DETAILED DESCRIPTION

[0030] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 、 Figure 2 The utility model provides an embodiment of a solid waste and waste liquid pre-separation device, comprising a shell 1, a liquid inlet pipe 2 for conveying solid waste liquid into the shell 1 is fixedly connected to the top of the shell 1, a stepper motor 3 is fixedly connected to the front of the shell 1, the stepper motor 3 can accurately control the rotation angle of its output shaft, conveniently adjust the rotation speed and rotation angle of its rotating shaft, and can be adjusted accordingly according to different needs to improve the control accuracy. A separation mechanism is provided inside the shell 1, and the separation mechanism includes a rotating shaft 4, and the number of rotating shafts 4 is set to two groups, one of which is fixedly connected to the front of the rotating shaft 4 and the rear side of the output shaft of the stepper motor 3, and the two groups of rotating shafts 4 are connected by a transmission belt 5. The stepper motor 3 provides power to drive the transmission belt 5 to move through the rotating shaft 4, and the surface of the transmission belt 5 is provided with a water permeable hole 6 for solid-liquid separation.

[0032] Reference Figure 1-Figure 2 The surface of the conveyor belt 5 is provided with an auxiliary mechanism, which includes a mounting frame 7, a mounting plate 8, a filter screen 9, a positioning rod 10, a spring 11, a positioning groove 12, and a sealing pad 13. The right part of the shell 1 is fixedly connected with a collection box 15 for collecting solid waste after solid separation, which is convenient for centralized processing. A collection mechanism is provided inside the collection box 15. The left part of the shell 1 is fixedly connected with a liquid outlet pipe 20 for discharging the liquid after solid-liquid separation inside the shell 1, and a valve is provided on the top of the liquid outlet pipe 20.

[0033] Reference Figure 3 The number of mounting brackets 7 is set to be multiple, and the mounting plate 8 is installed on the side where the multiple mounting brackets 7 are close to each other. The surfaces of the mounting plate 8 and the conveyor belt 5 are perpendicular to each other. By setting the mounting plate 8, the solid waste can be driven to move with the inclined conveyor belt 5, thereby preventing the solid waste from sliding to the inner bottom of the shell 1 due to too little friction, thereby ensuring the effect of solid-liquid separation. The filter screen 9 is set on the inner wall of the mounting plate 8, and the filter screen 9 allows liquid to pass through but not solid particles, thereby playing a screening effect. The positioning rod 10 is slidably installed on the inner wall of the mounting plate 8, and the positioning rod 10 is elastically connected to the inner wall of the mounting plate 8 by a spring 11. The spring 11 is provided so that the positioning rod 10 has an elastic force away from the center direction of the mounting plate 8. The positioning groove 12 is opened on the side where the multiple mounting brackets 7 are close to each other. The cooperation of the positioning rod 10 and the positioning groove 12 plays a positioning role, ensures the installation accuracy of the mounting plate 8, and improves the effect of solid-liquid separation.

[0034] Reference Figure 2 、 Figure 3The sealing pad 13 is fixedly installed at the bottom of the mounting plate 8. The surface of the sealing pad 13 contacts the surface of the conveyor belt 5. The positioning rod 10 and the positioning groove 12 cooperate to ensure that the mounting plate 8 is installed to the bottom of the mounting frame 7, so that the sealing pad 13 can fit on the surface of the conveyor belt 5 to ensure the sealing effect, which is beneficial to improve the solid-liquid separation effect. The mounting frame 7 and the mounting plate 8 are fixedly connected by fastening bolts 14, which is convenient for disassembly and installation. The mounting plate 8 with poor filtering effect of the filter screen 9 can be disassembled and replaced to further improve the solid-liquid separation effect.

[0035] Reference Figure 1 、 Figure 2 、 Figure 4 The collecting mechanism includes an electric cylinder 16, which is fixedly mounted on the back of the collecting box 15. A push rod 17 is fixedly connected to the front side of the output shaft of the electric cylinder 16. A pressing plate 18 is fixedly connected to the front side of the pushing rod 17 for squeezing the solid waste, which can reduce the water content and volume of the solid waste. The pressing plate 18 slides on the inner wall of the collecting box 15. The sliding direction of the pressing plate 18 is forward and backward. The bottom of the pressing plate 18 is set to an inclined surface. The bottom of the pressing plate 18 fits the bottom of the inner wall of the collecting box 15. The slope of the inclined surface of the bottom of the inner wall of the collecting box 15 is the same as the slope of the bottom inclined surface of the pressing plate 18, and the inclined surface is lower on the left and higher on the right, so that the liquid can flow freely to the left into the interior of the shell 1, thereby improving the effect of solid-liquid separation. A water permeable hole 2 19 is provided on the left side of the collecting box 15.

[0036] Working principle: When in use, waste liquid containing solid waste is transported to the inside of the shell 1 through the liquid inlet pipe 2, and the waste liquid falls on the top of the conveyor belt 5. Then the power supply of the stepper motor 3 is started, and the stepper motor 3 works to rotate the rotating shaft 4 and drive the conveyor belt 5 to move. When the conveyor belt 5 moves, it drives the mounting frame 7 and the mounting plate 8 on the surface of the conveyor belt 5 to move. The movement of the mounting plate 8 transports the solid waste inside the waste liquid above the conveyor belt 5 from the left bottom inside the shell 1 to the right top inside the shell 1. At the same time, the liquid in the waste liquid will not follow the movement of the solid waste, but will fall to the bottom of the shell 1 through the filter screen 9 and the water permeable hole 6 under the action of gravity, thereby improving the separation effect.

[0037] The solid waste that moves to the top right side of the housing 1 will eventually fall into the interior of the collection box 15 as the conveyor belt 5 moves. At this time, the power supply of the electric cylinder 16 is activated, and the electric cylinder 16 drives the push rod 17 to move forward. The displacement of the push rod 17 drives the pressure plate 18 to move. The displacement of the pressure plate 18 squeezes the solid waste inside the collection box 15, thereby reducing the volume of the solid waste and reducing the volume occupied by the solid waste. This increases the amount of solid waste that can be stored inside the collection box 15, reduces the frequency of cleaning the collection box 15, and improves work efficiency. At the same time, when the pressure plate 18 moves to squeeze the solid waste, it also squeezes out the water contained in the solid waste. After being squeezed out, the water flows into the interior of the housing 1 through the second water permeable hole 19, thereby reducing the water content in the solid waste, thereby further improving the effect of solid separation.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
