Description

Technical Field

[0001] The utility model belongs to the technical field of sewage pool floating object salvaging equipment, in particular to a sewage pool liquid surface floating object salvaging device. Background Art

[0002] In the sewage treatment pool of the farm, there is usually a large amount of debris floating on the surface of the sewage pool, so it is necessary to manually salvage the floating objects regularly to prevent the floating objects from affecting the subsequent treatment of the sewage. The floating objects floating on the surface of the sewage pool are usually relatively scattered, and workers need to salvage them around the sewage pool. The salvage process is relatively long and very time-consuming and labor-intensive. The existing surface floating object salvage device usually uses a net bag to collect floating objects, but the net bag is very easy to be blocked and needs to be cleaned after several uses. Not only does it affect the salvage efficiency, but the net bag is not easy to clean. It needs to be repeatedly flushed on both sides of the net bag. The sewage splashes everywhere during the cleaning process, and the operating environment is relatively harsh. Utility Model Content

[0003] In order to solve the deficiencies of the prior art, the utility model provides a sewage pool liquid surface floating object salvaging device, which can not only automatically salvage the floating objects on the sewage pool liquid surface, but also does not require special regular cleaning of the equipment.

[0004] In order to achieve the purpose of this utility model, the following scheme is proposed:

[0005] A device for salvaging floating objects on the liquid surface of a sewage pool comprises a support frame, a roller and a material receiving trough.

[0006] Roller assemblies are provided at both ends of the support frame, and rollers are provided at the bottom of the roller assemblies, and the direction of the rolling axis thereof is consistent with the length direction of the support frame. The rollers are used to connect the tracks on the two ground surfaces of the sewage pool.

[0007] The two ends of the drum are rotatably connected to the bottom of the two ends of the support frame. The drum is driven by a motor. The drum is parallel to the support frame. The axis of the drum is located below the liquid level of the sewage pool, and the top surface of the drum is located above the liquid level of the sewage pool. Both ends of the drum are coaxially provided with end plates of circular structure, whose outer diameter is larger than the outer diameter of the drum. The outer wall of the drum is provided with multiple V-shaped grooves along a circumferential array, and its length direction is consistent with the axis of the drum. A flat plate is rotatably provided on the side of the V-shaped groove facing away from the rotation direction of the drum, and its rotation axis is parallel to the axis of the drum. An elastic member is provided between the side of the V-shaped groove facing the rotation direction of the drum and the back of the flat plate; when the elastic member is in a natural state, the front of the flat plate fits with the side of the V-shaped groove facing away from the rotation direction of the drum, and at this time, the angle between the tangent direction at the intersection of the outer surface of the drum and the flat plate and the front of the flat plate is an acute angle; when the edge of the flat plate fits with the side of the V-shaped groove facing the rotation direction of the drum, the elastic member is in a compressed state, and at this time, the distance between the front of the flat plate and the axis of the drum is less than the radius of the drum.

[0008] The material receiving trough is connected to the bottom of the support frame. Along the moving direction of the support frame when salvaging floating objects, the material receiving trough is located behind the drum. The rotation direction of the top of the drum is opposite to the direction of the support frame when salvaging floating objects. The front end of the bottom plate of the material receiving trough is in sliding contact with the outer wall of the top of the drum. The bottom plate is located above the liquid level of the sewage pool and lower than the top surface of the drum.

[0009] The beneficial effects of the utility model are as follows: the scheme utilizes the roller to collect all floating objects on the liquid surface of the sewage pool in the receiving trough, so that the operator can more centrally clean the floating objects in the receiving trough to improve the salvage efficiency, and the cleaning work of the docking trough is also completed during the cleaning, without the need to specially clean the docking trough; and the roller can also achieve the purpose of cleaning by continuously rotating in the sewage, and the side of the flat plate used for salvaging floating objects can also be automatically cleaned by contact with the bottom plate.

DETAILED DESCRIPTION

[0014] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0015] like Figure 1 , Figure 2 As shown, a device for salvaging floating objects on the liquid surface of a sewage pool comprises: a support frame 1, a roller 3 and a material receiving trough 5.

[0016] Specifically, roller assemblies 2 are provided at both ends of the support frame 1, and rollers 21 are provided at the bottom of the roller assemblies 2, whose rolling axis direction is consistent with the length direction of the support frame 1, and the rollers 21 are used to connect the tracks on the two surfaces of the sewage pool.

[0017] Specifically, the two ends of the drum 3 are rotatably connected to the lower ends of the support frame 1, the drum 3 is driven by a motor, the drum 3 is parallel to the support frame 1, the axis of the drum 3 is located below the liquid surface of the sewage pool, and the top surface of the drum 3 is located above the liquid surface of the sewage pool, and the two ends of the drum 3 are coaxially provided with end plates 31 of circular structure, whose outer diameter is larger than the outer diameter of the drum 3, and the outer wall of the drum 3 is provided with a plurality of V-shaped grooves 32 along the circumferential array, and the length direction of the V-shaped groove 32 is consistent with the axis of the drum 3, and a flat plate 4 is rotatably provided on the side of the V-shaped groove 32 facing away from the rotation direction of the drum 3, and its rotation axis is parallel to the axis of the drum 3, and an elastic member 41 is provided between the side of the V-shaped groove 32 facing the rotation direction of the drum 3 and the back side of the flat plate 4; when the elastic member 41 is in a natural state, the front side of the flat plate 4 is in contact with the side of the V-shaped groove 32 facing away from the rotation direction of the drum 3, and at this time, the angle between the tangent direction at the boundary line between the outer surface of the drum 3 and the flat plate 4 and the front side of the flat plate 4 is an acute angle, that is, Figure 2 As shown, the angle between the front face of the plate 4 and the dotted arrow is an acute angle, and the dotted arrow is a tangent passing through the boundary between the outer surface of the drum 3 and the plate 4, so as to facilitate the upward salvage of floating objects; when the edge of the plate 4 is in contact with the side of the V-shaped groove 32 facing the rotation direction of the drum 3, the elastic member 41 is in a compressed state, and at this time, the distance between the front face of the plate 4 and the axis of the drum 3 is less than the radius of the drum 3.

[0018] Specifically, the receiving trough 5 is connected to the bottom of the support frame 1. Along the moving direction of the support frame 1 when salvaging floating objects, the receiving trough 5 is located behind the drum 3. The rotation direction of the top of the drum 3 is opposite to the direction of the support frame 1 when salvaging floating objects. Figure 2 As shown, when salvaging floating objects, the support frame 1 moves to the right side of the view, and the drum 3 rotates counterclockwise along the direction of the arc arrow in the view, so the rotation direction of the top of the drum 3 is to the left, which is opposite to the moving direction of the support frame 1, and the receiving trough 5 is located on the left side of the drum 3, that is, behind the moving direction of the support frame 1, and the front end of the bottom plate 51 of the receiving trough 5 is in sliding contact with the outer wall of the top of the drum 3, and the bottom plate 51 is located above the liquid level of the sewage pool and lower than the top surface of the drum 3. The purpose of the bottom plate 51 being higher than the liquid level is to facilitate the salvage of floating objects in the receiving trough 5 and prevent the sewage from dispersing the floating objects in the receiving trough 5. The purpose of making the bottom plate 51 lower than the top surface of the drum 3 is to facilitate the discharge of floating objects between the outer wall of the drum 3 and the flat plate 4 into the receiving trough 5.

[0019] During salvage, the support frame 1 is moved along the tracks on the two floors of the sewage pool, and the support frame 1 can be moved by the motor-driven roller 21; during the movement of the support frame 1, the drum 3 is always in a rotating state. When the front end of the flat plate 4 is exposed to the water surface, the floating objects in front of the drum 3 will be gradually lifted up, and the front of the flat plate 4 and the outer wall of the drum 3 and the end plates 31 at both ends will form a closed salvage frame, so that the floating objects are surrounded between the salvage frames. Through the rotation of the drum 3, the floating objects will be driven to pass over the top of the drum 3 and turn over to the receiving trough 5. Since the front end of the bottom plate 51 is in sliding contact with the outer wall of the drum 3, the floating objects on the outer wall of the drum 3 can be smoothly slid onto the bottom plate 51. When the flat plate 4 is ready to pass over the bottom plate 51, the flat plate 4 will swing in the opposite direction of the rotation of the drum 3 under the resistance of the front end of the bottom plate 51. In this process, the elastic member 41 will be compressed, and the front end of the bottom plate 51 can be used to completely scrape off the floating objects on the front of the flat plate 4, so as to achieve the purpose of automatically cleaning the flat plate 4. After the flat plate 4 completely passes over the bottom plate 51, the flat plate 4 will be stretched out again under the action of the elastic member 41 to facilitate the next salvage work. The present solution uses the roller 3 to collect all floating objects on the surface of the sewage pool in the receiving trough 5, so that the operator can more centrally clean the floating objects in the receiving trough 5, and the cleaning work of the docking trough 5 is also completed while cleaning, without the need to clean the docking trough 5 specifically; and the roller 3 can also achieve the purpose of cleaning by continuously rotating in the sewage, and the side of the flat plate 4 used for salvaging floating objects can also be automatically cleaned by contacting with the bottom plate 51.

[0020] Preferably, the height of the roller assembly 2 relative to the support frame 1 is adjustable to facilitate controlling the relative height position between the drum 3 and the liquid level of the sewage pool and to enable the drum 3 to adapt to liquid levels of different heights.

[0021] Further preferably, Figure 1 , Figure 2 As shown, the roller assembly 2 also includes a mounting plate 22, and the roller 21 is arranged below the mounting plate 22. A plurality of guide rods 11 are vertically arranged at both ends of the top surface of the support frame 1. The guide rods 11 at both ends of the support frame 1 vertically pass through the mounting plate 22 at the corresponding end of the support frame 1 respectively. An adjusting screw 23 is vertically passed through the mounting plate 22, and its lower end is rotatably connected to the top of the support frame 1. By rotating the adjusting screw 23, the mounting plate 22 can be driven to rise and fall along the guide rod 11, so as to achieve the purpose of adjusting the height of the roller assembly 2 relative to the support frame 1.

[0022] Preferably, Figure 1 As shown, a driving motor 33 is provided at one end of the top of the support frame 1, and its main shaft is connected to the rotating shaft of the roller 3 through a belt transmission structure to achieve the purpose of motor driving the roller 3.

[0023] The above is only a preferred embodiment of the utility model, and does not mean that it is the only one or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
