Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sludge concentration treatment, in particular to sludge concentration equipment with a pretreatment mechanism. Background Art
[0002] Sludge thickening equipment is used to reduce sludge volume and increase its solids content. Sludge is a waste product generated during water treatment and contains a large amount of water and solid particles. Sludge thickening equipment removes some of the water from the sludge through physical or mechanical methods, increasing the solids content and reducing the volume of sludge required for subsequent treatment (such as dehydration, drying, or incineration).
[0003] The basic principle of some sludge thickening equipment in the existing technology is to send the sludge into a centrifugal screen driven by a driving motor. The sludge inside the centrifugal screen will be separated into solid and liquid due to centrifugal force. However, when the amount of sludge inside the centrifugal screen is large, this single sludge thickening method has a slow efficiency in sludge thickening and is difficult to meet actual production needs. Summary of the Invention
[0004] The purpose of the utility model is to solve the problem that the basic principle of some sludge thickening equipment in the prior art is to feed the sludge into a centrifugal screen cylinder driven by a driving motor, and the sludge inside the centrifugal screen cylinder will be separated into solid and liquid due to centrifugal force. However, when the amount of sludge inside the centrifugal screen cylinder is large, this single sludge thickening method has a slow efficiency in sludge thickening and is difficult to meet actual production needs. A sludge thickening equipment with a pretreatment mechanism is proposed.
[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0006] A sludge thickening device with a pretreatment mechanism comprises a vertical cylinder and an inverted U-frame, wherein the inverted U-frame is fixedly provided on the top of the vertical cylinder, an extrusion cylinder is fixedly provided at the middle position of the top of the inverted U-frame, a support plate is fixedly provided at the bottom of the inner cavity of the vertical cylinder, a circular array of release grooves is provided on the top of the support plate, a centrifugal motor is fixedly provided at the middle position of the bottom of the support plate, a centrifugal net cylinder is fixedly provided at the output end of the centrifugal motor, and a pretreatment mechanism for crushing the sludge is provided on one side of the extrusion cylinder at the top of the inverted U-frame.
[0007] Optionally, an extrusion cover is fixedly provided at the output end of the extrusion cylinder, and an introduction hole is opened at the top of the extrusion cover.
[0008] Optionally, the pretreatment mechanism includes a buffer bucket, a stirring motor, and a switch valve. The buffer bucket is fixedly provided on the top of the inverted U-frame, and the stirring motor is fixedly provided on the inverted U-frame directly above the buffer bucket.
[0009] Optionally, a stirring blade is fixedly provided at the output end of the stirring motor, and the stirring blade extends into the interior of the buffer bucket, and a switch valve is provided at the bottom of the buffer bucket.
[0010] Optionally, the extrusion cover is rotatably connected to a closing cover at the top of the introduction hole, and an auxiliary ball is fixedly provided at the top edge of the closing cover.
[0011] Optionally, the bottom of the vertical cylinder is configured to be in an inverted bucket shape, the bottom of the vertical cylinder is provided with through holes, and the bottom of the vertical cylinder is provided with supporting legs in a circular array.
[0012] Compared with the prior art, the present invention has the following advantages:
[0013] 1. The utility model is additionally provided with an extrusion cover on the top of the centrifugal net cylinder. An extrusion cylinder is provided on the top of the extrusion cover. The extrusion cylinder drives the extrusion cover to move downward. When the centrifugal net cylinder uses centrifugal force to separate solid and liquid, it also squeezes the solid-liquid mixture inside the centrifugal net cylinder, which greatly improves the efficiency of sludge solid-liquid separation.
[0014] 2. This utility model features an additional sludge pretreatment mechanism on top of the centrifugal drum to break up any lumps that may be present in the sludge. Untreated sludge clumps, especially those containing hard impurities, can cause excessive wear on the centrifugal drum, separator, and other components during operation. By pre-treating and breaking up lumps, the sludge becomes more uniform and softer, reducing wear on mechanical components, thereby extending the equipment's service life and reducing maintenance costs.
