Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, and more specifically, to a dry-wet separation device for hydrated sludge based on municipal street sweeping soil. Background Technology

[0002] Currently, to improve the quality of sanitation operations, road sweeping has shifted from primarily dry sweeping to primarily washing and sweeping. While ensuring high-quality operations, this has also brought new problems, namely, the excessively high moisture content of the street sweeping soil. The street sweeping soil collected during washing and sweeping operations contains a large amount of water, and a large amount of wastewater is mixed in again during the unloading and washing process, resulting in the high moisture content of the dry components failing to meet the receiving requirements of the transfer station. At the same time, the excessively high moisture content of the street sweeping soil can easily cause screen clogging in the sorting equipment, and it can also pose a risk of secondary pollution during the transfer to the sorting station, thus affecting the lifespan of the transfer vehicles.

[0003] In existing technologies, the processing structure for street sweeping soil with excessive moisture content usually only involves draining without dehydration. The moisture content of the street sweeping soil after this method is still too high, and the material transported to the transfer station will leak during the transfer process, failing to meet the receiving standards of the transfer station. Alternatively, after the operation is completed, the collected street sweeping soil is directly dumped at the unloading point or garbage bin, and then air-dried to control the moisture before collection and transfer. This method has the disadvantages of garbage exposure, significant on-site environmental pollution, long overall time consumption, and large site area occupation, which seriously affects the collection and transportation efficiency of street sweeping soil. Utility Model Content

[0004] To address this, the present invention provides a hydrated sludge dry-wet separation device based on municipal street sweeping soil, in order to solve the technical problems in the prior art where street sweeping soil with excessive water content is difficult to filter and dehydrate sufficiently before transportation, and is prone to causing on-site environmental pollution, resulting in low overall collection and transportation efficiency of street sweeping soil.

The filter mud lifting structure 3, corresponding to the conveying foundation structure 1, further lifts and conveys the filter mud after the first step of impurity filtration. This utilizes the weight of the water to achieve sludge-liquid separation filtration, and the filtered sludge can be transported to an external container, improving the overall filtration efficiency and its functional practicality. The specific settings are as follows:

[0056] Please refer to Figures 1 to 3 The conveying foundation structure 1 includes a horizontally placed filter chamber 11 and a lifting filter chamber 12 integrally fixedly connected; wherein, the horizontally placed filter chamber 11 extends horizontally, the lifting filter chamber 12 extends obliquely, and the bottom end of the lifting filter chamber 12 is connected to one side end of the horizontally placed filter chamber 11. The top end of the lifting filter chamber 12 has a filter chamber outlet 13, which is used to form a lifting, conveying and discharge route for sludge filtration.

[0057] Please continue to refer to this. Figures 1 to 3 The filter screen structure 2 includes a screen side baffle 21 and a filter screen layer 22 fixedly disposed on the inner side of the screen side baffle 21. The screen side baffle 21 and the filter screen layer 22 are both fixedly assembled at the top position of the flat filter cavity 11, and the filter screen layer 22 is correspondingly connected to the interior of the flat filter cavity 11, so as to effectively achieve the first step of filtering out sand blocks or branches and other debris by using the filter screen layer 22 corresponding to the conveying base structure 1.

[0058] As a preferred embodiment, the screen side baffle 21 is provided with a mud inlet, and the height of the outer edge of the screen side baffle 21 gradually increases from the side of the mud inlet toward the opposite side, so as to improve the blocking effect of the opposite side of the mud inlet through the screen side baffle 21, thereby reducing the overflow when dumping mud.

[0059] More preferably, please refer to Figure 5 The screen side baffle 21 is also fixedly provided with a material pouring side baffle 23 on both sides of the mud inlet, so as to further improve the material pouring blocking and overflow prevention performance through the material pouring side baffle 23.

[0060] Please refer to Figure 3 and Figure 4The filter mud lifting structure 3 includes a reduction motor 31, a first transmission sprocket 32, a second transmission sprocket 33, a directional tensioning sprocket 34, a first transmission chain 35, a second transmission chain 36, and a filtrate lifting support plate 37. The base of the reduction motor 31 is fixedly mounted on the outer wall of the lifting filter chamber 12. Two sets of the first transmission sprocket 32, the second transmission sprocket 33, and the directional tensioning sprocket 34 are provided.

The rotational kinetic energy output by the reduction motor 31 drives the second transmission chain 36 through the first transmission chain 35. The second transmission chain 36, in conjunction with the filtrate lifting plates 37, further lifts and guides the filter mud that has fallen to the bottom inner wall of the flat filter chamber 11 after the first step of impurity filtration along the bottom inner wall of the lifting filter chamber 12, so that the filter mud can achieve automatic separation and filtration of mud and liquid by the weight of the water and be discharged through the filter chamber outlet 13, thereby significantly improving the overall filtration efficiency.

[0061] The filtrate lifting support plate 37 includes a support plate body and a plurality of filtrate holes formed in the support plate body, which are used to lift the filter mud through the support plate body and further enhance the overall filtrate effect by means of the filtrate holes.

Please refer to [link / reference needed]. Figures 5 to 7 The hydrated sludge conveying and filtering device further includes a spiral extrusion structure 4, which is used to spirally extrude the sludge after the filtrate has been lifted, thereby further improving the sludge-liquid separation effect. The specific configuration is as follows:

[0064] The spiral extrusion structure 4 includes a spiral extrusion housing 41 and a motor-driven spiral blade 42 that is interchangeably mounted at the center of the spiral extrusion housing 41. A spiral extrusion channel 45 is formed between the motor-driven spiral blade 42 and the spiral extrusion housing 41. The blade spacing of the motor-driven spiral blade 42 gradually decreases, so that the spiral extrusion channel 45 gradually forms an extrusion effect.

[0065] The spiral extrusion channel 45 has a spiral extrusion inlet 43 at one end of the spiral extrusion housing 41, and a spiral extrusion outlet 44 at the other end of the spiral extrusion housing 41. The spiral extrusion inlet 43 is connected to the filter chamber outlet 13. The spiral blades 42 are driven by a motor to rotate and drive the mud after the filtrate is lifted, so that the mud is spirally extruded through the spiral extrusion channel 45, which further improves the mud-liquid separation effect.

[0066] It should be noted that the spiral extrusion housing 41 and the motor-driven spiral blades 42 are arranged vertically or obliquely to complete the lifting extrusion conveying and further enhance the overall filtration effect.

[0067] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
