Abstract
Description
Technical Field
[0001] The utility model relates to the field of water reuse, and more specifically, to a sand washing water sand discharge device. Background Art
[0002] The semiconductor industry requires a large amount of high-purity silicon. In the process of producing high-purity silicon, a large amount of high-purity water is needed for sand washing and flushing steps. The water after flushing is often mixed with impurities such as mud and sand.
[0003] Sand washing water needs to be separated from impurities before it can be reused.
[0004] The present application aims to provide a sand washing water sand discharge device, which can efficiently and quickly settle impurities and achieve stable operation of subsequent water use. Summary of the invention
[0005] The utility model overcomes the shortcomings of low recovery efficiency, large floor space, low efficiency and insufficient stability of existing sand washing water, and provides a sand washing water sand discharge device, which can efficiently and quickly settle impurities and realize stable operation of subsequent water use.
[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0007] A sand washing water sand discharge device comprises a sand settling tank and a guide tube arranged in the middle of the sand settling tank, the bottom of the guide tube is open and there is a preset distance between the bottom wall of the sand settling tank, the sand settling tank is provided with a water inlet and a water outlet, the water inlet is connected to a water inlet pipe, the water inlet pipe extends into the guide tube, and a water outlet weir is provided near the top of the sand settling tank, and the water outlet is arranged above the water outlet weir.
[0008] The structure also adopts the principle of sedimentation. After the water enters the guide tube from the water inlet pipe, it first flows downward and turns out from the bottom of the guide tube in the circumferential direction. Then, under the push of subsequent water, it naturally flows upward and completes the sedimentation in the above process. Compared with not setting up a guide tube, the above process can achieve a better sedimentation effect. First of all, the water inlet and sedimentation areas are separated to prevent the sediment that has settled from gaining power again and continuing to mix with the water. Secondly, by turning out from the guide tube, the water body and the sediment are initially separated by taking advantage of the different densities of the water body and the sediment (that is, the speed of the water body in the axial direction of the guide tube is less than the speed of the sediment, thereby creating a separation of the water body and the sediment). The above structure makes it possible for the interface between the recycled water and the sediment to be clear and will not turn over after sedimentation. Further screening is then carried out with the help of the outlet weir, thereby further improving the purity of the water discharged from the outlet.
[0009] Preferably, the sand settling tank is provided with a bottom wall that is larger at the top and smaller at the bottom, in a funnel shape. The structure enables the sand to gather preferentially at the lowest point, which is beneficial for sand discharge.
[0010] Preferably, the bottom wall of the grit chamber is coaxial with the guide tube. The structure allows the grit to be preferentially concentrated at the lowest point of the grit chamber.
[0011] Preferably, a sand discharge pipe is connected to the lowest part of the bottom wall. The structure facilitates rapid sand discharge after sand accumulation.
[0012] Preferably, a switch valve is provided on the sand discharge pipe.
[0013] Preferably, the sand discharge pipe is further connected to an air flushing pipe, and the air flushing pipe is connected to an air pump. The arrangement of the air flushing pipe and the air pump facilitates flushing.
[0014] Preferably, the sand discharge pipe comprises a three-way pipe, the three-way pipe is respectively connected to the bottom wall of the sand settling tank and the air flushing pipe, and each pipe opening of the three-way pipe is respectively connected to a switch valve.
[0015] Preferably, the switch valve is a pneumatic valve.
[0016] Compared with the prior art, the utility model has the beneficial effect of quickly performing sand separation through the provision of a sand settling tank, thereby achieving stable operation of subsequent water use. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present disclosure is further described below in conjunction with the accompanying drawings and embodiments.
[0022] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.
[0023] Example:
[0024] A sand washing water sand discharge device, Figure 1 , 2 As shown, it includes a grit chamber 1 and a guide tube 2 arranged in the middle of the grit chamber 1 . The bottom of the guide tube 2 is open and there is a preset distance between the guide tube 2 and the bottom wall of the grit chamber 1 .
[0025] In other words, the guide tube 2 is suspended relative to the grit chamber 1. In this embodiment, the guide tube 2 is positioned in the middle of the grit chamber 1 by a rigid rod.
[0026] The grit chamber 1 is provided with a bottom wall that is larger at the top and smaller at the bottom, in a funnel shape. The structure allows the sediment to gather at the lowest point first, which is conducive to sand discharge. In addition, the bottom wall of the grit chamber 1 is smooth, which avoids the large friction between the sediment and the sand, which makes it difficult to remove the sand.
[0027] The bottom wall of the grit chamber 1 is coaxial with the guide tube 2. The structure allows the grit to be concentrated at the lowest point of the grit chamber 1 first.
[0028] A sand discharge pipe 7 is connected to the lowest point of the bottom wall. The structure facilitates the rapid discharge of sand after the sand is accumulated. A switch valve 9 is provided on the sand discharge pipe 7. The sand discharge pipe 7 is also connected to an air flushing pipe 10, and the air flushing pipe 10 is connected to an air pump. The arrangement of the air flushing pipe and the air pump facilitates flushing. The sand discharge pipe 7 includes a three-way pipe 8, and the three-way pipe 8 is respectively connected to the bottom wall of the sand settling tank 1 and the air flushing pipe 10, and each pipe opening of the three-way pipe 8 is respectively connected to a switch valve 9. In some embodiments, the switch valve 9 is a pneumatic valve.
[0029] When discharging sand, close the switch valve 9 of the inflation pipe and open the other two switch valves 9 to discharge sand; when inflating and cleaning, close the switch valve 9 at the bottom and open the other two switch valves 9 to clean.
[0030] The grit chamber 1 is provided with a water inlet 3 and a water outlet 4. The water inlet 3 is connected to a water inlet pipe 5. The water inlet pipe 5 extends into the guide tube 2. A water outlet weir 6 is provided near the top of the grit chamber 1. The water outlet 4 is arranged above the water outlet weir 6.
[0031] The design of the water outlet weir 6 is a conventional design in the art and will not be described in detail in this application.
[0032] The structure also adopts the principle of sedimentation. After the water enters the guide tube 2 from the water inlet pipe 5, it first flows downward, turns out from the bottom of the guide tube 2 in the circumferential direction, and then naturally flows upward under the push of subsequent water, and completes the sedimentation in the above process. Compared with not setting the guide tube 2, the above process can achieve a better sedimentation effect. First of all, the water inlet and sedimentation areas are separated to prevent the sediment that has settled from gaining power again and continuing to mix with the water. Secondly, by turning out from the guide tube 2, the water body and the sediment are initially separated by taking advantage of the different densities of the water body and the sediment (that is, the speed of the water body in the axial direction of the guide tube 2 is less than the speed of the sediment, thereby creating the separation of the water body and the sediment). Further screening is then carried out with the help of the outlet weir 6, thereby further improving the purity of the water discharged from the outlet 4.
[0033] The above-described embodiments are only preferred solutions of the present invention and are not intended to limit the present invention in any form. Other variations and modifications are possible without exceeding the technical solutions described in the claims.
