Abstract

This invention provides a chemical mixing vessel with anti-adhesion and self-cleaning functions, relating to the field of chemical mixing technology. It includes a tank body with a feed pipe at the top and a motor mounted on the top. A rotating rod is fixedly connected to the motor's output end. A stirring blade and an anti-adhesion mechanism are fixed to the outer wall of the rotating rod. A cleaning mechanism is installed on the inner wall of the tank, and a liquid outlet pipe connects to the bottom of the tank. In this invention, a first spring elastically pushes the movable blades, ensuring that the rubber scraper and branch scraper always adhere to the inner wall of the mixing tank. This prevents material adhesion and clumping from the source, ensuring uniform mixing of chemical materials. It eliminates the need for regular manual cleaning of materials adhering to the inner wall. The reciprocating action of the spring plate and protrusions on the absorbent cotton automatically and evenly distributes the stored cleaning agent onto the inner wall of the tank. Combined with the scraping action of the anti-adhesion mechanism's scraper, residual materials on the inner wall are dissolved, flushed, and self-cleaned. The cleaning waste liquid can be discharged centrally through the liquid outlet and liquid outlet pipe.

Description

Technical Field

[0001] This invention relates to the field of chemical mixing technology, and in particular to a chemical mixing vessel with anti-adhesion and self-cleaning functions. Background Technology

[0002] Chemical mixing tanks are core equipment in the chemical production field used for material mixing, reaction, emulsification, and blending. They are widely used in the raw material mixing and processing of industries such as fine chemicals, coatings, pharmaceuticals, resins, and adhesives. Currently, conventional chemical mixing tanks on the market have significant shortcomings in actual use.

[0003] Firstly, viscous chemical materials such as resins, adhesives, and high-viscosity coatings are highly susceptible to physical adsorption and adhesion to the inner wall of the stirred tank during the reaction process. Conventional stirring blades can only agitate the materials in the middle of the tank and cannot clean the materials adhering to the tank wall in real time. Long-term adhesion of materials can easily lead to drying and clumping, which not only wastes materials but also seriously affects the overall uniformity of the mixing of materials in the tank, reducing the quality of the chemical reaction product. At the same time, manually cleaning the clumped materials on the tank wall is difficult and requires stopping the machine for disassembly and cleaning, which significantly shortens the continuous operation cycle of the equipment and increases labor maintenance costs and production downtime losses.

[0004] Secondly, traditional mixing tanks generally lack a built-in self-cleaning structure. After production, manual hand-held cleaning tools are required to rinse the inner wall of the tank, or external high-pressure cleaning equipment is needed for rinsing. This not only results in low cleaning efficiency and high labor intensity, but also in incomplete cleaning and the existence of cleaning dead corners. In addition, the cleaning agent is mostly poured in at once and cannot be slowly released, resulting in high consumption of chemicals and high energy consumption. Furthermore, the waste liquid generated during cleaning lacks a dedicated diversion and collection structure, which easily accumulates in the dead corners at the bottom of the tank, breeding impurities and contaminating subsequent processed materials. This makes it difficult to meet the requirements of modern chemical continuous, automated, and clean production.

[0005] Therefore, this invention proposes a chemical mixing vessel with anti-adhesion and self-cleaning functions to solve the problems mentioned above. Summary of the Invention

[0006] This invention proposes a chemical mixing vessel with anti-adhesion and self-cleaning functions to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a chemical mixing tank with anti-adhesion and self-cleaning functions, comprising a tank body, a feed pipe provided at the top of the tank body, a motor installed at the top of the tank body, a rotating rod fixedly connected to the output end of the motor, a stirring blade and an anti-adhesion mechanism fixed to the outside of the rotating rod, a cleaning mechanism installed at the top of the rotating rod, and a liquid outlet pipe connected to the bottom of the tank body;

[0008] The anti-adhesion mechanism moves in a circular motion with the rotating rod to scrape off the viscous material adhering to the inner wall of the tank.

[0009] The cleaning mechanism can rotate with the rotating rod, and automatically sprays cleaning agent based on its own rotation and vibration during rotation. The cleaning agent can be sprayed onto the inner wall of the tank under the action of centrifugal force.

[0010] Preferably, the anti-adhesion mechanism includes a movable blade, a rotating shaft, a first fixed plate, a second fixed plate, and a scraper.

[0011] The first fixing plate is fixed to the end of the stirring blade, the second fixing plate is fixed to the end of the movable blade, and the first fixing plate and the second fixing plate are fixed to both sides of the rotating shaft respectively, so that the first fixing plate and the second fixing plate can rotate; a scraper is fixedly connected to the side of the second fixing plate opposite to the movable blade.

[0012] Preferably, a plurality of first springs are arranged parallel to each other between the first fixing plate and the second fixing plate, with one end of the first spring fixed to the first fixing plate and the other end abutting against the second fixing plate.

[0013] Preferably, the first spring is disposed on the back side of the stirring blade in the direction of rotation, so that the end of the moving blade always fits against the inner wall of the tank.

[0014] Preferably, the scraper includes a rubber scraper and a plurality of branch scrapers, the branch scrapers being respectively disposed on both sides of the rubber scraper.

[0015] Preferably, the cleaning mechanism includes a liquid collection box and absorbent cotton, the liquid collection box being fixed to the top of the rotating rod; the liquid collection box has liquid outlets on its left and right sides, and the absorbent cotton is placed inside the liquid collection box and positioned at the liquid outlets.

[0016] Preferably, the cleaning mechanism further includes a spring plate, which is disposed at the liquid outlet, and the absorbent cotton is disposed between the spring plate and the liquid outlet; the spring plate is elastically installed in the liquid collection box by second springs on both sides.

[0017] Preferably, the elastic plate has several protrusions fixed on its surface facing the absorbent cotton.

[0018] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0019] 1. In this invention, the first and second fixing plates are fixed to the outer wall of the rotating rod. The movable blades rotate flexibly through the rotating shaft, and the first spring continuously provides elastic pushing force, ensuring that the rubber scrapers and branch scrapers on the side of the movable blades always adhere tightly to the inner wall of the tank. While the motor drives the rotating rod and stirring blades to stir the material, the anti-adhesion mechanism simultaneously rotates in a circular motion, continuously scraping away viscous chemical materials adhering to the inner wall of the tank, effectively preventing the accumulation, drying, and clumping of high-viscosity materials on the tank wall. This solves the material adhesion problem from the source of operation, ensuring more uniform and thorough mixing of materials in the tank, improving the quality of chemical reactions and stirring processes. It also eliminates the need for manual cleaning of materials adhering to the tank wall, reducing manual operation intensity and downtime maintenance time, extending the continuous operating time of the equipment. It is suitable for stirring and producing various viscous and easily adhering chemical raw materials, demonstrating strong practicality and adaptability.

[0020] 2. In this invention, the absorbent cotton placed inside the liquid collection box effectively absorbs and temporarily stores the cleaning agent, enabling a slow and gradual release of the cleaning agent without the need for frequent manual additions. During the equipment's stirring operation, the centrifugal force and vibration of its own rotation cause the second spring to repeatedly deform, driving the spring plate to bounce back and forth at high frequency. The protrusions on its surface continuously squeeze and beat the absorbent cotton, evenly spraying the internal cleaning agent to cover the entire inner wall of the tank. After the cleaning agent wets and dissolves the residual material on the tank wall, the scraping action of the anti-adhesion mechanism scrapes off the residue, achieving all-round self-cleaning of the inner wall without the need for additional cleaning power equipment, making it energy-saving and efficient. The waste liquid after cleaning flows down the tank wall, collects at the liquid collection box outlet, and is discharged uniformly from the outlet pipe. The waste liquid collection and discharge are orderly, avoiding the accumulation of residual stains, significantly reducing the workload of manual cleaning, and realizing simultaneous operation of the stirring tank and self-cleaning, with a high degree of automation and good cleaning effect.

[0027] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention can also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0029] Reference Figures 1 to 3 The present invention provides an embodiment of a chemical mixing vessel with anti-adhesion and self-cleaning functions, comprising a tank body 1. The tank body 1 is the main supporting frame of the entire mixing vessel, providing a sealed working space for chemical raw material mixing, anti-adhesion descaling and self-cleaning operations, while supporting and installing all functional components on the top and inside, ensuring the overall stable operation of the equipment.

[0030] The top of the tank 1 is fixedly connected to the feed pipe 2, which serves as a channel for feeding chemical raw materials, guiding the raw materials to be smoothly fed into the tank 1 and preventing the raw materials from spilling out during the feeding process.

[0031] A motor 3 is fixedly installed at the top of the tank 1, providing the core driving power for the entire stirring and anti-adhesion mechanism 6. Inside the tank 1, a vertically mounted rotating rod 4 is fixedly connected to the output end of the motor 3, allowing it to rotate at high speed under the drive of the motor 3. This rod simultaneously supports the fixed stirring blades 5 and the anti-adhesion mechanism 6, transmitting rotational power. Stirring blades 5 are fixedly connected to the outer side of the rotating rod 4, rotating synchronously with the rotating rod 4 to agitate and stir the chemical raw materials inside the tank 1, achieving uniform mixing. The stirring blades 5 are arranged in layers along the length of the rotating rod 4, with multiple stirring blades 5 evenly arranged in each layer along the circumference. Figure 3 The image shows five layers of stirring blades 5, with four stirring blades 5 evenly arranged in each layer. The number of layers and the quantity of stirring blades 5 in each layer can be increased or decreased according to actual needs.

[0032] The outer wall of the rotating rod 4 is also fixedly equipped with an anti-adhesion mechanism 6. The anti-adhesion mechanism 6 follows the rotating rod 4 to make a circular motion, scraping off the viscous material adhering to the inner wall of the tank 1 in real time, preventing the material from clumping and adhering from the source, and ensuring the mixing operation effect.

[0033] Inside the tank 1, a cleaning mechanism 7 is fixedly installed at the top of the rotating rod 4. This mechanism stores the cleaning agent. The cleaning mechanism 7 can rotate with the rotating rod 4 and release the cleaning agent slowly during rotation. It can automatically spray the cleaning agent based on the rotation and vibration of the cleaning mechanism 7 itself. The cleaning agent can be sprayed onto the inner wall of the tank 1 under the action of centrifugal force. Together with the anti-adhesion mechanism 6, it completes the dissolution and rinsing of residual materials on the inner wall of the tank 1, thus achieving the self-cleaning function.

[0034] The bottom of the tank 1 is fixedly connected to the liquid outlet pipe 8, which serves as the discharge channel for the material after stirring and the waste liquid after cleaning, and discharges the medium to the outside of the tank 1.

[0035] Specifically, such as Figure 3 As shown, the anti-adhesion mechanism 6 includes a movable blade 61, a first spring 63, a rotating shaft 64, a first fixing plate 65, a second fixing plate 66, and a scraper. The first fixing plate 65 is fixed to the end of the stirring blade 5, and the second fixing plate 66 is fixed to the end of the movable blade 61. The first fixing plate 65 and the second fixing plate 66 are fixed to both sides of the rotating shaft 64, so that the first fixing plate 65 and the second fixing plate 66 can rotate, thereby providing a rotational support fulcrum for the movable blade 61, so that the movable blade 61 can rotate and be sleeved on the outer wall of the rotating shaft 64, and can flexibly swing around the rotating shaft 64 to adjust the angle.

[0036] Multiple first springs 63 are arranged parallel to each other between the first fixed plate 65 and the second fixed plate 66. One end of each first spring 63 is fixed to the first fixed plate 65, and the other end abuts against the second fixed plate 66, continuously providing an elastic pushing force to the second fixed plate 66. Specifically, the first springs 63 are located on the back side of the stirring blade 5 in the direction of rotation, thereby ensuring that the end of the movable blade 61 always adheres to the inner wall of the tank 1. Figure 3 The stirring blade 5 rotates clockwise, and the first spring 63 is located on the right side of the rotating shaft 64.

[0037] A scraper is fixedly connected to one end of the second fixed plate 66 opposite to the movable blade 61. The scraper includes a rubber scraper 62 and multiple branch scrapers 67, both of which are in contact with the inner wall of the tank 1 and move in a circular motion synchronously with the movable blade 61, continuously scraping and removing viscous materials and agglomerated impurities adhering to the inner wall of the tank 1. The branch scrapers 67 are respectively arranged on both sides of the rubber scraper 62. One branch scraper 67 is arranged on both sides of the rubber scraper 62 at the end of the stirring blade 5 in the top and bottom layers, and two branch scrapers 67 are arranged on both sides of the rubber scraper 62 at the end of the stirring blade 5 in the middle layer.

[0038] A polytetrafluoroethylene-nano silica composite coating can be sprayed onto the surfaces of the stirring blade 5 and the moving blade 61. Simultaneously, a micron-level diamond-shaped groove array is processed on the material-facing surface of the stirring blade 5. The composite coating reduces surface energy and decreases material physical adsorption, while the diamond-shaped grooves trap a small amount of air to form an air film, further preventing direct contact between the material and the metal surface. Figure 4 and 5 As shown, the cleaning mechanism 7 includes a liquid collection box 71, a spring plate 72, absorbent cotton 74, a protrusion 75, and a second spring 76. The liquid collection box 71 is fixedly installed on the top of the rotating rod 4 and is used to collect and store the cleaning agent for cleaning, providing a mounting carrier for the internal cleaning components. The left and right sides of the liquid collection box 71 are provided with liquid outlets 73. The absorbent cotton 74 is placed inside the liquid collection box 71 and is located at the position of the liquid outlet 73. It can absorb and temporarily store the cleaning agent to achieve slow and gradual liquid release.

[0039] A spring plate 72 is elastically mounted on the inner side of the liquid collection box 71 via a second spring 76. The spring plate 72 is positioned at the liquid outlet 73, and absorbent cotton 74 is disposed between the spring plate 72 and the liquid outlet 73. The second spring 76 is located on both sides of the spring plate 72, respectively contacting the inner wall of the liquid collection box 71. The second spring 76 undergoes reciprocating deformation due to the centrifugal force and vibration generated by the operation of the equipment, driving the spring plate 72 to reciprocate at a high frequency.

[0040] Several protrusions 75 are fixed on the surface of the spring plate 72 facing the absorbent cotton 74. The protrusions 75 move synchronously with the spring plate 72, which can continuously squeeze and beat the absorbent cotton 74, and evenly squeeze and spray the adsorbed cleaning agent onto the entire inner wall surface of the tank 1.

[0041] In addition, corrugated dust covers are fitted over the first spring 63 and the second spring 76. These dust covers are made of acid and alkali resistant rubber. The corrugated dust covers prevent material dust from entering the spring and causing corrosion and jamming, thus extending the spring's service life. The labyrinth-type sealing ring prevents material from entering the shaft mating surface, ensuring smooth shaft rotation.

[0042] The working principle of the entire equipment is as follows: the material is put into the tank 1 through the feed pipe 2, the motor 3 is started, the motor 3 drives the rotating rod 4 to rotate at high speed, the rotating rod 4 drives the stirring blade 5 to rotate synchronously, and uniformly stirs and mixes the chemical raw materials inside the tank 1. At the same time as the rotating rod 4 rotates, it drives the anti-adhesion mechanism 6 to rotate synchronously. The first fixed plate 65 and the second fixed plate 66 are fixed on the outer wall of the rotating rod 4. The rotating shaft 64 is assembled between the two sets of fixed plates. The movable blade 61 can swing flexibly through the rotating shaft 64. The first spring 63 provides elastic pushing force for the movable blade 61, so that the movable blade 61 always sticks to the inner wall of the tank 1. The movable blade 61 is equipped with a rubber scraper 62 and a branch scraper 67 on the side, which continuously scrapes off the viscous material adhering to the inner wall of the tank 1 as the rotating rod 4 rotates, preventing the material from clumping and adhering from the reaction source, and ensuring the stirring effect.

[0043] After the stirring is completed, cleaning agent can be added to the liquid collection box 71 in the cleaning mechanism 7. The liquid collection box 71 is fixedly installed on the inner wall of the tank 1. The liquid collection box 71 is used to store the cleaning agent. The cleaning agent flows in from the opening of the liquid collection box 71 and seeps into the absorbent cotton 74, where it is temporarily absorbed and stored. The spring plate 72 is elastically installed inside the liquid collection box 71 by the second spring 76. The surface of the spring plate 72 is provided with protrusions 75. As the motor 3 drives the stirring blade 5 to rotate continuously, the equipment rotates... The centrifugal force and vibration generated by the rotation will cause the second spring 76 to deform, causing the spring plate 72 to bounce back and forth. The protrusion 75 continuously squeezes and beats the absorbent cotton 74, evenly distributing the cleaning agent adsorbed inside the absorbent cotton 74 to the entire inner wall surface of the tank 1. After the cleaning agent covers the inner wall of the tank, it works in conjunction with the scraping action of the rubber scraper 62 and the branch scraper 67 to dissolve and wash the residual material on the inner wall of the tank. The dissolved waste liquid flows down the inner wall of the tank, and after being collected at the bottom of the tank 1, it is discharged out of the tank 1 through the liquid outlet pipe 8.

[0044] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
