Abstract
Description
Technical Field
[0001] This utility model relates to the field of spraying technology, specifically a Raney nickel uniform spraying device. Background Technology
[0002] Raney nickel is a fine gray powder whose main component is nickel, with a small amount of aluminum. It is an important industrial catalyst. In the ceramic production and processing process, by spraying Raney nickel onto the ceramic surface, the ceramic surface can be endowed with catalytic function, enabling it to play a catalytic role in specific chemical reactions, thereby expanding the application fields of ceramics.
[0003] The existing Raney nickel uniform spraying device mainly consists of a housing, a spraying mechanism, and a rotating mechanism. When spraying Raney nickel powder onto the ceramic surface, the ceramic to be processed is first placed into the housing. Then, the pump is started, which draws out the Raney nickel powder in the storage tank through the extraction pipe and conveys it into the nozzle through the delivery pipe. Finally, the powder is sprayed onto the ceramic surface through the nozzle. At the same time, the motor is started to drive the rotating disk to rotate, which in turn causes the ceramic to rotate as well, thus enabling all-round spraying operations on the ceramic surface.
[0004] Existing Raney nickel uniform spraying devices often have fixed nozzle positions, making it impossible to adjust the distance between the nozzle and the workpiece as needed. This makes them unsuitable for spraying workpieces of different sizes. Improper nozzle distance settings can affect key properties of the coating, such as adhesion, hardness, and wear resistance. A fixed distance may lead to unstable coating quality and poor spraying results. Therefore, a Raney nickel uniform spraying device is proposed to address these issues. Utility Model Content
[0005] To overcome the shortcomings of existing technologies and solve the problems mentioned in the background art, this utility model proposes a Raney nickel uniform spraying device.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A Raney nickel uniform spraying device of this utility model includes a housing. First limiting grooves are provided on the top and bottom inner walls of the housing. First sliders are provided in both first limiting grooves. A first hollow tube connects the two first sliders. Multiple nozzles are connected to the first hollow tube. Each nozzle is equipped with a first one-way valve. A fixing block is installed on one side of each of the upper and lower first limiting grooves. A threaded rod is rotatably mounted on the fixing block and the side wall of the housing, and the threaded rod passes through the first slider. A pulley is fitted onto one end of each of the two threaded rods. A conveyor belt is fitted onto the outer surface of the two pulleys. A support plate is installed on one bottom side of the housing. A first motor is mounted on the support plate. The output end of the first motor is connected to one end of the threaded rod at the bottom. When spraying Raney nickel powder onto ceramic surfaces of different sizes, in order to adjust the optimal spraying distance, a nozzle adjustment mechanism is set up. The first motor is started, causing the pulley and threaded rod located below to rotate. With the cooperation of the conveyor belt, the pulley and threaded rod located above also rotate synchronously, forcing the first slider to move within the first limiting groove. The first slider drives the first hollow tube and the nozzle to rotate accordingly. Thus, the distance between the nozzle and the ceramic can be adjusted according to different ceramic sizes to achieve the optimal spraying distance. By precisely adjusting the position of the nozzle, the uniformity of the coating can be ensured, thus guaranteeing the spraying quality.
[0007] Preferably, a storage tank is installed on one side of the top of the housing, and a pump body is mounted on the storage tank. The input port of the pump body is connected to a suction pipe, which is located inside the storage tank. The output port of the pump body is connected to a delivery hose, and the other end of the delivery hose is connected to a first hollow tube. When spraying Raney nickel powder, the pump body operates to transport the Raney nickel powder in the storage tank into the first hollow tube through the delivery hose. Finally, the Raney nickel powder is sprayed onto the ceramic surface through the nozzle. By spraying Raney nickel powder onto the ceramic surface, the metallic properties of Raney nickel can be utilized to enhance the bonding force between the ceramic and the metal or other substrate materials, giving the ceramic excellent properties.
[0008] Preferably, the top and bottom inner walls of the housing are provided with second limiting grooves, and the first and second limiting grooves are located on the two sides of the housing respectively. A second slider is provided in each of the two second limiting grooves, and a second hollow tube is fixedly connected between the two second sliders. Multiple nozzles are connected to the second hollow tube, and each nozzle is equipped with a second one-way valve. Two first pneumatic cylinders are installed on one side wall of the housing. The actuating end of each of the two first pneumatic cylinders is equipped with a first pneumatic rod, and the other end of the first pneumatic rod is fixedly connected to the second slider. After the ceramic coating is completed, the coating on its surface needs to be dried. To achieve a better drying effect, the distance between the nozzle and the ceramic surface needs to be precisely adjusted. By setting a nozzle adjustment mechanism, the first pneumatic cylinder is activated, causing the first pneumatic rod to push the second slider to move within the second limiting groove. The second slider drives the second hollow tube and the nozzle to move, adjusting the nozzle position to the optimal drying distance. By precisely adjusting the distance between the nozzle and the ceramic surface, the uniformity and consistency of the drying effect can be ensured, achieving the best drying effect.
[0009] Preferably, a housing is installed on the other side of the top of the box, a heating wire is installed inside the housing, a blower is installed inside the housing, a flexible hose channel is connected between the housing and the second hollow tube, and a dustproof net is installed inside the air inlet pipe of the housing. After the nozzle is adjusted, during drying, the blower operates, and with the cooperation of the heating wire, the heated high-temperature gas is blown through the nozzle to the ceramic surface, thereby enabling the coating on the ceramic surface to dry and cure quickly.
[0010] Preferably, a second motor is installed at the bottom of the housing, and a rotating disk is installed at the output end of the second motor. A groove is formed on the rotating disk, and a bidirectional lead screw is rotatably installed within the groove. Two movable blocks are sleeved on the bidirectional lead screw, and the movable blocks are positioned within the groove. A clamping plate is fixed to the top of each movable block. A motor is installed on the outer circumference of the rotating disk, and the output end of the motor is connected to one end of the bidirectional lead screw. A second pneumatic cylinder is installed at the top of the housing, and a second pneumatic rod is fitted to the actuating end of the second pneumatic cylinder. A pressing plate is rotatably installed at the bottom end of the second pneumatic rod. When spraying Raney nickel powder onto a ceramic surface, the ceramic to be processed needs to be fixed. The motor is started, causing the bidirectional lead screw to rotate, which in turn moves two movable blocks within the groove. The two movable blocks drive the clamping plates closer together, thereby clamping and fixing the bottom of the ceramic. Then, the second pneumatic cylinder is activated, causing the pressing plate to move down to contact the top of the ceramic, thereby pressing and fixing the ceramic. Through the dual operation of clamping and pressing, the stability of the ceramic fixing can be significantly improved. This dual fixing method not only ensures the stability of the ceramic position during the spraying process, but also helps to improve the uniformity and quality of the spraying.
[0011] Preferably, the port of the housing is hinged with a sealed door, and the sealed door is provided with an observation window. When using the device, the observation window facilitates observation of the internal condition of the housing and timely understanding of the ceramic coating status.
[0012] The advantages of this utility model are:
[0013] 1. In order to adjust the optimal spraying distance when spraying Raney nickel powder onto ceramic surfaces of different sizes, this utility model sets up a nozzle adjustment mechanism. The first motor is started, causing the pulley and threaded rod located below to rotate. With the cooperation of the conveyor belt, the pulley and threaded rod located above also rotate synchronously, forcing the first slider to move within the first limiting groove. The first slider drives the first hollow tube and the nozzle to rotate accordingly. Thus, the distance between the nozzle and the ceramic can be adjusted according to the different sizes of ceramics to achieve the optimal spraying distance. By precisely adjusting the position of the nozzle, the uniformity of the coating can be ensured, thus guaranteeing the spraying quality.
[0014] 2. After the ceramic coating of this utility model is completed, the coating on its surface needs to be dried. In order to achieve a better drying effect, it is necessary to precisely adjust the distance between the nozzle and the ceramic surface. By setting a nozzle adjustment mechanism, the first pneumatic cylinder is activated, which pushes the second slider to move in the second limit groove. The second slider drives the second hollow tube and the nozzle to move, so that the nozzle position is adjusted to the optimal drying distance. By precisely adjusting the distance between the nozzle and the ceramic surface, the uniformity and consistency of the drying effect can be ensured, so as to achieve the best drying effect.

[0030] Working Principle: Existing Raney nickel uniform spraying devices often have a fixed nozzle 5 position, making it impossible to adjust the distance between the nozzle 5 and the workpiece as needed. This makes them unsuitable for spraying workpieces of different sizes. Improper nozzle 5 distance settings can affect key properties of the coating, such as adhesion, hardness, and wear resistance. A fixed distance can lead to unstable coating quality and poor spraying results. Therefore, a Raney nickel uniform spraying device is proposed to address these issues. When spraying Raney nickel powder onto ceramic surfaces of different sizes, to adjust the optimal spraying distance, a nozzle 5 adjustment mechanism is set up. The first motor 11 is started, causing the lower pulley 8 and threaded rod 7 to rotate. With the cooperation of the conveyor belt 9, the upper pulley 8 and threaded rod 7 also rotate synchronously, forcing the first... The slider 3 moves within the first limiting groove 2, causing the first hollow tube 4 and the nozzle 5 to rotate accordingly. This allows the distance between the nozzle 5 and the ceramic to be adjusted according to different ceramic sizes, achieving the optimal spraying distance. By precisely adjusting the position of the nozzle 5, the uniformity of the coating can be ensured, guaranteeing the spraying quality. After the nozzle 5 position is adjusted, when spraying Raney nickel powder, the pump body 13 operates to extract the Raney nickel powder in the storage tank 12 through the extraction pipe and transport it into the first hollow tube 4 through the delivery hose 14. Finally, the nozzle 5 sprays the Raney nickel powder onto the ceramic surface. By spraying Raney nickel powder onto the ceramic surface, the metallic properties of Raney nickel can be utilized to enhance the bonding force between the ceramic and the metal or other substrate materials, giving the ceramic excellent performance.
[0031] After the ceramic coating is applied, the surface coating needs to be dried. To achieve a better drying effect, the distance between the nozzle 18 and the ceramic surface needs to be precisely adjusted. By setting the nozzle 18 adjustment mechanism, the first pneumatic cylinder 19 is activated, causing the first pneumatic rod 20 to push the second slider 16 to move within the second limiting groove 15. The second slider 16 drives the second hollow tube 17 and the nozzle 18 to move, adjusting the position of the nozzle 18 to the optimal drying distance. By precisely adjusting the distance between the nozzle 18 and the ceramic surface, the uniformity and consistency of the drying effect can be ensured, achieving the best drying effect. After the nozzle 18 is adjusted, during drying, the blower 24 operates, and with the cooperation of the heating wire 23, the heated high-temperature gas is blown onto the ceramic surface through the nozzle 18, thereby enabling the coating on the ceramic surface to dry and cure quickly.
