Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and particularly to a gelatin wastewater treatment device and process. Background Art

[0002] Gelatin is a macromolecular hydrophilic colloid and is the product of partial hydrolysis of collagen. During the production process of gelatin, a large amount of wastewater is generated, and the wastewater needs to be treated accordingly before it can be discharged.

[0003] Currently, during the treatment process of gelatin wastewater, especially during the pretreatment process of gelatin wastewater, filtration is mainly used for filtration, and the operation is simple. However, in the actual working process, the gelatin wastewater contains a large amount of colloids. These colloids accumulate on the outer side of the filter plate. A small amount of colloids can promote the precipitation filtration operation and attract large-particle substances in the gelatin wastewater. However, a large amount of colloids accumulating on the outer side of the filter plate will greatly affect the filtration effect of the filter plate. It is necessary to remove the colloids manually, which is time-consuming and laborious, and the cleaning effect is average. Moreover, these colloids will also block the filter holes and reduce the filtration effect. Therefore, a gelatin wastewater treatment device and process are provided. Summary of the Invention

[0004] The purpose of the present invention is to solve the disadvantages existing in the prior art, and a gelatin wastewater treatment device and process are proposed.

[0005] The present invention adopts the following technical solutions:

The circular rod abuts against the circular plate. A control plate is slidably sleeved up and down inside the sleeve. A cleaning plate is fixedly connected to the lower side of the control plate. The cleaning plate abuts against the filter plate.

[0008] Preferably, a stepped plate is fixedly connected inside the fixed frame. The stepped plate and the extrusion plate are arranged oppositely.

[0009] Preferably, a dredging component for dredging the filter plate is installed on the lower side of the stepped plate. The dredging component includes a first sliding groove formed in the lower side of the fixed frame. A first sliding plate is slidably connected up and down inside the first sliding groove. A third spring is fixedly connected between the first sliding plate and the side wall of the first sliding groove. A control rod is slidably sleeved up and down inside the stepped plate. A dredging plate is installed on the lower side of the control rod. Multiple groups of dredging rods are fixedly connected evenly to the lower side of the dredging plate.

[0011] Preferably, the side walls of the circular rod and the circular plate are both smooth.

Finally, during the rotation of the rotating plate, the movement of the extrusion plate will also drive the movement of the dredging plate and the dredging rod to form a dredging operation on the upper filter holes of the filter plate, ensuring the normal filtration effect of the filter holes, achieving multiple benefits with one action.

Detailed implementation mode

[0031] Refer to Figures 1-9 , a gelatin wastewater treatment device, including a cylinder body 1, a drain pipe is fixedly connected to the lower side of the cylinder body 1, a motor 2 is fixedly connected to the upper side of the cylinder body 1 through a plurality of groups of connecting rods, an output end of the motor 2 is fixedly connected to a rotating shaft 3, and a filter plate 4 is sleeved outside the rotating shaft 3; a cleaning assembly 5 for cleaning the deposits on the upper and lower sides of the filter plate 4 is installed in the cylinder body 1, as Figure 4 , Figure 5 , Figure 6 , Figure 7, the cleaning component 5 includes two groups of rotating plates 501. A rotating cylinder 502 is sleeved outside the rotating shaft 3. The upper rotating plate 501 is fixedly connected to the rotating cylinder 502, and the lower rotating plate 501 is threadedly sleeved with the rotating cylinder 502. The filter plate 4 is located between the two groups of rotating plates 501, and the filter plate 4 is rotatably sleeved outside the rotating cylinder 502. Cavities 505 are formed in both groups of rotating plates 501. A T-shaped plate 506 is slidably sleeved in the cavity 505. A first spring 507 is fixedly connected between the T-shaped plate 506 and the cavity 505. Fixing frames 503 are fixedly connected to one side of both groups of rotating plates 501 close to each other. A discharge pipe 515 is fixedly connected to the side wall of the fixing frame 503. A pump body is fixedly connected to the side of the discharge pipe 515 away from the fixing frame 503. The pump body is located outside the cylinder body 1. A button 516 for controlling the switch of the pump body is fixedly connected in the fixing frame 503. An extrusion plate 514 is slidably sleeved in the fixing frame 503. A transmission rod 509 is rotatably connected in the cavity 505. Two groups of gears 511 are fixedly sleeved outside the transmission rod 509. A first rack 508 is fixedly connected to the T-shaped plate 506 located in the cavity 505. The first rack 508 meshes with one of the gears 511. A second rack 510 is slidably connected in the cavity 505. The second rack 510 meshes with the other gear 511. A connecting plate 518 is fixedly connected to the lower side of the second rack 510. The connecting plate 518 penetrates through the side wall of the cavity 505, and the connecting plate 518 is fixedly connected to the extrusion plate 514. A stepped plate 504 is fixedly connected in the fixing frame 503. A deep groove is formed in the side wall of the extrusion plate 514. The deep groove is communicated with the moving groove 520. The cleaning plate 512 is arranged opposite to the deep groove;

[0032] First, both the cylinder body 1 and the filter plate 4 are arranged as regular polygons. During the rotation of the rotating shaft 3 driven by the motor 2, the filter plate 4 always abuts against the inside of the cylinder body 1. Secondly, the pump body is a pressure pump commonly used in real life, and the button 516 is the control switch of the pressure pump. When the button 516 is squeezed, the pressure pump is turned on, and suction can be formed to suck out the substances in the discharge pipe 515 and the space where the discharge pipe 515 is located. This is the prior art and will not be elaborated further. A nut is also threadedly sleeved on the outside of the rotating cylinder 502. After installing the filter plate 4 between the two rotating plates 501, the nut is screwed on the outside of the rotating cylinder 502 to make the connection between the rotating plate 501, the filter plate 4, and the rotating plate 501 tighter. Secondly, during the filtering operation, the motor 2 is started. The motor 2 drives the rotating plate 501 to rotate through the rotating shaft 3. Under the action of the first spring 507 (the first spring 507 is always in a stretched state), the T-shaped plate 506 always abuts against the inner wall of the cylinder body 1. Since the inner wall of the cylinder body 1 is a regular polygon, during the rotation of the rotating cylinder 502, the T-shaped plate 506 will move back and forth relative to the rotating plate 501. When the T-shaped plate 506 abuts against the corner of the regular polygon, the length of the T-shaped plate 506 outside the rotating plate 501 is the longest relative to the rotating plate 501. Then, during the continuous rotation of the T-shaped plate 506 following the rotating plate 501, the T-shaped plate 506 will gradually move to the right relative to the rotating plate 501 (based on Figure 5 the direction). Until the T-shaped plate 506 moves to the midpoint of the side line of the regular polygon, the length of the T-shaped plate 506 outside the rotating plate 501 is the shortest. As a result, during the rotation of the rotating plate 501, the T-shaped plate 506 moves back and forth relative to the rotating plate 501. The T-shaped plate 506 drives the first rack 508 to move. The first rack 508 drives the second rack 510 to move through the gear 511 and the transmission rod 509. The second rack 510 drives the pressing plate 514 to move back and forth through the connecting plate 518. The pressing plate 514 will drive the substances on the upper side of the filter plate 4 to move towards the direction close to the fixed frame 503. When the pressing plate 514 moves to the upper side of the stepped plate 504, the fixed frame 503, the stepped plate 504, and the pressing plate 514 form a sealed space. And during this process, most of the large-particle substances on the upper side of the filter plate 4 are located in this sealed space. During the continuous movement of the pressing plate 514, when the pressing plate 514 abuts against the button 516, the pump body is started, and the substances in this sealed space can be sucked out and then discharged to the outside of the cylinder body 1, without the need for manual cleaning, and the cleaning effect is good.

[0033] Such as Figure 8, shaking components for cleaning the colloids on the surface of the filter plate 4 are installed on the outer sides of both groups of rotating plates 501. The shaking components include a control frame 517 fixedly connected within a fixed frame 503. A plurality of groups of circular plates 519 are evenly and fixedly connected within the control frame 517. A moving groove 520 is formed in the side wall of the pressing plate 514. A sleeve 522 is slidably connected within the moving groove 520. A second spring 521 is fixedly connected between the sleeve 522 and the side wall of the moving groove 520. A circular rod 523 is fixedly connected to the upper side of the sleeve 522. The circular rod 523 abuts against the circular plate 519. A control plate 524 is slidably sleeved up and down within the sleeve 522. A cleaning plate 512 is fixedly connected to the lower side of the control plate 524. The cleaning plate 512 abuts against the filter plate 4. The side walls of the circular rod 523 and the circular plate 519 are both smoothly arranged;

[0034] First of all, during the movement of the pressing plate 514, the pressing plate 514 drives the cleaning plate 512 to move. The cleaning plate 512 is located above the filter plate 4 and abuts against the filter plate 4. When the pressing plate 514 moves, it drives the whole sleeve 522 to move. Under the action of the circular rod 523, the circular plate 519 and the second spring 521, when the sleeve 522 moves, since the circular rod 523 and the circular plate 519 always abut against each other, the circular rod 523 will drive the sleeve 522 to move back and forth relative to the pressing plate 514. Since the circular rod 523 is located above the filter plate 4, the sleeve 522 drives the cleaning plate 512 to move back and forth through the control plate 524. Most of the colloids on the upper side of the filter plate 4 will accumulate on the outer side of the cleaning plate 512. When the pressing plate 514 moves to the upper side of the stepped plate 504, the cleaning plate 512 will penetrate into the deep groove, and the colloids will be divided into two parts and accumulate on both sides of the pressing plate 514. A part of the closed space formed by the fixed frame 503, the stepped plate 504, and the pressing plate 514 will be sucked away. The remaining part of the colloids will attract large particle substances in the gelatin wastewater and continue with the corresponding precipitation and filtration operations.

[0035] Such as Figure 9, a dredging component 513 of the dredging filter plate 4 is installed on the lower side of the stepped plate 504. The dredging component 513 includes a first sliding groove 5133 opened on the lower side of the fixed frame 503. A first sliding plate 5135 is slidably connected up and down in the first sliding groove 5133. A third spring 5134 is fixedly connected between the first sliding plate 5135 and the first sliding groove 5133. A control rod 5131 is slidably sleeved up and down in the stepped plate 504. A dredging plate 5132 is installed on the lower side of the control rod 5131. A plurality of groups of dredging rods 5139 are uniformly and fixedly connected to the lower side of the dredging plate 5132. A second sliding groove 5136 is opened on one side of the dredging plate 5132 close to the fixed frame 503. A second sliding plate 5137 is slidably connected left and right in the second sliding groove 5136. A fourth spring 5138 is fixedly connected between the second sliding plate 5137 and the second sliding groove 5136. The second sliding plate 5137 is fixedly connected to the first sliding plate 5135. One side of the control rod 5131 located inside the fixed frame 503 is arc-shaped;

[0036] During the movement of the pressing plate 514, when the pressing plate 514 moves to the upper side of the stepped plate 504 and abuts against the control rod 5131, it will drive the control rod 5131 to move downward relative to the stepped plate 504. The control rod 5131 drives the dredging plate 5132 to move downward. The dredging plate 5132 drives the first sliding plate 5135 to move downward. The first sliding plate 5135 stretches the third spring 5134. The dredging plate 5132 drives the dredging rods 5139 to move downward. The dredging rods 5139 enter the filter plate 4 to perform a dredging operation on the filter plate 4. After the dredging rods 5139 enter the filter plate 4, the dredging rods 5139 and the dredging plate 5132 will not rotate with the rotating plate 501 and the fixed frame 503. The second sliding plate 5137 compresses the fourth spring 5138 until the connection between the pressing plate 514 and the control plate 524 is disconnected. At this time, under the action of the third spring 5134 and the fourth spring 5138, the dredging plate 5132 and the dredging rods 5139 return to their original positions relative to the fixed frame 503. As a result, during the rotation of the rotating plate 501, the filter plate 4 can still be dredged to ensure the dredging effect.

[0037] A gelatin wastewater treatment process includes the following steps:

[0038] S1. Pretreatment stage: Remove large particle suspended matters and part of grease in the wastewater by sedimentation and filtration. Subsequently, add a coagulant to form larger flocs from the colloidal substances and fine particles in the wastewater and precipitate them, and filter the flocs;

[0039] S2. Biological treatment stage: By means of an anaerobic digestion tank, utilize the metabolic action of microorganisms to decompose the organic matters in the wastewater and reduce the COD and ammonia nitrogen contents;

[0040] S3. Deep treatment stage: The A / O method is adopted to remove ammonia nitrogen pollutants in the gelatin wastewater.

[0041] In the present invention, when the filtering operation is carried out, the motor 2 is started. The motor 2 drives the rotating plate 501 to rotate through the rotating shaft 3. Under the action of the first spring 507 (the first spring 507 is always in a stretched state), the T-shaped plate 506 always abuts against the inner wall of the cylinder 1. Since the inner wall of the cylinder 1 is a regular polygon, during the rotation of the rotating cylinder 502, the T-shaped plate 506 will move back and forth relative to the rotating plate 501. When the T-shaped plate 506 abuts against the corner of the regular polygon, relative to the rotating plate 501, the length of the T-shaped plate 506 outside the rotating plate 501 is the longest. Then, during the continuous rotation of the T-shaped plate 506 following the rotating plate 501, the T-shaped plate 506 will gradually move to the right relative to the rotating plate 501 (taking Figure 5Based on the direction (until the T-shaped plate 506 moves to the midpoint of the side line of the regular polygon, the length of the T-shaped plate 506 outside the rotating plate 501 is the shortest. As a result, during the rotation of the rotating plate 501, the T-shaped plate 506 rotates back and forth relative to the rotating plate 501. The T-shaped plate 506 drives the first rack 508 to move. The first rack 508 drives the second rack 510 to move through the gear 511 and the transmission rod 509. The second rack 510 drives the pressing plate 514 to move back and forth through the connecting plate 518. The pressing plate 514 drives the substances on the upper side of the filter plate 4 to move towards the direction close to the fixed frame 503. When the pressing plate 514 moves to the upper side of the stepped plate 504, the fixed frame 503, the stepped plate 504, and the pressing plate 514 form a sealed space. And during this process, most of the large-particle substances on the upper side of the filter plate 4 are located in this sealed space. During the continuous movement of the pressing plate 514, when the pressing plate 514 abuts against the button 516, the pump body is started, and the substances in this sealed space can be sucked out and then discharged to the outside of the cylinder 1, without the need for manual cleaning, and the cleaning effect is good. During the movement of the pressing plate 514, the pressing plate 514 drives the cleaning plate 512 to move. The cleaning plate 512 is located on the upper side of the filter plate 4 and abuts against the filter plate 4. When the pressing plate 514 moves, it drives the whole sleeve 522 to move. Under the action of the round rod 523, the round plate 519 and the second spring 521, when the sleeve 522 moves, since the round rod 523 and the round plate 519 always abut against each other, the round rod 523 will drive the sleeve 522 to move back and forth relative to the pressing plate 514. Since the round rod 523 is located on the upper side of the filter plate 4, the sleeve 522 drives the cleaning plate 512 to move back and forth through the control plate 524. Most of the jelly-like substances on the upper side of the filter plate 4 will accumulate outside the cleaning plate 512. When the pressing plate 514 moves to the upper side of the stepped plate 504, the cleaning plate 512 will extend into the deep groove, and the jelly-like substances are divided into two parts and accumulate on both sides of the pressing plate 514. A part of the sealed space formed by the fixed frame 503, the stepped plate 504, and the pressing plate 514 will be sucked away, and the remaining part of the jelly-like substances will attract the large-particle substances in the gelatin wastewater and continue the corresponding precipitation and filtration operations. During the movement of the pressing plate 514, when the pressing plate 514 moves to the upper side of the stepped plate 504, when the pressing plate 514 abuts against the control rod 5131, it will drive the control rod 5131 to move downward relative to the stepped plate 504. The control rod 5131 drives the dredging plate 5132 to move downward. The dredging plate 5132 drives the first sliding plate 5135 to move downward. The first sliding plate 5135 stretches the third spring 5134. The dredging plate 5132 drives the dredging rod 5139 to move downward. The dredging rod 5139 enters the filter plate 4 to perform a dredging operation on the filter plate 4. After the dredging rod 5139 enters the filter plate 4, the dredging rod 5139 and the dredging plate 5132 will not rotate following the rotating plate 501 and the fixed frame 503. The second sliding plate 5137 compresses the fourth spring 5138,Until the connection between the extrusion plate 514 and the control plate 524 is disconnected, at this time, under the action of the third spring 5134 and the fourth spring 5138, the dredging plate 5132 and the dredging rod 5139 return to their original positions relative to the fixed frame 503, which further causes the dredging operation to be performed on the filter plate 4 during the rotation of the rotating plate 501, ensuring the dredging effect.
