Description

Technical Field

[0001] This utility model belongs to the field of agitator technology, specifically relating to a chain agitator for stirring liquids in small-mouthed containers. Background Technology

[0002] Agitators are undoubtedly crucial and indispensable pieces of machinery in industrial production. Leveraging their unique mechanical movement, they exhibit powerful functionality, capable of mixing, stirring, dispersing, and dissolving liquids, solids, or gases. In the chemical industry, they facilitate the thorough blending of various chemical reagents, promoting efficient chemical reactions; in the food industry, they ensure uniform mixing of raw materials, guaranteeing the taste and quality of food; in the pharmaceutical industry, they aid in the precise formulation of drug components, ensuring the safety and efficacy of medicines; in the environmental protection field, they promote the full reaction between wastewater and chemicals, helping wastewater treatment meet standards; in the construction industry, they ensure the uniform mixing of building materials, improving construction quality. It can be said that agitators play a vital role in numerous industries.

[0003] Its core value lies in its ability to facilitate full contact between different materials through its own operation, achieving a uniform mixing effect. This uniform mixing not only accelerates the chemical reaction process but also makes the various properties of the product more stable, thereby improving the quality of the final product.

[0004] However, in practical applications, agitators also face some challenges. The agitator's impeller needs to penetrate deep into the liquid for mixing, but the containers vary in size, ranging from large to small. When mixing liquids in small-diameter containers, the impeller's size cannot be flexibly adjusted, making it difficult for the agitator rod to properly extend into the container and perform the mixing work. This affects mixing efficiency and effectiveness, and also causes some inconvenience to production. Utility Model Content

[0005] The purpose of this invention is to provide a chain agitator for stirring liquids in small-mouthed containers. This addresses the problem in existing technologies where the agitator's impeller needs to penetrate deep into the liquid for stirring, but the containers have varying diameters, ranging from large to small. When stirring liquids in small-mouthed containers, the impeller size cannot be flexibly adjusted, making it difficult for the agitator rod to properly extend into the container, thus affecting stirring efficiency and effectiveness, and causing inconvenience to production.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a chain-type stirrer for stirring liquids in small-mouthed containers, comprising a stirring rod, a mounting block at the bottom end of the stirring rod, a stirring chain connected to the surface of the mounting block, a connecting block connected to the top surface of the mounting block, the stirring rod being welded to the connecting block, a stirring motor at the top end of the stirring rod, a mounting column connected to the output shaft of the stirring motor, a handle connected to the surface of the stirring motor, a tenon-and-mortise connection between the mounting column and the stirring rod, a circular block fixedly connected to the surface of the mounting column, a movable block at the bottom end of the circular block, two symmetrical bolts connected to the top end of the movable block, nuts threaded onto the surface of the bolts, a screw threaded through the surface of the movable block, and an arc-shaped scraper on the inner wall of the movable block.

[0007] As a preferred embodiment of the chain-type agitator for stirring liquids in small-mouthed containers according to this utility model, the arc-shaped scraper can be detachably and fixedly connected to the movable block by screws.

[0008] As a preferred embodiment of the chain-type agitator for stirring liquids in small-mouthed containers according to this utility model, the inner arc of the arc-shaped scraper is in contact with the outer wall of the stirring rod.

[0009] As a preferred embodiment of the chain-type agitator for stirring liquids in small-mouthed containers according to this utility model, the movable block can be detachably and fixedly connected to the circular block by means of nuts and bolts, and the outer diameter of the circular block and the movable block are the same.

[0010] As a preferred embodiment of the chain stirrer for stirring liquids in small-mouthed containers according to this utility model, a storage box is installed on the surface of the stirring motor, a baffle plate is inserted into the front end of the storage box, a rectangular block is connected to the front end of the storage box, a guide rod is installed inside the rectangular block, a spring and a fixing block are sleeved on the surface of the guide rod, and a lever is connected to the front end of the fixing block.

[0011] As a preferred embodiment of the chain-type stirrer for stirring liquids in small-mouthed containers according to this utility model, the fixed block can be elastically linked with the rectangular block through a guide rod, a spring, and a lever.

[0012] As a preferred embodiment of the chain stirrer for stirring liquids in small-mouthed containers according to this utility model, the end of the fixing block near the baffle plate is in the shape of an "L", and the surface of the baffle plate is provided with an opening that matches the fixing block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By utilizing the interlocking relationships between the mounting blocks, docking blocks, stirring chain, and stirring rod, a stirring chain replaces the traditional stirring paddle. In actual operation, the stirring chain requires the rotation of the stirring rod to unfold and perform its stirring function. Thus, when the stirring rod is not rotating, the stirring chain is in a longitudinal position. This compact shape allows the stirring chain to easily extend into small-diameter containers. When it is necessary to stir the liquid in a small-diameter container, simply activate the stirring rod to rotate, and the stirring chain will unfold and begin stirring. This approach not only maintains stirring efficiency but also successfully solves the problem of traditional stirring paddles being unable to reach small-diameter containers, greatly improving the applicability and convenience of stirring operations.

[0015] The use of a circular block, a movable block, bolts, and nuts enables a convenient and safe liquid cleaning operation. When it's necessary to clean residual liquid from the stirring rod surface, the operator simply unscrews the nut to disconnect the circular block from the movable block. The operator then holds the circular block and moves it along the surface of the stirring rod. As the circular block moves, it drives the connected arc-shaped scraper to move synchronously, scraping away the liquid adhering to the stirring rod surface. This reduces liquid residue, avoids direct contact with the liquid, and significantly lowers the safety hazard of skin injury to operators from hazardous substances in the liquid.

[0016] A convenient storage mechanism is formed through the interaction of guide rods, springs, levers, and fixing blocks. When the operator needs to store the mixer motor's power cord, they simply pinch the levers with both hands, bringing the two levers closer together. During this pinching process, the levers will cause the fixing block to slide along the surface of the guide rod. As the fixing block moves, it compresses the spring, causing it to contract. When the fixing block moves to match the opening on the surface of the baffle, the operator can then pull out the baffle. After the baffle is pulled out, the internal space of the storage box is fully exposed. At this point, the operator can neatly coil the mixer motor's power cord and place it inside the storage box. After storing the power cord, the baffle is reinstalled in its original position. This design effectively solves the problem of where to put the mixer motor's power cord and how easily it gets tangled, preventing damage to the power cord due to tangling and thus affecting the normal operation of the equipment.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6 The present invention provides the following technical solution: a chain stirrer for stirring liquid in a small-mouth container, including a stirring rod 1, a mounting block 19 at the bottom end of the stirring rod 1, a stirring chain 2 connected to the surface of the mounting block 19, a docking block 20 connected to the top surface of the mounting block 19, the stirring rod 1 and the docking block 20 being welded together, a stirring motor 3 at the top end of the stirring rod 1, a mounting column 4 connected to the output shaft of the stirring motor 3, a handle 5 connected to the surface of the stirring motor 3, and the mounting column 4 being tenon-and-mortise connected to the stirring rod 1;

[0027] A circular block 6 is fixedly connected to the surface of the mounting column 4. A movable block 7 is provided at the bottom of the circular block 6. Two symmetrical bolts 8 are connected to the top of the movable block 7. Nuts 9 are threaded on the surface of the bolts 8. Screws 11 are threaded through the surface of the movable block 7. An arc-shaped scraper 10 is provided on the inner wall of the movable block 7.

[0028] In practical use, the agitator mainly consists of several key components: a stirring rod 1, a stirring chain 2, a stirring motor 3, a mounting column 4, a handle 5, a mounting block 19, and a connecting block 20. During operation, the operator uses the handle 5 to pick up the agitator. A control button on the handle 5 connects to the stirring motor 3, allowing for easy startup. Once the motor 3 is powered on, its output shaft drives the mounting column 4 to rotate. The mounting column 4 then drives the stirring rod 1 to rotate synchronously, which in turn drives the connecting block 20. The connecting block 20 then drives the mounting block 19 to rotate. Subsequently, the stirring chain 2, connected to the surface of the mounting block 19, rotates and begins stirring. Because the stirring chain 2 directly contacts the liquid and performs the stirring action, this type of agitator is called a chain agitator. The stirring chain 2 only opens while rotating to increase the stirring area, making it suitable for small-mouthed containers.

[0029] When liquid substances, such as paint, liquid solvents, and liquid preparations, become unevenly distributed due to prolonged storage, it is difficult to achieve a homogeneous state of the various material elements during use, causing numerous inconveniences in use and construction. Chain mixers, with their unique structure, can penetrate deep into small-mouthed containers to thoroughly mix liquid substances. This not only maintains mixing efficiency but also successfully solves the problem of traditional agitators being unable to reach small-diameter containers, greatly improving the applicability and convenience of mixing operations.

[0030] Furthermore, this chain agitator is not only suitable for stirring liquids in small-mouthed containers, but also meets the stirring requirements of substances needed in liquid production processes. During stirring, it can flexibly adjust the stirring force according to changes in the viscosity of the substance in the container, and the stirring force is adjusted based on the output torque of the stirring motor 3. This provides good safety protection for the equipment. Overall, the chain agitator is currently a relatively safe, practical, and efficient new type of stirring equipment on the market.

[0031] Preferably, the arc-shaped scraper 10 can be detachably and fixedly connected to the movable block 7 by screws 11. The inner arc of the arc-shaped scraper 10 fits against the outer wall of the stirring rod 1. The movable block 7 can be detachably and fixedly connected to the circular block 6 by nuts 9 and bolts 8. The outer diameter of the circular block 6 is the same as that of the movable block 7.

[0032] In practical use, the arc-shaped scraper 10 is connected to the movable block 7 via screws 11. When the arc-shaped scraper 10 becomes deformed or damaged, the operator can easily remove it from the inside of the movable block 7 by simply removing screws 11 and replacing it with a new one. It is worth noting that the inner arc of the arc-shaped scraper 10 fits tightly against the outer wall of the stirring rod 1. In this way, when the movable block 7 moves, the arc-shaped scraper 10 effectively scrapes away the liquid adhering to the surface of the stirring rod 1, significantly reducing liquid residue on the stirring rod 1. This design avoids direct contact with the liquid, greatly reducing the safety hazard of skin damage to operators caused by hazardous substances in the liquid.

[0033] The movable block 7 is connected to the circular block 6 by a nut 9 and a bolt 8, a very convenient connection method. When the movable block 7 is not in use, it can be easily fixed in place, preventing it from moving around and affecting the normal use of the stirring rod 1. In addition, the circular block 6 and the movable block 7 have the same outer diameter, a design that ensures that they are not limited by size, allowing the stirring rod 1 to be inserted into a small-mouthed container for operation.

[0034] Preferably, a storage box 12 is mounted on the surface of the stirring motor 3. A baffle plate 13 is inserted into the front end of the storage box 12. A rectangular block 14 is connected to the front end of the storage box 12. A guide rod 15 is installed inside the rectangular block 14. A spring 16 and a fixing block 17 are sleeved on the surface of the guide rod 15. A lever 18 is connected to the front end of the fixing block 17. The fixing block 17 can be elastically linked with the rectangular block 14 through the guide rod 15, the spring 16, and the lever 18. The end of the fixing block 17 near the baffle plate 13 is L-shaped, and an opening adapted to the fixing block 17 is opened through the surface of the baffle plate 13.

[0035] In practical use, due to the use of the lever 18, when the operator pinches the lever 18 with both hands and brings them close together, the lever 18 will drive the fixed block 17 to move synchronously. Subsequently, the fixed block 17 will move smoothly along the surface of the guide rod 15. During the movement, the fixed block 17 will apply pressure to the spring 16, causing it to contract and deform.

[0036] The rectangular block 14 has an opening on its surface for the movable block 18 to move. When the movable block 18 moves from one end of the opening to the other, the fixed block 17 connected to it will coincide with the opening on the surface of the cover plate 13. At this time, the operator can easily pull the cover plate 13 out of the storage box 12, so that the internal space of the storage box 12 is fully exposed.

[0037] Next, the operator can carefully coil the power cord of the mixing motor 3 neatly and place it in the storage box 12. After storing the power cord, the cover plate 13 is reinstalled in its original position. This design effectively solves the problem of where to put the power cord of the mixing motor 3 and how it is easily scattered, avoiding damage to the power cord due to tangling, and thus ensuring that the equipment can be used normally.

[0038] Working principle: After thoroughly stirring the liquid inside the small-mouthed container and removing the chain stirrer, it must first be properly secured. Then, the operator simply needs to unscrew nut 9 to disconnect the connection between the circular block 6 and the movable block 7. Next, the operator holds the circular block 6 and moves it smoothly along the surface of the stirring rod 1. During the movement of the circular block 6, the connected arc-shaped scraper 10 moves synchronously, scraping away the liquid adhering to the surface of the stirring rod 1. This design effectively reduces liquid residue and avoids direct contact with the liquid, thus greatly reducing the safety hazard of skin injury to the operator due to hazardous substances in the liquid.

[0039] When the operator needs to store the power cord of the mixing motor 3, the operation is equally simple. Simply pinch the lever 18 with both hands, bringing the two levers 18 closer together. During this pinching process, the lever 18 will cause the fixing block 17 to slide along the surface of the guide rod 15. As the fixing block 17 moves, it compresses the spring 16, causing the spring 16 to contract. When the fixing block 17 moves to match the opening on the surface of the baffle 13, the operator can easily pull out the baffle 13. After the baffle 13 is pulled out, the internal space of the storage box 12 is fully exposed. At this time, the operator can carefully coil the power cord of the mixing motor 3 neatly and place it in the storage box 12. After completing the power cord storage, the baffle 13 is reinstalled in its original position. This design effectively solves the problem of where to put the power cord of the mixing motor 3 and how easily it becomes tangled, preventing damage to the power cord due to tangling and ensuring the normal operation of the equipment.
