Description

Technical Field

[0001] The utility model relates to the technical field of adding materials before stripping liquid mixing, in particular to a material adding cover plate structure of a stripping liquid mixing device. Background Art

[0002] When producing stripping liquid, multiple raw materials need to be mixed, and these raw materials are mainly liquid raw materials, and usually multiple liquid raw materials need to be added. According to different product requirements, the addition ratio of each raw material also needs to be adjusted. For example, NMP stripping liquid, the main ingredient N-methylpyrrolidone (NMP) accounts for a large proportion, usually in the range of 55%~56%, and there are other liquid ingredients such as ethanolamine, dimethyl sulfoxide (DMSO), ethylene glycol, etc.

[0003] The reaction kettle, preparation cylinder, mixing tank, etc. used when mixing the stripping liquid can be collectively referred to as a stripping liquid mixing device. These mixing devices are provided with a cover plate, on which there are devices such as a stirring motor, and a feeding port. Since the amount of material to be added each time may be different, the prior art usually requires on-site measurement of each raw material before adding the material. After a batch of materials is mixed and discharged, these tasks need to be repeated again, which is more troublesome. Utility Model Content

[0004] In view of the above-mentioned defects, the utility model provides a feeding cover plate structure for a stripping liquid mixing device, on which material tubes with designated raw materials evenly distributed in predetermined amounts can be placed, and material can be added conveniently. The same configuration can be used for repeated operations during multiple mixing operations, thereby improving production efficiency.

[0005] In order to achieve the purpose of this utility model, the following technologies are proposed:

[0006] A stripping liquid mixing device feeding cover plate structure, comprising:

[0007] The cover plate mechanism comprises a cover plate, a plurality of downwardly penetrating feeding ports are arranged in a circumferential array on the cover plate, and a plurality of ring ports are also formed on the upper surface of the cover plate, which are respectively concentric with the feeding ports;

[0008] A plurality of feeding mechanisms are assembled in a circular array on the upper end of the cover plate, the feeding mechanisms include a material pipe, a ring pipe matching the ring mouth is extended from the lower end of the material pipe, a plurality of side ports with the same width as the inner diameter of the material pipe and connected to the inner cavity of the material pipe are vertically arranged at one end of the outer peripheral side of the material pipe, and a layered plate is also matched in the side port.

[0009] Furthermore, the inner diameter of the material pipe is less than or equal to the inner diameter of the feeding port.

[0010] Furthermore, a first sealing strip is fixed to the inner wall of the side opening, and the layered plate is inserted into the first sealing strip.

[0011] Furthermore, a grip block is provided at one end of the layered plate.

[0012] Furthermore, both ends of the grip block are provided with arc surfaces facing inwards.

[0013] Furthermore, a second sealing strip is provided at the other end of the layered plate.

[0014] Furthermore, a tube cover is mounted on the upper end of the material tube.

[0015] The beneficial effects of this technical solution are:

[0016] The matching feeding mechanism can be pre-processed according to the proportion of each raw material of the specified product. The raw materials can be added to the material pipe before mixing and a layering plate can be inserted. The amount of the raw material in each grid is equal to the amount of the raw material to be mixed at one time. Then the material pipe can be stably fixed on the cover plate through the ring tube. Each time the material is added, a layering plate is pulled out of each feeding mechanism to make the raw material fall. After each mixing and discharging is completed, the above operation can be repeated, and the production efficiency is high. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0023] like Figure 1~Figure 5 The feeding cover structure of a stripping liquid mixing device shown comprises a cover mechanism 1 and a feeding mechanism 2.

[0024] The cover plate mechanism 1 comprises a cover plate 11 , on which a plurality of feeding ports 12 penetrating downward are arranged in a circumferential array, and a plurality of annular openings 13 respectively coaxial with the feeding ports 12 are also formed on the upper end surface of the cover plate 11 .

[0025] There are multiple feeding mechanisms 2, which are assembled on the upper end of the cover plate 11 in a circular array. The feeding mechanism 2 includes a material pipe 21, the inner diameter of the material pipe 21 is less than or equal to the inner diameter of the feeding port 12, and a ring pipe 22 matching the ring port 13 is extended from the lower end of the material pipe 21. A plurality of side ports 23 with the same width as the inner diameter of the material pipe 21 and connected to the inner cavity of the material pipe 21 are vertically arrayed at one end of the outer peripheral side of the material pipe 21. A first sealing strip 24 is fixed to the inner wall of the side port 23. Specifically, the first sealing strip 24 covers the inner bottom wall, the inner top wall and the two inner end walls of the side port 23. The side port 23 is also equipped with a layered Plate 25, specifically, the layered plate 25 is inserted into the first sealing strip 24, a grip block 26 is provided at one end of the layered plate 25, and arc surfaces 27 are respectively opened inward at both ends of the grip block 26, so that people can operate the grip block 26 by hand, and a second sealing strip 28 is provided at the other end of the layered plate 25. Specifically, the second sealing strip 28 covers the arc portion of the end of the layered plate 25, and a straight portion extending for a certain length. A pipe cover 29 is assembled at the upper end of the material tube 21, and a thread is also opened on the outer peripheral side of the upper end of the material tube 21, and a matching thread is opened on the inner peripheral side of the opening under the pipe cover 29, so that the pipe cover 29 can be tightened.

[0026] like Figure 1 As shown, different material tubes 21 have different lengths, and the spacing between the layer plates 25 is also different. This setting is because the amount of each raw material added is different. The length of the material tube 21 is proportional to the spacing between the layer plates 25. The smaller the value, the less the corresponding amount of raw material added, and the larger the value, the greater the corresponding amount of raw material added. In this way, each time when adding materials, the operation of each feeding mechanism 2 is to take out a layer plate 25, which is easy to operate.

[0027] The first sealing strip 24 can play two roles: prevent the liquid from leaking from the side of the material tube 21; provide a stronger friction force to the layered plate 25 so that when the layered plate 25 seals the inner cavity of the material tube 21, no additional parts are needed to fix it.

[0028] In this embodiment, the first sealing strip 24 and the second sealing strip 28 can be made of common waterproof sealing materials, such as solid polyurethane, polyamide, silicone, etc.

[0029] The above are only some of the embodiments listed in this application and are not intended to limit this application.
