[0014] Figure 2 It is Figure 1 An enlarged view of A in figure 2. DETAILED DESCRIPTION
[0015] The technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.
[0016] It is to be understood that the structure, proportion, size and the like shown in the drawings of the present application are only used to cooperate with the disclosed content, so that those skilled in the art can understand and read, and are not used to limit the implementation of the present application. Therefore, any modification of the structure, change of the proportion relationship or adjustment of the size, without affecting the effect and purpose of the present application, should still fall within the scope of the disclosed technology.
[0017] As shown in Figure 1 and Figure 2 The present application is a floating ball type water bubble elimination device, which comprises a hollow tank body 11 with a top opening arranged in a sewage treatment device 10, and a hollow telescopic sleeve 12 arranged in the tank body 11 with upper and lower openings. The lower end of the telescopic sleeve 12 is fixed in the tank body 11, and a floating body 13 is connected at the top opening. The telescopic sleeve 12 is composed of a plurality of elastic telescopic joints 121. The telescopic sleeve 12 can be a thin-walled plastic telescopic sleeve or a thin-walled rubber telescopic sleeve. The floating body 13 is made of plastic material. The plastic floating body has a large buoyancy in water. Among them, the floating body 13 and the telescopic sleeve 12 have a water inlet gap 14 for liquid to flow into the telescopic sleeve 12. A water pumping mechanism 20 is connected at the bottom of the tank body 11 for pumping liquid in the telescopic sleeve and discharging the liquid.
[0018] In this way, the floating body is placed in the sewage treatment device 10, and due to the buoyancy, the floating body floats on the liquid surface, and the water inlet gap 14 is at the liquid level position. During operation, the water pumping mechanism 20 is started, and the liquid and the foam on the liquid surface flow into the telescopic sleeve 12 through the water inlet gap 14 and are pumped away by the water pumping mechanism 20, thereby achieving the purpose of eliminating foam. Moreover, the floating body 13 can float on the liquid surface and adjust the telescopic sleeve flexibly, so as to ensure that the water inlet gap is always at the liquid level position. When the liquid level rises, the floating body rises under the action of the buoyancy and drives the telescopic sleeve to elongate, and when the liquid level drops, the floating body drops and the telescopic sleeve contracts and shortens under the action of its own gravity, thereby ensuring that the water gap is always at the liquid level position, ensuring the continuity and stability of the water pumping mechanism when pumping water. At the same time, it avoids the situation that the water pumping mechanism cannot pump water due to the drop of the liquid level, thereby causing the equipment to be damaged due to idling.
[0019] In this embodiment, the water inlet gap 14 is provided with a filter screen 15. Specifically, the water inlet gap 14 is formed between the telescopic sleeve 12 and the float 13, and the telescopic sleeve and the float 13 are connected together by the filter screen 15. The filter screen can not only intercept impurities in the liquid to prevent the impurities from entering the water pumping mechanism and causing blockage or wear, but also break foam during the flow of the liquid.
[0020] The sewage treatment device 10 is divided into two aeration chambers 101 and one decanting chamber 102. The two aeration chambers 101 and the decanting chamber 102 are communicated with each other. The tank body 11 is fixed in one of the aeration chambers 101 by a support rod 103. Specifically, the support rod 103 is vertically arranged, and the end thereof is fixed to the bottom of the aeration chamber 101, and the tank body 11 is fixed to the upper end of the support rod 103.
[0021] The water pumping mechanism 20 includes a pump 21 located outside the sewage treatment device 10, a water pumping pipeline 22 connected to the inlet of the pump, and a drainage pipeline 23 connected to the outlet of the pump. All the aeration chambers 101 and the decanting chamber 102 are connected to the water pumping pipeline 22 by branch pipelines 24. The second valves 25 are connected to all the branch pipelines 24. The outlet end of the drainage pipeline 23 is connected to the side of the decanting chamber 102, and the blowdown valve 28 and the third valve 26 are connected to the drainage pipeline 23. The first valve 271 is connected to the connecting pipeline 27 at the bottom of the tank body 11. In this way, when the first valve 271 and the blowdown valve 28 are opened and the pump 21 is started, the liquid flows into the telescopic sleeve 12 through the water inlet gap 14 and the filter screen 15, and then enters the water pumping pipeline 22 through the connecting pipeline 27, and is pumped by the pump 21 and discharged from the sewage treatment device through the blowdown valve 28 of the drainage pipeline 23. Of course, the third valve 26 can be opened and the blowdown valve 28 can be closed, the liquid is pumped by the pump 21, and then enters the decanting chamber 102 through the drainage pipeline 23 to circulate, so as to eliminate the foam, and the sewage is not reduced in the process of eliminating the foam.
[0022] Initially, the float 13 floats on the liquid surface, so that the water inlet gap 14 is located at the liquid surface, and the filter screen 15 intercepts the impurities on the liquid surface. The water pumping mechanism 20 is in standby state, the pump 21 is not started, and all the second valves 25, the third valve 26, the blowdown valve 28 and the first valve 271 are closed. During operation, the first valve 271 and the blowdown valve 28 on the connecting pipeline 24 are opened, and the pump 21 is started. The liquid starts to flow, and the liquid is intercepted by the filter screen 15 after flowing through the water inlet gap 14 to eliminate the foam, and then flows into the telescopic sleeve 12, and then enters the water pumping pipeline 22 through the connecting pipeline 27, and is pumped by the pump 21 and discharged from the sewage treatment device through the blowdown valve 28 of the drainage pipeline 23. During the process, as the liquid level in the aeration chamber 101 rises or falls, the water inlet gap also rises or falls to be always located at the liquid surface.

However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
