Description

Technical Field

[0001] The utility model relates to the technical field of underground sewage treatment equipment, in particular to a small underground sewage treatment equipment. Background Art

[0002] The buried sewage treatment equipment is a modular and efficient sewage biological treatment equipment. It is a sewage biological treatment system with biofilm as the main purification body. It gives full play to the characteristics of anaerobic biological filter, contact oxidation bed and other biofilm reactors, such as high biological density, strong pollution resistance, low power consumption, stable operation and convenient maintenance, which makes the system have a broad application prospect and promotion value.

[0003] The underground sewage treatment equipment is to dig a groove in the soil that is the same as the equipment, and then place the equipment in it, so as to avoid the equipment occupying the space above the ground. However, since the underground sewage treatment equipment is below the ground, if there are high buildings around it, the high buildings will produce earth pressure on the soil. Under the squeezing of the earth pressure, the underground sewage treatment equipment may be squeezed above the ground level, affecting the normal use function of the underground sewage treatment equipment, and may even cause the pipes connected to the underground sewage treatment equipment to break, increasing maintenance costs.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0023] The device's "front, back, left, right" viewing angles are Figure 1 The directions in the attached drawings are taken as reference.

[0024] like Figure 1-5 As shown, a small underground sewage treatment equipment includes a tank body 1. The top surface of the tank body 1 is provided with three connecting pipes 2. The connecting pipes 2 are reserved at the corresponding positions of the tank body 1 before the tank body 1 is processed, which can ensure the basic use function of the tank body 1. A feed pipe 3 is fixedly connected to the center of the upper left side of the tank body 1, and a lead-out pipe 4 is fixedly connected to the center of the lower right side of the tank body 1. The feed pipe 3 and the lead-out pipe 4 are both reserved and fixed and are an integral part of the tank body 1. Two ejection cavities 5 are provided around the inside of the tank body 1, and the upper sides of the inner walls of the multiple ejection cavities 5 are slidably connected. The top groove block 6 has an inner wall that is eccentrically arranged to ensure that there is enough space on the top groove block 6 to ensure the arrangement of the arc groove 8. The inner walls of the multiple top groove blocks 6 are all threadedly connected with movable screw rods 7. The upper ends of the multiple movable screw rods 7 pass through the upper sides of the corresponding inner walls of the ejection cavities 5 and extend to the top surface of the pool body 1. Three arc grooves 8 are provided on the opposite sides of the multiple top groove blocks 6. The inner walls of the multiple ejection cavities 5 are away from the top groove block 6 and are located on one side of the multiple three arc grooves 8. The inner walls of the multiple inclined openings 9 are provided with ejection devices with variable covering ranges.

[0025] The ejection device includes an inclined block 10 slidably connected to the inner wall of the inclined mouth 9, and a conical block 11 is fixedly connected to the side of the inclined block 10 close to the top groove block 6. The conical block 11 is a rectangular block with four corner blocks removed from one side, which can ensure that the ball 12 is in better contact with the arc groove 8 and avoid the problem of limitation between the arc groove 8. The ball 12 is rotatably connected to the side of the conical block 11 close to the top groove block 6. Limiting grooves 13 are provided on the upper and lower sides of the inner wall of the inclined mouth 9, and one side of the inner wall of the two limiting grooves 13 is provided with a limiting device with a variable covering range.

[0026] The limiting device includes three limiting springs 14 fixedly connected to one side of the inner wall of the limiting groove 13. The three limiting springs 14 are fixedly connected to the limiting block 15 at one end close to the top groove block 6. One side of the limiting block 15 is fixedly connected to the surface of the inclined block 10. The rotation of the movable screw rod 7 will drive the movement of the top groove block 6. The movement of the top groove block 6 will be squeezed by the arc surface of the arc groove 8, so that the conical block 11 on the ball 12 moves away from the top groove block 6. The movement of the conical block 11 will drive the inclined block 10 fixed thereon to move. The use of the inclined block 10 will be inserted into the soil layer buried in the pool body 1 to ensure the stability of the pool body 1 during use. The above structure ensures that the friction between the equipment and the soil layer is increased, thereby increasing the connection strength with the soil layer, avoiding the equipment being squeezed by the soil pressure. It may be squeezed above the ground plane, affecting the normal use function of the equipment, avoiding the problem of pipeline rupture connected to the equipment, and avoiding increased maintenance costs.

The surfaces of the operating blocks 16 and the pipe covers 17 are provided with protective grooves, which can ensure the firm effect during use and avoid the problem of operators' hands slipping during use. Through the setting of the operating blocks 16, the comfort of the operators in the equipment is guaranteed and the adaptability of the equipment is improved. Through the setting of the pipe covers 17, impurities in the environment can be prevented from entering the pool body 1 and causing pollution to the water quality.

[0028] like Figure 2-5 As shown, in some embodiments, vertical columns 18 are fixedly connected at the four corners of the top surface of the pool body 1, and rope rings 19 are fixedly connected at the upper ends of the four vertical columns 18. The rope rings 19 and the vertical columns 18 are welded to ensure the fixing effect. Multiple operating blocks 16 and three pipe covers 17 are circular block structures made of stainless steel. The arrangement of the vertical columns 18 and the rope rings 19 can ensure the convenience of transportation and lifting of the pool body 1 before installation. The material arrangement of the operating blocks 16 and the pipe covers 17 can ensure the corrosion resistance of the devices in the equipment and increase the service life of the devices in the equipment.
