Technical Field

[0001] This utility model belongs to the field of spray tower technology, specifically relating to a filter frame installation structure for a cyclone spray tower. Background Technology

[0002] Cyclone spray towers are widely used wet waste gas purification devices in industrial production, which can effectively treat various waste gas pollutants such as grinding dust, acid and alkali mist, and paint mist.

[0003] Existing cyclone spray tower filter frames in water storage tanks are mostly installed using built-in fixed or top-suspended methods. Cleaning the filter residue requires emptying the tank of chemicals and opening the top cover before work can begin. This not only makes maintenance cumbersome and causes long equipment downtime, but also easily leads to chemical waste and poses safety hazards for operators coming into contact with corrosive liquids. It fails to meet the requirements of efficient operation and maintenance. Therefore, there is an urgent need for a cyclone spray tower filter frame installation structure that allows for convenient pull-out maintenance and reliable positioning. Utility Model Content

[0004] This utility model features a hinged inspection window on the side wall of a water storage tank, along with a bottom support frame equipped with roller slides and limiting grooves, and a top guide frame that only restricts lateral displacement and does not constrain vertical sinking. This enables the filter frame to be pulled out laterally for maintenance and to be stably positioned in its working position, thereby solving the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: a filter frame installation structure for a cyclone spray tower includes a water storage tank and a filter frame, and further includes: An inspection window is hinged to the side wall of the water storage tank, and a filter frame is slidably installed inside the water storage tank at the location corresponding to the inspection window. A support frame is installed inside the water storage tank and extends along the pull-out direction. The support frame includes a bottom support frame and a top guide frame. Rollers are located on both sides of the bottom of the filter frame. The bottom support frame has a slide rail adapted to the rollers. A limit groove is provided on the slide rail at the working position of the filter frame. The top guide frame is used to limit the lateral displacement of the filter frame without restricting its vertical downward sinking.

[0006] The present invention is further configured such that the limiting groove is an arc-shaped recess.

[0007] The present invention is further configured such that the connection between the limiting groove and the slide is a circular arc transition.

[0008] The present invention is further provided that the filter frame is provided with a handle on the side facing the inspection window.

[0009] The present invention is further configured such that the inspection window is a flip-top structure, with a hinged lower part that is hinged to the side wall of the water storage tank, and a free upper part, and a sealing strip is provided around the perimeter of the inspection window.

[0010] The present invention is further configured such that the inspection window is made of transparent material.

[0011] The present invention is further configured such that the top guide frame is a symmetrically arranged lateral guide plate, and the inner side of the lateral guide plate slides in cooperation with the side wall of the top of the filter frame.

[0012] By adopting the above technical solution, the beneficial effects that this utility model can achieve are: 1. The maintenance window hinged to the side wall of the water storage tank works in conjunction with the side-pull-out filter frame, allowing the filter residue cleaning operation to be completed without emptying the liquid in the tank, thus improving the operation and maintenance efficiency of the filter frame.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-3 : Example 1:

[0018] This embodiment provides a filter frame installation structure for a cyclone spray tower, including a water storage tank 1 and a filter frame 2, and further including: Inspection window 3 is hinged to the side wall of the water storage tank 1, and a filter frame 2 is slidably installed in the water storage tank 1 corresponding to the inspection window 3. A support frame 4 is installed inside the water storage tank 1 and extends along the pull-out direction. The support frame 4 includes a bottom support frame 40 and a top guide frame 41. Rollers 5 are located on both sides of the bottom of the filter frame 2. The bottom support frame 40 is provided with a slide rail 6 that is adapted to the rollers 5. A limit groove 7 is provided at the working position of the slide rail 6 corresponding to the filter frame 2. The top guide frame 41 is used to limit the lateral displacement of the filter frame 2 without restricting its vertical downward sinking.

[0019] The cyclone spray tower filter frame 2 installation structure described in this embodiment is installed inside the water storage tank 1 that is matched with the cyclone spray tower. The water storage tank 1 is used to receive and store the washing liquid that flows back from the spray tower. The installation structure is used to support and position the filter frame 2, so as to realize the interception of impurities in the flowing liquid and facilitate maintenance.

[0020] The side wall of the water storage tank 1 has an inspection port that communicates with the internal cavity. An inspection window 3 is provided at the inspection port. The inspection window 3 is a rectangular plate structure with a flip-top arrangement. Its lower part serves as a hinge 9, which is rotatably connected to the side wall of the water storage tank 1 below the inspection port through a hinge shaft. Its upper part serves as a free part, which can be flipped outward around the hinge shaft. The inner side of the inspection window 3 is inlaid with a sealing strip. When the inspection window 3 is closed, the sealing strip is tightly attached to the side wall of the water storage tank 1 around the inspection port, so as to achieve a seal inside the water storage tank 1 and prevent liquid or water vapor from overflowing. The window of the inspection window 3 is made of a transparent material, which can be any one of tempered glass, transparent polypropylene sheet, or polycarbonate sheet. Operators can directly observe the sludge condition of the filter frame 2 inside the water storage tank 1 without opening the inspection window 3 and determine whether cleaning and maintenance are required.

[0021] The water storage tank 1 is equipped with a support frame 4 extending along the pull-out direction of the filter frame 2. The support frame 4 is divided into two parts: a bottom support frame 40 and a top guide frame 41. Two sets of bottom support frames 40 are symmetrically arranged on the inner bottom surface of the water storage tank 1. The bottom support frame 40 is a long strip structure, and its bottom can be fixedly connected to the bottom wall of the water storage tank 1 by bolts or welding. Each set of bottom support frames 40 has a recessed slide 6 on its top surface, extending along the length of the bottom support frame 40. The cross-section of the slide 6... The surface shape is adapted to the roller 5 at the bottom of the filter frame 2, which can constrain the rolling path of the roller 5 and prevent the roller 5 from deviating to the left or right; the slide 6 is recessed downward at the normal working position of the filter frame 2 to form a limiting groove 7. The limiting groove 7 is an arc-shaped recess, and its concave curvature matches the outer circumference of the roller 5, which can accommodate the roller 5 to fall into it to realize the position limitation of the filter frame 2. The connection between the limiting groove 7 and the two ends of the slide 6 is treated with arc transition, so that the roller 5 can slide smoothly into and out of the limiting groove 7 and avoid jamming.

[0022] Two sets of top guide frames 41 are symmetrically arranged in the upper space inside the water storage tank 1, corresponding vertically to the two sets of bottom support frames 40 below. The top guide frames 41 extend along the pulling direction of the filter frame 2, and their two ends can be fixed to the opposite inner sidewalls of the water storage tank 1 by welding or bolting. The top guide frames 41 adopt the structure of lateral guide plates. Both lateral guide plates are arranged vertically, and the inner sides of the plates are set opposite each other, corresponding to the left and right sidewalls of the top of the filter frame 2. A small assembly gap is reserved between them. When the filter frame 2 moves along the pulling direction, its top sidewall can slide along the inner side of the plate, thereby limiting the lateral displacement of the filter frame 2 and ensuring the stability of the pulling process. The top of the lateral guide plates is not provided with a shielding or pressing structure. The filter frame 2 has no upper constraint in the vertical direction. When the roller 5 slides into the limiting groove 7 and causes the filter frame 2 to sink slightly, the top of the filter frame 2 can move freely downward between the two plates without structural interference.

[0023] The filter frame 2 has a rectangular frame structure with through-holes evenly distributed on its side walls and bottom. The inside of the frame forms a closed slag collection chamber. When the return liquid flows through the filter holes into the water storage tank 1, the solid impurities carried in the liquid are intercepted and retained in the slag collection chamber. Rollers 5 are installed on the left and right sides of the bottom of the filter frame 2, with at least two rollers 5 on each side. They are arranged back and forth along the pulling direction. The rollers 5 are rotatably connected to the bottom side wall of the filter frame 2 through pins. The rollers 5 can rotate freely around the pins and move along the slide rail 6 in the form of rolling friction to reduce the pulling resistance. A handle 8 is fastened to the end face of the filter frame 2 facing the inspection window 3 by bolts. The operator can hold the handle 8 to apply pulling or pushing force to complete the pulling and resetting operation of the filter frame 2.

[0024] When the equipment is operating normally, the filter frame 2 is in the working position inside the water storage tank 1. The bottom roller 5 falls into the limiting groove 7 of the slide 6, and the filter frame 2 maintains a stable position by its own weight. The lateral guide plate at the top restricts the lateral movement of the filter frame 2. The liquid returning from the spray tower falls into the filter frame 2, is filtered through the filter holes on the side wall and bottom, and then flows into the water storage tank 1. Solid impurities are retained inside the filter frame 2. When it is necessary to clean the filter residue, the operator checks the state of the residue through the transparent inspection window 3, flips the inspection window 3 outward, and pulls the filter frame 2 outward by holding the handle 8. The roller 5 is pulled and slides out of the plane of the slide 6 along the arc transition surface of the limiting groove 7, and then continues to roll outward along the slide 6. During the pulling process, the lateral guide plate at the top always restricts the left and right deviation of the filter frame 2 to ensure a smooth pulling action. After the filter frame 2 is completely pulled out of the water storage tank 1, the filter residue inside can be emptied and cleaned. After cleaning, push the filter frame 2 into the slide rail 6. The roller 5 rolls inward along the slide rail 6. When it reaches the working position, the roller 5 smoothly slides into the arc-shaped recessed limiting groove 7 along the arc transition surface. The filter frame 2 sinks slightly in sync with the roller 5. The top side guide plate does not obstruct the sinking action, and the filter frame 2 is stably kept in the working position. Finally, flip it inward to close the inspection window 3. The sealing strip adheres to the side wall of the water storage tank 1 to achieve a seal, and the equipment can be restored to normal operation.

[0025] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
