DETAILED DESCRIPTION

[0027] The following is a further non-limiting detailed description of the technical solution of the utility model in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-5 The utility model provides a technical solution: a fiber spinning solution coloring stirring and cleaning device, comprising a base 1, two groups of mutually symmetrical brackets 2 are arranged on the upper side of the base 1, and a cylinder 3 is fixedly connected between the two groups of brackets 2 through a connecting frame, and the cylinder 3 is vertically arranged.

[0029] A cavity 4 is provided in the cylinder 3, and the cavity 4 is funnel-shaped. A plurality of feed ports 23 are provided on the upper side of the cavity 4. The feed ports 23 are connected to the raw material box through pipelines and metering pumps, so that raw materials are injected into the cavity 4 according to the ratio of the stock liquid through the metering pump for subsequent stirring.

[0030] A discharge port 5 is provided at the lower side of the cavity 4, and the discharge port 5 can be connected to the pipeline. The discharge port 5 is provided with an opening and closing device 6, and the opening and closing device 6 is an existing conventional technology, including but not limited to an electric gate valve, an electric gate, etc.

[0031] A plurality of groups of stirring blades 7 are arranged in the cavity 4 . Specifically, there are four groups of stirring blades 7 . The four groups of stirring blades 7 are evenly distributed in a circle with the axis of the cavity 4 as the center.

[0032] The maximum width of the stirring blades 7 is slightly smaller than the radius of the cavity 4. The outer edge of each group of stirring blades 7 away from the axis of the cavity 4 is consistent with the cross-sectional shape of the inner wall of the cavity 4 along the axial direction, thereby improving the stirring effect of the stock solution.

[0033] A plurality of groups of feed ports 8 are evenly arranged on the stirring blade 7. Specifically, the feed port 8 is a parallelogram inclined toward the axis of the cavity 4. The inner walls on the four sides of the feed port 8 are formed with buffer ridges 9 toward the center of the feed port 8. The buffer ridge 9 is composed of two groups of mutually symmetrical inclined surfaces. When the feed liquid passes through the feed port 8, under the structural action of the buffer ridge 9, the feed liquid can flow in a direction away from the four sides of the feed port 8, thereby improving the stirring effect.

[0034] A sealing cover 10 is provided on the side of the cylinder 3 away from the discharge port 5. The sealing cover 10 is a shell that is overall funnel-shaped. The sealing cover 10 can slide up and down in the cavity 4. The sealing cover 10 fits against the inner wall of the cavity 4. When the sealing cover 10 moves to the lower end of the cavity 4, the sealing cover 10 fits against the funnel shape on the lower side of the cavity 4.

[0035] The sealing cover 10 is sleeved on the stirring blade 7, and a sliding opening 11 is provided on the sealing cover 10 corresponding to the stirring blade 7. A groove 12 is formed on the upper side of the sealing cover 10, and a sleeve plate 13 is fixedly connected to the corresponding sliding opening 11 in the groove 12. The sleeve plate 13 is sleeved on the stirring blade 7, and a sliding opening 2 14 is provided on the sleeve plate 13. The sliding opening 11 is communicated with the sliding opening 2 14, so that the sleeve plate 13 and the sealing cover 10 form a sleeve sliding connection structure for the stirring blade 7. The sleeve plate 13 is used to lengthen the limiting length and contact area of ​​the stirring blade 7. When the stirring blade 7 is rotated under the rotation of the sealing cover 10, the sleeve plate 13 strengthens the force area and force effect of the sealing cover 10 on the stirring blade 7, thereby improving the stirring effect.

[0036] Four groups of stirring blades 7 pass through one end of the sleeve plate 13 and are fixedly connected with a ring 1 24 on the side away from the axis of the cavity 4. Four groups of stirring blades 7 are located at one end of the discharge port 5 and are fixedly connected with a ring 2 25 on the side away from the axis of the cavity 4. The rings 1 24 and 25 are both embedded in the inner wall of the cavity 4 and movably connected to the inner wall of the cavity 4. The stirring blades 7 are rotatably connected to the inner wall of the cavity 4 through the rings 1 24 and 25. When the stirring blades 7 rotate, the rings 1 24 and 25 follow the stirring blades 7 to rotate on the inner wall of the cavity 4.

[0037] The inner wall of the sliding mouth 11 is evenly provided with a number of brushes and water outlets. When the stock liquid is stirred, the sealing cover 10 is located at the top of the cavity 4. When the stock liquid is stirred and discharged from the discharge port 5, the sealing cover 10 is slid downward. While the sealing cover 10 is descending, the residual liquid on the stirring blade 7 is brushed with the brushes and the clean water sprayed from the water outlet. At the same time, the buffer ridge 9 formed by the two groups of symmetrical inclined surfaces of the feeding port 8 facilitates the brush to clean the inner wall of the feeding port 8.

[0038] Two groups of fixed circular plates 15 are fixedly connected to the sleeve plate 13 to enhance the connectivity and fastening of the sleeve plate 13 and the sealing cover 10 .

[0039] The lower set of fixed circular plates 15 are fixedly connected to the sealing cover 10 , and the upper set of fixed circular plates 15 are fixedly connected to the end of the sleeve plate 13 .

[0040] A driving device is arranged on the upper side of the sealing cover 10, and the driving device includes a transmission shaft 16. The bottom side of the groove 12 is fixedly connected to the transmission shaft 16. The transmission shaft 16 passes through the two sets of fixed circular plates 15 and is fixedly connected to a driving motor 17 after extending a certain length. A motor frame 18 is fixedly connected to the outer side of the driving motor 17.

[0041] A lifting frame 19 is fixedly connected to one side of the motor frame 18 away from the transmission shaft 16 , and two ends of the lifting frame 19 away from the motor frame 18 are sleeved on the bracket 2 .

[0042] Specifically, the length of the transmission shaft 16 is such that when the sealing cover 10 moves to the lowermost side of the cavity 4 , the lifting frame 19 will not collide with the cylinder 3 .

[0043] At the same time, the diameter and hardness of the transmission shaft 16 ensure that the torsional force generated when the driving motor 17 drives the sealing cover 10 and the stirring blade 7 to rotate and stir the stock solution through the transmission shaft 16 will not cause the transmission shaft 16 to break.

[0044] Four groups of right-angle reinforcing ribs are fixedly connected between the transmission shaft 16 and a group of fixed circular plates 15 on the upper side. The four groups of right-angle reinforcing ribs and the four groups of sleeve plates 13 are offset by 22.5° around the cavity 4 to strengthen the connectivity between the transmission shaft 16 and the sealing cover 10.

[0045] The lifting frame 19 is slidably connected to the bracket 2. A threaded hole is provided on one side of the lifting frame 19 close to the bracket 2. A screw rod 20 is screwed into the threaded hole. The screw rod 20 is axially parallel to the bracket 2 and is rotatably connected to the bracket 2. A driving motor 21 is fixedly connected to the upper side of the screw rod 20 that passes through the bracket 2. The driving motor 21 drives the screw rod 20 to rotate, thereby further making the lifting frame 19 slide up and down along the bracket 2, thereby driving the sealing cover 10 to slide up and down in the cavity 4 to clean the inner wall of the cavity 4.

[0046] A plurality of cleaning grooves 22 are arranged on the circumference of the outer wall of the side where the sealing cover 10 is in direct contact with the inner wall of the cavity 4. The cross-sectional shape of the cleaning grooves 22 along the axial direction is consistent with the cross-sectional shape of the inner wall of the cavity 4 along the axial direction. A plurality of sprayers and cleaning brushes are arranged in the cleaning grooves 22. When the sealing cover 10 rotates and descends, the sprayers and cleaning brushes in the cleaning grooves 22 make a circular rotating motion, and at the same time, the inner wall of the cavity 4 is cleaned as the sealing cover 10 moves downward.

[0047] A water supply component is arranged in the groove 12, and the water supply component includes a water storage tank, and the water storage tank is connected to a water pump through a pipeline. The output end of the water pump is connected to the water outlet and the sprinkler through the pipeline, so as to supply water for washing the cavity 4.

[0048] In this embodiment, in the initial state, the sealing cover 10 is located at the uppermost side of the cavity 4, and the opening and closing device 6 is in a closed state. At this time, the raw liquid is injected into the cavity 4 from the raw liquid tank through the metering pump.

[0049] After the stock solution is injected, the driving motor 17 is started to drive the sealing cover 10 to rotate through the transmission shaft 16, and the stirring blade 7 rotates along with the sealing cover 10, so as to evenly stir the stock solution in the cavity 4.

[0050] After the stirring is completed, the opening and closing device 6 is opened, and the raw liquid after being stirred uniformly flows out from the discharge port 5, and the raw liquid is received by an artificially placed pipeline or liquid storage tank.

[0051] After receiving is completed, drive motor 21 is started to move the lifting frame 19 downward. During the movement, drive motor 17 continues to operate, and the sealing cover 10 continues to rotate and moves downward along the axis of the cavity 4. During the rotation and movement of the sealing cover 10, the sliding mouth 11 brushes the stirring blade 7 downward, and at the same time, the cleaning brush in the cleaning groove 22 brushes the inner wall of the cavity 4.

[0052] When the sealing cover 10 moves to the lowermost side of the cavity 4, the driving motor 2 21 is operated in reverse, so that the sealing cover 10 rotates upward in the reverse direction and resets to the initial state, and the operation of the driving motor 1 17 and the driving motor 2 21 is stopped to complete the cleaning of the cavity 4 and the stirring blade 7.
