An easy-to-clean sludge dewatering separator

Abstract

The invention discloses a convenient-to-clean sludge dehydration separator and aims to solve the problem that a sludge dehydration separator is poor in cleaning effect. According to the technical scheme for solving the problem, the convenient-to-clean sludge dehydration separator mainly comprises a mounting tube, wherein the mounting tube extends into a supply chamber in an axial direction and isclose to a separated substance outlet; a macromolecule agglutination agent injection tube and a sludge injection tube penetrate through the mounting tube in the axial direction, extend into the supplychamber and are communicated with the supply chamber; a channel which is in sliding connection with an inorganic agglomerant injection tube is formed inside the mounting tube; a plurality of throughholes communicated with a separation chamber are formed in the channel; the inorganic agglomerant injection tube is communicated with a water supply tube; one end extending into the channel, of the inorganic agglomerant injection tube, is sealed; a first baffle block and a second baffle block which are both positioned at the downstream of a water supply tube are arranged on the inorganic agglomerant injection tube; a plurality of openings are formed in the inorganic agglomerant injection tube; the first baffle block is propped against one end of a mounting tube; all openings are communicated with the plurality of the through holes respectively; the second baffle block is propped against the other end of the mounting tube; then a part of the openings are communicated with the supply chamber; the other part of the openings are aligned to and communicated with the through holes.

Description

technical field [0001] The invention relates to a convenient cleaning sludge dehydration separator. Background technique [0002] The sludge dehydration separator uses centrifugal rotation to concentrate and dehydrate the sludge. In order to improve the performance of concentration and dehydration, two kinds of coagulants (inorganic coagulant and polymer coagulant) are generally mixed into the sludge, which not only reduces the dewatering pollution The water content of the mud is increased, and the clarity of the dehydration separation liquid is increased, but the inorganic coagulant remaining in the inorganic coagulant injection pipe is easy to agglomerate and block the inorganic coagulant injection pipe. In order to solve the above problems, the prior art provides a A kind of sludge dehydration separator (CN102448896), the water supply pipe is connected with the inorganic coagulant injection pipe, so as to supply water to the inorganic coagulant injection pipe, which not o...

[0002] The sludge dehydration separator uses centrifugal rotation to concentrate and dehydrate the sludge. In order to improve the performance of concentration and dehydration, two kinds of coagulants (inorganic coagulant and polymer coagulant) are generally mixed into the sludge, which not only reduces the dewatering pollution The water content of the mud is increased, and the clarity of the dehydration separation liquid is increased, but the inorganic coagulant remaining in the inorganic coagulant injection pipe is easy to agglomerate and block the inorganic coagulant injection pipe. In order to solve the above problems, the prior art provides a A kind of sludge dehydration separator (CN102448896), the water supply pipe is connected with the inorganic coagulant injection pipe, so as to supply water to the inorganic coagulant injection pipe, which not only dilutes the inorganic coagulant, but also ensures that the inorganic coagulant is injected into the separation chamber in a large range, and realizes Cleaning of the inorganic coagulant injection system, but the cleaning liquid in the inorganic coagulant injection system cannot flow into the supply chamber in large quantities, so that the inorganic coagulant injection system, supply room and Overall cleaning of the separation chamber
