Description

Technical Field

[0001] This utility model belongs to the field of evaporation crystallization technology, specifically relating to a low-temperature evaporation crystallization device with an anti-clogging structure. Background Technology

[0002] In industries such as chemical, pharmaceutical, and food processing, low-temperature evaporation crystallization is a commonly used separation and purification method. This technology involves creating a vacuum inside the equipment, allowing the solution to boil and evaporate at a lower boiling point, causing the solute to precipitate as crystals, thus separating the solute from the solvent. The performance of the low-temperature evaporation crystallization equipment, as the key device in realizing this technology, directly affects product quality and production efficiency.

[0003] However, since a large amount of crystals are generated during the evaporation and crystallization process, the crystals are usually discharged through the discharge pipe. However, the crystals tend to adhere to the inner wall of the discharge pipe, causing accumulation and blockage, which makes cleaning work more troublesome. Therefore, the applicant proposes a low-temperature evaporation and crystallization device with an anti-blockage structure to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a low-temperature evaporation crystallization device with an anti-clogging structure, which aims to improve the problem that crystals easily adhere to the inner wall of the discharge pipe, causing accumulation and blockage, and bringing more trouble to the cleaning work.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A low-temperature evaporation crystallization device with an anti-clogging structure includes:

[0007] An evaporator and a scraping mechanism assembled inside the evaporator, and a discharge mechanism assembled on one side of the evaporator;

[0008] The scraping mechanism includes a rotating rod rotatably installed inside the evaporator, the rotating rod extending out of one side of the evaporator, and a cam frame slidably installed around the rotating rod and on one side of the evaporator.

[0009] The discharge mechanism includes a valve seat connected to one side of the evaporator. A movable frame corresponding to the cam frame is hinged to the rear end of the valve seat. A valve is slidably installed inside the valve seat. A discharge pipe is connected to the bottom of the valve seat through a flexible hose. A fixing frame is fixedly installed at the bottom of the valve seat and on the periphery of the discharge pipe. A vibration spring is connected between the fixing frame and the outer wall of the discharge pipe.

[0010] Preferably, a heating cover is fixedly installed at the bottom of the evaporator, and a heating tube is fixedly connected inside the heating cover.

[0011] Preferably, a feed pipe is connected to one side of the evaporator, and an exhaust pipe and a vacuum pipe are connected to the top of the evaporator.

[0012] Preferably, a motor corresponding to the rotating rod is fixedly installed on one side of the evaporator, and the rotating rod and the cam frame are slidably installed through a sliding groove.

[0013] Preferably, a stirring rack is connected to the periphery of the rotating rod and inside the evaporator, and multiple scrapers that fit against the inner wall of the evaporator are fixedly installed on the stirring rack.

[0014] Preferably, a thrust spring is fixedly connected between the movable frame and the valve seat, and a roller corresponding to the cam frame is rotatably mounted on the top of the movable frame.

[0015] Preferably, an electric push rod corresponding to the valve is fixedly installed on one side of the valve seat, and a limiting bracket extending out of the valve and engaging with the cam frame is fixedly installed on the top of the valve.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] (1) This utility model is equipped with a discharge mechanism, which can automatically drive the cam frame to move and correspond to the movable frame when the valve is opened. The rotation of the rotating rod can drive the cam frame to rotate and squeeze the movable frame. After the movable frame is squeezed, it can flip and hit the discharge pipe. Through the action of the vibration spring, the discharge pipe can generate high frequency vibration, which can prevent the crystals from adhering to the inner wall of the discharge pipe. At the same time, it can shake off the crystals adhering to the inner wall of the discharge pipe, which can effectively avoid the accumulation of crystals and can more easily achieve the anti-blocking situation. It also effectively reduces the trouble caused by cleaning.

[0018] (2) The present invention has a limit frame on the top of the valve, which can be engaged with both sides of the cam frame. When the valve is opened, the movement of the valve can drive the limit frame to move synchronously, which can easily move the cam frame to correspond with the movable frame. When feeding, the movable frame can be triggered to strike and vibrate the feeding pipe. When the valve is closed, the cam frame can be separated from the movable frame. When feeding is not required, the movable frame can be prevented from striking the feeding pipe, which brings more convenience to the user. Attached Figure Description

[0028] Example 1:

[0029] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a low-temperature evaporation crystallization device with an anti-clogging structure includes:

[0030] Evaporator 1 and scraping mechanism 3 assembled inside evaporator 1, and discharge mechanism 2 assembled on one side of evaporator 1;

[0031] The scraping mechanism 3 includes a rotating rod 32 rotatably installed inside the evaporator 1, the rotating rod 32 extending out of one side of the evaporator 1, and a cam frame 36 slidably installed on the periphery of the rotating rod 32 and on one side of the evaporator 1.

[0032] The discharge mechanism 2 includes a valve seat 21 connected to one side of the evaporator 1. A movable frame 22 corresponding to the cam frame 36 is hinged to the rear end of the valve seat 21. A valve 29 is slidably installed inside the valve seat 21. A discharge pipe 23 is connected to the bottom of the valve seat 21 through a hose 211. A fixing frame 24 is fixedly installed at the bottom of the valve seat 21 and on the periphery of the discharge pipe 23. A vibration spring 25 is connected between the fixing frame 24 and the outer wall of the discharge pipe 23.

[0033] As can be seen from the above, when using this device, it is placed in a suitable position. By introducing the solution to be processed into the evaporator 1, the vacuum pump is used to evacuate the evaporator 1, which can lower the boiling point of the solution. By heating the evaporator 1, the solution boils and evaporates, producing crystals that remain inside the evaporator 1. When it is necessary to remove the crystals, by moving the valve 29 to the right along the inside of the valve seat 21, the valve seat 21 can be connected to the evaporator 1, and the crystals can be introduced through the valve seat 21 into the discharge pipe 23 for discharge.

[0034] When valve 29 moves to the right, it drives cam frame 36 to slide along rotating rod 32, which in turn moves cam frame 36 to correspond with movable frame 22. The rotation of rotating rod 32 drives cam frame 36 to rotate, which can squeeze movable frame 22. After being squeezed by movable frame 22, it can flip over, and when movable frame 22 returns to its original position, it can strike the outer wall of feed pipe 23. Through the elastic action of vibration spring 25, feed pipe 23 can be vibrated at high frequency, making it difficult for crystals to adhere to the inner wall of feed pipe 23. At the same time, it can shake off the crystals adhering to the inner wall of feed pipe 23, which can effectively prevent accumulation and achieve anti-clogging in a more convenient way, while also effectively reducing the trouble caused by cleaning.

[0035] Depend on Figure 1 and Figure 3 It can be seen that a heating cover 14 is fixedly installed at the bottom of the evaporator 1, and a heating tube 15 is fixedly connected inside the heating cover 14.

[0036] As can be seen from the above, the heating cover 14 is located at the bottom of the evaporator 1, and the heating tube 15 can heat the bottom of the evaporator 1, which can conveniently heat the solution in the evaporator 1 to a boiling state, so that the crystals can precipitate out of the solution.

[0037] For details, please refer to Figure 1 , Figure 2 and Figure 3 As shown, a feed pipe 11 is connected to one side of the evaporator 1, and an exhaust pipe 12 and a vacuum pipe 13 are connected to the top of the evaporator 1.

[0038] As can be seen from the above, the solution to be processed can be easily introduced into the evaporator 1 through the feed pipe 11, and the water vapor generated during the evaporation of the solution can be easily discharged through the vent pipe 12. This allows for easy connection with the condenser, so that the generated water vapor can be cooled into distilled water through the condenser for easy reuse. The vacuum pipe 13 allows for easy connection with the vacuum pump, so that the air in the evaporator 1 can be easily extracted, so that the evaporator 1 is in a vacuum state. This can easily lower the boiling point of the solution and facilitate rapid boiling and evaporation of the solution.

[0039] For details, please refer to Figure 3 , Figure 4 and Figure 5 As shown, a motor 34 corresponding to the rotating rod 32 is fixedly installed on one side of the evaporator 1, and the rotating rod 32 and the cam frame 36 are slidably installed through the slide groove 35.

[0040] As can be seen from the above, the motor 34 can provide power to the rotating rod 32, which can drive the rotating rod 32 to rotate. The slide groove 35 can enable the rotating rod 32 to drive the cam frame 36, and at the same time, the cam frame 36 can slide left and right along the slide groove 35, which facilitates the alignment and disalignment of the cam frame 36 with the movable frame 22.

[0041] Example 2:

[0042] refer to Figure 3 As shown, a stirring rack 31 is connected to the outer periphery of the rotating rod 32 and inside the evaporator 1. Multiple scrapers 33 that are in contact with the inner wall of the evaporator 1 are fixedly installed on the stirring rack 31.

[0043] As can be seen from the above, the rotation of the rotating rod 32 can easily drive the stirring frame 31 to rotate. The stirring frame 31 can be used to stir the solution in the evaporator 1, so that the solution can be heated evenly and evaporate quickly. The spiral rotation of the scraper 33 can directionally push the crystals in the evaporator 1, and push the crystals to the discharge mechanism 2 for discharge. At the same time, the scraper 33 can scrape off the crystals adhering to the inner wall of the evaporator 1 to avoid affecting the operation of the evaporator 1.

[0044] refer to Figure 4 As shown, a thrust spring 27 is fixedly connected between the movable frame 22 and the valve seat 21, and a roller 26 corresponding to the cam frame 36 is rotatably mounted on the top of the movable frame 22.

[0045] As can be seen from the above, when the movable frame 22 is flipped and reset, the thrust of the thrust spring 27 can be used to push the movable frame 22 to reset quickly, so that the movable frame 22 can strike the feed tube 23. When the cam frame 36 contacts the roller 26, the cam frame 36 can be used to press the movable frame 22 smoothly to perform the flipping operation.

[0046] refer to Figure 5 As shown, an electric push rod 28 corresponding to the valve 29 is fixedly installed on one side of the valve seat 21, and a limit bracket 210 extending out of the valve 29 and engaging with the cam frame 36 is fixedly installed on the top of the valve 29.

[0047] As can be seen from the above, the extension and retraction function of the electric push rod 28 can drive the valve 29 to move left and right within the valve seat 21, facilitating opening and closing operations. When the valve 29 moves to the right to open, it can drive the limit frame 210 to move to the right simultaneously. By utilizing the limiting effect of the limit frame 210 on the cam frame 36, the cam frame 36 can be moved to correspond with the movable frame 22. This allows the movable frame 22 to be triggered to strike the feed tube 23 during material feeding. When the valve 29 moves to the left to close, it can drive the cam frame 36 to separate from the movable frame 22, allowing the striking action on the feed tube 23 to be automatically released when material feeding is not required.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
