Description

Technical Field

[0001] The utility model relates to a pumping station for sewage treatment, in particular to a reinforced all-plastic pumping station. Background Art

[0002] At present, the pumping station is an important part of the urban sewage treatment pipe network. Its structure includes a tank body, a tank opening at the top of the tank body, a tank cover for opening and closing the tank opening, and a crushing grille machine and a sewage lift pump in the tank body, etc. Among them, the crushing grille machine has a large weight. It is installed on the tank wall of the tank body by an independent suspension type, and there will be a single-point stress situation on the tank wall at this place. The outer shapes of the existing tank bodies are smooth cylindrical or rectangular, and the usage height is usually relatively high. Although some reinforcing ribs are designed on the outer surface of the tank body, these reinforcing ribs are mainly for the reinforcement of the outside of the tank body, while the single-point stress occurs inside the tank body. Especially, even with the addition of the external reinforcing ribs, due to the smooth geometric shape of the tank body, it is very difficult to provide stronger supporting force for the single-point stress position. Coupled with the vibration of the crushing grille machine during operation, after long-term use, local collapse and deformation of the tank wall at this place often occur, thus affecting the sealing performance of the tank body. At the same time, the weight of the sewage lift pump is also very large, and it is mainly installed in the tank body by a hoisting method. Since there is no guidance during the loading process, the sewage lift pump in the hoisting state lacks manual assistance in the tank body, resulting in phenomena such as free rotation and unstable center of gravity, so it is very difficult to accurately place it at the installation position in the tank body, bringing great inconvenience to the installation. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a reinforced all-plastic pumping station that can enhance the structural strength of the tank body and improve the accuracy of the installation position of the sewage lift pump in the tank body.

[0004] The technical problem of the utility model is realized through the following technical solutions:

[0005] A reinforced all-plastic pumping station includes a tank body, a tank opening at the top of the tank body, a tank cover for opening and closing the tank opening, and a crushing grille machine and a sewage lift pump in the tank body. A reinforcing frame is arranged in the tank body. The reinforcing frame is an integral frame structure jointly composed of a top reinforcing ring attached to the inner surface of the top of the tank body, a middle reinforcing ring attached to the inner surface of the middle of the tank body, a bottom reinforcing ring attached to the inner surface of the bottom of the tank body, and reinforcing rods connecting the top reinforcing ring, the middle reinforcing ring and the bottom reinforcing ring at the same time. The sewage lift pump is installed in the tank body through the guidance of the reinforcing frame. The crushing grille machine is installed on the reinforcing frame.

[0006] A top cross bar is arranged in the top reinforcing ring. A plurality of guide rods that are parallel to each other and vertically extend into the tank body are arranged on the top cross bar. The sewage lift pump is installed in the tank body along the guidance of the plurality of guide rods.

[0007] A middle cross bar is provided inside the middle reinforcement ring. A U-shaped frame is connected below the middle cross bar, and the crushing grille machine is installed inside the U-shaped frame.

[0008] A plurality of positioning lifting rings are provided on the top reinforcement ring. The plurality of positioning lifting rings are fitted into a plurality of positioning grooves on the top of the tank body, and form the positioning installation of the reinforcement frame inside the tank body.

[0009] The positioning lifting rings are connected between the top reinforcement ring and the reinforcement rod.

[0010] A guiding ring is provided on the reinforcement rod. The guiding ring is opposite to the outlet on the outer surface of the tank body. The sewage lifting pump has a pipe for outward output, and the pipe passes through the guiding ring and extends out of the outlet.

[0011] An internal maintenance platform is provided above the middle reinforcement ring.

[0012] The internal maintenance platform is a circular grid platform with the same outer diameter as the middle reinforcement ring.

[0013] The outer circumference of the internal maintenance platform is fixed to the reinforcement rod, and a middle hole is provided in the middle of the internal maintenance platform.

[0014] Compared with the prior art, the utility model mainly has a reinforcement frame inside the tank body. The reinforcement frame is an integral frame structure jointly composed of a top reinforcement ring attached to the inner surface of the top of the tank body, a middle reinforcement ring attached to the inner surface of the middle of the tank body, a bottom reinforcement ring attached to the inner surface of the bottom of the tank body, and reinforcement rods connecting the top reinforcement ring, the middle reinforcement ring and the bottom reinforcement ring at the same time. In this way, the internal support of the tank body can be formed through the internal reinforcement frame, so that sufficient structural strength can be provided even when the outer shape of the tank body is a smooth cylindrical or rectangular shape. At the same time, the crushing grille machine with a certain weight is no longer installed independently and suspended on the tank wall of the tank body, but directly installed on the stronger reinforcement frame. Therefore, the situation of single-point stress will not occur on the tank wall of the tank body. Even if the crushing grille machine vibrates during operation, it is only borne within the entire reinforcement frame, avoiding local collapse and deformation of the tank wall and affecting the sealing performance of the tank body. In addition, a top cross bar is provided inside the top reinforcement ring, and a plurality of guide rods parallel to each other and vertically extending into the tank body are provided on the top cross bar. Then, the sewage lifting pump installed into the tank body by hoisting can be guided and installed along the plurality of guide rods, so that phenomena such as free rotation and unstable center of gravity will not occur even in the absence of manual assistance inside the tank body. Therefore, it can be accurately placed at the installation position inside the tank body and brings great convenience to the installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] A reinforced all-plastic pumping station, as Figure 1 , Figure 2 shown, is mainly used for urban sewage treatment and is an important part of the urban sewage treatment pipe network. Its structure includes a tank body 1, a tank opening at the top of the tank body, a tank cover 2 for opening and closing the tank opening, and a crushing grille machine 5 and a sewage lift pump 4 in the tank body, etc.

[0029] The described tank body 1 and tank cover 2 are all fully plastic components manufactured by rotational molding. The outer shape of the tank body 1 is cylindrical, and a reinforcing frame 3 made of stainless steel is provided inside the tank body 1.

[0030] The described reinforcing frame 3 is an integral frame structure jointly composed of a top reinforcing ring 31 attached to the inner surface of the top of the tank body, a middle reinforcing ring 32 attached to the inner surface of the middle of the tank body, a bottom reinforcing ring 33 attached to the inner surface of the bottom of the tank body, and a reinforcing rod 34 connecting the top reinforcing ring 31, middle reinforcing ring 32, and bottom reinforcing ring 33 at the same time. The top reinforcing ring 31, middle reinforcing ring 32, and bottom reinforcing ring 33 are all circles made of stainless steel. The reinforcing rod 34 is a straight rod made of stainless steel, and the number of the reinforcing rods 34 is mainly determined according to the height and outer diameter of the tank body 1, and is designed to be circumferentially surrounded by welding.

[0031] A plurality of positioning lifting rings 36 are provided on the top reinforcing ring 31. In this embodiment, four circumferentially evenly distributed positioning lifting rings 36 are designed. After the reinforcing frame 3 is installed inside the tank body 1, the four positioning lifting rings can be directly assembled into a plurality of positioning grooves on the top of the tank body 1, so as to form the positioning installation of the reinforcing frame 3 inside the tank body 1. This installation method can ensure that the reinforcing frame 3 can better fit on the inner surface of the tank body 1 without displacement, so as to provide better internal support for the tank body, and is also for the convenience of the subsequent sewage pump 4 to be guided for accurate installation, and is also convenient for the overall lifting of the reinforcing frame 3.

[0032] Moreover, the positioning lifting rings 36 are usually connected between the top reinforcing ring 31 and the reinforcing rod 34 because the structural strength at this connection is relatively high and can provide the maximum bearing capacity during the lifting of the reinforcing frame 3.

[0033] A middle cross bar 39 is provided inside the middle reinforcing ring 32. The middle cross bar is a stainless steel straight rod with both ends fixed to the middle reinforcing ring 32. A U-shaped frame 38 is connected below the middle cross bar 39, and a fixed crushing grille machine 5 is provided inside the U-shaped frame.

[0034] In this way, through the internal support of the reinforcing frame 3 for the inside of the tank body 1, when the outer shape of the tank body is a smooth cylinder or rectangle, sufficient structural strength can also be provided; moreover, the crushing grille machine 5 with a certain weight is no longer independently suspended and installed on the tank wall of the tank body 1, but can be directly installed on the stronger reinforcing frame 3 through the U-shaped frame 38 and the middle cross bar 39; therefore, the situation of single-point force on the tank wall of the tank body 1 will not occur. Even if the crushing grille machine 5 vibrates during operation, it is only borne within the entire reinforcing frame 3, avoiding local collapse and deformation of the tank wall and affecting the sealing performance of the tank body 1.

[0035] A top cross bar 37 is further provided inside the described top reinforcement ring 31. The top cross bar is a stainless steel straight bar with both ends fixed to the top reinforcement ring 31 respectively. A plurality of guide rods 35 which are parallel to each other and perpendicularly extend into the tank body 1 are provided on the top cross bar 37. For example, if four guide rods are designed in this embodiment, the sewage lift pump 4 installed in the tank body 1 by means of hoisting can be guided and installed along the plurality of guide rods 35, so that phenomena such as free rotation and unstable center of gravity will not occur even without manual assistance inside the tank body 1. Therefore, it can be accurately placed at the installation position inside the tank body 1 and brings great convenience to the installation.

[0036] An internal maintenance platform 6 is provided above the described middle reinforcement ring 32. The internal maintenance platform is a circular grid platform with the same outer diameter as the middle reinforcement ring 32. The outer circumference of the internal maintenance platform 6 is fixed to the reinforcement rod 34. A middle hole 61 is provided in the middle of the internal maintenance platform 6, which can be passed through by the guide rod 35 and for the hoisting of the sewage lift pump 4.

[0037] A guide ring 7 is provided on one of the reinforcement rods 34, and its position is usually exactly opposite to the crushing grille machine 5. The guide ring 7 can be directly opposite to the outlet on the outer surface of the tank body 1. The sewage lift pump 4 has a pipe 41 that outputs outward. The pipe can accurately extend out of the outlet and install a flexible connection flange 43 through the guidance of passing through the guide ring 7. An opening and closing valve group 42 is also provided on the pipe 41, which is convenient for temporarily closing the pipe 41 when the sewage lift pump 4 is being maintained.

[0038] The above are only specific embodiments of the present invention. Those skilled in the art should understand that any structural design equivalent to this embodiment should be included within the protection scope of the present invention.
