Description

Technical Field

[0001] This application relates to the technical field of wastewater treatment, and in particular to a stirrer fixing device. Background Technology

[0002] In the process of treating sewage, mixing is an indispensable and important step in sewage treatment equipment. It can effectively improve sewage treatment efficiency and ensure that water quality meets standards.

[0003] Currently, the main methods for fixing mixing equipment on the market include fixed brackets and fixed clamps. Fixed brackets are usually directly installed on the wall or bottom of the sewage treatment tank to fix the mixing equipment in the required position, while fixed clamps fix the mixing equipment in the designated position through a clamping mechanism.

[0004] The two fixing methods mentioned above can ensure the stability of the equipment to a certain extent. However, when the mixing equipment needs regular maintenance or malfunctions, it needs to be removed from the sewage treatment tank for repair. This disassembly and assembly process is cumbersome and causes inconvenience for the maintenance of the mixing equipment. Utility Model Content

[0005] To facilitate the maintenance and repair of the mixer, this application provides a mixer fixing device.

[0006] This application provides a stirrer fixing device, which adopts the following technical solution:

[0007] A stirrer fixing device, comprising:

[0008] Mounting frame, which is fixedly installed on the wall of the sewage tank that needs to be stirred;

[0009] A stirring assembly, mounted on the mounting frame, is used for stirring within the wastewater tank;

[0010] A lifting assembly is mounted on the mounting frame and is used to move the stirring assembly;

[0011] A guide assembly is installed between the mounting frame and the stirring assembly, and the guide assembly is used to ensure stable movement of the stirring assembly;

[0012] The guiding component includes:

[0013] Two slide rail grooves are provided on the mounting bracket.

[0014] Two connecting blocks are provided, and both connecting blocks are connected to the stirring assembly.

[0015] The track wheels are provided in two sets, with each set of track wheels slidably installed in one of the two slide rail grooves, and each set of track wheels is rotatably connected to a connecting block.

[0016] By adopting the above technical solution, the mixing component is installed on the mounting frame through the lifting component and the guide component. The mixing component is used to mix and stir the sewage in the sewage tank. When maintenance or repair of the mixing component is required, the lifting component can be used to lift the mixing component to a suitable position for maintenance without disassembling and removing the mixing equipment from the sewage treatment tank. The structure of two slide rail grooves and two sets of track wheels ensures the stability of the mixing component during the lifting process through the lifting component, and also facilitates the maintenance and repair of the mixing component.

[0017] Optionally, the stirring assembly includes:

[0018] The mounting box is fixedly connected to both of the connecting blocks;

[0019] The motor, with its fixed end fixedly installed inside the mounting box;

[0020] A rotating shaft passes through the mounting box, and one end of the rotating shaft is fixedly installed at the output end of the motor;

[0021] A stirring blade is fixedly installed on the end of the rotating shaft away from the motor.

[0022] By adopting the above technical solution, the installation box is connected to the guide assembly through the connecting block. The motor is installed inside the installation box and drives the stirring fan blades to rotate through the rotating shaft, which stirs the sewage in the sewage tank. This helps to fully mix the various substances in the sewage, improves the efficiency of chemical reactions in the sewage treatment process, ensures that pollutants in the sewage can be treated more thoroughly, and helps to improve the water quality compliance rate.

[0023] Optionally, the lifting assembly includes:

[0024] A fixed pulley, which is rotatably mounted on the mounting bracket;

[0025] A movable pulley, wherein the movable pulley is disposed below the fixed pulley;

[0026] A first chain, one end of which is fixedly mounted on the fixed pulley, the first chain is wound around the movable pulley and then around the fixed pulley, and the other end of which is mounted on the mounting bracket;

[0027] The second chain has one end fixedly mounted on the movable pulley, and the other end of the second chain away from the movable pulley is fixedly mounted on the mounting box.

[0028] By adopting the above technical solution, a pulley block structure is formed by combining fixed pulleys and movable pulleys. According to the principle of the pulley block, this structure is a labor-saving structure. When lifting the mixing component, the operator operates by raising and lowering the first chain. Due to the presence of the movable pulley, the force acting on the first chain will be less than the weight of the mixing component, thus making it easier to lift and lower the mixing component and greatly reducing the operator's workload.

[0029] Optionally, two sets of buffer assemblies are respectively installed at the bottom of the two slide rail grooves, the buffer assemblies including:

[0030] A buffer spring, one end of which is fixedly installed at the bottom of the slide rail groove;

[0031] A buffer block is fixedly installed at the end of the buffer spring away from the slide rail groove.

[0032] By adopting the above technical solution, the track wheels slide rapidly within the slide rail groove during the lifting and lowering process of the mixing component. When the mixing component descends at a high speed or suddenly stops descending, the track wheels will generate a large impact force on the bottom of the slide rail groove. The buffer springs and buffer blocks in the buffer assembly can effectively absorb and buffer this impact force, avoiding direct rigid collision between the track wheels and the bottom of the slide rail groove. This reduces wear, deformation, or damage to the track wheels and the bottom of the slide rail groove caused by frequent impacts, extends the service life of the track wheels and the slide rail groove, and reduces the maintenance cost of the equipment.

[0033] Optionally, the mounting bracket is provided with a retraction assembly, the retraction assembly comprising:

[0034] A roller is rotatably mounted on the mounting frame, and the end of the first chain away from the fixed pulley is fixedly mounted on the roller;

[0035] A handle, which is fixedly mounted on the roller.

[0036] By adopting the above technical solution, the operator can raise and lower the first chain by turning the drum with the handle. Compared with the use of complex electric or hydraulic raising and lowering devices, this raising and lowering assembly consisting of a drum and a handle has a lower cost, is simpler to operate, and reduces the amount of maintenance work caused by electrical faults, hydraulic leaks and other problems.

[0037] Optionally, the roller is provided with a self-locking hole, and the mounting bracket is hinged with a self-locking pin, which is adapted to the self-locking hole.

[0038] By adopting the above technical solution, after the mixing component is adjusted to a suitable height, the self-locking pin is inserted into the self-locking hole of the drum, causing the drum to stop rotating. This effectively prevents the drum from rotating unexpectedly due to misoperation, thereby avoiding safety hazards caused by the sudden raising or lowering of the mixing component. After raising or lowering the mixing component to a specific position, the operator only needs to simply operate the self-locking pin to insert into the self-locking hole to easily keep the mixing component in that position. There is no need to continuously apply external force to maintain the height of the mixing component, reducing the operator's workload.

[0039] Optionally, a diagonal brace is fixedly installed on the mounting bracket.

[0040] By adopting the above technical solution, the diagonal brace greatly enhances the overall structural strength of the mounting frame, enabling it to better withstand the load generated when lifting and lowering the mixing components, and reducing the possibility of deformation or damage to the mounting frame due to excessive force.

[0041] Optionally, a controller is fixedly mounted on the mounting bracket, and a depth sensor is fixedly mounted on the mounting bracket, the depth sensor being electrically connected to the controller.

[0042] By adopting the above technical solution, the depth sensor can monitor the depth position of the mixing component in the sewage tank in real time and transmit the relevant data to the controller. This allows operators to accurately understand the current depth of the mixing component, ensuring that the mixing component is always mixing at the appropriate depth, thereby improving the efficiency and quality of sewage treatment.

[0043] In summary, this application includes at least one of the following beneficial technical effects:

[0044] 1. By setting up a guide component, the stability of the stirring component during the lifting process is enhanced, the swaying of the stirring component during vertical movement is reduced, and the stirring action is made smoother;

[0045] 2. By setting up a lifting component, operators can easily lift and lower the mixing component, greatly reducing the operator's workload;

[0046] 3. By setting up a buffer component, direct rigid collision between the track wheel and the bottom of the slide rail is avoided, which reduces wear, deformation or damage to the track wheel and the bottom of the slide rail caused by frequent impacts, and extends the service life of the track wheel and the slide rail.

[0056] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0057] This application discloses a stirrer fixing device.

[0058] Reference Figure 1 The agitator fixing device includes a mounting frame 1, an agitator assembly 2, a lifting assembly 3, and a guide assembly 4. The mounting frame 1 is fixedly installed on the wall of the sewage tank that needs to be agitated. The agitator assembly 2 is installed on the mounting frame 1 and is used to agitate the sewage tank. The lifting assembly 3 is installed on the mounting frame 1 and is used to move the agitator assembly 2. The guide assembly 4 is installed between the mounting frame 1 and the agitator assembly 2 and is used to ensure the stable movement of the agitator assembly 2.

[0059] In use, the mounting frame 1 is installed on the wall of the sewage tank that needs to be stirred. When the sewage needs to be stirred, the stirring component 2 is lowered to a suitable height by the lifting component 3 according to the depth of the sewage tank and the stirring requirements. The stirring component 2 is then stably moved down to the required height by the guide component 4 to stir the sewage. When the stirring component 2 needs to be maintained or repaired, the stirring component 2 is moved up to the water surface by the lifting component 3 for maintenance, which facilitates the maintenance and repair of the stirring component 2.

[0060] Reference Figure 1 The mounting frame 1 is composed of a rectangular plate at the bottom and two mutually perpendicular square rods fixedly connected at the top, which is used to support and fix the mixing component 2. Diagonal braces 8 are fixedly installed on the two vertical square rods to enhance the overall structural strength of the mounting frame 1.

[0061] Reference Figure 1 and Figure 2 The stirring assembly 2 is mounted on a rectangular plate below the mounting frame 1. The stirring assembly 2 includes a mounting box 21, a motor 22, a rotating shaft 23, and stirring blades 24. The mounting box 21 is slidably connected to the mounting frame 1. The fixed end of the motor 22 is fixedly installed inside the mounting box 21. The rotating shaft 23 passes through the mounting box 21, with one end of the rotating shaft 23 fixedly installed at the output end of the motor 22. The stirring blades 24 are fixedly installed at the end of the rotating shaft 23 away from the motor 22.

[0062] When in use, start the motor 22 inside the installation box 21. The motor 22 drives the rotating shaft 23 to rotate. Due to the rotation of the rotating shaft 23, the stirring blades 24 installed on the rotating shaft 23 also rotate. The stirring blades 24 rotate in the sewage tank, which agitates the sewage, such as suspending solid particles in the sewage and promoting the mixing of sewage and added agents.

[0063] Reference Figure 1 and Figure 2The lifting assembly 3 is mounted on a vertical square rod above the mounting frame 1. The lifting assembly 3 includes a fixed pulley 31, a movable pulley 32, a first chain 33, and a second chain 34. The fixed pulley 31 is rotatably mounted on the mounting frame 1. The movable pulley 32 is located below the fixed pulley 31. One end of the first chain 33 is fixedly mounted on the fixed pulley 31. The first chain 33 is wound around the movable pulley 32 and then wound around the fixed pulley 31. The other end of the first chain 33 is mounted on the mounting frame 1. One end of the second chain 34 is fixedly mounted on the movable pulley 32. The end of the second chain 34 away from the movable pulley 32 is fixedly mounted on the mounting box 21.

[0064] Reference Figure 2 and Figure 3 The guide assembly 4 is mounted on a rectangular plate below the mounting frame 1. The guide assembly 4 includes slide rail grooves 41, track wheels 42, and connecting blocks 43. There are two slide rail grooves 41, which are vertically formed on the mounting frame 1. There are two sets of track wheels 42, with four track wheels 42 in each set. The two sets of track wheels 42 are slidably mounted in the two slide rail grooves 41, and the sliding direction is the same as the direction of the slide rail grooves 41. There are two connecting blocks 43, and both connecting blocks 43 are connected to the stirring assembly 2. Each set of track wheels 42 is rotatably connected to one connecting block 43.

[0065] When in use, start the stirring assembly 2 to start stirring the sewage in the sewage tank. When it is necessary to adjust the height of the stirring assembly 2 in the sewage tank, start the lifting assembly 3 and pull the first chain 33 away from the fixed pulley 31. The movable pulley 32 will move vertically under the cooperation of the fixed pulley 31. Since one end of the second chain 34 is connected to the movable pulley 32 and the other end is connected to the mounting box 21, the movement of the movable pulley 32 will drive the mounting box 21 to move along the slide rail groove 41 of the guide assembly 4 through the second chain 34. During this process, the track wheel 42 rolls in the slide rail groove 41. The connecting block 43 ensures the relative rotation relationship between the track wheel 42 and the stirring assembly 2, so that the stirring assembly 2 rises or falls stably and prevents unstable situations such as tilting or shaking. After the stirring assembly 2 rises or falls to the target height along the guide assembly 4 under the action of the lifting assembly 3, stop the operation of the lifting assembly 3 and the stirring assembly 2 continues to stir at the new height position. When maintenance or repair of the mixing component 2 is required, the lifting component 3 will lift the mixing component 2 above the sewage along the guide component 4 for inspection and repair.

[0066] Reference Figure 2 A buffer assembly 5 is installed at the bottom of the slide rail groove 41. The buffer assembly 5 includes a buffer spring 51 and a buffer block 52. The buffer spring 51 is vertically arranged, and one end of the buffer spring 51 is fixedly installed at the bottom of the slide rail groove 41. The buffer block 52 is fixedly installed at the end of the buffer spring 51 away from the slide rail groove 41.

[0067] During use, if the stirring component 2 descends too quickly and the operator fails to observe the descent distance in time, causing the stirring component 2 to descend rapidly to the bottom of the mounting frame 1, the stirring component 2 will come into contact with the buffer block 52. The buffer spring 51 will be compressed, slowing down the descent speed of the stirring component 2, ensuring the stability of the lifting process, and preventing damage to the stirring component 2 and the mounting frame 1 due to the sudden descent.

[0068] Reference Figure 2 and Figure 4 A retraction assembly 6 is installed on the vertical square rod above the mounting frame 1. The retraction assembly 6 includes a roller 61 and a handle 62. The roller 61 is rotatably mounted on the mounting frame 1. The end of the first chain 33 away from the fixed pulley 31 is fixedly mounted on the roller 61, and the handle 62 is fixedly mounted on the roller 61. A self-locking hole 611 is provided on the roller 61, and a self-locking pin 7 is hinged to the mounting frame 1. The self-locking pin 7 is adapted to the self-locking hole 611 to stop the roller 61 from rotating.

[0069] In use, when it is necessary to raise or lower the mixing assembly 2, the first chain 33 is pulled to achieve this. When it is necessary to raise the height of the mixing assembly 2, the operator holds the handle 62 and rotates the drum 61. As the drum 61 rotates, the first chain 33 wound around the drum 61 is retracted or extended, thereby causing the height of the mixing assembly 2 to rise or fall. When the mixing assembly 2 rises or falls to the target height, the operator stops rotating the handle 62. To ensure that the height of the mixing assembly 2 is fixed, the operator inserts the self-locking pin 7 hinged on the mounting bracket 1 into the self-locking hole 611 of the drum 61, thereby stably maintaining the position and height of the mixing assembly 2.

[0070] Reference Figure 1 and Figure 2 A controller is fixedly mounted on the mounting bracket 1, and a depth sensor 9 is also fixedly mounted on the mounting bracket 1. The depth sensor 9 is electrically connected to the controller. The depth sensor 9 can monitor the depth position of the mixing component 2 in the sewage tank in real time and transmit the relevant data to the controller in the form of an electrical signal. The operator can understand the depth of the mixing component 2 through the controller to ensure that the mixing component 2 is always mixing at the appropriate depth.

[0071] The implementation principle of the agitator fixing device in this embodiment is as follows: During use, the mounting frame 1 is fixed to the wall of the sewage tank, providing a stable support foundation for the entire device. The motor 22 drives the rotating shaft 23 to rotate, and the rotating shaft 23 drives the agitator blades 24 to rotate, thereby agitating the sewage. The fixed pulley 31 is installed on the mounting frame 1, and the movable pulley 32 is below it. Based on the pulley system principle, when the retracting component 6 operates the first chain 33, it can effortlessly raise and lower the agitator component 2 to adapt to the agitation requirements of different depths.

[0072] The guide assembly 4 ensures the stable movement of the mixing assembly 2. Two slide rail grooves 41 are opened on the mounting frame 1, and two sets of track wheels 42 slide in the slide rail grooves 41 respectively. The track wheels 42 slide along the slide rail grooves 41 to provide vertical movement guidance for the mixing assembly 2 and ensure the stability of the movement process.

[0073] The roller 61 is rotatably mounted on the vertical square bar of the mounting frame 1. The operator turns the handle 62 to drive the roller 61 to rotate and retract the first chain 33, thereby raising and lowering the mixing component 2. The self-locking hole 611 on the roller 61 cooperates with the self-locking pin 7 on the mounting frame 1. When the mixing component 2 reaches the target height, the self-locking pin 7 inserts into the self-locking hole 611 to stop the roller 61 from rotating, ensuring that the height of the mixing component 2 is fixed and guaranteeing the accuracy and safety of the mixing operation. In summary, the mixing device allows the mixing component 2 to move smoothly up and down, facilitating the maintenance and repair of the mixing component 2.

[0074] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
