Embodiment Construction
[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0030] As described in the background art, there are deficiencies in the prior art, in order to solve the above technical problems, the present application proposes a high-efficiency plate and frame filter press
[0031] In a typical embodiment of the present application, such as Figure 1-7 As shown, a high-efficiency plate and frame filter press includes a frame body, and the frame body includes a thrust plate 1, a pressing plate 2,...

The invention relates to the field of plate-and-frame filter presses, and discloses an efficient plate-and-frame filter press and a sewage comprehensive treatment system.When a telescopic air cylinder drives a rotary base to close a discharging channel, a pull rope pulls a branch rope, a chassis is indirectly made to ascend, a crushing spring is compressed, the crushing spring is made to be in a force storage state, and after solid-liquid separation, the crushing spring is separated from the discharging channel. The telescopic air cylinder drives the rotary base to open the discharging channel, at the moment, the pull rope drives the branch rope to rebound, then the base plate and the crushing spring are restored to the initial state, the crushing spring in the force storage state drives the base plate to stretch, the whole dehydrated filter cake is crushed, and discharging of the filter cake is facilitated; by arranging the crushing assembly, the discharging channel is prevented from being adsorbed on the inner wall of the filter pressing assembly under high-pressure filter pressing to cause difficult discharging, by arranging the linkage assembly, the discharging channel and the crushing assembly are operated in an associated mode, intelligence and automation of the filter press are achieved, and compared with a traditional step-by-step discharging mode, more time and labor are saved, and the filter pressing efficiency can be obviously improved under the condition that the filter pressing demand quantity is large.
Description
technical field [0001] The invention relates to the field of plate and frame filter presses, in particular to a high-efficiency plate and frame filter press and a comprehensive sewage treatment system. Background technique [0002] The plate and frame filter press is the first machine used in chemical dehydration. Although the plate and frame filter press is generally operated intermittently, the investment in infrastructure equipment is large, and the filtration capacity is also low, due to its large filtration driving force, high solid content of the filter cake, clear filtrate, high solid recovery rate, and conditioning drugs Due to the advantages of less consumption, it is still widely used in some small sewage plants. [0003] When the traditional plate and frame filter press is unloading, it is necessary to gradually separate each filter frame. Although the patent document with the publication number CN109260790B proposes a linkage type plate and frame filter press to...
