Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to wastewater treatment equipment in a corn processing process. Background Art

[0002] Corn is one of the most important food crops in the world, and its processing industry plays an irreplaceable role in many fields such as food, feed, chemical industry and energy. Corn processing covers a series of processes from primary threshing and drying to complex starch extraction, saccharification, fermentation and ethanol production. A large amount of wastewater will be generated during corn processing. The wastewater contains a large amount of organic matter, suspended solids, nutrients such as nitrogen and phosphorus, and possible chemical additives. If it is directly discharged without proper treatment, it will cause serious pollution to the environment.

[0003] Filter pressing is a commonly used solid-liquid separation technology, which is widely used in various industrial wastewater treatments. By applying pressure, the liquid passes through the filter medium, while the solid particles are trapped in the filter chamber, thereby achieving solid-liquid separation. For corn processing wastewater, filter pressing can effectively remove suspended solids and some soluble organic matter in the wastewater, reducing the burden of subsequent biological treatment or physical and chemical treatment. When using a traditional filter press, it is necessary to provide a large extrusion force for the wastewater so that the impurities in the wastewater can squeeze each other to achieve the dehydration effect. Therefore, it is necessary to provide a large amount of energy for the filter press, and its energy loss is large. In addition, when cleaning the solid impurities after filter pressing, it is necessary to shut down, and a continuous treatment process cannot be achieved. Summary of the invention

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0036] like Figures 1 to 9 As shown, a wastewater treatment device in a corn processing process of the present invention comprises a support structure and a rotating disk 2;

[0037] The support structure is used to support the turntable 2, and the support structure includes a fixed outer ring 1, the axis of the fixed outer ring 1 is vertical, a first support ring 3 is rotatably provided on the upper end surface of the fixed outer ring 1, and a second support ring 4 is rotatably provided on the lower end surface of the fixed outer ring 1, and the first support ring 3 and the second support ring 4 are connected by two support seats 5;

[0038] The turntable 2 is located between two support seats 5, and the axis of the turntable 2 is horizontal. The turntable 2 rotates on the support seat 5 with the axis of the turntable 2 as the axis. The turntable 2 is hollow inside, and a plurality of mesh plates 6 are arranged on the inner wall of the turntable 2. The plurality of mesh plates 6 are distributed in a ring shape around the axis of the turntable 2.

[0039] Among them, a water channel structure is arranged on one end surface of the turntable 2, and a material discharge structure is arranged on the other end surface of the turntable 2.

[0040] In detail, the fixed outer ring 1 supports the turntable 2 through the first support ring 3, the second support ring 4 and the support seat 5. The axis of the turntable 2 is perpendicular to and intersects with the axis of the fixed outer ring 1. When the turntable 2 rotates rapidly around the axis of the fixed outer ring 1, the wastewater in the turntable 2 can undergo centrifugal motion, and the wastewater gathers on the horizontal plane to the left and right positions farthest from the axis of the turntable 2 inside the turntable 2. At this time, impurities in the wastewater also gather to this position. The centrifugal speed at this position is the fastest, and the centrifugal force obtained by the impurities is the largest. In this way, the centrifugal force is used to make the impurities gather at this position of the turntable 2 and squeeze each other, and the water between the impurities is squeezed out. The turntable 2 is rotated slowly with its own axis as the axis, and the turntable 2 drives multiple mesh plates 6 therein to rotate synchronously. When the mesh plate 6 moves to the impurity position in the centrifugal filtration state and moves upward, the mesh plate 6 will carry the impurities away from the liquid surface, so that the impurities after filtration are separated from the water, and the separated impurities can be discharged through the discharge structure. The water channel structure can continuously introduce wastewater into the turntable 2, and the wastewater in the middle position of the turntable 2 after centrifugal treatment can be discharged through the water channel structure, and the discharge structure allows continuous discharge, thereby realizing a continuous and low-energy automatic treatment working mode of wastewater.

[0041] Since the wastewater is also in a centrifugal state and the shape of the turntable 2 is circular, the wastewater only gathers at the position of the inner wall of the turntable 2 in the horizontal direction that is farthest from the axis of the turntable 2, and will not fill the turntable 2 or occupy too much space. When the turntable 2 performs a circular motion with the axis of the fixed outer ring 1 as the axis, the turntable 2 will drive the first support ring 3, the second support ring 4 and the support seat 5 to move synchronously. When the turntable 2 rotates, the turntable 2 will slide on the support seat 5. The setting of the mesh plate 6 is mainly to push away the condensed impurities to achieve the purpose of continuous discharge of impurities.

[0042] Through the action of centrifugal force, solid impurities in the wastewater are quickly gathered and squeezed, thereby achieving efficient solid-liquid separation. Compared with traditional filter presses, this method can complete the separation process in a shorter time and improve the processing efficiency. Since centrifugal force is used to achieve dehydration, the dependence on large extrusion force is reduced, and energy consumption is reduced. The equipment design allows continuous introduction and discharge of wastewater, and can continuously discharge solid impurities after filtration, which allows the entire treatment process to be carried out uninterruptedly, greatly improving production efficiency and simplifying the operating procedures.

[0043] Furthermore, the cross-sectional shape of the inner circumferential wall of the turntable 2 is V-shaped, and the opening of the V-shape faces the axial direction of the turntable 2 .

[0044] In detail, by setting the inner wall shape of the turntable 2 to be V-shaped, the effect of self-agglomeration of impurities due to centrifugal action can be improved, thereby improving the dehydration effect.

[0045] Furthermore, the water channel structure includes a first side plate 7 rotatably mounted on one end surface of the turntable 2, the first side plate 7 is coaxial with the turntable 2, and a first water inlet pipe 8 and an overflow pipe 33 are connected to the first side plate 7;

[0046] The end of the first water inlet pipe 8 away from the rotating disk 2 is fixed on the first support ring 3, and the first support ring 3 is provided with a second water inlet pipe 9 connected with the first water inlet pipe 8, the input end of the second water inlet pipe 9 is vertical and coaxial with the fixed outer ring 1, and a third water inlet pipe 10 is rotatably sleeved on the second water inlet pipe 9, and the third water inlet pipe 10 is fixed to the fixed outer ring 1 through a first support plate 11;

[0047] A filter screen 34 is provided between the overflow pipe 33 and the rotating disk 2 .

[0048] In detail, wastewater can be continuously introduced into the turntable 2 through the third water inlet pipe 10, the second water inlet pipe 9 and the first water inlet pipe 8. The wastewater in the middle position inside the turntable 2 can overflow through the overflow pipe 33. The filter screen 34 can intercept impurities in the wastewater. Since the first support ring 3 needs to perform synchronous circular motion with the turntable 2, the second water inlet pipe 9 rotates, and the third water inlet pipe 10 is supported and limited by the first support plate 11 and is stationary, the wastewater can be directly introduced into the rotating second water inlet pipe 9 through the stationary third water inlet pipe 10, thereby realizing the smooth supply of wastewater.

[0049] Furthermore, the discharge structure includes a second side plate 12 rotatably mounted on the other end face of the turntable 2, a discharge elbow 13 is obliquely inserted into the second side plate 12, the end of the discharge elbow 13 on the inner side of the turntable 2 faces upward and is connected to a receiving hopper 14, the end of the discharge elbow 13 on the outer side of the turntable 2 faces downward and is coaxial with the fixed outer ring 1, and the discharge elbow 13 is connected to the second support ring 4 via a second support plate 15.

[0050] In detail, when the mesh plate 6 in the turntable 2 carries impurities and moves to the highest point inside the turntable 2, the centrifugal force of the impurities is reduced to the minimum value. At this time, the mesh plate 6 is vertical, and the impurities can naturally fall from the mesh plate 6 into the receiving hopper 14. The impurities in the receiving hopper 14 can be naturally discharged through the discharge elbow 13, thereby realizing the automatic removal of impurities. The second support plate 15 will connect and support the discharge elbow 13 and the second support ring 4.

[0051] Furthermore, a universal joint is arranged in the discharge elbow 13, and support shafts 17 are arranged at both ends of the universal joint. A plurality of blades 18 are arranged on the outer wall of each support shaft 17, and a third support ring 19 is arranged at the outer end of the plurality of blades 18. The third support ring 19 is rotatably mounted on the inner wall of the discharge elbow 13, and a plurality of conical cutters 20 are arranged at equal intervals on the side wall of the blade 18.

[0052] In detail, since the shape of the discharge elbow 13 is curved, it is necessary to make the two support shafts 17 parallel to the two straight segments on the discharge elbow 13, and then use a universal joint to connect the two support shafts 17. The isolation cover 16 is mainly used to protect the universal joint, and the blade 18 and the third support ring 19 are used to support the support shaft 17. When one support shaft 17 rotates, it will drive the other support shaft 17 to rotate through the universal joint, and the support shaft 17 drives the blade 18 and the third support ring 19 to rotate. The blade 18 will crush the condensed impurities in the discharge elbow 13 to prevent the impurities from clogging the discharge elbow 13. At the same time, the conical knife 20 can improve the crushing effect.

[0053] Furthermore, a support shaft 17 in the discharge elbow 13 is vertical, an impact wheel 21 is eccentrically provided on the top of the support shaft 17, and the mesh plate 6 is made of soft material.

[0054] In detail, the mesh plate 6 can be made of materials such as rubber and woven materials. When the mesh plate 6 moves to the upper side of the turntable 2, the impact wheel 21 in a rotating state will contact the mesh plate 6. Since the impact wheel 21 is eccentrically installed on the support shaft 17, the impact wheel 21 will continue to impact the mesh plate 6, which is convenient for vibrating impurities on the mesh plate 6 off. Since the mesh plate 6 is made of soft material, the mesh plate 6 can undergo a small amount of elastic deformation, so that the mesh plate 6 can smoothly pass over the impact wheel 21 and stay away from the impact wheel 21, thereby realizing the normal movement of the mesh plate 6.

[0055] Furthermore, another support shaft 17 in the discharge elbow 13 is inclined, and the support shaft 17 passes through the discharge elbow 13 and is rotatably connected to each other. A first transmission wheel 23 is provided at the end of the support shaft 17, and a first transmission ring 22 is provided on the inner wall of the fixed outer ring 1, and the first transmission wheel 23 rolls on the first transmission ring 22.

[0056] In detail, when the turntable 2 performs a circular motion, it will drive the support shaft 17 and the first transmission wheel 23 to move synchronously, and the first transmission wheel 23 will roll on the first transmission ring 22, thereby driving the support shaft 17 and the structure thereon to perform a rotational motion.

[0057] Further, a second transmission ring 24 is provided on one end surface of the turntable 2, a second transmission wheel 25 is provided on the second transmission ring 24, a rotating column 26 is provided on the second transmission wheel 25, the rotating column 26 is rotatably mounted on a support seat 5 through a third support plate 27, a third transmission wheel 28 is provided at the end of the rotating column 26, a circular groove 29 is provided on the circumferential inner wall of the fixed outer ring 1, and the third transmission wheel 28 is rollingly mounted in the circular groove 29;

[0058] A support frame 30 is arranged on the outer wall of the fixed outer ring 1 , and a motor 31 is arranged on the support frame 30 . Fourth transmission wheels 32 are arranged on both the first support ring 3 and the second support ring 4 , and the motor 31 transmits power to the two fourth transmission wheels 32 .

[0059] In detail, when the turntable 2 performs a circular motion, the support seat 5 will drive the third transmission wheel 28 to roll on the inner wall of the circular groove 29 through the rotating column 26. At this time, the third transmission wheel 28 will drive the second transmission wheel 25 to rotate through the rotating column 26, and the second transmission wheel 25 will drive the turntable 2 to rotate through the second transmission ring 24. Of course, the rotation speed of the turntable 2 can be changed by changing the diameters of the second transmission wheel 25 and the third transmission wheel 28.

[0060] The support frame 30 can provide support for the motor 31, and the motor 31 drives the two fourth transmission wheels 32 to rotate, thereby driving the first support ring 3 and the second support ring 4 to move in a circular motion. The transmission between the motor 31 and the fourth transmission wheel 32 can be realized through conventional structures such as bevel gears and transmission shafts.

[0061] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
