In the prior art, the treatment of food waste is carried out by crushing, squeezing and drying.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment: The present invention provides a centrifugal kitchen waste dehydrator, such as Figure 1-3 As shown, it includes a rotary drive mechanism 1, a spray mechanism 2, a filter screen 3, an auger 4, a liquid collecting box 5, a rotating seat 6, a tail cover 7, a feed inlet 8 and a filter screen mounting seat 9. The bottom of the liquid collecting box 5 is fixedly installed on the ground by supporting legs. The bottom of the liquid collecting box 5 is an inclined structure, and a liquid outlet pipe 5a is provided at the bottom of the liquid collecting box 5. The sewage discharged along the filter screen 3 will flow along the bottom inclined surface of the liquid collecting box 5 and finally be discharged along the liquid outlet pipe 5a. The rotating seat 6 is fixedly installed on one side of the liquid collecting box 5, and the tail cover 7 is fixedly installed on the other side of the liquid collecting box 5. The filter screen mounting seat 9 is rotatably connected with the rotating seat 6. The filter screen 3 is fixedly installed on the filter screen mounting seat 9, so that the filter screen 3 can be rotated by the support of the filter screen mounting seat 9. One end of the auger 4 passes through the filter screen mounting seat 9 and is rotatably connected thereto. The other end of the auger 4 rotates with the tail cover 7, so that the auger 4 is supported and rotated, and when the auger 4 or the filter screen mounting seat 9 rotates, they will not drive each other to rotate. The rotary drive mechanism 1 includes a primary transmission 1a and a secondary transmission 1b, and the rotation speed of the secondary transmission 1b is greater than that of the primary transmission 1a. The primary transmission 1a is fixedly connected to the filter screen mounting seat 9, that is, the primary transmission 1a can drive the auger 4 to rotate when working. The secondary transmission 1b is fixedly connected to the auger 4, that is, the secondary transmission 1b can drive the auger 4 to rotate. The speed of the auger 4 when rotating can be faster than the speed of the filter screen 3, ensuring that the food waste between the filter screen 3 and the auger 4 can be pushed outward along the inside of the filter screen 3. The spray mechanism 2 is fixedly installed on the auger 4, and the spray mechanism 2 is used to spray high-pressure water toward the filter screen 3, and the sprayed high-pressure water flow is in a flat umbrella shape. The main purpose of the filter screen 3 being driven to rotate is to prevent the debris of the food waste from clogging the mesh of the filter screen 3, because each position of the filter screen 3 in the rotating state can contact the high-pressure water flow, and the filter screen can be cleaned in time by the high-pressure water flow. The bottom of the tail cover 7 is provided with a slag outlet 7a, and the spiral blades of the auger 4 are inserted in the slag outlet 7a, so that the garbage discharged along the auger 4 can be discharged along the slag outlet 7a. Among them, the outer edge of the auger 4 is in contact with the inner edge of the filter 3, so that the food waste can be pushed. The middle part of the auger 4 is provided with a discharge port 4b, and the discharge port 4b is located in the wrapped area of ​​the filter 3. One end of the auger 4 is provided with a feed port 4a. The area from the feed port 4a to the discharge port 4b of the auger 4 is a hollow structure. One end of the feed port 8 is connected to the feed port 4a, and the other end of the feed port 8 is connected to the garbage discharge pipe. The feed port 8 is fixedly connected to the liquid collecting box 5 through a screw rod. The food waste generated by the user will enter the feed port 4a along the feed port 8, and will be squeezed out along the discharge port 4b along the hollow area, and finally enter the middle part of the filter 3 and the auger 4.

[0034] It should be noted that the spray mechanism 2 not only cleans the filter 3, but also cleans the kitchen waste, reducing grease and other pollutants on the waste, that is, the subsequent corruption odor of the waste.

[0035] Among them, after the dehydrator is not used every day, since the filter screen 3 is in a closed structure, the kitchen waste remaining in the filter screen 3 cannot be discharged, and these wastes will cause biofilm to form on the filter screen 3 in summer, clogging the mesh, and the inside of the dehydrator will stink and breed insects, which is not conducive to the hygiene of the kitchen. For this reason, Figure 3-5 As shown, the filter 3 includes a left half net 3a and a right half net 3b, and both the left half net 3a and the right half net 3b can be horizontally slidably mounted on the filter mounting seat 9. A separation mechanism 10 is provided on the outer side of the left half net 3a and the right half net 3b. The two separation mechanisms 10 are used to separate the left half net 3a and the right half net 3b outwardly, wherein: Figure 3 This is the combined state of the left half net 3a and the right half net 3b before separation. Figure 4 The left half net 3a and the right half net 3b are separated. The left half net 3a and the outer edge of the right half net 3a are provided with a metal frame, and the metal frame is used to ensure the stability of the structure. Each separation mechanism 10 includes an arc-shaped slide bar 10a, an arc-shaped slide rail 10b, an arc-shaped slide bar 2 10c, an arc-shaped slide rail 2 10d, a connecting plate 10e, an external pulling mechanism 10f and a locking switching mechanism 10h. Now, the structure of the separation mechanism 10 at the corresponding position of the left half net 3a is illustrated as follows: the arc-shaped slide bar 10a is fixedly installed on the outer edge of the left half net 3a, and the arc-shaped slide bar 10c is fixedly installed on the outer edge of the left half net 3a. The arc slide bar 10a is slidably connected to the arc slide rail 10b, the arc slide rail 10b and the arc slide bar 2 10c are both fixedly connected to the connecting plate 10e, the arc slide bar 2 10c is rotatably connected to the arc slide rail 2 10d, the locking switching mechanism 10h is fixedly installed on the connecting plate 10e, the locking switching mechanism 10h is used to fix the connecting plate 10e with the external pulling mechanism 10f or the left half net 3a, the external pulling mechanism 10f is fixedly installed on the liquid collecting box 5, and the external pulling mechanism 10f is used to pull the arc slide rail 2 10d outward;

[0036] When the left half net 3a and the right half net 3b are in a closed state, the external pulling mechanism 10f is in an initial state, and the axis of the arc-shaped slide bar 10a is coaxially arranged with the axis of the auger 4, so that when the left half net 3a and the right half net 3b rotate, the arc-shaped slide bar 10a can be driven to rotate along the arc-shaped slide rail 10b, thereby ensuring the rotation of the filter 3 in a closed state. The locking switching mechanism 10h is fixedly connected to the external pulling mechanism 10f, so that the arc-shaped slide bar 10c and the arc-shaped slide rail 10d are connected and cannot rotate with each other, and the arc-shaped slide bar 10a can rotate with the arc-shaped slide rail 10b.

[0037] When the left half net 3a and the right half net 3b are in a separated state, the external pulling mechanism 10f pulls the arc slide rail 10d to move outward, and the axis of the arc slide bar 10c is coaxially arranged with the axis of the auger 4, so that when the left half net 3a and the right half net 3b rotate, the arc slide bar 10c can be driven to rotate along the arc slide rail 10d, thereby ensuring the rotation of the filter 3 in the separated state. The locking switching mechanism 10h is fixedly connected to the left half net 3a, so that the arc slide rail 10b and the arc slide bar 10a are connected and cannot rotate with each other, and the arc slide bar 10c can rotate with the arc slide rail 10d.

[0038] Among them, since the left half net 3a and the right half net 3b are both slidably connected to the filter mounting seat 9, when the left half net 3a and the right half net 3b are in a separated state, the filter mounting seat 9 can still drive the left half net 3a and the right half net 3b to rotate, and there is no need to set up an additional device to drive the left half net 3a and the right half net 3b in the separated state to rotate.

[0039] Among them, Figure 5 As shown, a plurality of plug blocks 3b1 are fixedly provided on the right half net 3b, and a snap-in hole for horizontal insertion of the plug blocks 3b1 is fixedly provided on the left half net 3a. In this way, the stability of the left half net 3a and the right half net 3b in the closed state can be increased.

[0040] In order for the filter screen mounting seat 9 to drive the left half screen 3a and the right half screen 3b to rotate when in the separated state, Figure 6 As shown, the filter screen mounting seat 9 includes a rotating tube 9a and a rotating disk 9b, the rotating tube 9a is rotatably connected to the rotating seat 6, the rotating disk 9b is fixedly installed at the end of the rotating tube 9a, and two symmetrically distributed plug blocks 9c are arranged on the outer edge of the rotating disk 9b. The left half net 3a and the right half net 3b are fixedly provided with a collar, and the collar is sleeved on the outer edge of the plug block 9c, that is, the left half net 3a and the right half net 3b are both slidably connected to the filter screen mounting seat 9. When the left half net 3a and the right half net 3b are in a separated state, the plug block 9c and the collar remain connected. When the rotating tube 9a rotates, the left half net 3a and the right half net 3b are driven to rotate through the plug block 9c and the rotating disk 9b. Among them, when the left half net 3a and the right half net 3b are in a closed state, the inner edges of the left half net 3a and the right half net 3b fit with the outer edge of the rotating disk 9b to achieve sealing.

[0041] In order to realize that the outer pulling mechanism 10f can pull the arc-shaped slide rail 10d to move outward, as shown in FIG. Figure 7As shown, the outward pulling mechanism 10f includes an electric push rod 10f1, a mounting plate 10f3 and two guide pillars 10f2, the second arc slide rail 10d is fixedly connected to the mounting plate 10f3, one end of the two guide pillars 10f2 is fixedly connected to the mounting plate 10f3, the other end of the guide pillar 10f2 passes through the side wall of the liquid collecting box 5 and is slidably connected thereto, the electric push rod 10f1 is fixedly installed on the liquid collecting box 5, and the output end of the electric push rod 10f1 is fixedly connected to the guide pillar 10f2 through the connecting plate. By controlling the electric push rod 10f1 to work, the electric push rod 10f1 will pull the mounting plate 10f3 to move outward through the guide pillar 10f2, that is, pull the left half net 3a to move outward through the second arc slide rail 10d.

[0042] In order to realize that the locking switching mechanism 10h can switch the connection with the left half net 3a or the outer pulling mechanism 10f, for this purpose, Figure 8 As shown, the locking switching mechanism 10h includes an insertion shaft 10h1, a guide ring 10h2, a retaining ring 10h3 and a linear displacer 11. The guide ring 10h2 is fixedly mounted on the connecting plate 10e, and the linear displacer 11 is fixedly mounted in the guide ring 10h2. The linear displacer 11 is used to promote the bidirectional linear motion of the insertion shaft 10h1. The retaining ring 10h3 is fixedly arranged on the left half net 3a, and the guide ring 10h2 is opened on the mounting plate 10f3. When the left half net 3a and the right half net 3b are in a closed state, the end of the insertion shaft 10h1 is inserted into the insertion hole 10h4. At this time, it means that the external pulling mechanism 10f is in an initial state, and the arc-shaped slide rail 10d and the connecting plate 10e cannot slide against each other. When the left half net 3a and the right half net 3b are in a separated state, the end of the plug shaft 10h1 is inserted into the clamp ring 10h3, and at this time, the arc-shaped slide bar 10a and the arc-shaped slide rail 10b cannot slide against each other. It should be noted that when the plug shaft 10h1 is still located before the clamp ring 10h3 is separated, the other end of the plug shaft 10h1 has been inserted into the socket 10h4, so as to avoid the plug shaft 10h1 being separated from the clamp ring 10h3 and the socket 10h4 at the same time. Because simultaneous separation will cause the middle connecting plate 10e to rotate freely.

[0043] Since the locking switching mechanism 10h is located inside the liquid collecting tank 5, the locking switching mechanism 10h cannot be electrically controlled, and even if it is designed as a waterproof structure, it is prone to corrosion due to microorganisms in the liquid collecting tank 5. Therefore, it is necessary to design a mechanical mechanism that can switch the connection with the external pulling mechanism 10f or the left half net 3a. For this purpose, Figure 8-10As shown, the linear displacer 11 includes a rotator 11a, a rotating shaft 11b, a clamping strip 11c, a resistance spring 11d, a fixed circular plate 11e and a limit resistance plate 11f. The limit resistance plate 11f is fixedly mounted on one end of the guide ring 10h2. The insertion shaft 10h1 is slidably connected with the limit resistance plate 11f. The fixed circular plate 11e is fixedly mounted on the insertion shaft 10h1. The resistance spring 11d is used to provide an elastic force for the insertion shaft 10h1 to move away from the limit resistance plate 11f. The resistance spring 11d is sleeved on the outer edge of the insertion shaft 10h1. One end of the resistance spring 11d is in resistance to the limit resistance plate 11f, and the other end of the resistance spring 11d is in resistance to the fixed circular plate 11e. The insertion shaft 10h1 inserted into the clamping ring 10h3 can be pulled out through the elastic force of the resistance spring 11d. The rotator 11a is fixedly mounted on the liquid collecting tank 5, and the rotating shaft 11b is fixedly connected to the rotating shaft of the rotator 11a. The end of the rotating shaft 11b passes through the insertion hole 10h4, that is, the rotating shaft 11b pushes out the slide bar 11h1 originally inserted into the insertion hole 10h4, and makes the insertion shaft 10h1 inserted into the retaining ring 10h3, so that the arc-shaped slide bar 10a and the arc-shaped slide rail 10b cannot slide against each other. When the end of the plug shaft 10h1 is fully inserted into the retaining ring 10h3, the tail of the slide bar 11h slides out of the guide groove 11j, and the card strip 11c is fixedly installed on the end of the rotating shaft 11b. The plug shaft 10h1 is provided with a card slot for the card strip 11c to be inserted into. When the end of the socket 10h4 contacts the end of the plug shaft 10h1, the card strip 11c is inserted into the card slot, and then the rotating shaft 11b is driven to rotate by the rotator 11a, so that the plug shaft 10h1 is driven to rotate, so that the slide bar 11h is rotated and separated from the position opposite to the guide groove 11j, thereby realizing the locking between the plug shaft 10h1 and the limit plate 11f. That is, by switching the connection between the external pulling mechanism 10f or the left half net 3a through a mechanical structure, the use of electric control is avoided, thereby ensuring the long-term use of the equipment.

[0044] It should be noted that after locking, the electric push rod 10f1 is required to push the arc slide rail 10d to reset, and the target position when the left half net 3a and the right half net 3b are in a separated state is the position where the arc slide rail 10d is coaxial with the filter 3, so as to avoid collision between the plug shaft 10h1 and the rotating shaft 11b during rotation.

[0045] In order to realize that the rotary drive mechanism 1 can drive the auger 4 and the filter screen 3 to rotate at different speeds, for this purpose, Fig.11As shown, the primary transmission device 1a includes a large pulley 1a1 and a small pulley 1a2, the large pulley 1a1 and the small pulley 1a2 are connected by belt transmission, and the large pulley 1a1 is fixedly connected to the filter mounting seat 9, so that when the large pulley 1a1 is rotated, the filter 3 can be driven to rotate through the filter mounting seat 9, and the secondary transmission device 1b includes a small pulley 1b1 and a large pulley 1b2, the small pulley 1b1 and the large pulley 1b2 are connected by belt transmission, and the small pulley 1b1 is fixedly connected to the auger 4, so that when the small pulley 1b1 is rotated, the auger 4 can be driven to rotate, and the rotating motor 1c is fixedly installed on the outer shell of the liquid collecting tank 5, and the small pulley 1a2 and the large pulley 1b2 are both fixedly connected to the output end of the rotating motor 1c. By rotating the large pulley 2 1b2 and the small pulley 1 1a2 through the rotating motor 1c, the auger 4 and the filter mounting seat 9 can be rotated. Since the pulley ratios of the primary transmission 1a and the secondary transmission 1b are different, the rotation speed of the auger 4 can be faster than that of the filter 3.

[0046] like Fig.12 As shown, the spray mechanism 2 includes two connecting hard pipes 2a, which are located on both sides of the filter screen 3, and each connecting hard pipe 2a is fixedly provided with a plurality of nozzles 2b, and the water inlet of each connecting hard pipe 2a is connected to a water supply source. When water flows along the connecting hard pipe 2a and finally sprays out from the nozzle 2b, the sprayed water ray 2c can clean the filter screen 3.

[0047] like Fig.11 As shown, in order to make the water flow better to clean the garbage, and in order for the auger 4 to break up the fibers in the garbage during the pushing process, for this purpose, as shown in FIG. Fig.13 As shown, the spiral blade of the auger 4 is provided with a plurality of mounting holes, which are evenly distributed along the rotation direction of the spiral blade, and a plug 4c is installed in each mounting hole. By providing the plug 4c, the water flow can pass through better to improve the cleaning effect of the garbage, and the plug 4c can better shred the fiber. It needs to be explained that Figure 2 The cross-sectional view and Fig.13 Most of the plug posts 4c are hidden in order to better observe the mounting holes, and feed ports 4a are provided at the locations where the mounting holes are located.

[0048] When in use, the food waste enters through the feed port 4a and is discharged through the discharge port 4b to between the filter screen 3 and the auger 4. The auger 4 and the filter screen 3 are then driven to rotate by the rotary drive mechanism 1, so that the food waste is pushed out through the slag discharge port 7a by the auger 4. In the process of the waste being squeezed out, the spray mechanism 2 continuously sprays water toward the filter screen 3 to clean the waste.

[0049] In the above process, the left half net 3a and the right half net 3b are in a closed state. When the residual garbage inside the filter 3 needs to be cleaned, the left half net 3a and the right half net 3b are separated by the separation mechanism 10, so that the garbage in the flushing process can flow out along the gap between the left half net 3a and the right half net 3b. When the left half net 3a and the right half net 3b are in a closed state, the filter 3 drives the arc-shaped slide bar 10a to rotate along the arc-shaped slide rail 10b. When the left half net 3a and the right half net 3b are in a separated state, the filter 3 drives the arc-shaped slide bar 2 10c to rotate along the arc-shaped slide rail 2 10d.

[0050] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
