Technical Field

[0001] This utility model belongs to the field of sludge treatment, and specifically relates to a sludge treatment and disposal device. Background Technology

[0002] Because sludge has a complex composition, containing heavy metals, organic matter, pathogens, and other substances, its treatment and disposal can cause secondary pollution, thus requiring stringent standards for treatment and disposal methods. Domestically and internationally, sludge treatment and disposal mainly include landfilling, composting, building material utilization, and incineration, with incineration being the most thorough method. Although sludge contains a certain amount of calorific value, it is low and cannot be incinerated alone. Furthermore, due to the characteristics of sludge, its transportation and storage also require strict adherence to regulations. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned defects and provide a sludge treatment and disposal device. Using this device, sludge and wood chips are mixed in proportion and pressed into fuel blocks, which improves the calorific value and facilitates storage and transportation.

[0004] The purpose of this utility model is achieved through the following technical solution: a sludge treatment and disposal device, characterized in that: it includes a storage tank, a conveyor, a mixer, and a briquetting machine. The storage tank includes a wood chip storage tank and a sludge storage tank. The discharge ends of the two storage tanks are respectively connected to two conveyors. The discharge ends of the conveyors are connected to the feed ends of the mixer, and the discharge ends of the mixer are connected to the briquetting machine.

[0005] A sludge treatment and disposal device further includes a feeder, wherein the feed end of the storage tank is connected to the feeder.

[0006] A sludge treatment and disposal device further includes a magnetic separator, which is suspended above the discharge end of the mixer.

[0007] A sludge treatment and disposal device further includes a packaging machine, wherein the discharge end of the briquetting machine is connected to the packaging machine.

[0008] A sludge treatment and disposal device further includes a dust collector, which is connected to the discharge end of the conveyor, the discharge end of the mixer, and the feed end of the briquetting machine via pipelines.

[0009] The beneficial effects of this utility model are:

[0010] 1. This device can be used to mix sludge and wood chips in a certain proportion and compress them into fuel blocks, thereby improving the calorific value and facilitating storage and transportation.

[0011] 2. The production line is equipped with dust collectors to remove dust at each stage, achieving dust removal throughout the entire production line.

[0012] 3. Appropriate equipment selection, reasonable layout, scientific process, and good results. Attached Figure Description

Detailed Implementation

[0016] Example: As shown in the figure, a sludge treatment and disposal device includes a feeder 1, a storage tank 2, a conveyor 3, a mixer 4, a magnetic separator 5, a briquetting machine 6, a packaging machine 7, a belt conveyor 8, and a dust collector 9. The feeder 1 is a vacuum feeder, the conveyor 3 is a variable frequency screw conveyor, and the mixer 4 is a twin-shaft screw mixer. The vacuum feeder 1 includes a sawdust vacuum feeder 1-1 and a sludge vacuum feeder 1-2. The sludge vacuum feeder 1-2 is used to draw in pre-treated powdery sludge with a moisture content of less than 40%. In the sludge storage tank 2-2 connected to it, sawdust with a moisture content of less than 20% is sucked into the connected sawdust storage tank 2-1 by a sawdust vacuum feeder 1-1 for separate storage; the discharge ends of the two storage tanks 2 are respectively connected to variable frequency screw conveyors 3, and the speed of the variable frequency screw conveyors 3 connected to the two storage tanks 2 is adjusted so that the volume ratio of sludge conveying amount to sawdust conveying amount is 1:2.5, and the materials are discharged simultaneously, and both materials fall together onto the 8-1-1# belt conveyor below the two variable frequency screw conveyors 3; 8-1-1 The discharge end of the belt conveyor is placed at the feed end of the twin-shaft screw mixer 4. Wood chips and sludge falling on the 8-1-1# belt conveyor are fed into the twin-shaft screw mixer 4. After continuous mixing by the mixer 4, the material falls onto the 8-2-2# belt conveyor below the discharge end of the mixer 4. An automatic magnetic separator 5 is suspended above the 8-2-2# belt conveyor. The automatic magnetic separator 5 removes iron from the mixture on the 8-2-2# belt conveyor. The iron-removed mixture is then conveyed by the 8-2-2# belt conveyor. The material is fed into the briquetting machine 6 connected to it and briquetting it into blocks. After being shaped, the blocks fall onto the 8-3-3# belt conveyor at the bottom of the discharge end of the briquetting machine 6, and are then fed into the hopper of the ton bag packaging machine 7 connected to it. The ton bag packaging machine 7 packages the shaped blocks and then discharges them. The packaged shaped blocks are stored as fuel and then transported to a power plant for incineration and power generation. The fuel blocks made from mixed sludge and wood chips processed by this device have a calorific value exceeding 3000 kcal, which meets the calorific value requirements of the power plant and can be used as fuel for incineration. This device is connected to the dust collector 9 via pipelines above the discharge end of the variable frequency screw conveyor 3, the discharge end of the twin-shaft screw mixer 4, and the feed end of the briquetting machine 6, respectively, to achieve dust removal throughout the entire process.
