Description

Technical Field

[0001] The utility model relates to the technical field of solid-liquid separation of garbage, and more specifically to a solid-liquid separation system for garbage used in sanitation. Background Art

[0002] A large amount of various types of garbage will be generated in sanitation work, and these garbage are usually divided into solid garbage and liquid garbage. In order to facilitate the recycling of garbage, it is usually necessary to separate the solid and liquid. At this time, a garbage solid-liquid separation system, that is, a garbage solid-liquid separator, is needed.

[0003] Existing garbage solid-liquid separators usually use a drum to drive the garbage to rotate centrifugally, so that the liquid garbage is centrifugally thrown out from the through-holes of the drum, thereby achieving the solid-liquid separation effect of the garbage. However, in this process, some small particles of solid garbage or viscous garbage can easily pile up in the through-holes of the drum and cause blockage, which will greatly affect the separation efficiency of the liquid garbage. In view of this, we propose a garbage solid-liquid separation system for sanitation use. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to actual needs, and provide a sanitation garbage solid-liquid separation system to solve the technical problem that the through holes in the drum of the current garbage solid-liquid separator are easily blocked by small particles of solid garbage or viscous garbage.

[0005] To solve the above technical problems, the present invention provides the following technical solutions: a solid-liquid separation system for sanitation garbage, comprising a bottom plate, a rectangular shell arranged on the top of the bottom plate via a bracket, a centrifugal drum rotatably arranged inside the rectangular shell, and both ends of the centrifugal drum extend to the outside of the rectangular shell, a surface of the centrifugal drum located inside the rectangular shell is equidistantly provided with a plurality of through holes, an inner wall of the centrifugal drum is provided with spiral guide blades, a feeding structure is provided at one end of the centrifugal drum, a driving structure is provided on the side of the rectangular shell facing away from the feeding structure, an intermittent jet structure is provided on the top of the rectangular shell, and a high-pressure fan is provided on the top of the rectangular shell;

[0006] A plurality of groups of spiral jet structures are equidistantly arranged on the intermittent jet structure.

[0007] The utility model is designed with a high-pressure fan and an intermittent jet structure. Therefore, during the rotation of the centrifugal drum, high-pressure gas can be delivered to the intermittent jet structure through the high-pressure fan, and then the jet head in the intermittent jet structure performs intermittent gas jets in cooperation with the solenoid valve. Therefore, when the through hole of the centrifugal drum rotates to under the jet head, the high-pressure gas ejected by the jet head will impact the through hole, thereby completing the cleaning of the through hole, avoiding the blockage of the through hole by small particles of solid garbage or viscous garbage, and ensuring the centrifugal separation effect of the centrifugal drum on liquid garbage; the utility model is also designed with a spiral jet structure, and the spiral jet structure is rotatably arranged under the jet head, so when the through hole of the centrifugal drum rotates to under the jet head, the high-pressure gas ejected by the jet head will impact the through hole, thereby completing the cleaning of the through hole, avoiding the blockage of the through hole by small particles of solid garbage or viscous garbage, and ensuring the centrifugal separation effect of the centrifugal drum on liquid garbage. When the body is in the air, the gas enters the docking cover of the spiral injection structure and then separates. A part of the gas is vertically injected through the vertical nozzle, and the other part of the gas is spirally injected downward through the spiral nozzle. At this time, the ejected spiral gas will drive the spiral injection structure to rotate automatically, and the vertical injection and spiral downward injection can have a better impact cleaning effect on the through hole, and can avoid the situation that some small particles of garbage stuck in the through hole cannot be ejected. The airflow injected in the spiral downward can clean the inner wall of the through hole more thoroughly, and avoid scaling caused by incomplete cleaning of the inner wall of the through hole for a long time, thereby shrinking the through hole. Therefore, with the cooperation of the spiral injection structure, the effect of cleaning the through hole is further guaranteed.

[0008] Preferably, the inner bottom of the rectangular shell is funnel-shaped, and a liquid outlet is arranged at the center of the bottom of the rectangular shell.

[0009] Preferably, the feeding structure includes a mounting cover, a hopper and a fixed frame, the mounting cover is rotatably connected to one port of the centrifugal drum, the bottom inner bottom of the mounting cover is inclined, the fixed frame is arranged at the bottom of the mounting cover, the fixed frame is connected to the bottom plate, the hopper is arranged at the top of the mounting cover, and the hopper is communicated with the mounting cover.

[0011] Preferably, the intermittent jet structure includes a mounting tube, mounting seats are arranged at both ends of the mounting tube, the mounting seats are connected to the rectangular shell, a tee is connected to the mounting tube, and the input end of the tee is connected to the output end of the high-pressure blower, the bottom of the mounting tube is arranged at a jet head corresponding to the through hole, and an electromagnetic valve is arranged on the jet head.

[0012] Preferably, the spiral jet structure includes a docking cover, which is rotatably arranged at the bottom of the jet head.

A fixed rod is connected between the spiral nozzle and the vertical nozzle.

[0013] Preferably, the vertical nozzles are arranged symmetrically with respect to the axis of the through hole, and the diameter of the circle formed by the spiral nozzles is smaller than the diameter of the through hole.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model is designed with a high-pressure fan and an intermittent jet structure. Therefore, during the rotation of the centrifugal drum, high-pressure gas can be delivered to the intermittent jet structure through the high-pressure fan, and then the jet head in the intermittent jet structure performs intermittent gas jetting under the cooperation of the solenoid valve. Therefore, when the through hole of the centrifugal drum rotates under the jet head, the high-pressure gas ejected by the jet head will impact the through hole, thereby completing the cleaning of the through hole, avoiding the blockage of the through hole by small particles of solid waste or viscous waste, ensuring the centrifugal separation effect of the centrifugal drum on liquid waste, and solving the technical problem that the through holes in the current solid-liquid separator drum are easily blocked by small particles of solid waste or viscous waste. Therefore, the utility model has the advantage of more stable solid-liquid waste separation effect.

[0016] 2. The present invention also adopts a designed spiral injection structure, which is rotatably arranged under the nozzle. Therefore, when the nozzle ejects gas, the gas enters the docking cover of the spiral injection structure and then separates. Part of the gas is vertically injected through the vertical nozzle, and the other part of the gas is spirally injected downward through the spiral nozzle. At this time, the ejected spiral gas will drive the spiral injection structure to rotate automatically, and the vertical injection and spiral downward injection can have a better impact cleaning effect on the through-hole, which can avoid the situation that some small particles of garbage stuck in the through-hole cannot be ejected, and the airflow injected in the spiral downward can clean the inner wall of the through-hole more thoroughly, avoiding the situation that the inner wall of the through-hole is not thoroughly cleaned for a long time and causes scaling, thereby causing the through-hole to shrink. Therefore, with the cooperation of the spiral injection structure, the effect of cleaning the through-hole is further guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figures 1 to 4As shown, the utility model relates to a solid-liquid separation system for sanitation garbage, comprising a bottom plate 1, a rectangular shell 3 is arranged on the top of the bottom plate 1 through a bracket 2, a centrifugal drum 4 is rotatably arranged inside the rectangular shell 3, and both ends of the centrifugal drum 4 extend to the outside of the rectangular shell 3, a surface of the centrifugal drum 4 inside the rectangular shell 3 is equidistantly provided with a plurality of through holes 402, an inner wall of the centrifugal drum 4 is arranged with spiral guide blades 401, a feeding structure 5 is arranged at one end of the centrifugal drum 4, and a driving mechanism is arranged on the side of the rectangular shell 3 facing away from the feeding structure 5.

The mounting seat 804 is connected to the rectangular shell 3, and a three-way pipe is connected to the mounting pipe 801, and the input end of the three-way pipe is connected to the output end of the high-pressure fan 7. The bottom of the mounting pipe 801 is arranged at a jet head 802 corresponding to the through hole 402, and the jet head 802 is arranged with a solenoid valve 803; when the solid-liquid separation of garbage is carried out , directly add the garbage into the centrifugal drum 4 through the feeding structure 5, and then control the driving structure 6 to drive the centrifugal drum 4 to rotate. During the rotation of the centrifugal drum 4, centrifugal force is applied to the garbage, and the spiral guide blades 401 inside the centrifugal drum 4 will drive the garbage to the other end. During this process, the liquid garbage will be directly thrown out from the through hole 402 under the action of centrifugal force, and then fall into the interior of the rectangular shell 3. The solid garbage is discharged from the other end of the centrifugal drum 4, thereby realizing the solid-liquid separation of the garbage. During the rotation of the centrifugal drum 4, high-pressure gas can be delivered to the mounting pipe 801 of the intermittent jet structure 8 through the high-pressure fan 7, and then the jet head 802 performs intermittent gas injection in cooperation with the solenoid valve 803. Therefore, when the through hole 402 of the centrifugal drum 4 rotates to the bottom of the jet head 802, the high-pressure gas ejected by the jet head 802 will impact the through hole 402, thereby completing the cleaning of the through hole 402, avoiding the blockage of the through hole 402 by small particles of solid garbage or viscous garbage, and ensuring the centrifugal separation effect of the centrifugal drum 4 on liquid garbage.

[0024] Specifically, the bottom of the rectangular shell 3 is funnel-shaped, and a liquid outlet 301 is arranged at the center of the bottom of the rectangular shell 3. The liquid waste entering the rectangular shell 3 is collected in the funnel shape and then discharged from the liquid outlet 301.

The bottom of the mounting cover 501 is inclined. The fixing frame 503 is arranged at the bottom of the mounting cover 501. The fixing frame 503 is connected to the bottom plate 1. The hopper 502 is arranged at the top of the mounting cover 501, and the hopper 502 is connected to the mounting cover 501. The garbage is added to the hopper 502, and then the garbage enters the mounting cover 501, and then slides into the centrifugal drum 4 along the inner inclined surface of the mounting cover 501. The fixing frame 503 is used to limit and fix the mounting cover 501 to prevent the mounting cover 501 from rotating with the centrifugal drum 4.

[0026] Furthermore, the drive structure 6 includes a motor 601, a first gear plate 602 and a second gear plate 603.

The motor 601 drives the first gear plate 602 to rotate, and the first gear plate 602 drives the centrifugal drum 4 to rotate through the second gear plate 603.

[0027] In an embodiment of the present invention, a plurality of spiral jet structures 9 are equidistantly arranged on the intermittent jet structure 8; the spiral jet structure 9 includes a docking cover 901, which is rotatably arranged at the bottom of the jet head 802, a vertical nozzle 903 is arranged in the center of the bottom of the docking cover 901, and a plurality of spiral nozzles 902 are equidistantly arranged around the bottom of the docking cover 901, and a fixing rod 904 is connected between the spiral nozzle 902 and the vertical nozzle 903; the vertical nozzle 903 is symmetrically arranged about the axis of the through hole 402, and the diameter of the circle formed by the spiral nozzle 902 is smaller than the diameter of the through hole 402; when the jet head 802 ejects gas, the gas enters the docking cover 901 of the spiral jet structure 9, and then separates, and a part of the gas is discharged. The body is vertically ejected through the vertical nozzle 903, and another part of the gas is spirally ejected downward through the spiral nozzle 902. At this time, the ejected spiral gas will drive the spiral injection structure 9 to rotate. With the cooperation of the vertical injection and the spiral downward injection airflow, the impact cleaning effect on the through hole 402 can be better, and it can avoid the situation where some small particles of garbage stuck in the through hole 402 cannot be ejected. In addition, the spiral downward injection airflow can clean the inner wall of the through hole 402 more thoroughly, and avoid the scaling caused by the incomplete cleaning of the inner wall of the through hole 402 for a long time, thereby shrinking the through hole 402. Therefore, with the cooperation of the spiral injection structure 9, the cleaning effect of the through hole 402 is further guaranteed.

[0028] Working principle: This embodiment provides a solid-liquid separation system for sanitation garbage. First, when performing solid-liquid separation on garbage, the garbage is directly added to the centrifugal drum 4 through the feeding structure 5, and then the driving structure 6 is controlled to drive the centrifugal drum 4 to rotate. During the rotation of the centrifugal drum 4, centrifugal force is applied to the garbage, and the spiral guide blades 401 inside the centrifugal drum 4 will drive the garbage to the other end. In this process, the liquid garbage will be directly thrown out from the through hole 402 under the action of centrifugal force, and then fall into the inside of the rectangular shell 3, and the solid garbage will be discharged from the other port of the centrifugal drum 4, thereby achieving solid separation of the garbage. Liquid separation: During the rotation of the centrifugal drum 4, high-pressure gas can be delivered to the installation pipe 801 of the intermittent jet structure 8 through the high-pressure blower 7, and then the jet head 802 performs intermittent gas jetting in cooperation with the solenoid valve 803. Therefore, when the through hole 402 of the centrifugal drum 4 rotates to the bottom of the jet head 802, the high-pressure gas ejected by the jet head 802 will impact the through hole 402, thereby completing the cleaning of the through hole 402, avoiding the blockage of the through hole 402 by small particles of solid waste or viscous waste, and ensuring the centrifugal separation effect of the centrifugal drum 4 on liquid waste;

[0029] Secondly, when the nozzle 802 sprays gas, the gas enters the docking cover 901 of the spiral injection structure 9 and then separates. Part of the gas is vertically injected through the vertical nozzle 903, and the other part of the gas is spirally injected downward through the spiral nozzle 902. At this time, the spiral gas injected will drive the spiral injection structure 9 to rotate. With the cooperation of the vertical injection and the spiral downward injection airflow, the impact cleaning effect of the through hole 402 can be better, and it can avoid the situation where some small particles of garbage stuck in the through hole 402 cannot be ejected. In addition, the spiral downward injection airflow can clean the inner wall of the through hole 402 more thoroughly, and avoid the inner wall of the through hole 402 from being not thoroughly cleaned for a long time, causing scaling, thereby shrinking the through hole 402. Therefore, with the cooperation of the spiral injection structure 9, the cleaning effect of the through hole 402 is further guaranteed.
