Description

Technical Field

[0001] The invention relates to the technical field of Yellow River water irrigation, and in particular to a water-sediment separation integrated device for Yellow River water. Background Art

[0002] The agricultural water consumption in the irrigation areas of the Yellow River is huge. For many years, the extensive flood irrigation method has greatly wasted the precious water resources of the Yellow River. The irrigation water utilization coefficient is only 0.4. If the irrigation water utilization coefficient can reach 0.8, the agricultural irrigation water can save 2.8 billion m3 of water, which will produce huge social, economic and ecological benefits. In order to explore the potential of agricultural water saving, the irrigation areas along the Yellow River have successively introduced advanced irrigation methods such as sprinkler irrigation and drip irrigation. Drip irrigation is one of the most effective water-saving technologies at present, but due to the high sand content and impurities in the Yellow River cement, how to filter the sand impurities at low cost and high efficiency has become the main problem facing the current development of drip irrigation.

[0003] The existing technology for treating impurities in the Yellow River drip irrigation water source mainly uses equipment and facilities such as a sedimentation tank combined with a combined physical filter for filtration. The Yellow River water first enters the sedimentation tank for initial sedimentation to eliminate large particles of sediment impurities. After the initial sedimentation, it is pressurized by a water pump and enters the combined filter to remove smaller impurities before entering the drip irrigation system. However, the sedimentation tank combined with the combined physical filter has a large area of ​​​​sedimentation tank. On average, a single sedimentation tank occupies 20-50 acres, which requires a high investment and is not suitable for large-scale promotion and use. Secondly, the combined physical filter can only filter solid impurities, and the colloidal microorganisms in the Yellow River water are still difficult to remove, which can easily cause dripper blockage problems, affecting the irrigation effect. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an integrated water-sediment separation device for the Yellow River water, realize the effective filtration of the Yellow River water, ensure the drip irrigation water source demand of the Yellow River irrigation area, reduce the occupied area required for the Yellow River water treatment, reduce its investment cost, and produce better economic benefits.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0006] A water-sand separation integrated device for Yellow River water, comprising a flocculant adder for adding flocculants, a booster pump connected to the flocculant adder, and a water-sand separator connected to the booster pump; wherein the water-sand separator comprises a shell, a water inlet arranged on the shell and connected to the booster pump, a filter material for flocculent filtering arranged in the shell, a sand separator arranged in the shell and used to separate Yellow River water sediment from the filter material, a drain outlet arranged on the upper part of the shell and used to discharge filtered clean water, a sand outlet arranged on the bottom of the shell and used to discharge filtered sediment and filter material, a sedimentation and stratification tank arranged below the sand outlet and used to deposit and screen the filter material and Yellow River water sediment, and a sedimentation and stratification tank arranged on the sedimentation and stratification tank A stratified screen in the stratification tank, a feed pipe arranged on the sedimentation stratification tank and whose inlet is located above the stratification screen, a feed pump connected to the feed pipe, a filter material washing tank arranged above the shell and connected to the feed pump, a stirring tank arranged below the filter material washing tank, a filter material sedimentation tank and a floc discharge pipe for discharging flocs arranged below the stirring tank, a sediment discharge pipe arranged on the sedimentation stratification tank and whose outlet is located below the stratification screen, a solenoid valve arranged on the sediment discharge pipe and used to control the opening and closing of the sediment discharge pipe, and an electric control box for controlling the solenoid valve, the feed pump, the booster pump, and the stirring tank; wherein the particle size of the filter material is larger than the particle size of the sediment in the Yellow River water.

[0007] Furthermore, an overflow device for further filtering is provided at the water outlet.

[0008] Furthermore, the flocculant adder is also provided with a primary filter for preliminary filtration of the Yellow River water.

[0009] Furthermore, the bottom of the shell is in a conical shape, and the sand separator is in a date-core spindle shape and is located at the bottom conical structure of the shell.

[0010] Furthermore, the direction of the water inlet is along the tangent direction of the shell.

[0011] Furthermore, the shell is provided with a water channel which facilitates the water inlet direction at the water inlet to be along its tangent direction and form a spiral water flow.

[0012] Furthermore, a device housing for integrating all devices is also provided.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In the present invention, the Yellow River water first passes through a flocculant adding device to add flocculant to the Yellow River water, and then is pressurized by a booster pump and pumped into a water-sand separator. The Yellow River water entering the water-sand separator forms a spiral water flow along the tangent direction of the separator, and the silt in the Yellow River water is deposited at the bottom by the action of centrifugal force and enters a sedimentation and stratification tank, and is deposited below the stratification screen through screening by a stratification screen. As the liquid level of the Yellow River water in the water-sand separator continues to increase, the Yellow River water infiltrates the filter material, and the flocs and microbial colloids in the Yellow River water are filtered through the filter material, and clear water overflows from a drain outlet, thereby completing the water-sand separation and filtration of the Yellow River water; the filter material after filtering the flocs and microbial colloids is deposited into the sedimentation and stratification tank together with the silt separated from the Yellow River water, and is filtered out by a stratification screen. The sieving of the layered screen makes it deposit on the top of the layered screen, and is extracted by a pump. During the extraction process, the floccules are washed by air and water, and enter the filter material washing pool for sufficient aeration, and then fully stirred and rubbed in the stirring tank to wash the floccules and microbial colloids from the filter material, and the floccules and microbial colloids are connected and discharged together with the washed Yellow River water through the floc discharge pipe, and the washed filter material enters the filter material deposition tank under the action of its own gravity to be deposited and continuously added to the water-sand separator, so as to form the reuse of the filter material; at the same time, the electromagnetic valve is opened to discharge the separated and deposited silt from the silt discharge pipe, and the silt in the Yellow River water is separated and discharged. After the silt is discharged, the electromagnetic valve is closed to repeat the separation and deflocculation of the Yellow River water. The present invention effectively reduces the space occupied by the Yellow River water treatment, reduces the production input cost, improves the efficiency of the Yellow River water treatment, and provides a favorable guarantee for the drip irrigation of the Yellow River water irrigation area.

DETAILED DESCRIPTION

[0018] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The embodiments of the present invention include but are not limited to the following embodiments.

[0019] like Figure 1 As shown:

[0020] An integrated water-sand separation device for the Yellow River water is used to quickly and effectively separate the sediment, floccules, and microbial colloids in the Yellow River water, so that it can meet the water source requirements of drip irrigation, reduce the space and time required for the sedimentation of the Yellow River water, and improve the efficiency and effect of the Yellow River water treatment. Its specific structure includes a flocculant adder 1, on which an inlet for the Yellow River raw water and a flocculant addition port are provided. The Yellow River raw water enters the flocculant adder 1, and flocculants are added through the flocculant addition port, which facilitates the separation and deposition of microbial colloids and floccules in the Yellow River water; in order to preliminarily filter the Yellow River water and filter out the larger impurities therein, a primary filter is also provided at the front end of the flocculant adder 1 at the Yellow River raw water inlet position, and the impurities in the Yellow River raw water are preliminarily filtered through the primary filter.

[0021] The Yellow River water with flocculant added is pressurized by the booster pump 2 and pumped into the water-sand separator 3 to separate the water and sand in the Yellow River water, as well as the microbial colloid and floccules, and the clean water is discharged to meet the needs of the Yellow River water drip irrigation. Specifically, the water-sand separator 3 includes a shell 4, which is the external support structure of the water-sand separator 3. The shell 1 is provided with a water inlet 5, which is connected to the booster pump 2. The pressurized Yellow River water enters the water-sand separator from the water inlet 5; in order to better separate the water and sand of the Yellow River water entering the water inlet 5, the setting direction of the water inlet 5 in the shell 4 is along the tangent direction of the shell. At the same time, in order to further realize that the Yellow River water can be pumped out along the tangent direction of the shell after entering the shell 4, a water diversion channel 18 is provided in the shell 4, and the water diversion channel 18 enables the Yellow River water entering the shell to flow in a spiral shape along the inner wall of the shell.

[0022] A filter material 6 and a sand separator 7 are arranged in the shell 4. The filter material 6 is composed of larger particles such as quartz sand and is used to absorb microbial colloids and floccules retained in the water of the Yellow River. The sand separator 7 is arranged in the lower part of the shell 4. The bottom of the shell 4 is arranged in a conical structure. Correspondingly, the sand separator 7 is arranged in the shape of a jujube spindle. The sand separator is arranged at the position of the conical structure at the bottom of the shell 4. The sand separator 7 is welded to the inner wall of the shell through three foot points, and the remaining part is spaced a certain distance from the shell, usually about three centimeters, to achieve the "hourglass" structural characteristics; a sand discharge port 15 is arranged at the bottom of the shell 4, and a sedimentation and stratification tank 17 is arranged below the sand discharge port 15. The sedimentation and stratification tank 17 is provided with a stratified screen. 20, the particle size of the filter material is larger than the particle size of the sediment in the Yellow River water. After the Yellow River water enters the shell 4, it rushes out at high speed under the drainage action of the water diversion channel 18, and flows in a spiral manner in the shell 4. The sediment therein is deposited under the action of centrifugal force and gravity and enters the sedimentation and stratification tank 17 together with the filter material. The filter material 6 with a larger particle size is deposited on the upper part of the stratified screen 20, and the separated sediment with a smaller particle size is deposited on the lower part of the stratified screen 20; a sediment discharge pipe 21 is provided on the sedimentation and stratification tank 17, the inlet position of the sediment discharge pipe 21 is located at the lower part of the stratified screen 20, and an electromagnetic valve 22 is provided on the sediment discharge pipe 21, and the discharge of sediment from the sediment discharge pipe is controlled by opening and closing the electromagnetic valve 22.

[0023] The housing 4 is provided with a drain port 14. After the silt in the Yellow River water flows in a spiral manner and settles at the bottom and enters the sedimentation and stratification tank 17, the Yellow River water can only pass through the filter material 6 due to the closure of the electromagnetic valve 22, so that the liquid level continues to rise. The drain port 14 is arranged above the housing 4. The rising Yellow River water is separated from the silt and the filter material 6 filters and absorbs the microbial colloid and floccules therein to become usable clean water and overflow from the drain port 14. In order to further ensure that the Yellow River water overflowing from the drain port can have a better treatment effect, an overflow device 16 is arranged at the position of the drain port 14. The overflow device has the function of filtering. The overflow device 16 is equivalent to an extra layer of filtering structure, so that the filtering effect is better. When the silt in the housing 4 is deposited to a certain extent, the electromagnetic valve 22 is opened, and the separated and deposited silt in the sedimentation and stratification tank 17 is discharged from the silt discharge pipe 21.

[0024] In order to achieve the reuse of the filter material 6 in the shell 4 and maintain a good filtering effect, a suction pipe 8 is set on the sedimentation and stratification tank 17. The inlet position of the suction pipe 8 is located on the upper part of the stratification screen 20. The suction pipe 8 is connected to the suction pump 9. The suction pump 9 is started to extract the filter material adsorbed with microbial colloid and floc from the upper part of the sedimentation and stratification tank 17 through the suction pipe 8 for cleaning to achieve its reuse. In order to further realize the operation continuity of the whole device, a filter material washing tank 10 is arranged above the shell 4, and the filter material 6 extracted by the extraction pump is discharged into the filter material washing tank 10. In the process of extracting the material, due to the continuous flushing of water flow and air and the mutual friction between the filter materials, the microbial colloid and flocs on the filter material are separated from the filter material, and then enter the filter material washing tank for sufficient aeration; a stirring tank 11 is arranged below the filter material washing tank 10, and the filter material that has been fully aerated enters the stirring tank 11 for sufficient stirring, further causing the filter materials to collide and rub against each other, so that the microbial colloid and flocs are separated from the filter material 6, and at the same time, a floc discharge pipe 13 is arranged in the middle and lower part of the stirring tank 11, and the floc discharge pipe 13 discharges the microbial colloid and flocs together with the Yellow River water in the stirring tank. It is connected with the sediment discharge pipe 21 to facilitate the unified disposal of excrement, and the filter material with a larger mass density is deposited at the bottom of the stirring tank 11 under the action of gravity. At the same time, a filter material deposition tank 12 is arranged below the stirring tank 11, and the deposited filter material 6 enters the filter material deposition tank 12. The filter material deposition tank 12 is connected with the shell body, and the filter material in the shell body is replenished by flushing the deposited filter material in the filter material deposition tank 12, and this cycle is repeated to achieve the regeneration and reuse of the filter material.

[0025] In order to facilitate the installation and integration of the entire equipment, all of the above-mentioned equipment are integrated in a device housing 19; at the same time, in order to facilitate the control of the above-mentioned power equipment, a corresponding electric control box 23 is set for control. The electric control box 23 is implanted with an intelligent chip (such as STM32, etc.). The corresponding start-up and shutdown time intervals are set through the electric control box 23 to control the opening and closing time of the solenoid valve 22 to realize the intelligent and continuous operation of the equipment.

[0026] The above embodiment is only one of the preferred implementation modes of the present invention and should not be used to limit the protection scope of the present invention. Any changes or modifications that are made to the main design concept and spirit of the present invention and have no substantive significance, and the technical problems they solve are still consistent with the present invention, should be included in the protection scope of the present invention.
