Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to sewage purification equipment for industrial sewage treatment. Background Art

[0002] Industrial wastewater includes production wastewater and production sewage, which refers to the wastewater and waste residue produced in the industrial production process. The existing industrial wastewater treatment equipment treats wastewater and waste residue through flocculants and sedimentation to achieve the purpose of purifying water sources, so as to facilitate the reuse of water resources.

[0003] There are many existing technologies for industrial wastewater purification devices, such as: Chinese patent announcement No. CN118005160B discloses a flocculation purification device for sewage treatment, including a base, a flocculation mechanism, a water inlet pipe and a drug delivery assembly. Among them, two support frames are horizontally spaced apart on the top of the base. The flocculation mechanism includes a sedimentation assembly, a control assembly, a drive assembly and a steering assembly. The sedimentation assembly is located between the two support frames and is rotatably connected to the two support frames, and the sedimentation assembly has a stirring assembly. The control assembly is arranged on the outside of the support frame and is fixed on the base. The drive assembly cooperates with the control assembly to drive the stirring assembly. The steering assembly can drive the sedimentation assembly to pitch around the support frame. The water inlet pipe can deliver sewage into the mixing chamber. The drug delivery assembly can deliver flocculant to the mixing chamber.

[0004] It can be seen that the existing industrial wastewater purification equipment is usually connected to industrial equipment. When the industrial wastewater is treated, the wastewater is mixed with the flocculant, so that the impurities (such as heavy metals) in the wastewater are precipitated at the bottom, which causes the impurities to accumulate at the bottom of the tank. When the industrial wastewater produced by the industrial equipment has poor water quality, the impurities in the tank will accumulate quickly, resulting in the need to clean the tank frequently. However, during the cleaning process, the industrial equipment needs to be shut down, and then the tank needs to be opened and the impurities at the bottom of the tank need to be cleaned, which affects the continuous operation of the industrial equipment. Summary of the invention

[0005] The object of the present invention is to provide a sewage purification device for industrial sewage treatment to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention aims to provide a sewage purification device for industrial sewage treatment, including a tank body, a liquid storage chamber, and an aggregate chamber. The upper end of the liquid storage chamber is connected to the liquid inlet, and the upper end of the aggregate chamber is connected to the feeding port. The tank body has a drainage bin inside, and a siphon mechanism is arranged in the drainage bin. The siphon mechanism is used to intercept the sewage in the drainage bin and separate the sewage from the sediment when the sewage reaches a preset discharge volume. The siphon mechanism has a buffer component on the outside to limit the sewage in the drainage bin to delay the time for the sewage to enter the siphon mechanism. The liquid inlet is located directly above the buffer component, and a valve mechanism is arranged below the buffer component to separate the drainage bin from the aggregate chamber. In the process of adding sewage into the drainage bin, the impact force of the sewage is used to push the buffer component to guide the sewage into the upper drainage chamber and precipitate it. After the siphon mechanism discharges the sewage, the buffer component moves upward to trigger the valve mechanism, so that the impurities precipitated at the bottom of the drainage bin fall into the aggregate chamber, thereby realizing the centralized collection of impurities.

[0007] As a further improvement of the technical solution, the drainage tank includes an upper drainage chamber and a lower drainage chamber, both of which are provided with a siphon mechanism. The lower drainage chamber is used to receive sewage transported from the upper drainage chamber and transport the received sewage to the outside of the tank body. When the sewage flows into the lower drainage chamber, the siphon mechanism in the lower drainage chamber intercepts the sewage to prolong the time the sewage stays in the lower drainage chamber. An upper drainage pipe is arranged at the bottom of the upper drainage cavity and one side of the lower drainage cavity to connect the two, and a lower drainage pipe is arranged at the bottom end of the lower drainage cavity to connect the lower drainage cavity with the tank body drainage port.

[0008] As a further improvement of the present technical solution, a liquid injection mechanism is fixedly arranged at the bottom of the liquid storage chamber and close to the end of the upper drain pipe, the liquid injection mechanism includes a liquid injection pipe connected to the liquid storage chamber, connecting rods are rotatably connected on both sides of the liquid injection pipe, a baffle plate for blocking the liquid inside the liquid injection pipe is fixedly connected to the bottom of the connecting rod, and a counterweight ball located on the drainage path at the end of the upper drain pipe is fixedly connected to the bottom of the baffle plate.

[0009] As a further improvement of the technical solution, a stopper for limiting the reverse rotation of the connecting rod is fixedly provided on the outer ring of the injection pipe. Under normal conditions, the stopper is close to the upper drain pipe and fits with the connecting rod.

[0010] As a further improvement of the present technical solution, the siphon mechanism includes a sleeve with an opening facing downward at the bottom and a closed top, and a sleeve extending from the sleeve opening into the sleeve. The bottom of the sleeve located in the upper drainage chamber is fixedly connected to the upper drainage pipe, and the sleeve and the upper drainage pipe are communicated with each other. The bottom of the sleeve located in the lower drainage chamber is fixedly connected to the lower drainage pipe, and the sleeve is communicated with the lower drainage pipe. When discharging sewage, a drainage channel for sewage to flow through is formed between the sleeve and the sleeve.

[0011] As a further improvement of the present technical solution, the buffer component includes a buffer plate which is sleeved on the outside of the sleeve and slidably connected to the inner wall of the upper drainage chamber, and a tension spring elastically connected between the upper surface of the buffer plate and the inner wall of the upper drainage chamber. The buffer plate divides the interior of the upper drainage chamber into a buffer area and a discharge area. One side of the upper drainage chamber located below the buffer plate protrudes outward and forms a liquid guide groove for sewage to flow through.

[0012] As a further improvement of the technical solution, a fixed block is fixedly arranged on the outside of the sleeve, and the fixed block is higher than the lower edge of the liquid guide groove in the horizontal direction to limit excessive downward movement of the buffer plate. The height of the fixed block in the horizontal direction is higher than the top end of the sleeve.

[0013] As a further improvement of the technical solution, an aggregate block with a triangular cross-section is fixedly arranged at the bottom of the upper drainage chamber, and the top of the aggregate block has an inclined surface inclined toward its central axis, which is used to guide impurities in the sewage to the middle.

[0014] As a further improvement of the present technical solution, the valve mechanism is a valve plate slidably connected to the bottom of the upper drainage chamber, the valve plate has a plurality of through grooves for unloading, and the bottom of the upper drainage chamber corresponding to the through grooves has a plurality of discharge grooves. Under normal circumstances, the discharge grooves and the through grooves are in an overlapping state, and the valve plate is slidably connected on both sides with slide rails fixed to the bottom of the upper drainage chamber. One end of the valve plate is elastically connected to the bottom of the upper drainage chamber with a return spring, and the other end is fitted with a vertical rod that passes through the bottom of the upper drainage chamber and the aggregate block. The upper end of the vertical rod is a vertical end and the top is fixedly connected to the buffer plate, and the bottom is inclined outward to be a bent end.

[0015] As a further improvement of the present technical solution, the buffer component also includes a piston rod fixedly connected to the buffer plate, and the piston rod is sleeved with a shell fixedly connected to the inner wall of the upper drainage chamber, and the shell is provided with an inlet pipe and an exhaust pipe, and both the inlet pipe and the exhaust pipe are provided with a one-way valve, wherein the inlet pipe passes through the tank body and is connected to the outside, the one-way valve in the inlet pipe is used for allowing external air to enter the shell, and the one-way valve in the exhaust pipe is used for allowing air in the shell to be discharged, and the inner diameter of the inlet pipe is larger than the inner diameter of the exhaust pipe, so that when the buffer plate moves upward, the time for the buffer plate to move up is delayed.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the sewage purification equipment for industrial sewage treatment, when the sewage impact force on the buffer plate is weakened and cannot overcome the elastic potential energy of the tension spring, the sewage in the discharge area is gradually discharged through the siphon effect, and the buffer plate is pulled upward in the opposite direction under the elastic action of the tension spring, and the valve plate slides from the vertical end of the vertical rod to the bent end, and the through groove and the discharge groove are changed from misalignment to a conducting state, so that the industrial equipment can realize automatic discharge of impurities without stopping the machine, thereby reducing the labor intensity.

[0017] 2. In the sewage purification equipment for industrial sewage treatment, when the impact of the sewage disappears, the connecting rod is restricted from rotating in the opposite direction by a block, so as to prevent the counterweight ball from rotating in the opposite direction and causing excessive flocculant to be added into the lower drainage chamber, thereby causing waste.

[0020] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0022] like Figure 1 and Figure 2 As shown, a sewage purification device for industrial sewage treatment is provided, including a tank body 100, a liquid storage chamber 113, and a collection chamber 114. The upper end of the liquid storage chamber 113 is connected to a liquid inlet 115, and the upper end of the collection chamber 114 is connected to a feeding port 116. The tank body 100 has a drainage chamber 110 inside, and a siphon mechanism 120 is arranged inside the drainage chamber 110. The siphon mechanism 120 is used to intercept the sewage in the drainage chamber 110 and separate the sewage from the sediment when the sewage reaches a preset discharge volume. The siphon mechanism 120 has a buffer member 140 outside to limit the sewage in the drainage chamber 110, so as to extend the discharge of the sewage. To slow down the time when sewage enters the siphon mechanism 120, the liquid inlet 115 is located directly above the buffer member 140, and a valve mechanism 150 is provided below the buffer member 140 to separate the drainage bin 110 from the collecting chamber 114. In the process of sewage being added into the drainage bin 110, the impact force of the sewage is used to push the buffer member 140 to guide the sewage into the upper drainage chamber 111 and settle. After the siphon mechanism 120 discharges the sewage, the buffer member 140 moves upward to trigger the valve mechanism 150, so that the impurities settled at the bottom of the drainage bin 110 fall into the collecting chamber 114, thereby realizing the centralized collection of impurities.

[0023] The drainage chamber 110 includes an upper drainage chamber 111 and a lower drainage chamber 112, each of which is provided with a siphon mechanism 120. The lower drainage chamber 112 is used to receive sewage transported from the upper drainage chamber 111 and transport the received sewage to the outside of the tank body 100. When the sewage flows into the lower drainage chamber 112, the siphon mechanism 120 in the lower drainage chamber 112 intercepts the sewage to extend the time the sewage stays in the lower drainage chamber 112. Next, an upper drainage pipe 117 is provided at the bottom of the upper drainage chamber 111 and one side of the lower drainage chamber 112 to connect the two, and a lower drainage pipe 112a is provided at the bottom end of the lower drainage chamber 112 to connect the lower drainage chamber 112 with the drainage port of the tank body 100.

[0024] As mentioned above, after the sewage is first injected into the upper drainage chamber 111, it first passes through the upper drainage chamber 111 to achieve the first sedimentation. When the amount of sewage added reaches the discharge volume preset by the siphon mechanism 120, the sewage in the upper drainage chamber 111 is discharged into the lower drainage chamber 112 through the upper drainage pipe 117 under the action of the siphon mechanism 120. At this time, the sewage is secondary precipitated and purified in the lower drainage chamber 112. Similar to the siphon mechanism 120 in the upper drainage chamber 111, after the sewage in the lower drainage chamber 112 reaches the corresponding discharge volume, the sewage flows from the lower drainage pipe 112a to the outside of the tank body 100.

[0025] In order to improve the clarity and overall water quality of the wastewater discharged from the lower drain pipe 112a, based on the above diagram and combined with Figure 7 As shown, a liquid injection mechanism 130 is fixedly arranged at the bottom of the liquid storage chamber 113 and near the end of the upper drain pipe 117. The liquid injection mechanism 130 includes a liquid injection pipe 131 connected to the liquid storage chamber 113, and connecting rods are rotatably connected to both sides of the liquid injection pipe 131. A baffle 132 for blocking the liquid inside the liquid injection pipe 131 is fixedly connected to the bottom of the connecting rod, and a counterweight ball 133 located on the drainage path at the end of the upper drain pipe 117 is fixedly connected to the bottom of the baffle 132. In this way, when the sewage is discharged from one end of the upper drainage pipe 117, the kinetic energy of the sewage impacts the counterweight ball 133. The impact force generated by the sewage pushes the counterweight ball 133 to rotate counterclockwise with the connecting rod as the center. As the rotation amplitude of the baffle 132 increases, the baffle 132 rotates and tilts and separates from the bottom end of the injection tube 131. The injection tube 131 is connected. At this time, the flocculant in the liquid storage chamber 113 can be discharged into the lower drainage chamber 112 through the injection tube 131 and mixed with the sewage in the lower drainage chamber 112.

[0026] Due to the impact force of the sewage, the sewage is in a state of back and forth agitation when it is rushed into the lower drainage chamber 112, so that the sewage and the flocculant in the liquid storage chamber 113 can be fully mixed, thereby improving the mixing effect between the two and improving the overall water quality discharged from the lower drainage pipe 112a.

[0027] In addition, considering that after the impact of the sewage disappears, the counterweight ball 133 will rotate clockwise under the action of inertia, the flocculant in the injection pipe 131 will be injected into the lower drainage chamber 112 again. That is to say, when there is no sewage passing through the upper drainage pipe 117, the reverse rotation of the counterweight ball 133 will cause excessive flocculant to be added to the lower drainage chamber 112, thereby causing waste. Therefore, a stopper 134 for limiting the reverse rotation of the connecting rod is fixedly provided on the outer ring of the injection pipe 131. Under normal conditions (when the connecting rod is in a vertical state), the stopper 134 is close to the upper drainage pipe 117 and fits with the connecting rod.

[0028] Furthermore, when wastewater is injected into the upward drainage chamber 111 and the impurities are first precipitated, the specific structure of the siphon mechanism 120 is first described. Figure 2 The figure further discloses the structure of the siphon mechanism 120, which includes a sleeve 121 with an opening facing downward at the bottom and a closed top, and a sleeve 122 extending from the opening of the sleeve 121 into the sleeve 121. The bottom of the sleeve 122 located in the upper drainage chamber 111 is fixedly connected to the upper drainage pipe 117, and the sleeve 122 and the upper drainage pipe 117 are communicated with each other. The bottom of the sleeve 122 located in the lower drainage chamber 112 is fixedly connected to the lower drainage pipe 112a, and the sleeve 122 is communicated with the lower drainage pipe 112a. When discharging sewage, a drainage channel for sewage to flow through is formed between the sleeve 121 and the sleeve 122.

[0029] On the other hand, when sewage is injected into the upper drainage cavity 111, the sewage will first contact the buffer member 140. Figure 2 Based on and combined with Figure 3 and Figure 5 As shown, the specific structure of the buffer 140 is shown, wherein the buffer 140 includes a buffer plate 141 which is sleeved on the outside of the sleeve 121 and slidably connected to the inner wall of the upper drainage chamber 111, and a tension spring 142 which is elastically connected between the upper surface of the buffer plate 141 and the inner wall of the upper drainage chamber 111. The buffer plate 141 divides the interior of the upper drainage chamber 111 into a buffer area and a discharge area, wherein the buffer area is above the buffer plate 141 and the discharge area is below the buffer plate 141, and one side of the upper drainage chamber 111 located below the buffer plate 141 protrudes outward and forms a liquid guide groove 111a for sewage to flow through. In this way, the impact force of the added sewage overcomes the elastic potential energy of the tension spring 142 to push the buffer plate 141 downward. When the upper surface of the buffer plate 141 moves downward to be lower than the upper edge of the liquid guide groove 111a in the horizontal direction, the sewage flows through the liquid guide groove 111a to the discharge area below the buffer plate 141, and when the sewage has not reached the preset drainage volume, it settles and remains still in the upper drainage chamber 111.

[0030] In addition, a fixed block 121a is fixedly arranged outside the sleeve 121, and the fixed block 121a is higher than the lower edge of the liquid guide groove 111a in the horizontal direction to limit the excessive downward movement of the buffer plate 141, and the height of the fixed block 121a in the horizontal direction is higher than the top of the sleeve 122. It can be seen that when the buffer plate 141 drops to contact with the fixed block 121a, the fixed block 121a can not only limit the buffer plate 141 from continuing to move downward, but also keep the sewage flowing smoothly from the buffer zone to the discharge zone at this time, and the position of the fixed block 121a is higher than the top of the sleeve 122 so that the water level between the sleeve 121 and the upper drainage chamber 111 is higher than the top of the sleeve 122, so as to form a siphon effect.

[0031] After the sewage in the upper drainage chamber 111 is allowed to stand for the first time, impurities are deposited and left to stand at the bottom of the upper drainage chamber 111. In order to gather the impurities at the bottom of the upper drainage chamber 111, a triangular aggregate block 118 is fixedly provided at the bottom of the upper drainage chamber 111. The top of the aggregate block 118 has an inclined surface inclined toward its axis, which is used to guide the impurities in the sewage to the middle part for centralized cleaning later. Moreover, when the sewage enters the discharge area next time, the sewage can also be used to flush the impurities remaining on the inclined surface of the aggregate block 118, so that the impurities are gathered in the middle part. Working principle: When the upper surface of the buffer plate 141 moves to the lower edge of the liquid guiding groove 111a, the sewage flows from the buffer zone to the discharge area for standing. During this process, the valve mechanism 150 is in a closed state, and the water level of the sewage rises in the discharge area. When the sewage rises to exceed the upper edge of the sleeve 122, a siphon effect is generated. The sewage in the discharge area is separated from the impurities after the first sedimentation, and the sewage flows into the lower drainage chamber 112 through the sleeve 122 and the upper drainage pipe 117. After the sewage passes through the end of the upper drainage pipe 117, the flocculant in the liquid storage chamber 113 will be released so that it can be fully mixed with the sewage to improve the overall water quality.

[0032] In order to ensure that the industrial equipment can still clean the impurities inside the tank 100 without stopping, Figure 2 , Figure 4 Combined with Figure 6 As shown, the specific structure of the valve mechanism 150 is shown. The valve mechanism 150 is a valve plate 151 slidably connected to the bottom of the upper drainage chamber 111. The valve plate 151 has a plurality of through slots 152 for material discharge. The bottom of the upper drainage chamber 111 corresponding to the through slots 152 has a plurality of material discharge slots 119. Under normal conditions, the material discharge slots 119 and the through slots 152 are in a coincident state. On the other hand, the two sides of the valve plate 151 are slidably connected with slide rails 154 fixed to the bottom of the upper drainage chamber 111. One end of the valve plate 151 is elastically connected to the bottom of the upper drainage chamber 111 with a return spring 153, and the other end is attached with a vertical rod 143 that penetrates the bottom of the upper drainage chamber 111 and the aggregate block 118. The upper end of the vertical rod 143 is a vertical end and the top is fixedly connected to the buffer plate 141, and the bottom is tilted outwards as a bent end.

[0033] Specifically during operation: when the sewage on the buffer plate 141 reaches the preset discharge volume, the impact force of the sewage is used to overcome the elastic potential energy of the tension spring 142 and push the buffer plate 141 downward, and the valve plate 151 slides from the bent end of the vertical rod 143 to the vertical end, so that the through groove 152 and the discharge groove 119 are changed from the on state to the closed state. This process is a water storage sedimentation process. On the contrary, when the impact force of the sewage on the buffer plate 141 is weakened and cannot overcome the elastic potential energy of the tension spring 142, the sewage in the discharge area is gradually discharged through the siphon effect, and the buffer plate 141 is pulled upward in the opposite direction under the elastic action of the tension spring 142. The valve plate 151 slides from the vertical end of the vertical rod 143 to the bent end, and the through groove 152 and the discharge groove 119 are changed from the misalignment to the on state, so that the industrial equipment can realize the automatic discharge of impurities without stopping the machine, thereby reducing the labor intensity. This process is a impurity removal process.

[0034] Furthermore, in order to ensure the smooth progress of the siphon effect and avoid the buffer plate 141 rising above the upper edge of the liquid guide groove 111a before the siphon effect ends, the buffer member 140 also includes a piston rod 144 fixedly connected to the buffer plate 141, and the piston rod 144 is sleeved with a shell 145 fixedly connected to the inner wall of the upper drainage chamber 111, and the shell 145 is provided with an air inlet pipe and an exhaust pipe, and both the air inlet pipe and the exhaust pipe are provided with a one-way valve 146, wherein the air inlet pipe passes through the tank body 100 and is connected to the outside, the one-way valve 146 in the air inlet pipe is used to allow external air to enter the shell 145, and the one-way valve 146 in the exhaust pipe is used to discharge the air in the shell 145, and the inner diameter of the air inlet pipe is larger than the inner diameter of the exhaust pipe, and when the buffer plate 141 moves upward, the time for the buffer plate 141 to move upward is delayed.

[0035] In this way, when the piston rod 144 performs vertical reciprocating motion, the buffer plate 141 will drive the piston rod 144 to reciprocate. During the downward movement of the piston rod 144, the piston rod 144 inhales gas into the outer shell 145 through the one-way valve 146 in the air inlet pipe. During the upward movement of the piston rod 144, the piston rod 144 slowly discharges the gas in the outer shell 145 through the exhaust pipe. When the injection of sewage into the upward drainage chamber 111 is stopped, the upward movement speed of the buffer plate 141 is delayed to ensure the smooth implementation of the siphon effect.

[0036] Finally, the cover plate on one side of the bottom of the tank body 100 is opened, and the impurities in the collecting cavity 114 are cleaned manually, and the purified sewage can be passed into the fine filtering device for more refined purification.

[0037] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
