Description

Technical Field

[0001] The utility model relates to the field of environmental protection production, in particular to a device for using an emulsion type sludge dehydrating agent. Background Art

[0002] In environmental engineering and the chemical industry, sludge dewatering is a crucial step in treating sludge generated by wastewater. The purpose of sludge dewatering is to reduce the moisture content of sludge. Untreated sludge may contain large amounts of organic and inorganic matter, which can pollute the land if discharged or landfilled directly. Dewatering can reduce the volume and toxicity of sludge, thereby lowering the degree of land pollution. Dewatering can reduce the volume of sludge and lower the cost of treatment and disposal. Relatively less equipment and energy are required to treat smaller volumes of sludge, thus saving operating costs. By dewatering and recovering useful substances from sludge, resource utilization efficiency can be improved. This helps achieve the goals of a circular economy and reduce resource waste and consumption. Traditional sludge dewatering technologies include natural sedimentation, filter pressing, and centrifugation. These methods have varying degrees of limitations in terms of treatment efficiency, equipment footprint, operational complexity, and energy consumption. For example, patent number CN208883690U discloses a snail sludge dewatering machine, which has the following shortcomings in the field of sediment dewatering: 1. It is difficult to perform preliminary treatment on the incoming sediment, and the device is prone to clogging. 2. It is difficult to perform in-depth dehydration treatment on the sediment, and the sediment dehydration rate is not high enough. Utility Model Content

The fender 201 between the first bracket 202 and the fourth bracket 202, the bearing protection shell 206 fixed between the first bracket 202 and the second bracket 203, and the pulley 207 fixed to one end of the spiral shaft 215; the four brackets connected to the square tube bracket 101 are used to connect the dehydration mechanism 2 above to the frame 1, and there is an opening between each first bracket 202 and the second bracket 203 for placing the first bearing 211 and the second bearing 216. There is also a bearing in the shaft head sleeve 204 installed on the outside of the third bracket 208, which is integrated in the shaft head sleeve. Three bearings are used to install the spiral shaft 215, so that the rotation resistance of the spiral shaft 215 is smaller and the equipment runs more smoothly. The sand-stopping plate 213 is bolted with 21 2 is fixed to the outside of the third bracket 208, and there is a first spiral 2151 inside the spiral shaft. The spiral angle of the thread is large, and it is mainly responsible for pushing the upper sediment into the second spiral 2152 to prevent the sediment from clogging at the inlet. The spiral angle of the second spiral 2152 is small, and the speed of pushing the sediment is slow, which can make the sediment fully dehydrated. The spiral shaft 215 has a C20 chamfer on the side close to the third bracket 208, so that there will be a gap between it and the third bracket 208. The dehydrated sediment is pushed out from the gap. The dehydration channel 214 is fastened between the third bracket 208 and the fourth bracket 210 with bolts. The dehydration channel is made of two semicircular parts fixed with bolts. There are useful The rectangular iron sheet is fixed with bolts, and there is an opening at the bottom of each semicircular part for placing a filter screen 209. The filter screen can separate mud and water. The water is discharged through the filter screen and flows out through the lower water tank 107 and the lower water pipe 103. A pulley 207 is fixed on the other side of the spiral shaft 215. The pulley 207 is connected to the pulley on the dehydration motor 108 by a belt to transmit power.

The first transmission gear 302 outside the first crushing wheel 303 meshes with the second transmission gear 306, driving the second crushing wheel 305 to rotate, thereby crushing larger solid particles in the sediment, preventing the dewatering device below from being stuck and stopped due to large solid particles, and also preliminarily separating the sediment from the water. The external crushing channel 304 allows the sediment to flow downward to the fixed position.

[0031] The reaction vessel 4 includes a tank body 402 fixed above the crushing channel 304, an insert plate 401 inserted into the inside of the tank body 402, and a nozzle 403 arranged on the side of the tank body 402; the tank body 402 is square at the bottom and circular at the top. The bottom is used to fix the insert plate 401, and the top is used to store mud and sand for reaction with the emulsion type sludge dehydrating agent. The nozzle 403 at the top is connected to an external water pipe for evenly spraying the emulsion type sludge dehydrating agent on the mud and sand. When the mud and sand react with the emulsion type sludge dehydrating agent, the insert plate 401 is in an inserted state. There are small holes 4011 in the insert plate 401 for discharging water generated during the reaction to prevent the mud and sand from absorbing water again. When the reaction is completed, the insert plate 401 is pulled out to allow the mud and sand to flow into the crushing device 3 for crushing. The crushed mud and sand then flow into the dehydration device 2.

[0032] Working principle:

[0033] During operation, mud and sand are first poured into the reaction device 4. A nozzle 403 is connected to a water pipe and an emulsion-type sludge dehydrating agent at a concentration of 20% to 45% of the weight of the absolute dry sludge is sprayed. The sludge is allowed to stand for 10 to 20 minutes. The water generated during the reaction flows out through the holes 4011 in the insert plate 401. After the reaction is complete, the crushing motor 105 and the dehydration motor 108 are turned on, and the baffle 401 is then withdrawn. The sludge passes through a pair of reverse-rotating first crushing wheels 303 and 305 of the crushing mechanism 3. The first crushing wheel 303 and the second crushing wheel 305 will crush large solid particles into small particles. The first crushing wheel 303 and the second crushing wheel 305 are provided with crushing teeth. The gap between the crushing teeth is small, which can preliminarily dehydrate the sludge. After passing through the crushing mechanism, the sludge flows into the dewatering mechanism 2. The first spiral 2151 on the spiral shaft 215 inside the dewatering mechanism 2 will push the sludge forward quickly, while the second spiral 2152 in the front pushes the sludge at a slower speed. The sludge at the rear will squeeze the sludge in the front, and the sludge is completely dehydrated. The dehydrated sludge is discharged through the gap between the third bracket 208 and the chamfered angle in front of the spiral shaft 215. The water flows into the lower sink 107 through the filter screen 209 and is discharged through the drain pipe 103.
