Description

Technical Field

[0001] This utility model relates to the field of waste paint treatment technology, specifically a pretreatment device for recycling waste paint residue. Background Technology

[0002] In today's era of booming industrial development, paint coating, as a crucial step in giving products both aesthetic appeal and protective properties, is widely used in numerous fields such as automobile manufacturing, furniture production, architectural decoration, and shipbuilding. From the vibrant colors of car bodies to the exquisite coatings on furniture surfaces, from the dazzling exterior decorations of skyscrapers to the anti-corrosion treatment of ship decks, paint plays an indispensable role. However, the paint coating process inevitably generates a large amount of waste paint residue. This waste paint residue has a complex composition, including resins, pigments, solvents, and various additives. If it is carelessly discarded or improperly disposed of, it will not only cause a huge waste of resources but also cause serious environmental pollution.

[0003] Currently, through effective pretreatment and subsequent processing, waste paint residue can be transformed into valuable renewable resources for the production of building materials, fuels, fillers, and other products, achieving resource recycling and sustainable economic development. This not only helps reduce dependence on natural resources and lower production costs, but also effectively alleviates environmental pressure, aligning with the concept of green development.

[0004] Paint residue requires dehydration during pretreatment. Common dehydration methods include natural air drying and mechanical filtration. While natural air drying is lower in cost, it is extremely inefficient, highly susceptible to weather and environmental factors, and requires a large area, making it unsuitable for large-scale production. Although mechanical filtration can improve dehydration efficiency to some extent, its effect is not ideal for some highly viscous waste paint residue with high water content. Paint residue easily clogs the filter cloth, leading to insufficient filtration pressure and incomplete water removal. Moreover, frequent filter cloth replacement not only increases production costs but also affects production continuity, resulting in poor dehydration and low work efficiency.

[0005] Therefore, in order to address the above problems, the applicant needs to design a waste paint residue recycling pretreatment device to solve the problem. Utility Model Content

[0006] The purpose of this invention is to provide a pretreatment device for recycling waste paint residue, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pretreatment device for recycling waste paint sludge, including a base.

[0008] It also includes: a dewatering mechanism disposed above the base, and the dewatering mechanism is used to squeeze and dewater paint residue. The dewatering mechanism includes a support base fixedly connected to the base, and a servo motor is fixedly disposed above the support base. The output end of the servo motor is provided with a rotating shaft, and a screw conveyor is provided on the rotating shaft. A fixed plate is rotatably disposed on the rotating shaft, and a filter cylinder is fixedly disposed on the fixed plate. A squeezing plate is provided at the end of the filter cylinder away from the fixed plate. A connecting plate is fixedly disposed on the squeezing plate, and a cylinder is fixedly disposed on the connecting plate.

[0009] A support rod is fixedly connected to the base, and a filter mechanism is fixedly installed at the end of the support rod away from the base. The filter mechanism is used to filter and store waste paint.

[0010] Furthermore, a support plate is fixedly provided at the end of the cylinder away from the connecting plate, and the support plate is fixedly connected to the support base.

[0011] Furthermore, the filter cartridge is provided with several mounting plates, and the mounting plates, together with the extrusion plates, are used to pressurize the paint residue to produce water.

[0012] Furthermore, a stabilizing seat is rotatably mounted on the rotating shaft, and the stabilizing seat is fixedly connected to the support seat.

[0013] Furthermore, the filtration mechanism includes a buffer pool fixedly connected to the support rod, and a drain pipe is connected to the buffer pool.

[0014] Furthermore, a fixed block is fixedly installed inside the cache pool, a mounting frame is placed on the fixed block, and a filter screen is fixedly installed inside the mounting frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the waste paint residue recycling pretreatment device facilitates the dehydration of paint residue, and the dehydration is convenient and efficient. The specific details are as follows:

[0016] When in use, the waste paint residue recycling pretreatment device feeds the waste paint residue into the filter cylinder. The servo motor drives the rotating shaft and screw conveyor to rotate, conveying the paint residue towards the extrusion plate at the end of the filter cylinder for initial extrusion and dehydration. The water is discharged through the pores of the filter cylinder. At the same time, the piston rod of the cylinder pushes the extrusion plate through the connecting plate to apply strong linear pressure to the paint residue. This, together with the rotating screw conveyor, forms strong extrusion and shearing, breaking down the structure of the paint residue and deeply squeezing out the internal water. The desorbed waste paint water passes through the filter cylinder and flows into the filtration mechanism below. The filtered liquid enters the buffer tank for temporary storage and is finally discharged and collected through the drain pipe. This facilitates the dehydration of the paint residue, and the dehydration is convenient and efficient. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] like Figures 1-4 As shown, the present invention discloses a waste paint residue recycling pretreatment device, including a base 1, and further including: a dewatering mechanism 2 disposed above the base 1, the dewatering mechanism 2 being used to squeeze and dewater the paint residue, the dewatering mechanism 2 including a support base 20 fixedly connected to the base 1, a servo motor 21 fixedly disposed above the support base 20, a rotating shaft 22 disposed at the output end of the servo motor 21, a screw conveyor 23 disposed on the rotating shaft 22, a fixed plate 24 rotatably disposed on the rotating shaft 22, a filter cylinder 25 fixedly disposed on the fixed plate 24, a pressing plate 26 disposed at the end of the filter cylinder 25 away from the fixed plate 24, a connecting plate 29 fixedly disposed on the pressing plate 26, and a cylinder 28 fixedly disposed on the connecting plate 29; a support rod 10 fixedly connected to the base 1, a filtering mechanism 3 fixedly disposed at the end of the support rod 10 away from the base 1, and the filtering mechanism 3 being used to filter and store waste paint water.

[0024] A support plate 280 is fixedly installed at the end of the cylinder 28 away from the connecting plate 29, and the support plate 280 is fixedly connected to the support base 20. The cylinder body of the cylinder 28 is firmly fixed to the support base 20 through the support plate 280, providing a solid support point for the reaction force of the cylinder 28. This ensures that the entire force application system is stable and reliable when the cylinder 28 pushes the extrusion plate 26 to apply high pressure to the paint residue, avoiding pressure loss or equipment vibration caused by unstable installation of the cylinder 28, thereby improving the pressure stability and dewatering efficiency during extrusion dewatering.

[0025] The filter cartridge 25 is provided with several mounting plates 260, and the mounting plates 260 work together with the extrusion plate 26 to pressurize the paint residue to release water. The mounting plates 260 and the moving extrusion plate 26 work together to produce a shearing and kneading effect on the paint residue during the extrusion process. This can not only more effectively break down the structure of the sticky paint residue, but also release the water it contains.

[0026] A stabilizing seat 27 is rotatably mounted on the rotating shaft 22, and the stabilizing seat 27 is fixedly connected to the support seat 20. The stabilizing seat 27 provides an additional support point on the rotating shaft 22, which greatly enhances the rigidity and stability of the rotating shaft 22 when it rotates at high speed and is subjected to the reaction force of paint residue extrusion.

[0027] The filtration mechanism 3 includes a buffer pool 30 fixedly connected to the support rod 10, and a drain pipe 31 is connected to the buffer pool 30, which realizes the effective collection, temporary storage and orderly discharge of waste paint water generated during the extrusion dehydration process.

[0028] A fixing block 32 is fixedly installed inside the buffer pool 30. An installation frame 33 is placed on the fixing block 32, and a filter screen 11 is fixedly installed inside the installation frame 33. The filter screen 11 can intercept fine paint residue particles that may be carried in the wastewater squeezed out from the dewatering mechanism 2, preventing these particles from entering the buffer pool 30 or clogging the drain pipe 31, ensuring the smooth discharge of wastewater, and improving the relative cleanliness of the collected wastewater, which is convenient for subsequent treatment.

[0029] Working principle: When using this waste paint residue recycling pretreatment device, the waste paint residue is fed into the filter cylinder 25. The servo motor 21 is started to drive the rotating shaft 22 and the screw conveyor 23 to rotate, which conveys the paint residue towards the extrusion plate 26 at the end of the filter cylinder 25 and performs preliminary extrusion and dewatering. The water is discharged through the pores of the filter cylinder 25. At the same time, the piston rod of the cylinder 28 pushes the extrusion plate 26 to apply strong linear pressure to the paint residue through the connecting plate 29. Together with the rotating screw conveyor 23, it forms strong extrusion and shearing, destroying the structure of the paint residue and deeply squeezing out the internal water. The dewatered waste paint water passes through the filter cylinder 25 and flows into the filtration mechanism 3 below. It first passes through the filter screen 11 in the mounting frame 33 to intercept fine solid particles. The filtered liquid enters the buffer tank 30 for temporary storage and is finally discharged and collected through the drain pipe 31. This facilitates the dewatering of the paint residue, and the dewatering is convenient and efficient, completing the dewatering pretreatment.

[0030] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
