Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly relates to a sewage treatment device for the recycling of soybean processing. Background Art

[0002] A large amount of wastewater is generated during the soybean processing. This wastewater contains organic substances such as proteins, fats, cellulose, and suspended solids. In order to achieve environmental protection and effective utilization of resources, it is usually necessary to recycle and treat this wastewater. Sewage treatment equipment plays a key role in this process. Especially in the primary stage, the filter cloth can intercept impurities in the sewage to ensure the smooth progress of subsequent treatment steps.

[0003] However, after the filter cloth of the existing soybean sewage treatment equipment is used for a long time, impurities are likely to accumulate. When the filter cloth is blocked due to the accumulation of impurities, the internal pressure of the system will rise rapidly, which may cause equipment damage or safety accidents. In order to prevent the filter cloth from being blocked due to the accumulation of impurities, it is mostly necessary to manually check and replace the filter cloth regularly. Frequent shutdowns for cleaning the filter cloth not only increase the labor cost, but also may cause production interruptions. Moreover, the replaced filter cloth also needs to be cleaned additionally. Thus, the overall working efficiency of soybean sewage treatment is significantly reduced. Summary of the Invention

[0004] In order to overcome the disadvantages mentioned in the above background art, the present invention provides a sewage treatment device for the recycling of soybean processing.

[0005] A sewage treatment device for the recycling of soybean processing includes a machine case. A storage cavity and a collection cavity are arranged inside the machine case. The collection cavity is located outside the storage cavity. A feeding frame is connected to the top of the machine case. Inside the collection cavity of the machine case, there are roller shafts symmetrically distributed along the machine case and rotatably connected. Two belts are connected between all the roller shafts. A filter cloth is fixedly connected between the two belts. The roller shafts guide the filter cloth. A motor is fixedly connected outside the machine case. The output shaft of the motor is fixedly connected to any one of the roller shafts. Inside the storage cavity, there is a bearing frame rotatably connected. One side of the bearing frame supports the bottom of the filter cloth near the feeding frame. Inside the storage cavity, there is a rotating shaft rotatably connected. There are first springs symmetrically distributed along the rotating shaft and fixedly connected between the rotating shaft and the bearing frame. A first adjusting plate is slidably connected to the feeding frame. The feeding frame is provided with a spare passage. The first adjusting plate is used to control the opening size of the spare passage. The bearing frame is provided with a triggering component for triggering the self-starting of the motor when the impurities intercepted by the filter cloth accumulate to the upper limit.

[0006] Furthermore, the triggering component includes rotating rods symmetrically distributed along the bearing frame. The rotating rods are fixedly connected to the bearing frame. The rotating rods are rotatably connected with connecting rods. The connecting rods are rotatably connected with a guiding plate for pushing and pulling the first adjusting plate to move up and down. The guiding plate is slidably connected to the feeding frame.

[0007] Further, a chute is formed on one side of the guide plate close to the first adjusting plate, and the guide plate is slidably connected to the first adjusting plate through the chute.

[0008] Further, the triggering assembly further includes a contact switch, which is fixedly connected to the blanking frame. When the guide plate on the side close to the contact switch slides along the blanking frame, it contacts the contact switch, and the contact switch is electrically connected to the motor through a control module.

[0009] Further, a worm gear is further included. The worm gear is fixedly connected to the rotating shaft, a worm is rotatably connected to the machine case, the worm meshes with the worm gear, a first gear is fixedly connected to the worm, a slide rail is fixedly connected to the blanking frame, a toothed rack is slidably connected to the slide rail, and the toothed surface of the toothed rack meshes with the first gear. A second spring is fixedly connected between the slide rail and the toothed rack.

[0010] Further, a rotating plate is further included. The rotating plate is rotatably connected inside the blanking frame, a second adjusting plate is slidably connected to the rotating plate, a sliding frame is rotatably connected to the second adjusting plate, and the sliding frame is fixedly connected to the toothed rack.

[0011] Further, a cleaning brush for timely cleaning the residual impurities on the filter cloth is further included. The cleaning brush is rotatably connected to the lower part of the collection cavity of the machine case.

[0012] Further, a second gear is further included. The second gear is fixedly connected to the end of the roller shaft on the side close to the cleaning brush, and a third gear is fixedly connected to the cleaning brush. The third gear meshes with the second gear.

[0013] The beneficial effects are as follows: When the impurities intercepted by the filter cloth accumulate to the upper limit, the weight of the accumulated impurities causes the filter cloth to sink locally, thereby triggering the self-starting of the motor, and the filter cloth is transmitted counterclockwise. In this way, on the one hand, the clean part on the right side of the filter cloth is automatically transferred to the position of the filter cloth close to the water outlet of the blanking frame to realize the automatic replacement of the filter cloth. On the other hand, the impurities originally intercepted by the filter cloth are automatically transferred and poured to the left to realize the automatic collection of the impurities.

[0014] When the present invention triggers the self-starting of the motor, it also makes the first adjusting plate move upward adaptively. By dynamically adjusting the first adjusting plate, the standby channel can be opened in time for water drainage to achieve the effect of pressure relief protection. In this way, the replacement of the filter cloth, the collection of impurities, and the timely water drainage work together, greatly reducing the probability that the filter cloth is blocked due to the accumulation of impurities in the soybean sewage. In this way, it is possible to normally realize the cyclic treatment of soybean sewage without frequent shutdown for cleaning the filter cloth.

[0015] The present invention uses the rotating plate to deflect adaptively according to the magnitude of the impact force of the sewage, dynamically adjusting the difficulty of the bearing frame swinging downward to resist the influence of the impact force of the sewage on the bearing frame, preventing the premature action of a large sewage impact force on the bearing frame and causing mis-touch phenomenon. In this way, the premature self-starting of the motor is avoided.

[0016] In the present invention, the rotation of the roller shaft at the lower left drives the rotation of the second gear, thereby driving the rotation of the third gear, and further driving the rotation of the cleaning brush, so that the impurities remaining on the filter cloth are automatically and timely cleaned.

Detailed implementation manners

[0029] The present invention will be specifically introduced below in conjunction with the attached drawings and specific embodiments.

[0030] Embodiment 1: A sewage treatment device for the recycling of soybean processing, as Figures 1 - 5 shown, includes a chassis 101. A storage cavity 102 and a collection cavity are arranged in the chassis 101. The collection cavity is located outside the storage cavity 102. The left side of the top of the chassis 101 is communicated with a blanking rack 103. The soybean sewage discharged from the upstream equipment enters the blanking rack 103. Roller shafts 104 that are symmetrically distributed along the left and right of the chassis 101 are rotatably connected to both the upper and lower sides in the collection cavity of the chassis 101. Both the front and rear sides between the four roller shafts 104 are connected with a belt 105. A filter cloth 106 is fixedly connected between the two belts 105. The roller shafts 104 guide the filter cloth 106. The left upper part of the front side outside the chassis 101 is fixedly connected with a motor 107. The output shaft of the motor 107 is fixedly connected with the upper left roller shaft 104. A bearing rack 108 is rotatably connected to the upper left part in the storage cavity 102. The bearing rack 108 swings downward under the action of the gravity of the accumulated impurities. The right side of the bearing rack 108 supports on the bottom of the filter cloth 106 near the bottom side of the blanking rack 103. A rotating shaft 109 is rotatably connected in the storage cavity 102. First springs 110 that are symmetrically distributed along the front and rear of the rotating shaft 109 are fixedly connected between the rotating shaft 109 and the bearing rack 108. The right side of the blanking rack 103 is slidably connected with a first adjusting plate 111 in the vertical direction. A standby channel 112 is opened at the lower right part of the blanking rack 103. When impurities accumulate on the filter cloth 106 and cause the bottom of the blanking rack 103 to be blocked, the first adjusting plate 111 slides downward to open the standby channel 112. The first adjusting plate 111 can adjust the opening size of the standby channel 112.

[0031] As Figure 2 and Figure 6As shown in the figure, it further includes rotating rods 201 symmetrically distributed before and after along the carrier 108. The rotating rods 201 are fixedly connected to the ends of the carrier 108. The upper ends of the rotating rods 201 are rotatably connected to connecting rods 202. The right ends of the connecting rods 202 are rotatably connected to guide plates 203. The guide plates 203 are slidably connected to the blanking frame 103. On the side of the guide plate 203 close to the first adjusting plate 111, an inclined slot is opened which slopes from the upper left to the lower right. The guide plate 203 is slidably connected to the first adjusting plate 111 through the inclined slot, so that the left and right sliding of the guide plate 203 can push and pull the first adjusting plate 111 to move up and down. A contact switch 204 is fixedly connected to the lower part of the front side of the blanking frame 103. When the front guide plate 203 slides to the right along the blanking frame 103, the front guide plate 203 contacts the contact switch 204. The contact switch 204 is electrically connected to the motor 107 through a control module.

[0032] The soybean sewage discharged from the upstream equipment enters the storage cavity 102 through the blanking frame 103. During the process of entering the storage cavity 102, the sewage will pass through the filter cloth 106. The filter cloth 106 can physically intercept impurities such as flocculants (such as the oil aggregates treated by polysilicic acid iron) and solid particles in the soybean sewage. As the impurities intercepted by the filter cloth 106 increase, the position of the filter cloth 106 close to the water outlet of the blanking frame 103 begins to gradually sink, causing the carrier 108 to swing downward. The first spring 110 is stretched. The carrier 108 drives the rotating rod 201 to rotate. The rotating rod 201 pushes the guide plate 203 to slide to the right through the connecting rod 202 until the guide plate 203 contacts the contact switch 204. At this time, it means that the impurities intercepted by the filter cloth 106 have accumulated to the upper limit, which may cause the filter cloth 106 to be blocked. Therefore, the contact switch 204 emits an electrical signal. The control module receives the electrical signal and controls the output shaft of the motor 107 to rotate, thereby driving the roller 104 at the upper left to rotate, and then driving the belt 105 to transmit counterclockwise. The transmission of the belt 105 causes the other rollers 104 to also rotate. In this way, the belt 105 drives the filter cloth 106 to transmit counterclockwise, so that the clean part on the right side of the filter cloth 106 moves to the left to the position of the filter cloth 106 close to the water outlet of the blanking frame 103, and the original position of the filter cloth 106 close to the water outlet of the blanking frame 103 moves to the left. The impurities intercepted on the filter cloth 106 also move to the left. Finally, the transferred impurities fall downward into the collection cavity of the chassis 101 under the action of gravity. In addition, when the guide plate 203 moves to the right, the guide plate 203 squeezes the first adjusting plate 111 to move upward adaptively through the inclined slot, so that the first adjusting plate 111 adaptively opens the standby channel 112 to prevent the position of the filter cloth 106 close to the water outlet of the blanking frame 103 from being blocked due to excessive accumulation of impurities, resulting in an increase in the water pressure in the blanking frame 103 and the upstream equipment of the blanking frame 103.

[0033] In summary, when the impurities intercepted by the filter cloth 106 accumulate to the upper limit, the weight of the accumulated impurities causes the filter cloth 106 to sink locally, thereby triggering the self-start of the motor 107, causing the filter cloth 106 to be transported counterclockwise. In this way, on the one hand, the clean part on the right side of the filter cloth 106 is automatically transferred to the position of the filter cloth 106 close to the water outlet of the blanking rack 103, realizing the automatic replacement of the filter cloth 106. On the other hand, the filter cloth 106 automatically transfers the previously intercepted impurities to the left and dumps them, realizing the automatic collection of impurities.

[0034] When the present invention triggers the self-start of the motor 107, it also causes the first adjusting plate 111 to move upward adaptively. By dynamically adjusting the first adjusting plate 111, the standby channel 112 can be opened in time for draining water, achieving the effect of pressure relief protection. In this way, the replacement of the filter cloth 106, the collection of impurities, and the timely draining of water work together in parallel, greatly reducing the probability of the filter cloth 106 being blocked due to the accumulation of impurities in the soybean sewage. In this way, it is possible to normally realize the cyclic treatment of soybean sewage without frequent shutdown for cleaning the filter cloth 106.

[0035] As Figure 7 and Figure 8 shown, it further includes a worm gear 301. The worm gear 301 is fixedly connected to the front end of the rotating shaft 109. The upper part of the front side of the chassis 101 is rotatably connected with a worm 302. The lower part of the worm 302 meshes with the worm gear 301. The upper part of the worm 302 is fixedly connected with a first gear 303. The left side of the blanking rack 103 is fixedly connected with a slide rail 305. The slide rail 305 is slidably connected with a toothed rack 304 in the left-right direction. The front side of the toothed rack 304 is provided with a tooth surface, and the tooth surface of the toothed rack 304 meshes with the first gear 303. A second spring 306 is fixedly connected between the slide rail 305 and the toothed rack 304.

[0036] As Figure 9 shown, it further includes a rotating plate 401. The rotating plate 401 is rotatably connected to the left side inside the blanking rack 103. A second adjusting plate 402 is slidably connected to the rotating plate 401. The bottom of the second adjusting plate 402 is rotatably connected with a sliding frame 403. The sliding frame 403 is fixedly connected to the toothed rack 304.

[0037] In addition to the gravity of the impurities accumulated on the filter cloth 106, the bearing frame 108 may also be affected by the impact force of the sewage. When the impact force of the sewage is relatively large, it may cause an accidental touch due to the impact force of the sewage acting on the bearing frame 108 in advance, resulting in the premature self-start of the motor 107. To avoid this situation, it is necessary to dynamically adjust the difficulty of the bearing frame 108 swinging downward according to the magnitude of the impact force of the sewage. The specific operation is as follows:

[0038] When sewage enters the blanking rack 103, the sewage impacts the rotating plate 401. The rotating plate 401 adaptively deflects to the left according to the magnitude of the impact force of the sewage. The rotating plate 401 pushes the sliding rack 403 to move to the left through the second adjusting plate 402. The sliding rack 403 drives the toothed rack 304 to slide to the left along the slide rail 305. The second spring 306 is adaptively compressed. The toothed rack 304 drives the first gear 303 to rotate through the tooth surface, thereby driving the worm 302 to rotate, and further driving the worm gear 301 to rotate, and then driving the rotating shaft 109 to rotate, so that the rotating shaft 109 adaptively tightens the first spring 110, thereby adaptively increasing the difficulty of the bearing frame 108 swinging downward. In this way, the greater the sewage impact force, the greater the angle of the rotating plate 401 deflecting to the left, and the greater the difficulty of the bearing frame 108 swinging downward, so as to resist the influence of the sewage impact force on the bearing frame 108.

[0039] As Figure 10 and Figure 11 shown, it further includes a second gear 501. The second gear 501 is fixedly connected to the front end of the roller shaft 104 at the lower left side. A cleaning brush 502 is rotatably connected to the lower left side in the collection cavity of the machine case 101. The cleaning brush 502 is used to timely clean the impurities remaining on the filter cloth 106. A third gear 503 is fixedly connected to the front end of the cleaning brush 502. The third gear 503 meshes with the second gear 501.

[0040] The rotation of the roller shaft 104 at the lower left side drives the second gear 501 to rotate, thereby driving the third gear 503 to rotate, and further driving the cleaning brush 502 to rotate, so that the impurities remaining on the filter cloth 106 are automatically and timely cleaned.

[0041] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
