 is provided on the fixing frame 110, and the moving handle 112 is located in the upper middle part of the fixing frame 110.

[0060] It can be connected that when moving the entire cleaning device (fixing frame 110), an external force needs to be applied to the cleaning device to drive the fixing frame 110 to move. To facilitate the application of an external force to the fixing frame 110, a moving handle 112 is provided on the fixing frame 110.

[0061] As Figure 1 shown, the connecting column 122 of the fixing member 120 away from the waste liquid tank 310 is located at the tail of the fixing frame 110 in the length direction. This connecting column 122 is arranged such that the entire fixing frame 110 has a certain height in the vertical direction. The moving handle 112 of this application is fixed on this connecting column 122 to ensure that the installation height of the moving handle 112 matches the height of the operator, facilitating the operator to apply an external force.

[0062] In a possible implementation, a storage rack 113 is provided on the fixing frame 110, and the storage rack 113 is used to place the connecting pipe 200.

[0063] It can be understood that when the connecting pipe 200 is not in use, it needs to exist separately. To facilitate the centralized collection and management of the connecting pipe 200, a storage rack 113 is provided on the fixing frame 110, and the connecting pipe 200 during the idle period is wound around the storage rack 113 for collection.

[0064] Specifically, as Figure 1As shown, the storage rack 113 is on the connecting column 122 of the fixing member 120 away from the waste liquid tank 310, and the storage rack 113 and the moving handle 112 are on both sides of the connecting column 122. The storage rack 113 includes a horizontal rod 1132 and a vertical rod 1131. The horizontal rod 1132 is fixed to the connecting column 122, and the vertical rod 1131 is fixed to the horizontal rod 1132. The horizontal rod 1132, the vertical rod 1131 and the connecting column 122 form a storage groove for winding the connecting pipe 200, so as to realize the storage of the connecting pipe 200 on the fixing rack 110, achieve centralized management, and avoid the loss or damage of the connecting pipe 200.

[0065] In a possible implementation manner, a connecting hole 311 is provided on the waste liquid tank 310, and the other end of the spray gun 400 is inserted into the connecting hole 311.

[0066] It can be understood that the waste liquid tank 310 needs to facilitate the insertion of the spray gun 400, and at the same time, it is necessary to ensure that the high-pressure steam exported by the spray gun 400 can be blocked by the inner wall of the waste liquid tank 310. For this reason, a connecting hole 311 is provided in the upper middle part of the waste liquid tank 310, and the aperture of the connecting hole 311 needs to be larger than the diameter of the end of the spray gun 400 (the nozzle end of the spray gun 400), so that the end of the spray gun 400 can be inserted into the connecting hole 311.

[0067] Specifically, as Figure 1 、 Figure 2 shown, the waste liquid tank 310 has a rectangular box structure, and the connecting hole 311 is located on the side wall of the waste liquid tank 310 adjacent to the fixing member 120. The setting of the connecting hole 311 needs to ensure that the end of the spray gun 400 can be inserted into the waste liquid tank 310, and the spray gun 400 can be fixed by the fixing member 120. The setting of the connecting hole 311 facilitates the positioning of the spray gun 400 on the fixing rack 110. Taking the height of the connecting hole 311 as the height of the inclined lower end of the spray gun 400, so that the inclination angle of the spray gun 400 is a design parameter, so as to facilitate the setting of each fixing member 120 on the fixing rack 110.

[0068] In a possible implementation manner, a drain hole 313 is provided through the bottom of the waste liquid tank 310, and at least one guiding surface 312 is provided on the inner bottom of the waste liquid tank 310, and the guiding surface 312 is inclined towards the drain hole 313.

[0069] It can be understood that the waste liquid tank 310 has a function of collecting the cleaning waste liquid of the spray gun 400. To facilitate the external discharge of the collected waste liquid, a drain hole 313 is provided through the bottom of the waste liquid tank 310 in this application, and the waste liquid collected in the waste liquid tank 310 can be discharged through the liquid distribution hole.

[0070] To make the waste liquid tank 310 have a guiding effect, at least one guiding surface 312 is provided on the inner bottom of the waste liquid tank 310, and the guiding surface 312 is inclined towards the drain hole 313. In this application, as Figure 2As shown, the liquid discharge hole 313 is arranged at the middle position of the bottom of the waste liquid tank 310, and four guiding surfaces 312 are provided. The four guiding surfaces 312 are respectively matched with the four inner walls of the waste liquid tank 310, and the guiding surfaces 312 are inclined from the inner walls of the waste liquid tank 310 towards the liquid discharge hole 313. In this application, the guiding surfaces 312 can collect the waste liquid in the waste liquid tank 310 towards the liquid discharge hole 313, facilitating the diversion of the solid waste (scale) in the waste liquid towards the liquid discharge hole 313.

[0071] In a possible implementation manner, a liquid discharge pipe 330 is connected to the liquid discharge hole 313, and a valve 331 is provided on the upper liquid discharge pipe.

[0072] It can be understood that the liquid discharge hole 313 is used to discharge the waste liquid in the waste liquid tank 310. To facilitate the waste liquid discharged from the waste liquid tank 310 to enter a specific area (such as the sewage treatment system in the factory area), the liquid discharge hole 313 of this application is connected to a liquid discharge pipe 330. The liquid discharge pipe 330 can communicate with the sewage pipe in the factory building or with the sewage trench, and the waste liquid can be introduced into a specific area by using the sewage pipe.

[0073] Of course, the liquid discharge pipe 330 is also the liquid outlet pipe of the waste liquid tank 310. The waste liquid in the waste liquid tank 310 can be discharged by using the liquid discharge pipe 330, and the waste liquid discharged by the liquid discharge pipe 330 can be moved to a specific position through other transfer containers. As Figure 1 、 Figure 2 As shown, to facilitate the liquid discharge of the liquid discharge pipe 330 under specific circumstances, a valve 331 is provided on the upper liquid discharge pipe of this application. The liquid discharge situation of the liquid discharge pipe 330 is controlled through the valve 331, so as to centrally collect and process the waste liquid in the waste liquid tank 310.

[0074] In a possible implementation manner, the upper end of the waste liquid tank 310 is provided with an opening, and a tank cover 320 is provided at the opening end of the waste liquid tank 310. The tank cover 320 is arranged to open and close relative to the waste liquid tank 310.

[0075] It can be understood that the scale in the spray gun 400 is usually solid waste, and the solid waste is easily attached to the inner wall of the waste liquid tank 310 along with the high-pressure steam. Therefore, the waste liquid tank 310 needs to be cleaned regularly to reduce the foreign matter pollution during the cleaning process of the spray gun 400. As Figure 1 、 Figure 2 As shown, to facilitate the cleaning of the waste liquid tank 310, the upper end of the waste liquid tank 310 of this application is provided with an opening, and a tank cover 320 is provided at the opening end of the waste liquid tank 310. The tank cover 320 is arranged to open and close relative to the waste liquid tank 310. The setting of the tank cover 320 can not only prevent the high-pressure steam from spreading outside the waste liquid tank 310 during the cleaning process of the spray gun 400, but also facilitate the cleaning of the inner wall of the waste liquid tank 310.

[0076] In a possible implementation manner, an opening and closing handle 321 is provided on the tank cover 320.

[0077] To facilitate the opening and closing of the lid 320, as Figure 1 、 Figure 2 shown, the present application is provided with an opening and closing handle 321 on the lid 320. Through the opening and closing handle 321, it is convenient for the operator to apply an external force to facilitate the opening and closing of the lid 320.
