Description

Technical Field

[0001] The utility model relates to the technical field of mercerizing machines, in particular to an alkali liquid impurity removing device of a mercerizing machine. Background Art

[0002] Mercerizing machine is a device that treats cotton yarn and cotton fabric with concentrated caustic soda solution under certain tension conditions and washes with water to remove alkali. In knitting production, it is mainly used for processing weft-knitted tubular cotton knitted grey fabrics. The mercerizing machine is mainly composed of a cloth feeding rack, an alkali dipping tank, a ventilation device, a width expansion device, a flushing device and a flat washing tank.

[0003] In the existing mercerizing machine equipment, some impurities such as textile fibers will remain in the used alkali solution, but it is difficult to remove impurities and recycle the used alkali solution, resulting in waste of alkali solution and increased production costs.

[0004] Therefore, an alkali solution impurity removal device for a mercerizing machine is proposed to solve the above problems. Utility Model Content

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: the alkali liquid impurity removal device of the mercerizing machine includes a cylinder, a rotating device and a filtering device, the rotating device is fixedly connected to the top surface of the cylinder and penetrates into the inside of the cylinder, the filtering device is detachably connected to the inner circumferential wall of the cylinder in a circular array, the rotating device drives the liquid in the cylinder to flow, and brings the impurities in the cylinder into the filtering device through the liquid flow for collection and filtration, the rotating device includes a motor, a transmission rod, a rotating shaft and a spiral annular blade, the motor is fixedly connected to the top surface of the cylinder, the transmission rod is transmission-connected to the bottom of the motor and penetrates into the cylinder to the inside of the cylinder, the rotating shaft is fixed Connected to the bottom end of the transmission rod, the blades are fixedly connected to the outer peripheral wall of the rotating shaft. When the rotating shaft rotates, the blades are driven to rotate clockwise, and the liquid in the cylinder body generates a clockwise vortex. The filtering device includes an annular fixing ring, a net bag and a plurality of clips. One end of the fixing ring is fixedly connected to a cylindrical fixing part, and the fixing part is detachably connected to the inner peripheral wall of the cylinder body. The clip is elastic and one end of which is a U-shaped opening. The clip is detachably connected to the outer peripheral wall of the fixing ring. The opening cross-section of the net bag is circular and the opening end is fixedly connected to the end of the clip away from the fixing ring. Impurities collected by the net bag cannot flow out from the inside.

[0007] By adopting the above technical scheme, the rotating device can drive the generation of eddy currents in the cylinder and drive the liquid to move in a certain direction, and bring impurities into the filtering device through the liquid for collection and filtration, thereby reducing the impurity content in the alkali solution. The motor drives the transmission rod to rotate and causes the spiral annular blades on the rotating shaft to rotate clockwise. When the spiral annular blades rotate, they twist the liquid together and push it outward, so that the liquid can flow toward the inner wall of the cylinder instead of concentrating in the center, and generate a clockwise eddy current to drive the impurities in the liquid to flow, so that when the net bag opening is opened, the net bag can be detachably connected to the fixed ring, and at the same time, the net bag and the fixed ring are fixed to the inner wall of the cylinder to filter and collect impurities brought by the liquid flow.

[0008] The utility model is further configured as follows: the blade spiral angle is between 30 degrees and 45 degrees.

[0009] By adopting the above technical solution, the vortex flow velocity formed by the rotation of the blades is increased, the flow is more stable, and the collection and filtration efficiency is improved.

[0010] The utility model is further configured such that: the collecting direction of the opening of the net bag is opposite to the direction of liquid flow.

[0011] By adopting the above technical solution, the liquid flows toward the opening of the net bag, and the impurities that flow in cannot flow out through the water flow, thereby effectively collecting the impurities in the liquid.

[0012] The utility model is further configured as follows: the mesh size of the net bag is between 1 square millimeter and 2 square millimeters.

[0013] By adopting the above technical solution, the impurities collected in the net bag will not flow out of the net bag.

[0014] The utility model is further configured as follows: the fixing ring and the net bag are both made of anti-corrosion materials.

[0015] By adopting the above technical solution, the liquid will not corrode the surfaces of the fixing ring and the net bag when flowing through them, thus preventing the fixing ring and the net bag from being damaged and affecting the work.

[0016] In summary, the utility model has the following beneficial effects: the rotation of the spiral blades of the rotating device drives the liquid in the cylinder to generate a clockwise vortex, thereby driving the impurities in the liquid to move in the clockwise direction. When the spiral blades rotate, the liquid will not gather in the middle but diffuse outward toward the inner wall of the cylinder. At the same time, the inner wall of the cylinder is detachably connected to a filter device. The opening of the net bag of the filter device is opposite to the direction of liquid flow, which can effectively collect impurities. The buckle of the filter device is elastic and the opening is a U-shaped opening, so that the opening end of the buckle can be detachably connected to the outer peripheral wall of the fixed ring, and the other end of the buckle is fixedly connected to the net bag, so that when the opening of the net bag is opened, it can be fixed on the fixed ring for filtering. Both the filter device and the rotating device are corrosion-resistant to prevent corrosion by alkali solution from affecting their functions. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] Example:

[0026] like Figure 1 to Figure 2As shown, the alkali liquid impurity removing device of the mercerizing machine includes a cylinder 11, a rotating device and a filtering device. The motor 12 fixed by bolts on the top surface of the cylinder 11 drives the transmission rod 13 to rotate, thereby driving the rotating shaft 14 in the cylinder 11 to drive the spiral blade 15 to rotate clockwise, and the liquid diffuses outward toward the inner wall of the cylinder 11, and generates an eddy current flowing in the clockwise direction to drive the impurities in the liquid to flow. The fixing piece threadedly connected to the inner circumferential wall of the cylinder 11 fixes the fixing ring 16 and the net bag 17 on the inner circumferential wall of the cylinder 11. The eddy current brings the wool and other impurities in the cylinder 11 into the net bag 17, and the net bag 17 collects the wool and other impurities. The net bag 17 is buckled and connected to the fixing ring 16 by the buckle 18. When a certain amount of wool impurities are collected, the net bag 17 on the fixing ring 16 is removed, and the internal impurities are cleaned and then buckled again on the outer circumferential wall of the fixing ring 16. It can be repeatedly recycled to clean the impurities in the alkali liquid.

[0027] like Figure 2 As shown, the cylinder 11 is a cylindrical cylinder 11, which is made of Hastelloy stainless steel material and has good corrosion resistance. The top surface is provided with a feed inlet for liquid inlet, and the bottom surface is provided with a discharge outlet for liquid discharge. The rotating device includes a motor 12, a transmission rod 13, a rotating shaft 14 and a spiral annular blade 15, wherein the motor 12 is a DC motor 12, and the transmission rod 13, the rotating shaft 14 and the blade 15 are all Hastelloy stainless steel. oy stainless steel material, the transmission rod 13 passes through the top surface of the cylinder 11 and extends into the inside of the cylinder 11, the rotating shaft 14 is a cylindrical shaft body and is welded to the bottom end of the transmission rod 13 and rotates with the transmission rod 13, the blade 15 is spiral ring-shaped and is formed integrally with the rotating shaft 14, the number of spiral turns of the spiral blade 15 is 4, and the spiral angle of the blade 15 is between 30 degrees and 45 degrees. When the motor 12 rotates, the transmission rod 13 rotates clockwise and drives the rotating shaft 14 below to move together, and the rotating shaft 14 then drives the spiral ring blade 15 to rotate, so that the liquid is twisted together and diffuses outward from the inner circumferential wall of the cylinder 11, forming a vortex flowing to the outer circle of the cylinder 11.

[0028] The transmission rod 13, the rotating shaft 14 and the blades 15 of the rotating device are made of Hastelloy stainless steel, so that it is not easy to be corroded in the alkali solution and affect the normal operation. The motor 12 provides power to drive the transmission rod 13, the rotating shaft 14 and the blades 15 to rotate clockwise, so that when the blades 15 rotate, a clockwise vortex is formed in the liquid. The angle of the spiral blades 15 is between 30 degrees and 45 degrees, so that the velocity of the formed vortex is increased and the flow is more stable, thereby improving the collection and filtration efficiency. Since the liquid can flow along the inner wall of the cylinder 11 instead of being concentrated in the center of the cylinder 11, the clockwise vortex drives the impurities in the liquid to flow clockwise to the filter device for collection.

[0029] like Figures 2 to 5As shown, the filter device is distributed in a circular array in the cylinder 11 and is detachably connected to the inner wall of the cylinder 11. The filter device includes four circular fixing rings 16, four net bags 17 and buckles 18. Each fixing ring 16 is detachably connected with 32 buckles 18, and the fixing ring 16, the net bag 17 and the buckle 18 are Haste ll oy stainless steel material, one end of the fixing ring 16 is integrally formed with a cylindrical fixing part, the inner diameter of the fixing part is 6 cm and the length is 15 cm, the outer peripheral wall of the fixing part is provided with a thread, the thread depth is 8 cm, and it is threadedly connected with the threaded hole on the inner peripheral wall of the cylinder 11, so that the fixing ring 16 can be fixed on the inner peripheral wall of the cylinder 11, the opening of the buckle 18 is a U-shaped opening and is elastic, the buckle 18 is buckled on the outer peripheral wall of the fixing ring 16 in a circular array, and the inner wall of the U-shaped mouth of the buckle 18 is in contact with the outer peripheral wall of the fixing ring 16, and the other end of the buckle 18 is integrally formed with a net bag 17, the opening direction of the net bag 17 is opposite to the direction of liquid flow, the cross-section of the net bag 17 is circular when it is opened, and the inner diameter is equal to the inner diameter of the fixing ring 16, the net bag 17 is fixed to the fixing ring 16 by the buckle 18, and the mesh size of the net bag 17 is between 1 square millimeter and 2 square millimeters.

[0030] The fixing ring 16, the net bag 17 and the buckle are made of Hastelloy stainless steel to have a certain supporting strength, and will not be corroded in an alkaline environment to affect the filtration. The fixing ring 16 is threadedly connected to the inner wall of the cylinder 11 through an integrally formed cylindrical fixing piece. The buckle 18 is elastic and can be snapped onto the outer peripheral wall of the fixing ring 16 after the U-shaped opening of the buckle 18 is opened. After the snap connection, the inner peripheral wall of the U-shaped opening of the buckle 18 fits with the outer peripheral wall of the fixing ring 16 to ensure the stability of the connection. 32 buckles 18 are snap-connected to the bottom surface of the fixing ring 16 along the annular surface of the fixing ring 16 to form a circular cross-section. The end of the buckle 18 away from the fixing ring 16 is The integrally formed net bag 17 can filter impurities brought by the flow of liquid. The opening of the net bag 17 is opposite to the flow direction of the liquid, so that the flowing liquid can flow smoothly into the net bag 17 to collect the impurities. When the net bag 17 is opened, a circular opening is formed, which is fixed to the fixing ring 16 through the snap fastener 18 integrally formed with it, so that it is fixed to the inner wall of the cylinder 11 for filtering and collecting. The mesh size of the net bag 17 is between 1 square millimeter and 2 square millimeters, so that the liquid can flow freely in the net bag 17 while the collected wool impurities cannot flow out of the net bag 17, thereby effectively filtering.

[0031] like Figure 1 to Figure 2As shown, when the alkali solution is discharged into the cylinder 11 from the feed port, the motor 12 is started to drive the transmission rod 13, the rotating shaft 14 and the blades 15 to rotate clockwise. The spiral blades 15 disturb the liquid and make the liquid subject to the effect of centrifugal force. The liquid flows along the contour line and the pitch direction of the spiral blades 15. Since the pitch of the spiral blades 15 is constantly changing, the vortex is constantly rotating and expanding, which further strengthens the movement of the vortex and causes the liquid to be continuously withdrawn, thereby forming an outwardly diffused vortex. The vortex drives the wool and other impurities in the liquid to flow in a clockwise direction. At the same time, a net bag 17 is buckled on the fixing ring 16 threadedly connected to the inner wall. The net bag 17 collects impurities brought by the liquid to reduce the impurities in the liquid in the cylinder 11. The fixing ring 16 is threadedly connected to the inner wall through an integrally formed cylindrical fixing part, which can be easily disassembled, replaced and maintained. The opening of the net bag 17 is a circular cross-section when it is stretched, and the open end of the net bag 17 is connected to the bottom end of the snap member 18. The snap member 18 is elastic and has a U-shaped opening, which can be easily stretched and tightly buckled on the fixing ring 16 after the opening. There are 32 snap members 18 that are buckled along the annular surface of the fixing ring 16, so that the net bag 17 integrally formed at the bottom end of the snap member 18 can be firmly fixed on the fixing ring 16 for filtration and collection. Through the cooperation of the rotating device and the filtering device, the wool impurities in the alkali solution can be effectively reduced. The used alkali solution is discharged from the discharge port, which can be effectively removed and recycled, thereby reducing the cost of production and use of the mercerizing machine.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
