Description

Technical Field

[0001] This utility model relates to the field of vacuum trap technology, specifically a vacuum trap for drying and preventing leakage of refined sterols. Background Technology

[0002] Sterol vacuum traps are mainly used to capture and remove gas or vapor molecules in a vacuum system to maintain a high vacuum environment. The structure of common vacuum traps on the market mainly includes a tank and a trap filter bag located inside the tank. The top of the tank has an outlet pipe and the bottom has an inlet pipe. The end of the outlet pipe located inside the tank is usually connected to the trap bag by binding. This connection method is easy to fall off, thus affecting the trapping effect.

[0003] To address the aforementioned issues, a support frame is installed inside the tank. A sealing plate is positioned at the top of the frame, with positioning holes on the plate. A filter bag is fitted into these positioning holes, and the filter bag utilizes an internal support mesh structure to prevent deformation. A support ring is installed inside the filter bag, which presses the filter bag against the inner wall of the positioning hole. However, due to the strong vacuum suction, the top of the filter bag is prone to deformation, creating a gap between the outer wall of the filter bag and the positioning hole. This gap prevents dust particles in the gas or vapor molecules from being filtered out, easily clogging the condenser.

[0004] Therefore, this utility model provides a vacuum collector for drying and preventing leakage of refined sterols. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a vacuum collector for drying refined sterols to prevent leakage, so as to solve the problems mentioned in the background art. This utility model has the advantage of preventing leakage by squeezing and positioning the mouth of the collection filter bag.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a vacuum trap for drying and preventing leakage of refined sterols, comprising a tank and a trapping filter bag located inside the tank. The top opening of the tank is provided with a cap, the bottom of the tank is fixedly connected to an inlet pipe, and the outer wall of the tank is fixedly connected to an outlet pipe near the top. A skeleton is provided inside the tank, the skeleton including a positioning sealing plate located at the top. The outer peripheral wall of the positioning sealing plate is fixedly and sealed to the inner wall of the tank. The positioning sealing plate has several circumferentially distributed positioning holes, and the trapping filter bag is sealed and fitted inside the positioning holes. A pressure plate is provided inside the tank, located above the positioning sealing plate and lower than the outlet pipe. The bottom of the pressure plate abuts against the top of the trapping filter bag, and an opening is provided on the surface of the pressure plate opposite to the inlet of the trapping filter bag.

[0007] Furthermore, the trapping filter bag is provided with a support ring near the top opening, and the positioning hole is equal to the outer diameter of the trapping filter bag.

[0008] Furthermore, the number of positioning holes is four, and they are evenly distributed around the circumference of the tank.

[0009] Furthermore, the inner diameter of the opening is less than or equal to the inner diameter of the trapping filter bag.

[0010] Furthermore, a screw is fixedly connected to the center of the top of the positioning sealing plate, a nut is screwed onto the screw, and a clearance hole with a gap is opened in the center of the pressure plate and fitted outside the screw.

[0011] Furthermore, the outer peripheral wall of the positioning sealing plate and the inner peripheral wall of the tank are welded together.

[0012] Furthermore, the trapping filter bag has a structure with an internal supporting steel mesh.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, a positioning sealing plate is set inside the tank, and a positioning hole for limiting the top of the capture filter bag is opened on the positioning sealing plate. Then, a support ring is set inside the capture filter bag. Finally, a pressure plate for squeezing and positioning the top opening of the capture filter bag is set above the positioning sealing plate. This prevents the top opening of the capture filter bag from deforming due to negative pressure, thereby ensuring the sealing of the connection between the capture filter bag and the positioning hole and preventing the problem of clogging the pipeline of the subsequent condenser equipment due to filter leakage.

[0015] 2. In this utility model, a screw is fixedly installed in the middle of the top of the positioning sealing plate, and then a nut is screwed on the screw. A clearance hole is opened in the middle of the pressure plate and fitted outside the screw, which makes it more convenient to disassemble and assemble the pressure plate. After opening the cover, the pressure plate can be removed and the filter bag can be cleaned directly or taken out for cleaning, which has the advantage of making it more convenient to clean the filtered debris.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1 to 3 This utility model provides a technical solution: a vacuum trap for drying and preventing leakage of refined sterols, including a tank 1 and a trapping filter bag 2 located inside the tank 1. The trapping filter bag 2 is a cylindrical structure with an internal supporting steel mesh to ensure its shape. A cover 7 is provided at the top opening of the tank 1, and the cover 7 is hinged to the tank 1. Several surrounding clamping bolt assemblies are hinged to the bottom of the tank 1. The clamping bolt assemblies are used to squeeze and seal the top opening of the tank 1. An inlet pipe 11 is fixedly connected to the bottom of the tank 1. The inlet pipe 11 is the channel for gas, vapor and impurities to enter the tank 1. An outlet pipe 12 is fixedly connected to the outer wall of the tank 1 near the top. The outlet pipe 12 is the channel for the filtered gas to exit the tank 1. The trapping filter bag 2 is used to filter out impurities (such as vapor molecules, dust, etc.) to prevent impurities from entering the subsequent condensation pipe.

[0022] The tank body 1 contains a frame 3 for positioning the filter bags 2. The frame 3 includes a positioning sealing plate 31 at the top. The outer peripheral wall of the positioning sealing plate 31 is fixedly and sealed to the inner wall of the tank body 1. Specifically, the outer peripheral wall of the positioning sealing plate 31 and the inner peripheral wall of the tank body 1 are welded together. The positioning sealing plate 31 has several circumferentially distributed positioning holes 311. The filter bags 2 are sealed inside the positioning holes 311. One filter bag 2 is installed in each positioning hole 311. The function of the positioning holes 311 is to prevent the filter bags 2 from tilting.

[0023] In this embodiment, a support ring 5 is provided inside the filter bag 2 near the top opening. The support ring 5 is a spring steel ring with a non-closed-loop structure. The positioning hole 311 and the outer diameter of the filter bag 2 are equal. The support ring 5 uses elasticity to press the filter bag 2 against the inner wall of the positioning hole 311, thereby improving the sealing between the filter bag 2 and the positioning hole 311.

[0024] In this technical solution, a pressure plate 4 is provided inside the tank 1, located above the positioning sealing plate 31 and lower than the outlet pipe 12. The bottom of the pressure plate 4 abuts against the top of the collection filter bag 2. When the lower end face of the pressure plate 4 squeezes the top opening of the collection filter bag 2, the shape of the top opening of the collection filter bag 2 will be limited and fixed, so that the top opening of the collection filter bag 2 will not deform, and thus there will be no leakage of debris. The plate surface of the pressure plate 4 is provided with a through-hole 41 opposite to the inlet of the collection filter bag 2. Preferably, the inner diameter of the through-hole 41 is less than or equal to the inner diameter of the collection filter bag 2. The through-hole 41 allows gas to flow through the collection filter bag 2, ensuring normal vacuum collection function.

[0025] Furthermore, a screw 312 is fixedly connected to the middle of the top of the positioning sealing plate 31, and a nut 6 is screwed onto the screw 312. A clearance hole 42 is opened in the middle of the pressure plate 4, which is fitted outside the screw 312. The outer diameter of the positioning sealing plate 31 is smaller than the inner diameter of the tank 1. After removing the nut 6, the positioning sealing plate 31 can be easily removed, which is convenient for cleaning the collection filter bag 2.

[0026] Working principle: During the vacuum collection process, the gas containing impurities enters through the inlet pipe 11, and the air that has been collected and filtered by the collection filter bag 2 is discharged through the outlet pipe 12. During this process, due to the limiting effect of the positioning hole 311 on the positioning sealing plate 31 on the collection filter bag 2, the squeezing effect of the support ring 5, and the squeezing effect of the pressure plate 4 on the top opening of the collection filter bag 2, the opening of the collection filter bag 2 will not deform. This ensures that the collection filter bag 2 and the positioning hole 311 are sealed together, preventing material leakage during collection.

[0027] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
