Description

Technical Field

[0001] This utility model relates to the field of submersible mixer technology, specifically a submersible mixer for treating pig farm wastewater. Background Technology

[0002] Pig farming wastewater consists of pig urine, pig manure, feed residue, pigsty flushing water, and a small amount of domestic sewage generated by workers. The main characteristics of this wastewater are high organic matter concentration, high suspended solids, dark color, and a large number of bacteria. Submersible mixers, also known as submersible propellers, are required for treatment. They are suitable for use in wastewater treatment plant processes to propel and agitate wastewater containing suspended solids, thin sludge, and industrial process liquids, creating water flow, enhancing agitation, and preventing sludge sedimentation.

[0003] In existing submersible mixers, a fixed guide rod is installed inside the tank during installation, so that the guide structure at the rear end of the submersible mixer is connected to the guide rod in a lifting manner. Then, a lifting device is installed above the submersible mixer to control the lifting of the submersible mixer.

[0004] However, when the submersible mixer operates at the required height, the resulting vibration is significant, which can affect and damage the transmission structure of the mixer, and also results in low operational stability. Therefore, we propose a submersible mixer for pig farm wastewater treatment. Utility Model Content

[0005] The purpose of this utility model is to provide a submersible mixer for treating pig wastewater. By setting a locking plate with rubber blocks on the inner side of the guide frame, which can be abutted against the surface of the guide rod by a spring, and combined with the repulsive force between the electromagnets, the guide frame structure can be locked and stabilized, thereby reducing vibration during operation, ensuring the stability of the machine body, and reducing the impact on the transmission structure such as the guide roller, thus providing protection and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a submersible mixer for treating pig wastewater, comprising a body and a guide frame, wherein the guide frame is fixed to the back surface of the body, and the upper and lower parts of the guide frame are open to the outside; a first guide roller and a second guide roller are rotatably mounted on two sets of opposing surfaces inside the guide frame; locking plates are provided on the upper and lower sides of both sides of the guide frame; rubber blocks are fixed to the outer surface of the locking plates; connecting rods are fixed on both sides of the locking plates facing the guide frame; the connecting rods can slide through into a shield fixed to the outer surface of the guide frame; a slider that can slide inside the shield is fixed to the end of the connecting rod; a spring is placed between the slider and the shield; a first electromagnet is embedded inside the slider; an inner post placed in the spring is fixed inside the shield; a second electromagnet is embedded inside the inner post on the side of the inner post facing the slider.

[0007] By adopting the above technical solution, the guide frame is fitted onto the outer ring of the guide rod, so that the machine body is guided when it is raised and lowered. Before the machine body is started, the repulsive force of the electromagnet and the resisting action of the spring are used to press the rubber block on the surface of the locking plate against the outer surface of the guide rod to lock the guide frame and the machine body, thus ensuring stable operation when the machine body is started.

[0008] Optionally, a lifting ring is fixed to the surface of the machine body, and the lifting ring is located above the machine body on the side away from the guide frame.

[0009] By adopting the above technical solution, the lifting equipment is connected to the top of the machine body through lifting rings.

[0010] Optionally, the guide frame surface at the connecting rod is provided with a perforation, through which the connecting rod passes through the guide frame.

[0011] Optionally, multiple first and second guide rollers are provided, and the first and second guide rollers are evenly installed inside the guide frame and close to the inner wall surface of the guide frame.

[0012] By adopting the above technical solution, multiple first guide rollers and second guide rollers achieve stable guidance during the lifting and lowering of the machine body.

[0013] Optionally, a flow guide is fixed to the outer ring of the fan blades of the machine body, and the flow guide is fixed to the outer shell of the machine body.

[0014] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0015] 1. The technical solution of this application provides a locking plate with rubber blocks on the inner side of the guide frame. The plate can be pressed against the surface of the guide rod by a spring. Combined with the repulsive force between the electromagnets, it plays a good role in locking and stabilizing the guide frame structure, thereby reducing vibration during operation, ensuring the stability of the machine body, and reducing the impact on the transmission structure such as the guide roller, thus playing a protective role.

[0016] 2. The technical solution of this application sets the first electromagnet and the second electromagnet in the slider and the inner column respectively, which can play the roles of adsorption and clamping when needed, thereby increasing the force of the rubber block against the surface of the guide rod.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a submersible mixer for treating pig wastewater, including a body 1 and a guide frame 2. The guide frame 2 is fixed to the back surface of the body 1. The top and bottom of the guide frame 2 are open to the outside. A lifting ring 11 is fixed on the surface of the body 1. The lifting ring 11 is located above the body 1 away from the left side. The lifting structure is connected to the top of the body 1 through the lifting ring 11, which can realize the purpose of lifting and lowering the height of the body 1.

[0024] Inside the guide frame 2, two sets of opposing surfaces are rotatably equipped with a first guide roller 21 and a second guide roller 22. During installation and use, the guide frame 2 is fitted over the outer ring of the guide rod from above, and then the first guide roller 21 and the second guide roller support abut against the outer surface of the guide rod. When the machine body 1 is lifted to a certain height, the first guide roller 21 and the second guide roller 22 roll against the outer surface of the guide rod installed on the inner wall of the pool, which plays a stabilizing role during lifting. Multiple first guide rollers 21 and second guide rollers 22 are provided. The first guide rollers 21 and the second guide rollers 22 are evenly installed inside the guide frame 2 and close to the inner wall surface of the guide frame 2. The multiple first guide rollers 21 and the second guide rollers 22 provide better guiding stability.

[0025] Fan blades are installed on the output shaft of the machine body 1. When started, the fan blades are rotated to agitate the sewage. A flow guide is fixed on the outer ring of the fan blades of the machine body 1. The flow guide is fixed on the outer shell of the machine body 1. After the flow guide is installed, the fluid velocity is continuously increased along the axial direction of the submersible mixer. The axial outward diffusion of the fluid is relatively small, which improves the efficiency of the mixer, reduces equipment vibration, and ensures stable operation.

[0026] Locking plates 3 are provided on the upper and lower sides of both sides of the guide frame 2. Rubber blocks 31 are fixed to the outer surface of the locking plates 3. Connecting rods 32 are fixed on both sides of the locking plates 3 facing the guide frame 2. The surface of the guide frame 2 at the connecting rods 32 is provided with perforations. The connecting rods 32 can slide through the perforations into the shielding cover 4 fixed on the outer surface of the guide frame 2. The end of the connecting rods 32 is fixed with a slider 33 that can slide inside the shielding cover 4. A spring 42 is placed between the slider 33 and the shielding cover 4. Under normal circumstances, the spring 42 will push the slider 33, so that the rubber blocks 31 on the surface of the locking plates 3 will contact the surface of the guide rods.

[0027] To prevent the rubber block 31 from contacting the guide rod surface and hindering the smooth lifting and lowering of the guide frame 2 during height adjustment, a first electromagnet 331 is embedded inside the slider 33, while an inner column 41 placed in the spring 42 is fixed inside the shield 4. A second electromagnet 411 is embedded inside the inner column 41 near the slider 33. Before height adjustment, the two electromagnets are made to have opposite magnetic poles and attract each other, which can compress the spring 42 and, through the connecting rod 32, cause the rubber block 31 on the surface of the locking plate 3 to no longer contact the guide rod surface. This releases the lock, allowing the machine body 1 to be lifted and lowered by the lifting equipment. During operation, the first electromagnet 331 and the second electromagnet 411 are made to have the same magnetic poles, which can generate a repulsive force. Combined with the abutting force of the spring 42, the slider 33 is pushed outward, causing the rubber block 31 on the surface of the locking plate 3 to press against the outer surface of the guide rod, thus achieving a stable locking effect on the guide frame 2 and the machine body 1.

[0028] In use, the guide frame 2 is fitted over the guide rod installed on the inner wall of the pool. The first guide roller 21 and the second guide roller 22 respectively abut against the outer surface of the guide rod. After installation, the locking plate 3, under the action of the spring 42, will also cause its rubber block 31 to abut against the outer surface of the guide rod. Then, the lifting structure is connected to the lifting ring 11 above the machine body 1. The machine body 1, the first electromagnet 331, and the second electromagnet 411 are all connected to the control device and the control device is energized. Before adjusting the height of the machine body 1, the first electromagnet 331 and the second electromagnet 411 are energized. Since they have opposite magnetic poles, they attract each other, causing the slider 33 to slide towards the inner column 41. The locking plate 3 is moved to the inner wall of the guide frame 2 by the connecting rod 32, so that the rubber block 31 no longer abuts against the surface of the guide rod and is locked. Then, the lifting structure can be used to raise and lower the height of the machine body 1 inside the pool, and adjust the machine body 1 to the required operating height. Before the machine body 1 is started, the first electromagnet 331 and the second electromagnet 411 are made to have the same magnetic poles, which can generate a repulsive force. Combined with the abutting force of the spring 42, the slider 33 is pushed outward, so that the rubber block 31 on the surface of the locking plate 3 is pressed against the outer surface of the guide rod, so as to achieve a stable locking effect on the guide frame 2 and the machine body 1. After that, when the machine body 1 is started to work and stir, it has a sufficient stabilizing effect.
