Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an air flotation machine which is easy to install and disassemble. Background Art

[0002] Air flotation machine is a water treatment equipment that produces a large number of fine bubbles in the water by the dissolved air system, so that the air is attached to the suspended particles in the form of highly dispersed tiny bubbles, resulting in a state with a density less than that of water. The buoyancy principle is used to make it float on the water surface, thereby achieving solid-liquid separation. Air flotation machines are divided into super-efficient shallow air flotation machines, vortex air flotation machines, and horizontal air flotation machines. They are used in water supply, industrial wastewater and urban sewage treatment. The advantages of air flotation machines are that it is a solid-liquid separation equipment with low investment, extremely small floor space, high degree of automation, and convenient operation and management.

[0003] However, the connectors between the current flotation equipment structures are generally fixed, and the structure is dispersed, occupying a large area, and it is relatively cumbersome to install or disassemble. This causes the outer surface of the equipment to be easily damaged when it needs to be disassembled and repaired later, causing unnecessary losses. In addition, multiple workers are required to support welding during installation, which is a dangerous and impractical method. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide an air flotation machine that is easy to install and disassemble, so as to solve the technical problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: an air flotation machine that is easy to install and disassemble, comprises an air flotation machine body, a first slider, a cavity and a second slider, one side of the air flotation machine body is welded to a support plate, one side of the top of the support plate is welded to a first placement block, one side of the first placement block is rotatably connected to a rotating shaft, the first placement block is rotatably connected to the second placement block through the rotating shaft, the bottom of the second placement block is welded to the first slider, the support plate is provided with a cavity inside, the inner bottom end of the cavity is slidably connected to the second slider, a limiting rod is penetrated inside the second slider, a threaded groove is provided inside the second slider, a threaded rod is threadedly connected to the inner part of the threaded groove, two limiting rods are symmetrically arranged along the central axis of the threaded rod, one end of the threaded rod is welded to a hand crank, a limiting hole is provided at the bottom end of the hand crank, a latch is penetrated inside the limiting hole, and a plurality of slots are provided on one side of the support plate.

[0006] Preferably, compressed gas tanks are installed on the top ends of the first sliding block and the second sliding block, and clamping blocks are installed on the outside of the compressed gas tanks.

[0007] Preferably, a tension spring is welded to the bottom end of the clamping block, and both ends of the tension spring are connected to the clamping block via screws.

[0008] Preferably, the insides of the two groups of clamping blocks are glued with rubber pads, and the rubber pads are made of elastic rubber.

[0011] Preferably, one side of the two groups of clamping blocks is welded to a fixing block, and one side of the fixing block is welded to the air flotation machine body.

[0012] In summary, the utility model mainly has the following beneficial effects:

[0013] 1. Most of the existing compressed gas tanks of air floatation machines are welded. After long-term use, the welds will become loose and broken due to the vibration of the equipment. During installation and disassembly, the steps are relatively cumbersome. If handled improperly, the compressed gas tank is easily dropped and damaged. The utility model places the compressed gas tank on the top of the first slider and the second slider at the top of the support plate through the air floatation machine body, support plate, first slider, cavity, second slider, limit rod, threaded groove and threaded rod. The position of the first slider is fixed, and the second slider can swing up and down through the rotating shaft and the cavity. The threaded rod is connected to one side of the cavity through a bearing. The threaded rod is rotated in the threaded groove opened in the second slider. The second slider can move left and right and contact the first slider. When the second slider is not in contact with the first slider, the first slider swings downward, which is convenient for operators to carry and place the compressed gas tank. When the top of the second slider is against the bottom of the first slider, the first slider drives the second placement block to move upward, which can limit the placed compressed gas tank, thereby facilitating the installation and disassembly of the compressed gas tank on the air floatation machine body. Its structure is simpler and safer.

[0014] 2. After long-term use, the fixed parts of the existing air flotation machine compression cylinder are rusted and loose, and the equipment is prone to wear on the outside of the compression cylinder when it is running. The utility model provides a clamping block, a tension spring, a rubber pad, a through hole, a bolt, a jacket and a fixed block. When the clamping block is placed on the top of the first placement block and the second placement block, the bottoms of the two groups of clamping blocks are welded and connected with two tension springs. The two groups of clamping blocks are both fitted and connected to the outside of the compressed gas tank, and then the through holes on the tops of the two groups of clamping blocks are aligned. By tightening the bolts, the compressed gas tank can be fixed and clamped to prevent the compressed gas tank from moving and falling off, thereby achieving a clamping and protective effect on the compressed gas tank.

A support plate 2 is welded to one side of the air flotation machine body 1, a first placement block 3 is welded to one side of the top of the support plate 2, a rotating shaft 4 is rotatably connected to one side of the first placement block 3, the first placement block 3 is rotatably connected to the second placement block 5 through the rotating shaft 4, and the bottom end of the second placement block 5 is welded to the first slider 6. A cavity 7 is opened inside the support plate 2, and a second slider 8 is slidably connected to the bottom end of the cavity 7. A limiting rod 9 is penetrated inside the second slider 8, a threaded groove 10 is opened inside the second slider 8, and a threaded rod 11 is threadedly connected inside the threaded groove 10. Two limiting rods 9 are symmetrically arranged along the central axis of the threaded rod 11. The threaded rod 11 is rotated, and the second slider 8 slides in the cavity 7. The two limiting rods 9 both penetrate the second slider 8, so that the second slider 8 can keep moving in one direction when moving to prevent deviation.

[0023] See also Figure 1 and Figure 4 It can be seen that a hand crank 12 is welded to one end of the threaded rod 11, and a limiting hole 13 is provided at the bottom end of the hand crank 12. A latch 14 is provided inside the limiting hole 13, and a plurality of slots 15 are provided on one side of the support plate 2. When the threaded rod 11 moves the second slider 8 to a specified position, in order to prevent the threaded rod 11 from rotating due to excessive weight of the equipment, a plurality of slots 15 are provided on one side of the support plate 2. When the hand crank 12 drives the threaded rod 11 to rotate to a certain position, the latch 14 is inserted into the limiting hole 13 at the bottom end of the hand crank 12, and then the latch 14 is inserted into the limiting hole 13, thereby limiting the rotation of the threaded rod 11.

[0024] See also Figure 1 and Figure 3 It can be seen that a compressed gas tank 16 is installed at the top of the first slider 6 and the second slider 8, a clamping block 17 is installed on the outside of the compressed gas tank 16, a tension spring 18 is welded to the bottom of the clamping block 17, both ends of the tension spring 18 are connected to the clamping block 17 by screws, and rubber pads 19 are glued to the inside of the two groups of clamping blocks 17. The material of the rubber pads 19 is elastic rubber. When the two groups of clamping blocks 17 clamp the compressed gas tank 16, the rubber pads 19 are fitted to the outer surface of the compressed gas tank 16, thereby achieving a protective effect and reducing wear.

[0025] The tops of the two groups of clamping blocks 17 are both provided with through holes 20, and the inside of the through holes 20 is meshed and connected with bolts 21. The two groups of clamping blocks 17 are movably connected by the bolts 21. Both sides of the two groups of clamping blocks 17 are welded with jackets 22. One side of the two groups of clamping blocks 17 is welded with a fixing block 23, and one side of the fixing block 23 is welded and connected to the flotation machine body 1.

The jacket 22 can prevent dust and collision on the surface of the compressed gas tank 16.

[0026] The working principle of the utility model is as follows: when the air flotation machine which is easy to install and disassemble is used, the compressed gas tank 16 is placed on the top of the first slider 6 and the second slider 8. The position of the first slider 6 is fixed. The second slider 8 can swing up and down through the rotating shaft 4 and the cavity 7. The threaded rod 11 is connected to one side of the cavity 7 through a bearing. The threaded rod 11 rotates in the threaded groove 10 provided in the second slider 8. The second slider 8 can move left and right and contact the first slider 6. When the second slider 8 is not in contact with the first slider 6, the first slider 6 swings downward, which is convenient for the operator to carry and place the compressed gas tank 16. When the top of the second slider 8 abuts against the bottom of the first slider 6, the first slider 6 drives the second placement block 5 to move upward. The compressed gas tank 16 can be limited by movement, so that the compressed gas tank 16 can be installed and removed on the air flotation machine body 1 conveniently, and its structure is simpler and safer. When the clamping block 17 is placed on the top of the first placement block 3 and the second placement block 5, the bottoms of the two groups of clamping blocks 17 are welded and connected with two tension springs 18. The two groups of clamping blocks 17 are both fitted and connected to the outside of the compressed gas tank 16, and then the through holes 20 on the tops of the two groups of clamping blocks 17 are aligned. The bolts 21 are screwed to fix the compressed gas tank 16 to prevent the compressed gas tank 16 from moving and falling off, thereby achieving the clamping and protection effect of the compressed gas tank 16.
