Description

Technical Field

[0001] This utility model relates to the field of bar screen technology, specifically to an air flotation pretreatment elliptical bar screen. Background Technology

[0002] Air flotation technology utilizes the buoyancy of gases to improve liquid treatment efficiency. By introducing air into the water, a large number of tiny bubbles are generated. These bubbles adhere to each other with fine suspended solids, forming flotation particles. The particles rise to the surface using the buoyancy of the bubbles, forming foam or scum, thus achieving solid-liquid separation. Before further treatment, a bar screen is needed to intercept large suspended solids in the wastewater.

[0003] A search revealed a utility model patent with Chinese patent publication number CN222524227U, which discloses an elliptical stacked bar screen, including a bar screen body, a flocculation box fixed to the right side of the bar screen body, a filter box fixed to the right side of the flocculation box, a collection box fixed to the left side of the flocculation box and below the top discharge port of the bar screen body, a bracket fixed to the lower surface of the collection box, a water pump installed on the bracket, and a water delivery pipe fixed to the outlet end of the water pump.

[0004] The aforementioned device uses elliptical plates to push impurities through the holes of the grid. However, impurities at the top of the grid cannot be reached and will be carried back into the holes as sewage flows through, thus affecting the filtration efficiency and leaving room for improvement. Utility Model Content

[0005] The purpose of this utility model is to provide an air flotation pretreatment elliptical bar screen machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an air flotation pretreatment elliptical bar screen machine, comprising a treatment box, a bar screen plate being snapped onto the top of the treatment box, a baffle being fixedly connected to the top of the treatment box, a cleaning assembly being installed inside the baffle, the cleaning assembly being located on top of the bar screen, the cleaning assembly comprising two transmission rods rotatably connected inside the baffle, two symmetrically arranged sprockets being coaxially fixed to the outside of each of the two transmission rods, the two sprockets being fitted with the same chain at the same end, and two pushing brushes being fixedly connected between the two chains, one of the pushing brushes being in contact with the bar screen.

[0007] It can work in conjunction with the elliptical disc to achieve comprehensive cleaning of intercepted impurities, minimizing the possibility of impurity leakage and effectively avoiding the reduction of filtration efficiency due to impurity residue. The motor drives the connected sprocket two to rotate, and sprocket two drives another sprocket two to rotate through chain two. Sprocket two drives two sprockets one to rotate. With the cooperation of the other two sprockets one, the two chains one can start synchronous transmission. The push brush fixed between the two chains one is driven to start moving, and impurities that cannot be reached by the elliptical disc will be pushed to one side.

[0008] As a further preferred embodiment of this technical solution, an installation cover is fixedly installed on the outer wall of one end of the processing box, and a motor is fixedly installed on the outside of the installation cover. A sprocket is coaxially fixed to the output end of the motor and one of the transmission rods, and the two sprockets are fitted with the same chain.

The mounting cover is equipped with a transmission component that is compatible with the mounting rods.

[0010] As a further preferred embodiment of this technical solution, a support assembly is installed on the outside of the processing box. The support assembly includes a support frame fixedly fitted on the outside of the processing box, and a caster wheel is installed at each of the four corners of the bottom of the support frame.

Each of the four screws is rotatably connected to a contact plate at one end of its bottom.

[0012] If the device needs to be moved, the casters at the bottom of the support frame can rotate flexibly, reducing the friction between the device and the ground and making the device easier to move. After the work is completed, the screw is driven to rotate by the knob. Due to the threaded engagement between the screw and the support frame, the screw rotates and moves downward along the support frame. Under the action of static friction, the position of the device will not change easily.

[0013] As a further preferred embodiment of this technical solution, two cleaning brushes are fixedly connected to the inner walls of both ends of the enclosure, and all four cleaning brushes are in contact with the chain.

[0014] As a further preferred embodiment of this technical solution, the thread helix angle of the external thread groove of the screw is smaller than the equivalent friction angle.

[0016] (1) By setting up a cleaning component, this utility model can work in conjunction with the elliptical plate to achieve comprehensive cleaning of intercepted impurities, which can minimize the possibility of impurity leakage and thus effectively avoid the situation of reduced filtration efficiency due to impurity residue. The motor drives the sprocket two connected to it to rotate. The sprocket two drives another sprocket two to rotate through the chain two. The sprocket two drives the two sprockets one to rotate. With the cooperation of the other two sprockets one, the two chains one can start synchronous transmission. The push brush fixed between the two chains one is driven to start moving.

After the work is completed, the screw is driven to rotate by the knob. Since the screw is threaded with the support frame, the screw rotates and moves downward along the support frame. Under the action of static friction, the position of the device will not change easily. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 1As shown in Figure 4, in this embodiment, an air flotation pretreatment elliptical bar screen machine includes a processing box 1, a bar screen plate is snapped onto the top of the processing box 1, a baffle 2 is fixedly connected to the top of the processing box 1, a cleaning component 5 is installed inside the baffle 2, the cleaning component 5 is located on top of the bar screen plate, the cleaning component 5 includes two transmission rods 501 rotatably connected inside the baffle 2, two symmetrically arranged sprockets 502 are coaxially fixed to the outside of the two transmission rods 501, the same chain 503 is sleeved on the two sprockets 502 at the same end, and two push brushes 504 are fixedly connected between the two chains 503, one of the push brushes 504 is in contact with the bar screen plate.

[0025] A mounting cover 7 is fixedly installed on the outer wall of one end of the processing box 1. A motor 507 is fixedly installed on the outside of the mounting cover 7. A sprocket 505 is coaxially fixed to the output end of the motor 507 and one of the transmission rods 501. The two sprockets 505 are fitted with the same chain 506.

[0026] Motor 507 drives sprocket 2 505 connected to it to rotate. Sprocket 2 505 drives another sprocket 2 505 to rotate via chain 2 506. Sprocket 2 505 drives two sprockets 1 502 to rotate. With the cooperation of the other two sprockets 1 502, the two chains 1 503 can start to drive synchronously. The push brush 504 fixed between the two chains 1 503 is driven to start moving. Impurities that cannot be touched by the elliptical plate 4 will be pushed to one side.

[0027] like Figure 1 As shown in Figure 2, the processing box 1 is rotatably connected to several equally spaced mounting rods 3, and several equally spaced elliptical pieces 4 are coaxially fixed to the mounting rods 3. The mounting cover 7 is equipped with a transmission component that is compatible with the mounting rods 3.

[0028] Start the motor 507 outside the mounting cover 7. The motor 507 drives the third sprocket inside the mounting cover 7 that is connected to it. This third sprocket drives several other third sprockets to rotate through the third chain. Subsequently, several mounting rods 3 will be driven by the third sprocket to rotate synchronously. The elliptical plate 4 outside the mounting rod 3 will also rotate. After the protruding part of the elliptical plate 4 passes through the through hole of the grid plate, it can gradually push the impurities to the outside.

[0029] like Figure 2 and Figure 3 As shown, a support assembly 6 is installed on the outside of the processing box 1. The support assembly 6 includes a support frame 601 fixedly sleeved on the outside of the processing box 1. A caster wheel 602 is installed at each of the four corners of the bottom of the support frame 601.

[0030] The support frame 601 has four screws 603 internally threaded, and the four screws 603 are located at the four corners of the support frame 601. Each of the four screws 603 has a contact plate 604 rotatably connected to one end of its bottom.

[0031] If the device needs to be moved, the casters 602 at the bottom of the support frame 601 can rotate flexibly, reducing the friction between the device and the ground and making the device move more easily. After the work is completed, the screw 603 is driven to rotate by the knob. Because the screw 603 is threaded with the support frame 601, the screw 603 rotates and moves downward along the support frame 601. Under the action of static friction, the position of the device will not change easily.

[0032] like Figure 4 As shown, two cleaning brushes 508 are fixedly connected to the inner walls of both ends of the enclosure 2, and all four cleaning brushes 508 are in contact with the chain 503. The cleaning brushes 508 can push out the impurities in the holes of the chain 503, which can prevent the impurities from affecting the normal transmission of the chain 503.

[0033] like Figure 3 As shown, the thread helix angle of the external thread groove of screw 603 is less than the equivalent friction angle, giving it a self-locking property.

[0034] This utility model provides an elliptical bar screen for air flotation pretreatment, the specific working principle of which is as follows:

[0035] When the device is working, sewage flows through pipes to the top grating plate of treatment tank 1. Water passes through the through holes of the grating plate into treatment tank 1, while impurities are intercepted. Simultaneously, the motor 507 outside the mounting cover 7 is started. The motor 507 drives the third sprocket connected to it inside the mounting cover 7. This third sprocket, through a third chain, drives several other third sprockets to rotate. Subsequently, several mounting rods 3 are driven by the third sprockets to rotate synchronously. The elliptical plates 4 outside the mounting rods 3 also rotate. After the protruding parts of the elliptical plates 4 pass through the through holes of the grating plate, they gradually push the impurities outward. At the same time, the motor 507 drives the second sprocket 505 connected to it to rotate. The second sprocket 505 drives another second sprocket 505 to rotate through a second chain 506. 5 drives two sprockets 502 to rotate. With the cooperation of the other two sprockets 502, the two chains 503 can start to drive synchronously. The push brush 504, which is fixed between the two chains 503, is driven to move. Impurities that cannot be touched by the elliptical plate 4 will be pushed to one side. If it is necessary to move the position of the device, the universal wheel 602 at the bottom of the support frame 601 can rotate flexibly, reducing the friction between the device and the ground and making the movement of the device easier. After the work is completed, the screw 603 is driven to rotate by the knob. Due to the threaded engagement between the screw 603 and the support frame 601, the screw 603 rotates and moves downward along the support frame 601. Under the action of static friction, the position of the device will not change easily.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
