Description

Technical Field

[0001] The utility model relates to the technical field of sewage environmental protection, in particular to a protection device for the sewage discharge port of a paper machine. Background Technique

[0002] There is no safety protection device for the sewage discharge port of the paper machine. Generally, a grid plate is used to cover the sewage discharge port of the paper machine for protection, which has the risks of personnel falling and tripping and potential equipment safety hazards. At present, a traditional welded integrated guardrail is used to cover the periphery of the sewage discharge port of the paper machine, which can play a certain role in preventing personnel from falling. However, the traditional welded integrated guardrail is not convenient to remove. When the equipment inside the sewage discharge port of the paper machine needs to be repaired later, it is impossible to easily remove the traditional welded integrated guardrail. Moreover, the gaps around the welded integrated guardrail are relatively large, and foreign objects can easily pass through the gaps around the guardrail and directly fall into the sewage discharge port of the paper machine, causing blockage, so improvement is needed. Therefore, we propose a protection device for the sewage discharge port of the paper machine. Content of the Utility Model

[0003] The purpose of the utility model is to provide a protection device for the sewage discharge port of the paper machine, which solves the problems put forward in the background technique.

[0004] To achieve the above purpose, the utility model provides the following technical scheme: a protection device for the sewage discharge port of the paper machine, including four columns, a frame body that defines the four columns, and a curtain structure. The number of the frame bodies is two. The frame body includes an X-shaped frame, a square frame fixed at the four end points of the X-shaped frame, and a cross beam connecting adjacent two square frames. The curtain structure includes a net curtain and a counterweight ball fixed at the bottom end of the net curtain.

[0005] As a preferred implementation mode of the technical scheme of the present application, through holes are opened on the surface of the square frame, screws are inlaid inside the through holes, and threaded holes for the screws to cooperate are opened on the surface of the column.

[0006] As a preferred implementation mode of the technical scheme of the present application, a fixing strip is fixedly arranged at the top of the net curtain, and the fixing strip is fixed on the cross beam surface of the top layer frame body.

[0007] As a preferred implementation mode of the technical scheme of the present application, the net curtain is a nylon net, the number of the counterweight balls is several, and the distance between adjacent two counterweight balls is 20 cm.

[0008] As a preferred implementation mode of the technical scheme of the present application, the number of the curtain structures is four, and the four curtain structures are distributed on the four vertical sides of the protection device for the sewage discharge port of the paper machine.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] 1. The technical solution of this application forms a protective fence through the assembly of the frame body and the columns, which can prevent people from falling into the sewage outlet, avoid tripping accidents, and protect the equipment from being damaged by collision. The frame body uses an X-shaped frame as the central support, and with the cross beams, it can greatly improve the structural stability after the assembly of the frame body and the columns. It not only has the detachable property but also takes into account the impact resistance and stability.

[0011] 2. The technical solution of this application installs a curtain structure on the four cross beams to block foreign objects from directly falling into the sewage outlet to avoid blockage, and at the same time, the curtain structure does not affect the real-time observation of the sewage outlet.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0018] Embodiment 1, as Figures 1 - 3 shown, the present utility model provides a technical solution: a protective device for a paper machine wastewater sewage outlet, including four columns 1, a frame body 2 that defines the four columns 1, and a curtain structure 3. The number of the frame bodies 2 is two. The frame body 2 includes an X-shaped frame 201, square boxes 202 fixed at the four end points of the X-shaped frame 201, and cross beams 203 connecting adjacent two square boxes 202. The curtain structure 3 includes a mesh curtain 302 and a counterweight ball 301 fixed at the bottom end of the mesh curtain 302.

[0019] In a specific embodiment of the present utility model, the horizontal cross-section of the upright column 1 is consistent with the shape of the inner cavity of the square frame 202. The two frame bodies 2 are sequentially fitted with the four upright columns 1 in an inlaid manner. The two frame bodies 2 are arranged vertically. The square frame 202 is fixedly assembled with the upright column 1 by screws. The distances from the two frame bodies 2 to the ends of the upright column 1 are both set to 10 cm. The upright column 1, the square frame 202, and the cross beam 203 all adopt an aluminum alloy hollow column structure. The square frame 202 is a solid aluminum alloy frame sleeve. The protection device covers the outside of the paper machine wastewater drain outlet. The curtain structure 3 is assembled on the cross beam 203 of the upper layer frame body 2 to prevent foreign objects from falling into the paper machine wastewater drain outlet. The counterweight ball 301 is used to keep the mesh curtain 302 in a vertically flattened state.

[0020] In the preferred technical solution, through holes are formed on the surface of the square frame 202, and screws are inlaid inside the through holes. Threaded holes for mating with the screws are formed on the surface of the upright column 1. The screws and the threaded holes are used to realize the detachable assembly of the square frame 202 and the upright column 1.

[0021] In the preferred technical solution, a fixing strip is fixedly arranged at the top of the mesh curtain 302, and the fixing strip is fixed on the surface of the cross beam 203 of the top layer frame body 2. The mesh curtain 302 is a nylon mesh. Nylon mesh is one of the commonly used materials for making anti-falling nets. It has the advantages of high strength, low density, good resilience, good anti-fatigue performance, good thermal stability, wear resistance, etc., and is suitable for preventing foreign objects from entering and falling into the paper machine wastewater drain outlet. The number of counterweight balls 301 is several, and the distance between two adjacent counterweight balls 301 is 20 cm. The counterweight ball 301 is used to keep the mesh curtain 302 in a vertically flattened state.

[0022] In the preferred technical solution, the number of the curtain structures 3 is four, and the four curtain structures 3 are distributed on the four vertical sides of the protection device of the paper machine wastewater drain outlet. The four sides of the protection device of the paper machine wastewater drain outlet are all provided with the curtain structures 3 to improve the overall protection.

[0023] In summary, based on the problem that the existing paper machine wastewater drain outlet lacks protection, this embodiment proposes an assembled guardrail structure. By using the support structure of the X-shaped frame and the cross beam, the structural stability of the assembled guardrail is improved. At the same time, curtain structures 3 are arranged on the four vertical sides of the protection device of the paper machine wastewater drain outlet to prevent foreign objects from entering and falling into the paper machine wastewater drain outlet, and at the same time, it does not affect the real-time observation of the situation of the paper machine wastewater drain outlet, prevent people from falling into the drain outlet, avoid tripping accidents, and protect the equipment from being damaged by collision.
