Description

Technical Field

[0001] This utility model relates to the technical field of slurry dewatering equipment, and in particular to a slurry dewatering structure. Background Technology

[0002] After preliminary processing, industrial raw materials such as minerals and coal slime are formed into slurry, which contains a large amount of water. This affects the subsequent pressing and transportation processes, so the slurry needs to be dehydrated.

[0003] Currently, slurry dewatering mainly relies on centrifugal separation technology, which requires pumping the slurry from the storage tank and transferring it to centrifugal equipment, where the solid materials and water of the slurry are separated.

[0004] Centrifuge equipment occupies a large area, and the construction, operation and maintenance costs are high. The entire dewatering process is relatively complex. There is a lack of existing technologies that can remove water from the slurry and meet the moisture content requirements of the slurry at a lower cost. Utility Model Content

[0005] In order to improve the problem of water removal from slurry in the above-mentioned background art, this utility model provides a slurry water removal structure.

[0006] The slurry dewatering structure provided by this utility model adopts the following technical solution:

[0007] A slurry dewatering structure includes a storage tank for storing slurry. Multiple grooves are spaced apart on the bottom wall of the storage tank. A water suction pipe is laid in the groove. The water suction pipe is connected to a main pipeline through a T-joint. A vacuum pump is installed at the end of the main pipeline to form negative pressure for water suction.

[0008] The suction pipe has suction holes arranged on it, and a filter screen for filtering solid materials in the slurry is fitted on the outside of the suction pipe. The filter screen is a 200-500 mesh stainless steel filter screen to ensure that water can pass through and prevent solid materials from being sucked in.

[0009] Preferably, a quick clamp is fixedly installed in the trench, and the water suction pipe is fastened in the trench by the quick clamp, which restricts the water suction pipe.

[0010] Preferably, a switch valve is installed on the main pipeline. When it is necessary to remove water from the slurry, the switch valve and vacuum pump are opened to remove water.

[0011] Preferably, a moisture content sensor is installed on the inner wall of the storage tank to detect the moisture content of the slurry. The moisture content sensor is communicatively connected to a display device installed outside the storage tank, which facilitates operators to monitor the moisture content of the slurry in real time.

[0012] Preferably, the upper surface of the storage tank is covered with a smooth composite ceramic layer, which facilitates the subsequent cleaning and recycling of the slurry solids accumulated on the upper surface of the storage tank after water removal.

[0013] In summary, this utility model has the following beneficial technical effects:

[0014] 1. This utility model modifies the storage tank for storing slurry, allowing the slurry to be dehydrated within the tank. A groove is created on the bottom wall of a sub-storage tank, and a suction pipe is laid. The suction pipe is connected to a main pipeline and a vacuum pump. When dehydration is required, the vacuum pump is activated, drawing water from the slurry through the main pipeline and suction pipe, achieving efficient in-situ dehydration. Only residual solid material remains in the storage tank. This utility model meets the slurry's moisture content requirements at a relatively low cost.

[0015] 2. This utility model has a simple structure. A filter screen is installed on the outside of the suction pipe to filter solid materials and prevent the suction holes from being blocked. The suction holes arranged on the suction pipe absorb water from the slurry. The suction pipe is fastened in the groove by a quick clamp for easy replacement.

[0016] 3. By installing a moisture content sensor on the inner wall of the storage tank, the moisture content of the slurry can be monitored in real time, making it convenient for operators to observe. Attached Figure Description

[0023] The following combination Figures 1-5 The present invention will be described in further detail below.

[0024] This utility model discloses a slurry dewatering structure.

[0025] Reference Figure 1 A slurry dewatering structure includes a storage tank 1 for storing slurry. The storage tank 1 has a rectangular structure. Multiple grooves 2 are spaced apart on the bottom wall of the storage tank 1. Water suction pipes 3 are laid in the grooves 2. The water suction pipes 3 are connected to a main pipeline 5 through a T-joint 4. A vacuum pump 6 is installed at the end of the main pipeline 5 to form a negative pressure to suck out the water in the slurry.

[0026] Reference Figure 5 The suction pipe 3 has suction holes 7 arranged on it. The suction pipe 3 is a UPVC water pipe. The outside of the suction pipe 3 is fitted with a filter screen 8 for filtering solid materials of the slurry. The filter screen 8 is a 200-500 mesh stainless steel filter screen. Under the filtration of the stainless steel filter screen, water is sucked in by the suction pipe 3, and solid materials are blocked.

[0027] Reference Figure 1 , Figure 2 , Figure 3 A quick clamp 9 is fixedly installed in the groove 2. The suction pipe 3 is fastened in the groove 2 by the quick clamp 9. When cleaning the filter screen 8 and the suction pipe 3, the quick clamp 9 is used to quickly fasten the suction pipe 3, so as to achieve quick disassembly and assembly. The disassembly and assembly time is less than 30 minutes.

[0028] Reference Figure 1 , Figure 2 , Figure 3 The quick clamp 9 includes a semi-circular upper clamp and a lower clamp. The lower clamp is fixed in the groove 2. The upper clamp and the lower clamp are fastened by quick snaps at the ends and restrict the suction pipe 3. The design of the upper and lower clamps greatly shortens the maintenance time of the suction pipe 3.

[0029] Reference Figure 1 A switch valve 10 is installed on the main pipeline 5. When it is necessary to remove water from the slurry, the switch valve 10 and the vacuum pump 6 are opened to remove water.

[0030] Reference Figure 1 , Figure 2 A moisture content sensor 11 is installed on the inner wall of the storage tank 1. The moisture content sensor 11 is communicatively connected to a display device 12 installed outside the storage tank 1. The moisture content sensor 11 can detect the moisture content of solid-liquid mixtures such as soil and mortar. The probe of the moisture content sensor 11 generates voltage changes by emitting and receiving electromagnetic waves of a certain frequency. The moisture content can be calculated from the relationship between voltage and moisture. The moisture content sensor 11 transmits the detection data to the display device 12 outside the storage tank 1 in the form of an electrical signal. The controller inside the display device 12 receives, calculates, and feeds back the detection results on the screen on the surface of the display device 12.

[0031] Reference Figure 2 , Figure 4 The upper surface of the storage tank 1 is covered with a smooth composite ceramic layer 13. The composite ceramic layer 13 does not cover the trench 2. By laying the composite ceramic layer 13, it is easier to separate the slurry solid material accumulated on the upper surface of the storage tank 1, thereby improving wear resistance.

[0032] The implementation principle of the slurry dewatering structure in this embodiment of the utility model is as follows: Multiple grooves 2 are opened at intervals on the bottom wall of the storage tank 1. The suction pipe 3 is laid in the grooves 2 and fastened with quick clamps 9, connecting the suction pipe 3 to the main pipeline 5. During dewatering, the switch valve 10 is opened and the vacuum pump 6 is started. The suction pipe 3 absorbs water from the slurry. When the moisture content sensor 11 detects that the moisture content of the slurry has reached the specified limit, the operator is reminded to turn off the vacuum pump 6 and the switch valve 10. The solid material of the slurry accumulated on the surface of the storage tank 1 is cleaned and recycled using a forklift or shovel. The moisture content of the slurry after dewatering meets the requirements for pressing.

[0033] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
