Description

Technical Field

[0001] The utility model relates to the technical field of kitchen waste treatment, in particular to an MPS dehydration system. Background Art

[0002] At present, with the growing national economy, people's quality of life is gradually improving, and table culture is becoming increasingly rich. Food waste generally refers to "leftovers, expired food, scraps, waste and other wastes generated in the process of processing and consuming food in restaurants, hotels, canteens of enterprises and institutions, and families." At this stage, my country's annual food waste production has reached more than 100 million tons. Failure to effectively handle these organic wastes will bring about a series of adverse consequences, such as environmental pollution and food safety problems.

[0003] The most common dehydration process on the market is mechanical pressing, which uses a press or similar equipment to squeeze out the water from the garbage through mechanical force, making it drier.

[0004] However, the mechanical pressing method still has some shortcomings in actual use: the limitations of a single pressing point in practical applications are becoming increasingly prominent, and its actual effect has failed to meet the expected standards, especially in the pressing and water filtration links. This shortcoming directly leads to a high moisture content in the material and incomplete water filtration, which not only increases the complexity and energy consumption of subsequent processing steps, but also seriously affects the efficiency and quality of material resource processing.

[0005] To this end, we designed the MPS dehydration system to solve the above problems. Utility Model Content

[0006] The purpose of the present invention is to provide an MPS dehydration system to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the MPS dehydration system provided by the utility model includes a frame, a material inlet is provided at the top of the frame, a sorting component is provided below the inside of the material inlet, including a servo motor provided on one side of the material inlet, a driving end of the servo motor is fixedly connected to a crushing roller, a cavity is provided at the bottom of the crushing roller, a pressing section is provided at the bottom of the cavity, a driving motor is provided on one side of the pressing section, a spiral feeding rod is provided in the pressing section, and the driving end of the driving motor is fixedly connected to the spiral feeding rod.

[0008] Furthermore, a water outlet is provided on a side of the pressing section away from the driving motor, a slag outlet is provided on one side of the water outlet, and the other end of the spiral feeding rod extends into the slag outlet.

[0009] Furthermore, the material inlet further includes a second pressing component and a third pressing component, wherein the second pressing component includes a second-level material inlet, and a second-level pressing section is provided at the bottom of the second-level material inlet.

[0010] Furthermore, a second spiral feeding rod is provided in the second-stage pressing section, a second-stage driving motor is provided at one end of the second spiral feeding rod, a pushing head is provided at the other end of the second-stage driving motor, a cylinder is fixedly provided at a section close to the pushing head, a second-stage slag discharge outlet is also provided on the outside of the pushing head, a second-stage water discharge outlet is provided at the bottom of the second-stage pressing section, and the bottom of the second-stage pressing section is also fixedly connected to the second-stage frame.

[0011] Furthermore, the third pressing assembly includes a third-stage material inlet, a third-stage pressing section is obliquely arranged at the bottom of the third-stage material inlet, and a third-stage frame is fixedly connected to the bottom of the third-stage pressing section.

[0012] Furthermore, a third spiral feeding rod is provided in the third-stage pressing section, and a third-stage driving motor is also provided on the side of the third-stage pressing section away from the third-stage material inlet. The driving end of the third-stage driving motor is fixedly connected to the third spiral feeding rod, and the other end of the third spiral feeding rod is rotatably connected to the inner wall of the third-stage pressing section. The bottom of the third-stage pressing section is respectively provided with a third-stage water discharge outlet and a third-stage material residue discharge outlet.

[0014] Compared with the existing technology, the beneficial effects of the present invention are as follows: unprocessed materials enter the first, second and third pressing components in sequence for multiple solid-liquid separations. Compared with the traditional dehydration mechanism, which uses a shaft to transport the material, the modified pressing screw not only retains the original material transportation function, but also adds efficient pressing and dehydration capabilities. This combination of dual functions enables the equipment to complete more tasks and greatly improves the flexibility and efficiency of the production line.

[0015] The materials processed by this MPS dehydration system have a significant feature compared to the single pressing system, that is, the pressing dehydration and reduction efficiency is high. The overall dehydration rate is ≥75%, and the volume reduction rate is ≥75%. After the systematic dehydration and reduction treatment, it provides a good foundation for subsequent resource processing. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] During specific implementation, the material first enters the sorting component through the material inlet 1, wherein the servo motor 7 of the sorting component drives the crushing roller 8 to crush and sort the material. The crushed and sorted material enters the pressing section 4, and the driving motor 5 drives the spiral feeding rod to screw-press and dehydrate the material. The material is transported forward along with the spiral blades in the pressing section 4. The central axis of the spiral end adopts a variable diameter shaft, and the shaft diameter is gradually increased.

The water or juice flows through the screen to the water receiving tray under the machine, and is collected and taken away through the pipeline. The separated solid slag is discharged from the slag discharge port 3.

[0029] It should be noted that the taper of the pressing section 4 can be adjusted. Under control, the dehydration rate of the first-stage pressing is 50%, and the moisture content of the material reaches 75%-78%.

[0030] See Figure 3-4 As shown, the material inlet 1 further includes a second pressing assembly and a third pressing assembly, wherein the second pressing assembly includes a second-stage material inlet 11, and a second-stage pressing section 41 is provided at the bottom of the second-stage material inlet 11.

[0031] A second spiral feeding rod is provided in the second-stage pressing section 41, and a second-stage driving motor 51 is provided at one end of the second spiral feeding rod. A pushing head is provided at the other end of the second-stage driving motor 51, and a cylinder 71 is fixedly provided at a section close to the pushing head.

A second-stage water discharge outlet 21 is provided at the bottom of the second-stage pressing section 41, and a second-stage frame 61 is also fixedly connected to the bottom of the second-stage pressing section 41.

[0032] During specific implementation, the material after the first-stage pressing process enters the second-stage material inlet 11 through the conveying equipment, wherein the second-stage drive motor 51 drives the second spiral feeding rod to mechanically dehydrate the material again, wherein the push head part of the second spiral feeding rod is controlled by the cylinder 71 to control its pressure, wherein the material in the second-stage pressing section 41 repeats the above steps and the remaining material after being squeezed by the second spiral feeding rod enters the third-stage pressing layer.

[0033] It should be noted that the best match between output and dryness / wetness can be achieved by adjusting the gap of the second-stage slag discharge outlet 31, and a dryness / wetness adjustment device can be provided at the tail end of the second feeding rod.

[0034] It should also be added that the push head pressure is controlled by the cylinder 71 so that the pressure is adjusted at 0.3-0.5 MPa, wherein the dehydration rate of the second-stage pressing section 41 is 50%, the moisture content of the material reaches 73%-75%, and the volume reduction rate reaches 70%.

[0035] See Figure 5-6 The third pressing assembly includes a third-stage material inlet 12, and a third-stage pressing section 42 is obliquely arranged at the bottom of the third-stage material inlet 12. The bottom of the third-stage pressing section 42 is fixedly connected to a third-stage frame 62.

[0036] A third spiral feeding rod is provided in the third-stage pressing section 42. A third-stage driving motor 52 is also provided on the side of the third-stage pressing section 42 away from the third-stage material inlet 12. The driving end of the third-stage driving motor 52 is fixedly connected to the third spiral feeding rod, and the other end of the third spiral feeding rod is rotatably connected to the inner wall of the third-stage pressing section 42. The bottom of the third-stage pressing section 42 is respectively provided with a third-stage water discharge outlet 22 and a third-stage slag discharge outlet 32.

[0037] Screens are provided between the water outlet 2, the second-stage water outlet 21 and the third-stage water outlet 22 and the pressing section 4, the second-stage pressing section 41 and the third-stage pressing section 42, and water receiving trays are provided at the bottom of the multiple screens.

[0038] During specific implementation, the material enters the third-stage material inlet 12, and the third spiral feeding rod in the third-stage pressing section 42 is driven by the third-stage drive motor 52 and rotates in the third-stage pressing section 42. The material is pressed for the third time in the third-stage pressing section 42, and the above steps are repeated again. According to the tilt setting of the third-stage frame 62, the liquid material will be discharged from the third-stage water discharge outlet 22, and the solid material will be discharged through the third-stage slag discharge outlet 32.

[0039] It should be noted that the closer the third threaded feeding rod is to the third-stage slag discharge outlet 32 , the larger its shaft diameter is, thereby achieving step-by-step squeezing and making the squeezing more thorough.

[0040] It should also be noted that the third stage pressing section 42 is controlled by the third spiral feeding rod, and the dehydration rate of the material is 40%, and the moisture content reaches 70%-72%.

The material is transported forward along with the spiral blades in the pressing section 4. The middle shaft at the end of the spiral adopts a variable diameter shaft, and the shaft diameter gradually increases. When the material is transported to the end, the space becomes narrower and narrower. When the material reaches the discharge port, it is squeezed and discharged. The water or juice flows through the screen to the water receiving tray under the machine, and then is collected through the pipeline. The separated solid residue is discharged from the residue discharge port 3;

[0042] The processed material enters the second-stage material inlet 11 through the conveying equipment, where the second-stage drive motor 51 drives the second screw feeder to mechanically dehydrate the material again. The pressure of the pusher part of the second screw feeder is controlled by the cylinder 71. The material in the second-stage pressing section 41 repeats the above steps and is squeezed by the second screw feeder. The remaining material enters the third-stage pressing layer;

[0043] The material enters the third-stage material inlet 12, where the third spiral feeding rod in the third-stage pressing section 42 is driven by the third-stage drive motor 52 and rotates in the third-stage pressing section 42.
