Description

Technical Field

[0001] This utility model relates to the field of water treatment auxiliary equipment technology, and more specifically, to a submersible mixer installation device. Background Technology

[0002] Hydrolysis acidification tanks are an important component of wastewater treatment systems used in hazardous waste landfills. They are primarily used to remove suspended solids from influent wastewater and improve its biodegradability. Adding submersible mixers to the hydrolysis acidification tank is a common practice. These mixers effectively agitate the wastewater, promoting thorough contact between wastewater and microorganisms, increasing the mixing efficiency of suspended solids and dissolved oxygen, and thus aiding microbial growth and chemical reactions.

[0003] The company currently uses a fixed platform pre-installed in the hydrolysis acidification tank to install submersible mixers. However, in actual production, it has been found that there are difficulties in retrieving and repairing submersible mixers after they malfunction. Moreover, the fixed platform installation means that the installation height of the submersible mixer is fixed. In actual use, it has been found that the submersible mixer is best used at different times at different tank depths for better treatment results. The existing submersible mixers cannot meet the above requirements. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a submersible mixer installation device. This utility model installs the submersible mixer in a housing and connects the housing through a lifting power mechanism, enabling the submersible mixer to have lifting and lowering functions. This utility model can not only meet the mixing operation requirements of the submersible mixer at different pool depths, but also reduce the difficulty of salvage and maintenance, and has high practical application value.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A submersible mixer installation device is provided for installing a submersible mixer in a hydrolysis acidification tank. The device includes four base columns, a housing, and a lifting power mechanism. The four base columns are vertically and fixedly installed within the hydrolysis acidification tank, arranged in a rectangular four-point configuration. The submersible mixer is installed inside the housing, which is fitted into the four base columns. The lifting power mechanism is installed directly above the housing and includes a drum and a cable. One end of the cable is wound around the drum, and the other end is connected to the housing. The lifting power mechanism drives the housing to move along the height of the base columns.

[0007] Furthermore, each of the four corners of the chassis is connected to a sleeve, the inner diameter of which matches the outer diameter of the base column, and the four sleeves are inserted into the four base columns one by one.

[0008] Furthermore, a lifting lug is fixedly installed on the top of the chassis, and the hanging end of the rope is fixedly connected to the lifting lug.

[0009] Furthermore, the submersible mixer is installed inside the casing. The side wall of the casing has a first opening and a second opening.

The impeller of the submersible mixer is exposed on the outside of the second opening. A base assembly is installed at the bottom inside the casing, and the submersible mixer is connected and installed to the base assembly.

[0010] Furthermore, the base assembly includes a fixed base, a movable base plate, and a sealing plate. The fixed base is fixedly installed on the bottom of the inner side of the chassis. The fixed base has an insertion slot and a third opening at one end, which is opened in the direction of the first opening of the chassis. The movable base plate is sized to match the insertion slot and is inserted into the insertion slot. The submersible mixer is fixedly installed on the movable base plate. The sealing plate is connected to the third opening end of the fixed base and can close the third opening. The sealing plate is bolted to the fixed base.

[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] like Figures 1-6The diagram illustrates a submersible mixer installation device for installing a submersible mixer in a hydrolysis acidification tank. It includes four base columns 1, a housing 2, and a lifting mechanism 3. The four base columns 1 are vertically and fixedly installed within the hydrolysis acidification tank, and are fixedly connected to the bottom of the tank. The four base columns 1 are arranged in a rectangular four-point configuration. The submersible mixer is installed inside the housing 2, which is fitted into the four base columns 1. The base columns 1 guide the movement of the housing 2, allowing it to carry the submersible mixer. The lifting mechanism 3 is installed directly above the housing 2 and includes a drum 31. The submersible mixer uses a cable 32, one end of which is wound around a drum 31, and the other end connected to the housing 2. A lifting mechanism 3 drives the housing 2 to move along the height of the base column 1. The cable 32 suspends the housing 2. When the cable 32 is released, the housing 2 naturally sinks due to its own weight, allowing the submersible mixer to move to any depth within the pool to agitate the wastewater. If the submersible mixer malfunctions, the cable 32 can be retrieved via the drum 31, allowing the housing 2 to be lifted to the edge of the hydrolysis acidification tank for easy repair or replacement with a new submersible mixer. Figure 1 As shown, the casing 2 is installed close to the side wall of the hydrolysis acidification tank, and the highest point of the base column 1 is set higher than the highest point of the hydrolysis acidification tank. In this way, the casing 2 can be moved to a position higher than the side wall of the hydrolysis acidification tank, which facilitates the maintenance or replacement of the submersible mixer. After applying this utility model, it can not only meet the mixing operation requirements of the submersible mixer at different tank depths, but also reduce the difficulty of salvage and maintenance, and has high practical application value.

[0027] like Figure 3 As shown, vertically installed pipe sleeves 21 are connected to the four corners of the casing 2. The inner diameter of the pipe sleeve 21 matches the outer diameter of the base column 1. The four pipe sleeves 21 are inserted into the four base columns 1 one by one. The cooperation between the pipe sleeves 21 and the base columns 1 enables the casing 2 to be vertically guided and lifted. Since the contact area between the pipe sleeves 21 and the base columns 1 is large, the base columns 1 also play a role in stabilizing the position of the casing 2, so that the submersible mixer can operate stably in a suspended state.

[0028] like Figure 1 and Figure 4 As shown, a lifting lug 22 is fixedly installed on the top of the chassis 2. The lifting lug 22 is used to connect the end of the cable 32, and the hanging end of the cable 32 is fixedly connected to the lifting lug 22.

[0029] like Figure 4As shown, the casing 2 has a hollow interior, and the submersible mixer is installed inside the casing 2. The side wall of the casing 2 has a first opening 23 and a second opening 24. The first opening 23 is designed as the inlet and outlet for assembling and disassembling the submersible mixer. Therefore, the first opening 23 is directly opposite the wall of the hydrolysis acidification tank. After the casing 2 is raised, the first opening 23 faces the edge of the hydrolysis acidification tank, allowing workers to stand by the edge to inspect or replace the submersible mixer. The second opening 24 is located opposite the first opening 23. After the submersible mixer is installed in the casing 2, its impeller is exposed on the outside of the second opening 24. Therefore, the second opening 24 is mainly to avoid affecting the normal operation of the mixing process. A base assembly 25 is installed at the bottom of the casing 2, and the submersible mixer is connected to the base assembly 25. The base assembly 25 is designed for easy assembly and disassembly, making the disassembly and replacement of the submersible mixer very convenient. The specific structure of the base assembly 25 is as follows: Figure 4 and Figure 5As shown, the base assembly 25 includes a fixed base 251, a movable base plate 254, and a sealing plate 255. The fixed base 251 is fixedly installed on the bottom inner side of the chassis 2. The fixed base 251 has an insertion slot 252. The movable base plate 254 is sized to match the insertion slot 252. One end of the fixed base 251 has a third opening 253, which is opened in the same direction as the first opening 23 of the chassis 2. The third opening 253 and the first opening 23 are in the same direction. A submersible mixer is installed on the movable base plate 254. The water mixer needs to enter and exit through the first opening 23, while the movable base plate 254 enters and exits through the third opening 253. The movable base plate 254 is fitted into the insertion slot 252. The sealing plate 255 is connected to the third opening 253 end of the fixed base 251, and the sealing plate 255 can close the third opening 253. The sealing plate 255 is bolted to the fixed base 251. When replacing the submersible mixer, the sealing plate 255 is not installed, and the third opening 253 remains open to facilitate the entry and exit of the movable base plate 254. After the submersible mixer is installed in place, the sealing plate 255 is fixed in place. Once the sealing plate 255 is fixed, the movable base plate 254 is positioned and fixed in the insertion slot 252 of the fixing seat 251, thus achieving a fixed installation of the submersible mixer. In this utility model, the movable base plate 254 and the submersible mixer are installed together. For maintenance and replacement of the submersible mixer, simply remove the sealing plate 255, pull out the movable base plate 254, and then replace it with a new submersible mixer kit (new movable base plate 254 and new submersible mixer). To facilitate the entry and exit of the movable base plate 254, a handle 256 is vertically installed on the movable base plate 254. The handle 256 can help pull the movable base plate 254. When performing maintenance and replacement operations on the submersible mixer, the machine box 2 is first lifted so that the movable base plate 254 is at the same height as the edge of the hydrolysis acidification tank. This facilitates the removal of the submersible mixer. Since this invention can adopt replacement-type maintenance, the fault repair time of the submersible mixer is greatly shortened, and the sewage treatment operation will not be delayed.

[0030] A submersible mixer mounting device also includes a walking platform 4 for mounting a lifting power mechanism 3, such as... Figure 1 and Figure 2 As shown, this utility model designs a walking platform 4, which is installed across the top of the hydrolysis acidification tank. A roller platform 41 is fixedly connected to the side of the walking platform 4, and a lifting power mechanism 3 is installed on the roller platform 41. The installation height of the roller platform 41 is higher than the highest point of the four base columns 1. The walking platform 4 can be used to install the lifting power mechanism 3 and can also be used for daily walking by sewage system management personnel, achieving two goals at once. Sewage system management personnel can perform sewage sampling and other operations on the walking platform 4.

[0031] like Figure 2As shown, the lifting power mechanism 3 also includes a motor 33 and a reducer 34. The output shaft of the motor 33 is connected to the input end of the reducer 34, and the output end of the reducer 34 is connected to the drum 31. The motor 33 provides rotational power to the drum 31, and the reducer 34 can reduce the output speed and increase the output torque, enabling the drum 31 to rotate normally. In order for the submersible mixer to stop at the required pool depth, this invention has installed a brake 35 on the output shaft of the motor 33. The brake 35 acts as a brake, which can brake the drum 31, enabling the submersible mixer to stop at the required pool depth. The mixer operates at a suitable pool depth. Because the wastewater in the hydrolysis acidification tank is turbid, it is difficult to directly observe the position of the submersible mixer. Therefore, this invention indirectly determines the position of the submersible mixer by binding an identification tape 321 to the rope 32. The identification tape 321 is set at equal intervals and uses a bright color for easy observation. In actual application, a depth level is generally half a meter, so an identification tape 321 is set at half-meter intervals. The identification tape 321 is thin and does not affect the operation of the rope 32.

[0032] In the above embodiments, the present invention is installed in a hydrolysis acidification tank for application. However, the present invention is not limited to application in hydrolysis acidification tanks, but can also be applied in other tank scenarios where submersible mixers are installed.

[0033] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
