Description

Technical Field

[0001] This invention relates to the field of kitchen waste biodegradation technology, specifically a high-temperature biodegradation device for kitchen waste. Background Technology

[0002] Currently, in traditional kitchen waste treatment technologies, existing equipment mostly uses single-stage crushing. The crushed waste particles are uneven in size, and some large particles are prone to clogging subsequent processing stages, resulting in low crushing efficiency. Conventional pressure filtration methods are difficult to completely separate the free liquid in the waste, and the residual liquid is prone to fermentation and odor production during subsequent processing, and may even breed harmful microorganisms. The solid material after pressure filtration is prone to forming large clumps due to accumulation and compaction, which can easily cause local accumulation when directly fed into degradation equipment, affecting the biodegradation efficiency.

[0003] Therefore, it is necessary to provide a high-temperature biodegradation device for kitchen waste to solve the problems mentioned in the background art. Summary of the Invention

[0015] The suction pipe is installed at the top of the crushing chamber and connected to the shell cavity.

[0016] As a preferred embodiment of the present invention, the outer wall of the pressure cylinder is provided with a sealing sleeve located at the lower end of the guide hole ring.

[0017] As a preferred embodiment of the present invention, the upper sidewall of the sealing sleeve and the wall of the feeding chamber are provided with an overlapping annular surface with a height of h.

[0018] As a preferred embodiment of the present invention, the pressure cylinder is provided with a lifting groove that slides with the inclined cylinder, and the lower end of the inclined cylinder is connected to the bottom of the lifting groove by a spring.

[0019] As a preferred embodiment of the present invention, the lower end of the push rod is provided with a ball bearing that contacts the inclined cylinder.

[0020] As a preferred embodiment of the present invention, the discharge device includes:

[0021] The column is set in the biodegradation box, with a stator and a rotating base fixed at its upper end;

[0022] The top material cylinder is slidably sleeved on the upper end of the column and connected to the rotating seat through spring three. Its inner cylinder cavity is equipped with a rotor coaxial with the stator. Its upper end is equipped with a lower pressing material cavity to cooperate with the top material block.

[0023] As a preferred embodiment of the present invention, a temperature control ring is provided in the wall of the material transfer cylinder.

[0024] As a preferred embodiment of the present invention, the upper end of the crushing box is provided with a feed inlet.

[0025] Compared with the prior art, the present invention provides a high-temperature biodegradation device for kitchen waste, which has the following beneficial effects:

[0026] In this invention, a continuous pressing device, through the reciprocating motion of the pressing cylinder and the suction action of the draining device, achieves continuous pressing and filtration of crushed waste and separation of liquid. When the pressing cylinder presses down, it blocks the connection between the upper and lower pressing chambers, compacting the waste in the lower pressing chamber. When the pressing cylinder moves up, it connects the two chambers, allowing new waste to enter the lower pressing chamber, forming a continuous cycle of guiding, pressing, and draining, which greatly improves the processing efficiency. At the same time, the suction device quickly discharges the squeezed liquid, avoiding liquid residue and reducing subsequent odor generation, thus achieving continuous pressing and efficient solid-liquid separation.

[0027] In this invention, the overlapping annular structure of the sealing sleeve and the guide hole ring utilizes the negative and positive pressure effects generated by the up-and-down movement of the pressure cylinder. That is, when moving upward, the negative pressure accelerates the waste to penetrate the material hole and enter the feeding chamber, while when moving downward, the positive pressure backflushs the residual waste back into the crushing box, flushing the material hole to avoid blockage. At the same time, it improves the contact efficiency between the waste in the crushing box and the crushing blade, further optimizing the crushing effect.

[0028] In this invention, the rotating grinding action of the top material block of the discharge device grinds the compacted columnar solid material in the lower pressure chamber into small particles, avoiding large clumps from being directly put into the degradation box. The centrifugal dispersion action of the scraping strips makes the ground solid material evenly dispersed in the biodegradation box, increasing the contact area between the biological flora and the waste, accelerating the degradation reaction, thereby uniformly discharging and grinding to prevent clumping.

[0034] Reference Figures 1-4 This invention provides a technical solution: a high-temperature biodegradation device for kitchen waste, comprising:

[0035] The biodegradable box 1 has a material transfer cylinder 2 connected to its upper end. The material transfer cylinder 2 is provided with a material transfer chamber 22 and a material pressing chamber 21. The material transfer chamber 22 is provided with a material guide hole ring 4 at its upper end. The material transfer chamber 22 is provided with a material discharge device 11 for regulating the discharge of material from the material pressing chamber 21.

[0036] Crushing box 3 is installed at the upper end of conveyor cylinder 2;

[0037] The motor 6 is installed on the upper end of the crushing box 3, and the lower end of the motor is connected to the rotating shaft 5. The outer wall of the rotating shaft 5 is provided with crushing blades 7. The lower end of the rotating shaft 5 is provided with a continuous pressing device 9 located in the material conveying cylinder 2, and the continuous pressing device 9 is also provided with a draining device 10.

[0038] Specifically, the pulverizing chamber 3 is used to hold solid kitchen waste. The rotating shaft 5 is located at the center of the pulverizing chamber 3. The guide hole ring 4 is coaxially arranged with the rotating shaft 5 and located outside the guide hole ring 4. The rotating shaft 5 is driven to rotate by the motor 6, which in turn drives the pulverizing blades 7 to pulverize the solid kitchen waste. The guide hole ring 4 has holes on its surface for discharging the pulverized kitchen waste. The size of these holes is set according to the required size range of the pulverized solid kitchen waste. Therefore, when the size of the pulverized kitchen waste is smaller than the size of the holes, it can be fed into the upper feeding chamber 22 through the holes, and then into the lower feeding chamber 21. The discharge device 11 can lift the lower end of the lower pressing chamber 21, allowing the kitchen waste entering the lower pressing chamber 21 to accumulate continuously. The continuous pressing device 9 then circulates and presses the kitchen waste entering the lower pressing chamber 21. During the circulating pressing process, the liquid discharge device 10 sucks out the liquid discharged by the squeezed kitchen waste to separate the solid and liquid materials and obtain the solid kitchen waste. At the same time, the discharge device 11 can also discharge the compacted solid kitchen waste in the lower pressing chamber 21, so that the obtained solid kitchen waste is dispersed into the biodegradation tank 1 for biodegradation.

[0039] In this embodiment, the continuous pressing device 9 includes:

[0040] The upper end of the lifting cylinder 91 is connected to the inner wall of the guide hole ring 4;

[0041] The pressure cylinder 92 is axially slidably connected to the lifting cylinder 91. Its upper end is connected to the upper end of the lifting cylinder 91 by a spring 93. An inclined cylinder 94 is installed in the pressure cylinder 92, and a pressure block 99 that cooperates with the lower pressure chamber 21 is installed at its lower end.

[0042] The turntable 95 is rotatably connected to the upper end of the lifting cylinder 91 and passes through the inner hole of the guide hole ring 4. Its lower end is provided with a top rod 96 that contacts the inclined surface of the inclined cylinder 94.

[0043] Specifically, in combination Figure 4As shown, when the rotating shaft 5 rotates, it drives the turntable 95 to rotate synchronously. Therefore, when the turntable 95 rotates, it drives the push rod 96 to move circumferentially. The lower end of the push rod 96 contacts the inclined surface of the pressing 94, and with the cooperation of the spring 93, the inclined cylinder 94 moves up and down reciprocally, thereby driving the pressing cylinder 92 to move up and down reciprocally. The pressing block 99 at the lower end of the pressing cylinder 92 moves up and down reciprocally, thereby circulating and pressing the kitchen waste in the lower pressing chamber 21. It should be noted that when the pressing block 99 moves to its maximum displacement, the pressing block 99... The lower end is located in the feeding chamber 22. That is to say, at this time, the feeding chamber 22 and the pressing chamber 21 are in a connected state so that the kitchen waste in the feeding chamber 22 can be introduced into the pressing chamber 21. When the pressing block 99 gradually moves down, the pressing block 99 will gradually enter the pressing chamber 21. After the lower end of the pressing block 99 enters the pressing chamber 21, the connection between the feeding chamber 22 and the pressing chamber 21 is blocked. The pressing block 99 presses the kitchen waste in the pressing chamber 21, thereby continuously guiding and pressing the kitchen waste in the pressing chamber 21.

[0044] In this embodiment, the draining device 10 includes:

[0045] The housing 102 is rotatably sleeved on the outer wall of the rotating shaft 5, and the rotating shaft 5 is provided with a shaft cavity 51 and a through hole 52 for connecting the shaft cavity 51 with the housing cavity of the housing 102.

[0046] The feed tube 103 is connected to the shaft cavity 51 at its upper end and slides into the liquid guiding cavity 922 in the pressure cylinder 92 at its lower end. The pressure block 99 is provided with a collection cavity 991 connected to the liquid guiding cavity 922 and a suction cavity 992 connected to the collection cavity 991. The lower end of the suction cavity 992 is provided with filter holes 993.

[0047] The suction pipe 101 is installed on the upper end of the crushing box 3 and connected to the cavity of the shell 102.

[0048] Specifically, in combination Figure 2 As shown, the suction pipe 101 is connected to an external suction device, the housing 102 rotates on the outer wall of the rotating shaft 5 so that the rotating shaft 5 can rotate independently, and the lower end of the guide pipe 103 slides in the liquid guiding cavity 922 so that the pressure cylinder 92 can move up and down. The guide pipe 103 is also in the liquid guiding cavity 922 at all times, so that the drainage device 10 can still operate under the condition that the continuous pressing device 9 is running. Therefore, when the suction device sucks the suction pipe 101, it causes the suction cavity 922 to generate negative pressure, so that the liquid at the lower end of the filter hole 993 enters the suction cavity 922 and is guided into the collection cavity 991, then into the liquid guiding cavity 922, and then sequentially into the guide pipe 103 and the housing cavity of the housing 102, and enters the suction pipe 101 through the through hole 52. After being discharged and collected by the suction device, the liquid in the solid material of kitchen waste is discharged.

[0049] In this embodiment, the outer wall of the pressure cylinder 92 is provided with a sealing sleeve 98 located at the lower end of the guide hole ring 4.

[0050] Specifically, when the pressure cylinder 92 moves upward to its maximum displacement, the sealing sleeve 98 seals the material hole of the guide hole ring 4. At this time, the feeding of kitchen waste in the crushing box 3 into the feeding chamber 22 is temporarily blocked, so that the kitchen waste in the crushing box 3 can be temporarily retained in the crushing box 3 for crushing, thereby improving the crushing efficiency and crushing effect of the kitchen waste in the crushing box 3, and forming the kitchen waste in the crushing box 3 to be fed into the feeding chamber 22 in an intermittent manner.

[0051] In this embodiment, the upper sidewall of the sealing sleeve 98 and the wall of the feeding chamber 22 have an overlapping annular surface with a height of h.

[0052] Specifically, by forming a coincident annular surface of height h, the sealing sleeve 98 can create a negative pressure condition within the coincident annular surface region. When the sealing sleeve 98 moves downward, this region generates suction in the direction of the guide hole ring 4, allowing kitchen waste in the pulverizing chamber 3 to penetrate the material holes of the guide hole ring 4 and enter the feeding chamber 22. This improves the efficiency and smoothness of the kitchen waste being fed from the pulverizing chamber 3 into the feeding chamber 22, and also increases the rate at which the kitchen waste penetrates the material holes of the guide hole ring 4, thereby reducing the clogging rate of the material holes of the guide hole ring 4. When the sealing sleeve 98 moves upward, this region can create a pressurized condition. This generates a thrust in the direction of the guide ring 4, so that the kitchen waste remaining in this area can flow back into the crushing box 3 through the material holes penetrating the guide ring 4. The kinetic energy of the backflowing kitchen waste can flush the material holes of the guide ring 4, thereby impacting the kitchen waste in and above the material holes of the guide ring 4. This has an upward impact and unblocking effect on the blocked material holes, thereby reducing the blockage effect of the material holes of the guide ring 4. At the same time, it is beneficial to guide the kitchen waste at the bottom of the crushing box 3 upward, improve the contact efficiency between the kitchen waste and the crushing blade 7, and thus improve the crushing efficiency of the kitchen waste.

[0053] In this embodiment, the pressure cylinder 92 is provided with a lifting groove 921 that slides with the inclined cylinder 94, and the lower end of the inclined cylinder 94 is connected to the bottom of the lifting groove 921 by a spring 97.

[0054] Specifically, by setting the second spring 97, the synchronization between the inclined cylinder 94 and the pressure cylinder 92 can be delayed, so that the pressure cylinder 92 can press the kitchen waste more stably and detach from the kitchen waste.

[0055] In this embodiment, the lower end of the push rod 96 is provided with a ball bearing 961 that contacts the inclined cylinder 94, so as to reduce the friction between the push rod 96 and the inclined surface of the inclined cylinder 94, and improve the service life and smooth operation.

[0056] In this embodiment, the discharge device 11 includes:

[0057] A column 111 is installed in the biodegradation box 1, with a stator 112 and a rotating base 113 fixed at its upper end;

[0058] The top material cylinder 114 is slidably sleeved on the upper end of the column 111 and connected to the rotating seat 113 through the spring 115. Its inner cylinder cavity is equipped with a rotor 116 coaxial with the stator 112. Its upper end is equipped with a lower pressing chamber 21 to cooperate with the top material block 117. The upper end of the top material block 117 is equipped with a scraping strip 118.

[0059] Specifically, through the setting of spring 3 115, the top material cylinder 114 initially places the top material block 117 in the lower pressing chamber 21, which has a sealing effect on the lower end of the lower pressing chamber 21, so that the kitchen waste in the lower pressing chamber 21 can accumulate. As the amount of kitchen waste in the lower pressing chamber 21 increases and under the continuous pressing action of the continuous pressing device 9, the kitchen waste in the lower pressing chamber 21 can form a columnar compacted kitchen waste, which gradually presses against the top material block 117, causing the top material block 117 to move downward. When the top material block 117 moves downward and disengages from the lower pressing chamber... When the lower end of 21 is reached, the lower end of rotor 116 begins to overlap with stator 112. As the top material block 117 moves down and moves further away from the lower end of the pressing chamber 21, the greater the overlap between the lower end of rotor 116 and stator 112, the greater the overlap. The stator 112 can then drive rotor 116 to rotate. The greater the overlap, the greater the power of the stator 112 to drive rotor 116. At this time, the rotating top material block 117 and scraper 118 perform rotary grinding on the lower end surface of the compacted kitchen waste to eliminate it. The ground kitchen waste solids are dispersed into the biodegradation tank 1 for degradation under the action of centrifugation.

[0060] In this embodiment, a temperature control ring 8 is provided in the wall of the conveying cylinder 2 to treat the kitchen waste at high temperature.

[0061] In this embodiment, the upper end of the crushing box 3 is provided with a feed inlet 31 so as to introduce kitchen waste into the crushing box 3.

[0062] In practice, kitchen waste is fed into the crushing box 3 through the inlet 31, the suction pipe 101 is connected to the external suction equipment, the motor 6 is started to drive the rotating shaft 5 to rotate, the suction equipment is started to suck up the suction pipe 101, the stator 112 is energized, the temperature control ring 8 is started to regulate the temperature, the crushing blade 7 crushes the kitchen waste in the crushing box 3, the continuous pressing device 9 continuously presses the kitchen waste in the lower pressing chamber 21, the liquid draining device 10 drains the liquid in the kitchen waste, the discharge device 11 grinds and disperses the compacted kitchen waste, and the biodegradation box 1 degrades the dispersed solid kitchen waste, thus enabling high-temperature biodegradation treatment of kitchen waste.

[0063] The above description is merely a preferred embodiment of the invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
