Description

Technical Field

[0001] This application relates to the technical field of mixing devices, and in particular to a stirring and mixing device for improving the mixing degree. Background Art

[0002] A mixing device is a device that fully mixes two or more materials through physical stirring.

[0003] The existing utility model patent with the publication number CN220496124U discloses an enzyme fertilizer mixing and stirring device, including a support plate. A mounting cylinder is fixedly arranged in the middle at the bottom of the support plate. A rotating shaft is rotatably arranged inside the mounting cylinder. A driving motor is fixedly arranged above the support plate and is in transmission connection with the rotating shaft. Stirring rod assemblies are uniformly arranged on the rotating shaft. A clamping plate is in threaded connection with the outer side of the mounting cylinder. A control box is arranged on the support plate. The control box has a control module and a contactor connected to the output end of the control module. The control module controls the main circuit of the driving motor to be switched on or off through the contactor.

[0004] Regarding the above related technologies, the inventor believes that when mixing feed raw materials, oils and solid particles need to be put in. However, relying only on the rotation of the blades on the horizontal plane, it is still difficult to fully mix the oil floating on the surface of the materials and the solid particles deposited at the bottom of the materials, which needs to be improved. Utility Model Content

[0005] This application provides a stirring and mixing device for improving the mixing degree, which will enable the oil floating on the surface of the materials and the solid particles deposited at the bottom of the materials to be fully mixed with the materials, improving the uniformity after mixing.

[0006] A stirring and mixing device for improving the mixing degree provided by this application adopts the following technical solutions:

[0007] The stirring and mixing device for improving the mixing degree includes a tank body. The tank body is provided with a motor and a stirring shaft driven by the motor to rotate. Upper spiral blades and lower spiral blades are fixed on the outer wall of the stirring shaft. The spiral directions of the lower spiral blades and the upper spiral blades are opposite. The bottom of the lower spiral blades is in sliding contact with the inner bottom wall of the tank body. A connecting rod is fixed on the outer wall of the stirring shaft. The outer end of the connecting rod is fixed with a bent plate. The bent plate is in sliding contact with the edge of the inner bottom wall of the tank body and the bottom of the inner side wall of the tank body at the same time.

[0008] By adopting the above technical solution, the materials to be mixed are poured into the tank body, and the top of the upper spiral blade needs to be higher than the liquid level of the materials in the tank body. Then, the motor is started to drive the stirring shaft to rotate, and the upper spiral blade and the lower spiral blade rotate. Through the spiral feeding action of the upper spiral blade, the materials located in the upper part of the tank body move downward, and the oil substances on the top surface of the materials can be pushed deep into the tank body, so that the oil is fully mixed with other materials. Through the spiral feeding action of the lower spiral blade, the solid particles located at the bottom of the tank body move upward, so that the solid particles are fully mixed with other materials, thereby achieving the purpose of fully mixing all the materials and improving the uniformity of the mixture after mixing. The edge of the inner bottom wall of the tank body is a part that cannot be reached by the lower spiral blade. By scraping this position with the bent plate, the materials at this position can be scraped up, so as to participate in the rolling flow of the materials in the tank body and improve the mixing uniformity.

[0009] Optionally, at least two bent plates are symmetrically arranged along the circumferential direction of the tank body.

[0010] By adopting the above technical solution, at least two bent plates can balance the weights on both sides of the stirring shaft, improve the rotation stability, and improve the stirring effect.

[0011] Optionally, a ring one is fixed at the bottom of the upper spiral blade, a ring two is fixed at the top of the lower spiral blade, and a plurality of stirring blades are fixed between the ring one and the ring two.

[0012] By adopting the above technical solution, when the stirring blades rotate, they play a role of throwing the materials inside outward, and the rotation of the stirring blades makes the materials at this position move more smoothly and quickly along the radial direction of the stirring shaft.

[0013] Optionally, a plurality of through grooves are formed at the top of the ring one, and the through grooves correspond to the positions between adjacent stirring blades.

[0014] By adopting the above technical solution, the function of the through grooves is to make the top of the space between the stirring blades open. When the tank body needs to be cleaned after use, it is rinsed with a water pipe from the top of the tank body, and the water can conveniently clean the space between the ring one and the ring two through the through grooves, so as to facilitate the cleaning of both sides of the stirring blades.

[0015] Optionally, a support ring is fixed at the top of the upper spiral blade, a plug rod is fixed on the support ring, a placement ring is sleeved outside the plug rod, and a secondary spiral blade is fixed on the placement ring. The rotation direction of the secondary spiral blade is the same as that of the upper spiral blade.

[0016] By adopting the above technical solution, when pouring materials into the tank body, it is possible that there is too much material above the top of the upper spiral blade, resulting in poor mixing effect of the oil substances on the top surface of the material by the upper spiral blade. At this time, the placement ring can be placed on the support ring, and the insertion rod is passed through the placement ring. When the auxiliary spiral blade rotates with the upper spiral blade, it functions the same as the upper spiral blade. Since the upper end of the auxiliary spiral blade is ensured to be higher than the liquid level of the material, it can play a corresponding mixing role for the oil substances on the top surface of the material.

[0017] Optionally, an external thread is provided on the outer wall of the insertion rod, and a pull rod is threadedly connected to the outer wall of the insertion rod.

[0018] By adopting the above technical solution, through the threaded connection between the pull rod and the external thread on the outer wall of the insertion rod, the placement ring is fixed after tightening the pull rod, ensuring the stability during the rotation of the auxiliary spiral blade.

[0019] Optionally, a threaded hole is provided on the placement ring, and a threaded section adapted to the threaded hole is provided on the outer wall of the pull rod.

[0020] By adopting the above technical solution, through the threaded connection between the pull rod and the threaded hole, it is convenient to move the placement ring and the auxiliary spiral blade through the pull rod, and the pull rod can also be separated from the placement ring.

[0021] Optionally, a pull ring is fixed at the top end of the pull rod.

[0022] By adopting the above technical solution, the pull ring is convenient for human hands to hold and is convenient for operating the pull rod.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Through the spiral feeding action, the upper spiral blade moves the materials located in the upper part of the tank body downward, and can push the oil substances on the top surface of the materials deep into the materials, so that the oil is fully mixed with other materials;

[0025] 2. Through the spiral feeding action, the lower spiral blade moves the solid particles located at the bottom of the tank body upward, so that the solid particles are fully mixed with other materials;

[0026] 3. Combining with the scraping action of the curved plate on the edge of the inner bottom wall of the tank body, the purpose of fully mixing all materials is achieved, and the uniformity after mixing is improved. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0033] The following further describes the present application in detail with reference to the accompanying drawings. Embodiment 1:

[0034] Referring to Figure 1 , this embodiment discloses a stirring and mixing device for improving the mixing degree, including a tank body 1. The tank body 1 is a cylindrical container with an open top. The tank body 1 is provided with a motor 11 and a stirring shaft 2 driven by the motor 11 to rotate. The motor 11 is fixed to the outer bottom wall of the tank body 1, and the stirring shaft 2 is located inside the tank body 1. The output shaft of the motor 11 is fixedly connected to the lower end of the stirring shaft 2. A discharge pipe 12 is fixed to the bottom of the outer side wall of the tank body 1. A valve is provided on the discharge pipe 12, and the discharge pipe 12 is used to discharge the mixed material.

[0035] The outer wall of the stirring shaft 2 is fixed with an upper spiral blade 3 and a lower spiral blade 4. The lower spiral blade 4 is located below the upper spiral blade 3. The spiral directions of the lower spiral blade 4 and the upper spiral blade 3 are opposite. The bottom of the lower spiral blade 4 is in sliding contact with the inner bottom wall of the tank body 1, and the top of the upper spiral blade 3 needs to be higher than the liquid level of the material inside the tank body 1. When the motor 11 drives the stirring shaft 2 to rotate, its rotation direction is set as follows: the upper spiral blade 3 makes the material located in the upper part of the tank body 1 move downward through the spiral feeding effect; the lower spiral blade 4 makes the material located in the lower part of the tank body 1 move upward through the spiral feeding effect; the material reaching the middle part of the tank body 1, that is, the material between the upper spiral blade 3 and the lower spiral blade 4, moves radially outward along the stirring shaft 2.

[0036] Referring to Figure 1 and Figure 2, a first ring 31 is fixed to the bottom of the upper helical blade 3, a second ring 41 is fixed to the top of the lower helical blade 4, and a plurality of stirring blades 5 are fixed between the first ring 31 and the second ring 41. The stirring blades 5 are arranged vertically and are circumferentially symmetrically distributed about the axis of the stirring shaft 2. A plurality of through grooves 32 are formed in the top of the first ring 31, and the through grooves 32 correspond to the positions between adjacent stirring blades 5. The stirring blades 5 can rotate together with the stirring shaft 2. When the stirring blades 5 rotate, they play a role of throwing the materials inside outwards. The principle is similar to that of the impeller of a centrifugal pump. When the stirring blades 5 rotate, the materials at this position move more smoothly and quickly along the radial direction of the stirring shaft 2, so as to accelerate the tumbling of the materials in the tank body 1 and improve the mixing efficiency. The function of the through grooves 32 is to make the top of the space between the stirring blades 5 open. When the tank body 1 needs to be cleaned after use, it is rinsed with a water pipe from the top of the tank body 1, and the water can conveniently clean the space between the first ring 31 and the second ring 41 through the through grooves 32, so as to facilitate the cleaning of both sides of the stirring blades 5.

[0037] Referring to Figure 1 , a connecting rod 21 is fixed to the outer wall of the stirring shaft 2, and a bent plate 22 is fixed to the outer end of the connecting rod 21. The bent plate 22 is in sliding contact with the edge of the inner bottom wall of the tank body 1 and the bottom of the inner side wall of the tank body 1 at the same time. At least two bent plates 22 are symmetrically arranged along the circumferential direction of the tank body 1. The edge of the inner bottom wall of the tank body 1 is a part that the lower helical blade 4 cannot reach. By scraping this position with the bent plate 22, the materials at this position can be scraped up, so as to participate in the tumbling flow of the materials in the tank body 1 and improve the mixing uniformity.

[0038] The implementation principle of a stirring and mixing device for improving the mixing degree according to an embodiment of the present application is as follows: Pour the materials to be mixed into the tank body 1, and the top of the upper helical blade 3 needs to be higher than the liquid level of the materials in the tank body 1. Then start the motor 11 to drive the stirring shaft 2 to rotate, and the upper helical blade 3, the lower helical blade 4, and the stirring blades 5 all rotate.

[0039] Through the spiral feeding action, the upper helical blade 3 makes the materials in the upper part of the tank body 1 move downward, and can push the oil substances on the top surface of the materials into the deep part, so that the oil is fully mixed with other materials. Through the spiral feeding action, the lower helical blade 4 makes the solid particles located at the bottom of the tank body 1 move upward, so that the solid particles are fully mixed with other materials, so as to achieve the purpose of fully mixing all the materials and improve the uniformity after mixing. Embodiment Two:

[0040] Referring to Figure 3 and Figure 4, A stirring and mixing device for improving the mixing degree. The difference between the second embodiment and the first embodiment is as follows: A support ring 33 is fixed to the top of the upper spiral blade 3. An insertion rod 34 is fixed to the support ring 33. Two insertion rods 34 are symmetrically arranged along the circumferential direction of the support ring 33. A placement ring 6 is sleeved outside the insertion rod 34. A secondary spiral blade 61 is fixed to the placement ring 6. The spiral direction of the secondary spiral blade 61 is the same as that of the upper spiral blade 3.

[0041] Referring to Figure 4 and Figure 5 , external threads are provided on the outer wall of the insertion rod 34. A pull rod 7 is threadedly connected to the outer wall of the insertion rod 34. A pull ring 71 is fixed to the top end of the pull rod 7. The pull ring 71 is convenient for manual holding operation. Thread holes 62 are provided on the placement ring 6. Two thread holes 62 are symmetrically arranged along the circumferential direction of the placement ring 6. A threaded section 72 adapted to the thread hole 62 is provided on the outer wall of the pull rod 7, that is, internal and external threads are provided on both walls at the bottom end of the pull rod 7. The internal thread of the pull rod 7 is used for threaded connection with the insertion rod 34, and the threaded section 72 on the outer part of the pull rod 7 is used for threaded connection with the thread hole 62.

[0042] The implementation principle of the second embodiment is: The secondary spiral blade 61 is an item that can be selectively used and belongs to an accessory. By default, the pull rod 7 is threadedly connected to the thread hole 62.

[0043] When pouring materials into the tank body 1, it may happen that the materials are too much and higher than the top of the upper spiral blade 3, resulting in poor mixing effect of the oil substances on the top surface of the materials by the upper spiral blade 3. At this time, the pull ring 71 can be held, the placement ring 6 can be placed on the support ring 33, and the insertion rod 34 can be passed through the placement ring 6. Then, the pull rod 7 is rotated to disconnect the lower end of the pull rod 7 from the threaded connection with the thread hole 62. Then, the lower end of the pull rod 7 is sleeved outside the insertion rod 34, and the pull rod 7 is rotated to threadedly connect it with the external thread of the insertion rod 34. After tightening the pull rod 7, the fixation of the placement ring 6 is completed.

[0044] When the secondary spiral blade 61 rotates with the upper spiral blade 3, it functions the same as the upper spiral blade 3. Since the upper end of the secondary spiral blade 61 is ensured to be higher than the liquid level of the materials, it can play a corresponding mixing role for the oil substances on the top surface of the materials.

[0045] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
