Description

Technical Field

[0001] The invention belongs to the technical field of separation equipment, and in particular relates to separation equipment and a method for digesting kitchen waste using the equipment. Background Art

[0002] Kitchen waste includes restaurant kitchen waste, household kitchen waste and other kitchen waste. Common ways to deal with kitchen waste include incineration. Incineration of the waste makes it incinerate and digest. However, if the kitchen waste is directly incinerated, because it contains a lot of water, it will not only reduce the temperature of the incinerator and affect the digestion effect of the waste, but also reduce the service life of the equipment. Generally, the waste materials are crushed first, and then the waste residues are dried and dehydrated by a centrifuge to achieve solid-liquid separation before incineration and digestion. In existing vertical centrifuges, a porous inner cylinder is usually used, and then a filter bag or filter cloth is arranged on the inside of the inner cylinder. The inner cylinder is driven by a motor to rotate at a high speed to achieve solid-liquid separation of the residue. However, due to the solid matter in the residue, a large amount of it will adhere to the filter cloth under the action of centrifugal force, which is easy to cause the filter cloth to be blocked, greatly reducing the solid-liquid separation ability of the filter cloth, affecting the effect of solid-liquid separation, and then affecting the efficiency of subsequent garbage incineration and digestion.

[0003] To this end, the Chinese invention patent with patent number CN202311277000.1 discloses a kitchen waste solid-liquid separation device, including a base, a shell and multiple separation devices, the separation device including a separation net, a filter bag, a crankshaft and a telescopic rod, the filter bag is located on the side of the separation net close to the central axis of the shell, a discharge port is provided at the bottom of the filter bag, and the crankshaft is tilted, so that when the telescopic rod is extended or retracted, it can drive the filter bag on the side of the discharge port to move synchronously; the invention sets a separation device to make the residue on the filter bag fall off during the extension and retraction of the telescopic rod to prevent the filter bag from being blocked, thereby achieving the effect of cleaning the filter bag, and synchronously turning over the residue attached to the filter bag, so that the moisture in the residue can be separated more thoroughly, thereby improving the separation effect of the filter bag on the residue.

[0004] However, in the above scheme, only the filter bag can be treated to prevent blocking, while the separation net cannot be treated to prevent blocking synchronously. During the synchronous operation of the separation net and the filter bag, the powdery slag, dust or water mixture thrown out from the garbage residue will inevitably adhere to the separation net, which may easily cause blocking to the separation net, thus affecting the separation effect and then the efficiency of incineration.

[0005] Moreover, when taking out the separated and dried garbage residue, the shell, separation net and filter bag need to be disassembled separately before the residue can be poured out, and then they need to be installed in sequence before the next round of work can be carried out, which takes a long time and thus affects work efficiency.

Then put the plastic discharge pipe back to its original position and close the transparent observation door to start the next round of work.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0066] refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 8 As shown, both ends of the outer wall of the push-sweeper ring 3 are fixedly connected with guide blocks 303, a screw rod 301 is connected between the support plate 101 and one end of the workbench 1 through a bearing, and a guide rod 302 is fixedly connected between the support plate 101 and the other end of the workbench 1, one guide block 303 is threadedly sleeved on the screw rod 301, and the other guide block 303 is slidably sleeved on the guide rod 302, a stepper motor 103 is fixedly installed on the top of the support plate 101, and the output end of the stepper motor 103 is fixedly connected to the upper end of the screw rod 301, and a brush strip 304 is fixedly connected to the inner wall of the push-sweeper ring 3 by bolts.

[0067] The above scheme is adopted: starting the stepper motor 103 drives the screw rod 301 to rotate, which can drive the guide block 303 to slide up and down along the guide rod 302, and then drive the push-sweep ring 3 to move up and down along the separation net 4, and then use the brush bar 304 to sweep the separation net 4 up and down, and then it is convenient to sweep the residue attached to the separation net 4 to make it detached, thereby further enhancing the anti-blocking efficiency.

[0068] The kitchen waste digestion method of the separation device comprises the following steps:

[0069] Collect kitchen waste, screen, sort and crush it;

[0070] Separate the crushed kitchen waste into solid and liquid;

[0071] The solid part is fed into the slurrying equipment, where high temperature and enzymatic hydrolysis technology are used to accelerate decomposition;

[0072] Wherein, the solid-liquid separation uses the separation equipment and includes the following steps:

[0073] S1. Open the end cover on the support plate 101, and the garbage residue enters from the feed port 601 and enters the corresponding filter bag 7 from the discharge port 602. The rotating motor 102 is started, and the separation net 4 is driven to rotate through the main gear 501, the gear column 407 and the inner gear ring 402. The residue will rotate under the drive of the separation net 4, the filter bag 7 and the shaking rod 6, and the residual water inside will be thrown out under the action of centrifugal force, and flow into the housing 2 and be discharged through the drain pipe to achieve solid-liquid separation;

[0074] S2. At the same time, the first bevel gear 502, the second bevel gear 607, and the second support rod 604 drive the cam 605 to rotate, so that the arc-shaped protrusion 606 rotates to abut against the arc block 608, and drives the rubber pleated sheet 603 to elastically expand and contract, thereby driving the shaking rod 6 to move up and down, and then driving the filter bag 7 to shake up and down, so that the residue attached to the filter bag 7 can be separated;

[0075] S3, and start the stepper motor 103, and drive the push-sweep ring 3 to move up and down through the screw rod 301, the guide rod 302, and the guide block 303, that is, drive the brush bar 304 to move up and down along the separation net 4, and when the separation net 4 rotates, the separation net 4 is synchronously swept in the axial and radial directions, so as to facilitate the separation of the residue attached to the separation net 4;

[0076] S4. When discharging, the filter bag 7 drives the plastic discharge pipe 703 to rotate to the position of the transparent observation door 201, the rotating motor 102 and the stepping motor 103 are turned off, the transparent observation door 201 is opened, and the plastic discharge pipe 703 is pulled to the outside of the shell 2, that is, the plastic discharge pipe 703 is pulled at the accommodating hole 408 to drive the block 704 to separate from the separation net 4, so that the discharge operation of the filter bag 7 can be realized, and then the plastic discharge pipe 703 is put back to its original position and the transparent observation door 201 is closed, and the next round of work can be carried out.

[0077] On the basis of Example 1, the following settings are also performed:

[0078] See also Fig. 9The outer wall of the transparent observation door 201 is fixedly connected with a vertical plate 8 by bolts, the end of the vertical plate 8 is fixedly connected with a telescopic cylinder 801 by bolts, the output end of the telescopic cylinder 801 is connected to the base of the first motor 802 by bolts, the output end of the first motor 802 is fixedly connected with a feeding screw 803, and the shaking rod 6 is provided with an accommodating channel 804, and the accommodating channel 804 is arranged corresponding to the feeding screw 803 and the plastic discharge pipe 703;

[0079] Through this arrangement, when discharging, the first motor 802 and the telescopic cylinder 801 are started, and the feeding screw 803 rotates and extends into the plastic discharge pipe 703 and the shaking rod 6. On the one hand, it is convenient to transport the garbage residue in the filter bag 7 out more quickly. On the other hand, the feeding screw 803 can extend into the shaking rod 6, which is convenient for more thorough discharge of the residual material in the shaking rod 6, thereby helping to further improve the discharge efficiency and thereby improve the work efficiency.

[0080] Working principle of the present invention:

[0081] When in use, open the end cover and transparent observation door 201 on the support plate 101, and the filter bag 7 is fixedly installed on the shaking rod 6 through the positioning cylinder 705. First, place the shaking rod 6 and the filter bag 7 in the separation net 4. At this time, the plastic positioning ring 701 moves along the slide bar 405 until the positioning block 702 is inserted into the corresponding positioning groove 406, which is convenient for the stable installation of the filter bag 7 and the separation net 4, and then extends into the accommodating hole 408 to pull the plastic discharge pipe 703 onto the separation net 4. At this time, the block 704 abuts against the wall of the separation net 4, and then close the transparent observation door. The residue enters from the feed port 601 and enters the corresponding filter bag 7 from the discharge port 602. The rotary motor 102 is started, and the separation net 4 is driven to rotate through the main gear 501, the tooth column 407 and the inner gear ring 402. The residue will rotate under the drive of the separation net 4, the filter bag 7 and the shaking rod 6, and the residual water inside is thrown out under the action of centrifugal force to achieve solid-liquid separation; the cam 605 is driven to rotate through the first bevel gear 502, the second bevel gear 607 and the second support rod 604, that is, the arc-shaped protrusion 606 rotates. The arc block 608 is pressed against and the rubber pleated sheet 603 is elastically extended, so that the shaking rod 6 is extended and moved up and down, and then the filter bag 7 is shaken up and down, so that the residue attached to the filter bag 7 is separated, which is beneficial to improve the anti-blocking efficiency; at the same time, the stepping motor 103 is started, and the push-sweep ring 3 is driven to move up and down through the screw rod 301, the guide rod 302, and the guide block 303, that is, the brush strip 304 is driven to move up and down along the separation net 4, and when the separation net 4 rotates, the axial direction of the separation net 4 is adjusted. It is swept synchronously in the radial direction to facilitate the separation of residues attached to the separation net 4, further improving the anti-blocking efficiency; the plastic discharge pipe 703 is easy to take on the separation net 4 through the block 704 and the accommodating hole 408. When discharge is required, the transparent observation door 201 is opened to pull the plastic discharge pipe 703 to the outside of the shell 2 to realize the discharge operation of the filter bag 7, and then the plastic discharge pipe 703 is put back in place and the transparent observation door 201 is closed to carry out the next wheel work, saving time and effort; thereby helping to improve the separation work efficiency.
