Description

Technical Field

[0001] This utility model relates to the technical field of paint mixing kettles, specifically to a cleaning spray device for processing water-based industrial paint mixing kettles. Background Technology

[0002] In the cleaning process of water-based industrial paint mixing tanks, manual rinsing, fixed ball spraying, or simple spray booms are commonly used. These traditional methods have the following problems:

[0003] First, manual cleaning poses safety hazards, is inefficient, and consumes a large amount of water. Second, fixed spray devices have blind spots and cannot fully cover the inner wall of the vessel. Third, most automated cleaning equipment has a complex structure, requires special tools or modifications to the vessel opening for installation, has poor adaptability, and has a messy pipeline layout.

[0004] Of particular concern is that existing open or semi-open cleaning operations generate a large amount of aerosols containing paint mist and water vapor, which not only pollutes the workshop environment and endangers the health of employees, but also increases the burden of subsequent cleaning. Although some equipment has introduced negative pressure suction function, its suction port and spray mechanism are often designed separately, resulting in poor coordination, chaotic airflow organization, low capture efficiency, low overall system integration, and cumbersome operation. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a cleaning spray device for processing water-based industrial paint mixing tanks, which can solve the following problems:

[0006] Problems include low cleaning efficiency, poor equipment adaptability and complicated installation, water waste and secondary treatment, and difficulty in adsorbing and cleaning the water mist generated during the cleaning process.

[0007] To solve the above-mentioned technical problems, the present invention proposes the following technical solution:

[0008] A cleaning spray device for processing water-based industrial paint mixing tanks includes a support assembly, which is semi-circular in shape and has two sets arranged opposite each other. The opposite ends of the two sets of support assemblies are connected by a horizontally arranged telescopic metal frame. A spray hood is located below the support assembly and has a conical structure that is smaller at the top and larger at the bottom. A spray assembly is located inside the spray hood. A lifting drive mechanism is connected between the telescopic metal frame and the top of the spray hood to drive the spray hood and spray assembly to lift. The support assembly includes an outer guide seat and a filter box that are fixedly connected. The outer guide seat is arranged along the arc-shaped outer surface of the filter box. The outer surface of the outer guide seat has a water inlet, and its inner surface has a guide port between it and the filter box. The filter box contains a filter plate with a water outlet on its surface. The water outlet is connected to the spray assembly through a water supply pipe. The outer surface of the outer guide seat also has an external adsorption connection port, which is connected to the top of the spray hood through an adsorption pipe.

[0009] Furthermore, there are three sets of retractable metal frames, the outer ends of which are fixedly connected to the side wall of the filter box; the lifting drive mechanism is an electric telescopic rod, the top of which is fixed to the bottom of the middle section of the retractable metal frame, and the bottom of which is fixedly connected to the center of the top of the spray cover.

[0010] Furthermore, a cross-shaped fixing frame is fixedly connected to the outside of the electric telescopic pole, and the bottom end of the fixing frame is fixedly connected to the top of the spray cover.

[0011] Furthermore, the external guide seat includes an arc-shaped water inlet chamber and an independent adsorption chamber. The water inlet and the guide port are connected to the water inlet chamber; the external adsorption connection port is connected to the adsorption chamber.

[0012] Furthermore, the filter box has a partitioned chamber on one side of the adsorption cavity, and the adsorption tube extends downward along the chamber.

[0013] Furthermore, the filter plate has a lateral protrusion in the middle section of the filter box, located between the flow guide and the outlet. The filter plate has a detachable multi-layer filter element structure.

[0014] Furthermore, the spray assembly includes a ring frame fixedly connected to the inner side of the lower section of the spray hood and multiple spray heads communicating with its inner surface. The top of the ring frame is provided with a water supply connection port, which is connected to the water outlet through a water supply pipe.

[0015] Furthermore, the spray head is L-shaped, with its bottom end tilted outwards and protruding below the spray cover.

[0016] Furthermore, both the water supply pipe and the adsorption pipe are corrugated telescopic pipes.

[0017] Furthermore, a soft silicone sealing lip is provided at the bottom edge of the spray cover.

[0018] As can be seen from the above technical solution, the beneficial effects of this utility model are:

[0019] 1. This utility model integrates the external flow guide seat, filter box, telescopic frame, fixing point of electric telescopic rod, and interface of negative pressure adsorption channel into a semi-circular support component, making the entire device a complete single unit. It realizes rapid mounting and hanging installation, size self-adaptation, and pre-integration of three major functions: water supply, filtration, and adsorption, greatly simplifying the complexity of on-site pipeline connection and installation.

[0020] 2. In this utility model, the external guide seat is divided into an inlet chamber and an adsorption chamber. The two chambers are physically isolated and extended through the partition chamber in the filter box to achieve dual function of a single component. The cleaning liquid flows in from one side, and the waste liquid mist generated during cleaning is simultaneously drawn out from the other side, forming an efficient inlet-outlet flow field. This avoids the problem of tangled and messy inlet and outlet pipes in traditional designs and ensures the synchronicity of spraying and adsorption from a structural perspective.

[0021] 3. This utility model combines a conical spray hood, a bottom soft silicone sealing lip, a top adsorption tube, and an inner ring frame spray head to form a dynamic, relatively sealed cleaning chamber inside the vessel opening. The spray head sprays at the bottom, and the negative pressure suction port collects at the top, realizing a closed-loop operation mode of bottom spraying and top suction. It can instantly capture splash droplets and volatile gases, resulting in significant environmental benefits.

[0022] 4. In this utility model, the spray head is L-shaped and tilted outward at 30°-45°, which matches the inner wall shape of the conical spray hood. By utilizing the nozzle angle and hood structure, the water flow is guided to form a vortex or reflective flow with stronger shearing force on the vessel wall, which can more effectively flush away the attached substances, improve cleaning efficiency and reduce dead corners.

[0029] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0030] See Figure 1-3 As shown, a cleaning spray device for processing water-based industrial paint mixing tanks includes a support assembly 1, a spray hood 2, and a spray assembly 3 arranged sequentially from top to bottom. The support assembly 1 is semi-circular with two sets arranged opposite each other. The opposite ends are connected by three sets of telescopic metal frames that are sleeved together. The frames are horizontally arranged. The outer end of the frame is fixedly connected to the inner end of the filter box 5 in the two sets of support assemblies 1. A telescopic rod 13 is fixedly connected to the bottom end of the frame in the middle section. The telescopic rod 13 is an electric telescopic rod. The bottom end is fixedly connected to the top of the spray hood 2 at the center position. A fixing frame 17 arranged in a "+" shape is fixedly connected to the outer side of the telescopic rod 13. The bottom end of the fixing frame 17 is also fixedly connected to the top surface of the spray hood 2.

[0031] The support assembly 1 includes an outer guide seat 4 and a filter box 5 that are fixedly connected. The outer guide seat 4 is arc-shaped, while the filter box 5 is semi-circular. The outer guide seat 4 is set along the outer arc-shaped outer surface of the filter box 5, and the two are semi-circular in total. The outer surface of the outer guide seat 4 has an inlet 6 that connects to an external water inlet pipe. The inner surface of the outer guide seat 4 and the filter box 5 have a guide port 7. The middle section of the filter box 5 is fixedly connected to a horizontally arranged filter plate 8. The surface of the filter box 5 has an outlet 9. The bottom end of the outlet 9 is connected to a water supply pipe 12 located below the filter box 5. The outer surface of the outer guide seat 4 also has an external adsorption connection port 10 that connects to an external negative pressure pipe. The inner side of the external adsorption connection port 10 is fixedly connected to an adsorption pipe 11 located below the filter box 5. The filter box 5 has a separate set of compartments on the inner side corresponding to the external adsorption connection port 10. The adsorption pipe 11 extends downward along the compartment.

[0032] The spray assembly 3 includes a ring frame 14 located inside the spray cover 2 and a spray head 15 connected to its inner surface. Water supply ports 16 are fixedly connected to both sides of the top of the ring frame 14, and the water supply ports 16 are also connected to the bottom end of the water supply pipe 12.

[0033] In this embodiment of the utility model, two sets of semi-circular support components are connected by three sets of retractable metal frames. The frames are made of high-strength aluminum alloy with epoxy coating for corrosion protection. The telescopic rod 13 is an electric push rod with a built-in limit sensor. The fixing frame 17 is a stainless steel cross bracket, which is fastened to the top of the spray cover 2 with bolts. Half of the inner half of the outer guide seat 4 is set as a polished arc-shaped inner cavity. The inlet 6 and the guide port 7 are located on the inner and outer surfaces of this section of the outer guide seat 4, while the outer adsorption connection port 10 is located at the position of another section of the outer guide seat 4. The filter box 5 is set to fit the upper inner surface of the outer guide seat 4. The filter plate 8 is set in a horizontally protruding position between the inlet 6 and the outlet 9. The filter plate 8 has a multi-layer structure, with the upper layer being a stainless steel woven mesh and the lower layer being a sintered ceramic filter element. It is removable and replaceable from the inner side of the filter box 5.

[0034] The outlet 9 and the water supply pipe 12 are connected by a quick-connect sealing joint. Both the adsorption pipe 11 and the water supply pipe 12 are made of EPDM rubber corrugated telescopic pipes with embedded stainless steel spiral wires. The water supply pipe 12 is vertically installed through the spray cover 2, while the adsorption pipe 11 is embedded in the top surface of the spray cover 2 and connected to it. The spray cover 2 is tapered in shape with a smaller top and a larger bottom. A porous adsorption plate is provided between the top and the adsorption pipe 11. A soft silicone sealing lip is provided at the bottom edge to fit the vessel mouth. The ring frame 14 is fixedly connected to the inner surface of the lower section of the spray cover 2. The ring frame 14 is hollow inside. Multiple sets of spray heads 15 are evenly distributed along the inner surface of the ring frame 14.

[0035] The ring frame 14 is made of seamless stainless steel tube with mirror polished inner wall. A silicone sealing ring is installed at the interface with the inner side of the spray cover 2. The spray head 15 is L-shaped with the bottom end tilted outward and exposed below the spray cover 2. The spray head 15 is specifically set as a fan-shaped spray nozzle with adjustable flow rate. It is made of ceramic and the spray direction is tilted at 30°-45° to ensure that it can cover the vessel wall and bottom corners. It is threadedly connected to the inner side of the ring frame 14.

[0036] This device is equipped with a waterproof and corrosion-resistant PLC (Programmable Logic Controller) control box, which is installed on support assembly 1. The control box integrates a power interface, a signal receiving module, and an output module.

[0037] When using this device, the entire device is placed at the top opening of the outer vessel body using external hoisting equipment for mounting. The spray bottom cover 2 and spray assembly 3 are located inside the outer vessel body. Since the filter box 5 is set to fit the upper inner surface of the outer guide seat 4, there is an annular excess space between the filter box 5 and the outer guide seat 4. This space allows the entire device and the top edge of the outer vessel body to be mounted. Then, the corresponding pipes are connected according to the positions of the water inlet 6 and the external adsorption connection port 10. The outer ends of the pipes are connected to the corresponding water supply equipment and negative pressure equipment.

[0038] External water is first delivered to the cavity at one end of the outer guide seat 4 through the pipe and the inlet 6, and then enters the filter box 5 through the guide port 7. After being filtered by the filter plate 8 inside the filter box 5, it is delivered to the water supply pipe 12 through the outlet 9. The water supply pipe 12 delivers the water source to the inside of the ring frame 14 through the water supply connection port 16 on the ring frame 14, and evenly delivers it to each spray head 15 for spraying.

[0039] During the cleaning spraying process, the telescopic rod 13 controls the spraying bottom cover 2 and the spraying components 3 inside it to be raised and lowered in the external vessel. The gas and water mist generated during the spraying cleaning process are uniformly introduced into the spraying bottom cover 2 and are adsorbed and treated by the adsorption tube 11.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
