Description

Technical Field

[0001] This utility model relates to the field of adhesive treatment technology, and more specifically, to a cantilevered twin-screw pump adhesive sedimentation, separation and purification device. Background Technology

[0002] In the production processes of chemicals, coatings, adhesives, and other products, adhesive solutions are common raw materials or intermediate products. However, due to factors such as production processes and storage conditions, various impurities, such as insoluble particles and precipitates, often become mixed into the adhesive solution. The presence of these precipitated impurities can seriously affect the quality and performance of the adhesive solution. For example, in coating production, impurities can lead to uneven coating surfaces and defects such as particles. In the use of adhesives, precipitated impurities may reduce bond strength and affect the product's performance.

[0003] Cantilever twin-screw pumps have advantages such as stable delivery, low pressure pulsation, and strong self-priming capability, and are widely used in the field of adhesive delivery. However, most existing adhesive processing devices based on cantilever twin-screw pumps only have delivery functions and lack effective sedimentation, separation, and purification functions, which cannot meet the quality requirements of adhesives in actual production. Therefore, we designed a cantilever twin-screw pump adhesive sedimentation, separation, and purification device. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a cantilevered twin-screw pump adhesive sedimentation separation and purification device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cantilevered twin-screw pump adhesive sedimentation separation and purification device, comprising a base plate, a shell disposed on one side above the base plate, and supports fixed between the two side walls of the shell and the base plate, a cover plate installed on the top of the shell, and a stirring mechanism disposed inside the shell, an inlet pipe connected to one side above the shell, an outlet pipe connected to the bottom of the shell, and a lower valve installed on the outlet pipe, a side shell disposed on one side of the shell, and side supports fixed between the two sides of the side shell and the base plate, a connecting pipe connected between the side shell and the base plate, and a valve installed on the connecting pipe, a side cover plate installed on the top of the side shell, and a filtering mechanism disposed inside the side shell, a side outlet pipe connected to the bottom of the side shell, a horizontal plate fixed between the two side supports, a cantilevered twin-screw pump fixedly installed on the top of the horizontal plate, and the inlet of the cantilevered twin-screw pump connected to the side outlet pipe.

Multiple stirring blades are fixed around the lower part of the rotating rod.

[0009] As a preferred embodiment of this utility model, both the side cover plate and the inner wall of the cover plate are fixed with sealing gaskets.

[0010] As a preferred embodiment of the present invention, the filtration mechanism includes an inner shell and an annular support plate. The annular support plate is fixed to the lower part of the side shell, and the inner shell is placed above the annular support plate. An upper filter screen is fixed to the upper part of the inner shell, and a lower filter screen is fixed to the lower part of the inner shell. The mesh diameter of the upper filter screen is larger than that of the lower filter screen.

[0012] As a preferred embodiment of this utility model, an exhaust pipe is connected to one side above the side cover plate, and an air valve is installed on the exhaust pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model connects to the adhesive delivery pipeline via a feed pipe, allowing the adhesive to enter the housing through the feed pipe. When the adhesive enters the housing, it can settle.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 3 As shown, this utility model provides a cantilevered twin-screw pump adhesive sedimentation separation and purification device, including a base plate 1, a housing 2 is provided on one side above the base plate 1, and support legs 4 are fixed between the two side walls of the housing 2 and the base plate 1. A cover plate 3 is installed on the top of the housing 2, and a stirring mechanism is provided inside the housing 2. A feed pipe 5 is connected to the top of the housing 2, which is connected to an adhesive conveying pipeline. The adhesive will enter the housing 2 through the feed pipe 5. A discharge pipe 6 is connected to the bottom of the housing 2, and a lower valve is installed on the discharge pipe 6. A storage tank 7 is placed on the bottom plate 1 directly below the discharge pipe 6. When the adhesive enters the housing 2, the adhesive can be precipitated. The stirring mechanism can prevent the adhesive from solidifying during the sedimentation separation process. By turning the lower valve to open the discharge pipe 6, the impurities precipitated at the bottom of the housing 2 can be discharged. The storage tank 7 can store the discharged impurities.

[0022] A side shell 8 is provided on one side of the shell 2, and side support legs 15 are fixed between both sides of the side shell 8 and the base plate 1. A connecting pipe 9 connects the side shell 8 and the shell 2, and a valve 10 is installed on the connecting pipe 9. A side cover plate 11 is installed on the top of the side shell 8, and a filter mechanism is provided inside the side shell 8. A side discharge pipe is connected to the bottom of the side shell 8. A horizontal plate is fixed between the two side support legs 15, and a cantilevered twin-screw pump 14 is fixedly installed on the top of the horizontal plate. The feed inlet of the cantilevered twin-screw pump 14 is connected to the side discharge pipe. The arm-type twin-screw pump 14 is driven by a variable frequency motor. The motor speed is adjusted by the frequency converter, thereby controlling the flow rate and pressure of the adhesive. When the adhesive in the housing 2 settles to a certain extent, the valve 10 is opened. The adhesive after preliminary sedimentation enters the side housing 8 through the connecting pipe 9. The adhesive is filtered and purified by the filtration mechanism in the side housing 8. The purified adhesive enters the cantilever twin-screw pump 14 through the side outlet. The cantilever twin-screw pump 14 can then transport the purified adhesive.

[0023] The bottoms of both the shell 2 and the side shell 8 are conical, which allows for better discharge of adhesive and precipitated impurities from the shell 2 and the side shell 8.

[0024] The stirring mechanism includes a motor 16, which is fixedly installed above the cover plate 3. A rotating rod 17 is connected below the motor 16. One end of the rotating rod 17 passes through the cover plate 3 and extends to the bottom of the housing 2. A sealed bearing is fixed at the contact point between the cover plate 3 and the rotating rod 17. Multiple stirring blades 18 are fixed around the bottom of the rotating rod 17. Starting the motor 16 can drive the rotating rod 17 to rotate. The rotation of the rotating rod 17 can drive the multiple stirring blades 18 to rotate, thereby stirring the sediment in the housing 2.

[0025] Both the side cover plate 11 and the cover plate 3 have sealing gaskets fixed to their inner walls. These gaskets can increase the sealing between the side cover plate 11 and the cover plate 3 and the side housing 8 and the housing 2.

[0026] The filtration mechanism includes an inner housing 19 and an annular support plate 23. The annular support plate 23 is fixed inside the lower part of the side housing, and the inner housing 19 is placed above the annular support plate 23. A handle 20 is fixed on the upper part of the inner housing 19. An upper filter screen 21 is fixed inside the upper part of the inner housing 19, and a lower filter screen 22 is fixed inside the lower part of the inner housing 19. The mesh diameter of the upper filter screen 21 is larger than that of the lower filter screen 22. The upper filter screen 21 is used to intercept larger particles of impurities, and the lower filter screen 22 is a high-precision filter screen that can filter out fine particles of impurities, thereby purifying the adhesive liquid.

[0027] The side cover plate 11 is connected to an exhaust pipe 12 on one side above it, and an air valve 13 is installed on the exhaust pipe 12. Opening the air valve 13 allows the gas generated by the adhesive during the purification process to be discharged through the exhaust pipe 12, thereby maintaining the pressure balance inside the cavity.

[0028] The working principle and usage process of this utility model are as follows: The glue is connected to the glue delivery pipeline through the feed pipe 5, and the glue will enter the housing 2 through the feed pipe 5. When the glue enters the housing 2, it can be precipitated. When the glue in the housing 2 has settled to a certain extent, the valve is opened, and the glue after preliminary precipitation enters the side housing 8 through the connecting pipe. The glue can be filtered and purified by the filtration mechanism in the side housing 8. The purified glue enters the cantilever twin-screw pump 14 through the side outlet. The cantilever twin-screw pump 14 can transport the purified glue. The cantilever twin-screw pump 14 is driven by a variable frequency motor. The motor speed is adjusted by the frequency converter to control the flow rate and pressure of the glue, so as to adapt to different production needs.
