Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a solid-liquid separation device for wastewater treatment. Background Art

[0002] Wastewater treatment is the use of physical, chemical and biological methods to treat wastewater, purify the wastewater, reduce pollution, and even recycle and reuse wastewater to make full use of water resources.

[0003] Generally, common wastewater treatment first uses physical treatment methods to remove insoluble suspended pollutants in the wastewater, such as plastic bag garbage, water-insoluble particles and other substances, and then uses chemical or biological methods to treat the physically treated wastewater to remove harmful substances in the wastewater and obtain usable water. In the wastewater treatment process, whether physical, chemical or biological methods are used, larger solid wastes must be removed first to ensure the smooth progress of subsequent treatment. However, existing equipment is prone to clogging during the filtration process and requires manual cleaning, which is not only time-consuming and labor-intensive, but also inefficient. Therefore, we need to find more efficient and complete equipment and technologies to solve this problem in order to improve the efficiency and effectiveness of wastewater treatment.

[0004] In the prior art, a Chinese patent with a publication number of CN215518702U is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: it includes a body, a water inlet pipe is fixedly arranged on one side of the body, and a first filter mechanism, a second filter mechanism and a third filter mechanism are arranged in sequence from left to right inside the body. Both sides of the first filter mechanism, the second filter mechanism and the third filter mechanism are movably arranged with the body through a slider, and a connecting plate is arranged inside the body. The solid-liquid separation device for wastewater treatment is provided with a first filter mechanism, a second filter mechanism and a third filter mechanism, and the wastewater to be treated is transported from the water inlet pipe to the inside of the body. Under the action of the first filter net, the second filter net and the third filter net, the wastewater is filtered layer by layer, and the solid impurities or floating objects in the wastewater are filtered, thereby achieving solid-liquid separation. However, when the wastewater contains garbage with a large area such as plastic bags and rags, it is very easy to cause blockage. Summary of the invention

[0005] The purpose of the utility model is to provide a solid-liquid separation device for wastewater treatment to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A solid-liquid separation device for wastewater treatment comprises a box body; a water inlet is arranged on the top of the box body, a filter chamber is arranged inside the box body, a filter mechanism is arranged in the filter chamber, and the filter mechanism is used to filter out larger impurities and garbage in the wastewater; a waste box is fixedly connected to one side of the box body, and the waste box is communicated with the filter mechanism; a filter plate is arranged below the filter mechanism, a collection chamber is arranged below the filter plate, a water outlet is arranged on one side of the collection chamber, and the water outlet is connected to an external water pump.

[0008] When performing solid-liquid separation, wastewater is input from the water inlet at the upper end of the box. The water inlet is connected to the filter mechanism, so the wastewater enters the filter mechanism through the water inlet. The larger waste and garbage in the wastewater are filtered through the filtering action of the filter mechanism to prevent the larger waste and garbage from clogging the filter equipment during the subsequent filtering process. After being filtered by the filter mechanism, the garbage and waste enter the waste box for collection, and are destroyed uniformly after collection. The wastewater filtered by the filter mechanism is further filtered by the filter plate to remove impurity particles in the wastewater, and then enters the collection chamber, and the separated wastewater is pumped out from the outlet through an external water pump.

[0009] A further improvement of the technical solution of the utility model is that: a connecting pipe is fixedly connected below the waste box, a first filter screen is arranged in the connecting pipe, and the connecting pipe is connected with the waste box and the filter chamber.

[0010] The above technical solution is adopted, in which a connecting pipe is set up and a first filter net is provided in the connecting pipe. After the waste enters the waste box, it accumulates in the waste box. Excess water passes through the connecting pipe under the action of gravity. Under the action of the first filter net, the waste will be blocked to prevent the waste from falling into the filter chamber.

[0011] A further improvement of the technical solution of the utility model is that a second filter screen is provided at the water outlet.

[0012] The above technical solution is adopted, in which a second filter screen is set up, the pore size of the second filter screen is smaller, and the wastewater in the filter chamber is pumped out by the suction force of the water pump. Fine impurities are filtered by the second filter screen and retained in the collection chamber, so that the discharged wastewater contains almost no impurity particles.

[0013] A further improvement of the technical solution of the utility model is that the filter plate is slidably connected to the box body, and a handle is provided on one side of the filter plate.

[0014] The above technical solution is adopted. In this solution, a sliding connection is set between the filter plate and the box body. When the filtering effect of the filter plate is poor, the filter plate can be taken out by pulling the handle, and the filter plate can be replaced and then replaced with a new one, thereby improving the efficiency of the device.

[0015] A further improvement of the technical solution of the utility model is that: the filtering mechanism includes a collecting barrel, the collecting barrel is fixedly connected to the box body, a first leakage hole is cut on the surface of the collecting barrel, a push plate is provided inside the collecting barrel, and the radius of the push plate is the same as the radius of the inner wall of the collecting barrel; a movable end of an electric push rod is fixedly connected to one side of the push plate, and the fixed end of the electric push rod is fixed to a side of the collecting barrel close to the water inlet.

[0016] The above technical solution is adopted. At this time, the electric push rod is started. By setting the electric push rod, the electric push rod pushes the push plate to push the waste and garbage collected in the collection bucket into the waste bucket, thereby collecting the waste and garbage, and the wastewater leaks into the filter chamber through the first leakage hole.

[0017] A further improvement of the technical solution of the utility model is that the filtering mechanism includes a collecting barrel, an auger is provided in the collecting barrel, an end of the box body close to the water inlet is fixedly connected to a support platform, a motor is fixedly connected to the support platform, the motor shaft is fixedly connected to the auger, and the end of the auger away from the water inlet extends into the waste box.

[0018] The above technical solution is adopted, in which the motor is started, the motor starts to run, and then drives the auger to rotate. The waste and garbage in the wastewater then fall into the gap between the auger blades and move with the rotation of the auger. Since one end of the auger extends to the waste box, the waste and garbage are finally sent to the waste box, thereby realizing the collection of waste and garbage. In addition, the auger will squeeze the waste and garbage during the rotating transportation process to squeeze out the water therein, thereby preventing too much water from being entrained in the waste.

[0019] A further improvement of the technical solution of the utility model is that: the filter plate comprises a clamping plate, an activated carbon plate is arranged inside the clamping plate, and the activated carbon plate is loaded with activated carbon powder and biological sludge.

[0020] The above technical solution is adopted, in which activated carbon treatment can be used together with the activated sludge method, which is a biological sewage treatment method that converts organic matter in sewage into inorganic matter through a series of biochemical reactions, thereby purifying the water body. This method mixes sludge containing microorganisms with sewage. In the presence of oxygen, the microorganisms consume organic matter for growth and metabolism, and finally convert it into water and inorganic matter. This method can treat large amounts of sewage efficiently and energy-savingly, and can be operated in places with small spaces. Powdered activated carbon is used in this process. Powdered activated carbon can adsorb substances that are toxic to microorganisms and are eventually collected with the sludge.

[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0022] 1. The utility model provides a solid-liquid separation device for wastewater treatment. By setting a filtering mechanism, large particles of waste and garbage are collected by the filtering mechanism and discharged into a collection box for collection first, and then through multi-stage filtration, the solid-liquid separation of the wastewater is more sufficient, and serious blockage will not occur, thereby improving the use efficiency.

[0023] 2. The utility model provides a solid-liquid separation device for wastewater treatment, which is provided with a motor and an auger; the motor is started, the motor starts to run, and then the auger is driven to rotate. Waste and garbage in the wastewater then fall into the gap between the auger blades and move with the rotation of the auger. Since one end of the auger extends to the waste bin, the waste and garbage are finally sent to the waste bin, thereby realizing the collection of waste and garbage. In addition, the auger will squeeze the waste and garbage during the rotating transportation process to squeeze out the water therein, thereby preventing the waste from carrying too much water.

[0024] 3. The utility model provides a solid-liquid separation device for wastewater treatment. A connecting pipe is provided and a first filter is arranged in the connecting pipe. After the waste enters the waste box, it is accumulated in the waste box. The excess water passes through the connecting pipe under the action of gravity. Under the action of the first filter, the waste will be blocked to prevent the waste from falling into the filter chamber. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The present invention is further described in detail below in conjunction with the embodiments:

[0034] Example 1

[0035] like Figure 1-5 As shown, the utility model provides a solid-liquid separation device for wastewater treatment, comprising a box body 1; a water inlet 2 is provided on the top of the box body 1, a filter chamber 20 is provided inside the box body 1, a filter mechanism is provided in the filter chamber 20, and the filter mechanism is used to filter out larger impurities and garbage in the wastewater; a waste box 4 is fixedly connected to one side of the box body 1, and the waste box 4 is communicated with the filter mechanism; a filter plate 5 is provided below the filter mechanism, a collection chamber 6 is provided below the filter plate 5, a water outlet 7 is provided on one side of the collection chamber 6, and the water outlet 7 is connected to an external water pump.

[0036] In this embodiment, when performing solid-liquid separation, wastewater is input from the water inlet 2 at the upper end of the box body 1. The water inlet 2 is connected to the filtering mechanism, so the wastewater enters the filtering mechanism through the water inlet 2. Through the filtering action of the filtering mechanism, larger waste and garbage in the wastewater are filtered to prevent the larger waste and garbage from clogging the filtering equipment during the subsequent filtering process.

[0037] The garbage and waste are filtered by the filtering mechanism and then enter the waste bin 4 for collection, and are destroyed after collection. The waste water filtered by the filtering mechanism is further filtered by the filter plate 5 to remove the impurity particles in the waste water, and then enters the collection chamber 6, and the separated waste water is pumped out from the water outlet 7 by an external water pump.

[0038] In this embodiment, preferably, a connecting pipe 17 is fixedly connected below the waste box 4 , and a first filter screen is arranged in the connecting pipe 17 ; the connecting pipe 17 is connected to the waste box 4 and the filter chamber 20 .

[0039] The waste and garbage filtered out by the filtering mechanism may contain some waste water, which will cause certain pollution if it is discharged directly with the waste without treatment. By setting a connecting pipe 17 and providing a first filter screen in the connecting pipe 17, the waste enters the waste box 4 and accumulates in the waste box 4. Excess water passes through the connecting pipe 17 under the action of gravity. Under the action of the first filter screen, the waste will be blocked to prevent the waste from falling into the filter chamber 20.

[0040] Preferably, a second filter screen 19 is provided at the water outlet 7 .

[0041] When performing solid-liquid separation, the capacity of the collection chamber 6 is limited, so an external water pump is required to absorb the liquid in the collection chamber 6 after filtration. When the water pump is extracting, a second filter screen 19 is set. The pore size of the second filter screen 19 is smaller. The suction force of the water pump extracts the wastewater in the filter chamber 20, and fine impurities are filtered by the second filter screen 19 and retained in the collection chamber 6, so that the discharged wastewater contains almost no impurity particles. The harmful components in the water are removed through subsequent treatment to obtain pure water.

[0042] Preferably, the filter plate 5 is slidably connected to the housing 1 , and a handle 14 is provided on one side of the filter plate 5 .

[0043] The filter plate 5 may be clogged with impurities after multiple filtrations. By setting a sliding connection between the filter plate 5 and the housing 1, when the filtering effect of the filter plate 5 is poor, the filter plate 5 can be taken out by pulling the handle 14, and the filter plate 5 can be replaced and then replaced with a new one, thereby improving the efficiency of the device.

[0044] Example 2

[0045] like Figure 6 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the filtering mechanism includes a collecting barrel 8, the collecting barrel 8 is fixedly connected to the box body 1, a first leakage hole 9 is cut on the surface of the collecting barrel 8, a push plate 10 is provided inside the collecting barrel 8, and the radius of the push plate 10 is the same as the radius of the inner wall of the collecting barrel 8; a movable end of an electric push rod 18 is fixedly connected to one side of the push plate 10, and the fixed end of the electric push rod 18 is fixed to the side of the collecting barrel 8 close to the water inlet 2.

[0046] In this embodiment, waste water flows into the collection barrel 8 from the water inlet 2. Since the collection barrel 8 is provided with a first leakage hole 9, large particles of waste and garbage cannot pass through the leakage hole, so they accumulate in the collection barrel 8, and the waste water flows through the leakage hole to the filter chamber 20. At this time, the electric push rod 18 is started, and the electric push rod 18 pushes the push plate 10 to push the waste and garbage accumulated in the collection barrel 8 into the waste barrel, so as to collect the waste and garbage, and the waste water leaks into the filter chamber 20 through the first leakage hole 9.

[0047] Example 3

[0048] like Figure 5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the filtering mechanism includes a collecting barrel 8, an auger 11 is provided in the collecting barrel 8, an end of the box body 1 close to the water inlet 2 is fixedly connected to a support platform 12, a motor 13 is fixedly connected to the support platform 12, a rotating shaft of the motor 13 is fixedly connected to the auger 11, and the auger 11 extends from the end of the water inlet 2 to the waste bin 4.

[0049] In this embodiment, wastewater flows into the collection barrel 8 from the water inlet 2. Since the collection barrel 8 is provided with a first leakage hole 9, large particles of waste and garbage cannot pass through the leakage hole, so they accumulate in the collection barrel 8, and the wastewater flows to the filter chamber 20 through the leakage hole. At the same time, the motor 13 is started, and the motor 13 starts to run, thereby driving the auger 11 to rotate. The waste and garbage in the wastewater then fall into the gap between the blades of the auger 11 and move with the rotation of the auger 11. Since one end of the auger 11 extends to the waste bin 4, the waste and garbage are finally sent to the waste bin 4, thereby realizing the collection of waste and garbage. In addition, the auger 11 will squeeze the waste and garbage during the rotating transportation process to squeeze out the water therein, thereby preventing too much water from being entrained in the waste.

[0050] Example 4

[0051] On the basis of Example 1, the utility model provides a technical solution: preferably, the filter plate 5 includes a clamping plate 15, an activated carbon plate 16 is arranged inside the clamping plate 15, and the activated carbon plate 16 is loaded with activated carbon powder and biological sludge.

[0052] In this embodiment, activated carbon treatment can be used together with the activated sludge process, which is a biological method for treating sewage. Through a series of biochemical reactions, organic matter in sewage is converted into inorganic matter, thereby purifying the water body. This method mixes sludge containing microorganisms with sewage. In the presence of oxygen, the microorganisms consume organic matter for growth and metabolism, and eventually convert it into water and inorganic matter. This method can treat large amounts of sewage efficiently and energy-savingly, and can be operated in places with small spaces. Powdered activated carbon is used in this process. Powdered activated carbon can adsorb substances that are toxic to microorganisms and are eventually collected with the sludge.

[0053] The working principle of the solid-liquid separation device for wastewater treatment is described in detail below.

[0054] like Figure 1-5As shown, when performing solid-liquid separation, wastewater is input from the water inlet 2 at the upper end of the housing 1, the water inlet 2 is connected to the filtering mechanism, and the wastewater enters the housing 1 through the water inlet 2, and the motor 13 is started, and the motor 13 starts to run, thereby driving the auger 11 to rotate. Waste and garbage in the wastewater then fall into the gap between the blades of the auger 11 and move with the rotation of the auger 11. Since one end of the auger 11 extends to the waste bin 4, the waste and garbage are finally sent to the waste bin 4, thereby realizing the collection of waste and garbage. In addition, the auger 11 will also squeeze the waste and garbage during the rotating transportation process to squeeze out the water therein, thereby preventing the waste from carrying too much water. The garbage and waste are filtered by the filtering mechanism and then enter the waste bin 4 for collection, and are uniformly destroyed after the collection is completed; the wastewater filtered by the filtering mechanism is further filtered by the filter plate 5 to remove the impurity particles in the wastewater, and then enters the collection chamber 6, and the separated wastewater is pumped out from the water outlet 7 by an external water pump.

[0055] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
