Description

Technical Field

[0001] The utility model relates to the technical field of cotton pulp production, in particular to a slag removal device used for producing pure cotton pulp. Background Art

[0002] Cotton pulp, also known as refined cotton pulp, is a high-purity cellulose made from cotton linters through alkaline cooking, rinsing and refining. It is mainly used to manufacture cellulose acetate, nitrocellulose and other celluloses. It is widely used in food, medicine, toothpaste, daily chemicals, building materials, papermaking, electronics, plastics, aerospace and military industries. Cotton pulp purification is an important link in the production process of cotton pulp.

[0003] The slag removal device in the prior art usually includes a slag removal device shell, a feed head is installed on the top of the slag removal device shell, a good pulp discharge pipe is provided on the feed head, a pulp inlet pipe is provided along the tangent direction of the feed head, a pulp saver is installed at the bottom of the slag removal device shell, a cut-off valve is provided between the slag removal device shell and the pulp saver, a slag discharge valve is provided at the bottom of the pulp saver, an air exhaust pipe and a flushing water pipe are provided on the pulp saver, an exhaust valve is provided on the air exhaust pipe, and a control valve for controlling the on-off of the pipeline is provided on the flushing water pipe. Specifically, after the slurry is fed into the pulp inlet pipe by the pulp inlet pump, the slurry enters the slag removal device along the tangent direction. High-speed rotation generates centrifugal force to separate the fibers. The cotton pulp deslagging device uses centrifugal action to remove slag. The impurities in cotton pulp are divided into light slag and heavy slag. Due to the difference in mass and density of the two impurities, indiscriminate use of the same method to remove slag cannot achieve a good slag removal effect. At the same time, if you want to achieve a good centrifugal deslagging effect, the machine body needs to maintain a very stable state when working. The cotton pulp deslagging devices currently on the market have a large vibration amplitude when working, which not only easily causes damage to the device, but also greatly reduces the effect of the device's centrifugal deslagging.

[0004] Therefore, it is particularly important to design a slag removal device for producing pure cotton pulp to solve the above-mentioned defects. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] Example:

[0022] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0023] A slag removal device for producing pure cotton pulp comprises a base 1, a slag removal cylinder 2 is installed on the top of the base 1, a pulp inlet pipe 3 is installed on the top of the slag removal cylinder 2, a filter cylinder 4 is installed at the center of the inside of the slag removal cylinder 2, a partition cover 5 is installed inside the slag removal cylinder 2 and located on the outside of the filter cylinder 4, a guide cover 6 is installed inside the slag removal cylinder 2 and located between the slag removal cylinder 2 and the partition cover 5, a first filter chamber 7 is formed between the guide cover 6 and the slag removal cylinder 2, a heavy residue outlet pipe 8 is installed on the outside of the first filter chamber 7 located on the outside of the slag removal cylinder 2, a second filter chamber 9 is formed between the filter cylinder 4 and the partition cover 5, a pulp outlet pipe 10 is installed on the outside of the second filter chamber 9 located on the outside of the slag removal cylinder 2, a rotating shaft 11 is installed at the center of the bottom of the slag removal cylinder 2, and the rotating shaft 11 extends to the inside of the base 1, and a shock absorbing assembly 12 is installed on the outside of the rotating shaft 11 and located inside the base 1.

[0024] First, moving wheels 101 are installed at the four corners of the bottom of the base 1, a driving motor 102 is installed on the left side of the base 1, a protective cover 103 is installed on the outside of the slag removal barrel 2 and on the driving end of the driving motor 102, a driving wheel 104 is installed on the driving end of the driving motor 102, and a transmission wheel 105 is fixedly installed on the outside of the rotating shaft 11 and below the partition cover 5. Multiple sets of transmission belts 106 are sleeved on the outside of the driving wheel 104 and the transmission wheel 105. The base 1 can be moved by the moving wheel 101 at the bottom. When the pure cotton pulp is to be deslagging, the driving motor 102 is first started to drive the driving wheel 104 to rotate, and the driving wheel 105 is driven to rotate under the drive of the driving belt 106, so that the rotating shaft 11 drives the filter cylinder 4 to rotate, and the pulp is introduced into the deslagging cylinder 2 through the pulp inlet pipe 3, and the deslagging is carried out by centrifugal force. Due to the large mass of the heavy residue, it will be thrown out of the outside of the filter cylinder 4 under the action of centrifugal force, and the thrown heavy residue enters the first filter chamber 7, and then is discharged from the heavy residue outlet pipe 8 under the guidance of the guide cover 6.

[0025] Furthermore, a light residue outlet pipe 201 is installed at the top of the residue removal cylinder 2 and above the filter cylinder 4, and a negative pressure collector 202 is installed on the top of the light residue outlet pipe 201. When the filter cylinder 4 is used to remove the residue from the slurry, the light residue separated has a smaller density and is collected by the light residue outlet pipe 201 in cooperation with the negative pressure collector 202.

[0026] Then, a slurry feeding bucket 301 is installed on the top of the slurry feeding pipe 3, and a rotating rod 302 is rotatably connected to the top of the inside of the slurry feeding pipe 3, and a semicircular adjustment plate 303 is symmetrically installed on the outside of the rotating rod 302. The end of the rotating rod 302 located on the outside of the slurry feeding pipe 3 is fixedly connected with an adjusting knob 304. The slurry is poured into the slurry feeding pipe 3 through the slurry feeding bucket 301, and the slurry is introduced into the slag removal cylinder 2 through the slurry feeding pipe 3. The rotating rod 302 is rotated by adjusting the knob 304, and the size of the opening inside the slurry feeding pipe 3 is controlled by using the semicircular adjustment plate 303 on the outside of the rotating rod 302, so as to adjust the flow rate of the slurry, so as to avoid the slurry flow rate being too slow or too fast to affect the slag removal effect.

[0027] Secondly, the filter cartridge 4 is designed with an inverted cone structure, and a plurality of groups of stepped protrusions 401 are fixedly connected to the inner wall of the filter cartridge 4. A plurality of groups of filter screens 402 are installed on the inner wall of the filter cartridge 4 and between the plurality of groups of stepped protrusions 401 at intervals. The slurry is introduced into the filter cartridge 4 through the slurry inlet pipe 3. When the filter cartridge 4 rotates, the slurry is filtered in multiple stages through the filter screens 402 between the plurality of groups of stepped protrusions 401. The light residue is separated from the slurry through filtering, and the slurry after residue removal passes through the filter screen 402 into the second filter chamber 9, and is finally discharged through the slurry outlet pipe 10.

[0028] Finally, the shock absorbing assembly 12 includes a connecting sleeve 1201, a connecting tube 1202, a connecting rod 1203, a shock absorbing spring 1204, a circular guide rail 1205 and a roller 1206. The connecting sleeve 1201 is fixedly installed on the outside of the rotating shaft 11 and is located inside the base 1. Four groups of connecting tubes 1202 are installed on the outside of the connecting sleeve 1201 at equal intervals. The inside of the connecting tube 1202 is slidably connected with the connecting rod 1203. The shock absorbing spring 1204 is installed on one end of the connecting rod 1203 located inside the connecting tube 1202. The circular guide rail 1205 is installed on the inside of the base 1. Internally, the roller 1206 is installed on the end of the connecting rod 1203 away from the connecting cylinder 1202 and is located inside the circular guide rail 1205. When the rotating shaft 11 rotates, a large vibration will be generated. At this time, the roller 1206 rolls in the circular guide rail 1205, which can improve the stability of the rotating shaft 11 during rotation. At the same time, the shock-absorbing spring 1204 in the connecting cylinder 1202 is used to make the connecting rod 1203 buffer the vibration by slightly expanding and contracting, thereby further improving the stability of the rotating shaft 11 during rotation, reducing the vibration impact on the entire device, and improving the effect of centrifugal slag removal.

[0029] In this embodiment, the implementation scenario is specifically as follows: when the pure cotton pulp is deslagging, the driving motor 102 is first started to drive the driving wheel 104 to rotate, and the driving wheel 105 is driven to rotate under the drive of the driving belt 106, so that the rotating shaft 11 drives the filter drum 4 to rotate, and the pulp is poured into the pulp inlet pipe 3 through the pulp inlet pipe 3, and the pulp is introduced into the filter drum 4 through the pulp inlet pipe 3. When the filter drum 4 rotates, the pulp passes through the filter screen 402 between the multiple groups of stepped protrusions 401 for multi-stage filtration, and the pulp is filtered to separate the light residue, and the pulp after deslagging passes through the filter screen 402 into the second filter chamber 9, and is finally discharged through the pulp outlet pipe 10. Due to the large mass of the heavy residue, it will be thrown out of the outside of the filter drum 4 under the action of centrifugal force, and the thrown heavy residue enters the first filter chamber 7, and then is discharged from the heavy residue outlet pipe 8 under the guidance of the guide cover 6, and the separated light residue is discharged from the filter drum 4. The slag density is relatively small, and the light slag outlet pipe 201 is used in conjunction with the negative pressure collector 202 for collection, so as to effectively separate the light and heavy slag and improve the slag removal effect. At the same time, a large vibration will be generated when the rotating shaft 11 rotates. At this time, the roller 1206 rolls in the circular guide rail 1205, which can improve the stability of the rotating shaft 11 during rotation. At the same time, the shock-absorbing spring 1204 in the connecting tube 1202 is used to make the connecting rod 1203 buffer the vibration by slightly extending and retracting, further improving the stability of the rotating shaft 11 during rotation, reducing the vibration impact on the entire device, and improving the effect of centrifugal slag removal. The entire operation process is simple and convenient. Compared with the existing slag removal device for producing pure cotton pulp, the utility model can effectively separate the light and heavy slag through design, and at the same time can improve the stability of centrifugal slag removal, reduce the vibration impact on the entire device, and improve the effect of centrifugal slag removal.
