Description

Technical Field

[0001] The present application relates to the field of thick-build anti-corrosion paint preparation technology, and in particular to a sampling device, water-based epoxy thick-build anti-corrosion paint preparation equipment and an anti-corrosion paint preparation method. Background Art

[0002] Waterborne epoxy high-build anti-corrosion paint is a coating based on a waterborne epoxy resin system, manufactured through a specific process using pigments, fillers, and additives. The mixing tank is a key piece of equipment in the preparation of waterborne epoxy high-build anti-corrosion paint. Various raw materials must be mixed and agitated in the mixing tank. However, current mixing tanks make it difficult for workers to ensure uniform mixing, leading to numerous problems in the anti-corrosion paint preparation process. Summary of the Invention

[0003] In order to improve the problem that it is difficult for staff to control the uniformity of material mixing in existing anti-corrosion paint preparation equipment, the present application provides a sampling device, which is arranged on a mixing tank, and a sampling port is arranged on the mixing tank corresponding to the sampling device. The sampling device includes a sampling tube that is slidably connected to the sampling port, one end of the sampling tube is a paint inlet, and the other end is a paint outlet, and also includes an elastic member 1 fixedly connected between the sampling tube and the mixing tank, and under the action of the elastic member 1, the paint inlet is located inside the sampling port.

[0004] By adopting the above scheme, when it is necessary to conduct a random inspection of the material in the mixing tank, by pressing the random inspection tube into the mixing tank, the random inspection port on the random inspection tube can be entered into the mixing tank. At this time, the material in the mixing tank can be discharged through the paint inlet, the random inspection tube and the paint outlet, thereby realizing the random inspection of the material in the mixing tank. After the pressure on the random inspection tube is released, the random inspection tube is reset under the action of the elastic member 1, the paint inlet enters the random inspection port, and the random inspection port is closed. Furthermore, a track is provided on the mixing tank corresponding to the random inspection port, and the sampling device also includes a pusher slidably connected to the track. A guide slope is provided on the random inspection tube for use with the pusher. During the movement of the pusher toward the random inspection tube, the pusher causes the paint inlet to enter the mixing tank through the guide slope.

[0005] By adopting the above solution, by pressing the pushing member so that the pushing member abuts against the guide inclined surface and moves along the guide inclined surface, the sampling inspection tube can be made to enter the mixing tank, which facilitates the sampling inspection work of the staff.

[0006] Furthermore, a second elastic member is provided between the pushing member and the mixing tank, and under the action of the second elastic member, the pushing member is separated from the sampling tube.

[0007] By adopting the above solution, the pushing member is made more stable when not in use.

[0008] Furthermore, the sampling device also includes a flushing component, which includes a flushing head. The flushing head is externally connected to a high-pressure water source, and a water inlet for use with the flushing head is correspondingly provided on the top of the sampling tube.

[0009] By adopting the above solution, the flushing head can flush the sampling inspection tube to ensure the cleanliness of the sampling inspection tube for the next use, while also preventing the sampling inspection tube from being blocked.

[0010] Furthermore, the flushing assembly also includes a collecting head adapted to the paint outlet, and the collecting head is externally connected to a wastewater collection pipe.

[0011] By adopting the above solution, the collection head can collect the wastewater generated by cleaning, ensuring the cleanliness of the environment around the preparation equipment.

[0012] Furthermore, the pushing member is located directly above the sampling tube and includes a main body and a connecting portion. The main body is provided with a connecting hole. One end of the connecting portion is slidably connected to the rail, and the other end of the connecting portion passes through the connecting hole and is slidably connected to the main body. The collecting head is coaxially arranged on one side of the paint outlet of the sampling inspection tube, and the collecting head is fixed to the main body; A slide is vertically provided on the main body, the flushing head is slidably connected to the slide, and when the sampling tube is inserted into the water inlet, the collecting head is inserted into the paint outlet.

[0013] By adopting the above solution, the entire operation process is completed by holding the flushing head with one hand and sliding the main body along the connecting part to insert the collection head into the paint outlet, and then sliding the flushing head downward to make the flushing head enter the water inlet. The operation is simple and convenient.

[0014] Furthermore, the flushing assembly also includes a positioning member, a groove is provided on the flushing head, a sliding channel is fixedly connected to the main body, the positioning member is slidably connected to the sliding channel, and an elastic member five is fixedly connected between the positioning member and the sliding channel. Under the action of the elastic member five, the positioning member presses the flushing head, and when the flushing head is extended into the water inlet, the positioning member extends into the groove.

[0015] By adopting the above solution, when the flushing head is inserted into the water inlet, the positioning member can limit the flushing head and the collecting head, making the entire flushing process more stable.

[0016] Furthermore, an elastic member three is fixedly connected between the main body and the connecting portion. Under the action of the elastic member three, the collecting head is separated from the paint outlet, and the main body is aligned with the guide inclined surface.

[0017] By adopting the above solution, after the sampling inspection tube is flushed, the pushing member is reset under the action of the elastic member three to facilitate the next material collection work.

[0018] Furthermore, an elastic member 4 is fixedly connected between the main body and the flushing head.

[0019] By adopting the above solution, the flushing head is more stable when not in use. At the same time, after flushing the sampling tube, the flushing head is reset under the action of the elastic member 4 to facilitate the next material collection work.

[0020] Furthermore, a transition slope is vertically provided on the flushing head, and the transition slope is located directly below the groove and is connected to the groove.

[0021] By adopting the above solution, after the sampling inspection tube is flushed, the staff pulls the positioning piece to gradually separate the positioning piece from the groove. During this process, when the positioning piece is separated from the groove, it will abut against the transition slope, ensuring that the flushing head rises slowly, and preventing the flushing head from being suddenly bounced up under the action of the elastic piece four, causing water droplets to splash.

[0022] In summary, the present invention has at least the following beneficial effects: 1. By providing a plurality of sampling devices on the side wall of the mixing tank, when it is necessary to perform random inspections on the material in the mixing tank, the sampling tube can be pressed into the mixing tank, causing the sampling port on the sampling tube to enter the mixing tank. At this time, the material in the mixing tank can be discharged through the paint inlet, the sampling tube, and the paint outlet, thereby achieving random inspection of the material in the mixing tank. After the pressure on the sampling tube is released, the sampling tube returns to its original position under the action of the elastic member 1, the paint inlet enters the sampling port, and the sampling port is sealed.

[0023] By combining the flushing assembly with the pushing member, on the one hand, the mutual coordination of various components is achieved, some unnecessary workpieces are optimized, and thus the production cost is reduced; on the other hand, in the process of flushing the sampling tube, the flushing head is held with one hand and the main body is slid along the connecting part to insert the collecting head into the paint outlet, and then the flushing head is slid downward to enter the water inlet, and the positioning member is extended into the groove on the flushing head, and the control switch is turned on to realize the cleaning of the sampling tube, thereby realizing the one-handed operation of the sampling tube flushing process, which greatly facilitates the cleaning of the exhaust pipe.

[0024] By setting a transition slope on the flushing head, after flushing the sampling inspection tube, the staff pulls the positioning piece to gradually disengage the positioning piece from the groove. In this process, when the positioning piece is out of the groove, it will abut against the transition slope, ensuring that the flushing head rises slowly, and avoiding the flushing head being suddenly bounced up under the action of the elastic piece 4, causing water droplets to splash.

DETAILED DESCRIPTION

[0027] A sampling device provided in the application embodiment, referring to Figure 1 The sampling device 2 is provided on the mixing tank 1. The top of the mixing tank 1 is provided with a feed port 11. A cover 111 is provided at the feed port 11 for closing the feed port 11. The bottom of the mixing tank 1 is provided with a discharge port 12. A stirring device for stirring the material is provided in the mixing tank 1. The above is the prior art and will not be described in detail in this case.

[0028] There are several groups of sampling devices 2, which are evenly arranged from top to bottom along the side wall of the mixing tank 1. During the process of mixing the materials in the mixing tank 1, the sampling devices 2 can perform random inspections on the materials at different positions in the mixing tank 1, so as to facilitate the control of the mixing uniformity of the materials.

[0029] Reference Figure 2Furthermore, a sampling port 13 communicating with the mixing tank 1 is provided on the side wall of the sampling device 2, and the sampling device 2 includes a sampling tube 3 slidably connected to the sampling port 13. Reference Figure 3 A paint inlet 31 is provided at one end of the sampling inspection tube 3 , and a paint outlet 32 ​​is provided at the other end of the sampling inspection tube 3 .

[0030] Reference Figure 2 An elastic member 33 is provided between the sampling inspection tube 3 and the side wall of the mixing tank 1. The elastic member 33 is generally a spring. Under the action of the elastic member 33, the paint inlet 31 is located in the sampling inspection port 13, and at the same time, the end of the sampling inspection tube 3 where the paint outlet 32 ​​is located extends out of the sampling inspection port 13.

[0031] When it is necessary to perform a random inspection on the material in the mixing tank 1, the random inspection tube 3 is pressed into the mixing tank 1, so that the random inspection port 13 on the random inspection tube 3 can enter the mixing tank 1. At this time, the material in the mixing tank 1 can be discharged through the paint inlet 31, the random inspection tube 3, and the paint outlet 32, thereby completing the random inspection of the material in the mixing tank 1. After the pressure on the random inspection tube 3 is released, the random inspection tube 3 returns to its original position under the action of the elastic member 1 33, and the paint inlet 31 enters the random inspection port 13, and the random inspection port 13 is sealed.

[0032] In order to make it easier for the material in the sampling inspection to be discharged through the sampling inspection tube 3, the paint inlet 31 is located on the side wall of the sampling inspection tube 3. At the same time, the sampling inspection port 13 is a rectangular port, and the corresponding cross-section of the sampling inspection tube 3 is a rectangular port adapted to the sampling inspection port 13 to prevent the sampling inspection tube 3 from rotating in the sampling inspection port 13 and affecting the discharge of the material, making the sampling inspection tube 3 more stable.

[0033] The sampling device 2 also includes a pusher 4 for use with the sampling tube 3. The pusher 4 is located directly above the sampling tube 3. A track 14 is vertically provided on the side wall of the corresponding mixing tank 1. The track 14 is a groove body with a dovetail cross-section opened on the side wall of the mixing tank 1. The pusher 4 is slidably connected to the track 14. A guide slope 34 for use with the pusher 4 is provided on the top of the sampling tube 3. By pressing the pusher 4 so that the pusher 4 abuts against the guide slope 34 and moves along the guide slope 34, the sampling tube 3 can be entered into the mixing tank 1, facilitating the staff's sampling inspection work.

[0034] In addition, an elastic member 43 is provided between the pushing member 4 and the mixing tank 1 . The elastic member 43 is generally a spring. Under the action of the elastic member 43 , the pushing member 4 is separated from the guide slope 34 and stably maintained above the sampling tube 3 .

[0035] The sampling device 2 also includes a flushing component 5. After each sampling of the material by the sampling tube 3 is completed, the flushing component 5 can be used to flush the sampling tube 3 to ensure the cleanliness of the sampling tube 3 for the next use, while also preventing the sampling tube 3 from being blocked.

[0036] Specifically, the flushing assembly 5 includes a flushing head 51 disposed on one side of the sampling tube 3. The flushing head 51 is connected to an external high-pressure water source and is also provided with a control switch. The top of the corresponding sampling tube 3 is provided with a water inlet 35 for use with the flushing head 51. The flushing assembly 5 also includes a collection head 52 for use with the paint outlet 32 ​​and is externally connected to a wastewater collection pipe.

[0037] After the sampling tube 3 is used, the collecting head 52 is inserted into the paint inlet 31, the flushing head 51 is inserted into the water inlet 35 on the sampling tube 3, and the control switch is turned on. The flushing water enters the sampling tube 3 to flush the sampling tube 3, and is discharged through the collecting head 52 after flushing.

[0038] In order to achieve the cleaning of the sampling tube 3 more conveniently.

[0039] The pushing member 4 includes a connecting portion 41 and a main body 42. The connecting portion 41 is arranged parallel to and directly above the sampling tube 3. One end of the connecting portion 41 is slidably connected to the track 14. The elastic member 33 is fixed between the mixing tank 1 and the connecting portion 41. The other end of the connecting portion 41 is connected to the main body 42. The main body 42 is vertically arranged. The main body 42 is used to realize the function of the pushing member 4, and a connecting hole 421 adapted to the connecting hole 421 is opened on the main body 42. The connecting portion 41 passes through the connecting hole 421 and is slidably connected to the main body 42.

[0040] The collecting head 52 is coaxially arranged at the paint outlet 32 ​​of the sampling tube 3, and there is a gap between the collecting head 52 and the collecting outlet. The collecting tube is fixed to the main body 42. The collecting head 52 can be inserted into the paint outlet 32 ​​by sliding the main body 42 along the connecting portion 41.

[0041] A slide 422 is vertically provided on the main body 42. The slide 422 is a dovetail-shaped groove body opened on the main body 42. The flushing head 51 is vertically slidably connected to the slide 422. The corresponding water inlet 35 is opened to the top of the sampling tube 3. When the collection head 52 is inserted into the paint outlet 32, the flushing head 51 is aligned with the water inlet 35. At this time, pressing the flushing head 51 makes the flushing head 51 enter the water inlet 35. Turning on the control switch can realize flushing of the sampling tube 3. The entire operation process is completed by holding the flushing head 51 with one hand, sliding the main body 42 along the connecting part 41, inserting the collecting head 52 into the paint outlet 32, and then sliding the flushing head 51 downward to make the flushing head 51 enter the water inlet 35. The operation is simple and convenient.

[0042] A third elastic member 412, typically a spring, is disposed between the main body 42 and the connecting portion 41. This member 412 aligns the main body 42 with the guide ramp 34, facilitating spot checks. Furthermore, a fourth elastic member 511, typically a spring, is disposed between the flushing head 51 and the main body 42. This member 511 stabilizes the flushing head 51 on the main body 42, minimizing any impact on spot checks.

[0043] In order to make the flushing component 5 more stable during operation, the flushing component 5 also includes a positioning member 6. When the flushing head 51 is inserted into the water inlet 35, the positioning member 6 can limit the flushing head 51 and the collecting head 52, making the entire flushing process more stable.

[0044] In addition, when the paint inlet 31 enters the sampling inspection port 13, the water inlet 35 also enters the sampling inspection port 13, so that the paint can be prevented from being discharged through the water inlet 35 during the process of sampling the paint.

[0045] Reference Figure 2 and Figure 4 Specifically, a sliding channel 7 is fixedly connected horizontally to the main body 42, and the positioning member 6 is slidably connected to the sliding channel 7. An elastic member 5 71 is fixedly connected between the positioning member 6 and the sliding channel 7. The elastic member 5 71 is generally a spring. Under the action of the elastic member 5 71, the positioning member 6 extends out of the sliding channel 7 and presses the flushing head 51. At the same time, a groove 512 is provided on the flushing head 51 for use with the positioning member 6. When the flushing head 51 is extended into the water inlet 35, the positioning member 6 is extended into the groove 512 under the action of the elastic member 5 71. At this time, the positioning member 6 can limit the flushing head 51 from separating upward from the water inlet 35. Since the water inlet 35 can limit the horizontal movement of the flushing head 51, the collecting head 52 is fixed.

[0046] Reference Figure 5 Furthermore, a transition slope 513 is provided on the flushing head 51. The transition slope 513 is located directly below the groove 512 and is in communication with the groove 512. After flushing the sampling tube 3, the staff member pulls the positioning member 6 to gradually disengage the positioning member 6 from the groove 512. During this process, when the positioning member 6 disengages from the groove 512, it abuts against the transition slope 513, ensuring that the flushing head 51 rises slowly and preventing the flushing head 51 from being suddenly bounced up by the elastic member 511, causing water droplets to splash.

[0047] The implementation principle of this case is as follows: the material is placed in the mixing tank 1, and the stirring device is started to stir the material in the mixing tank 1. During the stirring process of the material in the mixing tank 1, the staff can use different sampling devices 2 to perform random sampling of the material at different positions in the mixing tank to observe the mixing status of the material. Specifically, a transparent container is placed at the paint outlet 32. The staff presses the pusher 4 to allow the paint inlet 31 of the sampling tube 3 to enter the mixing tank 1. The material enters the container through the sampling tube 3. The restriction on the pusher 4 is then released. The pusher 4 is reset under the action of the elastic member 2, and the sampling tube 3 is reset under the action of the elastic member 1 33. Then, by holding the flushing head 51 with one hand, the main body 42 is slid along the connecting portion 41 to insert the collecting head 52 into the paint outlet 32. Then, the flushing head 51 is slid downward to allow the flushing head 51 to enter the water inlet 35, and the positioning member 6 is extended into the groove 512 on the flushing head 51. The control switch is turned on to clean the sampling tube 3.

[0048] A waterborne epoxy high-build anticorrosive paint preparation device with a sampling device includes a mixing tank 1. The top of the mixing tank 1 is provided with a feed port 11, a cover 111 is provided at the feed port 11 for sealing the feed port 11, and a discharge port 12 is provided at the bottom of the mixing tank 1. A stirring device for stirring the material is provided in the mixing tank 1. Several groups of sampling devices 2 are provided on the side wall of the mixing tank 1. The groups of sampling devices 2 are evenly arranged along the side wall of the mixing tank 1 from top to bottom.

[0049] The ground pigment and filler slurry are mixed with water-based epoxy emulsion, defoamer, leveling agent and other additives and put into the mixing tank 1 for thorough stirring. During the mixing process, the staff can use different sampling devices 2 to check the materials at different positions in the mixing tank 1 to observe the mixing status of the materials and ensure that the components are evenly mixed. A method for preparing waterborne epoxy high-build anti-corrosion paint using waterborne epoxy high-build anti-corrosion paint preparation equipment comprises the following steps: S1.

During the grinding process, the fineness of the slurry needs to be tested regularly to ensure product quality; S4, Hybrid The ground pigment and filler slurry are mixed with other additives such as water-based epoxy emulsion, defoamer, leveling agent, etc. and put into the mixing tank 1 for thorough stirring. During the mixing process, the staff can use different sampling devices 2 to perform random inspections on the materials at different positions in the mixing tank 1 to observe the mixing status of the materials and continuously ensure that the components are evenly mixed. S5. Adjust viscosity According to actual needs, the viscosity of the paint can be adjusted by adding an appropriate amount of thickener or diluent to make it meet the requirements of spraying or brushing; S6, maturation Allow the mixed paint to sit for a while to allow the components to fully react and blend, improving the paint's stability and performance. The curing time is usually determined by the specific formula and process requirements; S7, Filter Filter the matured paint to remove impurities and bubbles to ensure that the paint is pure and free of impurities; S8. Packaging Put the filtered paint into the packaging barrel and seal it tightly. During the packaging process, care must be taken to prevent the paint from leaking and contamination.
