Description

Technical Field

[0001] The present invention belongs to the technical field of metal surface treatment, and specifically relates to an integrated production device for metal surfaces. Background Art

[0002] Refer to the document with the existing publication (announcement) number CN113000343A, which discloses a metal surface coating process. Metal surface coating is generally divided into two parts: one is the surface treatment of the metal before coating, also called pre-treatment technology; the other is the construction process of coating. Surface treatment is divided into mechanical and chemical methods according to the treatment method. The mechanical method is to remove the oxide layer, paint and rust on the metal surface through manual methods, electric tools, flame methods or sandblasting and shot blasting; while the chemical method is to remove oil, rust and clean the metal surface through chemical reactions. The quality of surface treatment directly affects the quality of coating, and is related to the rust resistance and life of metal workpieces. It is an important link that cannot be ignored.

[0003] In the existing technology, traditional shot blasting, spray pre-treatment and painting are usually carried out separately. Shot blasting generally uses a shot blasting machine to clean the metal surface and remove impurities such as oxide scale and rust; spray pre-treatment mainly uses spray equipment to degrease and wash the metal surface with water to prepare for subsequent painting; painting uses spraying or powder spraying to form a protective layer or decorative layer on the metal surface. Since the above-mentioned links are carried out separately, it is necessary to move and change equipment multiple times, which not only increases production time and labor costs and reduces production efficiency, but also because the process connection between different equipment is prone to problems, resulting in unstable metal surface treatment quality, affecting the final quality. Furthermore, since multiple equipment occupy a large space, for companies with limited space, it increases production costs and management difficulties. Utility Model Content

[0004] The purpose of this solution is to provide an integrated production device for metal surfaces to solve the problem of low production efficiency of existing metal coating processes.

[0005] In order to achieve the above-mentioned purpose, the present invention provides an integrated production device for metal surfaces, including a conveying device and a shot blasting device, a spraying device, a moisture drying furnace, a powder spraying device, a powder curing furnace, and a forced cooling device connected in sequence through the conveying device; the spraying device and the powder curing furnace are connected to a wastewater treatment device through a pipeline.

[0006] The principle of this solution is that workers place workpieces on conveyors in the loading area. These conveyors then transport the workpieces sequentially to the shot blasting equipment, spraying equipment, moisture drying furnace, powder spraying equipment, powder curing furnace, and forced cooling equipment. Once the workpieces are delivered to the corresponding equipment, they are then transported to the corresponding equipment for the corresponding process. The treated workpieces are then transported to the next process step via conveyors. After being processed in the forced cooling equipment, they are unloaded in the unloading area of ​​the conveyor, completing the entire surface coating process. Wastewater generated by the spraying equipment and powder curing furnace is treated and settled in wastewater treatment equipment to meet qualified discharge standards.

[0007] The effects of this solution are: (1) By integrating multiple processes into a continuous production process, the production efficiency of metal surface coating is improved. Traditional shot blasting, spray pretreatment and coating processes are usually carried out separately, which not only requires multiple handling and conversion of equipment, increases production time and labor costs, but also leads to unstable metal surface treatment quality, affecting the quality of the final product. However, this solution connects each processing process in sequence through conveying equipment, reduces the handling and conversion time of workpieces, realizes continuous production, and greatly improves production efficiency. The seamless connection between each process avoids the waiting time and labor waste caused by the dispersion of equipment in traditional production methods. (2) Due to the close connection of each process link, process fluctuations are reduced and the stability of metal surface treatment quality is guaranteed. In this solution, the entire production line can be centrally controlled by PLC, which can accurately control each process parameter to ensure that each workpiece can obtain consistent treatment effects. (3) By integrating multiple devices together, the equipment footprint is reduced and the production cost of the enterprise is reduced. For enterprises with limited space, this integrated production line has obvious advantages. (4) The shot blasting, spray pretreatment and coating integrated production line in this solution has broad application prospects. It is suitable for surface treatment of various metal products, such as automotive parts, machinery manufacturing, home appliance manufacturing, power equipment and other industries. With the continuous development of the manufacturing industry and the increasing requirements for environmental protection, this integrated production line will become a development trend in the field of metal surface treatment, providing strong support for enterprises to improve production efficiency, reduce costs and protect the environment.

[0008] Furthermore, a paint spraying room is provided at the rear end of the discharge port of the moisture drying furnace, and the paint spraying room is connected to the wastewater treatment equipment through a pipeline.

[0009] The principle and effect of this solution are that the discharge port of the moisture drying furnace is connected to the feed port of the powder spraying equipment or the paint spraying room, and powder spraying or paint spraying can be selected according to the process requirements.

[0010] Furthermore, the shot blasting equipment is a shot blasting wheel, which is connected to a longitudinal spiral, a transverse spiral and an elevator, and a separator is provided at the rear ends of the longitudinal spiral, the transverse spiral and the elevator; the spraying equipment includes a degreasing tank, a first water washing tank, a second water washing tank and a spraying tank which are arranged in sequence, and the degreasing tank, the first water washing tank, the second water washing tank and the spraying tank are provided with an automatic dosing device and a tank liquid detection device; the moisture drying furnace includes a gas heating device and a hot air circulation device; the forced cooling equipment is an exhaust device; the wastewater treatment equipment includes a flocculation sedimentation chamber, a carbon sand filter and a plate and frame filter press.

[0011] The principle and effect of this scheme are as follows: (1) The workpiece is transported to the shot blasting equipment. In the shot blasting room, the shot blaster projects the shot at high speed onto the surface of the workpiece to remove impurities such as oxide scale and rust. The cleaned shot is transported to the separator through the longitudinal spiral, transverse spiral and elevator, and the qualified shot is separated and recycled, while the impurities are discharged. (2) The workpiece after shot blasting enters the spraying equipment and goes through degreasing, first water washing, second water washing and three spraying processes in sequence to remove oil and impurities on the surface of the workpiece. At the same time, the spray liquid is circulated in the liquid tank, and the concentration and performance of the tank liquid are kept stable by the automatic dosing device and the tank liquid detection device. (3) The workpiece treated by the spray equipment enters the moisture drying furnace. Under the action of the gas heating system and the hot air circulation system, the moisture on the surface of the workpiece is dried. The temperature control system accurately controls the temperature in the furnace to ensure the drying effect. (4) According to the process requirements, the workpiece can enter the powder spraying equipment for powder spraying or enter the paint spraying room for painting. In the powder spraying equipment, the powder is fully fluidized in the powder box of the powder supply center, and the powder pump generates a siphon effect to transport the powder to the spray gun through the powder hose. The powder is charged by the corona area of ​​the spray gun electrode, making it electrostatically charged and adsorbed to the grounded workpiece surface. In the paint spraying room, the paint mist is processed by the filtration system to ensure that the discharged air meets environmental protection requirements. (5) The workpiece after powder spraying enters the powder curing furnace. Under the action of the gas heating system and the hot air circulation system, the powder is cured on the surface of the workpiece to form a solid coating. The temperature control system accurately controls the temperature in the furnace to ensure the curing effect. (6) The cured workpiece enters the forced cooling equipment and is forced to cool through the supply and exhaust air system, so that the workpiece temperature is quickly reduced to below the specified temperature. (7) The cooled workpiece is unloaded from the conveying equipment through the unloading area, completing the entire surface treatment and coating process.

[0012] Furthermore, a group of symmetrically arranged scraping assemblies including scrapers and springs are provided in the filter plate of the plate and frame filter press. The two scrapers are symmetrically slidably arranged on the upper and lower sides of the material port of the filter plate. One end of the spring is fixedly connected to the scraper, and the other end is fixedly connected to the filter plate.

[0013] The principle and effect of this solution are as follows: the sewage suspension is introduced from the material port of the filter plate and enters the chamber between the two filter plates for extrusion filtration treatment. During the liquid inlet process, the suspension with increasing volume pushes the two scrapers to move relative to each other and stretches the spring. When the filtration is completed, the two filter plates are separated by external components. After the filter cake is unloaded from the chamber, the two scrapers are reset to their initial position driven by the spring, thereby scraping off the sludge attached to the filter cloth, thereby cleaning the filter cloth and reducing the need for subsequent cleaning of the filter cloth.

[0014] Furthermore, a knocking assembly is provided in the filter plate, and the knocking assembly includes a rack and a cam. The rack is slidably provided in the filter plate, the cam is rotatably connected to the rack, and the cam is cooperated with the filter cloth in the filter plate; and a driving assembly is also included for driving the rack to move.

[0015] The principle and effect of this solution are as follows: (1) The drive assembly drives the rack to move, thereby rotating the cam. When the cam rotates, it will intermittently collide with the filter cloth, thereby loosening the filter cake on the filter cloth. This prevents the filter cake from being too tightly attached to the filter cloth when the two filter plates are removed, making it difficult to remove the filter cake from the cavity. (2) Through the cooperation of the cam and the filter cloth, the sludge that is tightly attached to the filter cloth can also be shaken off.

[0016] Furthermore, the driving assembly includes a gear, a ratchet and a pawl. The gear is rotatably arranged at one end of the scraper, the gear is engaged with the rack, the ratchet is coaxially connected to the gear, the ratchet is provided with an energy storage torsion spring, the pawl is arranged in the filter plate and cooperated with the ratchet, and the pawl is coaxially connected to a knob.

[0017] The principle and effect of this solution are as follows: when the scraper is pushed by the suspension, the gear and ratchet rotate, causing the energy-storage torsion spring inside the ratchet to deform and store energy. Simultaneously, the gear drives the rack, which in turn rotates the cam. When the scraper reaches its maximum travel, the ratchet is restrained by the pawl, keeping the internal energy-storage torsion spring in a charged state, and the rack moves to its maximum travel. After removing the two filter plates, the pawl is turned by the knob. Unrestrained by the pawl, the ratchet rotates the gear, resetting the rack. During this resetting process, the cam rotates and collides with the filter cloth, vibrating and separating the mud cake from the filter cloth. This prevents the filter cake from clinging too tightly to the cloth, making it difficult to remove from the cavity. Once the mud cake and the filter cloth are loosened, the filter cake is removed from the filter plate, and the scraper, driven by the spring, resets to remove the mud adhering to the filter cloth.

[0018] Furthermore, it also includes a spray assembly arranged in the filter plate, the spray assembly includes a pressure water pump and a water storage chamber, the water inlet end of the pressure water pump is connected to the water tank through a pipe, and the water outlet end of the pressure water pump is connected to the water storage chamber through a pipe; it also includes a turntable and a knocking ball, the turntable is coaxially fixedly connected to the ratchet, the knocking ball is slidably arranged in the turntable, the knocking ball is connected to a reset spring, the free end of the reset spring is fixedly connected to the turntable, and the knocking ball is arranged in conjunction with the pressure water pump; the water storage chamber is connected to a spray pipe, and the water outlet end of the spray pipe faces the filter cloth.

[0019] The principle and effect of this solution are as follows: when the ratchet rotates and drives the turntable to rotate synchronously, the knocking ball in the turntable is thrown out of the turntable under the action of the centrifugal force of the turntable, thereby knocking and pressing the water pump, so that the water in the water tank is pumped into the water storage chamber and flows out through the spray pipe to the filter cloth.

[0020] Furthermore, the spray pipe is connected to a plurality of spray heads, a valve is provided on the spray pipe, a reset torsion spring is passed through the connection point between the valve handle and the valve, and the valve handle is matched with the rack.

[0021] The principle and effect of this solution are as follows: when the rack is reset to its initial position, the mud cake on the filter cloth has been loosened by the vibration of the cam; when the mud cake is removed from the filter plate, the scraper is reset to its initial position; at this time, the rack has been reset to its initial position, and the rack pushes the valve handle to rotate, so that the liquid in the spray pipe flows out and is sprayed onto the filter cloth through the nozzle; the filter cloth is then cleaned with the cooperation of the water flow and the scraper, which makes it easier for the scraper to hang out the residual sludge on the filter cloth, and the cleaning effect of the filter cloth is better.

[0022] Furthermore, a first one-way valve is provided on the pipe connecting the water storage tank and the pressure water pump, a second one-way valve is provided on the pipe connecting the pressure water pump and the water storage chamber, and a third one-way valve is provided on the spray pipe.

[0023] The principle and effect of this solution is to make the liquid in the pipeline flow in a preset direction to prevent it from flowing back.

[0024] Furthermore, the filter plate is provided with a slide groove, and the rack is slidably connected to the slide groove; a guide groove is provided in the turntable, and the knocking ball is slidably connected to the guide groove.

[0025] The principle and effect of this solution are: this is the existing technology, the sliding groove and the guide groove provide positioning and guiding functions for the movement of the rack and the knocking ball respectively, avoiding dislocation during their movement process.

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the concept and technical effects of the present invention in conjunction with the embodiments, so that the purpose, features and effects of the present invention can be fully understood. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention:

[0033] Example 1:

[0034] See also Figure 1An integrated production device for metal surfaces includes a conveyor 1, and a shot blasting device 2, a spraying device 3, a moisture drying furnace 4, a powder spraying device 5, a powder curing furnace 6, and a forced cooling device 7, which are sequentially connected to the conveyor. The moisture drying furnace 4 is connected to a paint booth 9 at the rear end of the discharge port, allowing workpieces 16 to be sprayed with powder or painted according to process requirements. The spraying device 3, the powder curing furnace 6, and the paint booth 9 are connected to a wastewater treatment device 8 via pipelines. The shot blasting equipment 2 comprises a shot blasting wheel connected to a longitudinal spiral, a transverse spiral, and an elevator, with a separator installed at the rear ends of the longitudinal spiral, transverse spiral, and elevator. The spraying equipment 3 comprises a degreasing tank, a first water washing tank, a second water washing tank, and a spraying tank, each equipped with an automatic dosing device and a tank liquid detection device. The moisture drying furnace 4 comprises a gas heating device and a hot air circulation device. The forced cooling device 7 is an exhaust device. The wastewater treatment equipment 8 comprises a flocculation and sedimentation chamber, a carbon sand filter, and a plate and frame filter press 10. Workpieces 16 are transported to the shot blasting equipment. Within the shot blasting chamber, the shot blasting wheel ejects shot at high speed onto the surface of the workpiece 16, removing impurities such as scale and rust. The cleaned shot is transported to the separator via the longitudinal spiral, transverse spiral, and elevator, where qualified shot is separated and recycled, while impurities are discharged. After shot blasting, the workpiece 16 enters the spraying equipment 3, where it undergoes a series of degreasing, first water washing, second water washing, and three spraying steps to remove oil and impurities from the workpiece 16's surface. The spray liquid is then circulated in the liquid tank, with an automatic dosing device and tank liquid detection device maintaining the tank liquid's concentration and performance. After treatment in the spraying equipment 3, the workpiece 16 enters the moisture drying furnace 4, where a gas heating system and hot air circulation system are used to dry out the moisture from the workpiece 16's surface. A temperature control system precisely controls the furnace temperature to ensure effective drying. Depending on the process requirements, the workpiece 16 can enter the powder spraying equipment for powder coating or the paint booth 9 for painting. In the powder spraying equipment, the powder is fully fluidized in the powder box of the powder supply center. A powder pump creates a siphon effect and delivers the powder through the powder hose to the spray gun. The powder passes through the corona area of ​​the spray gun electrode, where it is charged with static electricity and adsorbed to the grounded workpiece surface. In the paint booth 9, the paint mist is treated through a filtration system to ensure that the exhaust air meets environmental requirements. After powder coating, the workpiece enters the powder curing furnace 6. A gas-fired heating system and hot air circulation system solidify the powder on the surface of the workpiece 16, forming a durable coating. A temperature control system precisely controls the temperature within the furnace to ensure a consistent curing effect. The cured workpiece enters a forced cooling facility, where forced cooling is achieved through the supply and exhaust air systems, rapidly reducing the temperature of the workpiece 16 to below the specified temperature. The cooled workpiece 16 is then unloaded from the conveyor 1 through the unloading area, completing the entire surface treatment and coating process.

[0035] Example 2:

[0036] See also Figure 2-Figure 5The filter plates 11 of the plate and frame filter press 10 are provided with a set of symmetrically arranged scraper assemblies 12, including scrapers 121 and springs 122. The two scrapers 121 are symmetrically slidably arranged on the upper and lower sides of the material opening 111 of the filter plate 11. One end of the spring 122 is fixedly connected to the scraper 121, and the other end is fixedly connected to the filter plate 11. The sewage suspension is introduced from the material opening 111 of the filter plate and enters the chamber between the two filter plates 11 for squeezing and filtering. During the liquid inflow process, the suspension with increasing volume pushes the two scrapers 121 to move relative to each other and stretches the spring 122. When the filtration is completed, the two filter plates 11 are separated by the external components. After the filter cake is unloaded from the chamber, the two scrapers 121 are reset to their initial positions under the drive of the spring 122, thereby scraping off the sludge attached to the filter cloth 112, thereby cleaning the filter cloth 112, so as to reduce the subsequent cleaning of the filter cloth 112.

[0037] A knocking assembly 13 is provided in the filter plate 11, and the knocking assembly 13 includes a rack 131 and a cam 132. The rack 131 is slidably provided in the filter plate 11, and the cam 132 is rotatably connected to the rack 131. The cam 132 is provided in cooperation with the filter cloth 112 in the filter plate 11. It should be noted that a tooth groove is provided in the filter plate 11, and the cam 132 is coaxially fixedly connected with a gear (not shown in the figure). The gear is provided in the tooth groove and meshes with the tooth groove, so that when the rack 131 moves up and down, the gear rotates to drive the cam 132 to rotate; it also includes a mechanism for driving The drive assembly 14 that moves the movable rack 131 includes a gear 141, a ratchet 142, and a pawl 143. Gear 141 is rotatably mounted at one end of the scraper 121 and meshes with the rack 131. The ratchet 142 is coaxially connected to gear 141 and is fitted with an energy-storage torsion spring. The pawl 143 is located within the filter plate 11 and is fitted with a first return torsion spring to reset the ratchet 143 after the removal of external force. The pawl 143 is coaxially connected to the ratchet 142 and is coaxially connected to a knob. When the scraper 121 is pushed by the suspension, gear 141 and ratchet 142 rotate, causing the energy-storage torsion spring within the ratchet 142 to deform and store energy. Simultaneously, gear 141 drives the rack 131 to move, thereby rotating the cam 132. When the scraper 121 moves to its maximum stroke, the ratchet 142 is restricted by the pawl 143, causing the internal energy storage torsion spring to remain in a charged state, and the rack 131 moves to its maximum stroke. After the two filter plates 11 are removed, the pawl 143 is rotated by the knob. After the ratchet 142 is no longer restricted by the pawl 143, it drives the gear 141 to rotate, thereby resetting the rack 131. During the resetting process of the rack 131, the cam 132 rotates and collides with the filter cloth 112, causing the mud cake on the filter cloth 112 to separate from the filter cloth 112, thereby preventing the filter cake from adhering too tightly to the filter cloth 112 and making it difficult to remove the filter cake from the cavity. When the mud cake and the filter cloth 112 are loose, the filter cake is removed from the filter plate 11, and the scraper 121 is reset by the spring 122 to scrape and clean the mud adhering to the filter cloth 112.

[0038] It also includes a spray assembly 15 arranged in the filter plate 11, the spray assembly 15 includes a pressure water pump 151 and a water storage chamber 152, the water inlet end of the pressure water pump 151 is connected to the water storage tank through a pipe, and the water outlet end of the pressure water pump 151 is connected to the water storage chamber 152 through a pipe; it also includes a turntable 153 and a knocking ball 154, the turntable 153 is coaxially fixedly connected to the ratchet 142, the knocking ball 154 is slidably arranged in the turntable, the knocking ball 154 is connected to a return spring 155, the free end of the return spring 155 is fixedly connected to the turntable, and the knocking ball 154 is cooperated with the pressure water pump 151; the water storage chamber 152 is connected to a spray pipe, the spray pipe is connected to several nozzles 156, and a valve 157 is provided on the spray pipe. A return torsion spring is passed through the handle of the valve 157 and the connection point of the valve 157, and the handle of the valve 157 is cooperated with the rack 131. When the ratchet 142 rotates and drives the turntable 153 to rotate synchronously, the knocking ball 154 in the turntable 153 is thrown out of the turntable 153 by the centrifugal force of the turntable 153, thereby knocking and pressing the water pump 151, so that the water in the water tank is pumped into the water storage chamber 152 and flows out to the filter cloth 112 through the spray pipe. When the rack 131 returns to its initial position, the mud cake on the filter cloth 112 has been knocked and vibrated by the cam 132 to be loosened. After the plate 11 is removed, the scraper 121 is reset to its initial position. At this time, the rack 131 has been reset to its initial position. The rack 131 pushes the handle of the valve 157 to rotate, so that the liquid in the spray pipe flows out and is sprayed onto the filter cloth 112 through the nozzle 156. The filter cloth 112 is cleaned with the cooperation of the water flow and the scraper 121, which makes it easier for the scraper 121 to better hang out the sludge remaining on the filter cloth 112, and the cleaning effect of the filter cloth 112 is better.

[0039] The above is only an embodiment of the present invention, and the commonly known specific structures and characteristics of the scheme are not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, and these should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
