The vacuum box is of a cubic box structure, a water outlet is formed in the side face of the vacuum box, at least 3 supporting plate strips are fixed on the upper surface of the vacuum box in parallel, and a vacuum negative pressure meter is installed on the opposite face of the water outlet.
The supporting plate strips are made of ceramic materials.
Vacuum tank inside wall mid-mounting has a level gauge, the input electric connection of level gauge output and controller, controller output and suction pump input electric connection.
The utility model discloses has following effect: the technical scheme mainly utilizes a vacuum dehydration mode to realize the rapid dehydration process of the fiber board blank. The dewatering area formed by a plurality of vacuum boxes on the conveyor support can quickly remove most of moisture contained in the upper plate blank due to the existence of negative pressure; the drainage system composed of the liquid level meter, the controller and the water suction pump can ensure the net drainage amount in the vacuum tank so as to prevent the net drainage amount from immersing into the vacuum pump and ensure the normal and stable operation of the vacuum pump.

Description of the drawings: 1. the device comprises a conveyor support, 2 parts of a mesh belt, 3 parts of a vacuum box, 3-1 parts of a water outlet, 3-2 parts of a supporting plate strip, 3-3 parts of a vacuum negative pressure meter, 4 parts of a drainage pipeline, 5 parts of a drainage collecting pipeline, 6 parts of a vacuum tank, 6-1 parts of a liquid level meter, 7 parts of a vacuum pump, 8 parts of a water suction pump.
Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.
The technical scheme combines the detailed description of the embodiments with the drawings. As shown in fig. 1, at least 5 vacuum boxes 3 are arranged in parallel along the conveying direction and fixed in the middle of a conveyor support 1, the upper surfaces of the vacuum boxes 3 are flush and contact with a mesh belt 2, one end of each drainage pipeline 4 is connected to the corresponding vacuum box 3, the other end of each drainage pipeline is connected with a drainage collection pipeline 5, the drainage collection pipeline 5 is connected to the side surface of the vacuum tank 6 near the bottom, the upper part of the vacuum tank 6 is connected with a vacuum pump 7 through a pipeline, and a water suction pump 8 is connected to the side surface of the vacuum tank 6 near the bottom through a pipeline.
The middle part of the inner side wall of the vacuum tank 6 is provided with a liquid level meter 6-1, the output end of the liquid level meter 6-1 is electrically connected with the input end of a controller, and the output end of the controller is electrically connected with the input end of the water suction pump 8. The control system can control the opening and closing of the water pump 8 according to the liquid level in the tank so as to achieve the aim of controlling the dynamic balance of the liquid level in the tank.
As shown in figure 2, the vacuum box 3 is a cubic box structure and is provided with a water outlet 3-1 on the side surface, at least 3 supporting plate strips 3-2 are fixed on the upper surface of the vacuum box 3 in parallel, and a vacuum negative pressure meter 3-3 is arranged on the opposite surface of the water outlet. The vacuum negative pressure gauge 3-3 can facilitate the staff to monitor the negative pressure condition in each vacuum box 3 at any time.
The supporting plate strips 3-2 play a role of reinforcing the vacuum box 3 on one hand and a role of supporting the mesh belt 2 on the other hand. The supporting plate strips 3-2 are made of ceramic materials, are wear-resistant and smooth, and can effectively reduce friction with the mesh belt 2.
The mat formed by paving is conveyed to the on-line dehydration system of the mat by the fourdrinier forming machine. The vacuum pump 7 in the system is always in operation. As the mat moves downstream with the belt 2, it passes through the dewatering zone consisting of the vacuum boxes 3. At this time, the mat is forcibly subjected to the dewatering operation by the negative pressure of each vacuum box 3. The removed net drainage is collected in the drainage collection pipe 5 through each vacuum box 3 and the corresponding drainage pipe 4, and finally enters the vacuum tank 6.
The more the net drainage in the vacuum tank 6 is accumulated, when the liquid level reaches the height of the liquid level meter 6-1, the liquid level meter 6-1 sends an electric signal to the controller, the water suction pump 8 is immediately started under the action of the controller to force the net drainage in the tank to be discharged along the pipeline, and the net drainage quantity in the tank is reduced, so that the net drainage is ensured not to be immersed into the vacuum pump 7, and the normal operation of the vacuum pump 7 is ensured.
Compared with a self-weight dehydration mode, the online dehydration system for the plate blank has higher dehydration efficiency. And by adopting the devices of the liquid level meter 6-1, the controller, the water pump 8 and the vacuum tank 6, the water under the net can be effectively prevented from soaking into the vacuum pump, and the normal and stable operation of the vacuum pump is ensured.
In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected, and may communicate between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
