Description

Technical Field

[0001] The present invention relates to the technical field of deodorization equipment, and specifically to a deodorization equipment for kitchen waste. Background Art

[0002] The deodorization equipment for kitchen waste is a special equipment for odor control and resource treatment in the process of catering waste treatment. Its core function is to pre-treat kitchen waste by physical, mechanical and other means, reduce the volatile malodorous gases (such as ammonia, hydrogen sulfide, etc.) generated by the retention of organic matter and microbial fermentation, and create low-load treatment conditions for the subsequent deodorization process. This type of equipment usually integrates functional modules such as solid-liquid separation, material crushing, and discharge control. By optimizing the material treatment process, it inhibits odor generation from the source and is a key front-end pre-treatment equipment in the catering waste treatment system.

[0003] In the prior art, the treatment process of the deodorization equipment for kitchen waste usually includes the following key links: First, the kitchen waste entering the equipment is diluted with water to improve the subsequent solid-liquid separation efficiency by reducing the material viscosity; then, the diluted material is subjected to solid-liquid separation by an extrusion or filtration device, and the liquid component is initially discharged to reduce the organic matter content; after the separated solid material is crushed, it is discharged from the equipment by gravity or mechanical conveying, and at the same time, a deodorization system is equipped to collect and purify the gas generated during the treatment process.

[0004] However, this process relies on water dilution to improve the separation effect, resulting in a relatively high water content in the solid material, which not only increases the subsequent treatment load, but also the residual water is prone to breed microorganisms, increasing the risk of odor generation; in addition, the traditional solid-liquid separation device is not sufficient for crushing blocky materials, and the problem of filter hole blockage occurs frequently, requiring frequent shutdown for cleaning, which affects the continuous operation efficiency of the equipment.

[0005] For this reason, we propose a deodorization equipment for kitchen waste. Summary of the Invention

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present invention.

[0030] Embodiment 1. The purpose of this embodiment is to promote the solution to the problem that the existing technology relies on adding water for dilution to improve the separation effect, resulting in a high moisture content of solid materials, which not only increases the subsequent processing load, but also the residual moisture is prone to breed microorganisms and exacerbate the risk of odor generation. Please refer to Figures 1 to 9 A deodorization device for kitchen waste, including a housing 1, an extrusion device 2 and a transmission assembly 3 are arranged in the housing 1. The extrusion device 2 is used to separate solid and liquid of kitchen waste. The extrusion device 2 includes a filter plate 22 and an extrusion plate 24. Under the action of the transmission assembly 3, the extrusion plate 24 squeezes and rubs the kitchen waste entering the housing 1, and the filter plate 22 is used to separate the solid and liquid of the kitchen waste after being squeezed and rubbed.

[0031] The extrusion device 2 includes a filter installation housing 21 installed on the inner wall of the housing 1. The filter plate 22 is installed in the filter installation housing 21. A driving motor 23 is connected above the extrusion plate 24 through the transmission assembly 3, and the driving motor 23 is installed on the top of the housing 1.

[0032] A rotating closed groove 26 is opened on one side of the extrusion plate 24, a rotating closed block 27 is rotatably connected in the rotating closed groove 26, a feeding port 25 is opened on one side of the extrusion plate 24, and a discharge port 28 is arranged on the side wall of the housing 1.

[0033] Through the structural design of the extrusion device 2, the kitchen waste entering the interior of the housing 1 through the feed inlet 25 can be subjected to an extrusion and extraction operation. The extrusion plate 24 performs a downward movement while executing a rotational movement. This combined motion form enables the extruded material to further undergo a rubbing and crushing process on the basis of being subjected to mechanical pressure, thereby realizing the refined treatment of kitchen waste and effectively improving the solid-liquid separation efficiency.

[0034] The specific working process is as follows: The kitchen waste enters the working cavity formed by the filter plate 22 and the extrusion plate 24 through the feed inlet 25. The driving motor 23, through the power transmission of the transmission assembly 3, causes the extrusion plate 24 to generate a combined motion trajectory of rotation and descent. During the downward movement of the extrusion plate 24, a directional extrusion force is applied to the kitchen waste in the cavity, prompting the liquid components in the material to be discharged through the filter holes of the filter plate 22. At the same time, the rotational movement of the extrusion plate 24 generates a shearing and tearing effect, breaking the large pieces of material into smaller particle sizes. This combined mechanism of extrusion and crushing ensures that during the extrusion and dehydration process, the solid-phase structure of the material is fully destroyed, and the liquid components can be separated and precipitated more efficiently, guaranteeing the optimized implementation of the solid-liquid separation process from the structural design level.

[0035] By improving the efficiency of solid-liquid separation, the moisture content of the solid residue can be greatly reduced, thereby reducing the residence time of organic matter inside the device, suppressing the anaerobic fermentation of microorganisms to produce volatile malodorous gases such as ammonia and hydrogen sulfide from the source, and reducing the load on the subsequent deodorization system.

[0036] The transmission assembly 3 includes a rectangular rod 31 connected to the output end of the driving motor 23. A connecting cylinder 32 is slidably connected to the outer side of the rectangular rod 31. The bottom of the connecting cylinder 32 is fixedly connected above the extrusion plate 24. The connecting cylinder 32 and the rectangular rod 31 are connected by a first spring 36.

[0037] A cylindrical empty barrel 33 is fixedly connected to the top of the housing 1. A track groove 34 is provided inside the cylindrical empty barrel 33. A slider 35 is slidably connected inside the track groove 34. The slider 35 is fixedly connected to the outer side wall of the connecting cylinder 32.

[0038] Through the collaborative design of sliding coupling and trajectory constraint of the transmission component 3, the conversion of the output motion form of the driving motor 23 is realized: the rectangular rod 31 at the output end of the driving motor 23 and the rectangular groove on the inner wall of the connecting cylinder 32 form a sliding fit structure, which allows the connecting cylinder 32 to slide freely along the axial direction while transmitting the rotational torque, forming a rigid transmission of rotational motion and a flexible fit mechanism of vertical displacement; the slider 35 on the outside of the connecting cylinder 32 is embedded in the trajectory groove 34 on the inner wall of the cylindrical empty barrel 33. When the connecting cylinder 32 rotates with the rectangular rod 31, the slider 35 is constrained by the curved surface of the trajectory groove 34, forcing the connecting cylinder 32 to generate an axial displacement while rotating, and finally forming the required rotational and descending compound motion of the pressing plate 24, providing a motion input with both pressure and shear force for material extrusion and kneading.

[0039] The rotating closing block 27 fixedly connected to the bottom of the connecting cylinder 32 is embedded in the rotating closing groove 26 of the pressing plate 24, forming a rotating sealing structure. During the process of garbage input, the feeding port 25 is in an open state. When the connecting cylinder 32 starts to rotate, the rotating closing block 27 rotates accordingly and completely blocks the channel after rotation. This closing design can complete the closing of the feeding port 25 before the pressing plate 24 starts to descend, effectively preventing the reverse ejection of materials during the extrusion process and ensuring the stable progress of the solid-liquid separation process in the working cavity.

[0040] Embodiment 2 is an explanatory description made on the basis of Embodiment 1. Specifically, please refer to Figures 1 to 9 , a crushing component 4 is arranged in the pressing plate 24. The crushing component 4 includes an empty groove 41 opened in the pressing plate 24. A sliding plate 42 is slidably connected in the empty groove 41. A crushing head 43 is fixedly connected to the bottom of the sliding plate 42. The crushing head 43 extends out of the pressing plate 24 under the action of the pressing shaft 45 and the driving inclined groove 46. The pressing shaft 45 is fixedly connected to the top of the sliding plate 42. The other end of the pressing shaft 45 is arranged in the driving inclined groove 46. The driving inclined groove 46 is opened at the bottom of the rotating closing block 27. The sliding plate 42 and the pressing plate 24 are connected by a second spring 44.

[0041] When the rotating closing block 27 rotates with the connecting cylinder 32 to completely block the feeding port 25, the driving inclined groove 46 opened at the bottom of the rotating closing block 27 forms mechanical contact with the wedge-shaped mating surface at the top end of the pressing shaft 45. Based on the motion conversion principle of the inclined plane mechanism, the inclination angle of the driving inclined groove 46 generates an axial component force on the pressing shaft 45, prompting it to slide downward. This linear motion is transmitted to the sliding plate 42 through a rigid connection structure, driving the crushing head 43 fixed on it to move downward synchronously until the bottom end of the crushing head 43 extends out of the working area at the bottom surface of the pressing plate 24.

[0042] At this time, the crushing head 43 forms a composite motion trajectory with the rotation of the extrusion plate 24: while making a circular motion around the central axis of the equipment, its tip exerts a combined shear force and impact force on the material. The cylindrical surface of the crushing head 43 is designed with a spiral cutting edge or a prismatic protrusion (the specific geometric parameters can be adaptively adjusted according to the material properties). Through the dual effects of shearing and crushing and extrusion and kneading when rotating into the material, the block material is further crushed, thereby improving the subsequent solid-liquid separation efficiency. The triggering of this mechanism is actually precisely matched with the motion phase of the extrusion plate 24, ensuring that the crushing head 43 intervenes in the work after the feed port 25 is completely closed, avoiding reverse splashing of the material and realizing the precise activation of the crushing function.

[0043] Example 3: This example is an explanation based on Example 2. For details, please refer to Figures 1 to 9 An inclined connection 5 is provided between the extrusion plate 24 and the filter plate 22, and the inclined connection 5 includes a vertical rod 51 arranged at the bottom of the extrusion plate 24, and the bottom of the vertical rod 51 is fixedly connected with a connecting shaft 53, and the side wall of the connecting shaft 53 is rotatably connected with a cross bar 52 through a connecting torsion spring 54, and the cross bar 52 is arranged in a lifting groove 56, and the lifting groove 56 is opened on the outside of the extrusion plate 24, and the top of the vertical rod 51 is slidably connected in an annular groove 58, and the annular groove 58 is opened at the bottom of the extrusion plate 24, and the side wall of the vertical rod 51 is fixedly connected with a sliding rod 510, and the other end of the sliding rod 510 is slidably connected in a vertical groove 59, and the vertical groove 59 is opened on the inner wall of the shell 1.

[0044] An insertion groove 55 is provided on the inner side of the filter installation shell 21 for inserting the vertical rod 51 . A tilting and rotating block 57 is provided on one side of the filter installation shell 21 close to the discharge port 28 for connecting the filter installation shell 21 and the filter plate 22 .

[0045] A vibration assembly 6 is provided at the bottom of the filter plate 22, and the vibration assembly 6 includes a connecting block 61 fixedly connected to the bottom of the filter plate 22, a striking center axis 64 is fixedly connected inside the connecting block 61, a side wall of the striking center axis 64 is rotatably connected to a striking rotating roller 63 through a striking torsion spring 65, and a striking rod 62 and a driving gear block 66 are fixedly connected to one side of the striking rotating roller 63.

[0046] A winding center shaft 68 is fixedly connected inside the connecting block 61, and the outer wall of the winding center shaft 68 is rotatably connected to a winding roller 610 through a winding torsion spring 69. A driving soft rack 67 is wound on the outer surface of the winding roller 610, and the driving soft rack 67 is meshed with the driving gear block 66. The other end of the driving soft rack 67 is fixedly connected to the inner wall of the filter mounting shell 21.

[0047] The vertical rod 51 at the bottom of the extrusion plate 24 forms a guide structure with the bottom connecting shaft 53 through the top annular groove 58, and the sliding rod 510 on the side wall of the vertical rod 51 cooperates with the vertical groove 59 to ensure that the vertical rod 51 slides linearly in the vertical direction. When the extrusion plate 24 descends, the vertical rod 51 moves downward accordingly, and the connecting shaft 53 is inserted into the insertion groove 55 of the filter mounting shell 21. At this time, the cross bar 52 is resisted by the surface of the filter plate 22 and rotates around the connecting shaft 53 to compress the connecting torsion spring 54; when the connecting shaft 53 enters the lifting groove 56, the cross bar 52 remains horizontal with the filter plate 22 under the action of the torsion spring reset force. After the solid-liquid separation is completed, the extrusion plate 24 rises and drives the vertical rod 51 to move upward, and the cross bar 52 resists the upper wall of the lifting groove 56, forcing the filter plate 22 to rotate around the inclined rotating block 57, so as to realize the gravity drainage of solid materials along the surface of the filter plate 22 to the discharge port 28.

[0048] The tilting rotating block 57 serves as the rotating fulcrum of the filter plate 22, and cooperates with the limiting guide of the lifting groove 56 to ensure that the filter plate 22 stably supports the material in the tilted state. When the extrusion plate 24 is completely reset, the filter plate 22 and the connecting shaft 53 lose mutual support, and the filter plate 22 automatically resets under its own gravity or the action of the additional torsion spring, ready for the next cycle. This structure avoids the retention and accumulation of materials on the surface of the filter plate 22, shortening the discharge time.

[0049] When the connecting block 61 at the bottom of the filter plate 22 moves with the tilt of the filter plate 22, the driving soft rack 67 on the winding roller 610 is gradually pulled out because one end is fixed to the inner wall of the filter mounting shell 21, and the toothed structure of the driving soft rack 67 is meshed with the driving tooth block 66 of the striking rotating roller 63, driving the striking rotating roller 63 to swing around the striking center axis 64, compressing the striking torsion spring 65; when the driving soft rack 67 is disengaged, the torsion spring reset force causes the striking rotating roller 63 to rotate rapidly, and the striking rod 62 installed thereon periodically strikes the bottom surface of the filter plate 22. The vibration of the striking rod 62 effectively removes fine particles and fibrous substances attached to the surface of the filter holes, avoiding clogging of the filter plate 22. At the same time, the vibration destroys the filter cake layer formed on the surface of the filter plate 22, accelerating the discharge of liquid residues between solid material particles, and with the inclined diversion, the moisture content of the material after solid-liquid separation can be further reduced. The energy storage design of the winding torsion spring 69 realizes the self-sufficiency of vibration energy without the need for an additional power source.

[0050] The tilting connection 5 and the vibration component 6 form an efficient discharge system through motion phase matching: during the rising process of the extrusion plate 24, the tilting mechanism first establishes the material diversion angle, and the vibration component 6 starts synchronously to clear the filter hole blockage; after the extrusion plate 24 is reset, the filter plate 22 automatically returns to the normal position to prepare for the next cycle of solid-liquid separation. This linkage design improves the discharge efficiency, significantly reduces the material residue in the equipment, inhibits the odor generated by microbial fermentation from the hardware level, and ensures the continuous and stable operation of the deodorization equipment.

[0051] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
