Description
Technical Field
[0001] The utility model belongs to the technical field of papermaking and pulping equipment, in particular to a horizontal screening separator. Background Art
[0002] At present, in order to meet the requirements of their own processing technology, industries such as pulping and papermaking, wood-based panel manufacturing, etc. usually need to use screening machinery to process the purchased waste paper, wood chips, bamboo chips and other raw materials into pulp, and then screen them, and then use suitable pulp for production. Separator is one of the most commonly used screening equipment in the pulping and papermaking industry. Now most of the pulping in paper mills is completed through the coarse screening process and the fine screening process. The commonly used equipment is a vertical separator. The two ends of the rotor shaft are installed at the upper and lower ends of the shell through the bearing seat. Since the bearing seat is located in the shell, especially the lower bearing seat, it needs to be pressure-bearing and sealed. The bearing seat also needs lubrication and cooling in the shell, which is difficult to maintain. In addition, the shell is provided with multiple pulp outlets from top to bottom, connecting many pipelines. Once the lower parts need to be maintained, all the upper pipelines need to be removed before the shell can be disassembled, which is time-consuming and labor-intensive, and the maintenance cost is high.
[0003] Therefore, in the technical field of papermaking and pulping equipment, there is still a need for research and improvement of horizontal screening separators, which is also a research hotspot and focus in the current technical field of papermaking and pulping equipment, and is also the starting point for the completion of the present utility model. Utility Model Content
[0004] Therefore, the technical problem to be solved by the utility model is to provide a horizontal screening separator to solve the technical problem of high maintenance cost of the screening separator.
[0005] To solve the above technical problems, the technical solution of the utility model is: a horizontal screening separator, comprising a shell body arranged axially horizontally, a slurry inlet being provided at one end of the shell body, and a slag outlet being provided at the other end, a screen drum being fixedly mounted on the inner wall of the shell body, a transmission shaft driven by a power device being rotatably mounted in the shell body, a columnar rotor body being provided on the transmission shaft, a plurality of groups of rotors being provided on the outer peripheral surface of the rotor body, each group of the rotors comprising a plurality of wing seats protruding from the rotor body, two adjacent wing seats being arranged alternately in the axial direction of the rotor body, a water inlet and a slurry outlet being provided on the shell body corresponding to each group of the rotors, the water inlet being located at an upstream position of the wing seat in the group of rotors close to the slurry inlet, and the slurry outlet being located at a relative position of the wing seat in the group of rotors far away from the slurry inlet, both ends of the transmission shaft passing through the shell body and bearing seats being installed at the ends, a sealing filler being installed between the transmission shaft and the shell body.
[0006] As an improvement, the water inlet direction of the water inlet is consistent with the tangent direction of the shell.
[0007] As a further improvement, the shell includes an upper half and a lower half, and the upper half and the lower half are connected by a fastener.
[0008] As a further improvement, the slurry inlet, slag outlet, water inlet and slurry outlet are all arranged on the lower body.
[0009] As a further improvement, the shell includes a left half, a right half and several intermediate bodies arranged along the axial direction, the intermediate body is located between the left half and the right half, and the left half, the intermediate body and the right half are connected in sequence by fasteners.
[0010] As a further improvement, the slurry inlet is arranged on the right half body, the slag outlet is arranged on the left half body, and each group of the water inlet and slurry outlet is correspondingly arranged on the corresponding intermediate body.
[0011] After adopting the above technical solution, the beneficial effects of the utility model are:
[0012] Both ends of the transmission shaft of the utility model embodiment pass through the housing and bearing seats are installed at the ends. The bearing seats are arranged outside the housing, which solves the technical problem that the bearings of the vertical equipment are located in the housing, resulting in great difficulty and high maintenance costs. It is easy to lubricate and cool, reduces the number of bearing maintenance times, and extends the service life of the bearings. A sealing packing is installed between the transmission shaft and the housing. Compared with traditional vertical equipment, only sealing packing is required to achieve the sealing between the housing and the transmission shaft, without the need to meet the stringent sealing requirements of the bearing chamber, thereby reducing the equipment manufacturing requirements and further reducing the equipment manufacturing and maintenance costs.
[0013] Since the shell includes an upper body and a lower body, the slurry inlet, slag outlet, water inlet and slurry outlet are all arranged on the lower body, and the pipeline connections are all arranged on the lower body. During maintenance, the upper body can be easily opened to clean or replace the screen drum or wing seat, which reduces the labor intensity of the operator, saves maintenance time, and reduces maintenance costs.
[0014] Since the shell includes a left half body, a right half body and a plurality of intermediate bodies arranged along the axial direction, during maintenance, only the part that needs to be maintained is removed, and other parts do not need to be disassembled, which reduces the labor intensity of the operator, saves maintenance time and reduces maintenance costs.

[0023] Embodiment 1:
[0024] like Figure 1As shown, the utility model provides a horizontal screening separator, including a shell 1 arranged axially horizontally to form a horizontal structure. Different from the traditional vertical equipment, the shell 1 is provided with a slurry inlet 101 at one end and a slag outlet 102 at the other end. A screen drum 2 is fixedly installed on the inner wall of the shell 1. A transmission shaft 3 driven by a power device is rotatably installed in the shell 1. The power device is usually a belt transmission device driven by a motor. The device is a common technology in the field and will not be described here. A columnar rotor body 4 is provided on the transmission shaft 3. The rotor body 4 The outer peripheral surface of the rotor body 4 is provided with a plurality of groups of rotor blades, and the plurality of groups of rotor blades are arranged at intervals in the axial direction of the rotor body 4. Each group of rotor blades includes a plurality of wing seats 5 protruding from the rotor body 4. Two adjacent wing seats 5 are arranged alternately in the axial direction of the rotor body 4, thereby avoiding the long residence time of impurities and the unsmooth slag discharge, solving the problem that the impurities block the screen of the screen drum 2 and cause the wing seats 5 to wear seriously, and reducing the maintenance cost. The housing 1 is provided with a water inlet 103 and a slurry outlet 104 corresponding to each group of rotor blades, and each group of water inlet 103 and slurry outlet 104 is located at the housing 1, respectively. On both sides of 1, the water inlet 103 is located at the upstream position of the wing seat 5 close to the slurry inlet 101 in the group of rotors, and the slurry outlet 104 is located at the relative position of the wing seat 5 far away from the slurry inlet 101 in the group of rotors. The setting of the water inlet 103 realizes the dilution of the slurry screened at each level, improves the speed of the tailings, and solves the problem of the tailings staying in the screening area. After multi-level screening, slurries with different particle sizes can be obtained, and the coarse slurry and the refined slurry can be stored separately. Both ends of the transmission shaft 3 pass through the shell 1 and the ends are equipped with bearing seats 6. The bearing seats 6 are arranged outside the shell 1, which solves the technical problem that the bearing of the vertical equipment is located in the shell 1, which makes maintenance difficult and the maintenance cost high. It is convenient for lubrication and cooling, reduces the number of bearing maintenance, and prolongs the service life of the bearing. A sealing packing 7 is installed between the transmission shaft 3 and the shell 1. Compared with the traditional vertical equipment, only the sealing packing 7 is required to achieve the sealing between the shell 1 and the transmission shaft 3, without meeting the stringent sealing requirements of the bearing chamber, reducing the equipment manufacturing requirements, and thus reducing the equipment manufacturing and maintenance costs.
[0025] The water inlet direction of the water inlet 103 is consistent with the tangential direction of the shell 1. On the one hand, the slurry concentration can be diluted. On the other hand, the tangential water inlet can accelerate the slurry fluidity, which is beneficial to screening and tailings discharge.
[0026] The slurry enters the shell 1 from the slurry inlet 101, and the power device drives the rotor body 4 to rotate. The slurry is screened between the wing seat 5 and the screen drum 2, and slurries of different particle sizes are discharged from the corresponding slurry outlets 104. The upstream slurry outlet 104 discharges coarse slurry with a particle size between 1.2 mm and 2.5 mm. The slurry becomes finer as it goes downstream. The tail end slurry outlet 104 discharges refined slurry with a particle size between 0.12 and 0.25, and the tailings are discharged from the slag outlet 102.
[0027] Embodiment 2:
[0028] The utility model provides a horizontal screening separator, the structure of which is basically the same as that of the first embodiment, except that Figure 2 As shown, the shell 1 includes an upper body 9 and a lower body 8, and the upper body 9 and the lower body 8 are connected by fasteners. The slurry inlet 101, the slag outlet 102, the water inlet 103 and the slurry outlet 104 are all arranged on the lower body 8, and the pipeline connections are all arranged on the lower body 8. During maintenance, the upper body 9 can be easily opened to clean or replace the screen drum 2 or the wing seat 5, which reduces the labor intensity of the operator, saves maintenance time, and reduces maintenance costs.
[0029] Embodiment three:
[0030] The utility model provides a horizontal screening separator, the structure of which is basically the same as that of the first embodiment, except that Figure 3 As shown, the shell 1 includes a left half body 11, a right half body 10 and a plurality of intermediate bodies 12 arranged along the axial direction, the intermediate body 12 is located between the left half body 11 and the right half body 10, the left half body 11, the intermediate body 12 and the right half body 10 are connected in sequence by fasteners, the slurry inlet 101 is arranged on the right half body 10, the slag outlet 102 is arranged on the left half body 11, and each group of water inlet 103 and slurry outlet 104 is correspondingly arranged on the corresponding intermediate body 12. When this structure is maintained, the part that needs to be maintained is removed, and the other parts do not need to be disassembled, which reduces the labor intensity of the operator, saves maintenance time, and reduces maintenance costs.
[0031] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model.
