Description

Technical Field

[0001] This utility model relates to the field of pulp and paper technology, specifically to a spiral extruder. Background Technology

[0002] Before treatment, wastewater from pulp and paper making is usually subjected to dewatering treatment to remove suspended solids and some organic matter, reduce the concentration of pollutants in the wastewater, make it easier to carry out subsequent biological or chemical treatment, and reduce the volume of wastewater.

[0003] The waste material generated after extrusion and dewatering of pulp and paper wastewater and waste pulp has insufficient discharge continuity and insufficient density in the discharged and piled state. It occupies a large volume in the material bag and a large area in the transport vehicle, resulting in high transportation costs. Therefore, a screw extruder is proposed. Summary of the Invention

[0004] To address the problems in the existing technology, this utility model provides a spiral extruder to provide a set of extrusion mechanisms for the compaction of waste residue generated from pulping and papermaking. This facilitates better compaction of the waste residue obtained during extrusion and dewatering, resulting in a smaller accumulation volume of the collected waste residue. This improves the convenience of waste residue collection and transportation and reduces transportation costs.

[0005] The technical solution adopted by this utility model to solve its technical problem is a spiral slag extruder, including a slag extrusion component and a compaction component. The compaction component is disposed at the discharge end of the slag extrusion component. The slag extrusion component includes a frame and a material cylinder disposed at the top of the frame. A spiral rod is disposed inside the material cylinder. The two ends of the spiral rod are rotatably connected to the material cylinder through bearings. A metal mesh sleeve is sleeved around the outer periphery of the spiral rod. The metal mesh sleeve is fixedly connected to the material cylinder. A protective cover is disposed around the outer periphery of the metal mesh sleeve. The bottom of the protective cover is fixedly connected to the frame. A slag discharge port is opened at the discharge end of the metal mesh sleeve and at the neck of the material cylinder.

[0006] By adopting the above technical solution, a slag extrusion mechanism composed of a slag extrusion component and a densification component is provided for the wastewater generated in pulping and papermaking, which can densify the waste residue. This makes it easier to collect the waste residue after extrusion and dewatering, resulting in a smaller accumulation volume of the waste residue after collection. This improves the convenience of waste residue collection and transportation and reduces transportation costs.

[0007] Specifically, a shaft is provided at the bottom of one side of the frame, and a motor is installed at the bottom inside the frame. The drive end of the motor and the rotating shaft of the screw are respectively equipped with a first synchronous pulley and a second synchronous pulley. The first synchronous pulley and the second synchronous pulley are connected by a synchronous belt.

[0008] A third synchronous pulley is installed at one end of the shaft and at the center of one side of the second synchronous pulley, and the third synchronous pulleys are connected to each other by a synchronous belt.

[0009] By adopting the above technical solution, and through the arrangement of the motor, the first synchronous pulley, the second synchronous pulley, and the third synchronous pulley, the driving force and transmission force for the operation of the slag extrusion assembly and the compaction assembly are realized, so that the screw and the shaft can rotate.

[0010] Specifically, the dense component includes a base and a material box disposed on the base. Guide rods are connected to the bottom corners of the material box and inserted into the top corners of the base. Springs are sleeved on the outer periphery of the guide rods. The two ends of the springs are connected to the base and the material box, respectively. Support wheels are provided on both sides of the bottom of the material box, and wheel grooves corresponding to the support wheels are opened on both sides of the top of the base.

[0011] By adopting the above technical solution and setting up a dense component, the waste residue discharged from the slag extrusion component can be vibrated to rearrange the waste residue particles, reduce the gaps between the waste residue particles, make them more compact, and ensure the compactness of the waste residue after it is discharged and piled up.

[0012] Specifically, cams are symmetrically arranged on both sides of the base. The cams contact the bottom of the support wheel. A crossbar is installed at the center of the cam via a key pin. Both ends of the crossbar are rotatably connected to the base via bearings. A fourth synchronous pulley is provided at one end of the crossbar and at the end of the shaft away from the third synchronous pulley. The fourth synchronous pulleys are connected to each other via a synchronous belt.

[0013] By adopting the above technical solution, through the setting of the cam, after the shaft rotates, the fourth synchronous wheel synchronously drives the crossbar and the cam on the crossbar to rotate. The rotating cam, based on its irregular circle characteristics, will repeatedly push the support wheel at the bottom of the material box, thereby causing the material bag fitted on the material box to be vibrated, thus achieving the vibration and densification treatment of the waste slag that falls into the material bag.

[0014] Specifically, a discharge hopper is provided on the frame and at the bottom of the protective cover, and a drain pipe is connected to the bottom of the discharge hopper.

[0015] Specifically, a feed hopper is provided at the top of the end of the material cylinder away from the metal mesh sleeve.

[0016] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0017] This system, consisting of a slag extrusion component and a densification component, provides a slag extrusion mechanism for the wastewater generated in pulping and papermaking, enabling the densification of the waste slag obtained during extrusion and dewatering. This results in a smaller accumulated volume of the waste slag after collection, thereby improving the convenience of waste slag collection and transportation. It also solves the problem that existing pulping and papermaking wastewater and pulp, after extrusion and dewatering, produce slag with insufficient discharge continuity, insufficient density in the discharged and accumulated state, occupying a large volume in the material bag, and requiring a large area of ​​transport vehicle, leading to high transportation costs.

[0026] like Figure 1-5As shown, the present invention discloses a spiral slag extruder, comprising an extrusion assembly 1 and a compaction assembly 2. The compaction assembly 2 is disposed at the discharge end of the extrusion assembly 1. The extrusion assembly 1 includes a frame 11 and a material cylinder 12 disposed at the top of the frame 11. A spiral rod 13 is disposed inside the material cylinder 12. Both ends of the spiral rod 13 are rotatably connected to the material cylinder 12 via bearings. A metal mesh sleeve 14 is fitted around the outer periphery of the spiral rod 13. The metal mesh sleeve 14 is fixedly connected to the material cylinder 12.

A slag discharge port 16 is provided at the discharge end of the metal mesh sleeve 14 and at the neck of the material cylinder 12.

[0027] The present invention also includes a shaft 123 provided at the bottom of one side of the frame 11, a motor 120 installed at the bottom inside the frame 11, and a first synchronous pulley 121 and a second synchronous pulley 122 respectively installed at the drive end of the motor 120 and the rotation shaft of the screw rod 13. The first synchronous pulley 121 and the second synchronous pulley 122 are connected by a synchronous belt.

[0028] A third synchronous pulley 124 is installed at one end of the shaft 123 and at the center of one side of the second synchronous pulley 122, and the third synchronous pulleys 124 are connected to each other by a synchronous belt.

[0029] In use, based on the arrangement of motor 120, first synchronous pulley 121, second synchronous pulley 122 and third synchronous pulley 124, driving force and transmission force are provided for the operation of slag extrusion assembly 1 and compaction assembly 2, so that screw rod 13 and shaft rod 123 can rotate.

[0030] This utility model also includes a dense component 2 comprising a base 21 and a material box 22 disposed on the base 21. A guide rod 23 is connected to the bottom corner of the material box 22. The guide rod 23 is inserted into the top corner of the base 21. A spring 231 is sleeved on the outer periphery of the guide rod 23. The two ends of the spring 231 are connected to the base 21 and the material box 22 respectively. Support wheels 24 are respectively disposed on both sides of the bottom of the material box 22. Wheel grooves 25 corresponding to the support wheels 24 are opened on both sides of the top of the base 21.

[0031] When in use, the compaction component 2 can be used to vibrate the waste slag discharged from the slag extrusion component 1, causing the waste slag particles to rearrange, reducing the gaps between the waste slag particles, making them more compact, and ensuring the compactness of the waste slag after it is discharged and piled up.

[0032] The present invention also includes cams 26 symmetrically arranged on both sides of the base 21. The cams 26 are in contact with the bottom of the support wheel 24. A crossbar 27 is installed at the center of the cam 26 through a key pin. The two ends of the crossbar 27 are rotatably connected to the base 21 through bearings. A fourth synchronous wheel 28 is provided at one end of the crossbar 27 and at the end of the shaft 123 away from the third synchronous wheel 124. The fourth synchronous wheels 28 are connected to each other by a synchronous belt.

[0033] In use, based on the setting of cam 26, after the shaft 123 rotates, the fourth synchronous wheel 28 synchronously drives the crossbar 27 and the cam 26 on the crossbar 27 to rotate. The rotating cam 26, based on its irregular circle characteristics, will repeatedly push the support wheel 24 at the bottom of the material box 22, so that the material bag fitted on the material box 22 for storing waste residue can be vibrated, thereby achieving vibration and densification of the waste residue that falls into the material bag.

[0034] The present invention also includes a discharge hopper 17 provided on the frame 11 and located at the bottom of the protective cover 15, and a drain pipe 18 connected to the bottom of the discharge hopper 17.

[0036] In use, the power supply unit at the work site provides power to the motor 120. The bag containing the waste residue is placed in the material box 22, and the bag opening is fitted onto the opening of the material box 22. The motor 120 drives the first synchronous wheel 121 and the second synchronous wheel 122 to rotate, causing the screw rod 13 and the shaft 123 to rotate simultaneously. During the slag extrusion process, the wastewater to be extruded is fed into the material cylinder 12 through the feed hopper 19. The rotating screw rod 13 continuously pushes the wastewater towards the metal mesh sleeve 14. The wastewater is filtered and discharged through the metal mesh sleeve 14 into the discharge hopper 17, and then drained through the drain pipe 18. The waste residue filtered and retained in the metal mesh sleeve 14 is continuously pushed out of the slag discharge port 16 by the screw rod 13 and falls into the material bag fitted on the material box 22. Based on the setting of the cam 26, after the shaft 123 rotates, the fourth synchronous wheel 28 synchronously drives the crossbar 27 and the cam 26 on the crossbar 27 to rotate. The rotating cam 26, based on its irregular circle characteristics, will repeatedly push the support wheel 24 at the bottom of the material box 22, so that the material bag fitted on the material box 22 for storing waste residue can be vibrated, thereby achieving vibration and densification treatment of the waste residue accumulated in the material bag.

[0037] The opening of the material bin 22 can be rectangular or circular.
