Description

Technical Field

[0001] The utility model relates to the technical field of liquid concentration and evaporation, in particular to a single-effect concentrator. Background Art

[0002] Single-effect external circulation vacuum concentrator (i.e. single-effect concentrator) is mainly used for the recovery of industrial organic solvents (such as alcohol) in traditional Chinese medicine, western medicine, glucose, brewing, starch, oral liquid, food, chemical industry, etc. It is suitable for low-temperature vacuum concentration of heat-sensitive materials with small batches and many varieties.

[0003] The principle of the single-effect concentrator is: the raw steam enters the outside of the tube array of the heating chamber, heats the feed liquid and rises, sprays it into the evaporation chamber from the nozzle, separates the gas and liquid, and returns the feed liquid from the circulation pipe to the lower part of the heating chamber for reheating, and then sprays it into the evaporation chamber again to start a cycle. The feed liquid is concentrated to a certain degree, and after sampling and confirmation of compliance, it is discharged from the discharge port. The steam evaporated from the evaporation chamber is removed by the defoamer and then passes through the gas-liquid separator. Part of the feed liquid returns to the evaporation chamber, and the remaining secondary steam is cooled into liquid by the condenser and cooler and enters the liquid storage barrel. Finally, the non-condensable gas is discharged into the atmosphere or taken away by the vacuum pump.

[0004] During this process, the foam generated inside the evaporation chamber tends to adhere to the inner wall, which is inconvenient to clean and affects subsequent use.

[0005] In order to solve the above problems, after searching, it was found that the Chinese patent with patent number CN202322010251.5 discloses a single-effect concentrator, which belongs to the technical field of single-effect concentrators, and includes a heating chamber, an evaporation chamber, a defoamer, a condenser, a cooler and a liquid storage barrel that are connected in sequence. A rotating motor is provided on the top of the evaporation chamber, and the output end of the rotating motor extends into the evaporation chamber and is connected to the main rod. A main frame is fixed at the bottom of the main rod, and a side frame is provided at the bottom of the main frame. A scraper is provided on one side of the side frame, and an adjusting mechanism for adjusting the position of the scraper is provided on the main frame. The utility model adjusts the position of the scraper through the adjusting mechanism, so that the scraper is pressed against the inner wall of the evaporation chamber, and the main rod is driven to rotate by the rotating motor, thereby driving the main frame to rotate, and then driving the scraper to rotate, so as to clean the product attached to the inner wall of the evaporation chamber. During the cleaning process, the solvent is sprayed by the cleaning mechanism to process the product on the inner wall of the evaporation chamber, thereby improving the cleaning efficiency of the scraper, improving the purity and yield of the product, and facilitating the cleaning of the equipment.

[0006] However, according to the analysis, the above solution has some problems:

[0007] One end of the liquid guide hose is fixed inside the evaporation chamber, and the other end is fixed to the side frame and connected to the liquid storage chamber of the side frame. However, the side frame will rotate around the main rod, which will cause the hose to be entangled around the outer end of the main rod and eventually be torn off, making it impossible to clean. Utility Model Content

[0008] Therefore, in order to solve the above-mentioned shortcomings, the utility model provides a single-effect concentrator, which sets a cleaning component on the evaporation tank to facilitate timely cleaning of the foam adhered to the inner wall of the evaporation tank and effectively ensure the stability during use.

[0009] The utility model is implemented in this way: a single-effect concentrator is constructed, including an evaporation tank and a heating tank and auxiliary components interconnected by a pipeline, a cleaning component is arranged on the top of the evaporation tank, one end of the cleaning component is inserted into the evaporation tank and contacts with the inner wall of the evaporation tank to perform circular motion to achieve cleaning, the other end of the cleaning component is arranged outside the evaporation tank and maintained coaxially with the evaporation tank, and a power mechanism for driving the cleaning component inside the evaporation tank to move is arranged inside the cleaning component outside the evaporation tank.

[0010] Specifically, the top of the evaporation tank is open and provided with a cover body, a through hole coaxial with the evaporation tank is opened on the cover body, and the cleaning assembly is installed on the cover body.

[0011] Specifically, the cleaning assembly includes a rotating tube, which is installed on the inner wall of the through hole of the cover body through a rotating connector and has one end inserted into the evaporation tank and the other end extending to the outside of the evaporation tank;

[0012] The installation tube is connected vertically with the end of the rotating tube at the inner end of the evaporator and the two ends are symmetrical with respect to the rotating tube;

[0013] A sprinkler head is fixedly mounted on two ends of the mounting pipe;

[0014] Two rotating drums are movably connected to the two ends of the mounting tube through mounting rods to keep the spacing between the two rotating drums and the rotating tube consistent;

[0015] The water inlet pipe is installed on the inner wall of the rotating pipe at the outer end of the evaporator through a rotating connecting piece.

[0016] Specifically, mounting holes are opened in the vertical direction on both ends of the mounting tube, one end of the mounting rod passes vertically downward through the mounting hole, a limiting head is provided at the other end of the mounting rod, an external thread is provided on the outside of the mounting rod at the lower end of the mounting tube, and the mounting rod is fixed by screwing a nut on the external thread of the mounting rod until the end of the thread contacts the outer wall of the mounting tube, and the rotating drum is sleeved on the outside of the mounting rod at the lower end of the mounting tube through a rotating connecting piece.

[0019] The utility model has the following beneficial effects:

[0020] Firstly, the single-effect concentrator is provided with a cleaning component on the evaporation tank, so as to clean the foam adhered to the inner wall of the evaporation tank in time and facilitate subsequent use.

[0021] Secondly, the single-effect concentrator sets the cleaning component to be installed coaxially with the evaporation tank, and can comprehensively clean the inner wall of the evaporation tank through the rotation of the cleaning component, thereby ensuring the cleaning quality.

[0022] Thirdly, the single-effect concentrator can ensure stability during rotation by configuring the cleaning components as two rotating drums that are symmetrical with respect to the rotation center, thereby preventing the stability of the rotating drums from being affected due to being eccentrically configured with respect to the rotation center.

[0023] Finally, the single-effect concentrator can effectively scrape and rinse the foam surface on the inner wall of the evaporator by setting a soft brush on the outer end of the drum and a spray head on the top, further ensuring the cleaning quality. BRIEF DESCRIPTION OF THE DRAWINGS

Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical contents disclosed in the present invention without affecting the effects and purposes that can be achieved by the present invention.

[0034] As described in the background art, during use, the existing single-effect concentrator is prone to produce foam in the evaporation tank and adhere to the inner wall, which makes it difficult to clean it quickly and comprehensively, thus affecting the subsequent concentration of materials.

[0035] Based on the above reasons, the utility model provides a single-effect concentrator, including an evaporation tank 2 and a heating tank 1 and an auxiliary component 4 interconnected by a pipeline 3, a cleaning component is arranged on the top of the evaporation tank 2, one end of the cleaning component is inserted into the evaporation tank 2 and contacts with the inner wall of the evaporation tank 2 to perform circular motion to achieve cleaning, the other end of the cleaning component is arranged outside the evaporation tank 2 and maintained coaxially with the evaporation tank 2, and a power mechanism for driving the cleaning component inside the evaporation tank 2 to move is arranged inside the cleaning component outside the evaporation tank 2.

[0036] Specifically, the auxiliary components 4 are various components of the existing single-effect concentrator, such as a separator, a demister, a vapor-liquid separator, a condenser, a cooler, a liquid storage tank, a circulation pipe, etc., which are conventional equipment in the field and are therefore not shown one by one in this solution.

[0037] Specifically, the top of the evaporation tank 2 is open and provided with a cover 5 , a through hole coaxial with the evaporation tank 2 is opened on the cover 5 , and the cleaning assembly is installed on the cover 5 .

[0038] Specifically, the cleaning assembly includes a rotating tube 6, which is installed on the inner wall of the through hole of the cover body 5 through a rotating connector and keeps one end inserted into the evaporation tank 2 and the other end extending to the outside of the evaporation tank 2;

[0039] The installation tube 10 is vertically connected to the end of the rotating tube 6 at the inner end of the evaporation tank 2 and the two ends are symmetrical with respect to the rotating tube 6;

[0040] The spray head 13 is fixedly mounted on the two ends of the mounting pipe 10;

[0041] Two rotating drums 11 are movably connected to the two ends of the mounting tube 10 through mounting rods 12 to keep the distance between the two rotating drums 11 and the rotating tube 6 consistent;

[0042] The water inlet pipe 9 is installed on the inner wall of the rotating pipe 6 at the outer end of the evaporation tank 2 through a rotating connector.

[0043] According to the technical features described in the previous paragraph, the rotatably mounted water inlet pipe and the spray head are provided to facilitate spraying the inner wall of the evaporation tank through an external water source, thereby cleaning the evaporation tank for subsequent use.

[0044] Please refer to the attached Figure 6 It can be seen that, specifically, mounting holes are opened in the vertical direction on both ends of the mounting tube 10, one end of the mounting rod 12 passes vertically downward through the mounting hole, and a limiting head is provided at the other end of the mounting rod 12. An external thread is provided on the outside of the mounting rod 12 at the lower end of the mounting tube 10 (because the thread lines are dense, for the convenience of display, the thread lines are not shown in the accompanying drawings), and the mounting rod 12 is fixed by screwing a nut on the external thread of the mounting rod 12 until the end of the thread contacts the outer wall of the mounting tube 10, and the rotating drum 11 is sleeved on the outside of the mounting rod 12 at the lower end of the mounting tube 10 through a rotating connecting piece.

[0045] According to the technical features described in the previous paragraph, the connection method of the rotating drum is to facilitate its movable installation at the lower end of the mounting tube, while ensuring a vertical setting so that the outer wall of the rotating drum is close to the outer wall of the evaporator.

[0046] Specifically, soft brushes are evenly arranged on the outer wall of the rotating drum 11 , and the outer ends of the soft brushes are in contact with the inner wall of the evaporation tank 2 .

[0047] According to the technical features described in the previous paragraph, a soft brush is arranged at the outer end of the drum to facilitate scraping the inner wall of the evaporator, thereby scraping off foam and materials.

[0048] Specifically, the power mechanism includes a driving motor 7 and a gear transmission mechanism 8 arranged on the cover body 5, the driving wheel in the gear transmission mechanism 8 is installed on the driving shaft of the driving motor 7, and the driven wheel of the gear transmission mechanism 8 is installed on the outer end of the rotating tube 6.

[0049] According to the technical features described in the previous paragraph, the power mechanism is provided to facilitate driving the cleaning component to rotate, thereby achieving comprehensive cleaning of the inner wall of the evaporator tank.

[0050] The working principle of the single-effect concentrator can refer to the existing single-effect concentrator, which is a conventional technology in the field and will not be described here. Here we mainly describe the cleaning process of the evaporator:

[0051] After all the materials in the evaporation tank 2 are discharged, clean water is transported to the water inlet pipe 9 through an external water source. The clean water enters the rotating tube 6 through the water inlet pipe 9, and then enters the installation tube 10, and then is vertically sprayed onto the inner wall of the evaporation tank 2 through the spray heads 13 at both ends. At the same time, the driving motor 7 is started, and the rotating tube 6 is driven to rotate through the gear transmission mechanism 8, thereby driving the internal installation tube 10 and the rotating drum 11 to rotate around the center of the rotating tube 6. In this process, the soft brush on the outer wall of the rotating drum 11 moves along the inner wall of the evaporation tank 2, and the rotating drum 11 itself rotates (it may not rotate, and if it does not rotate, the rotating drum 11 can be directly fixed to the outside of the installation rod 12), so that the materials and foam on the inner wall of the evaporation tank 2 can be scraped, and the evaporation tank can be quickly cleaned in combination with the clean water sprayed from the upper spray head 12.

[0052] The above description is a detailed description of the preferred feasible embodiment of the utility model, but the embodiment is not used to limit the scope of the patent application of the utility model. All equivalent changes or modified changes completed under the technical spirit suggested by the utility model should fall within the patent scope covered by the utility model.
