Description

Technical Field

[0001] This utility model relates to the field of extruder technology, and in particular to an extruder with a multi-stage extrusion mechanism. Background Technology

[0002] In many sectors of modern industrial production and resource management, such as food processing, environmental solid waste treatment, agricultural waste utilization, papermaking, and biomass energy, the dehydration of materials is of paramount importance. For example, in food processing, efficient dehydration is crucial for processing residues after fruit and vegetable juicing to reduce subsequent processing costs and extend shelf life. In environmental protection, insufficient dehydration of waste residues from urban sludge and industrial wastewater treatment not only increases transportation costs but also creates difficulties for subsequent landfill or incineration. In the biomass energy industry, the dryness of dehydrated raw materials such as crop straw and forestry waste directly affects their energy conversion efficiency and combustion stability.

[0003] Chinese Patent Publication No. CN 109353054 A discloses a desqueezing machine, including a frame, barrel, feed inlet, discharge outlet, dewatering hole, screw, and first drive mechanism. The screw includes a rod body, a first thread with first threads and a second thread with second threads sequentially wound around the rod body along the feeding direction. The first and second threads have the same helical direction and the diameters of the first and second threads are the same. A first feeding groove is formed between every two adjacent first threads, and a second feeding groove is formed between every two adjacent second threads. The depth of the first feeding groove is greater than the depth of the second feeding groove. This desqueezing machine, by providing a first and second feeding groove on the screw body, and with the first feeding groove having a greater depth than the second feeding groove, allows the second feeding groove to further compress the material within a limited space in order to cooperate with the first feeding groove in conveying the same amount of material, greatly improving the desqueezing and dewatering effect.

[0004] The existing technical solutions mentioned above have the following shortcomings: the extrusion devices in this technology are mostly only suitable for smaller material blocks, which affects work efficiency and has certain limitations. There is room for optimization. Therefore, it is necessary to design an extruder with a multi-stage extrusion mechanism to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a squeeze dryer with a built-in multi-stage extrusion mechanism to solve the problem mentioned in the background art that it cannot meet the squeezing requirements of larger material blocks.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a desqueezing machine with a multi-stage extrusion mechanism, comprising a frame and a mounting frame, wherein the mounting frame is fixed at the top of the frame;

[0007] The frame houses a second motor, the output shaft of which is connected to a spiral extrusion rod. A movable frame is connected to one side of the mounting frame. A positioning groove is formed at the top of the mounting frame, and a pin is connected inside the positioning groove. A lead screw is connected to one side of the movable frame, and a crank is connected to one side of the lead screw. The lead screw is threadedly connected to the mounting frame. A telescopic rotating rod is connected inside the frame, and a first bevel gear and a sixth bevel gear are fixed to both sides of the telescopic rotating rod, respectively. A third bevel gear is fixed to one side of the telescopic rotating rod. A first motor is fixed inside the frame, and the output shaft of the first motor is connected to a rotating shaft. A fourth bevel gear is fixed to one end of the rotating shaft. A fixed extrusion roller is connected to the top of the frame. A movable extrusion roller is connected to the bottom of the movable frame. A second bevel gear is connected to one side of the fixed extrusion roller, and a fifth bevel gear is connected to one side of the movable extrusion roller.

[0008] Furthermore, a first water tank is connected to the bottom of the machine frame, and a second water tank is connected to the bottom of the machine frame. A handle is fixed to one side of both the first and second water tanks, and an anti-slip sleeve is fitted on the outside of the handle.

[0009] Furthermore, sliders are fixed on both sides of the bottom of the first water tank, and sliding grooves are fixed on both sides of the bottom of the frame, and the sliding grooves are connected to the sliders.

[0010] Furthermore, the width of each slider is matched with the width of the groove, and both the groove and the slider are symmetrically arranged about the central axis of the first water tank.

[0011] Furthermore, an electric push rod is fixed to the outer side of the frame on one side of the top of the second water tank, and a pressure block is fixed to the output end of the electric push rod. A discharge gate is provided on the outer side of the frame.

[0012] Furthermore, a feed hopper is fixed to the top of the mounting frame, and the top cross-section of the feed hopper is funnel-shaped.

[0013] Furthermore, the first bevel gear and the second bevel gear are meshed together, the fifth bevel gear and the sixth bevel gear are meshed together, and the fourth bevel gear is meshed together with the third bevel gear.

[0014] Furthermore, water troughs are provided inside the frame on the outer side of the spiral extrusion rod, and water troughs are provided inside the frame at the bottom of the pressing block.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the extruder with a built-in multi-stage extrusion mechanism realizes the functions of easy pretreatment and adjustment, and also realizes the function of multi-stage extrusion;

[0016] The extrusion zone, consisting of a fixed extrusion roller and a movable extrusion roller, is operated by a first motor. The motor transmits power through a rotating shaft, and the fourth and third bevel gears mesh to drive the telescopic rotating rod to rotate. The first bevel gear on the telescopic rotating rod meshes with the second bevel gear on the fixed extrusion roller, and the sixth bevel gear on the telescopic rotating rod meshes with the fifth bevel gear on the movable extrusion roller. This simultaneously drives the fixed and movable extrusion rollers to rotate, performing initial extrusion and crushing of the material to facilitate subsequent extrusion operations. Further rotation of the crank handle drives the lead screw to rotate. The lead screw is threaded into the movable frame, causing the movable frame to move along the lead screw axis. At the same time, the side of the telescopic rotating rod closest to the movable extrusion roller moves synchronously with the movable extrusion roller. By changing the position of the movable frame, the gap between the fixed and movable extrusion rollers is adjusted to accommodate materials with different hardness and moisture content, thereby controlling the degree of extrusion.

[0017] As the pre-processed material falls below, the second motor drives the spiral extrusion rod to rotate, and the material is squeezed a second time during the spiral propulsion. The liquid flows through the water tank into the first water tank; the solid continues to be conveyed to the end, where the pressure block can be pushed by the electric push rod to further compact and dehydrate the solid. Finally, the solid is discharged from the discharge gate, and the separated liquid flows into the second water tank, so that the material block is fully dehydrated and the solid and liquid are separated.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Please see Figures 1-5 The present invention provides an embodiment of a desqueezing machine with a multi-stage extrusion mechanism, comprising a frame 1 and a mounting frame 2;

[0027] A mounting bracket 2 is fixed to the top of the frame 1;

[0028] The bottom of the machine frame 1 is connected to the first water tank 16, and the bottom of the machine frame 1 is connected to the second water tank 17. A handle is fixed on one side of both the first water tank 16 and the second water tank 17, and the outside of the handle is covered with an anti-slip sleeve. A water groove is opened inside the machine frame 1 on the outside of the spiral extrusion rod 21. A water groove is opened inside the machine frame 1 at the bottom of the pressure block 20. An electric push rod 18 is fixed on the outside of the machine frame 1 on the top side of the second water tank 17, and the output end of the electric push rod 18 is fixed to the pressure block 20. A discharge gate 19 is provided on the outside of the machine frame 1. A slider 28 is fixed on both sides of the bottom of the first water tank 16. A sliding groove 22 is fixed on both sides of the bottom of the machine frame 1, and the sliding groove 22 is connected to the slider 28. The width of the slider 28 matches the width of the sliding groove 22. The sliding groove 22 and the slider 28 are symmetrically arranged about the central axis of the first water tank 16.

[0029] Specifically, such as Figure 1 , Figure 2 and Figure 5As shown, during use, the installation of the handle facilitates the pulling out of the water tank to process the squeezed liquid, while the slide 22 limits the slider 28. The electric push rod 18 pushes the pressure block 20 to squeeze the material a second time, fully dehydrating it. The water tank setting is more conducive to the squeezing of the material and the recycling of wastewater.

[0030] The top of the mounting frame 2 is fixed with a feed hopper 3, and the top section of the feed hopper 3 is shaped like a trumpet.

[0031] Specifically, such as Figure 1 and Figure 2 As shown, the funnel-shaped cross-section makes it easier to deliver materials and improves work efficiency during use.

[0032] The machine frame 1 is equipped with a second motor 15, and the output shaft of the second motor 15 is connected to a spiral extrusion rod 21. A movable frame 24 is connected to one side of the mounting frame 2. A positioning groove 4 is opened at the top of the mounting frame 2, and a pin 5 is connected inside the positioning groove 4. A lead screw 6 is connected to one side of the movable frame 24, and a crank 7 is connected to one side of the lead screw 6. The lead screw 6 is threadedly connected to the mounting frame 2. A telescopic rotating rod 11 is connected inside the machine frame 1, and a first bevel gear 8 and a sixth bevel gear 27 are fixed on both sides of the telescopic rotating rod 11 respectively.

[0033] The first bevel gear 8 and the second bevel gear 9 are meshed and connected; the fifth bevel gear 26 and the sixth bevel gear 27 are meshed and connected; and the fourth bevel gear 13 is meshed and connected with the third bevel gear 10.

[0034] Specifically, such as Figure 1 and Figure 4 As shown, during use, the meshing between the bevel gears better realizes the transmission of the mechanism, which in turn drives the rotation of the fixed extrusion roller 23 and the moving extrusion roller 25 to extrude and crush the material;

[0035] A third bevel gear 10 is fixed to one side of the telescopic rotating rod 11. A first motor 14 is fixed inside the frame 1, and the output shaft of the first motor 14 is connected to a rotating shaft 12. A fourth bevel gear 13 is fixed to one end of the rotating shaft 12. A fixed extrusion roller 23 is connected to the top of the inside of the frame 1. A movable extrusion roller 25 is connected to the bottom of the movable frame 24. A second bevel gear 9 is connected to one side of the fixed extrusion roller 23, and a fifth bevel gear 26 is connected to one side of the movable extrusion roller 25.

[0036] Working principle: When this utility model is in use, the material is first fed into the feeding hopper 3 and enters the extrusion area composed of the fixed extrusion roller 23 and the moving extrusion roller 25. The first motor 14 is turned and transmitted through the rotating shaft 12. The fourth bevel gear 13 meshes with the third bevel gear 10, which drives the telescopic rotating rod 11 to rotate. The first bevel gear 8 on the telescopic rotating rod 11 meshes with the second bevel gear 9 on the fixed extrusion roller 23, and the sixth bevel gear 27 on the telescopic rotating rod 11 meshes with the fifth bevel gear 26 on the moving extrusion roller 25. At the same time, the fixed extrusion roller 23 and the moving extrusion roller 25 are driven to rotate, so as to perform preliminary extrusion and crushing of the material.

[0037] Secondly, the crank 7 is further rotated to drive the lead screw 6 to rotate. The lead screw 6 is threadedly engaged with the moving frame 24, causing the moving frame 24 to move axially along the lead screw 6. At the same time, the telescopic rotating rod 11 moves synchronously with the moving extrusion roller 25 on the side close to the moving extrusion roller 25. By changing the position of the moving frame 24, the gap between the fixed extrusion roller 23 and the moving extrusion roller 25 is adjusted.

[0038] Finally, when the pre-processed material falls below, the second motor 15 drives the spiral extrusion rod 21 to rotate. The material is squeezed a second time during the spiral propulsion. The liquid flows into the first water tank 16 through the water tank. The solid continues to be conveyed to the end. At the end, the pressure block 20 can be pushed by the electric push rod 18 to further compact and dehydrate the solid. Finally, the solid is discharged from the discharge gate 19, and the separated liquid flows into the second water tank 17.
