Embodiment 1

[0036] Such as Figure 1 to Figure 2 As shown, a mud solid-liquid separator includes a filter press 1, the filter press 1 is provided with filter plates 2 parallel to each other and arranged in a linear array, and the outer surface of the filter plate 2 is provided with Groove 3, two adjacent filter plates 2 are periodically bonded using the relevant action principle of the existing box-type filter press, that is, the common driving components in the prior art are used to periodically push the corresponding filter plates 2 for mutual The action of bonding, the groove 3 between two adjacent filter plates 2 is periodically closed to form a filter chamber, and the outside of the groove 3 is covered with a filter cloth 4 for separating the solids in the mud from the water in the mud, The middle part of the filter plate 2 is provided with a mud channel 6 through which the normal direction penetrates. By means of this channel, the pipeline for pumping the mud pumps the mud between t...

Embodiment 2

[0046] Such as Figure 1 to Figure 2 As shown, on the basis that the basic technical solution of Example 1 remains unchanged, the filter plate 2 is set as a cavity structure, and the side wall 31 of the groove 3 is set as an elastic rubber material. Fill the cavity of the filter plate 2 with water, and use the elastic deformation ability of the side wall of the filter plate 2. The high-pressure water in the cavity pushes the side wall of the filter plate 2 outward, and further squeezes out the water in the mud cake. .

[0047] In order to realize the above-mentioned technical operation, the required equipment and its connection relationship are: the No. 4 pump 19 and the water tank 20 , and the No. 4 pump 19 pumps the liquid in the water tank 20 to the cavity in the filter plate 2 . In order to adjust the pumping flow, a No. 3 valve 21 connected in parallel with the No. 4 pump 19 is also provided between the filter press 1 and the water tank 20 .

[0048] The above-mentioned...

Abstract

The invention relates to a mud solid-liquid separator and a process, belonging to the technical field of sewage filtering equipment. The mud solid-liquid separator includes a filter press. A filter plate is installed inside the filter press. Grooves are arranged on the outer surface of the filter plate. Two adjacent filter plates are periodically attached to each other, and the grooves in between are periodically closed to form a filter plate. The outside of the groove is covered with filter cloth, and there is a spring between the groove and the filter cloth; the process includes primary filtration, adding conditioner, pressure filtration and recovery, etc. The present invention uses a spring to eject the mud cake on the outside of the filter cloth. The spring not only changes the continuous curved surface of the filter cloth by its jacking action, so that the mud cake cannot be effectively attached, but also the instantaneous pushing effect of the spring force can effectively bounce the mud cake. From the beginning, the inertia is used to separate from the filter cloth, avoiding the adhesion of the sticky mud cake, reducing the frequent cleaning of the equipment, and greatly improving the continuity of production.

Description

technical field [0001] The invention relates to the technical field of sewage filtration, in particular to a mud solid-liquid separator and a process. Background technique [0002] At present, in the construction of mud retaining foundation projects (such as bored piles, underground diaphragm walls, mud-water balance shields and pile foundation construction, etc.), a large amount of waste mud is inevitably produced. Waste mud is a semi-colloidal suspension, which cannot be discharged directly, and it is difficult to condense and settle naturally in a short period of time. If it is not treated in time, the discharged mud will not only affect the construction process, but will also cause secondary public hazards such as environmental pollution and water pollution. [0003] The pollution of mud to the environment is mainly manifested as: [0004] 1. The waste mud is difficult to degrade in the natural state, which will cause soil compaction in the surrounding areas, land salin...
