Description

Technical Field

[0001] The invention relates to the technical field of water treatment, and in particular to an energy-saving industrial circulating water treatment device. Background Art

[0002] Industrial circulating water refers to water used in industrial production processes that is recycled after treatment, such as cooling circulating water, equipment circulating water, etc. Its main purpose is to save water resources, reduce costs and reduce emissions. During the long-term circulation of industrial circulating water, due to continuous evaporation, the salts in the water are concentrated. In addition, the cooling water is in contact with the atmosphere, and the dissolved oxygen and bacteria content increase. There will be different degrees of inorganic salt deposition and adhesion, metal corrosion, and bacterial algae microbial growth, resulting in reduced heat exchange efficiency of heat exchange equipment, pipeline blockage, system corrosion and other consequences. Therefore, it is necessary to treat industrial circulating water.

[0003] The commonly used treatment method is to add flocculants to the circulating water. The colloids and dispersed particles of the suspended matter in the circulating water form flocs under the interaction of molecular forces, and they collide and condense with each other during the sedimentation process. Their size and mass continue to increase. When the flocs grow to a certain volume, they separate from the water phase under the action of gravity to form a lower sedimentation layer. The upper clear water layer is then introduced into the industrial circulation equipment through the outlet pipe for use. For example, the patent document with the announcement number CN209065628U discloses a modular integrated circulating water treatment device, including a sedimentation tank, a filtration tank and a disinfection tank. A dosing port is provided at the upper end of the sedimentation tank, a motor is provided on the right side of the dosing port, and a rotating shaft is provided at the output end of the motor, and the rotating shaft extends into the sedimentation tank.

[0004] When treating circulating water, the above-mentioned circulating water treatment device adds flocculants into the dosing port, and the motor drives the rotating shaft to rotate to mix the flocculants with the circulating water. After the colloids and dispersed particles of the suspended matter in the circulating water form flocs, they fall to the bottom of the sedimentation tank under their own gravity, forming an upper water layer and a lower sludge layer. The sludge in the lower layer can be discharged through the sewage outlet, and the upper water layer is collected and processed before being recycled again. However, since the circulating water in the sedimentation tank is flowing, the flocculants are not fully mixed with the circulating water after being added, and may flow into the filter tank for filtration before forming flocs, resulting in unsatisfactory flocculation and sedimentation effects of the circulating water, thereby affecting the treatment effect of the circulating water. Summary of the invention

[0005] In view of this, the present invention provides an energy-saving industrial circulating water treatment device to solve the technical problem that after the reagent is added into the flowing circulating water, it is not fully mixed with the circulating water, resulting in unsatisfactory flocculation and sedimentation effect of the circulating water.

[0006] In order to solve the above technical problems, the present invention provides an energy-saving industrial circulating water treatment device, comprising a reaction pool provided with a dosing port, a stirring mechanism arranged in the reaction pool, and a sedimentation tank connected to the reaction pool, wherein the reaction pool comprises a reaction pool 1 and a reaction pool 2 arranged in the reaction pool 1, and the reaction pool 1 and the reaction pool 2 are alternately connected to the sedimentation tank;

[0007] One side of the sedimentation tank is the water inlet end, and the other side is the water outlet end. A connecting frame is slidably connected in the sedimentation tank. A linear driver for driving the connecting frame to move is provided on one side of the sedimentation tank. Multiple partitions are installed at intervals near the water inlet end of the connecting frame. Multiple inclined plates are installed at intervals below the partition in the sedimentation tank. The up and down sliding of the partition allows the partition to be inserted into the gap between two adjacent inclined plates and the inclined plate can be inserted into the gap between two adjacent partitions.

[0008] By adopting the above technical scheme, reaction tank one and reaction tank two alternately supply water to the sedimentation tank, which prolongs the reaction time of the reagent and the circulating water, is beneficial to fully mix the reagent and the circulating water, and improves the flocculation effect. At the same time, partition plate one and inclined plate one are arranged to further mix the circulating water and the reagent during the flow process, which is beneficial to improve the flocculation effect of the circulating water, and can also slow down the impact force of the water flow, reduce the floating of the sediment at the bottom of the sedimentation tank, and is beneficial to improve the sedimentation effect. Specifically, reaction tank one and reaction tank two are used to mix reagents and circulating water, and reaction tank one and reaction tank two alternately supply water to the sedimentation tank. For example, when reaction tank one is in a state of supplying water to the sedimentation tank, the circulating water enters reaction tank two and mixes with the reagent. When the water in reaction tank one is transported to the sedimentation tank, the circulating water in reaction tank two and the reagent are mixed. Then reaction tank two is in a state of supplying water to the sedimentation tank, and the circulating water enters reaction tank one and mixes with the reagent. Such alternating circulation can not only keep the sedimentation tank in a continuous water inflow state, but also prolong the reaction time of the reagent and the circulating water in reaction tank one or reaction tank two, which is conducive to the full mixing of the reagent and the circulating water. The linear drive drives the connecting frame to move upward, leaving a gap between the lower end surface of the partition one and the upper end surface of the inclined plate one. The mixed water enters the water inlet end of the sedimentation tank and passes through the gap between two adjacent partitions and the gap between two adjacent inclined plates one in turn. The partition one and the inclined plate one are staggered to further mix the circulating water and the reagent during the flow, which is beneficial to improving the flocculation effect of the circulating water. At the same time, it can slow down the impact force of the water flow, reduce the floating of the sediment at the bottom of the sedimentation tank, and is beneficial to improving the sedimentation effect.

[0009] Preferably, a delivery pipeline is installed below reaction tank one and reaction tank two, and the end of the delivery pipeline is connected to a water distribution tank. The water distribution tank is located in the sedimentation tank near the water inlet end, and a plurality of water outlets are provided on the side of the water distribution tank. An electromagnetic valve is installed on the delivery pipeline to control the alternating connection between reaction tank one and reaction tank two and the sedimentation tank.

[0010] By adopting the above technical scheme, the water in reaction tank one and reaction tank two after reacting with the reagent enters the sedimentation tank through the conveying pipe, the solenoid valve controls the reaction tank one and reaction tank two to be alternately connected with the sedimentation tank, the water in the conveying pipe enters the water distribution tank, and reaches the sedimentation tank through multiple water outlets, which can slow down the impact force of the water flow, reduce the floating of the sediment at the bottom of the sedimentation tank, and is beneficial to improving the sedimentation effect.

[0011] Preferably, a plurality of partition plates 2 are installed at intervals on the connecting frame, and the partition plates 2 extend from a position close to the water outlet end to a position close to the partition plate 1. A plurality of inclined plates 2 are installed at intervals below the sedimentation tank and located below the partition plates 2. The up and down sliding of the partition plates 2 enables the partition plates 1 to be inserted into the gap between two adjacent inclined plates 2 and the inclined plates 2 to be inserted into the gap between two adjacent partition plates 2. A baffle is also installed between the inclined plates 1 and 2.

[0012] By adopting the above technical solution, the linear drive drives the connecting frame to move upward, so that a gap is left between the lower end surface of the partition two and the upper end surface of the inclined plate two. The water flowing out from the gap of the inclined plate one passes through the baffle plate and passes through the gap between the two adjacent inclined plates two, the gap between the inclined plate two and the partition two in turn, and then is discharged from the water outlet. The partition two and the inclined plate two block the suspended matter in the water, which is beneficial to improving the cleanliness of the discharged water. The linear drive drives the connecting frame to move downward, and the connecting frame drives partition one and partition two to move downward, so that partition one is inserted into the gap between two adjacent inclined plates one, and inclined plate one is inserted into the gap between two adjacent partition ones. Partition one can scrape off the sediment on the surface of inclined plate one, and inclined plate one can scrape off the sediment on the surface of partition one. Similarly, partition two is inserted into the gap between two adjacent inclined plates two, and inclined plate two is inserted into the gap between two adjacent partition twos. Partition two can scrape off the sediment on the surface of inclined plate two, and inclined plate two can scrape off the sediment on the surface of partition two, which helps to clean partition one, partition two, inclined plate one and inclined plate two, reduce the blockage of the gaps therebetween, and allow water to flow smoothly.

[0013] Preferably, partition 1, inclined plate 1, partition 2 and inclined plate 2 are all inclined, a slide groove is inclined on the inner wall of the sedimentation tank, and a slide rod 1 that can slide in the slide groove is fixedly connected to the connecting frame.

[0014] By adopting the above technical solution, the water flows through the gap between two adjacent partition plates 1, the gap between two adjacent inclined plates 1, the gap between two adjacent inclined plates 2, and the gap between inclined plate 2 and partition plate 2 in sequence. The partition plates 1, slanted plate 1, partition plate 2 and inclined plate 2 are all inclined to increase the stroke of the water flow, which is beneficial to the full mixing of the reagent and the circulating water and to the blocking of suspended matter on the surface of the water body after flocculation, thereby improving the water quality.

[0015] Preferably, the upper end surfaces of the inclined plate 1 and the inclined plate 2 are both herringbone shaped.

[0016] By adopting the above technical solution, the upper end surfaces of inclined plate 1 and inclined plate 2 are both herringbone-shaped, which reduces the accumulation of sediment scraped off partitions 1 and 2 and helps the sediment to fall into the sedimentation tank.

[0017] Preferably, a plurality of water outlet holes are provided on the side wall of the sedimentation tank at the water outlet end, and a water outlet trough is provided below the water outlet holes.

[0018] By adopting the above technical solution, the water flowing out from the gap between the inclined plate 2 and the partition plate 2 flows into the water outlet trough through the water outlet hole, so as to be easily transferred to the next processing process.

[0019] Preferably, a water baffle plate capable of blocking the water outlet is slidably arranged in the sedimentation tank, a guide groove is arranged on the sedimentation tank, a guide member capable of sliding in the guide groove is connected to the lower part of the water baffle plate, a bending groove is arranged on the upper part of the connecting frame, and a slide rod capable of sliding in the bending groove is arranged on the upper part of the baffle plate; a sewage outlet is opened on the side wall of the sedimentation tank adjacent to the water outlet, and the connecting frame drives the water baffle plate to descend so that the water baffle plate blocks the water outlet, and the water level in the sedimentation tank rises so that suspended matter on the water surface can be discharged through the sewage outlet.

[0020] By adopting the above technical solution, when it is necessary to clean partition one, inclined plate one, partition two and inclined plate two, the linear drive drives the connecting frame to descend, the bending groove presses down the slide bar two, so that the water baffle moves downward, and the guide part of the water baffle slides downward along the guide groove. The water baffle blocks the water outlet, the water level in the sedimentation tank rises, and the suspended matter on the water surface is discharged through the sewage outlet, which helps to improve the water quality.

[0021] Preferably, a screw is provided above the connecting frame, a screw slider is provided on the screw, a push plate is fixedly connected to the screw slider and can push the suspended matter on the water surface toward the side close to the sewage outlet, and a driving motor that can drive the screw to rotate is installed on one side of the sedimentation tank.

[0022] By adopting the above technical solution, after the linear drive drives the connecting frame to descend, the water baffle blocks the water outlet, the water level in the sedimentation tank rises, the drive motor is started, the drive motor drives the screw to rotate, and the screw slider drives the push plate to move. The push plate pushes the suspended matter on the water surface to the sewage outlet and discharges it through the sewage outlet, which helps to improve the water quality.

[0023] The beneficial effects of the above technical solution of the present invention are as follows:

[0024] 1. The reaction tank 1 and the reaction tank 2 of the present invention alternately supply water to the sedimentation tank, prolonging the reaction time of the reagent and the circulating water, which is conducive to the full mixing of the reagent and the circulating water and improving the flocculation effect. At the same time, the partition plate 1 and the inclined plate 1 are arranged to further mix the circulating water and the reagent during the flow process, which is conducive to improving the flocculation effect of the circulating water, and can slow down the impact force of the water flow, reduce the floating of the sediment at the bottom of the sedimentation tank, and help improve the sedimentation effect.

[0025] 2. The water flowing out from the gap between two adjacent inclined plates 1 passes through the baffle plate in turn through the gap between two adjacent inclined plates 2, the gap between inclined plate 2 and partition 2, and then is discharged from the water outlet. Partition 2 and inclined plate 2 block the suspended matter in the water, which is beneficial to improve the cleanliness of the discharged water; the linear drive drives the connecting frame to move downward, and the connecting frame drives partition 1 and partition 2 to move downward, so that partition 1 is inserted into the gap between two adjacent inclined plates 1, inclined plate 1 is inserted into the gap between two adjacent partitions 1, partition 2 is inserted into the gap between two adjacent inclined plates 2, and inclined plate 2 is inserted into the gap between two adjacent partitions 2, which is helpful to clean partition 1, partition 2, inclined plate 1 and inclined plate 2, reduce the blockage of the gaps between them, and allow the water to pass smoothly.

[0026] 3. After the linear drive drives the connecting frame to descend, the water baffle blocks the water outlet, the water level in the sedimentation tank rises, and the drive motor is started.

DETAILED DESCRIPTION

[0036] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be combined with the embodiments of the present invention. Figure 1-Figure 8 , the technical scheme of the embodiment of the present invention is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0037] Example

[0038] This embodiment provides an energy-saving industrial circulating water treatment device, such as Figure 1 As shown, it includes a reaction tank 1, a sedimentation tank 3 and a stirring mechanism 2.

[0039] like Figure 1 As shown, the reaction pool 1 includes a reaction pool 11 and a reaction pool 2 12 disposed in the reaction pool 1 11 , and both the reaction pool 1 11 and the reaction pool 2 12 are provided with a drug addition port and a water inlet.

[0040] like Figure 1 As shown, the stirring mechanism 2 includes a stirring frame 1 21 , a stirring frame 22 and a driving unit 23 .

[0041] like Figure 1 As shown, the stirring frame 1 21 is arranged between the reaction pool 1 11 and the reaction pool 2 12, and the stirring frame 2 22 is arranged in the reaction pool 2 12. A connecting piece 24 is connected between the stirring frame 1 21 and the stirring frame 2 22, so that the driving unit 23 drives the stirring frame 2 22 to rotate while realizing the synchronous rotation of the stirring frame 1 21 and the stirring frame 2 22. The stirring of the stirring frame 1 21 and the stirring frame 2 22 is conducive to the full mixing of the circulating water and the reagent in the reaction pool 1 11 and the reaction pool 2 12. The driving unit 23 is driven by a motor, which is a prior art and will not be described in detail.

[0042] like Figure 1 As shown, the sedimentation tank 3 is arranged below the reaction tank 1 11, and a sewage pipe 33 is arranged below the sedimentation tank 3. A delivery pipe 4 is installed below the reaction tank 1 11 and the reaction tank 2 12, and one end of the delivery pipe 4 is provided with two branch pipes, which are respectively connected to the reaction tank 1 11 and the reaction tank 2 12, and the other end of the delivery pipe 4 extends into the sedimentation tank 3. The circulating water mixed with the reagent in the reaction tank 1 11 and the reaction tank 2 12 is delivered to the sedimentation tank 3 through the delivery pipe 4.

[0043] like Figure 1 and Figure 2 As shown, solenoid valves 41 are installed on both branches, and the solenoid valves 41 are interconnected with the controller signal. When one solenoid valve 41 is opened, the other solenoid valve 41 is closed, so that the reaction pool 1 11 and the reaction pool 2 12 alternately supply water to the sedimentation pool 3. For example, when the reaction pool 1 11 is in the state of supplying water to the sedimentation pool 3, the circulating water enters the reaction pool 2 12 and mixes with the reagent. When the water in the reaction pool 1 11 is transported to the sedimentation pool 3, the circulating water in the reaction pool 2 12 is mixed with the reagent. Then the reaction pool 2 12 is in the state of supplying water to the sedimentation pool 3, and the circulating water enters the reaction pool 1 11 and mixes with the reagent. Such alternating circulation can not only make the sedimentation pool 3 in a continuous water inflow state, but also prolong the reaction time of the reagent in the reaction pool 1 11 or the reaction pool 2 12 and the circulating water, which is conducive to the full mixing of the reagent and the circulating water.

[0044] like Figure 1 As shown, one side of the sedimentation tank 3 is the water inlet end 31, and the other side is the water outlet end 32. The end of the delivery pipe 4 extending into the sedimentation tank 3 is connected to a water distribution tank 42, and the water distribution tank 42 is located in the sedimentation tank 3 near the water inlet end 31. Figure 6 As shown, a plurality of water outlets 43 are provided on the side of the water distribution tank 42. The water reaches the sedimentation tank 3 through the plurality of water outlets 43, which can reduce the impact of the water flow, reduce the floating of the sediment at the bottom of the sedimentation tank 3, and help improve the sedimentation effect.

A plurality of inclined plates 56 are installed at intervals below the sedimentation tank 3 at the lower part of the partition plates 55. The up and down sliding of the partition plates 55 enables the partition plates 1 53 to be inserted into the gap between two adjacent inclined plates 2 56 and the inclined plates 2 56 to be inserted into the gap between two adjacent partition plates 2 55. A baffle plate 57 is also installed between the inclined plates 1 54 and 56. The length of the baffle plate 57 in the up and down direction is greater than the length of the inclined plates 1 54 and 56 in the up and down direction.

Similarly, the partition 2 55 is inserted into the gap between two adjacent inclined plates 2 56, and the inclined plate 2 56 is inserted into the gap between two adjacent partitions 2 55. The partition 2 55 can scrape off the sediment on the surface of the inclined plate 2 56, and the inclined plate 2 56 can scrape off the sediment on the surface of the partition 2 55, which helps to clean the partition 1 53, the partition 2 55, the inclined plate 1 54 and the inclined plate 2 56, reduce the blockage of the gaps therebetween, and allow the water to pass smoothly.

[0050] like Figure 3 As shown, baffle 1 53, inclined plate 1 54, baffle 2 55 and inclined plate 2 56 are all inclined to increase the stroke of the water flow, which is beneficial to the full mixing of the reagent and the circulating water and to the blocking of suspended matter on the surface of the water body after flocculation, thereby helping to improve the water quality.

[0051] like Figure 3 and Figure 5 As shown, the upper end surfaces of the inclined plate 1 54 and the inclined plate 2 56 are both herringbone-shaped, which reduces the accumulation of sediments scraped off the partition 1 53 and the partition 2 55 and helps the sediments fall into the sedimentation tank 3.

[0052] like Figure 3 and Figure 4 As shown, a plurality of water outlet holes 34 are provided on the side wall of the sedimentation tank 3 at the water outlet end 32, and a water outlet trough 35 is provided below the water outlet holes 34. The water flowing out from the gap between the inclined plate 2 56 and the partition 2 55 flows into the water outlet trough 35 through the water outlet holes 34, so as to be easily transferred to the next treatment process. The linear drive 59 drives the connecting frame 5 to move upward, and a gap is left between the lower end surface of the partition 2 55 and the upper end surface of the inclined plate 2 56. At this time, the water outlet holes 34 are located near the position of two-thirds from the lower end to the upper end of the partition 2 55, and the water level inside the sedimentation tank 3 is also close to this position.

[0053] like Figure 3 and Figure 4As shown, a water baffle 58 capable of blocking the water outlet 34 is slidably provided in the sedimentation tank 3, and the linear driver 59 drives the connecting frame 5 to slide up and down, thereby driving the water baffle 58 to slide up and down, so that the water baffle 58 opens or closes the water outlet 34.

The height of the sewage outlet 36 is greater than the height of the water outlet 34. After the connecting frame 5 drives the water baffle 58 to descend, the water baffle 58 blocks the water outlet 34, and the water level in the sedimentation tank 3 rises, so that the suspended matter on the water surface can be discharged through the sewage outlet 36.

The solenoid valve 41 on the conveying pipeline 4 controls the reaction pool 1 11 and the reaction pool 2 12 to alternately supply water to the sedimentation tank 3;

[0060] Step 2: After the water in the delivery pipe 4 reaches the water distribution tank 42, it reaches the sedimentation tank 3 through multiple water outlets 43, and passes through the gap between two adjacent partition plates 1 53 and the gap between two adjacent inclined plates 1 54 in sequence, and then passes through the baffle 57, and then passes through the gap between two adjacent inclined plates 2 56, the gap between the inclined plate 2 56 and the partition 2 55 in sequence, and flows into the water outlet trough 35 through the water outlet hole 34, so as to be transferred to the next treatment process;

[0061] Step 3: When it is necessary to clean the partition 1 53, the inclined plate 1 54, the partition 2 55 and the inclined plate 2 56, the linear drive 59 drives the connecting frame 5 to move downward, and the connecting frame 5 drives the partition 1 53 and the partition 2 55 to move downward, so that the partition 1 53 is inserted into the gap between two adjacent inclined plates 1 54, and the inclined plate 1 54 is inserted into the gap between two adjacent partitions 1 53. The partition 1 53 can scrape off the sediment on the surface of the inclined plate 1 54, and the inclined plate 1 54 can scrape off the sediment on the surface of the partition 1 53. Similarly, the partition 2 55 is inserted into the gap between two adjacent inclined plates 2 56, and the inclined plate 2 56 is inserted into the gap between two adjacent partitions 2 55. The partition 2 55 can scrape off the sediment on the surface of the inclined plate 2 56, and the inclined plate 2 56 can scrape off the sediment on the surface of the partition 2 55;

[0062] Step 4: After the linear drive 59 drives the connecting frame 5 to descend, the water baffle 58 blocks the water outlet 34, the water level in the sedimentation tank 3 rises, and the drive motor 63 is started. The drive motor 63 drives the lead screw 6 to rotate, so that the lead screw slider 61 drives the push plate 62 to move, and the push plate 62 pushes the suspended matter on the water surface to the sewage outlet 36 and discharges it through the sewage outlet 36. The sediment under the sedimentation tank 3 is discharged through the sewage pipe 33.
