Description

Technical Field

[0001] The invention relates to the technical field of garbage disposal equipment, and in particular to an automatic solid-liquid separation kitchen garbage crusher. Background Art

[0002] The food waste disposers currently used in restaurants and large kitchens mainly utilize shredders, crushers or pulverizers to break up or pulverize the food waste.

[0003] The crusher is a centrifugal type, which crushes by rotating blades. It needs a lot of water as a medium to carry the materials and carry the garbage materials to flow, so there is a lot of water in the crushed garbage materials.

[0004] Shredders and crushers generally use two toothed rollers, which are usually equipped with multiple toothed blades. The blades are usually driven to rotate by the roller shaft. The blades are fixed on the roller shaft at intervals, and adjacent blades are separated by isolation sheets. The material is cut by the shear between adjacent blades, and the material is cut by the friction between the blade tooth tips and the isolation sheets. The two toothed rollers are usually arranged in parallel on the left and right. The material is put in from the top, crushed by the toothed rollers and falls to the bottom. During the crushing process, the residue and liquid cannot be effectively separated, and subsequent equipment is required to complete further solid-liquid separation.

[0005] Since shredders, crushers or pulverizers do not have the function of solid-liquid separation, the garbage materials need to be dried and dehydrated by centrifuges after crushing, or squeezed and dehydrated by screw presses. Whether it is centrifugal dehydration or squeezing dehydration, since two-stage treatment is required, the material passes through a long path inside the machine, and there will be a lot of residue, especially inside the screw press. There will be a lot of garbage squeezed into solid blocks, which is difficult to clean up. These garbage materials are easy to stink and rot, causing impact on the environment. Summary of the invention

[0006] The object of the present invention is to provide an automatic solid-liquid separation kitchen waste crusher to solve the above technical problems, which can achieve one-time crushing and solid-liquid separation, thereby improving the efficiency of kitchen waste treatment.

[0007] The technical problem solved by the present invention can be achieved by adopting the following technical solutions:

[0008] An automatic solid-liquid separation kitchen waste crusher comprises a chassis, a toothed roller and a filtering device. The chassis is provided with a feed port and a discharge port. The toothed roller comprises a plurality of toothed blades, a spacer and a roller shaft. The blades are fixedly arranged on the roller shaft at intervals, and adjacent blades are separated by a spacer. The blades on two interacting toothed rollers are arranged in correspondence with each other and inserted in parallel. The toothed roller comprises an upper toothed roller and a lower toothed roller. The upper toothed roller and the lower toothed roller are arranged in parallel with each other in an upper and lower dislocation, and the upper toothed roller is located in front of the lower toothed roller. The front interlaced part of the upper toothed roller and the lower toothed roller is lower than the highest point of the circumference of the lower toothed roller, so that the waste liquid generated when the upper toothed roller and the lower toothed roller are crushed flows out from the front of the lower toothed roller, and the residue generated when the upper toothed roller and the lower toothed roller are crushed is discharged from the rear of the lower toothed roller.

[0009] The rear part of the lower toothed roller is also equipped with a scraper plate, on which a plurality of scraper comb teeth are arranged. The scraper comb teeth and the blade of the lower toothed roller are in abutment with each other to scrape off the crushed residue.

[0010] It also includes a feed auxiliary toothed roller, which is located at the front end of the lower toothed roller, and a water leakage gap is left between the feed auxiliary toothed roller and the lower toothed roller.

[0011] The water leakage gap is the gap distance between the tooth tip of the blade between the feed auxiliary gear roller and the lower gear roller and the outer edge of the corresponding isolation plate. The spacing of the water leakage gap is 2~3mm. The water leakage gap is used for the waste liquid to flow and to achieve the barrier of residue.

[0012] The feed auxiliary gear roller and the upper gear roller rotate in opposite directions, and the upper gear roller and the lower gear roller rotate in opposite directions.

[0013] The gap between the upper and lower toothed rollers is the distance between the tip of the blade tooth and the outer edge of the corresponding isolation plate and the lateral distance between two adjacent blades on the upper and lower toothed rollers. The gap is a mechanical fit gap of the order of 0.1 mm, which is not conducive to the passage of waste liquid.

[0014] The filtering device is located below the feed auxiliary gear roller and the lower gear roller, and comprises a filter screen and a dredging sheet. The filter screen is provided with a plurality of filter holes, and the dredging sheet dredges the filter holes by rotating or moving in the filter holes.

[0015] The filter holes are long strip hole structures, and the filter holes are arranged along the length direction.

[0016] The gear roller is an integrated structure.

[0017] The toothed roller is a split structure, with the blade and the isolation sheet respectively sleeved on the roller shaft.

[0018] Compared with the prior art, the present invention has the following outstanding advantages and effects: through optimized design, the present invention can realize the crushing and solid-liquid separation of restaurant kitchen waste in one go, thereby reducing the processing time of restaurant kitchen waste and improving the processing efficiency. At the same time, there are less internal residues, which is convenient for overall cleaning.

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below with reference to specific diagrams.

[0031] Unless otherwise defined, the technical or scientific terms used herein shall have the usual meanings understood by persons with ordinary skills in the field to which the present invention belongs. The words "first", "second" and similar words used in the patent application specification and claims of the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. The words "front" or "rear" and similar words are defined in the direction that the food waste feed port is the front end and the residue discharge port is the rear end.

[0032] As shown in the figure, an automatic solid-liquid separation kitchen waste pulverizer provided by the present invention includes a chassis 1, a toothed roller 2 and a filtering device 3. The chassis 1 is provided with a feed port 11 and a discharge port 12. The toothed roller 2 includes a plurality of toothed blades 24, a spacer 25 and a roller shaft 26. The blades 24 are arranged on the roller shaft 26 at fixed intervals, and adjacent blades 24 are separated by the spacer 25. The blades 24 on the two interacting toothed rollers 2 are arranged to correspond to each other and to be inserted into each other.

[0033] The two interacting toothed rollers 2, i.e., the upper toothed roller 21 and the lower toothed roller 22 interact and cooperate with each other, and the feed auxiliary toothed roller 23 and the lower toothed roller 22 interact and cooperate with each other. Their cooperation relationship is that the blades 24 on the upper toothed roller 21 and the lower toothed roller 22 are arranged in a corresponding and interlocking manner, and the blades 24 on the feed auxiliary toothed roller 23 and the lower toothed roller 22 are arranged in a corresponding and interlocking manner.

[0034] The upper gear roller 21 and the feed auxiliary gear roller 23 are not in contact with each other.

[0035] Among them, the feed port 11 is used for pouring in food waste, and the discharge port 12 is divided into a residue discharge port 121 and a waste liquid discharge port 122 to discharge the food waste after solid-liquid separation; the toothed roller 2 is used to realize the crushing and solid-liquid separation of the food waste.

[0036] In this embodiment, the toothed roller 2 includes an upper toothed roller 21 and a lower toothed roller 22. The upper toothed roller 21 and the lower toothed roller 22 are arranged in parallel with each other in an up-down offset manner, and the upper toothed roller 21 is located in front of the lower toothed roller 22. The arrangement structure of the upper toothed roller 21 and the lower toothed roller 22 is optimized. Different from the horizontal transverse arrangement structure in the prior art, the up-down offset structure between the upper toothed roller 21 and the lower toothed roller 22 is utilized, and the front staggered portion of the upper toothed roller 21 and the lower toothed roller 22 is lower than the highest point of the circumference of the lower toothed roller 22, so that the waste liquid generated when the upper toothed roller 21 and the lower toothed roller 22 are crushed flows out from the front of the lower toothed roller 22, and the waste liquid generated when the upper toothed roller 21 and the lower toothed roller 22 are crushed flows out from the front of the lower toothed roller 22. The residue is discharged from the rear part of the lower gear roller 22, effectively realizing the solid-liquid separation of the food waste; usually, after the food waste is poured into the feed port 11, it enters the blades between the upper gear roller 21 and the lower gear roller 22 to be crushed. During this period, the waste liquid flows out through squeezing, crushing, etc., combined with the preferred position relationship between the upper gear roller 21 and the lower gear roller 22, the staggered part of the upper gear roller 21 and the lower gear roller 22 is lower than the highest point of the circumference of the lower gear roller 22, so as to avoid the waste liquid from flowing out backwards, and the waste liquid is discharged downwards first, and the remaining residue is continuously transmitted backwards after being crushed, thereby realizing the solid-liquid separation of the food waste.

[0037] In this embodiment, a scraper plate 4 is also provided at the rear of the lower tooth roller 22, and a plurality of scraper comb teeth 41 are provided on the scraper plate 4. The scraper comb teeth 41 and the blade 24 of the lower tooth roller 22 are in a state of being about to abut against each other to scrape off the crushed residues, wherein the "about to abut against each other" means being infinitely close but not forming contact, which is the commonly used mechanical matching gap.

[0038] Among them, the scraper plate 4 is used to connect with the residue discharge port 122 to facilitate the cleaning of residues; a discharge inclined plate 123 is provided in the solid discharge port 122, and the upper edge of the upper part of the discharge inclined plate 123 is attached to the outer tooth end of the scraper comb teeth 41, and the upper edge of the upper part of the discharge inclined plate 123 is not higher than the upper end surface of the scraper comb teeth 41.

[0039] In one embodiment, the upper tooth roller 21 is provided with a stripping plate 5, on which a plurality of stripping comb teeth 51 are provided. The stripping comb teeth 51 and the blades 24 on the upper tooth roller 21 are arranged to correspond to each other and to be inserted into each other, which is beneficial to the crushing and cleaning of the food waste.

[0040] In one of the preferred embodiments, it also includes a feed auxiliary toothed roller 23, which is located at the front end of the lower toothed roller 22, and a water leakage gap is left between the feed auxiliary toothed roller 23 and the lower toothed roller 22, and the feed auxiliary toothed roller 23 and the lower toothed roller 22 rotate in the same direction; the feed auxiliary toothed roller 23 is located at the feed port 11, and when the food waste is poured into the feed port 11, the waste liquid contained in the food waste is usually discharged through the water leakage gap and the filter device 3 first, and the remaining liquid food waste is transmitted backwards through the feed auxiliary toothed roller 23, and the feed auxiliary toothed roller 23 and the lower toothed roller 22 rotate in the same direction, preferably clockwise, and the food waste is continuously transmitted backwards until the upper toothed roller 21 and the lower toothed roller 22 intersect, and the crushing is completed. In combination with the above, the remaining waste liquid in the food waste flows forward and downward, and the residue is continuously transmitted backwards due to the drive of the lower toothed roller 22, and after the crushing is completed, it is transported to the residue discharge port 122 for discharge.

[0041] In any of the above embodiments, the preferred feeding auxiliary tooth roller 23 and the upper tooth roller 21 rotate in opposite directions to each other, so as to facilitate the backward transmission of the food waste after feeding and complete the preliminary crushing and separation. The upper tooth roller 21 and the lower tooth roller 22 rotate in opposite directions to achieve further crushing, extrusion, shearing and separation, so that the residue part is transmitted backward and the waste liquid part is discharged forward.

[0042] In one of the preferred embodiments, the water leakage gap is the gap distance between the tooth tip of the blade 24 and the outer edge of the corresponding isolation plate 25 between the feed auxiliary tooth roller 23 and the lower tooth roller 22. The spacing of the water leakage gap is 2~3mm. The water leakage gap is used for the flow of waste liquid and to achieve the barrier of residue, which is beneficial to achieve solid-liquid separation. The co-directional rotation between the feed auxiliary tooth roller 23 and the lower tooth roller 22, combined with the gap limitation, can prevent the residue from falling and achieve continuous backward transmission of the residue.

[0043] In one of the preferred embodiments, the water leakage gap is the horizontal spacing between the two adjacent blades 24 inserted between the feed auxiliary tooth roller 23 and the lower tooth roller 22. The spacing of the water leakage gap is 2~3mm. The water leakage gap is used for the flow of waste liquid and to achieve the barrier of residue, which is beneficial to achieve solid-liquid separation. By utilizing the same-direction rotation between the feed auxiliary tooth roller 23 and the lower tooth roller 22, combined with the gap limitation, the falling of residue can be avoided, and the continuous backward transmission of residue can be achieved.

[0044] In one of the preferred embodiments, a filtering device 3 is further included. The filtering device 3 is located below the feed auxiliary gear roller 23 and the lower gear roller 22. The filtering device 3 includes a filter screen 31 and a dredging sheet 321. The filter screen 31 is provided with a plurality of filter holes 311.

[0045] In one of the preferred embodiments, the dredging piece 321 dredges the filter hole 311 by rotating in the filter hole 311. Usually, a dredging piece rotating shaft 322 is also provided. The dredging piece rotating shaft 322 and the dredging piece 321 are combined to form a dredging device 32. The dredging piece 321 is elliptical or star-shaped. The dredging piece rotating shaft 322 is used to drive the dredging piece 321 to rotate so as to dredge the filter hole 311.

[0046] In other embodiments, the clearing piece 321 clears the filter hole 311 by moving back and forth in the filter hole 311. The filter hole 311 is preferably a long hole structure, and the filter holes 311 are arranged along the length direction. A crank-connecting rod device is usually provided to drive the clearing piece to move back and forth, wherein the clearing piece is usually provided with sharp angles, trapezoidal structures and the like, which are convenient for mobile clearing and use. The crank-connecting rod device drives the clearing piece to move back and forth along the filter hole 311, thereby clearing the filter hole 311. The crank-connecting rod device is a commonly used well-known technology and will not be described here.

[0047] In any of the above embodiments, the upper portion of the dredging sheet 321 preferably protrudes from the filter hole 311 .

[0048] The filtering device 3 is used to further filter the waste liquid, reduce the solid content in the waste liquid, and improve the solid-liquid separation effect; at the same time, combined with the unclogging device 32, the filter hole 311 can be unblocked to avoid clogging of the filter hole 311, thereby increasing the continuous use time of the filtering device 3 and reducing the cleaning frequency of the filter 31.

[0049] In one of the preferred embodiments, the gap between the upper tooth roller 21 and the lower tooth roller 22 is the distance between the tip of the blade tooth and the outer edge of the corresponding isolation plate and the lateral distance between two adjacent blades on the upper tooth roller 21 and the lower tooth roller 22. The gap is a mechanical fit gap of the order of 0.1 mm, which is not conducive to the passage of waste liquid.

[0050] In one preferred embodiment, the toothed roller 2 is an integral structure, wherein the blade 24 and the isolation sheet 25 are integrally formed with the roller shaft 26 or fixed by welding.

[0051] In one preferred embodiment, the toothed roller 2 is a split structure, and the blade 24 and the isolation sheet 25 are respectively sleeved on the roller shaft 26 and fixed by clamping, screw fastening, thread fastening, etc.

[0052] In any of the above embodiments, words such as "front" or "rear" and the like are defined according to the direction that the feeding of food waste is the front end and the discharging is the rear end.

[0053] The present invention can realize the crushing and solid-liquid separation of restaurant kitchen waste at one time through optimized design, thereby reducing the processing time of restaurant kitchen waste and improving the processing efficiency; at the same time, there are few internal residues, which is convenient for overall cleaning.

[0054] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features.
