DETAILED DESCRIPTION

[0014] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and do not limit the present invention.

[0015] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0016] See also Figure 1 , an embodiment of the present invention provides a solid-liquid separation device for catering wastewater, the solid-liquid separation device for catering wastewater comprising:

[0017] A separation box 1 and a support leg 2, wherein a positioning groove is provided on the inner wall of the separation box 1, a sealing port and a coordination groove are provided at the bottom of the separation box 1, and an installation groove is provided on the side of the coordination groove provided in the separation box 1; an inlet pipe 3, which is connected to one end of the separation box 1 and is used to introduce catering wastewater into the separation box 1, and a first valve 4 is installed on the inlet pipe 3; a separation mechanism 5, which is installed on the separation box 1 and can be disassembled by the sealing port, and is used to separate solid and liquid from catering wastewater, and a valve for separating the separation mechanism is installed at the installation groove provided in the separation box 1. The locking mechanism 6 of the separation box 1 is fixed by the mechanism 5; the collecting cylinder 7 is fixedly mounted at the lower end of the separation box 1, and is used for collecting the separated catering waste residues. The lower end of the collecting cylinder 7 is open, and a sealing plug 8 is threadedly connected to the opening of the lower end of the collecting cylinder 7; the pushing mechanism 9 is mounted on the separation box 1, and is used for pushing out the waste residues in the collecting cylinder 7 and cleaning the separation mechanism 5; the water outlet pipe 10 is connected to the other end of the separation box 1, and is used for draining the catering waste water from the separation box 1. The water outlet pipe 10 is provided with a second valve 11.

[0018] When using the catering wastewater solid-liquid separation device, first connect the wastewater pipe and the water inlet pipe 3, open the first valve 4, and the wastewater can flow into the separation box 1 from the water inlet pipe 3. Under the obstruction of the separation mechanism 5, the waste residue is introduced into the collecting cylinder 7 for collection, and after the water fills the collecting cylinder 7, it is discharged through the water inlet and outlet pipes 10 of the separation mechanism 5. As the waste residue in the collecting cylinder 7 increases, the water in the collecting cylinder 7 decreases. If the waste residue needs to be discharged, the water inlet pipe 3 is closed through the first valve 4, the sealing plug 8 is rotated and taken out, and the ejection mechanism 9 is opened. The power output end of the ejection mechanism 9 can move downward to discharge the waste residue collected in the collecting cylinder 7. At the same time, the ejection mechanism 9 can scrape off the waste residue attached to the separation mechanism 5, thereby extending the service life of the separation mechanism 5. If the separation mechanism 5 needs to be replaced, pull the locking mechanism 6. After the locking mechanism 6 is separated from the separation mechanism 5, the separation mechanism 5 can be taken out from the sealing port and replaced.

[0019] like Figure 1 and Figure 2 As shown, as a preferred embodiment of the present invention, the separation mechanism 5 includes: a sealing block 51, which is arranged in cooperation with the sealing port opened by the separation box 1, and is used to control the opening and closing of the sealing port. A coordination block 52 is fixedly arranged on one side of the sealing block 51, and the coordination block 52 and the coordination groove are arranged in cooperation. The coordination block 52 has a locking port, and the locking mechanism 6 can be inserted into the locking port to fix the coordination block 52 in the coordination groove. A handle 53 is fixedly arranged on the coordination block 52; a groove body 54, which is fixedly connected to the other side of the sealing block 51, and the groove body 54 has a through hole for the passage of wastewater. A filter plate 55 for solid-liquid separation of wastewater is arranged on the groove body 54, and a positioning rod 56 is fixedly connected to the end of the groove body 54 away from the sealing block 51, and the positioning rod 56 can be inserted into the positioning groove.

[0020] like Figure 2 As shown, as a preferred embodiment of the present invention, the locking mechanism 6 includes: a guide rod 61, which is fixedly installed in the installation groove opened by the separation box 1, and a guide sleeve 62 is provided on the guide rod 61, and a locking block 63 is fixedly provided on the guide sleeve 62, and the locking block 63 and the locking mouth are matched with each other; a push spring 64, whose two ends are respectively fixedly connected to the inner wall of the installation groove and the guide sleeve 62, and is used to push the locking block 63 to be inserted into the locking mouth opened by the coordination block 52; a pull handle 65, which is fixedly connected to the guide sleeve 62, and is used to pull the locking block 63 out of the locking mouth opened by the coordination block 52.

[0021] When waste water flows through the filter plate 55, the filter plate 55 can block the waste residue, so that most of the waste residue falls into the collecting tube 7 for collection, and a small amount of waste residue adheres to the filter plate 55, while the water flows out through the through hole opened in the tank body 54. If the filter plate 55 is to be replaced, the pull handle 65 is pulled, and the pull handle 65 drives the guide sleeve 62 and the locking block 63 to slide along the guide rod 61 and compress the push spring 64, so that the locking block 63 can be separated from the locking mouth opened by the coordination block 52. At this time, the handle 53 is pulled, and the handle 53 can drive the coordination block 52, the sealing block 51 and the tank body 54 to move outward, so that the filter plate 55 can be taken out and replaced. After the replacement is completed, the tank body 54 is inserted from the sealing mouth until the positioning rod 56 is inserted into the positioning groove. At this time, the sealing block 51 can seal the sealing mouth, and the push spring 64 can push the locking block 63 into the locking mouth opened by the coordination block 52, thereby completing the installation of the tank body 54.

[0022] like Figure 1 As shown, as a preferred embodiment of the present invention, the ejection mechanism 9 includes: a protective cover 91, which is fixedly mounted on the top of the separation box 1, a power piece 92 is fixedly mounted in the protective cover 91, and an incomplete bevel gear 93 is fixedly connected to the output shaft of the power piece 92; a threaded column 94, whose two ends are respectively rotatably connected to the top of the separation box 1 and the inner wall of the protective cover 91, and a driven bevel gear 95 is fixedly arranged on one side of the threaded column 94, and two driven bevel gears 95 are provided and intermittently meshed with the incomplete bevel gear 93; a guide column 96, whose two ends are They are respectively fixedly connected to the inner wall of the protective cover 91 and the top of the separation box 1, a reciprocating plate 97 is sleeved on the guide column 96 and is threadedly connected to the threaded column 94, an extension rod 98 is fixedly arranged on the reciprocating plate 97, and one end of the extension rod 98 away from the reciprocating plate 97 is arranged in the separation box 1 and is fixedly connected to an ejection column 99, which can be inserted into the collection barrel 7 to push out the waste residue in the collection barrel 7; a cleaning plate 910, which is fixed on the upper side of the ejection column 99 and in sliding contact with the filter plate 55, is used to scrape off the waste residue attached to the surface of the filter plate 55.

[0023] When the waste residue in the collecting barrel 7 is pushed out, the power member 92 is turned on. The power member 92 is specifically a motor. The output shaft of the power member 92 drives the incomplete bevel gear 93 to rotate. Since the incomplete bevel gear 93 and the driven bevel gears 95 on both sides are intermittently meshed, the incomplete bevel gear 93 can drive the threaded column 94 to rotate forward and reversely through the driven bevel gear 95. The rotation of the threaded column 94 can make the reciprocating plate 97 drive the extension rod 98 and the pushing column 99 to reciprocate up and down along the guide column 96, so that the waste residue in the collecting barrel 7 can be pushed out. At the same time, the cleaning plate 910 can push out the waste residue attached to the filter plate 55, thereby extending the service life of the filter plate 55.

[0024] like Figure 1As shown, as a preferred embodiment of the present invention, it also includes: a guide plate 12, which is fixedly installed in the separation box 1 and is used to guide the waste residue into the collection cylinder 7 for collection.

[0025] By providing the guide plate 12 , it is ensured that all waste residues can be introduced into the collecting barrel 7 for collection, thereby preventing the waste residues from remaining in the separation box 1 .

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
