Sludge stock bin with rotary arch breaking mechanism

Abstract

The invention discloses a sludge stock bin with a rotary arch breaking mechanism. The sludge stock bin comprises a stock bin body, a spiral conveyor (3), an arch breaking mechanism and an arch breaking driving mechanism, wherein the arch breaking mechanism is arranged in the stock bin body, the arch breaking driving mechanism is connected with the arch breaking mechanism, and the spiral conveyor (3) is arranged at the lower part of the stock bin body; the stock bin body comprises an upper bin body (1) and a lower bin body (2), a separation board (4) is arranged between the upper bin body and the lower bin body, a strip-shaped blanking channel (5) is formed in the separation board, and the spiral conveyor is mounted in the lower bin body; and the arch breaking mechanism is the rotary arch breaking mechanism, the rotary arch breaking mechanism comprises scraping plates (7), a rotary assembly and a fixing rod (8), the scraping plates are connected onto the rotary assembly, and the fixing rod is fixed in the center of the separation board. According to the sludge stock bin with the rotary arch breaking mechanism, as direct friction is not caused among the scraping plates and the stock bin body in the rotating process of the scraping plates and the arch breaking can be carried out on the whole stock bin body, the stockpiling phenomenon is hard to occur, and a large amount of energy can be saved.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a sludge silo with a rotating arch-breaking mechanism, and is especially suitable for a flat-bottomed silo for sewage or high-viscosity viscous materials. Background technique [0002] In the current sewage treatment plant, the treatment process is that the sewage is chemically treated in the pool to become sewage with a water content of about 98%, and then enters the membrane filter press through the delivery pump for mechanical dehydration and becomes sewage with a water content of 60%-70%. The sludge filter cake is stored in the sludge silo and then dried to reach the required moisture content (below 45%) before being loaded and shipped out. Because the sludge with a moisture content of 60%-70% has the characteristics of high viscosity and strong adhesion, it is difficult to flow to the outlet of the silo by its own gravity, and arching, sticking, and blockage are pro...

Problems solved by technology

This technology can effectively solve the problem of material arching, but there are the following problems: (1) a large amount of material is pressed on the carriage, and the carriage directly slides on the guide rail, and the carriage is under great pressure and has a large friction coefficient. It requires a lot of hydraulic pressure to drive the carriage to work, that is, a large hydraulic station and power consumption are required to provide hydraulic driving force; (2) If rollers are set between the carriage and the guide rail, the carriage rolls on the guide rail, Changing the carriage from sliding friction to rolling friction can reduce the pulling force of the carriage, but the sealing requirements for the rollers are high; (3) Since the carriage keeps pushing and pulling back and forth, and the direct contact between the carriage and the guide rail , sludge and other materials contain hard sand and gravel, the carriage and guide rail are easy to wear after long-term movement, and it is difficult to ensure the horizontal movement of the hydraulic cylinder driving the carriage, resulting in damage to the cylinder; (4) With the carriage With the continuous pushing and pulling, the sliding frame will squeeze the sludge on the two side walls of the silo, and the sludge on both sides of the silo will accumulate more and more and the sliding frame will be squeezed more and more firmly. Timely cleaning will affect the stroke of the oil cylinder, and seriously damage the hydraulic oil cylinder
