Description

[Brief explanation of drawings]

FIGS. 1 and 2 are explanatory diagrams showing only essential parts for explaining the embodiment, with FIG. 1 being a plan view and FIG. 2 being a front view. Figure 3 is a vertical cross-sectional view along A-A in Figure 1 mainly showing only the pressure/vacuum filtration primary dehydration equipment, and the parts marked * are connected to the parts marked * in Figures 7 and 8. Show what you are doing. FIG. 4 is a vertical sectional view taken along line CC in FIG. 2, mainly showing only the pressure/vacuum filtration primary dehydration device. FIG. 5 is a left side view of FIG. 2 showing only the relationship between the fluid cylinder and the support arm. FIG. 6 is a longitudinal cross-sectional section taken along line BB in FIG. 2, showing only the relationship between the stopper and the support arm. Fig. 7 is a perspective view mainly showing only the installation state of the fountain nozzle and the air ejector as seen from the direction D-D in Fig. 2, and the parts marked with * are connected to the parts marked with * in Fig. 3. Show that. FIG. 8 is a central vertical cross-sectional view of a combination of a fountain nozzle and an air esector, and the part marked with * shows that it is connected to the part marked with * in Fig. 3.

Claims (1)

[Scope of utility model registration request] It is mounted between a drive roll and a support roll which are located horizontally and parallel to each other on the mount of the device, and is pulled and driven from the support roll towards the drive roll, with the upper side being the forward process and the lower side being the return process. A belt-shaped endless filter cloth that circulates as a process, a primary dewatering device provided in the forward process following the support roll on the filter cloth, a press roll dewatering device provided on the drive roll side, and a press roll dewatering device provided in the return process. The primary dewatering device mainly consists of a filter cloth cleaning device having a plurality of fountain nozzles for cleaning the filter cloth, and the primary dehydration device has an upper shell which is roughly equivalent to a box-shaped hollow shell divided into upper and lower halves by one plane. and a lower shell, forming a closed body that sandwiches the filter cloth in the middle at the center of its width, and the lower shell is fixed to the frame and is in contact with the lower surface of the filter cloth. The upper shell is located on the upper surface of the filter cloth opposite to the lower shell, and is supported by the pedestal via a pressure adjustment device for maintaining a required distance from the lower shell. At the same time, it engages with the lower end of a lowering means that applies a downward rolling force such as a pneumatic silicone whose upper end is connected to the frame, and furthermore, on the advancing exit side of the filter cloth, there is a suppression adjustment device for cake formation. In a continuous dewatering device having a partition section, sludge water is fed under pressure to the upper shell and filtered waste water is discharged from the lower shell, and a plurality of the fountain nozzles for washing the filter cloth are installed. For each, a plurality of air ejectors are provided by providing a tie user with an air chamber opening around the tip thereof, and the air chamber is connected to the air inlet pipe via an air intake pipe and a low-pressure intake pipe in which the air intake pipes are assembled. A drain pipe connected to the upper side of the lower shell to maintain the inside of the lower shell in a reduced pressure state, and further having a drain port at the bottom of the lower shell is provided with a main seal part forming a U-shaped conduit, The position of the top of the U-shaped pipe is lower than the height of the drain port, and the height difference is at a constant height that is greater than or equal to the rise in water level in the drain pipe caused by the reduced pressure in the lower shell. 1. A continuous automatic dehydration device having a pressure/vacuum filtration primary dehydration device, characterized in that:
