Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment pool with a variable volume. Background Art

[0002] In modern industrial and agricultural production, a large amount of water is used, and a large amount of sewage will be generated in the process of industrial and agricultural water use. In order to improve environmental protection, sewage cannot be discharged at will. Therefore, sewage treatment plays a very important role in the development of modern society. In the sewage treatment process, such sewage treatment pools need to collect sewage. With the development of science and technology, the functions of sewage pools are also constantly increasing, so that they can better meet the needs of use.

[0003] In view of this, Chinese Patent No. CN2412897Y proposes a sewage treatment tank with variable volume. The sewage treatment tank of the utility model has the advantages of simple structure and easy control, and is suitable for use in communities or similar occasions. However, during the use of the sewage treatment tank, the volume of the sewage tank cannot be actually changed, and the volume cannot be changed in the treatment of sewage of different capacities, so that when the capacity is small, the liquid level is low, and the height difference between the sedimentation layer and the clear water layer is small, and sedimentation and treatment are very inconvenient. Therefore, a sewage treatment tank structure with variable volume is needed. Utility Model Content

[0004] In order to solve the above problems, the purpose of the utility model is to provide a sewage treatment tank with a variable volume to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model proposes a sewage treatment pool with variable volume, including a sewage pool body, and a volume adjustment mechanism is arranged at the upper end of the sewage pool body;

[0006] The volume adjustment mechanism includes first limit grooves opened on both sides of the top of the sewage pool body, and a second limit groove is opened on the other side of the top of the sewage pool body. A partition is slidably provided on the inner wall of the sewage pool body, and the outer walls at both ends of the partition are respectively slidably connected to the inner walls of the two first limit grooves. A clamping rail is fixedly provided at the middle position of the top of the partition, and first sliders are slidably provided at both ends of the outer wall of the clamping rail, and second sliders are slidably provided at both ends of the inner wall of the second limit groove. A first connecting rod is rotatably provided between the two first sliders and the two second sliders, and a first connecting shaft is fixedly provided on both sides of the top of the first connecting rod, and a first hydraulic rod is rotatably provided between the outer walls of the two first connecting shafts.

[0007] In one example, a rubber strip is fixedly provided at the edge of one side of the partition, and connecting plates are fixedly provided at both ends of the inner wall of the rubber strip.

[0008] In one example, a second connecting rod is rotatably provided between the four connecting plates, and a second connecting shaft is fixedly provided on one side of two of the second connecting rods.

[0009] In one example, a second hydraulic rod is rotatably provided between the two second connecting shafts, and the outer wall of the rubber strip is in contact with the inner wall of the sewage tank body.

[0010] In one example, a water inlet pipe is inserted into the upper end of one side of the sewage pool body.

[0011] In one example, a drain pipe is inserted into the lower end of the other side of the sewage pool body, and a sealing valve is rotatably provided on one side of the drain pipe.

[0012] The variable volume sewage treatment tank proposed by the utility model can bring the following beneficial effects:

[0013] 1. This variable-volume sewage treatment pool starts the first hydraulic rod to extend and retract according to the amount of sewage, and then folds and retracts the first connecting rod, thereby changing the extension length of the first connecting rod, so that the partition slides in the first limiting groove, thereby changing the volume size inside the sewage pool body, making it convenient to settle and treat different amounts of sewage, and improving the practicability of the device.

[0014] 2. In this variable-volume sewage treatment tank, after the volume is changed, the second hydraulic rod is started to rotate and extend on the second connecting shaft, so that the second connecting rod is folded and extended, so that the rubber strip is squeezed through the connecting plate. While the rubber strip is stretched, the squeezing of the inner wall of the sewage tank body is not increased, so that the contact gap between the partition and the sewage tank is blocked, thereby improving the sealing of the device.

DETAILED DESCRIPTION

[0021] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in the form of examples in conjunction with the accompanying drawings.

[0022] The examples are as follows:

[0023] The utility model provides Figure 1-4 A variable-volume sewage treatment tank shown includes a sewage tank body 1, and a volume adjustment mechanism is provided at the upper end of the sewage tank body 1;

[0024] The volume adjustment mechanism includes a first limiting groove 2 provided on both sides of the top of the sewage pool body 1, a second limiting groove 3 provided on the other side of the top of the sewage pool body 1, a partition 4 slidably provided on the inner wall of the sewage pool body 1, and the outer walls at both ends of the partition 4 are respectively slidably connected to the inner walls of the two first limiting grooves 2, a clamping rail 5 is fixedly provided at the middle position of the top of the partition 4, first sliders 6 are slidably provided at both ends of the outer wall of the clamping rail 5, and second sliders 7 are slidably provided at both ends of the inner wall of the second limiting groove 3, a first connecting rod 8 is rotatably provided between the two first sliders 6 and the two second sliders 7, first connecting shafts 9 are fixedly provided on both sides of the top of the first connecting rod 8, a first hydraulic rod 10 is rotatably provided between the outer walls of the two first connecting shafts 9, and the first slider 6 slides on the clamping rail 5, and the second slider 7 slides in the second limiting groove 3, so that the first connecting rod 8 does not generate torque when folding and retracting, and can drive the partition 4 to move back and forth;

[0025] Furthermore, a rubber strip 11 is fixedly provided at the edge of one side of the partition plate 4 , and connecting plates 12 are fixedly provided at both ends of the inner wall of the rubber strip 11 .

[0026] Second connecting rods 13 are rotatably disposed between the four connecting plates 12 , and second connecting shafts 14 are fixedly disposed on one side of two second connecting rods 13 .

[0027] A second hydraulic rod 15 is rotatably provided between the two second connecting shafts 14, and the outer wall of the rubber strip 11 contacts the inner wall of the sewage pool body 1. When the second connecting rod 13 stretches and pulls the rubber strip 11 to extend, it also generates an outward pushing force on the rubber strip 11, so that it can fully contact and squeeze the inner wall of the sewage pool body 1, thereby achieving sealing at the gap between the partition plate 4 and the inner wall of the sewage pool body 1.

[0028] Furthermore, a water inlet pipe 16 is inserted into the upper end of one side of the sewage tank body 1.

[0029] A drain pipe 17 is inserted at the lower end of the other side of the sewage pool body 1. A sealing valve is rotatably provided on one side of the drain pipe 17, and sewage is introduced through the water inlet pipe 16. At this time, the drain pipe 17 is sealed by the sealing valve. After sedimentation treatment, the sealing valve is opened to discharge from the drain pipe 17.

[0030] Working principle: When using the variable-volume sewage treatment tank in the present design, sewage needs to be discharged into the tank through the water inlet pipe 16 first, so that the sewage is allowed to settle in the sewage tank body 1. The first hydraulic rod 10 is activated according to the amount of sewage to make it extend and retract, and then the first connecting rod 8 is folded and retracted, thereby changing the extension length of the first connecting rod 8, so that the partition 4 slides in the first limiting groove 2, thereby changing the volume size inside the sewage tank body 1. During the folding process of the first connecting rod 8, it rotates on the first slider 6 and the second slider 7, and the first hydraulic rod 10 also rotates on the first connecting shaft 9, so that it does not generate torque, thereby improving the practicability of the device. After the volume changes, the second hydraulic rod 15 is activated to rotate and retract on the second connecting shaft 14, so that the second connecting rod 13 is folded and retracted, so that it squeezes the rubber strip 11 through the connecting plate 12. While the rubber strip 11 is stretched, the extrusion on the inner wall of the sewage tank body 1 is increased, so that the contact gap between the partition 4 and the sewage tank is blocked, thereby improving the sealing of the device.
