Description

TECHNICAL FIELD

[0001] The utility model relates to sludge treatment technical field especially is related to a kind of ultrasonic wave collaborative sludge pulping device. BACKGROUND

[0002] Chemical manganese dioxide is prepared by the oxidation of divalent manganese salt or the reduction of permanganate, and a large amount of salt is contained in the mud cake after plate-and-frame filter pressing. The mud cake needs to be slurried and washed to improve its chemical purity. After plate-and-frame filter pressing (squeezing pressure of 1.6 MPa), the moisture content of chemical manganese dioxide is 37-46%, and the center of the mud cake presents a hard solid state. The conventional pulping equipment cannot completely crush and slurry the mud cake.

[0003] Patent CN213467503U discloses a comb tooth type sludge pulping device, which comprises a reduction motor, a tank body, a static stirrer and a dynamic stirrer. The reduction motor is arranged at the top of the tank body, and the static stirrer and the dynamic stirrer are arranged inside the tank body. There is no contact between the static stirrer and the dynamic stirrer. The reduction motor is drivingly connected to the dynamic stirrer. The dynamic stirrer and the static stirrer are provided with a comb tooth structure at their upper and lower ends. The dynamic stirrer is horizontally arranged at the opposite end of the central stirring shaft. The dynamic stirrer has an angle iron structure. The angles of the dynamic stirrer are consistent. The comb tooth type stirrer structure combines the static and dynamic functions. The device can mix the waste tar and vinegar residue with the biochemical sludge after the waste tar and vinegar residue are dispersed, increase the contact area between the tar particles and the microorganisms, and make the tar particles quickly decompose into harmless substances under the biochemical action. The comb tooth type sludge pulping device can also be applied to the pulping treatment of high-concentration sludge in other industries. However, the bottom and inner wall of the device are smooth and have no friction. The dry sludge particles with the maximum weight accumulate at the bottom, and the dry sludge particles with slightly smaller weight move along the inner wall under the action of centrifugal force, so that the static stirrer and the dynamic stirrer cannot completely crush and slurry the dry sludge particles.

[0004] Therefore, there is an urgent need for a sludge pulping device that can completely crush and slurry dry sludge particles. UTILITY MODEL CONTENTS
