Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a liftable packing device. Background Technique

[0002] With the increasing attention paid to the environment by people, the treatment and discharge of sewage have received more and more extensive attention; at present, the sewage in cities in China can basically be comprehensively and effectively treated, while the domestic sewage in rural areas and towns in China generally still lacks effective treatment; the rural population in China accounts for a large proportion of the total population, and the untreated rural sewage will pollute river channels and underground water bodies.

[0003] Packing is a commonly used auxiliary in sewage treatment equipment. It is cheap and has good use effect. It is mainly used in the contact oxidation process. Microorganisms will adhere and accumulate on the surface of the packing material to increase the contact surface with sewage, degrade the sewage, and then improve the biodegradability of wastewater.

[0004] The packing device is mainly used for sewage treatment. The packing material is installed on the packing device, and then the packing device is placed in the sewage treatment pool to adsorb microorganisms in the sewage. However, most of the current packing devices are fixedly installed in the sewage treatment pool, and the packing material needs to be cleaned and replaced regularly. Each time, the packing device fixed in the sewage pool needs to be disassembled before the packing device can be removed from the sewage treatment pool, which is not convenient for the maintenance and cleaning and replacement of the packing device. Content of the Utility Model

[0005] In order to overcome the defects of the above-mentioned prior art pointed out, the inventor of the present invention has conducted in-depth research and completed the present invention after a large amount of creative labor.

[0006] Specifically, the technical problem to be solved by the present invention is: to provide a liftable packing device to solve the technical problem that the current packing device is fixed in the sewage treatment pool, which is not conducive to later maintenance and cleaning and replacement.

[0007] To solve the above technical problem, the present invention provides the following technical solution:

[0008] A liftable packing device, in which a rack for packing is arranged in a lifting manner inside the sewage treatment pool, lifting components for lifting the rack are installed on both sides of the sewage treatment pool, and the movable ends of the lifting components are in contact with both ends of the rack;

[0009] The lifting assembly includes a U-shaped frame, inside which a winding assembly is rotatably installed. A lifting rope is wound around the winding assembly, and one end of the lifting rope away from the winding assembly is fixedly connected to a lifting plate, and the lifting plate is slidably limited inside the sewage treatment tank.

[0010] The material rack includes a frame, on both sides of which a contact plate is welded, and the bottom of the contact plate is in contact with the top of the lifting plate.

[0011] As an improved technical solution, the lifting assembly further includes two guide seats B fixed on the inner wall of the sewage treatment tank. A guide groove B is provided on the guide seat B, and a guide block B that slides inside the guide groove B is welded on one side of the lifting plate close to the guide seat B.

[0012] As an improved technical solution, the driving end of the winding assembly is fixedly connected to the driving shaft of a servo motor, and a cushion seat is fixedly connected to the bottom of the servo motor.

[0013] As an improved technical solution, the lifting assembly further includes two limit wheels B and one limit wheel A. The two limit wheels B are respectively installed on both sides of the side wall of the sewage treatment tank relatively, and the limit wheel A is installed on the top of the side wall of the sewage treatment tank and is arranged corresponding to the two limit wheels B. A limit guide cavity for limiting the lifting rope is formed by the two limit wheels B and the limit wheel A.

[0014] As an improved technical solution, the frame includes two hollow frames, and the two hollow frames are welded together by vertical bars. A plurality of cross braces are welded inside the hollow frame, and a material rod for fixing packing materials is welded between adjacent cross braces.

[0015] As an improved technical solution, side plates are welded on both sides of the opposite surfaces of the two hollow frames, and the contact plate is welded at the position close to the bottom on the outside of the side plate.

[0016] As an improved technical solution, two triangular blocks for supporting the contact plate are welded between the upper surface of the contact plate and the side plate. An arc-shaped groove for the lifting rope to pass through is provided at one end of the contact plate close to the lifting assembly.

[0017] As an improved technical solution, guide seats A are installed on all four sides of the inner wall of the sewage treatment tank. A guide groove A is provided on the guide seat A, and a guide block A that slides inside the guide groove A is welded on the outside of the hollow frame.

[0018] After adopting the above technical solution, the beneficial effects of the present utility model are:

[0019] When the rack needs to be cleaned, the continuous winding of the lifting rope will drive the lifting plate to move upward, moving the rack out of the inside of the sewage treatment tank. Then, the crane is used to transport the rack. The rack has changed the traditional installation method and is directly mounted on the tops on both sides and limited between multiple guide seats A, restricting it inside the sewage treatment tank. The lifting component can drive the rack to lift, facilitating the later maintenance, repair, cleaning, or replacement of the rack. The guide block A slides inside the guide groove A. The cooperation of multiple guide blocks A and the guide groove A enables the rack to only perform vertical linear lifting when inside the sewage treatment tank. On the one hand, it ensures that the rack can accurately reach the predetermined position, and on the other hand, it can improve the running stability of the rack. Description of the Drawings

[0032] As Figures 1 to 5 As commonly shown, the present invention provides a liftable packing device, including a sewage treatment tank 1 for storing sewage. A material rack 3 for packing is arranged in the sewage treatment tank 1 in a lifting manner. Lifting components 2 for lifting the material rack 3 are installed on both sides of the sewage treatment tank 1, and the movable ends of the lifting components 2 are in contact with both ends of the material rack 3;

[0033] The lifting component 2 includes a U-shaped frame 23. A winding component 24 is rotatably installed inside the U-shaped frame 23. A suspension rope 27 is wound around the winding component 24. One end of the suspension rope 27 away from the winding component 24 is fixedly connected to a lifting plate 211, and the lifting plate 211 is slidably limited inside the sewage treatment tank 1;

[0034] The material rack 3 includes a frame. Contact plates 36 are welded on both sides of the frame, and the bottom of the contact plate 36 is in contact with the top of the lifting plate 211.

[0035] A liftable packing device according to an embodiment of the present utility model. When it is necessary to clean the material rack 3, the servo motor 22 drives the winding assembly 24 to rotate to wind up the lifting rope 27. The continuous winding of the lifting rope 27 will drive the lifting plate 211 to move upward. Since the material rack 3 is carried between the tops of the two lifting plates 211, the upward movement of the lifting plate 211 will slowly lift the material rack 3 upward and move the material rack 3 out of the interior of the sewage treatment tank 1. Then, the hook of the crane hooks the steel cable on the material rack 3, and the material rack 3 is transported by the crane. The material rack 3 changes the traditional installation method, is directly carried on the top of the lifting plate 211, and is limited between multiple guide seats A4, and is restricted inside the sewage treatment tank 1. The lifting assembly 2 can drive the material rack 3 to lift, which is convenient for later maintenance, repair or cleaning and replacement of the material rack 3.
