Technical Field

[0001] The present invention relates to the technical field of wastewater treatment for spice production, and specifically to a wastewater treatment device during the spice production process. Background Art

[0002] Spice wastewater is the wastewater generated during the spice processing. The wastewater contains various organic and inorganic substances. Therefore, when the wastewater is discharged, it needs to be treated to avoid polluting the environment. During the existing treatment of spice wastewater, the wastewater will be pretreated, that is, the large insoluble particles in the wastewater are first filtered out, and then the filtered wastewater is treated.

Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] Embodiment: A wastewater treatment device in the production process of spices, as Figures 1-9 shown, includes a treatment tank 1. The upper end of the treatment tank 1 is connected and communicated with an injection port 101 for injecting the wastewater generated in the production process of spices. It further includes: A collection box 2 is sleeved and communicated on the surface of the injection port 101. By providing the collection box 2, the function of waste collection can be achieved. It is worth noting that the bottom surface of the collection box 2 is inclined, which can play a role in guiding the flow. And at the lowest point of the bottom surface of the collection box 2, there is a discharge port communicated, which is convenient for discharging the collected waste. This discharge port is a prior art and is not shown in the figure; Among them, a plurality of groups of filter meshes 201 are equidistantly arranged inside the collection box 2. The filter meshes 201 are arranged directly below the injection port 101 and are used for filtering the wastewater in the production of spices, so that large particulate impurities insoluble in water in the wastewater are filtered out. It is worth noting that the number of the filter meshes 201 is set according to needs; A receiving groove 2011 is formed on the surface of the filter mesh 201, and the receiving groove 2011 is formed by connecting a group of strip-shaped grooves and a plurality of short grooves perpendicular to them. An annular groove 202 is formed around the inner wall of the collection box 2. By providing the receiving groove 2011 and the annular groove 202, the functions of guiding and limiting can be achieved; A mating tooth 203 is formed on the bottom surface of the annular groove 202, and driving teeth 204 are alternately formed on the top surface and the bottom surface of the annular groove 202. By providing the mating tooth 203 and the driving teeth 204, the function of driving can be achieved. It is worth noting that the driving teeth 204 and the mating tooth 203 are also arranged in a staggered manner. The mating tooth 203 is close to the inner wall of the collection box 2, and the driving teeth 204 are far from the inner wall of the collection box 2.

[0022] Combined with the attached Figure 1 - attached Figure 9, it further includes a conversion component 3 for driving the filter screen 201 to rotate, so that when too much impurities accumulate on the surface of one group of filter screens 201, it can be replaced to achieve continuous filtration treatment of wastewater; the conversion component 3 includes a rotating shaft 301 inserted into the collection box 2, and the upper end of the rotating shaft 301 is fixedly connected to a driving source. By setting the rotating shaft 301, it can play a positioning role and can move synchronously with the driving source to achieve the purpose of rotation; it should be noted that this driving source is a prior art and is not shown in the figure, and existing equipment such as a driving motor can be selected; Wherein, the lower end of the rotating shaft 301 is fixedly connected to a turntable 302, the surface of the turntable 302 is fixedly connected to a ring 303 through a strip-shaped rod, and the ring 303 is sleeved on the surface of multiple groups of filter screens 201, and the ring 303 is rotatably connected to the filter screen 201. By setting the turntable 302 and the ring 303, the rotation of the rotating shaft 301 can drive the turntable 302 and the ring 303 to rotate synchronously, so that the filter screen 201 installed in the ring 303 rotates to achieve the purpose of replacing the filter screen 201; it should be noted that multiple groups of filter screens 201 are all rotatably installed inside the ring 303, and combined with the shape of the collection box 2 with one side high and the other side low, the filter screen 201 located below the injection port 101 will not rotate when impacted by wastewater, ensuring the normal filtration of wastewater; multiple groups of gears 304 are rotatably connected to the surface of the rotating shaft 301 at equal intervals, one end of the gear 304 penetrates into the inside of the ring 303 and is fixedly connected to the surface of the filter screen 201, and the gear 304 is meshed with the mating tooth 203. By setting the gear 304, when the ring 303 rotates, the gear 304 can be driven to contact and mesh with the mating tooth 203 first, so that the replaced filter screen 201 rotates, and the filtering surface of the filter screen 201 is changed from an upward state to a downward state.

[0023] Combined with the attached Figure 1 - attached Figure 9 , it further includes a cleaning component 4 for flushing the filter screen 201, so that the replaced filter screen 201 can be flushed, which is convenient for the subsequent use of the filter screen 201; the cleaning component 4 includes a pulley group 401 sleeved on the surface of the rotating shaft 301. By setting the pulley group 401, it can play a role in kinetic energy transmission, so that when the rotating shaft 301 rotates, it can drive the pulley group 401 to rotate synchronously; it should be noted that the other end of the pulley group 401 is fixedly connected to the upper surface of the collection box 2; it should be noted that the other end of the pulley group 401 has a hollow structure inside; Among them, the upper end of the other end of the pulley group 401 is rotatably connected to a water injection port 402, and the upper end of the water injection port 402 is communicated with a water supply source for providing the water source required for cleaning the filter screen 201. The water supply source is a prior art and is not shown in the figure; the lower end of the other end of the pulley group 401 is rotatably connected to a conveying pipe 403. The water injection port 402 is communicated with the conveying pipe 403 through two groups of symmetrically arranged through holes 405 opened on the bottom surface. By providing the conveying pipe 403 and the through holes 405, it can be further communicated with the water injection port 402, so that the water source can enter the inside of the conveying pipe 403 through the water injection port 402; the lower end of the conveying pipe 403 is communicated with a cleaning pipe 404, and the cleaning pipe 404 is arranged directly above one of the filter screens 201. By providing the cleaning pipe 404, the water source can be sprayed out and act on the inverted filter screen 201 to clean the filter screen 201; it should be noted that multiple nozzles are communicated with the outer surface of the cleaning pipe 404, which are not shown in the figure due to the perspective reason.

[0024] Among them, a sealing ring 406 is arranged inside the water injection port 402, and the upper end of the sealing ring 406 is in a conical structure. By providing the sealing ring 406 and setting the upper end of the sealing ring 406 to be in a conical structure, when the sealing ring 406 moves upward, the water source inside the water injection port 402 will move to the outside of the sealing ring 406, avoiding the phenomenon that the pressure on the sealing ring 406 is too large and causing it to be unable to move; a vertical rod 407 is fixedly installed at the lower end of the sealing ring 406. The vertical rod 407 is inserted into the bottom of the water injection port 402, and the vertical rod 407 is slidably matched with the bottom surface of the water injection port 402 through symmetrically installed limit blocks on the surface. By providing the vertical rod 407, it can play a role in guiding and limiting the movement of the sealing ring 406; two groups of cross rods 408 are symmetrically installed on the surface of the vertical rod 407. By providing the cross rods 408, the lifting of the vertical rod 407 can be controlled through its lifting. Among them, a sleeve rod 409 is rotatably connected to the surface of the cross bar 408. By providing the sleeve rod 409, a buffering effect can be achieved, and at the same time, the friction with other components can be reduced, so as to better drive the lifting of the vertical rod 407. A top ring 410 is slidably fitted on the surface of the sleeve rod 409. The top ring 410 is arranged directly below the sleeve rod 409, and a plurality of groups of deep grooves are equidistantly formed on the surface of the sleeve rod 409. By providing the top ring 410 and forming deep grooves on the surface of the top ring 410, the sleeve rod 409 can be driven to lift when the top ring 410 rotates. Two groups of connecting rods 411 are symmetrically installed on the surface of the sleeve rod 409. The ends of the two groups of connecting rods 411 away from each other are fixedly connected to the inner wall of the other end of the pulley group 401. By providing the connecting rods 411, the top ring 410 can be connected to the inner wall of the other end of the pulley group 401, so that when the other end of the pulley group 401 rotates, the sleeve rod 409 can be driven to rotate and rise, so that the vertical rod 407 drives the sealing ring 406 to rise synchronously, so that water can enter the inside of the conveying pipe 403 from the through hole 405 and be sprayed out from the cleaning pipe 404 to clean the filter screen 201.

[0025] Combined with the attached Figure 1 - attached Figure 9 , it further includes an oscillation assembly 5 for vibrating the filter screen 201, so that when the filter screen 201 is cleaned, the filter screen 201 generates vibration to improve the cleaning efficiency of the filter screen 201. The oscillation assembly 5 includes a plurality of hollow shells 501. The plurality of hollow shells 501 are all in a triangular structure, and the hollow shells 501 are fixedly installed in the middle of the filter screen 201 and directly below the injection port 101. By providing the hollow shells 501 and setting them in a triangular structure, the waste water entering from the injection port 101 can be diverted, preventing large particle debris in the waste water from accumulating in one position, and at the same time reducing the impact force of the waste water on the filter screen 201. It should be noted that the hollow shells 501 are symmetrically and fixedly installed on both sides of each filter screen 201. Among them, multiple groups of hollow shells 501 are fixedly installed directly above the receiving groove 2011 and can seal the receiving groove 2011; multiple groups of swing rods 502 are equidistantly arranged inside the hollow shell 501, and the swing rods 502 are arranged at the connection of the strip-shaped groove and the short groove. A spherical head 503 is fixedly installed at the upper end of the swing rod 502. By arranging the swing rod 502 and the spherical head 503, it can swing reciprocally inside the short groove and collide with the inner wall of the hollow shell 501, thereby causing the filter screen 201 to vibrate and accelerating the cleaning efficiency of the filter screen 201; a rotating rod is fixedly connected to the lower end of the swing rod 502. One end of the rotating rod is rotatably connected to the inner wall of the receiving groove 2011, and the other end passes through the inside of the gear 304 and is rotatably connected to the gear 304. The rotating rod is inserted into the filter screen 201 and can drive the swing rod 502 to swing; a driven gear 504 is fixedly installed at one end of the rotating rod, and the driven gear 504 is meshed with the driving gear 204. By arranging the driven gear 504, when the filter screen 201 rotates synchronously with the ring 303, the gear 304 will first mesh with the mating tooth 203 to drive the filter screen 201 to flip, and then the driven gear 504 will contact the driving gear 204, causing the driven gear 504 to drive the rotating rod to swing reciprocally, so that the swing rod 502 drives the spherical head 503 to impact the inner wall of the hollow shell 501 and generate vibration, accelerating the cleaning efficiency.

[0026] Specifically, when treating wastewater, the wastewater is introduced from the upper end of the injection port 101 and acts on the filter screen 201 directly below the injection port 101. Through the diversion of the hollow shell 501 fixedly installed on the surface of the filter screen 201, the impact force of the wastewater on the filter screen 201 is reduced, and at the same time, large particulate impurities insoluble in water in the wastewater are filtered; when the filter screen 201 needs to be replaced, the driving source drives the rotating shaft 301 to rotate, so that the rotating shaft 301 drives the turntable 302 and the filter screen 201 installed inside the ring 303 to start rotating, replacing the filter screen 201 to ensure continuous filtration of the wastewater; during the rotation of the filter screen 201 following the ring 303, the replaced filter screen 201 will rotate under the cooperation of the gear 304 and the mating tooth 203, so that the filtering surface of the filter screen 201 changes from the upward state to the downward state. When the rotating shaft 301 rotates, it drives the pulley set 401 to rotate synchronously, causing the pulley set 401 to drive the top ring 410 to rotate through the connecting rod 411 and start to squeeze the sleeve rod 409 through the groove, causing the sleeve rod 409 to rotate and drive the vertical rod 407 fixedly connected to the cross bar 408 to move upward synchronously. The upward moving vertical rod 407 will drive the sealing ring 406 to rise and open the through hole 405, so that the water source inside the water injection port 402 can enter the inside of the delivery pipe 403 through the through hole 405 and be discharged through the cleaning pipe 404 to act on the replaced filter screen 201 to clean the filter screen 201. At the same time, the rotating ring 303 will also start to drive the driven gear 504 to contact and engage with the driving gear 204, causing the driven gear 504 to drive the swing rod 502 installed on the surface of the rotating rod to start reciprocating swing in the short slot, and drive the spherical head 503 to collide with the inner wall of the hollow shell 501, causing the filter screen 201 to vibrate and accelerating the cleaning efficiency.

[0027] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
