Description

Technical Field

[0001] This utility model belongs to the field of buffer tank mixing technology, specifically relating to a mother liquor anti-crystallization buffer tank. Background Technology

[0002] In industrial production processes such as chemical, pharmaceutical, and metallurgical industries, mother liquor, as an intermediate or by-product of the production process, is crucial for production efficiency and product quality through stable storage and subsequent processing. However, most mother liquors, due to their complex composition and high solute concentration, are easily affected by factors such as temperature changes and prolonged standing time during storage, resulting in solute crystallization.

[0003] According to the authorized announcement number CN211189950U, a stirring tank for the production of culture medium buffer solution is known prior art. Although this patent uses jacketed steam heating to replace traditional electric heating rod heating, which provides uniform heating and scrapes off the material adhering to the inner wall of the stirring tank to ensure full participation in the stirring, it can only mix and stir the material at a single height. This can easily cause the material inside the tank to separate into layers, failing to cover the entire upper and lower areas of the tank. Consequently, the mother liquor near the bottom and walls of the tank will crystallize and precipitate due to stirring. Utility Model Content

[0004] The purpose of this utility model is to provide a mother liquor anti-crystallization buffer tank to solve the problem that it can only mix materials at a single height, which easily causes the materials in the tank to separate into layers and cannot cover the entire upper and lower area of ​​the tank, resulting in the formation of crystal precipitation of mother liquor at the bottom and near the tank wall due to stirring.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mother liquor anti-crystallization buffer tank, comprising a buffer tank body, a turntable rotatably connected to the top of the inner part of the buffer tank body, a fixed shaft fixedly connected to the center of the bottom end of the turntable, and a stirring assembly being raised and lowered on the outside of the fixed shaft; The stirring assembly includes a lifting frame, a sliding sleeve fixedly connected to the lifting frame, the sliding sleeve being slidably installed on the outside of a fixed shaft, a stirring plate being provided on the outside of the lifting frame, a tapered opening being communicated at the bottom end of the sliding sleeve, and a solid hemisphere being fixedly connected to the lifting frame.

[0006] In a preferred embodiment, a connecting rod is fixedly connected to one side of the lifting frame, and a scraper is fixedly connected to the end of the connecting rod away from the lifting frame. One side of the scraper is attached to the inner wall of the buffer tank.

[0007] In a preferred embodiment, the buffer tank is provided with a top cover, the turntable is rotatably connected to the bottom of the top cover, a support frame is fixedly connected to the top of the top cover, a drive motor is fixedly connected to the top of the support frame, and the drive shaft of the drive motor is fixedly connected to the center of the turntable.

[0008] In a preferred embodiment, a waterproof electric push rod is fixedly connected between the bottom end of the turntable and the top end of the lifting frame, a storage battery is installed inside the turntable, and a charging port is provided at the top end of the turntable.

[0009] In a preferred embodiment, the radius of the bottom end of the tapered opening gradually decreases, and the tapered opening is slidably mounted on the outside of the fixed shaft.

[0010] In a preferred embodiment, the top of the cover is provided with multiple input ports, and the bottom ends of the multiple input ports are connected to the inside of the buffer tank.

[0011] In a preferred embodiment, the bottom of the buffer tank is fixedly connected to multiple support legs, and the center of the bottom of the buffer tank is connected to a discharge port, which is equipped with a solenoid valve.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This mother liquor anti-crystallization buffer tank achieves thorough mixing and crystal breakage of the mother liquor throughout its entire range through a dual stirring mode of "rotational stirring + lifting stirring" combined with a solid hemispherical crystal breaking structure. The lifting motion of the stirring plate covers the entire height of the tank, preventing concentration differences between the upper and lower layers of mother liquor; the solid hemisphere can effectively break up initial crystallization particles and prevent crystal agglomeration; the conical inlet and scraper clean the fixed shaft and tank wall in real time, respectively, blocking the formation and adhesion path of crystals from multiple dimensions, significantly improving the anti-crystallization effect and ensuring the quality of mother liquor storage.

[0013] This mother liquor anti-crystallization buffer tank features a scraper that fits tightly against the tank wall and can move up and down with the lifting frame, enabling comprehensive cleaning of the tank wall without dead angles and preventing crystals from accumulating on the tank wall. The conical opening can automatically clean the attached material on the surface of the fixed shaft as it moves up and down with the lifting frame, eliminating the need for manual disassembly and cleaning and reducing the workload of equipment maintenance.

[0014] This mother liquor anti-crystallization buffer tank uses a battery to power a waterproof electric actuator. Combined with a waterproof motor and a sealing structure, it enables the equipment to operate without external power cords, avoiding the risk of mother liquor leakage caused by poor sealing of traditional external power cords.

[0017] The present invention will be further described below with reference to the embodiments.

[0018] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0019] This utility model provides a mother liquor anti-crystallization buffer tank, which achieves full-area stirring of mother liquor, efficient crystallization and crushing within the tank by means of a liftable stirring component, scraper 13, crystallization crushing structure and sealing drive design.

[0020] like Figure 1 and Figure 2 As shown, it includes a buffer tank 1, a turntable 6 is rotatably connected to the top of the inside of the buffer tank 1, a fixed shaft 11 is fixedly connected to the center of the bottom end of the turntable 6, and a stirring assembly is raised and lowered on the outside of the fixed shaft 11. In this embodiment, the buffer tank 1 is integrally welded from 304 stainless steel, and the inner wall is polished to effectively reduce the adhesion probability of mother liquor and crystals. The connection between the turntable 6 and the bottom of the top cover adopts a sealing structure of deep groove ball bearing and skeleton oil seal to prevent mother liquor from seeping into the bearing and affecting the rotation accuracy.

[0021] like Figure 1 and Figure 2 As shown, the top of the buffer tank 1 is provided with a top cover, the turntable 6 is rotatably connected to the bottom of the top cover, the top of the top cover is fixedly connected to a support frame 4, the top of the support frame 4 is fixedly connected to a drive motor 3, and the drive shaft of the drive motor 3 is fixedly connected to the center of the turntable 6.

[0022] In this embodiment, the top cover of the buffer tank 1 is connected to the tank flange with bolts. A double-layer rubber sealing gasket is installed at the connection. The inner layer is made of oil-resistant nitrile rubber and the outer layer is a silicone sealing ring to achieve double sealing and prevent the mother liquor from evaporating and being contaminated by the outside. The drive shaft of the drive motor 3 is connected to the turntable 6 with a keyway fit. An external stainless steel waterproof cover is installed. The waterproof cover and the top cover use an existing sealing structure (such as a rubber gasket) to completely block the mother liquor leakage path and protect the safe operation of the drive motor 3.

[0023] like Figure 2 and Figure 4 As shown, the stirring assembly includes a lifting frame 8, a sliding sleeve 9 is fixedly connected to the lifting frame 8, the sliding sleeve 9 is slidably installed on the outside of the fixed shaft 11, a stirring plate 10 is provided on the outside of the lifting frame 8, a conical opening 15 is connected to the bottom end of the sliding sleeve 9, and a solid hemisphere 14 is fixedly connected to the lifting frame 8.

[0024] In this embodiment, the lifting frame 8 is made of high-strength aluminum alloy die casting, the sliding sleeve 9 is made of brass, and the inner hole is inlaid with a graphite self-lubricating bushing to ensure smooth lifting and no obvious shaking. The conical opening 15 at the bottom of the sliding sleeve 9 is made of polytetrafluoroethylene, and the inner wall is provided with a spiral guide groove. The conical opening 15 and the fixed shaft 11 form an interference fit, which can closely fit the shaft surface during the lifting process and thoroughly scrape off the attached mother liquor and crystals. The solid hemisphere 14 ensures that it can fully cover the stirring area when rotating, effectively colliding and breaking the crystal particles.

[0025] like Figure 2 and Figure 3 As shown, the bottom radius of the tapered opening 15 gradually decreases. The tapered opening 15 is slidably installed on the outside of the fixed shaft 11. During the sliding process, the contact pressure between the tapered opening 15 and the fixed shaft 11 is achieved by the gravity of the sliding sleeve 9 and the tension of the lifting frame 8, which ensures the scraping force without causing excessive wear on the shaft.

[0026] A connecting rod 12 is fixedly connected to one side of the lifting frame 8, and a scraper 13 is fixedly connected to the end of the connecting rod 12 away from the lifting frame 8. One side of the scraper 13 is attached to the inner wall of the buffer tank 1.

[0027] In this embodiment, when the equipment is running, the scraper 13 rotates and rises and falls synchronously with the lifting frame 8, which can efficiently scrape off the material attached to the tank wall without increasing energy consumption due to excessive speed.

[0028] like Figure 3 and Figure 4 As shown, a waterproof electric push rod 7 is fixedly connected between the bottom of the turntable 6 and the top of the lifting frame 8, and a charging connection port is provided at the top of the turntable 6.

[0029] In this embodiment, the battery inside the turntable 6 is a lithium iron phosphate battery, and the charging and discharging method of the battery adopts existing publicly available technical means, which will not be described in detail here. The charging port at the top of the turntable 6 adopts a waterproof aviation plug. When charging, you only need to insert the plug without disassembling any parts, which is convenient to operate. In order to facilitate monitoring of battery power, the top of the turntable 6 is also equipped with a power indicator light to display the remaining power in real time, so as to avoid the equipment operation being affected by insufficient power.

[0030] like Figure 1 and Figure 2As shown, the top of the cover is provided with multiple inlet ports 5, the bottom of the multiple inlet ports 5 are connected to the inside of the buffer tank 1, the bottom of the buffer tank 1 is fixedly connected with multiple support legs 2, and the bottom center of the buffer tank 1 is connected to a discharge port. The discharge port is equipped with a solenoid valve to facilitate connection to the conveying pipeline and reduce the risk of leakage during the mother liquor conveying process.

[0031] Working principle: The stirring component can lift and lower the interior of the buffer tank 1 to stir and mix materials at different heights inside the buffer tank 1. At the same time, the scraper 13 on one side of the stirring component can clean the buffer tank 1 to prevent material residue. It can also lift and lower with the stirring component to clean the inner wall at different heights. Lowering the height of the scraper 13 reduces resistance.

[0032] Driven by the waterproof electric push rod 7, the sliding sleeve 9 and the conical opening 15 can slide and rise on the outside of the fixed shaft 11. The material on the fixed shaft 11 can be scraped off through the narrowed opening at the bottom of the conical opening 15. At the same time as the stirring component rotates, the crystalline particles can be broken up by the collision between the solid hemisphere 14 and the material.

[0033] In the above scheme, it should be noted that: the waterproof electric push rod 7, the drive motor 3 and the battery in this application are all existing products, and the specific structure, electrical connection method (circuit layout) and working principle of the waterproof electric push rod 7, the drive motor 3 and the battery are all existing publicly disclosed technical means. It should also be noted that the waterproof electric push rod 7 and the drive motor 3 of this application are both connected to the battery, and the operator can manually start and stop the waterproof electric push rod 7 and the drive motor 3 one by one.

[0034] 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 of the present invention, the scope of which is defined by the appended claims and their equivalents.
