Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, and more specifically, to an anti-sedimentation mixing tank. Background Technology

[0002] A mixing tank is an industrial device used for mixing or stirring liquids, slurries, and other materials. It typically consists of a tank body, a stirring device, and a drive motor, and is widely used in industries such as chemical, food, and pharmaceutical. However, some existing mixing tanks tend to have solid particles settle at the bottom after being added. This sedimentation significantly reduces the dissolution rate of the solids, easily leading to uneven mixing and affecting the normal operation of the mixing process.

[0003] To solve the above problems, a search revealed CN219232064U, which discloses a stirring tank for preventing sedimentation. The specification states that: "In this invention, solid particles fall onto the mesh partition, thereby preventing fixed particles from falling to the bottom of the tank. Then, the rotating shaft drives the rotating rod to rotate, which in turn drives the stirring ball to rotate, stirring and mixing the material at the bottom of the tank, thereby making the material evenly mixed."

[0004] However, in practical applications, this mixing tank still has certain limitations. For example, although the mesh partition design can effectively prevent solid materials from settling, when processing some poorly soluble materials (such as soaking Chinese medicinal herbs), because the mesh partition is fixed in the middle of the mixing device and is inconvenient to disassemble, the solid materials remaining on the mesh partition after the liquid is discharged are difficult to clean quickly, thus reducing the ease of operation and efficiency of the equipment. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an anti-sedimentation mixing tank to solve the problem that some mixing tanks in the prior art use mesh partitions to prevent sedimentation, but difficult-to-dissolve materials are easy to remain, and the mesh partitions are inconvenient to disassemble, resulting in cleaning difficulties and affecting the convenience of use.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an anti-sedimentation stirring tank, comprising...

[0007] A mixing tank body, the bottom of which is provided with a base, a mixing motor is fixedly installed on the upper surface of the middle part of the mixing tank body, a rotating rod is fixedly sleeved on the output end of the mixing motor, a number of mixing blades are fixedly installed on the outer surface of the rotating rod, and four U-shaped scrapers are fixedly installed on the outer surface of the rotating rod.

[0008] An anti-sinking mechanism includes a frame. The outer surface of the frame is fixedly installed on the inner surface of the middle part of the mixing tank. A central column is fixedly installed in the middle of the frame. The inner surface of the middle part of the central column is rotatably sleeved with the outer surface of the rotating rod. Several electric telescopic rods are fixedly installed on the inner surface of the central column. A lifting sleeve is fixedly installed at the top of the electric telescopic rod. The inner surface of the lifting sleeve is slidably installed on the outer surface of the middle part of the frame and the outer surface of the central column. Four fan-shaped mesh partitions are slidably installed on the inner surface of the frame. The four fan-shaped mesh partitions are arranged around the central column, and the upper surface of the end near the central column is fixedly installed on the lower surface of the lifting sleeve.

[0009] The mixing tank has a feed inlet fixedly fitted to the top and a discharge outlet opened at the bottom. A connecting pipe is fixedly fitted to the inner surface of the discharge outlet. The four U-shaped scrapers are symmetrically arranged vertically, and their far-away sides are fixedly installed to the outer surfaces of the top and bottom ends of the rotating rod, respectively.

[0010] The bottom end of the connecting pipe is fixedly fitted with a slurry removal mechanism, and a liquid outlet pipe is fixedly fitted to the outer surface of the slurry removal mechanism near one end of the connecting pipe. A filter plate is installed inside the top end of the liquid outlet pipe, and a control valve is installed in the middle of both the connecting pipe and the liquid outlet pipe.

[0011] The impurity removal mechanism includes a conveying pipe. The inner surface of the side wall of one end of the conveying pipe is fixedly sleeved with the bottom end of the connecting pipe, and the outer surface of the other end is fixedly installed with the inner surface of the base. The inner surface of the side wall of the end of the conveying pipe near the connecting pipe is fixedly sleeved with the top end of the liquid outlet pipe, and a discharge pipe is fixedly installed at the end away from the connecting pipe. A conveying motor is fixedly installed on the side of the conveying pipe, and an auger is fixedly sleeved at the output end of the conveying motor. The outer surface of the auger is rotatably installed with the inner surface of the conveying pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In the above scheme, by setting up structures such as U-shaped scrapers and anti-sinking mechanisms, the U-shaped scrapers installed on the surface of the rotating rod are first reset by the stirring motor, so that their position is aligned with the horizontal frame plate of the frame. Then, the electric telescopic rod inside the central column is retracted, pulling the lifting sleeve connected to its top end to move downward and slide along the outer surface of the middle of the frame and the outer surface of the central column. The four fan-shaped mesh partitions connected to the bottom end of the lifting sleeve move downward and detach from the inside of the frame. Then, the U-shaped scrapers that are attached to the upper surface of the fan-shaped mesh partitions rotate to scrape off the solid material on the surface of the fan-shaped mesh partitions along the gaps between them. This realizes the operation of cleaning the blocked solid material from the surface of the fan-shaped mesh partitions, so that the material can fall to the bottom of the mixing tank and be further cleaned by structures such as connecting pipes and impurity removal mechanisms, thereby improving the convenience of cleaning.

[0014] In the above scheme, by setting up a debris removal mechanism and other structures, after the liquid is discharged, the solid material cleaned to the bottom of the mixing tank falls into the inside of the conveying pipe along the connecting pipe. The conveying motor drives the auger connected to its output end to rotate. As the auger rotates along the inner wall of the conveying pipe, it will transport the solid material towards the discharge pipe until it is discharged from the discharge pipe. Furthermore, the liquid that is still present in the solid material will flow back to the liquid outlet pipe through the mesh of the auger under the inclination of the conveying pipe and other structures, thus avoiding material waste. In this way, the debris removal mechanism and other structures are used to discharge the solid material and avoid blockage. Attached Figure Description

[0021] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0022] As attached Figure 1 To be continued Figure 4 An embodiment of this utility model provides an anti-sedimentation stirring tank, including...

[0023] The mixing tank 1 has a base 2 at its bottom. A stirring motor 4 is fixedly installed on the upper surface of the middle part of the mixing tank 1. A rotating rod 5 is fixedly connected to the output end of the stirring motor 4. Several stirring blades 6 are fixedly installed on the outer surface of the rotating rod 5. Four U-shaped scrapers 7 are fixedly installed on the outer surface of the rotating rod 5.

[0024] The anti-sinking mechanism 8 includes a frame 80. The outer surface of the frame 80 is fixedly installed on the inner surface of the middle part of the mixing tank 1. A central column 81 is fixedly installed in the middle part of the frame 80. The inner surface of the middle part of the central column 81 is rotatably sleeved with the outer surface of the rotating rod 5. Several electric telescopic rods 83 are fixedly installed on the inner surface of the central column 81. A lifting sleeve 82 is fixedly installed at the top of the electric telescopic rod 83. The inner surface of the lifting sleeve 82 is slidably installed with the outer surface of the middle part of the frame 80 and the outer surface of the central column 81. Four fan-shaped mesh partitions 84 are slidably installed on the inner surface of the frame 80. The four fan-shaped mesh partitions 84 are arranged around the central column 81, and the upper surface of the end near the central column 81 is fixedly installed with the lower surface of the lifting sleeve 82.

[0025] By setting a fan-shaped mesh partition 84, the upper surface of the end of the fan-shaped mesh partition 84 is welded to the bottom end of the lifting sleeve 82 to maintain the connection strength. The frame of the mesh covering the fan-shaped mesh partition 84 can be made of memory material, so that even if the weight of the material causes bending, it can be reset after the material is cleaned up, maintaining its overlap with the frame 80.

[0026] The mixing tank 1 has a feed inlet 3 fixedly fitted to the top, and a discharge outlet 9 opened at the bottom. A connecting pipe 10 is fixedly fitted to the inner surface of the discharge outlet 9. Four U-shaped scrapers 7 are symmetrically arranged vertically, and their mutually distant side ends are fixedly installed to the outer surfaces of the top and bottom ends of the rotating rod 5, respectively.

[0027] Among them, the bottom end of the connecting pipe 10 is fixedly sleeved with a sludge removal mechanism 11, and the outer surface of the sludge removal mechanism 11 near the end of the connecting pipe 10 is fixedly sleeved with a liquid outlet pipe 14. The top end of the liquid outlet pipe 14 is provided with a filter plate 12, and the middle part of the connecting pipe 10 and the liquid outlet pipe 14 are both provided with a control valve 13.

[0028] By setting up a connecting pipe 10, a control valve 13, and other structures, when liquid material is discharged, the control valve 13 in the middle of the outlet pipe 14 and the middle of the connecting pipe 10 can be opened sequentially, so that the liquid flows into the interior of the conveying pipe 110 along the connecting pipe 10. Under the action of the inclined conveying pipe 110, the liquid will gather on the inner wall near the end of the outlet pipe 14, and flow into the outlet pipe 14 from the mesh auger 112 and the filter plate 12 set in the inner cavity at the top of the outlet pipe 14, thus completing the discharge of the liquid.

[0029] The impurity removal mechanism 11 includes a conveying pipe 110. The inner surface of the side wall of one end of the conveying pipe 110 is fixedly sleeved with the bottom end of the connecting pipe 10, and the outer surface of the other end is fixedly installed with the inner surface of the base 2. The inner surface of the side wall of the end of the conveying pipe 110 near the connecting pipe 10 is fixedly sleeved with the top end of the liquid outlet pipe 14, and the end away from the connecting pipe 10 is fixedly installed with a discharge pipe 113. A conveying motor 111 is fixedly installed on the side of the conveying pipe 110. An auger 112 is fixedly sleeved at the output end of the conveying motor 111. The outer surface of the auger 112 is rotatably installed with the inner surface of the conveying pipe 110.

[0030] The working process of this utility model is as follows:

[0031] In the actual production process, both solid and liquid materials are fed into the mixing tank 1 through the feed inlet 3 at the top of the mixing tank 1. The solid materials are blocked by the anti-sinking mechanism 8 set in the middle of the mixing tank 1 to prevent them from settling at the bottom of the mixing tank 1. At the same time, the rotating rod 5 connected to the output end of the stirring motor 4 drives the rotating rod 5 to rotate inside the mixing tank 1. The stirring blades 6, U-shaped scrapers 7 and other structures installed on it will rotate synchronously. The stirring blades 6 are used to stir the materials inside the mixing tank 1, and the U-shaped scrapers 7 are used to scrape the inner surface of the side wall of the mixing tank 1.

[0032] After stirring, the liquid can be discharged first using the connecting pipe 10 and other structures. Then, the anti-sinking mechanism 8 can be adjusted to discharge and clean the undissolved solid material. The specific operation is as follows: First, the U-shaped scraper 7 installed on the surface of the rotating rod 5 is reset by the stirring motor 4 so that its position is aligned with the horizontal frame plate of the frame 80. Then, the electric telescopic rod 83 inside the central column 81 is retracted, pulling the lifting sleeve 82 connected to its top end to move downward and slide along the outer surface of the middle part of the frame 80 and the outer surface of the central column 81. The four fan-shaped mesh partitions 84 connected to the bottom end of the lifting sleeve 82 move downward and separate from the inside of the frame 80. At this time, the plane on the upper surface of the fan-shaped mesh partition 84 is the same horizontal plane as the plane on the lower surface of the top of the U-shaped scraper 7 installed at the bottom of the mixing tank 1. Therefore, the stirring motor 4, rotating rod 5 and other structures are controlled to make the U-shaped scraper 7 rotate, thereby scraping off the solid material on the surface of the fan-shaped mesh partition 84 along the gaps between them, thus realizing the operation of cleaning the blocked solid material from the surface of the fan-shaped mesh partition 84.

[0033] After the liquid is discharged, the solid material that has been cleaned to the bottom of the mixing tank 1 falls into the inside of the conveying pipe 110 along the connecting pipe 10. The conveying motor 111 drives the auger 112 connected to its output end to rotate. As the auger 112 rotates along the inner wall of the conveying pipe 110, it will transport the solid material towards the discharge pipe 113 until it is discharged from the discharge pipe 113. Furthermore, the liquid that is still present in the solid material will be transported by the auger 112 and, under the inclination of the conveying pipe 110 and other structures, will flow back to the liquid outlet pipe 14 through the mesh of the auger 112, thus avoiding material waste.
