Description

Technical Field

[0001] The utility model relates to the technical field of concrete shield segments, in particular to a steaming cellar for concrete shield segments. Background Art

[0002] During the production of concrete shield segments, a steaming kiln is required for their maintenance. After searching, it was found that the existing technology, such as the Chinese patent (authorization number: CN216682694U), provides an environmentally friendly, membrane-free shield segment steaming kiln. The top membrane, water collection trough and water collection pipe cooperate with each other to collect clean condensed water into the second recovery tank, and the condensed water mixed with oil is collected into the first recovery tank through the V-shaped ground setting, which facilitates the recycling of condensed water and saves costs.

[0003] The grate on the first recovery tank can filter out the debris in the sewage to ensure that the filtered water can be recycled. However, the debris gathers on the grate, and the grate is flat. When there are too many debris on the grate, it will not only cause the grate to be blocked, but also be very troublesome to clean the debris. It is necessary to move along the grate a little bit to clean the debris, which is time-consuming and labor-intensive. Therefore, improvements are needed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a steaming cellar for concrete shield segments, which solves the problems mentioned in the background art.

[0005] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] A concrete shield segment steaming cellar comprises two opposing walls connected to a roof panel with multiple steam nozzles installed on the walls. The two walls and the roof panel cooperate to form a steaming space, with automatic doors at the entrance and exit. The floor of the steaming space slopes downward from the two walls toward the center, with a recovery trough located at its lowest point. A grate is fixed to the trough's opening.

[0007] The most important difference between the present invention and the prior art is that a device for flushing debris on the grate is provided at the rear end of the recovery tank.

[0008] In order to more conveniently clean the debris on the grate, the grate is inclined downward from the rear end to the front end.

[0009] Specifically in the present invention, the device for flushing the grate includes a water pump installed on the ground in the steaming space, the free end of the water pump suction pipe is located below the grate and is connected to the recovery tank, and the outlet pipe is connected to the flushing structure, the flushing structure includes a water spray pipe, the water spray pipe is connected to the water outlet pipe of the water pump, and a plurality of spray holes arranged at equal intervals are provided on the side of the water spray pipe close to the recovery tank. The water spray pipe is an inverted U-shaped pipe, the top rod of the water spray pipe is connected to the water outlet pipe of the water pump, the lower ends of the two side rods of the water spray pipe are fixed on the ground in the steaming space, and the spray holes are provided on the side of the top rod close to the recovery tank.

[0010] Compared with the prior art, the utility model has the following beneficial effects: the water pump sprays the water recovered in the recovery tank onto the grate, flushes the debris on the grate forward, and gathers the debris at the front end of the grate, which is easy to clean, has a simple structure and is highly practical.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0018] Ruru Figure 1As shown, the utility model provides a concrete shield segment steaming cellar, comprising two oppositely arranged walls 1, the upper ends of the two walls 1 are connected to a top plate 2, a plurality of steam nozzles 3 are provided on the wall 1, the two walls 1 and the top plate 2 cooperate with each other to form a steaming space, and an automatic door is provided at the inlet and outlet of the steaming space. Here, a water pump 6 is located at the steaming outlet, and the outlet pipe of the water pump 6 can pass through the automatic door. The automatic door can also be designed in a shape that does not affect the normal use of the outlet pipe of the water pump 6. For example, a U-shaped notch is designed at the lower end of the automatic door, and the outlet pipe of the water pump 6 extends into the steaming space through the notch. The ground in the steaming space is downwardly inclined from the two side walls 1 to the middle position, and a recovery trough 4 is provided at the lowest point. A grate 5 is fixed at the notch of the recovery trough 4. The above structures are all prior art. The steam sprayed by the steam nozzle 3 condenses into water droplets when it is cold and flows into the recovery trough 4 for recovery. For more specific working principles, please refer to Chinese patent (authorization number: CN216682694U), which will not be repeated in this utility model.

[0019] like Figure 1-3 As shown, the main difference between the present invention and the prior art is that a device for flushing debris on the grate 5 is provided at the rear end of the recovery tank 4 .

[0020] like Figure 3 As shown, in order to more conveniently clean the debris on the grate 5, the grate 5 is tilted downward from the rear end to the front end.

[0021] like Figure 4-5 As shown, in the present invention, specifically, the device for flushing the grate 5 includes a water pump 6 installed on the ground in the steaming space, the water pump 6 is powered by an external power supply, the free end of the water pump 6 suction pipe is located below the grate 5 and is connected to the recovery tank 4, and the outlet pipe is connected to a flushing structure, the flushing structure includes a water spray pipe 7, the water spray pipe 7 is connected to the outlet pipe of the water pump 6, and a plurality of spray holes 8 arranged at equal intervals are provided on the side of the water spray pipe 7 close to the recovery tank 4. The spray holes 8 can be inclined, and the inclination is the same as the inclination of the grate 5. The water spray pipe 7 is an inverted U-shaped pipe, and the top rod of the water spray pipe 7 is connected to the outlet pipe of the water pump 6. The lower ends of the two side rods of the water spray pipe 7 are fixed on the ground in the steaming space, and the spray holes 8 are provided on the side of the top rod close to the recovery tank 4.

[0022] When in use, the water pump 6 is connected to an external power supply, and the water in the recovery tank 4 is pumped into the water pump 6 through the water pump pipe, and then enters the water spray pipe 7 through the water outlet pipe, and is sprayed out through the spray hole 8 to wash the upper surface of the grate 5, thereby washing the debris on the grate 5 to the front end, and the debris gathers at the front end of the grate 5, which is easy to clean.

[0023] Compared with the prior art, the utility model has the following beneficial effects: the water pump 6 sprays the water recovered in the recovery tank 4 onto the grate 5, flushes the debris on the grate 5 forward, and makes the debris gather at the front end of the grate 5, which is easy to clean, has a simple structure and high practicality.
