Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a water resource filter pool. Background Art

[0002] Water is a commonly used resource in daily life and industrial production. In order to improve the safety and convenience of people's water use, water treatment plants usually purify and disinfect water resources to produce water that meets the corresponding standards for people's life and production. Domestic water is mainly drawn from rivers, lakes, groundwater, and surface water through the water plant's water intake pump station. The water plant is treated by sedimentation, disinfection, filtration and other process flows in accordance with the "National Sanitary Standards for Drinking Water", and finally delivered to each user through a water distribution pump station. In the process of treating water, the water is usually filtered through filter media to remove impurities in the water. After multiple filtration processes, the filter media usually contains more impurities, so the filter media needs to be cleaned regularly to ensure the cleanliness of the filter media.

[0003] For example, the patent document with application number 2019220451420 discloses a light filter media filter, which includes a filter body and a filter media layer located in the filter body. The light filter media filter also includes: a water supply and drainage channel, which is located at the bottom of the filter body, connected to the water inlet well via a first water inlet valve, and connected to a backwash wastewater discharge siphon via a flushing valve. In the filtration stage, the water supply and drainage channel supplies raw water to the filter media layer, and in the backwash stage, it discharges the backwash wastewater. The backwash wastewater is discharged to the backwash wastewater pool via the backwash wastewater discharge siphon; the backwash wastewater discharge siphon is configured to utilize the siphon effect to discharge the backwash wastewater from the water supply and drainage channels to the backwash wastewater discharge siphon; a siphon destruction system is connected to the backwash wastewater discharge siphon and configured to introduce air into the backwash wastewater discharge siphon when the liquid level in the pool during the backwash stage is lower than the top height of the backwash wastewater discharge siphon, thereby destroying the siphon effect of the backwash wastewater discharge siphon and stopping backwash drainage.

[0004] Although the above technical scheme can be used to clean the filter media in the filter tank, in order to ensure the filtering effect of the filter media on water, it is usually necessary to lay thicker and various types of filter media in the filter tank to filter the water. When the above technical scheme cannot be cleaned, the filter media is only backwashed by flushing, so that the filter media are stacked and piled up on each other during the flushing process, which makes it easy for flushing dead corners to appear in the filter media, resulting in impurities in the filter media cannot be effectively cleaned during the backwashing process, resulting in long-term accumulation of impurities in the filter media, affecting the filtering effect of the filter media on water. Utility Model Content

[0005] The utility model aims to provide a water resource filter material pool to solve the technical problem in the prior art that impurities in the filter material cannot be effectively cleaned during the backwashing process, thus affecting the filtering effect of the filter material on water.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a water resource filter pool, including a filter body and a backwashing device, a filter layer is provided in the conveying filter body, and the filter layer is used to filter water; the backwashing device includes a backwashing pipe, the water outlet end of the backwashing pipe is connected to the bottom of the filter body, and the water inlet end of the backwashing pipe is connected to the side wall of the filter body, and the backwashing pipe is used to extract water in the filter body to flush the filter layer; the backwashing device also includes a vibrating member, and the vibrating member is used to drive the filter layer to vibrate during the flushing process.

[0007] The principle and advantage of this scheme are: before filtering water, water is transported to the filter tank body, and the filter material in the filter tank is flushed through the backwashing device. After the flushing is completed, the backwashing device is closed, and the water in the filter tank body is filtered through the filter material and then output. When flushing the filter material, the vibrating element in the backwashing device drives the filter material in the filter material layer to vibrate, thereby realizing the displacement of the filter material during the flushing process.

[0008] In this solution, when flushing the filter material layer in the filter material pool, the backwashing water is input from the bottom of the filter pool body, so that the filter material can move upward under the push of the water pressure output by the backwashing device during the flushing process, and move downward under the action of gravity, so that the filter material can move continuously during the flushing process, and the cleaning effect of the filter material is improved. In addition, by setting a vibration part in the backwashing device to drive the filter material to vibrate continuously during the flushing process, the movement of the filter material during the flushing process is improved, and the flushing dead angle in the filter material layer is reduced. At the same time, by vibrating the filter material, the filter materials can rub against each other during the flushing process, further improving the flushing effect of the filter material and improving the cleanliness of the filter material after flushing.

[0009] Preferably, as an improvement, the filter body is provided with an input port and an output port, the input port is located at the bottom of the filter body, and the input port is used to input the water to be filtered into the filter body; the output port is located at the side wall of the filter body close to one end of the top of the filter body, and the output port is used to output the water in the filter body. When filtering the water to be filtered, the water to be filtered can spread upward from the bottom of the filter body to pass through the filter material layer to complete the filtering process, avoiding the water to be filtered from flowing from top to bottom under the action of gravity. The flow speed is too fast, and the contact time between the water to be filtered and the filter material in the filter material layer is too short, which affects the filtering effect of the filter material layer on the water to be filtered.

[0010] Preferably, as an improvement, a three-way valve is provided on the output port, the input end of the three-way valve is connected to the output port, the output end of the three-way valve is connected to the output pipe and the backwash pipe respectively, and the three-way valve is used to control the flow direction of water during water filtration or backwashing, so that the output port of the filter body can adjust the flow direction of water according to the working conditions of filtration and flushing, and ensure the normal flow of water in the filter body under different conditions.

[0011] Preferably, as an improvement, a gate is provided on the output port, and the gate is used to control the opening and closing size of the output port, so that the output port of the filter body can be adjusted according to the filtering and flushing state, ensuring that the flow rate of the output port of the filter body matches the actual demand.

[0012] Preferably, as an improvement, the filter material layer includes multiple filter material sub-layers, and the multiple filter material sub-layers are stacked and distributed in the height direction in the filter tank body; a partition net is provided between the filter material sub-layers, and the partition net is used to separate adjacent filter material sub-layers. By stacking a variety of filter materials, the fineness of filtration of the water to be filtered can be improved under the action of multiple filter materials. And by providing a partition net between the filter material sub-layers, the filter material in the filter material sub-layer can maintain a stable position during the filtration and flushing process, avoiding the mutual mixing of the filter materials under the impact of the water flow during the filtration and flushing process, which affects the layered filtration effect of the filter material.

[0013] Preferably, as an improvement, the interval between two adjacent layers of separation nets is greater than the thickness of the filter material sublayer between the separation nets, so that the filter material in the filter material sublayer has sufficient movement space during the flushing process, thereby improving the friction effect of the filter material during the flushing process.

[0014] Preferably, as an improvement, the vibrating member includes a plurality of vibrating members connected to the partition net, and the vibrating member is used to drive the partition net to vibrate. By driving the partition net to vibrate, the filter material laid on the partition net can vibrate under the drive of the partition net during the flushing process, ensuring that the filter material in each area can vibrate, thereby improving the flushing effect of the filter material.

[0015] Preferably, as an improvement, the partition net is further provided with a plurality of extension rods, which are evenly distributed on the partition net, so that during the flushing process, the extension rods can drive the filter material away from the partition net to vibrate, thereby ensuring the vibration frequency of the filter material in the height direction during the flushing process and improving the mutual friction effect of the filter material in different areas.

[0020] As attached Figure 1 With attached Figure 2 As shown, a water resource filter pool includes a filter pool body 1 and a backwashing device 3. A filter layer 2 is provided in the filter pool body 1. The filter layer 2 is used for filtering water resources. The backwashing device 3 is used for flushing the filter layer 2.

[0021] An input port and an output port are provided on the filter body 1, wherein the input port is located at the bottom of the filter body 1, and is connected to a water pipe 101, which is used to input water to be filtered into the filter body 1; the output port is located on the side wall of the filter body 1 near one end of the top of the filter body 1, and is connected to an output pipe 102, which is used to output the filtered water in the filter body 1. When filtering the water to be filtered, the water to be filtered can spread upward from the bottom of the filter body 1 through the filter material layer 2 to complete the filtering process, avoiding the water to be filtered from flowing from top to bottom under the action of gravity. The flow speed is too fast, and the contact time between the water to be filtered and the filter material in the filter material layer 2 is too short, which affects the filtering effect of the filter material layer 2 on the water to be filtered.

[0022] The filter material layer 2 is located at the bottom of the filter tank body 1, and the filter material layer 2 completely covers the bottom of the filter tank body 1. The filter material layer 2 includes multiple filter material sub-layers 201, and the multiple filter material sub-layers 201 are stacked and distributed in the height direction in the filter tank body 1. A separation net 202 is provided between each layer of filter material sub-layer 201, and the separation net 202 is used to separate the filter material of two adjacent layers, and the interval between the two adjacent layers of the separation net 202 is greater than the thickness of the filter material sub-layer 201 between the separation nets 202; wherein the filter material can be one of the water filtration materials such as quartz sand, gravel, granular activated carbon, etc. The specific parameters and distribution content of the filter material are prior art and will not be repeated here. By stacking a plurality of filter materials, the water to be filtered can improve the filtration fineness under the action of multiple filter materials. In addition, by setting a separation net 202 between the filter material sublayers 201, the filter material in the filter material sublayer 201 can maintain a stable position during the filtering and flushing process, avoiding the filter material from mixing with each other under the impact of water flow during the filtering and flushing process, thereby affecting the layered filtering effect of the filter material.

[0023] The backwashing device 3 includes a backwashing pipe 301, wherein the water outlet of the backwashing pipe 301 is connected to the bottom of the filter body 1, the water inlet of the backwashing pipe 301 is connected to the side wall of the filter body 1, the water inlet of the backwashing pipe 301 is used to extract water in the filter body 1, the water outlet of the backwashing pipe 301 is used to transport water to the filter body 1 to wash the filter material, and the water outlet of the backwashing pipe 301 is connected to multiple washing nozzles 4 through multiple water outlet branches, and the multiple washing nozzles 4 are evenly laid at the bottom of the filter body 1. A backwashing pump 302 and an air compressor 303 are connected to the backwashing pipe 301, the backwashing pump 302 is used to pressurize the water in the backwashing pipe 301, and the air compressor 303 is used to transport compressed air into the backwashing pipe 301. When in use, the water to be filtered is first delivered to the filter body 1 through the water delivery pipe 101. When the water level reaches a certain height, the water delivery pipe 101 is closed, and the water in the filter body 1 is pumped to the backwash pipe 301 through the backwash pump 302. The air compressor 303 delivers compressed air to the backwash pipe 301, so that the water in the backwash pipe 301 is mixed with the compressed air to form high-pressure water. The high-pressure water is input into the filter body 1 through one end of the backwash pipe 301 located at the bottom of the filter body 1 to clean the filter material at the bottom of the filter body 1. The filter material in the filter body 1 can be cleaned through the backwash system, ensuring that the filter material can be cleaned in time after filtering the water, avoiding the accumulation of impurities in the filter material, causing water pollution during the filtration process, and affecting the quality of the filtered water.

[0024] The backwash pipe 301 is also connected to a sewage pipe 5, one end of which is connected to the backwash pipe 301 through a valve, and the other end is connected to a sewage pool, and the sewage pipe 5 is used to discharge the sewage in the backwash pipe 301. After backwashing, the sewage in the backwash pipe 301 can be discharged in time under the action of the sewage pipe 5, so as to avoid the sewage from accumulating in the backwash pipe 301 and polluting the environment in the backwash pipe 301, resulting in secondary contamination of the filter material in the subsequent backwashing process, thereby affecting the flushing effect of the filter material.

[0025] The water inlet ends of the output pipe 102 and the backwash pipe 301 are both connected to the output port of the filter body 1. Specifically, a three-way valve 6 is connected to the output port. Specifically, in this embodiment, the three-way valve 6 is an electric diversion three-way regulating valve. The input end of the three-way valve 6 is connected to the output port. The two output ports are respectively connected to the output pipe 102 and the backwash pipe 301. The three-way valve 6 is used to control the flow direction of water during water filtration or backwashing. A gate plate 7 is also rotatably connected to the output port. Specifically, one side of the gate plate 7 is connected to the filter body 1 through a rotating shaft. The gate plate 7 is used to control the opening and closing size of the output port. The output port of the filter body 1 can adjust the size of the output port according to the filtering and flushing status to ensure that the flow rate of the output port of the filter body 1 matches the actual demand.

[0026] The backwashing device 3 also includes a vibrating member 8, which is used to drive the filter material to vibrate during the backwashing process, wherein the vibrating member 8 can be a vibration motor; specifically, the vibrating member 8 includes multiple vibrating members 8, and the multiple vibrating members 8 are distributed on the side wall of the filter body 1 corresponding to the positions of each partition net 202.

By driving the partition net 202 to vibrate, the filter material laid on the partition net 202 can be vibrated under the drive of the partition net 202 during the flushing process, ensuring that the filter material in each area can be vibrated, thereby improving the flushing effect of the filter material.

[0027] A plurality of extension rods 203 are also provided on each partition net 202, and the plurality of extension rods 203 are evenly distributed on the partition net 202. One end of the extension rod 203 is fixedly connected to the partition net 202 by a buckle or a bolt, and the other end extends upward in the height direction. The extension rod 203 is used to vibrate under the drive of the partition net 202 during the backwashing process, so as to stir the filter material in the filter material layer 2 during the backwashing process. In the flushing process, the extension rod 203 can drive the vibration of the filter material in the height direction, ensure the vibration frequency of the filter material in the height direction during the flushing process, and increase the mutual friction of the filter material in different areas.

[0028] The specific implementation process is as follows:

[0029] Before filtering the water, the water is transported to the filter tank body 1, and the filter material in the filter tank is flushed through the backwashing device 3. After the flushing is completed, the backwashing device 3 is closed, and the water in the filter tank body 1 is filtered through the filter material and then output. When flushing the filter material, the vibration element 8 in the backwashing device 3 drives the filter material in the filter material layer 2 to vibrate, thereby realizing the displacement of the filter material during the flushing process.

[0030] Compared with the prior art, in this solution, when flushing the filter material layer 2 in the filter material pool, the backwashing water is input from the bottom of the filter pool body 1, so that the filter material can move upward under the push of the water pressure output by the backwashing device 3 during the flushing process, and move downward under the action of gravity, so that the filter material can move continuously during the flushing process, and the cleaning effect of the filter material is improved. In addition, by setting a vibration member 8 in the backwashing device 3 to drive the filter material to vibrate continuously during the flushing process, the movement of the filter material during the flushing process is improved, and the flushing dead corners in the filter material layer 2 are reduced. At the same time, by vibrating the filter material, the filter materials can rub against each other during the flushing process, further improving the flushing effect of the filter material and improving the cleanliness of the filter material after flushing.

It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the technical solution of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
