Description

Technical Field

[0001] This utility model belongs to the field of stirring blade technology, specifically relating to a powerful stirring blade for viscous liquids. Background Technology

[0002] A stirring blade is a mechanical device used for mixing, stirring, or homogenizing materials, and is widely used in industries such as chemical, food, and pharmaceutical.

[0003] The stirring blade is divided into a head and a tail. When stirring a very viscous liquid, the head needs to contact the liquid first to reduce resistance on the blade. If the stirring blade rotates in the opposite direction, the viscous liquid will exert greater resistance during rotation, easily causing the blade to twist or bend. Therefore, this application proposes a powerful stirring blade for viscous liquids, where the rotation direction of the stirring blade can be manually determined by the illumination of a signal light, allowing for human intervention to prevent the blade from rotating in the opposite direction for an extended period. Utility Model Content

[0004] The purpose of this invention is to provide a powerful stirring blade for viscous liquids to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a powerful stirring blade for viscous liquids, comprising a sleeve and blades, wherein the blades include a head and a tail, and multiple blades are arranged in a circumferential array on the outer wall of the sleeve, and the head is provided with an angled structure.

[0006] The blade includes a head and a tail, with the head having an angled structure;

[0007] The sleeve is equipped with a rotation direction detection unit, which includes a sector block located inside the detection box. The sector block can move along the inner wall of the detection box. A conductive block is provided inside the sector block. The detection box is provided with a first left power terminal, a second left power terminal, a first right power terminal, and a second right power terminal.

[0008] The first left and first right electrical terminals are connected to a power source, the second left electrical terminal is connected to the left signal light, and the second right electrical terminal is connected to the right signal light. When the sleeve and blade rotate in the direction that the tail of a single blade faces its inner head, the conductive block connects the first left and second left electrical terminals, and the left signal light connected to the second left electrical terminal is energized and lit. When the sleeve and blade rotate in the direction that the head faces the tail, the conductive block connects the first right and second right electrical terminals, and the right signal light connected to the second right electrical terminal is lit.

[0009] Preferably, a groove is provided inside the sleeve at the position corresponding to the blade, and the groove cooperates with the protrusion in the blade.

[0010] Preferably, the sleeve has a keyway inside that mates with the key.

[0011] Preferably, a rib is provided at the tail of the blade, one end of the rib is connected to an arc plate, and the arc groove in the arc plate fits against the outer wall of the sleeve. The tail of the blade is equipped with a rib, and the rib is connected to the arc plate, which fits against the outer wall of the sleeve.

[0012] Preferably, the blade has an outward push structure at both the top and bottom. The outward push structure includes multiple smoothly connected arc segments, and the height of the outward push structure on the side closer to the sleeve is higher than the height on the side farther from the sleeve.

[0013] Preferably, the conductive block and the sector block are connected by an insulating sleeve, and the entire detection box is made of insulating rubber material.

[0014] Preferably, the left signal light is a green signal light, while the right signal light is a red signal light.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] I. This utility model is provided with a rotation direction detection unit on the sleeve. Two springs are connected to both sides of the sector block in the rotation direction detection unit. When the sleeve is stationary, the sector block is located in the middle of the entire detection box under the action of the elastic force of the two springs. When the sleeve rotates and agitates the viscous liquid, the detection box rotates with the sleeve, and the sector block is in its original position under the action of inertia. In this way, the sector block approaches the inner wall of one side of the detection box, and finally the adsorption block inside the sector block contacts the electromagnet on that side.

[0018] Both electromagnets on both sides are activated, and the sector block is attracted by the electromagnet that is closer. At this time, the conductive block closes the circuit connected to the left indicator light, that is, it closes the connection between the first left terminal and the second left terminal, allowing the left indicator light to light up. Meanwhile, the sleeve rotates in the opposite direction, the sector block moves closer to the other end of the detection box, and the right indicator light lights up. The direction of the sleeve rotation is determined based on the status of the two indicator lights, and manual intervention is used to prevent the sleeve and blade from rotating in the opposite direction for a long time.

Detailed Implementation

[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] Reference Figures 1-5 A powerful stirring blade for viscous liquids includes a sleeve 1 and blades 2. Multiple blades 2 are arranged in a circumferential array on the outer wall of the sleeve 1. A groove 101 is provided inside the sleeve 1 at the position corresponding to the blade 2. The groove 101 cooperates with the protrusion 201 in the blade 2. Before welding, the blade 2 and the sleeve 1 are connected by inserting through the groove 101 and the protrusion 201. Thus, when the blade 2 needs to be welded to the outer wall of the sleeve 1, the protrusion 201 is first inserted into the groove 101. The two are tightly fitted, which can restrict the position of the blade 2, so that the position of the blade 2 is not easy to loosen during welding.

[0027] It should be noted that the sleeve 1 has a keyway 102 inside that mates with the key;

[0028] In a further embodiment, refer to Figure 1 , Figure 2The blade 2 includes a head 202 and a tail 203. The head 202 is provided with an angled structure. When stirring viscous liquid, the contact area between the angled structure and the viscous liquid is smaller than that of the tail 203 during rotation. When rotating, the angled structure can reduce the resistance of the viscous liquid to the entire blade 2, while the tail 203 can push the viscous liquid to flow, thereby making the viscous liquid flow and mix it evenly with the viscous liquid.

[0029] Viscous liquids have poor fluidity. If it is necessary to agitate the viscous liquid, the blade 2 will be subjected to a large force during rotation. To prevent it from tilting, a rib 3 is provided at the tail 203 of the blade 2. One end of the rib 3 is connected to an arc plate 4. The arc groove in the arc plate 4 fits against the outer wall of the sleeve 1. The rib 3 is located in the area of ​​the tail 203 of the blade 2. During the rotation of the blade 2, the head 202 pushes the viscous liquid to flow first. The tail 203 of the blade 2 is equipped with the rib 3, and the rib 3 is connected to the arc plate 4. The arc plate 4 fits against the outer wall of the sleeve 1. In this way, when welding the rib 3 to the sleeve 1, the arc plate 4 can be directly welded to the position where it is connected to the sleeve 1. Welding the arc plate 4 is more convenient than welding the rib 3. It should be noted that the side of the rib 3 closer to the sleeve 1 is thicker, and the side farther away from the sleeve 1 is thinner. The whole is designed as a smooth arc shape.

[0030] It should be mentioned that the blade 2 is provided with an outward push structure at both the top and bottom. The outward push structure includes multiple smoothly connected arc segments, and the height of the outward push structure on the side closer to the sleeve 1 is higher than the height on the side farther away from the sleeve 1. In this way, when the blade 2 pushes the viscous liquid to flow, it can push the viscous liquid to move away from the sleeve 1, so that the viscous liquid has multiple flow directions, which helps to accelerate the mixing speed of the viscous liquid.

[0031] The blade 2 is equipped with a head 202 and a tail 203 for stirring viscous liquids, therefore, during its rotation, it rotates clockwise (see reference). Figure 1 To detect the rotation direction of blade 2, a rotation direction detection unit 5 is installed on sleeve 1. The rotation direction detection unit 5 includes a sector block 501. Springs are installed on both sides of the sector block 501. The sector block 501 is located inside the detection box and can move along the inner wall of the detection box. A conductive block 502 is provided inside the sector block 501. An insulating sleeve is wrapped around the connection between the conductive block 502 and the sector block 501. The entire detection box is made of insulating rubber material. The detection box is provided with a first left electrical terminal 503, a second left electrical terminal, a first right electrical terminal 504, and a second right electrical terminal.

[0032] It should be noted that the first left electrical terminal 503 and the first right electrical terminal 504 are connected to the power supply, the second left electrical terminal is connected to the left signal light 506, and the second right electrical terminal is connected to the right signal light 507. The signal lights and the power supply are connected to form a complete circuit. When the sleeve 1 and the blade 2 rotate in the direction that the tail 203 of a single blade 2 is facing its inner head 202, the conductive block 502 is connected to the first left electrical terminal 503 and the second left electrical terminal, and the left signal light 506 connected to the second left electrical terminal is in a state of flux. When the power is on, the left indicator light 506 is green. When the sleeve 1 and blade 2 rotate in the direction that the head 202 faces the tail 203, the conductive block 502 connects the first right terminal 504 and the second right terminal, and the right indicator light 507 connected to the second right terminal lights up. The right indicator light 507 is red. In this way, the rotation direction of the sleeve 1 and blade 2 can be judged by the switch of the two indicator lights. This makes it convenient to check the rotation direction of the sleeve 1 and blade 2.

[0033] The detection box is equipped with two electromagnets 505, which are located at the left and right ends of the detection box. The detection box is connected to a counterweight 6, which together with the detection box form a ring. This ensures that the gravity is roughly the same at all points when rotating, and there will be no obvious tilting.

[0034] Working principle:

[0035] The sleeve 1 is provided with multiple blades 2, which are divided into a head 202 and a tail 203. The head 202 is provided with an angled structure. The angled structure in the sleeve 1 first pushes the viscous liquid to flow, which can reduce the resistance of the viscous liquid to the blade 2, thereby reducing the resistance of the viscous liquid to the entire blade 2 during the rotation of the blade 2. The blade 2 can be used stably and for a long time.

[0036] A rotation direction detection unit 5 is provided on the sleeve 1. Two springs are connected to both sides of the sector block 501 in the rotation direction detection unit 5. When the sleeve 1 is stationary, the sector block 501 is located in the middle of the entire detection box under the action of the two spring forces. When the sleeve 1 rotates and agitates the viscous liquid, the detection box rotates with the sleeve 1, and the sector block 501 is in its original position under the action of inertia. Thus, the sector block 501 approaches the inner wall of one side of the detection box, and finally the adsorption block inside the sector block 501 contacts the electromagnet 505 on that side.

[0037] Both electromagnets 505 on both sides are turned on. The sector block 501 is attracted by the electromagnet 505 that is closer to it. At this time, the conductive block 502 closes the circuit connected to the left signal light 506, that is, closes the connection between the first left power terminal 503 and the second left power terminal, so that the left signal light 506 can light up. Meanwhile, the sleeve 1 rotates in the opposite direction, the sector block 501 moves closer to the other end of the detection box, and the right signal light 507 lights up. The direction of rotation of the sleeve 1 is determined based on the status of the two signal lights.
