Technical Field

[0001] This invention relates to the field of waste treatment technology, and more specifically, to a biological hydrolysis reactor for kitchen waste. Background Technology

[0002] Existing horizontal and vertical hydrolysis devices have high energy consumption due to high stirring resistance, high blade wear rate, and large maintenance workload. In particular, there is a certain stirring blind zone when the stirring blades are stirring, resulting in uneven hydrolysis reaction and reducing the effective volume of the reactor. Therefore, they are difficult to adapt to organic waste with high impurity content. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a biological hydrolysis reaction device for kitchen waste.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This invention discloses a biological hydrolysis reactor for kitchen waste, comprising an outer ring and an inner ring located at the center of the outer ring. A base plate connects the bottom of the outer ring and the inner ring, forming an annular reaction chamber. A material box is arranged on the left side of the outer ring, which is connected to the reaction chamber. A partition is arranged in the middle of the material box, with one end connected to the left side wall of the material box and the other end connected to the outer periphery of the inner ring. The partition divides the interior of the material box into a feeding chamber and a discharging chamber. A feeding valve is arranged at the connection between the feeding chamber and the reaction chamber, and a discharging valve is arranged at the connection between the discharging chamber and the reaction chamber. A connecting valve is arranged on the part of the partition located inside the reaction chamber. A rotating shaft is rotatably arranged inside the reaction chamber, and a sleeve is arranged on the rotating shaft. A pusher plate is installed on the outer periphery of the sleeve.

[0006] Furthermore, the two ends of the rotating shaft pass through the outer ring and the inner ring respectively, and a sealing sleeve is provided at the connection between the rotating shaft and the outer ring and the inner ring.

[0007] Furthermore, a support frame is provided on the outer periphery of the outer ring, and one end of the rotating shaft that protrudes from the outer ring is rotatably mounted inside the support frame.

[0008] Furthermore, a support base is connected inside the inner ring, and a transmission bevel gear is rotatably mounted on the support base. A drive motor is installed on one of the support bases, and the drive motor drives and connects to a driving bevel gear. The driving bevel gear meshes with the transmission bevel gear. A driven bevel gear is connected to the end of the rotating shaft that passes through the inner ring, and the driven bevel gear meshes with the transmission bevel gear.

[0009] Furthermore, two limiting plates are installed on the rotating shaft, and the sleeve is located between the two limiting plates. A limiting strip is connected to the outer circumference of the rotating shaft at the position between the two limiting plates. A guide groove that cooperates with the limiting strip is opened inside the sleeve. The sleeve can rotate with the rotating shaft. An adjustment mechanism is provided on the rotating shaft. The adjustment mechanism can drive the sleeve to move along the axial direction of the rotating shaft.

[0010] Furthermore, a rotating groove is provided inside the sleeve, which connects to one end of a rotating shaft located inside the inner ring. A lead screw is rotatably installed inside the rotating groove, and a lead screw motor is installed at the end of the rotating shaft located inside the inner ring. The lead screw motor drives the lead screw, and a lead screw nut block is installed on the lead screw. A guide hole is provided on the rotating shaft, which is set along the axial direction of the rotating shaft.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figures 1-5 The present invention discloses a biological hydrolysis reactor for kitchen waste, comprising an outer ring 2 and an inner ring 3 located at the center of the outer ring 2. A base plate 41 is connected between the bottoms of the outer ring 2 and the inner ring 3, forming an annular reaction chamber 1. A material box 4 is disposed on the left side of the outer ring 2, and the material box 4 is connected to the reaction chamber 1. A partition 5 is disposed in the middle of the material box 4, one end of which is connected to the left side wall of the material box 4, and the other end of which is connected to the outer periphery of the inner ring 3. The partition 5 divides the interior of the material box 4 into a feeding chamber 6 and a discharging chamber 7. A feeding valve 8 is disposed at the connection between the feeding chamber 6 and the reaction chamber 1, and a discharging valve 9 is disposed at the connection between the discharging chamber 7 and the reaction chamber 1. The feeding valve 8 and the discharging valve 9 are arc-shaped. A connecting valve 12 is disposed on the portion of the partition 5 located inside the reaction chamber 1. When the amount of organic waste is small, open the feed valve 8 and discharge valve 9, connecting the feed chamber 6 and discharge chamber 7 to the reaction chamber 1. Then close the connecting valve 12 to isolate the interior of the reaction chamber 1. Organic waste, microorganisms, and enzymes are fed from the feed chamber 6 into the reaction chamber 1. Inside the reaction chamber 1, the materials are mixed with the microorganisms and enzymes to complete biological hydrolysis. The hydrolyzed material can be discharged through the discharge chamber 7 for subsequent solid-liquid separation, thus utilizing both the solid and liquid phases.

[0024] When there is a large amount of organic waste, close the discharge valve 9 and the connecting valve 12, and open the feed valve 8 to transport the organic waste, bacteria, and enzymes from the feed chamber 6 into the reaction chamber 1.

[0025] Then close the feed valve 8 and open the connecting valve 12. The organic waste circulates within the reaction chamber 1, allowing the material to mix thoroughly with the bacteria and enzymes, and providing more time for biological hydrolysis, thus better converting the solid phase in the material into the liquid phase. After sufficient decomposition time, close the connecting valve 12 and open the discharge valve 9, allowing the hydrolyzed material to be discharged through the discharge chamber 7.

[0026] The partition 5 is provided with a guide plate 10 and a guide plate 21 at one end near the inner ring 3. The ends of the guide plates 10 and 21 near the inner ring 3 are bent away from the center. The bent guide plates 10 and 21 can guide the movement of organic waste in the reaction chamber 1, so that the organic waste can enter and leave the reaction chamber 1 better.

[0027] A rotating shaft 13 is rotatably mounted inside the reaction chamber 1, arranged radially along the chamber. A sleeve 14 is mounted on the rotating shaft 13, and a pusher plate 15 is installed on the outer periphery of the sleeve 14. Several rotating shafts 13 are evenly distributed within the reaction chamber 1. The rotating shafts 13 drive the pusher plates 15 to rotate via the sleeves 14. The pusher plates 15 can move organic waste within the reaction chamber 1 and can stir the organic waste, microorganisms, and enzymes, thereby mixing them for effective biodegradation. A support frame 16 is provided on the outer periphery of the outer ring 2. One end of the rotating shaft 13, extending out of the outer ring 2, is rotatably mounted within the support frame 16, which provides rotational support for the rotating shaft 13.

[0028] The two ends of the rotating shaft 13 pass through the outer ring 2 and the inner ring 3 respectively, and a sealing sleeve 21 is provided at the connection between the rotating shaft 13 and the outer ring 2 and the inner ring 3. The sealing sleeve 21 serves to seal and prevent material leakage.

[0029] like Figure 2 As shown, a support base 27 is connected inside the inner ring 3. A transmission bevel gear 28 is rotatably mounted on the support base 27. A drive motor 29 is mounted on one of the support bases 27. The drive motor 29 drives a driving bevel gear 30, which meshes with the transmission bevel gear 28. A driven bevel gear 25 is connected to the end of the rotating shaft 13 passing through the inner ring 3. The driven bevel gear 25 meshes with the transmission bevel gear 28. The drive motor 29 drives the driving bevel gear 30 to rotate, which in turn drives the meshing transmission bevel gear 28 to rotate. The transmission bevel gear 28 then drives each meshing driven bevel gear 25 to rotate, causing all rotating shafts 13 to rotate synchronously. The rotating shafts 13 drive the pusher plate 15 on the sleeve 14 to rotate, completing the mixing and pushing of materials.

[0030] Two limiting plates 17 are installed on the rotating shaft 13. A sleeve 14 is located between the two limiting plates 17. A limiting strip 18 is connected to the outer circumference of the rotating shaft 13 between the two limiting plates 17. A guide groove that mates with the limiting strip 18 is provided inside the sleeve 14. The cooperation between the limiting strip 18 and the guide groove allows the sleeve 14 to move axially along the rotating shaft 13 and rotate with the rotating shaft 13. An adjustment mechanism is provided on the rotating shaft 13, which can drive the sleeve 14 to move on the rotating shaft 13. The length of the pusher plate 15 cannot be less than the radial length of the reaction chamber 1, which would cause the material near the outer ring 2 and inner ring 3 to stagnate and not be effectively pushed. By changing the position of the sleeve 14 on the rotating shaft 13 through the adjustment mechanism, the sleeve 14 is shifted towards the outer ring 2 or inner ring 3, thereby stirring the material near the inner ring 3 and driving that part of the material to move. The adjusting mechanism periodically drives the sleeve 14 to move on the rotating shaft 13, thereby causing the pusher plate 15 to alternately approach the outer ring 2 or the inner ring 3 to compensate for the insufficient stirring of materials near the outer ring 2 and the inner ring 3.

[0031] like Figure 4 , Figure 5 As shown, a rotating groove 35 is provided inside the sleeve 14. The rotating groove 35 connects to one end of the rotating shaft 13 located inside the inner ring 3. A lead screw 36 is rotatably mounted inside the rotating groove 35. A lead screw motor 26 is installed at one end of the rotating shaft 13 located inside the inner ring 3. The lead screw motor 26 is fixedly mounted on the rotating shaft 13 and can rotate together with the rotating shaft 13. The lead screw motor 26 drives the lead screw 36. A lead screw nut block 37 is installed on the lead screw 36. A guide hole 39 is provided on the rotating shaft 13. The guide hole 39 is arranged along the axial direction of the rotating shaft 13. A connecting rod 38 is connected to the lead screw nut block 37. The connecting rod 38 passes through the guide hole 39 and connects to the inner wall of the sleeve 14.

[0032] A stop 40 is installed on the connecting rod 38, and the stop 40 is set against the inner wall of the rotating shaft 13 to ensure the sealing between the two. During the process of the lead screw 36 driving the lead screw nut block 37 to move and drive the sleeve 14 to move, the stop 40 can remain in the state of covering the guide hole 39, thereby preventing material from entering the rotating groove 35 through the guide hole 39.

[0033] like Figure 1 , Figure 3As shown, a mounting groove 24 is provided on the base plate 41, which is arranged radially along the reaction chamber 1. An aeration pipe 19 is installed in the mounting groove 24, and several aeration holes 31 are provided on the aeration pipe 19. A one-way valve 32 is installed above the aeration holes 31 to prevent impurities from entering the aeration pipe 19 from the aeration holes 31. An aeration pump 22 is installed inside the inner ring 3, and a rotary joint 23 is connected to the aeration pump 22. One end of the aeration pipe 19 passes through the inner ring 3 and is inserted into the rotary joint 23. The aeration pump 22 intermittently pumps gas into the reaction chamber 1 through the aeration holes 31 on the aeration pipe 19 to perform aeration, and performs gas agitation on the material outside the stirring area of ​​the pusher plate 15, assisting and supplementing the mechanical agitation of the pusher plate 15, so that the material is mixed with the bacteria and enzymes, and the decomposition effect is enhanced.

[0034] The aeration pipe 19 is rotatably connected to the rotary joint 23, with the end of the aeration pipe 19 away from the rotary joint 23 extending through the outer ring 2 and sealed. Rotating the aeration pipe 19 through the end extending through the outer ring 2 adjusts the angle of the aeration holes 31 on the aeration pipe 19, allowing aeration to enter the reaction chamber 1 from different directions. Different initial angles of airflow generate different vortices, thus agitating the material in the reaction chamber 1 in different directions and achieving a better auxiliary stirring effect.

[0035] The waste may contain impurities such as glass and sand. These impurities are relatively heavy and will move along the bottom of the reaction chamber 1, colliding with the aeration pipe 19 and causing damage. Along the material flow direction, a baffle plate 20 is installed on the bottom plate 41 in front of the aeration pipe 19. The baffle plate 20 is inclined, with the end of the baffle plate 20 closer to the aeration pipe 19 being higher than the end farther away. One end of the baffle plate 20 extends above the mounting groove 24, thus covering most of the aeration pipe 19. The baffle plate 20 ensures that impurities such as glass and sand move along the upper surface of the baffle plate 20, passing over the aeration pipe 19 without causing damage.

[0036] A screen plate 33 is provided on the baffle plate 20 near the end connected to the bottom plate 41. The screen plate 33 is perpendicular to the baffle plate 20 and can intercept larger impurities, preventing these impurities from falling onto the aeration pipe 19 due to their large mass and rapid decline in mass as they pass through the aeration pipe 19, thus effectively protecting the aeration pipe 19.

[0037] A receiving trough 34 is provided on the bottom plate 41 below the screen plate 33 to collect impurities trapped by the screen plate 33. A interception plate can also be provided on the top of the receiving trough 34. The interception plate has interception holes with a larger opening at the top and a smaller opening at the bottom. The shape of the interception holes makes it difficult for impurities that enter the receiving trough 34 through the interception holes to leave the receiving trough 34 through the screen holes. These impurities will not move on the bottom plate 41, thereby avoiding damage to the aeration pipe.

[0038] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
