Description

[Technical field]

[0001] The invention belongs to the technical field of chain saw processing, and in particular relates to an online high-temperature burning and cleaning device based on a hanging chain spray hook. [Background technology]

[0002] The working principle of product spraying is to charge the plastic powder through high-voltage electrostatic equipment, and then spray it onto the surface of the workpiece under the action of the electric field. Specific process: Plastic powder is fed into the spray gun through compressed air, and high-voltage static electricity is generated at the front end of the spray gun to form an electrostatic field. After passing through the electrostatic field, the paint powder carries a charge and is adsorbed to the surface of the workpiece by the electrostatic force. As the powder accumulates, the charge gradually increases. When a certain thickness is reached, the later powder will be repelled by the powder already attached to the surface of the workpiece and stop adsorbing, thus forming a powder coating of a certain thickness. The main reason for affecting the spraying effect or adhesion is that the accumulation of powder affects the conductivity, thereby affecting the adsorption of powder. Therefore, if the hanger needs to be kept clean, the powder on the hanger must be cleaned.

[0003] Conventional hook deplasticization method in the prior art:

[0004] Centralized high-temperature furnace sintering cleaning: This is the most widely used and effective cleaning method. The high temperature environment causes the resin and additives in the coating to undergo carbonization reaction, and then the carbonized coating is powdered with water mist, thereby achieving effective cleaning of the hanger surface;

[0005] Chemical swelling cleaning: After soaking or brushing the hanger with paint stripper, its ingredients can quickly penetrate the coating, softening and swelling the paint film, and then naturally falling off. Most common paint strippers on the market are acidic, containing organic solvents, co-solvents, activators, thickeners and volatile inhibitors. The method of use is simple: soak the workpiece in the paint stripper for 5 to 20 minutes, the old paint film will swell strongly, and then fall off naturally. After that, just use high-pressure water to remove the remaining paint flakes on the surface, and rinse with clean water;

[0006] Sandblasting: Sandblasting is excellent in removing coatings from the surface of hangers, especially for hangers with uneven coating thickness or complex structures. It is necessary to accurately adjust the parameters such as sandblasting pressure, sandblasting medium selection and particle size, spray gun movement speed and angle to ensure that the paint film can be completely removed without damaging the fine structure and surface roughness of the hanger;

[0007] Shot blasting paint stripping machine: The motor drives the impeller to rotate at high speed to throw fine steel shots at the hanger, which rotates 360 degrees continuously in the cabin to clean the paint on the hanger. This method is purely physical and there is no emission of pollutants. In addition, the paint knocked off during the cleaning process will form dust, which will be filtered and collected in an independent dust removal chamber.

[0008] The solvent method for large-scale processing has no advantages in terms of environmental protection and labor intensity. For environmental protection, heat treatment furnaces are basically used. Conventional hook powder removal and cleaning processes basically use centralized heat treatment combustion methods for environmental protection and convenience. The specific processing flow is: the hook is replaced once per shift (upper and lower hangers, 2 people for 2 hours) → centralized vacuum heat treatment furnace cleaning (550℃5h) → cooling (2h) → water cleaning (1h) → transfer to the workshop, but it basically takes dozens of hours to complete the processing. [Summary of the invention]

[0009] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide an online high-temperature cleaning equipment based on a hanging chain spray hook, so as to solve the problem that the prior art uses a centralized high-temperature furnace for sintering and a high-pressure water washing for deplasticizing the spray hook separately, and requires upper and lower hangers and a transfer workshop, resulting in low cleaning efficiency.

[0010] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0011] Online high temperature cleaning equipment based on hanging chain spray hook, including:

[0012] A hanging chain line, on which a spray hook is hung, and the running path of the hanging chain line passes through a high-voltage electrostatic spraying device, a cleaning furnace and a cleaning machine;

[0013] A cleaning furnace, the cleaning furnace comprising a flame-spraying end component and a flame-blocking end component arranged on opposite sides of a running path of a suspension chain line, the flame-spraying end component is provided with a flame-spraying torch distributed along the running path of the suspension chain line, the flame-blocking end component can be opened and closed relative to the flame-spraying end component when operated, the flame-blocking end component is relatively closed with the flame-spraying end component when the cleaning furnace is cleaning, the flame-spraying torch sprays flame toward the flame-blocking end component when the cleaning furnace is cleaning, and the high temperature generated by the flame at the joint between the flame-spraying end component and the flame-blocking end component causes carbonization of the coating on the surface of the spray hook;

[0014] A cleaning machine is provided with a high-pressure nozzle, which sprays water mist to the spray hook to powderize the carbonized coating, thereby cleaning the surface of the spray hook.

[0015] Preferably, a slide rail is provided below the flame-blocking end component, and a roller is provided at the bottom of the flame-blocking end component, and the roller cooperates with the slide rail.

[0016] Preferably, a limiting component is provided between the flame-blocking end component and the slide rail, and the limiting component is used to limit the movement of the flame-blocking end component relative to the slide rail.

[0017] Preferably, the limiting component includes a limiting seat fixed on the slide rail and a limiting hook hinged to the limiting seat, the roller is connected to the roller seat through a roller shaft, one end of the roller shaft is provided with a limiting groove protruding from the outside of the roller seat, and the limiting hook cooperates with the limiting groove.

[0018] Preferably, a handle is provided on the side of the flame-blocking end component facing away from the flame-emitting end component.

[0019] Preferably, the flame-blocking end component is provided with a flame-blocking portion, and the flame-blocking portion is provided with a flame-blocking plate.

[0020] Preferably, a hanging chain support frame is provided on the top of the flame-spraying end component.

[0021] Preferably, the cleaning furnace is provided with a dust cover above the joint portion between the flame-spraying end component and the flame-blocking end component, and the dust cover is connected to the exhaust gas treatment equipment.

[0022] Preferably, the cleaning machine is provided with a cleaning water recovery system for recovering cleaning water, the cleaning water recovery system comprises a filtering water pool, and the high-pressure nozzle is connected to the filtering water pool via a water supply pipe.

[0023] Preferably, the cleaning water recovery system also includes a water receiving trough and a return water trough. The water receiving trough is arranged below the spray hook to receive the cleaning water after cleaning the spray hook. The return water trough is arranged below the water receiving trough to receive the cleaning water falling from the water receiving trough and transport the cleaning water to the filter pool.

[0024] The present invention adopts the above technical solution and has the following beneficial effects:

[0025] 1. In order to overcome the centralized heat treatment combustion method, it is necessary to put up and down hangers and transfer between the spraying workshop and the heat treatment workshop, which has the disadvantages of high labor intensity and low processing efficiency. The online combustion and cleaning process is adopted, that is, relying on the existing hanging chain line, the spray hooks that need to be de-plasticized are directly passed through the burning and cleaning furnace and the cleaning machine in turn. When the spray hooks pass through the burning and cleaning furnace, they are sprayed and burned. The high temperature generated quickly burns the powder attached to the hooks. Then, they are washed by the cleaning machine under high pressure to completely remove the powder on the hooks. After that, the cleaned hooks continue to run online. Since high-temperature burning and high-pressure cleaning are processed online, there is no need for upper and lower hangers and transfer, which reduces labor intensity and improves efficiency.

[0026] Since the online high-temperature cleaning equipment is operated intermittently, that is, the powder coating is cleaned only when it accumulates to a certain thickness and affects the spraying effect or adhesion, but the suspension chain line is kept in a continuous operation state, in order to avoid the cleaning furnace from affecting the normal operation of the suspension chain line. The cleaning furnace includes a flame spraying end component and a flame blocking end component arranged on opposite sides of the running path of the suspension chain line, wherein the flame blocking end component can be opened and closed relative to the flame spraying end component when operated, and the flame blocking end component is relatively closed with the flame spraying end component when the cleaning furnace is cleaning, and is relatively open with the flame spraying end component when not cleaning. In the closed state, the flame blocking end component can shield the flame sprayed by the flame spraying torch, on the one hand to prevent the flame from causing harm, and on the other hand to concentrate the heat in the area between the flame spraying end component and the flame blocking end component, thereby facilitating the formation of high temperature and promoting the carbonization reaction of the resin and additives in the coating.

[0027] 2. In order to facilitate the opening and closing of the flame-blocking end component relative to the flame-spraying end component when it is operated, a slide rail is provided below the flame-blocking end component, and a roller is provided at the bottom of the flame-blocking end component, and the roller cooperates with the slide rail. In this way, a single worker can easily operate the flame-blocking end component to achieve the opening and closing of the flame-spraying end component relative to the flame-spraying end component when it is operated. Of course, it is also ensured that the positions of the flame-blocking end component and the flame-spraying end component are fixed perpendicular to the sliding direction to avoid relative misalignment. In addition, a handle is provided on the side of the flame-blocking end component facing away from the flame-spraying end component for easy operation.

[0028] 3. A limiting component is provided between the flame-blocking end component and the slide rail, and the limiting component is used to limit the movement of the flame-blocking end component relative to the slide rail, that is, the flame-blocking end component can be kept relatively fixed regardless of being in the open or closed state.

[0029] 4. In order to treat the waste gas and smoke generated, a dust cover is provided above the cleaning furnace. The dust cover is connected to a dust removal device, such as for dust treatment and other harmful gas treatment. After the treatment, the dust is discharged into the atmosphere to avoid pollution to the environment.

[0030] 5. The cleaning machine is provided with a cleaning water recovery system for recovering cleaning water. The cleaning water recovery system comprises a filtering water pool. The high-pressure nozzle is connected to the filtering water pool through a water supply pipe, so that the cleaning water can be recycled and water can be saved.

[0031] Therefore, the present invention can efficiently and timely process the coating of the spray hook online, reduce the power consumption of the heat treatment furnace, avoid the transfer of the upper and lower hangers between the cleaning furnace and the cleaning machine, and avoid high-intensity upper and lower hangers and transportation work.

[0032] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

[Specific implementation method]

[0042] The technical solutions of the embodiments of the present invention are explained and described below in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0043] Those skilled in the art will appreciate that, in the absence of conflict, the features in the following embodiments and implementations may be combined with each other.

[0044] The terms used in the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. For example, the words "upper", "lower", "left", "right", etc., which indicate the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device / element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0045] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0046] In order to overcome the disadvantages of centralized heat treatment combustion mode, upper and lower hangers and transfer between the spraying workshop and the heat treatment workshop are required, which has high labor intensity and low processing efficiency. Figures 1 to 7 As shown, an embodiment of the present invention provides an online high-temperature cleaning device based on a hanging chain spray hook, comprising:

[0047] A suspension chain 1, on which a spray hook 11 is suspended, and the running path of the suspension chain passes through a high-voltage electrostatic spraying device, a cleaning furnace 2 and a cleaning machine 3;

[0048] The cleaning furnace 2 comprises a flame-spraying end component 21 and a flame-blocking end component 22 arranged on opposite sides of the running path of the suspension chain line. Here, it is assumed that the flame-spraying end component 21 and the flame-blocking end component 22 are located in the left-right direction. The flame-spraying end component is provided with a flame-spraying torch 211 distributed along the running path of the suspension chain line. The flame-blocking end component can be opened and closed relative to the flame-spraying end component when operated. The flame-blocking end component is relatively closed with the flame-spraying end component when the cleaning furnace is cleaning. The flame-spraying torch sprays flame toward the flame-blocking end component when the cleaning furnace is cleaning. The high temperature generated by the flame at the joint between the flame-spraying end component and the flame-blocking end component causes the coating on the surface of the spray hook to be carbonized.

[0049] The cleaning machine 3 is provided with a high-pressure nozzle 31, which sprays water mist to the surface of the spray hook to powderize the carbonized coating, thereby cleaning the surface of the spray hook. Figure 2As shown, the water mist sprayed by the high-pressure nozzle covers the bottom of the spray hook, that is, the hooked part, so as to clean the part that needs to be de-plasticized to avoid affecting the spraying effect or adhesion.

[0050] Among them, the hanging chain line 1 is a common setting in the high-voltage electrostatic spraying process. A spray hook 11 is hung on the hanging chain line. The parts that need to be sprayed, such as a chain saw guide plate, are hooked on the spray hook 11. The running path of the hanging chain line passes through the high-voltage electrostatic spraying equipment to complete the spraying of the parts. This embodiment relies on the existing hanging chain line to directly pass the spray hook that needs to be de-plasticized through the burning and cleaning furnace and the cleaning machine in turn. When the spray hook runs through the burning and cleaning furnace, it is sprayed and burned. The high temperature generated quickly burns the powder attached to the hook, and then passes through the cleaning machine for high-pressure cleaning to completely remove the powder on the hook. After that, the hook after cleaning continues to run online. Since high-temperature burning and high-pressure cleaning are processed online, there is no need for upper and lower hangers and transfer, which reduces labor intensity and improves efficiency.

[0051] The positions of the burn-cleaning furnace and the cleaning machine relative to the running path of the suspension chain are fixed. The online high-temperature burn-cleaning equipment is intermittently operated. When the high-voltage electrostatic spraying process is normally carried out, the burn-cleaning furnace and the cleaning machine are not operated. If the powder coating accumulates to a certain thickness and affects the spraying effect or adhesion, it needs to be cleaned, and then the burn-cleaning furnace and the cleaning machine are turned on. Since the suspension chain always maintains a continuous operation state, in order to avoid the burn-cleaning furnace from affecting the normal operation of the suspension chain (after the spraying is completed, the hook continues to run online and will run to the next process), the flame blocking end component can be opened and closed relative to the flame spraying end component when operated. The flame blocking end component is relatively closed with the flame spraying end component when the burn-cleaning furnace is burning and cleaning, and is relatively opened with the flame spraying end component when it is not burning and cleaning. In the closed state, the flame blocking end component can block the flame sprayed by the flame spraying torch, on the one hand to prevent the flame from causing harm, and on the other hand to concentrate the heat in the area between the flame spraying end component and the flame blocking end component, thereby facilitating the formation of high temperature and promoting the carbonization reaction of the resin and additives in the coating.

[0052] In some embodiments, a slide rail 23 is provided below the flame-blocking end component 22, and the slide rail extends along the sliding direction of the flame-blocking end component. A roller 222 is provided at the bottom of the flame-blocking end component, and the roller 222 cooperates with the slide rail 23. In this way, it is more labor-saving during operation, and a single worker can easily operate it, which facilitates the flame-blocking end component to be opened and closed relative to the flame-spraying end component when it is operated. Of course, it also ensures that the positions of the flame-blocking end component and the flame-spraying end component are fixed perpendicular to the sliding direction to avoid relative misalignment. Specifically, two slide rails 23 can be arranged side by side, and a cylindrical portion with a cylindrical cross-section is provided at the top of the slide rail, and a roller groove is provided on the roller to cooperate with the cylindrical portion.

[0053] Furthermore, a limiting component 24 is provided between the flame-blocking end component 22 and the slide rail 23, and the limiting component 24 is used to limit the movement of the flame-blocking end component relative to the slide rail. The limiting component includes a limiting seat 241 fixed on the slide rail, and a limiting hook 242 hinged to the limiting seat. The roller is connected to the roller seat through a roller shaft, and one end of the roller shaft is provided with a limiting groove 2221 protruding from the outside of the roller seat, and the limiting hook 242 cooperates with the limiting groove 2221. In the open and closed states, in order to keep the flame-blocking end component relatively fixed, the limiting hook 242 cooperates with the limiting groove 2221. If the flame-blocking end component 22 needs to be moved, the limiting hook 242 is pulled upward, and the limiting hook 242 is disengaged from the limiting groove 2221, and the flame-blocking end component 22 can be moved. Since the limit seat 241 is fixed and only one is provided, in the open state, the roller away from the flame end component is farther away from the limit seat, and in the closed state, the roller close to the flame end component is farther away from the limit seat. Correspondingly, hook grooves 243 are provided on opposite sides of the free end of the limit hook 242, so that in the open state, the first hook groove cooperates with the limit groove of the roller close to the flame end component, and in the closed state, the second hook groove cooperates with the limit groove of the roller away from the flame end component.

[0054] Specifically, the flame torch 211 of the flame end component is connected to the natural gas pipeline 212. The flame torch 211 burns natural gas for heating, which is more environmentally friendly, and the combustion temperature meets the heating requirements. The flame end component is provided with refractory bricks, which can withstand high temperatures and provide heat insulation to prevent the shell temperature of the flame end component from being too high. The upper part of the flame blocking end component is provided with a flame blocking portion 221 that is recessed away from the flame end component. The flame blocking portion is provided with a flame blocking plate. The flame blocking portion is directly opposite to the flame spraying position of the flame torch 211 and is relatively recessed away from the flame end component, which is conducive to the suspension of the guide plate to avoid interference. The flame blocking plate is made of high-temperature resistant steel plate.

[0055] In addition, a handle 223 is provided on the side of the flame blocking component 22 facing away from the flame ejection end component to facilitate opening and closing operations and to pull the flame blocking end component to move.

[0056] Specifically, the top of the flame spraying end component is provided with a suspension chain wire support frame 25. The suspension chain wire passes through the cleaning furnace 2 and is connected to the suspension chain wire support frame 25.

[0057] In addition, the cleaning furnace 2 is provided with a dust cover 26 above the joint between the flame-spraying end component and the flame-blocking end component. The top of the dust cover 26 is provided with a connection interface and is connected to exhaust gas treatment equipment, such as dust treatment and other harmful gas treatment. After treatment, the exhaust gas is discharged into the atmosphere to avoid pollution to the environment.

[0058] The structure of the cleaning machine can refer to the prior art. In addition, in order to realize the recycling of cleaning water and save water, the cleaning machine 3 is provided with a cleaning water recovery system for recovering cleaning water. Specifically, the cleaning water recovery system includes a filter pool 33, the high-pressure nozzle 31 is connected to the filter pool through a water supply pipe, and the water supply pipe is connected to a high-pressure water pump 32. The high-pressure water pump extracts the cleaning water filtered in the filter pool and sprays water mist to the surface of the spray hook through the high-pressure nozzle to powderize the carbonized coating.

[0059] Furthermore, the cleaning water recovery system also includes a water receiving tank 34 and a water return tank 36. The water receiving tank 34 is arranged below the spray hook to receive the cleaning water after cleaning the spray hook. The water return tank 36 is arranged below the water receiving tank to receive the cleaning water falling from the water receiving tank and transport the cleaning water to the filter pool. The water receiving tank is connected to the water receiving cylinder 35. When the cleaning machine is running, the water receiving cylinder 35 sends the water receiving tank to the water receiving position. When it is not running, the water receiving cylinder 35 drives the water receiving tank back to avoid affecting the normal operation of the suspension chain line.

[0060] The above is only a specific embodiment of the invention, but the protection scope of the invention is not limited thereto. Those skilled in the art should understand that the invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the invention will be included in the scope of the claims.
