[0002] The water-based epoxy thick paste anticorrosive paint is a kind of coating based on water-based epoxy resin system, which is made by adding pigments, fillers and additives and through a specific process. In the preparation process of the water-based epoxy thick paste anticorrosive paint, the mixing and stirring tank is one of the key equipment, and various raw materials need to be put into the stirring tank for mixing and stirring. At present, it is difficult for the staff to control the uniformity of the material mixing during the mixing process of the mixing and stirring tank, which causes many problems in the preparation process of the anticorrosive paint. SUMMARY

[0003] In order to improve the problem that it is difficult for the staff to control the uniformity of the material mixing in the existing anticorrosive 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 comprises a sampling pipe which is slidably connected into the sampling port, one end of the sampling pipe is an inlet port, and the other end is an outlet port. An elastic member one is fixed between the sampling pipe and the mixing tank, and the inlet port is located in the sampling port under the action of the elastic member one.

[0004] By adopting the above scheme, when it is necessary to sample the material in the mixing tank, the sampling port on the sampling pipe can enter the mixing tank by pressing the sampling pipe into the mixing tank. At this time, the material in the mixing tank can be discharged through the inlet port, the sampling pipe and the outlet port, thereby realizing the sampling work of the material in the mixing tank. After the pressing on the sampling pipe is released, the sampling pipe is reset under the action of the elastic member one, the inlet port enters the sampling port, and the sampling port is closed. Further, a track is arranged on the mixing tank corresponding to the sampling port, and the sampling device further comprises a pushing member which is slidably connected into the track. A guide slope is arranged on the sampling pipe and used in cooperation with the pushing member. During the movement of the pushing member towards the sampling pipe, the pushing member makes the inlet port enter the mixing tank through the guide slope.

[0005] By adopting the above scheme, the sampling pipe can enter the mixing tank by pressing the pushing member to make the pushing member abut against and move along the guide slope, which facilitates the sampling work of the staff.

[0006] Further, an elastic member two is arranged between the pushing member and the mixing tank, and the pushing member is separated from the sampling pipe under the action of the elastic member two.

[0007] Through the above scheme, the pusher is more stable in the unused state.

[0008] Further, the sampling device further comprises a flushing assembly, the flushing assembly comprising a flushing head, the flushing head being circumscribed by a high-pressure water source, and the top of the sampling pipe being provided with a water inlet matched with the flushing head.

[0009] Through the above scheme, the flushing head can flush the sampling pipe, ensure the cleanliness of the sampling pipe, facilitate the next use, and also prevent the sampling pipe from being blocked.

[0010] Further, the flushing assembly further comprises a collection head matched with the paint outlet, and the collection head is circumscribed by a waste water collection pipe.

[0011] Through the above scheme, the collection head can collect the waste water generated by cleaning, and ensure the cleanliness of the environment around the preparation equipment.

[0012] Further, the pusher is located directly above the sampling pipe, and comprises a main body and a connecting portion, the main body being provided with a connecting hole, one end of the connecting portion being slidably connected to the track, and the other end of the connecting portion penetrating through the connecting hole and being slidably connected to the main body.

[0013] The collection head is coaxially arranged on one side of the paint outlet of the sampling pipe, and the collection head is fixedly connected to the main body.

[0014] The main body is vertically provided with a slide, and the flushing head is slidably connected to the slide, and when the sampling pipe is inserted into the water inlet, the collection head is inserted into the paint outlet.

[0015] Through the above scheme, the entire operation process is completed by holding the flushing head with one hand, sliding the main body along the connecting portion 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.

[0016] Further, the flushing assembly further comprises a positioning member, the flushing head being provided with a groove, the main body being fixedly connected with a sliding channel, the positioning member being slidably connected to the sliding channel, and an elastic member five being fixedly connected between the positioning member and the sliding channel, the positioning member being pressed against the flushing head under the action of the elastic member five, and the positioning member being inserted into the groove when the flushing head is inserted into the water inlet.

[0017] Through the above scheme, when the flushing head is inserted into the water inlet, the positioning member can limit the flushing head and the collection head, making the entire flushing process more stable.

[0018] Further, the main body part and the connecting part are fixed with elastic member three, and the collecting head is separated from the paint outlet under the action of the elastic member three, and the main body part is aligned with the guide slope.

[0019] By adopting the above scheme, the pusher is reset under the action of the elastic member three after the flushing of the sampling pipe, which facilitates the next material collection work.

[0020] Further, the main body part and the flushing head are fixed with elastic member four.

[0021] By adopting the above scheme, the flushing head is more stable in the non-use state, and the flushing head is reset under the action of the elastic member four after the flushing of the sampling pipe, which facilitates the next material collection work.

[0022] Further, a transition slope is vertically arranged on the flushing head, and the transition slope is located below the groove and communicates with the groove.

[0023] By adopting the above scheme, after the flushing of the sampling pipe, the worker pulls the positioning member to make the positioning member gradually separate from the groove, and in this process, when the positioning member separates from the groove, the positioning member abuts against the transition slope, so that the flushing head slowly rises, and water droplets are prevented from splashing due to the sudden bouncing of the flushing head under the action of the elastic member four.

[0024] In summary, the present application has at least the following advantages:

[0025] 1. By arranging a plurality of sampling devices on the sidewall of the mixing tank, when it is necessary to sample the material in the mixing tank, the sampling port on the sampling pipe can enter the mixing tank by pressing the sampling pipe into the mixing tank, and at this time, the material in the mixing tank can be discharged through the paint inlet, the sampling pipe and the paint outlet, thereby realizing the sampling of the material in the mixing tank. After the pressing of the sampling pipe is released, the sampling pipe is reset under the action of the elastic member one, and the paint inlet enters the sampling port, and the sampling port is closed.

[0026] 2. By combining the flushing assembly with the pusher, on the one hand, the mutual coordination of various components is realized, and some unnecessary workpieces are optimized, thereby reducing the manufacturing cost, and on the other hand, during the flushing of the sampling pipe, the main body part is slid along the connecting part by holding the flushing head with one hand to insert the collecting head into the paint outlet, and then the flushing head is slid downward to make the flushing head enter the water inlet, and the positioning member is inserted into the groove on the flushing head, and the control switch is opened to realize the cleaning of the sampling pipe, thereby realizing the one-handed operation of the sampling pipe flushing process, and greatly facilitating the cleaning of the sampling pipe.

[0027] 3、By setting the transition slope on the flushing head, after flushing the sampling pipe, the worker pulls the positioning member to make the positioning member gradually separate from the groove. In this process, when the positioning member separates from the groove, it will abut on the transition slope, ensuring that the flushing head slowly rises, avoiding the flushing head being suddenly bounced up under the action of the elastic member four, causing water droplets to splash.

DETAILED DESCRIPTION

[0035] The sampling device provided by the application embodiment, with reference to Figure 1 , the sampling device 2 is arranged on the mixing tank 1, the mixing tank 1 is provided with a feed inlet 11 at the top, the feed inlet 11 is provided with a cover 111 for closing the feed inlet 11, and the bottom of the mixing tank 1 is provided with a discharge outlet 12. The mixing tank 1 is provided with a stirring device for stirring the material. The above is the prior art which will not be described in detail in this case.

[0036] ​The sampling device 2 is provided on the side wall of the mixing tank 1 in several groups, and the sampling device 2 is uniformly arranged from top to bottom. During the mixing process of the mixing tank 1, the sampling device 2 can take samples of the materials at different positions in the mixing tank 1, so as to control the mixing uniformity of the materials.

[0037] Referring to Figure 2 Further, the side wall of the mixing tank 1 at the sampling device 2 is provided with a sampling opening 13 communicating with the mixing tank 1, and the sampling device 2 comprises a sampling pipe slidingly connected into the sampling opening 13,

[0038] Referring to Figure 3 One end of the sampling pipe is provided with a paint inlet 31, and the other end of the sampling pipe is provided with a paint outlet 32.

[0039] Referring to Figure 2 The sampling pipe and the side wall of the mixing tank 1 are provided with an elastic member 33, and the elastic member 33 is generally selected as a spring. Under the action of the elastic member 33, the paint inlet 31 is located in the sampling opening 13, and the end of the sampling pipe where the paint outlet 32 is located extends out of the sampling opening 13.

[0040] When it is necessary to take samples of the materials in the mixing tank 1, the sampling pipe can be pressed into the mixing tank 1, so that the sampling opening 13 on the sampling pipe enters the mixing tank 1. At this time, the materials in the mixing tank 1 can be discharged through the paint inlet 31, the sampling pipe and the paint outlet 32, thereby realizing the sampling of the materials in the mixing tank 1. After the pressing of the sampling pipe is released, the sampling pipe is reset under the action of the elastic member 33, the paint inlet 31 enters the sampling opening 13, and the sampling opening 13 is closed.

[0041] In order to make the materials in the sampling pipe more easily discharged, the paint inlet 31 is located on the side wall of the sampling pipe. At the same time, the sampling opening 13 is a rectangular opening, and the cross section of the corresponding sampling pipe is a rectangular shape matched with the sampling opening 13, so as to avoid the rotation of the sampling pipe in the sampling opening 13 affecting the discharge of the materials, and make the sampling pipe more stable.

[0042] The sampling device 2 further comprises a pushing member 4 used in cooperation with the sampling pipe, and the pushing member 4 is located directly above the sampling pipe. A vertical track 14 is provided on the side wall of the mixing tank 1, and the track 14 is a groove with a dovetail-shaped cross section opened on the side wall of the mixing tank 1. The pushing member 4 is slidingly connected into the track 14. The top of the sampling pipe is provided with a guide slope 34 used in cooperation with the pushing member 4. By pressing the pushing member 4 to make the pushing member 4 abut against and move along the guide slope 34, the sampling pipe can enter the mixing tank 1, which is convenient for the sampling work of the staff.

[0043] The elastic member two 43 is arranged between the pushing member 4 and the mixing tank 1, and is generally selected as a spring. Under the action of the elastic member two 43, the pushing member 4 is separated from the guide inclined surface 34 and stably kept above the sampling pipe.

[0044] The sampling device 2 further comprises a flushing assembly 5. After each sampling pipe finishes sampling the material, the flushing assembly 5 can be used to flush the sampling pipe, so as to ensure the cleanliness of the sampling pipe, facilitate the next use, and prevent the sampling pipe from being blocked.

[0045] Specifically, the flushing assembly 5 comprises a flushing head 51 arranged on one side of the sampling pipe. The flushing head 51 is connected with an external high-pressure water source, and a control switch is further arranged on the flushing head 51. Correspondingly, the top of the sampling pipe is provided with a water inlet 35 for cooperation with the flushing head 51. The flushing assembly 5 further comprises a collecting head 52 for cooperation with the paint outlet 32, and the collecting head 52 is connected with a waste water collecting pipe.

[0046] After the sampling pipe is used, the collecting head 52 is inserted into the position of the paint inlet 31, the flushing head 51 is inserted into the position of the water inlet 35 on the sampling pipe, and the control switch is turned on. The flushing water enters the sampling pipe to flush the sampling pipe, and is discharged through the collecting head 52 after flushing.

[0047] In order to more conveniently realize the cleaning of the sampling pipe.

[0048] The pushing member 4 comprises a connecting portion 41 and a main body portion 42. The connecting portion 41 is arranged in parallel above the sampling pipe, and one end of the connecting portion 41 is slidably connected into the track 14. The elastic member one 33 is fixedly connected between the mixing tank 1 and the connecting portion 41. The other end of the connecting portion 41 is connected with the main body portion 42. The main body portion 42 is vertically arranged, and is used to realize the function of the pushing member 4. Connection holes 421 are arranged in the main body portion 42, and the connecting portion 41 passes through the connection holes 421 and is slidably connected with the main body portion 42.

[0049] The collecting head 52 is coaxially arranged at the position of the paint outlet 32 of the sampling pipe, and a spacing exists between the collecting head 52 and the collecting opening. The collecting pipe is fixedly connected to the main body portion 42. The collecting head 52 can be inserted into the paint outlet 32 by sliding the main body portion 42 along the connecting portion 41.

[0050] The main body 42 is vertically provided with a sliding channel 422, which is a groove with dovetail-shaped cross section opened on the main body 42, the flushing head 51 is vertically and slidingly connected into the sliding channel 422, the water inlet 35 is opened on the top of the sampling pipe, and when the collecting head 52 is inserted into the paint outlet 32, the flushing head 51 is aligned with the water inlet 35. At this time, the flushing head 51 is pressed to enter the water inlet 35, and the control switch is opened to realize the flushing of the sampling pipe. In the whole operation process, the main body 42 is slid along the connecting part 41 by holding the flushing head 51 with one hand to insert the collecting head 52 into the paint outlet 32, and then the flushing head 51 is slid downward to enter the water inlet 35, so that the operation is completed, which is simple and convenient.

[0051] The main body 42 and the connecting part 41 are provided with an elastic member three 412, which is generally selected from a spring; under the action of the elastic member three 412, the main body 42 is aligned with the guide slope 34, which is convenient for people to sample. In addition, the elastic member four is arranged between the flushing head 51 and the main body 42, which is generally selected from a spring. Under the action of the elastic member four, the flushing head 51 can be stably installed on the main body 42, which reduces the influence on the sampling work.

[0052] In order to make the flushing assembly 5 more stable in the working process, the flushing assembly 5 further comprises 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, so that the whole flushing process is more stable.

[0053] In addition, when the paint inlet 31 enters the sampling port 13, the water inlet 35 also enters the sampling port 13, so that the paint can be prevented from being discharged through the water inlet 35 in the process of sampling paint.

[0054] Referring to Figure 2 and Figure 4 , specifically, the main body 42 is horizontally and fixedly connected with a sliding channel 7, the positioning member 6 is slidingly connected into the sliding channel 7, an elastic member five 71 is fixedly connected between the positioning member 6 and the sliding channel 7, which is generally selected from a spring. Under the action of the elastic member five 71, the positioning member 6 extends out of the sliding channel 7 and presses the flushing head 51. Meanwhile, a groove 512 is opened on the flushing head 51 for cooperation with the positioning member 6. When the flushing head 51 extends into the water inlet 35, the positioning member 6 extends into the groove 512 under the action of the elastic member five 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 fixing of the collecting head 52 is realized.

[0055] Referring to Figure 5Further, the flushing head 51 is provided with a transition slope 513 located directly below and communicated with the groove 512. After the flushing of the sampling pipe is completed, the worker pulls the positioning member 6 to gradually disengage the positioning member 6 from the groove 512. In this process, when the positioning member 6 disengages from the groove 512, it abuts against the transition slope 513, so that the flushing head 51 slowly rises, avoiding the flushing head 51 from being suddenly bounced up by the elastic member four, causing water droplets to splash.

[0056] The principle of the case is that the material is placed in the mixing tank 1, and the stirring device is started to stir the material in the mixing tank 1. In the process of stirring the material in the mixing tank 1, the worker can observe the mixing of the material by different sampling devices 2 to realize sampling of the material at different positions in the stirring tank. Specifically, the transparent container is placed at the paint outlet 32, the worker presses the pusher 4 to make the paint inlet 31 of the sampling pipe enter the mixing tank 1, the material enters the container through the sampling pipe, then the restriction on the pusher 4 is released, the pusher 4 is reset under the action of the elastic member two, and the sampling pipe is reset under the action of the elastic member one 33. Then the flushing head 51 is held with one hand to make the main body 42 slide along the connecting part 41 to insert the collecting head 52 into the paint outlet 32, then the flushing head 51 is slid downward to make the flushing head 51 enter the water inlet 35, and the positioning member 6 extends into the groove 512 on the flushing head 51, and the control switch is opened to clean the sampling pipe.
