Description

Technical Field

[0001] The utility model relates to the technical field of the preparation of zinc-aluminum coating liquid, in particular to a feeding device for the preparation of zinc-aluminum coating liquid which is convenient for cleaning and replacement. Background Technique

[0002] Zinc-aluminum coating liquid is used for zinc-aluminum coating operation, also known as zinc-aluminum based coating, which is a new type of metal heavy anti-corrosion coating technology. It is applicable to the metal anti-corrosion treatment of thin-walled metal components such as color steel houses, cable trays, and large transformer radiators, and can replace metal anti-corrosion technologies such as dacromet, hot-dip galvanizing, and electro-galvanizing.

[0003] Zinc-aluminum coating uses a chromium-free coating composed of flaky zinc powder, flaky aluminum powder, and an organic carrier to brush or spray the metal surface. The coating process does not require heat curing, has a low process cost, and has no environmental pollution. The dry film metal content of the coating is greater than 70%, and the equivalent zinc content is greater than 90% (calculated by replacing aluminum powder with zinc powder of equal volume), making the anti-corrosion coating conductive, with an electrode potential of -980mv, which has a cathodic protection effect on steel components. The ultra-fine flaky zinc powder and aluminum powder used in zinc-aluminum coating have an average thickness of 100 nanometers and an average diameter of less than 10 microns, forming a comprehensive shielding effect with the modified epoxy resin, hindering and extending the infiltration path of gas and liquid, providing good shielding protection for steel components, and at the same time reducing the effective thickness of the coating. The heat conduction effect of flaky zinc-aluminum powder makes the heat conductivity of its coating better than that of traditional anti-corrosion coatings.

[0004] In a conventional feeding device, the container for storing materials is structurally fixed by a frame, and it is difficult to flexibly disassemble the inside of the overall structure as needed for the operators to carry out maintenance and cleaning. At the same time, due to its relatively integrated design of its own structure, it is difficult for the operators to normally and quickly disassemble or replace it.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a feeding device for the preparation of zinc-aluminum coating liquid which is convenient for cleaning and replacement is proposed. Content of the Utility Model

[0006] The purpose of the utility model is to provide a feeding device for the preparation of zinc-aluminum coating liquid which is convenient for cleaning and replacement, so as to solve the problems raised in the above background technique.

[0007] To achieve the above object, the present utility model provides the following technical solutions: A feeding device for preparing zinc-aluminum coating solution, which is convenient for cleaning and replacement, includes a feeding tank assembly and a rotating assembly. A cover assembly is arranged at the top of the feeding tank assembly, and lifting assemblies are connected to both the left and right sides of the cover assembly. Moreover, a device frame is connected to the side of the lifting assembly. The rotating assembly is vertically installed in the middle of the lower end of the device frame. The rotating assembly includes a fixed table, a servo motor, and a support frame. The servo motor is horizontally installed at the upper end of the fixed table, and support frames are connected to the bottoms of both the left and right sides of the fixed table.

[0008] Furthermore, the feeding tank assembly includes a main tank body, a motor quick connector, a connecting block, and a feeding valve. Motor quick connectors are installed on both the left and right sides of the main tank body, connecting blocks are installed at the upper ends of both the front and back sides of the main tank body, and a feeding valve is arranged below the connecting block.

[0009] Furthermore, the cover assembly includes an upper cover, a feeding valve, a pressure relief valve, and a slider. A feeding valve is installed at the center of the top of the upper cover, a pressure relief valve is arranged on one side of the feeding valve, and sliders are installed on both the left and right sides of the upper cover.

[0010] Furthermore, the cover assembly further includes a micro motor and a fastening screw. Micro motors are installed on both the front and back sides of the upper cover, and a fastening screw is installed at the power output end of the bottom of the micro motor through a coupling.

[0011] Furthermore, the surface structure of the bottom opening of the upper cover matches the surface structure of the top opening of the main tank body, and the power output end of the servo motor is movably connected to the motor quick connector.

[0012] Furthermore, the fastening screw is in threaded connection with the connecting block, and the connection ports of the feeding valve and the injection valve both adopt a quick connector structure.

[0013] Furthermore, the lifting assembly includes an assembly frame, a stepping motor, and a lead screw. The stepping motor is vertically installed in the middle of the assembly frame, and the power output end of the bottom of the stepping motor is connected to the lead screw through a coupling.

[0014] Furthermore, the lead screw vertically penetrates through the slider and is in threaded connection with each other, and the sliders are symmetrically installed at the front and rear ends of the upper cover and are integrally structured with each other.

[0015] The present utility model provides a feeding device for preparing zinc-aluminum coating solution, which is convenient for cleaning and replacement, and has the following beneficial effects:

[0016] 1. In this utility model, motor quick connectors are symmetrically installed on the left and right sides of the main tank body, enabling the entire feeding tank assembly to be quickly docked with or structurally disassembled from the servo motor installed on the fixed platform. With the above structure, the feeding tank assembly and the rotating assembly can be flexibly docked or separated, facilitating maintenance or replacement. When the servo motor is started, it drives the main tank body connected to its power output end through the motor quick connector, and the main tank body can swing and adjust within a certain range with the motor quick connector as the center, thereby flipping and adjusting the originally vertically upward opening. Through the operation of the above structure, it can assist the operator to arbitrarily adjust the opening orientation of the main tank body to the greatest extent, so as to effectively clean and maintain the internal structure, avoiding the relatively cumbersome and inconvenient operation method for the operator to clean the inside of the main tank body with the aid of external equipment, and improving the operation efficiency and flexibility.

[0017] 2. In this utility model, feeding valves are symmetrically arranged on the front and back sides of the main tank body respectively. At the same time, a feeding valve is installed on the top of the upper cover, and both the feeding valve and the feeding valve adopt a quick connector structure. After the feeding tank assembly and the capping assembly are closed in structure, the feeding valve can be used to quickly dock with an external matching pipeline through the quick connector structure to inject materials into the main tank body at any time. And with the feeding valve, the quick connector structure can be used to cooperate with the connecting pipeline to connect with the downstream processing equipment, so as to effectively transport materials to the downstream equipment. By using the above structure, the feeding tank assembly and the downstream processing equipment can be connected or disconnected at any time according to needs, facilitating the maintenance of the feeding tank assembly, and further improving the overall flexibility of the device structure.

[0018] 3. In this utility model, sliders are installed on the left and right sides of the upper cover, and the lead screw vertically penetrates through the inside of the sliders. Therefore, when the stepping motor operates, it drives the connected lead screw to rotate axially vertically, enabling the capping assembly to move up and down along the surface of the lead screw. By using the above mechanism, the feeding tank assembly and the capping assembly can be flexibly and conveniently docked or separated, reducing the time-consuming and laborious problems of manual operation. Driven by the lifting assembly, after the capping assembly is docked with the feeding tank assembly, at this time, through the operation of the micro motors on the front and back sides of the upper cover, the connected fastening screws are driven to rotate axially vertically, and then screwed into the connecting blocks arranged on the front and back sides of the main tank body to ensure the connection firmness and tightness of the structure after the feeding tank assembly and the capping assembly are docked.

[0024] The following further describes in detail the implementation manners of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0025] As Figures 1 to 4 shown, a feeding device for preparing zinc-aluminum coating solution that is convenient for cleaning and replacement includes a feeding tank assembly 1 and a rotating assembly 5. A cover assembly 2 is provided at the top of the feeding tank assembly 1, and lifting assemblies 3 are connected to both the left and right sides of the cover assembly 2. Moreover, a device frame 4 is connected to the side of the lifting assembly 3. The rotating assembly 5 is vertically installed in the middle at the lower end of the device frame 4. The rotating assembly 5 includes a fixed table 501, a servo motor 502, and a support frame 503. A servo motor 502 is horizontally installed at the upper end of the fixed table 501, and support frames 503 are connected to both the left and right sides of the bottom of the fixed table 501. The feeding tank assembly 1 includes a main tank body 101, a motor quick connector 102, a connecting block 103, and a feeding valve 104. Motor quick connectors 102 are installed on both the left and right sides of the main tank body 101. Moreover, connecting blocks 103 are installed at the upper ends of both the front and rear sides of the main tank body 101, and a feeding valve 104 is provided below the connecting block 103. By symmetrically installing motor quick connectors 102 on both the left and right sides of the main tank body 101, the entire feeding tank assembly 1 can be quickly docked or structurally disassembled with the servo motor 502 installed on the fixed table 501. When the servo motor 502 is started, it will drive the main tank body 101 connected to its power output end through the motor quick connector 102, and can swing and adjust within a certain range with the motor quick connector 102 as the center, so as to flip and adjust the originally vertically upward opening.

[0026] As Figures 1 to 4 shown, the capping assembly 2 includes an upper cover 201, a filling valve 202, a pressure relief valve 203 and a slider 204. A filling valve 202 is installed at the center of the top of the upper cover 201, and a pressure relief valve 203 is arranged on one side of the filling valve 202. Sliders 204 are installed on both the left and right sides of the upper cover 201. The capping assembly 2 further includes a micro motor 205 and a fastening screw 206. Micro motors 205 are installed on both the front and back sides of the upper cover 201, and a fastening screw 206 is installed at the bottom power output end of the micro motor 205 through a coupling. The surface structure of the bottom opening of the upper cover 201 matches the surface structure of the top opening of the main tank 101. The power output end of the servo motor 502 is movably connected to the motor quick connector 102. Among them, both the filling valve 202 and the material conveying valve 104 adopt quick connector structures, so that after the feeding tank assembly 1 and the capping assembly 2 are closed in structure, the material conveying valve 104 can be used to quickly dock the structures through an externally matching pipeline, and materials can be injected into the main tank 101 at any time. By using the material conveying valve 104, the quick connector structure can be used to cooperate with the connecting pipeline to connect with downstream processing equipment, so as to effectively convey materials to downstream equipment.

[0027] As Figures 1 to 4 shown, the fastening screw 206 is threadedly connected to the connecting block 103. The connecting ports of the material conveying valve 104 and the filling valve 202 both adopt quick connector structures. The lifting assembly 3 includes an assembly frame 301, a stepping motor 302 and a lead screw 303. A stepping motor 302 is vertically installed in the middle of the assembly frame 301, and a lead screw 303 is connected to the bottom power output end of the stepping motor 302 through a coupling. The lead screw 303 vertically penetrates through the slider 204 and is threadedly connected to each other. The sliders 204 are symmetrically installed at the front and rear ends of the upper cover 201 and are integrally structured with each other. When the stepping motor 302 operates, it will drive the connected lead screw 303 to rotate axially vertically, so that the capping assembly 2 can move up and down along the surface of the lead screw 303. Driven by the lifting assembly 3, after the capping assembly 2 is docked with the feeding tank assembly 1, at this time, through the operation of the micro motors 205 on both the front and back sides of the upper cover 201, the connected fastening screws 206 are driven to rotate axially vertically, so as to screw into the connecting blocks 103 arranged on both the front and back sides of the main tank 101.

[0028] In summary, as Figures 1 to 4 shown, for the feeding device for preparing zinc-aluminum coating solution that is convenient for cleaning and replacement, when in use, first, when it is necessary to add materials into the feeding tank assembly 1, only the filling valve 202 installed at the center of the top of the upper cover 201 needs to be quickly connected to the feeding equipment through a pipeline, and then materials can be injected. During this process, the pressure relief valve 203 on one side of the filling valve 202 can be used to balance the air pressure inside the feeding tank assembly 1;

[0029] After the material is transported well, disconnect the connection with the feeding equipment, and then use the feeding valves 104 on the front and rear sides of the main tank body 101 to connect the entire feeding tank assembly 1 to the downstream processing equipment through a pipeline, so that the material inside the feeding tank assembly 1 can be continuously transported to the downstream processing equipment;

[0030] When it is necessary to clean the inside of the feeding tank assembly 1 or disassemble and replace it for maintenance, first start the micro motors 205 installed on the front and rear sides of the upper cover 201. Driven by the micro motors 205, the fastening screw rods 206 connected to the power output ends at the bottom thereof rotate axially in the vertical direction and are screwed out from the inside of the connecting blocks 103 on the front and rear sides of the main tank body 101. At the same time, the lifting assembly 3 will start to operate in cooperation with the operation of the micro motors 205. With the operation of the stepping motor 302 on the mounting rack 301, the lead screw 303 connected to the bottom thereof will be driven to rotate axially in the vertical direction, so that the entire cover assembly 2 connected to the lead screw 303 by the slider 204 will be lifted vertically. The lifting speed matches the screwing-out speed of the fastening screw rods 206, so that the feeding tank assembly 1 is separated from the cover assembly 2;

[0031] Subsequently, if it is necessary to clean the inside of the feeding tank assembly 1, only need to start the rotating assembly 5 in the device rack 4. Drive the main tank body 101 connected to it through the motor quick connector 102 by the servo motor 502 installed at the upper end of the fixed table 501, and then the main tank body 101 can be swung and adjusted at a certain vertical angle, so that the opening of the main tank body 101 faces the direction convenient for the operator to operate. When it is necessary to disassemble the feeding tank assembly 1, only need to use the characteristics of the motor quick connector 102 structure to separate the feeding tank assembly 1 from the rotating assembly 5, so as to facilitate the operator to replace or maintain it.

Many modifications and variations are obvious to those of ordinary skill in the art.
