Description

Technical Field

[0001] This utility model relates to the field of briquetting equipment technology, and in particular to a sludge briquetting equipment for sludge resource utilization. Background Technology

[0002] Sludge briquettes are solid products with a certain strength and shape made by mixing sludge with high water content and appropriate amounts of solidifying agents, flocculants and other additives under high pressure using mechanical pressurization equipment. This can significantly reduce the water content of sludge, making it easier to transport and dispose of. Some existing sludge briquetting equipment, after extruding and molding the sludge, uses a rotating turntable to transport the sludge blocks to the discharge port, thus testing the sludge block feeding operation. For example, Chinese utility model patent CN214137487U discloses a briquetting device for biomass fuel processing. This application includes a feeding pipe, a separating rod, and a second rotating shaft. The bottom of the feeding pipe is connected to a feed inlet, and a surrounding plate is provided on one side of the feed inlet. One end of a fixing block is connected to a first rotating shaft, one end of a brush is connected to a slider, and a groove is provided on one side of the slider. One end of a first baffle is connected to a locking block, and a locking groove is provided on one side of the locking block. A second baffle is provided inside the surrounding plate. However, this application is similar to some existing sludge briquetting equipment. The lack of a cutting function for extruded sludge blocks means that longer sludge blocks cannot be cut into suitable sizes after being discharged directly from the extrusion chamber. When the length of the sludge block exceeds the spacing or gap of the discharge port baffle, due to its own viscosity and toughness, the drooping part under gravity is prone to frictional resistance with the edge of the baffle. As subsequent sludge blocks are continuously extruded and discharged, the longer sludge blocks at the front end will gradually accumulate at the baffle. Furthermore, the baffle is usually used to control the discharge speed and direction. When the length of the sludge block exceeds the baffle's design capacity, its end will abut against the inside of the baffle or get stuck at the angle between the baffle and the extrusion outlet. Especially when the equipment is running continuously, the accumulated sludge blocks will squeeze each other, further aggravating the jamming phenomenon. Utility Model Content

[0003] The purpose of this invention is to provide a sludge briquetting device for sludge resource utilization, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A sludge briquetting device for sludge resource utilization includes a workbench, a controller fixedly installed on one side of the workbench, a briquetting box fixedly installed on the top of the workbench, multiple discharge ports on the outside of the briquetting box, a feed hopper fixedly installed on the top of the briquetting box, a protective cover fixedly installed on the outside of the briquetting box, a feeding turntable movably installed between the protective cover and the briquetting box, two limiting clamps fixedly installed on the briquetting box located between the feeding turntable and the discharge ports, two semi-circular cutting blades movably installed between the two limiting clamps and the briquetting box, and multiple push rods fixedly installed at the bottom of the two semi-circular cutting blades respectively.

[0005] As a further preferred embodiment of this utility model, the inner side of the feeding turntable is provided with a toothed groove, the top of the feeding turntable is fixedly installed with a base, the top of the base is fixedly installed with multiple slope blocks, and the feeding turntable is rotatably installed inside the bottom of the protective cover by the ball bearings at the bottom. The toothed groove is meshed with the gear mechanism on the outside of the transmission shaft inside the briquetting box, so that the feeding turntable can be rotatably installed inside the protective cover by the power of the briquetting box itself, thereby enabling the top of the feeding turntable to realize the synchronous reciprocating lifting and lowering of two semi-circular cutting blades through the multiple slope blocks.

[0006] As a further preferred embodiment of this utility model, the limiting hoop has multiple mounting slots, and limiting blocks are installed in the mounting slots. One side of the limiting block also abuts against the outside of the pressing box and is fixed with screws. The two limiting hoops can be installed on the outside of the pressing box through the setting of multiple limiting blocks, and provide conditions for guiding the semi-circular cutting knife to move.

[0007] As a further preferred embodiment of this utility model, the semi-circular cutting blade is provided with multiple sliding grooves, and the semi-circular cutting blade is inserted and installed between the limiting hoop and the pressure block box. The sliding grooves are also slidably installed on the corresponding limiting blocks.

[0008] As a further preferred embodiment of this utility model, an outer flange is fixedly installed on the outer side of the semi-circular cutting blade. A positioning groove is opened at the bottom of the outer flange, and multiple fixed shafts are fixedly installed on the top of the outer flange. The top of the fixed shaft is inserted into the through groove at the bottom of the limiting hoop. A compression spring is also fitted on the fixed shaft located between the limiting hoop and the outer flange. Multiple protective covers are also movably connected between the limiting hoop and the outer flange, and the fixed shaft is placed in the corresponding protective cover. The outer flange is provided on the outer side of the semi-circular cutting blade, and the fixed shaft is provided on the outer flange. The protective cover is fitted on the outer side of the fixed shaft. This allows the semi-circular cutting blade to be pushed upward with the cooperation of the top rod and the slope block, and the force of the compression spring ensures that the semi-circular cutting blade can be reset normally.

[0009] As a further preferred embodiment of this utility model, a positioning block is fixedly installed on the top of the top rod. The positioning block is inserted into the corresponding positioning groove. By adjusting the number of top rods installed at the bottom of the outer flange, the frequency of the reciprocating motion of the semi-circular cutting blade can be adjusted, thereby adjusting the cutting length of the mud block.

[0010] Compared with the prior art, the present invention has the following beneficial effects: In this invention, a semi-circular cutting blade linked to the feeding turntable is installed on the outside of the briquetting box. When the sludge blocks are discharged from the outlet, the feeding turntable rotates, causing the top slope block to push the top rod, so that the semi-circular cutting blade slides along the limiting hoop and the limiting block. The elastic reset of the compression spring is used to realize the automatic cutting of the sludge blocks, avoiding the accumulation of long sludge blocks. The cooperation between the top rod and the positioning groove can adjust the cutting frequency to adapt to different size requirements. Attached Figure Description

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] like Figures 1-5As shown, the present invention provides a sludge briquetting device for sludge resource utilization, including a workbench 1, a controller 2 fixedly installed on one side of the workbench 1, a briquetting box 3 fixedly installed on the top of the workbench 1, multiple discharge ports 7 opened on the outside of the briquetting box 3, a feed hopper 5 fixedly installed on the top of the briquetting box 3, a protective cover 4 fixedly installed on the outside of the briquetting box 3, a feeding turntable 6 movably installed between the protective cover 4 and the briquetting box 3, two limiting hoops 8 fixedly installed between the feeding turntable 6 and the discharge ports 7, two semi-circular cutting blades 9 movably installed between the two limiting hoops 8 and the briquetting box 3, and multiple top rods 10 fixedly installed at the bottom of the two semi-circular cutting blades 9 respectively.

[0015] like Figures 1-2 As shown, the inner side of the feeding turntable 6 is provided with a toothed groove 11, and a base 12 is fixedly installed on the top of the feeding turntable 6. Multiple slope blocks 13 are fixedly installed on the top of the base 12. The feeding turntable 6 is rotated and installed at the bottom of the protective cover 4 by the ball bearings at the bottom. The toothed groove 11 is meshed with the gear mechanism on the outside of the transmission shaft in the briquetting box 3, so that the feeding turntable 6 is rotated and installed in the protective cover 4. It can be driven by the power of the briquetting box 3 itself, so that the top of the feeding turntable 6 can realize the synchronous reciprocating lifting and lowering of the two semi-circular cutting blades 9 through the multiple slope blocks 13.

[0016] like Figures 3-5As shown, the limiting clamp 8 has multiple mounting slots 14, and limiting blocks 15 are inserted into the mounting slots 14. One side of the limiting block 15 also abuts against the outside of the pressing box 3 and is fixed with screws. The two limiting clamps 8 can be installed on the outside of the pressing box 3 through the setting of multiple limiting blocks 15, and provide conditions for guiding the movement of the semi-circular cutting blade 9. The semi-circular cutting blade 9 has multiple sliding grooves 16, and the semi-circular cutting blade 9 is inserted between the limiting clamp 8 and the pressing box 3. The sliding grooves 16 are also slidably installed on the corresponding limiting blocks 15. An outer flange 17 is fixedly installed on the outside of the semi-circular cutting blade 9. A positioning groove 18 is opened at the bottom of the outer flange 17. Multiple fixing shafts 20 are fixedly installed on the top of the outer flange 17. The top of the fixing shafts 20 is inserted into the through groove at the bottom of the limiting clamp 8, located between the limiting clamp 8 and the outer flange. The fixed shaft 20 between 17 is also fitted with a compression spring 21. The limiting hoop 8 and the outer flange 17 are also movably connected with multiple protective covers 22, and the fixed shaft 20 is placed in the corresponding protective cover 22. The outer flange 17 is provided on the outside of the semi-circular cutting knife 9, and the fixed shaft 20 is provided on the outer flange 17. The protective cover 22 is fitted on the outside of the fixed shaft 20, so that after the semi-circular cutting knife 9 is pushed up by the cooperation of the top rod 10 and the slope block 13, the force of the compression spring 21 ensures that the semi-circular cutting knife 9 is reset normally. The top of the top rod 10 is fixedly installed with a positioning block 19, which is inserted into the corresponding positioning groove 18. By adjusting the number of top rods 10 installed at the bottom of the outer flange 17, the frequency of the reciprocating motion of the semi-circular cutting knife 9 can be adjusted, thereby adjusting the cutting length of the mud block.

[0017] It should be noted that this utility model is a sludge briquetting device for sludge resource utilization. Sludge enters the briquetting box 3 through the feed hopper 5, is compressed into briquettes by the internal pressure mechanism, and is discharged from the discharge port 7. At this time, the gear mechanism on the outside of the transmission shaft inside the briquetting box 3 drives the bottom tooth groove 11 of the feeding turntable 6 to rotate, so that the feeding turntable 6 rotates smoothly inside the protective cover 4 through the bottom ball bearings. The slope block 13 on its top base 12 rotates synchronously with the turntable. When the slope block 13 rotates to contact the top rod 10, its slope structure pushes the top rod 10 to move upward. The top positioning block 19 of the top rod 10 drives the outer flange 17 and the semi-circular cutting blade 9 to move upward, and the fixed shaft 20 moves into the through groove at the bottom of the limiting hoop 8. At this time, the compression spring 21 is compressed, and the inner blade of the semi-circular cutting knife 9 cuts the sludge block discharged from the discharge port 7. The cut sludge block falls on the top of the feeding turntable 6 and is discharged to the next position as the turntable rotates. When the slope block 13 rotates past the top rod 10, the compression spring 21 releases its elastic force, pushing the outer flange 17 and the semi-circular cutting knife 9 to reset downwards along the slide groove 16 on the limit block 15. The fixed shaft 20 falls back synchronously, so that the semi-circular cutting knife 9 returns to the initial position and waits for the next cutting action.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
