Abstract

The present invention relates to an anti-clogging sewage rapid treatment vehicle, comprising a vehicle body, a grille machine and a hydraulic screen. The grille machine comprises a grille machine housing, a grille machine screen, a screen cylinder and a grille machine auger. The grille machine screen separates the grille machine housing into a filter chamber and a sewage chamber; the screen cylinder is located in the filter chamber and is driven by a first drive member and is connected to the grille machine feed port; the grille machine auger comprises a rotating shaft and spiral blades, driven by a second drive member and one end facing the grille machine discharge port; the hydraulic screen is connected to the grille machine. In the present invention, since the sewage has already removed large volumes of soft impurities when passing through the screen cylinder, the grille machine auger squeezes a mixture containing only fine particles, and the problem of impurities hanging on the grille machine auger will not occur.

Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment vehicles, and in particular to an anti-clogging sewage rapid treatment vehicle. Background Art

[0002] Sewage treatment can effectively treat domestic sewage, industrial wastewater, etc. in cities and prevent sewage and pollutants from flowing directly into water areas. It is of great significance to improving the ecological environment, enhancing the quality of cities and promoting economic development.

[0003] A sewage treatment vehicle is a special vehicle that can treat sewage on site. It can be parked next to a sewage pool, and after sucking the sewage into the filtering equipment on the vehicle body, the sewage is separated into clean water and solid waste on site. Specifically, the sewage is sucked into the screen machine for preliminary separation, and then flocculants are added and stirred and precipitated, and then the solid-liquid mixture after precipitation is separated into solid and liquid to obtain clean water that can be discharged and solid waste that can be used as waste.

[0004] In existing sewage treatment vehicles, the screen machine is generally equipped with an auger. Because of the existence of the auger, some impurities in the sewage, such as plastic bags and food residues, will be hung on the arc-shaped flange of the auger and cannot be pushed out by the auger. Therefore, after using the screen machine, it is necessary to manually use a long rod-shaped tool to reach in and clean it, otherwise it will form a blockage over time and affect the filtering effect. In addition, after flocculation and stirring, a large amount of solid sediment will be formed in the sewage. These sediments can easily block the conveying pipe when the sewage flows into the next filtering equipment. The pipe can only be cleaned by disassembling it, which seriously affects the use of the entire vehicle. Summary of the invention

[0043] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0044] Embodiment 1

[0045] Combination Figures 1 to 3As shown, the present invention provides an anti-clogging sewage rapid treatment vehicle, including a body 1, a screen machine 2, a hydraulic screen 3, a vacuum pump 4, a liquid delivery pump 5, a power take-off 6, a power take-off generator 7 and an outer shell box 8, wherein the body 1 is an existing commercial vehicle purchased, and its chassis is modified, and the outer shell box 8 is fixedly installed on the chassis of the body 1, and the screen machine 2, the hydraulic screen 3, the vacuum pump 4, the liquid delivery pump 5, and the power take-off generator 7 are all located in the outer shell box 8 and are all fixedly installed on the chassis of the body 1. The vacuum pump 4 in this embodiment is a PNK MR Roots vacuum pump, the liquid delivery pump 5 is a ZW non-clogging sewage drainage self-priming pump, the power take-off 6 is a Fast power take-off 6, the screen machine 2 and the hydraulic screen 3 are homemade equipment, and the vacuum pump 4, the liquid screen machine 2, the liquid delivery pump 5, and the hydraulic screen 3 are sequentially connected through pipelines (not shown in the pipeline diagram). The power take-off 6 is fixedly installed under the chassis of the vehicle body 1 and is transmission-connected to the main shaft of the engine of the vehicle body 1. The power take-off generator 7 is fixedly installed above the chassis of the vehicle body 1. The power take-off 6 and the power take-off generator 7 are transmission-connected. The power take-off generator 7 is electrically connected to the grid machine 2, the hydraulic screen 3, the vacuum pump 4, and the liquid delivery pump 5. The power take-off generator 7 obtains the power of the engine of the vehicle body 1 through the power take-off 6 and provides electrical energy for the equipment connected thereto. When the present invention is used, the grid machine 2 is first connected to a feed pipe and extended into the sewage pool to be treated. The grid machine 2 is pumped to negative pressure through the vacuum pump 4. At this time, the sewage is attracted to the grid machine 2 for preliminary filtration. The grid machine 2 will separate large solid impurities such as plastic bags, fruit cores, water bottles, etc. in the sewage. Then the liquid delivery pump 5 drives the sewage after preliminary treatment in the grid machine 2 into the hydraulic screen 3 for final treatment, filtering out solid waste that can be used as organic fertilizer and clean water that can be directly discharged. In the existing treatment vehicles, the sewage treated by the screen machine 2 generally needs to be flocculated, stirred and precipitated by equipment such as a mixing box to meet the treatment standards. According to existing experiments, when the hydraulic screen 3 is used for sewage treatment, the BOD removal efficiency is approximately equal to the initial precipitation. Therefore, the hydraulic screen 3 with a finer wire mesh can completely replace the traditional flocculation and stirring box. Compared with the latter, the hydraulic screen 3 has the advantages of simple structure, high treatment efficiency, small footprint, and convenient maintenance. It should be noted that the vacuum pump 4, power take-off 6 and power take-off generator 7 in the present invention can also be selected not to be installed on the vehicle body 1, but to use the existing mobile vacuum pump or power generation equipment on the ground. Installing it on the vehicle body 1 as in the present embodiment can make the anti-blockage sewage rapid treatment vehicle an independent system, which can work without external other power sources, so that the anti-blockage sewage rapid treatment vehicle can adapt to more occasions.

[0046] Furthermore, combined with Figures 4 to 8As shown, the screen machine 2 in this embodiment is an anti-clogging automatic slag discharge screen machine 2, which is fixedly installed on the chassis of the vehicle body 1, and includes a screen machine case 201, a screen machine screen 202, a screen drum 203, a screen machine auger 204, a screen drum cover 205, a screen machine discharge door 206, a first drive member 207 and a second drive member 208. The grille machine housing 201 is provided with a grille machine feed port 2011, a grille machine water outlet 2012 and a grille machine discharge port 2013, and the bottom of the grille machine housing 201 is also provided with legs for easy installation; the grille machine screen 202 is fixedly connected to the grille machine housing 201, and the grille machine screen 202 divides the interior of the grille machine housing 201 into a filter chamber and a sewage chamber, the filter chamber is located above the sewage chamber, and the filter chamber is mainly used for filtering, and the sewage chamber is used to store the liquid preliminarily filtered in the filter chamber, because there are still some impurities in the liquid after the preliminary filtration, so the filtered liquid is still sewage at this time and cannot be directly discharged; the grille machine feed port 2011 and the grille machine discharge port 2013 are both connected to the filter chamber, and the grille machine water outlet 2012 is connected to the sewage chamber; the screen cylinder 203 is located in the filter chamber , one end is connected to the first driving member 207, and the other end is connected to the screen machine feed port 2011; the screen machine auger 204 is located in the filter chamber, and includes a rotating shaft 2041, a spiral blade 2042, a supporting tube 2043 and four supporting top rods 2044, the spiral blade 2042 is sleeved on the rotating shaft 2041, one end of the rotating shaft 2041 is connected to the second driving member 208, and the other end faces the screen machine discharge port 2013, the four supporting top rods 2044 are fixedly connected to the outer wall of the screen machine case 201, the rotating shaft 2041 extends out of the screen machine discharge port 2013, the four supporting top rods 2044 are distributed circumferentially along the rotating shaft 2041, one end of each supporting top rod 2044 is abutted against the rotating shaft 2041, and the supporting top rods 2044 enable the rotating shaft 2041 to have two supporting points, so that the rotation is more stable. Sewage flows into the screen machine 2 from the screen machine feed port 2011 and enters the screen drum 203. The first driving member 207 drives the screen drum 203 to rotate and throw out the sewage. At this time, impurities in the sewage, such as plastic bags, worn-out clothes and food residues, will be retained in the screen drum 203, and sewage containing fine impurities such as mud and sand will be thrown out and fall on the screen 202 of the screen machine. The second driving member 208 drives the screen machine auger 204 to rotate and squeeze and dehydrate the solids in the thrown-out sewage. The filtered clean water will pass through the screen 202 of the screen machine and fall into the sewage cavity, realizing the initial separation of the sewage.

[0047] Furthermore, the first driving member 207 and the second driving member 208 in the present embodiment are both combination devices of a motor and a reducer, wherein the first driving member 207 is fixedly connected to the outer side of the grille case 201, and includes a first motor 2071 and a first reducer 2072, the axis of the first motor 2071 is parallel to the side plate of the grille case 201 to which it is connected, and the first motor 2071 is connected to the screen drum 203 through the first reducer 2072; the second driving member 208 is also fixedly connected to the outer side of the grille case 201, and includes a second motor 2081 and a second reducer 2082, the axis of the second motor 2081 is parallel to the side plate of the grille case 201 to which it is connected, and the second motor 2081 is connected to the screen drum 203 through the second reducer 2082. The output ends of the first motor 2071 and the second motor 2081 are parallel to the side plate of the grille machine housing 201, which can reduce the volume of the grille machine 2. The first reducer 2072 and the second reducer 2082 can increase the output torque while reducing the speed, and reduce the inertia of the load. The reduction in inertia is the square of the reduction ratio. In this embodiment, the output ends of the first reducer 2072 and the second reducer 2082 are both perpendicular to the side wall of the grille machine housing 201, that is, the screen drum 203 and the rotating shaft 2041 of the grille machine auger 204 are both parallel to the horizontal plane, which is not only convenient for opening and installation, but also easy to clean and filter evenly. It should be noted that the first drive member 207 and the second drive member 208 are not limited to the combination of the motor and the reducer in this embodiment. In actual implementation, other devices such as manual rockers can also be selected. However, when a manual drive device such as a manual rocker is selected, the grille machine 2 does not need to be electrically connected to the power generator 7. The manual drive device is suitable for an occasion where the initial filtration effect of sewage is not required to be high, and its filtration effect is not as good as that of the electric drive device.

[0048] Further, the screen drum cover 205 in this embodiment is hinged to the grille machine housing 201, and the screen drum cover 205 can operably close the grille machine feed port 2011. The screen drum cover 205 is provided with a pipe connection port 2051. The grille machine discharge door 206 in this embodiment is detachably connected to the grille machine housing 201 by bolts, and the grille machine discharge door 206 can operably close the grille machine discharge port 2013. The projection of the grille machine discharge door 206 on the side wall of the grille machine housing 201 connected thereto not only covers the grille machine discharge port 2013, but also covers the four supporting top rods 2044. The screen drum cover 205 makes the sealing effect of the grille machine feed port 2011 better. When the screen drum cover 205 is closed, the water inlet pipe can be connected to the pipe connection port 2051. When the screen drum cover 205 is opened, the screen drum 203 can be directly cleaned by using relevant tools. When the grille machine discharge door 206 is closed, the grille machine auger 204 can squeeze muddy water onto the grille machine discharge door 206 for extrusion dehydration. When the grille machine discharge door 206 is opened, the material can be discharged through the grille machine discharge port 2013. At this time, you can choose to manually clean it, or you can directly rotate the grille machine auger 204 to automatically push the squeezed waste out of the grille machine discharge port 2013. It should be noted that the connection method between the screen drum cover 205 and the grille machine housing 201, the screen machine discharge door 206 and the grille machine housing 201 is not limited to the connection method described in this embodiment. The screen drum cover 205 can be connected to the grille machine housing 201 by bolts, but this will make the screen drum cover 205 inconvenient to open and close. Similarly, the grille machine discharge door 206 can also be hinged to the grille machine housing 201. The purpose of selecting bolt connection in this embodiment is to improve the connection strength between the grille machine discharge door 206 and the grille machine housing 201, so as to achieve better extrusion dehydration effect.

[0049] Furthermore, the grille screen 202 in this embodiment includes two side nets 2021, a carrier net 2022 and a discharge net 2023, wherein the length direction of the carrier net 2022 is parallel to the axial direction of the rotating shaft 2041, and in this embodiment, the length direction of the carrier net 2022 is also parallel to the horizontal plane, the width direction of the carrier net 2022 is parallel to the horizontal plane, the cross section of the carrier net 2022 in the length direction is U-shaped, and the two sides of the carrier net 2022 in the width direction are respectively located at the grille machine twisted On both sides of the auger 204, the distance from the bottom of the carrying net 2022 to the rotating shaft 2041 remains unchanged along the length direction of the carrying net 2022; the two side nets 2021 are respectively located on both sides of the width direction of the carrying net 2022, one side of each side net 2021 is fixedly connected to the carrying net 2022, one side of each side net 2021 away from the auger 204 of the grille machine is fixedly connected to the grille machine box 201, and one side of each side net 2021 away from the auger 204 of the grille machine is higher than the side connected to the auger 204 of the grille machine. One side of the discharge net 2023 is fixedly connected to one end of the carrying net 2022 facing the discharge port 2013 of the grille machine, one side of the discharge net 2023 away from the carrying net 2022 extends out of the discharge port 2013 of the grille machine, and one side of the discharge net 2023 away from the carrying net 2022 is lower than the side connected to the carrying net 2022. In this way, the sewage falling onto the screen 202 of the grid machine can be filtered again by the screen 202 of the grid machine and fall into the sewage tank, while the sludge trapped above the screen 202 of the grid machine will flow into the carrier net 2022 along the two side nets 2021, and then be pushed to the discharge door 206 of the grid machine by the grid machine auger 204 for extrusion and dehydration. After dehydration, the discharge door 206 of the grid machine is opened, and at this time, because the discharge net 2023 is tilted downward, the waste residue formed by extrusion can be easily cleaned out from the discharge port 2013 of the grid machine.

[0050] Furthermore, in this embodiment, the axis of the screen drum 203 and the axis of the rotating shaft 2041 are located in the same vertical plane, the screen drum 203 is located above the screen machine auger 204, and the shapes of the two side nets 2021 are symmetrical along the plane where the axis of the screen drum 203 and the axis of the rotating shaft 2041 are located. This not only facilitates the processing of the two side nets 2021, but also makes the internal filtration more uniform, and there will be no sludge accumulation on one side to cause blockage.

[0051] Furthermore, the shape of the support pipe 2043 is consistent with the support net 2022, a water filter port is provided on the support pipe 2043, the support pipe 2043 is arranged between the spiral blade 2042 and the support net 2022, the outer arc surface of the support pipe 2043 abuts the support net 2022, and the inner arc surface of the support pipe 2043 abuts the spiral blade 2042. In the grille machine auger 204, the spiral blade 2042 is often rotating, and the connection between the rotating shaft 2041 and the grille machine housing 201 may be loose, which will cause the spiral blade 2042 to wear the support net 2022, so a support pipe 2043 with a filtering effect is added between the grille machine auger 204 and the support net 2022, and the support pipe 2043 is made of wear-resistant metal material, and the thickness of the support pipe 2043 is very thin, which can prevent sludge from clogging in the water filter port. The supporting tube 2043 can not only prevent the spiral blade 2042 from wearing the supporting net 2022, but also support the grille machine auger 204 to make its operation more stable.

[0052] Furthermore, in this embodiment, four supporting top wheels 2031 may be provided on the outer edge of the screen drum 203, and the four supporting top wheels 2031 are rotatably installed in the grille machine housing 201, and the four supporting top wheels 2031 are distributed along the circumference of the screen drum 203, and the four supporting top wheels 2031 are located in the same vertical plane, and the four supporting top wheels 2031 are all located on the side close to the grille machine feed port 2011. The rotation axes of the four supporting top wheels 2031 are all parallel to the axis of the screen drum 203, and the circumferential surface of each supporting top wheel 2031 abuts against the screen drum 203. Among the four supporting top wheels 2031, two supporting top wheels 2031 are fixedly connected to the top plate of the grille machine housing 201, and the other two supporting top wheels 2031 are fixedly installed on a cross bar, and the cross bar is located below the screen drum 203. When the screen drum 203 rotates, the solid impurities with large weight and volume contained therein will cause the screen drum 203 to vibrate violently, and over time, damage will occur at the connection with the grille housing 201. Therefore, a support top wheel 2031 is required to stabilize the rotation of the screen drum 203 and reduce the probability of damage. It should be noted that the number of the support top wheel 2031 and the above-mentioned support top rod 2044 can be adjusted according to existing needs.

[0053] Furthermore, the screen machine water outlet 2012 in this embodiment is located on a side panel of the screen machine case 201 away from the screen machine feed port 2011, and is located at the bottom of the side panel for easy drainage. At the same time, a flange connection plate is formed on the screen machine water outlet 2012 for easy connection of pipelines.

[0054] When the screen machine 2 in the anti-clogging sewage rapid treatment vehicle provided in the present embodiment treats sewage, since large areas of soft materials such as plastic bags, worn-out clothes and food residues have been removed when the sewage passes through the screen drum 203, the screen machine auger 204 acts on a solid-liquid mixture containing only fine particles such as mud and sand, and there will be no problem of impurities hanging on the screen machine auger 204. At the same time, since there is no protruding structure inside the screen drum 203, the work of cleaning the screen drum 203 is also extremely convenient. In this way, while there is no filtering dead corner, the probability of blockage of the screen machine 2 is greatly reduced, the number of cleaning times is reduced, and time costs are saved.

[0055] Furthermore, combined with Figures 9 to 14As shown, the hydraulic screen 3 in this embodiment includes a separation box 301, an adjustable slag pressing mechanism 302 and a hydraulic screen mesh 303. The separation box 301 is a box body made of stainless steel, surrounded by four side panels, with a bottom plate but no top plate, and the bottom of the separation box 301 has legs for installation; the separation box 301 is provided with a hydraulic screen water inlet 3011 and a hydraulic screen water outlet 3012, the hydraulic screen water inlet 3011 is a notch on the top formed by the four side panels, the hydraulic screen water outlet 3012 is located on a side panel and at the bottom of the hydraulic screen 3, and a flange connection plate for connecting a pipeline is formed on the hydraulic screen water outlet 3012. The adjustable slag pressing mechanism 302 is fixedly connected to a side wall of the separation box 301. The adjustable slag pressing mechanism 302 includes a screw conveyor 3021 and an adjusting part 3022, wherein the screw conveyor 3021 includes a pressing box 30211, a driving member 30212, a dehydration spiral blade 30213 and a dehydration shaft 30214. The pressing box 30211 is provided with a slag inlet and a slag discharge port; the dehydration shaft 30214 is partially located in the pressing box 30211, and one end of the dehydration shaft 30214 passes through the slag discharge port. The other end of the dehydration shaft 30214 is transmission-connected to the driving member 30212. The driving member 30212 in this embodiment is a Y series three-phase asynchronous motor, and the motor is located outside the pressing box 30211; the dehydration spiral blade 30213 is fixedly connected to the outer edge of the dehydration shaft 30214 located in the pressing box 30211; the adjustment part 3022 includes a fixing member 30221, a slag discharge door 30222, two abutting members 30223 and two adjusting rods 30224, wherein the fixing member 30221 is fixed The fixing member 30221 is a circular plate, and is fixedly connected to the side of the slag discharge port on the pressing box 30211. There is a gap between the fixing member 30221 and the pressing box 30211. One end of the rotating shaft 2041 of the hydraulic screen 3 is rotatably connected to the fixing member 30221. The slag discharge door 30222 is located between the fixing member 30221 and the pressing box 30211, and the slag discharge door 30222 is sleeved on the dehydration rotating shaft 30214. The abutting member 30223 is a straight rod, and one end of the abutting member 30223 is provided with a circular The abutment part 30223 abuts against the slag discharge door 30222, and the other end of the abutment part 30223 is connected to the fixing part 30221; one end of the adjusting rod 30224 is fixedly connected to the other end of the abutment part 30223, and the other end of the adjusting rod 30224 is away from the fixing part 30221, and the other end of the adjusting rod 30224 forms a hook. In this embodiment, one abutment part 30223 and one adjusting rod 30224 constitute a set of adjusting mechanisms, and the two adjusting mechanisms are rotatably connected to the fixing part 30221 in the same horizontal direction.In this embodiment, the hydraulic screen mesh 303 covers the hydraulic screen water inlet 3011. The material of the hydraulic screen mesh 303 is stainless steel. The mesh aperture can be selected according to needs, generally 16-100 mesh. The hydraulic screen mesh 303 has a first side and a second side. The first side is lower than the second side, and the first side extends to the slag inlet, that is, the hydraulic screen 3 forms a downward slope, and the adjustable slag pressing mechanism 302 is just below this slope.

[0056] The sewage after preliminary treatment by the screen machine 2 will be sent to the top of the hydraulic screen 3 by the liquid delivery pump 5 and fall on the hydraulic screen mesh 303. Since the hydraulic screen mesh 303 is in the shape of a slope, the sewage will remain along the hydraulic screen mesh 303 under the action of gravity, and the solids therein will be trapped above the mesh. The liquid will flow out from the gaps in the mesh and fall into the separation box 301, while the solids above will slide along the hydraulic screen mesh 303 to the adjustable slag pressing mechanism 302 for final extrusion and dehydration. In the adjustable slag pressing mechanism 302 in this embodiment, the screw conveyor 3021 can be used for extrusion dehydration, and the material that will be squeezed at the slag discharge port will apply an opening force to the slag discharge door 30222, and the slag discharge door 30222 in the adjustment part 3022 can be slidably sleeved on the rotating shaft 2041 of the hydraulic screen 3, and the abutment 30223 abutting therewith can apply a closing force in the opposite direction to the slag discharge door 30222. The smaller the difference between the opening force and the closing force, the smaller the gap between the slag discharge door 30222 and the slag discharge port, and the higher the dehydration efficiency. Therefore, by adding foreign matter between the abutment 30223 and the fixing member 30221 or hanging a heavy object on the adjusting rod 30224, the magnitude relationship between the opening force and the closing force can be changed to achieve the purpose of adjusting the dehydration efficiency. It should be noted that the shape and quantity of the fixing member 30221 and the abutment 30223 can be adjusted according to actual needs without referring to the description of this embodiment during specific implementation.

[0057] Furthermore, the squeezing box 30211 in this embodiment includes a slag delivery box 302111, a water collection box 302112 and a filter cartridge 302113, the dehydration shaft 30214 passes through the slag delivery box 302111 and the water collection box 302112 at the same time, the slag inlet is opened on the slag delivery box 302111, and the slag discharge port is opened on the water collection box 302112. The slag delivery box 302111 is a rectangular box without a top plate, and its length is the same as the width of the side plate of the hydraulic screen 3 fixedly connected thereto, and the notch on the top of the slag delivery box 302111 is the slag inlet. The water collecting box 302112 is connected to the slag delivering box 302111. A slag discharge port is provided on the side of the water collecting box 302112 facing away from the slag delivering box 302111, that is, the slag discharge door 30222 abuts the water collecting box 302112. The water collecting box 302112 is a box body that can be opened up and down, and a filter cartridge 302113 is fixedly connected to the inside thereof. The density of filter holes on the filter cartridge 302113 is less than or equal to the density of the screen mesh 202 of the grill machine. One end of the filter cartridge 302113 is connected to the connecting hole between the water collecting box 302112 and the slag delivering box 302111, and the other end of the filter cartridge 302113 is connected to the slag discharge port. Similarly, the dehydration spiral blade 30213 is also divided into a first spiral blade 302131 and a second spiral blade 302132. The first spiral blade 302131 is located in the slag delivery box 302111, and the second spiral blade 302132 is located in the water collecting box 302112. The pitch of the second spiral blade 302132 is smaller than that of the first spiral blade 302131, and the filter cartridge 302113 is sleeved outside the second spiral blade 302132. The slag box 302111 is mainly used to receive the solids remaining above the hydraulic screen 303. These solids still contain a part of water, so they need to be pushed into the water collecting box 302112 through the first spiral blade 302131. The second spiral blade 302132 in the water collecting box 302112 mainly plays the function of extrusion and dehydration. The squeezed water is collected by the water collecting box 302112, and the filter cartridge 302113 can not only play a filtering role, but also prevent the squeezed waste residue from falling directly into the water collecting box 302112, thereby playing the role of solid-liquid separation, which is convenient for subsequent processing when the water collecting box 302112 is opened. When squeezing, the material inside the filter cartridge 302113 pushes open the slag discharge door 30222 and overflows. The overflowing solid material is the solid waste separated after the final treatment, which can be used as organic fertilizer. At this time, the water in the water collection tank 302112 and the separation box 301 is the clean water obtained after treatment by the anti-clogging sewage rapid treatment vehicle, which can be discharged directly.

[0058] Furthermore, the separation box 301 in this embodiment includes a first baffle 3013, a second baffle 3014 and an overflow plate 3015, wherein the first baffle 3013 is vertically arranged, the first baffle 3013 is located at the top of a side wall of the separation box 301, one side of the first baffle 3013 is fixedly connected to the second side of the hydraulic screen 303, the second baffle 3014 is parallel to the first baffle 3013, the second baffle 3014 and the first baffle 3013 are fixedly connected to the same side wall of the separation box 301, and a buffer groove 9023 is formed between the first baffle 3013 and the second baffle 3014, and the length of the buffer groove 9023 is the same as the second side, that is, the length of the first baffle 3013 and the second baffle 3014 in this embodiment is the same as the second side; six feed ports 3016 are opened on the second baffle 3014, and the six feed ports 3016 are evenly distributed on the second baffle 3014 in the horizontal direction. The overflow plate 3015 is fixedly connected to the second baffle plate 3014. The overflow plate 3015 surrounds the buffer tank 9023 and the second side. There is a gap between the overflow plate 3015 and the hydraulic screen mesh 303. In this embodiment, the cross section of the overflow plate 3015 is L-shaped. One straight side of the overflow plate 3015 is connected to the second baffle plate 3014, and the other straight side of the overflow plate 3015 faces downward. The above-mentioned hydraulic screen water inlet 3011 is only an inlet for filtering function, and the feed port 3016 is the inlet for receiving sewage that is actually connected to the liquid delivery pump 5. After the sewage flows in from the feed port 3016, it will first be deposited in the buffer tank 9023. When a certain amount of sewage is accumulated in the buffer tank 9023, the sewage will cross the first baffle plate 3013 and flow to the hydraulic screen mesh 303 to start filtering. In this way, the sewage can be distributed on the hydraulic screen mesh 303 with a uniform water flow, and the filtering effect will not be affected by the accumulation of too much sewage locally. However, when the sewage enters at a high speed, the problem of uneven water flow distribution will still occur if only the buffer tank 9023 is relied on. At this time, an overflow plate 3015 needs to be installed. Since the gap between the overflow plate 3015 and the hydraulic screen mesh 303 remains unchanged, the water can be forced to flow out at a constant volume. At this time, the water flow rate at different positions on the hydraulic screen 303 may be different, but the volume is basically the same, so the negative impact caused by the uneven distribution of liquid on the hydraulic screen mesh 303 can be reduced. It should be noted that the number of feed ports 3016 can be adjusted to a suitable number according to actual needs.

[0059] Furthermore, the separation box 301 in this embodiment further includes two guard plates 3017, which are respectively located on both sides of the hydraulic screen mesh 303, with the first side parallel to the horizontal plane, the two guard plates 3017 are perpendicular to the first side, and the side of the guard plate 3017 facing away from the ground is parallel to the plane formed by the hydraulic screen mesh 303. The guard plates 3017 can prevent the sewage on the hydraulic screen mesh 303 from leaking from both sides of the hydraulic screen mesh 303, ensuring that it can flow into the adjustable slag pressing mechanism 302.

[0060] When the sewage treatment vehicle uses the hydraulic screen 3 to replace the flocculation and stirring equipment, not only does it save the time of waiting for flocculation and stirring, but also because the hydraulic screen 3 uses an adjustable slag pressing mechanism 302, the filtering effect becomes adjustable, which greatly improves the flexibility of the treatment vehicle. In addition, since there is no large volume of flocculated sediment, the problem of flocculated sediment blocking the conveying pipeline will not occur, which improves the anti-blocking performance of the treatment vehicle, reduces the frequency of disassembly, maintenance and dredging, improves work efficiency, and also reduces the time and labor cost required for vehicle maintenance.

[0061] Furthermore, combined with Figures 15 to 18As shown, the present embodiment further includes a flow stabilizing box 9, which includes a flow stabilizing box body 901 and a flow stabilizing baffle 902. The flow stabilizing box body 901 is a rectangular hollow box body, and a flow stabilizing box water inlet 903 and a flow stabilizing box water outlet 904 are provided on the flow stabilizing box body 901. The flow stabilizing box water inlet 903 is connected to the discharge port of the liquid delivery pump 5, and the flow stabilizing box water outlet 904 is connected to the hydraulic screen 3; the flow stabilizing baffle 902 is fixedly installed inside the flow stabilizing box body 901, and the projection of the flow stabilizing baffle 902 along the direction perpendicular to the flow stabilizing box water inlet 903 completely covers the flow stabilizing box water inlet 903, and the flow stabilizing box water inlet 903 and the flow stabilizing box water outlet 904 are respectively located on both sides of the flow stabilizing baffle 902. In this embodiment, the water inlet 903 of the stabilizing box is located on the bottom plate of the stabilizing box body 901, and the water outlet 904 of the stabilizing box is located on a side plate of the stabilizing box body 901 facing the hydraulic screen 3. The number of the water outlets 904 of the stabilizing box is six, which is consistent with the number of the feed ports 3016 in the hydraulic screen 3. The water outlets 904 of the stabilizing box are connected to the feed ports 3016 on the hydraulic screen 3 in a one-to-one correspondence. Because the water outlet rate of the liquid delivery pump 5 and the feed rate of the hydraulic screen 3 may not match, and when the liquid delivery equipment such as the self-priming pump is discharged, it is often not a gentle and stable water flow, but a water column with a high rate and great impact. In this case, if the water outlet of the self-priming pump is directly connected to the water inlet of the hydraulic screen 3, it will cause the liquid flowing out at the screen of the hydraulic screen 3 to also have a great impact and splash everywhere, and spray to the sewage treatment site, causing secondary pollution. After the flow stabilizer box 9 in this embodiment is installed between the liquid delivery pump 5 and the hydraulic screen 3, no matter how fast the water flows into the flow stabilizer box water inlet 903, it will not flow out directly from the flow stabilizer box water inlet 903, but directly contact the flow stabilizer baffle 902. The impact force of the water flow will act on the flow stabilizer baffle 902. After hitting the flow stabilizer baffle 902, the water flow will accumulate in the flow stabilizer box body 901. When the liquid level in the flow stabilizer box body 901 gradually rises to the height of the flow stabilizer box water outlet 904, the water in the flow stabilizer box body 901 will flow out smoothly from the flow stabilizer box water outlet 904, achieving the effect of reducing the impact of the water flow and preventing liquid splashing. It should be noted that when the number of feed ports 3016 of the hydraulic screen 3 changes, the number of flow stabilizer box water inlets 903 should also be changed accordingly, and is not limited to the six described in this embodiment.

[0062] Furthermore, the flow stabilizing baffle 902 in this embodiment is a composite plate, including a support layer 9021 and a buffer layer 9022. The support layer 9021 and the flow stabilizing box 901 are made of the same material, both made of stainless steel, and the buffer layer 9022 is made of waterproof rubber, and the buffer layer 9022 faces the water inlet 903 of the flow stabilizing box. In addition, a plurality of buffer grooves 9023 are provided on the side of the buffer layer 9022 away from the support layer 9021. The buffer layer 9022 can further reduce the impact of the water flow, not only can it play a role in stabilizing the flow, but also can reduce the impact on the flow stabilizing baffle 902, thereby reducing the stress at the connection between the flow stabilizing baffle 902 and the flow stabilizing box 901, reducing the probability of fracture at the connection between the flow stabilizing baffle 902 and the flow stabilizing box 901, and extending the service life of the equipment. The buffer groove 9023 can convert the vertical stress on the flow stabilizing baffle 902 into part of the lateral stress, further enhancing the above effect and making the flow stabilizing box 9 more durable.

[0063] Furthermore, the flow stabilizing baffle 902 in this embodiment is a rectangular straight plate, one side of the flow stabilizing baffle 902 is fixedly connected to a side plate of the flow stabilizing box 901 where the water outlet 904 of the flow stabilizing box is located, and there is a certain gap between the two horizontal sides of the flow stabilizing baffle 902 and the side plates of the flow stabilizing box 901 facing it, so as to ensure that the liquid in the flow stabilizing box 9 can rise evenly instead of just accumulating on one side of the flow stabilizing baffle 902. The extension direction of each buffer groove 9023 is perpendicular to the intersection line of the flow stabilizing baffle 902 and the side plate of the flow stabilizing box 901, and the angle between the flow stabilizing baffle 902 and the bottom plate of the box is between 15 and 75 degrees. Experiments have shown that such a setting can make the flow stabilizing baffle 902 have the best unloading effect and the longest service life.

[0064] After using the flow stabilizing box 9 in this embodiment to connect liquid conveying equipment such as a self-priming pump and the hydraulic screen 3, regardless of whether the specifications and models of the liquid conveying equipment and the hydraulic screen 3 match, they can be connected through the present invention without the problem of liquid splashing, thereby improving the interchangeability of existing equipment, that is, when the liquid conveying pump 5 or the hydraulic screen 3 on the assembly processing vehicle or the existing processing vehicle fails, the existing liquid conveying equipment or hydraulic screen 3 can be used for assembly without considering the problem of power matching, eliminating the step of additional procurement and saving the company's costs.

[0065] Furthermore, the anti-clogging sewage rapid treatment vehicle provided in this embodiment also includes a high-pressure dredging system 10, which includes a clean water tank 1001, a dredging machine 1002 and a dredging pipe 1003 connected in sequence, wherein the clean water tank 1001 is fixedly installed on the top plate of the outer shell box 8 and is located inside the outer shell box 8, the dredging pipes 1003 are fixedly installed above the chassis of the vehicle body 1, and the dredging machine 1002 is fixedly installed below the chassis of the vehicle body 1. The model of the dredging machine 1002 in this embodiment is UD2715BE, which is installed on the vehicle body 1 after modification. The dredging machine 1002 can pressurize the clean water in the clean water tank 1001 and spray it out from the dredging pipe 1003. At the same time, the pipe mouth of the dredging pipe 1003 has a special high-pressure nozzle. Due to the special structure of the nozzle of the dredging pipe 1003, the sprayed water has extremely high speed and energy, which can be used to crush or peel off the hard-to-clean oil, lumps and other materials on the inner wall of the sewage pool or the pipeline, so that they can be sucked into the screen machine 2 for treatment together with the sewage, thereby improving the processing capacity of the anti-blocking sewage rapid treatment vehicle. At the same time, the high-pressure dredging system 10 can also be used to clean up the work site after treating the sewage in the sewage pool, thereby improving the functionality of the anti-blocking sewage rapid treatment vehicle.

[0066] Furthermore, the anti-clogging sewage rapid treatment vehicle provided in this embodiment is also equipped with a corresponding electric control box 11, a control handle 12 and a hydraulic oil tank 13 for control. A signal receiver and a signal processor are arranged inside the electric control box 11, and are electrically connected to the control handle 12, the hydraulic oil tank 13, valves on the pipeline and other components. A display instrument control button is arranged on the electric control box 11. The electric control box 11 and the control handle 12 facilitate people to monitor the pressure and other data during the operation of the vehicle, control the start and stop of the equipment and the working timing of the related equipment.

[0067] Furthermore, the outer shell box 8 in this embodiment is provided with a plurality of closed doors. Since the outer shell box 8 is provided to surround the above-mentioned grille machine 2 and other equipment, the vehicle will not be disturbed by the outside world during operation, thereby improving its operation stability. However, this will affect the cleaning and maintenance of the vehicle after the vehicle is parked, so a plurality of closed doors are provided on the outer shell box 8. In addition, the outer shell box 8 also prevents the key equipment for treating sewage inside the vehicle from colliding with foreign objects when the vehicle is parked.

[0068] It should be noted that the models and specifications of the above-mentioned equipment such as the vacuum pump 4, various drive motors, self-priming pumps, high-pressure dredging machine 1002, etc. are not limited to the models and specifications provided in this embodiment. Without changing the types of components, they can be changed to other brands or specifications based on actual considerations of cost or demand. The vacuum pump 4 can use a water ring vacuum pump, the butterfly valve can be replaced by a ball valve, and the self-priming pump can also be replaced by a sludge pump.

[0069] The present invention provides a kind of anti-clogging sewage rapid treatment vehicle. During filtration, the sewage is first attracted to the grid and inside. At this time, since the sewage has removed a large area of ​​soft materials such as plastic bags, worn-out clothes and food residues when passing through the screen cylinder 203, the grid machine auger 204 squeezes a solid-liquid mixture containing only fine particles such as mud and sand, and there will be no problem of impurities hanging on the grid machine auger 204. At the same time, since there is no protrusion structure inside the screen cylinder 203, the work of cleaning the screen cylinder 203 is also very convenient, which greatly reduces the probability of clogging of the grid machine 2. In addition, since the hydraulic screen 3 has a high treatment efficiency, when the hydraulic screen 3 is used for sewage treatment, the BOD removal efficiency is approximately equal to the initial precipitation. Therefore, the present invention replaces the flocculation sedimentation equipment in the existing treatment vehicle with the hydraulic screen 3, which eliminates the time of waiting for the sewage to be stirred and precipitated, making the treatment process faster, and at the same time, there will be no flocculation sediment blocking the pipeline. In addition, by adding a flow stabilizer 9 and a high-pressure dredging device, the sewage treatment site is also made cleaner. In summary, the embodiments of the present invention have good practicability and can bring considerable economic benefits.

[0070] Embodiment 2

[0071] As the second embodiment of the present invention, different from the first embodiment, the flow stabilizing baffle 902 is an arc-shaped plate, and the protruding direction of the arc-shaped plate is away from the water inlet 903 of the flow stabilizing box. The flow stabilizing baffle 902 is formed by two straight sides and two arc-shaped sides, the two straight sides are parallel to each other, the shapes and protruding directions of the two arc-shaped sides are the same, and the direction of each buffer groove 9023 is the same as the arc-shaped side; one straight side is fixedly connected to the bottom plate of the flow stabilizing box body 901.

[0072] Compared with the first embodiment, when the flow stabilizing baffle 902 is hit by the water flow, since the flow stabilizing baffle 902 of this embodiment is arc-shaped, a part of the impact force received by the flow stabilizing baffle 902 will be decomposed into the impact force tangential to the arc edge, so that the flow stabilizing baffle 902 has a better force unloading effect and is less prone to damage. However, compared with the straight plate, the arc plate has a higher processing cost, and is not as convenient to transport and store as the straight plate.

[0073] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
