Description

TECHNICAL FIELD

[0001] The present application relates to the field of textile wastewater filtration equipment, in particular to a textile wastewater filtration and purification equipment and method. BACKGROUND

[0002] Textile wastewater usually contains various pollutants such as organic matter, pigments, dyes, grease, heavy metals, etc., so it needs to go through a series of treatment steps for filtration and purification. The conventional treatment method of textile wastewater can be roughly divided into five kinds, which are physical treatment, chemical treatment, biological treatment, activated carbon adsorption and membrane separation technology.

[0003] The five methods of textile wastewater each have advantages and disadvantages. Among them, the physical treatment method has screen filter, sedimentation, clarification and flotation, etc. In the screen filter, by rotating the appropriate screen material and pore size, the particles of corresponding size and characteristics in the textile wastewater can be intercepted, thereby removing part of the impurities in the wastewater. However, the dyes in the wastewater are usually organic substances, and their color and chemical properties make it difficult to remove them by traditional physical filtration methods. Therefore, screen filter alone cannot effectively remove dyes, and methods such as activated carbon adsorption, biodegradation or oxidation treatment are needed to remove organic substances. However, activated carbon material has the disadvantages of difficult maintenance and high regeneration cost, and biodegradation and oxidation treatment also have high cost and long time-consuming, so it is necessary to design a new type of physical pollution removal filtration and purification equipment and method to remove dye impurities in textile wastewater.

DETAILED DESCRIPTION

[0038] In order to further understand the features, technical means and specific purposes and functions achieved by the present application, the present application is described in further detail below in combination with the drawings and specific embodiments.

[0039] Reference Figures 1 to 14The textile wastewater filtering and purifying device shown comprises a mechanical hand 1, a decontamination pool 2 fixed in a horizontal state and with an open top, and a jacking cylinder 3 arranged on the decontamination pool 2, the decontamination pool 2 is provided with a liquid inlet 4 and a liquid outlet 5, the mechanical hand 1 clamps a replaceable decontamination assembly 6, the decontamination assembly 6 comprises a main plate 7 in a vertical state and capable of being clamped by the mechanical hand 1, two groups of symmetrical side plate sets arranged on both sides of the main plate 7, and eight decontamination fiber plates 8, each group of side plate sets comprises an inner plate 9 close to the main plate 7 and an outer plate 10 away from the main plate 7, the main plate 7 is fixedly connected with four evenly distributed limiting horizontal shafts 11 in sliding connection with the inner plate 9 and the outer plate 10, one of the decontamination fiber plates 8 is fixedly connected to both sides of the main plate 7 and each inner plate 9, one of the decontamination fiber plates 8 is fixedly connected to the end of each outer plate 10 close to the main plate 7, the main plate 7 and the two inner plates 9 are elastically connected, one side of the main plate 7 and the two inner plates 9 is provided with a first limiting piece for synchronously and equidistantly approaching and moving away from the main plate 7, the side of each side plate set away from the first limiting piece is further provided with a second limiting piece connected with the main plate 7, the second limiting piece is used for cooperating with the first limiting piece to synchronously approach and move away from the main plate 7, while keeping the distance between the corresponding main plate 7 and the corresponding outer plate 10 and the inner plate 9 consistent, and the jacking cylinder 3 is used for jacking the corresponding side outer plate 10 towards the main plate 7.

[0040] The liquid inlet 4 is arranged on the side wall of one end of the fixed jacking cylinder 3 of the decontamination tank 2, and the liquid outlet 5 is arranged on the bottom of the decontamination tank 2. The decontamination tank 2 has a length direction and a width direction. The two outer plates 10, the two inner plates 9, the main plate 7 and the eight sewage absorbing fiber plates 8 are arranged in the length direction of the decontamination tank 2. The first limiting member and the second limiting member are located on both sides of the length direction of the decontamination tank 2. When the decontamination assembly 6 is used, the mechanical arm 1 (the mechanical arm 1 is the output end of an industrial robot, and only the mechanical arm 1 is shown in the figure, and the base and the mechanical arm part of the industrial robot are not shown) clamps the top of the main plate 7 and lifts the main plate 7 into the decontamination tank 2. The two inner plates 9 and the two outer plates 10 are lifted into the decontamination tank 2 due to the limiting of the four limiting horizontal shafts 11. Under the action of the elastic force between the main plate 7 and the two inner plates 9 and the elastic force between the two inner plates 9 and the two outer plates 10, and in cooperation with the limiting of the first limiting member and the second limiting member, the two inner plates 9 and the two outer plates 10 are elastically pushed away to the state of being farthest away from the main plate 7 (the two ends of the limiting horizontal shaft 11 can limit the two outer plates 10 to prevent the two outer plates 10 from coming out). After the decontamination assembly 6 is suspended into the decontamination tank 2, the liquid outlet 5 of the decontamination tank 2 is closed, and the liquid inlet 4 starts to flow into the decontamination tank 2. After the decontamination tank 2 is filled with appropriate textile sewage, the liquid inlet 4 is also closed and no longer injects textile sewage. At the same time, the output end of the jacking cylinder 3 starts to repeatedly stretch and contract. After the output end of the jacking cylinder 3 stretches out, the output end of the jacking cylinder 3 will push the corresponding outer plate 10 towards the main plate 7, so that the corresponding outer plate 10 and the inner plate 9 on the same side are synchronized to approach the main plate 7. The main plate 7 remains stationary under the clamping of the mechanical arm 1. Under the joint action of the first limiting member and the second limiting member, the two inner plates 9 and the two outer plates 10 are synchronized to approach the main plate 7 (when the two inner plates 9 and the two outer plates 10 are synchronized to approach the main plate 7 to the limit distance, the eight sewage absorbing fiber plates 8 will not collide with each other). When the output end of the jacking cylinder 3 retracts, the two inner plates 9 and the two outer plates 10 automatically return to the original position under the action of the elastic force. After the output shaft of the jacking cylinder 3 repeatedly moves in this way, the two inner plates 9 and the two outer plates 10 fully agitate the sewage in the decontamination tank 2, accelerate the absorption of dye impurities in the textile sewage by the eight sewage absorbing fiber plates 8, and open the liquid outlet 5 to discharge the liquid in the decontamination tank 2. At the same time, the mechanical arm 1 lifts the decontamination assembly 6 away from the decontamination tank 2. The decontamination tank 2 is also provided with a residual water receiving tank (not shown in the figure) and a second cylinder (not shown in the figure) on the side. After the decontamination assembly 6 is lifted away from the decontamination tank 2, it is moved to above the residual water receiving tank. Then the output end of the second cylinder stretches out and pushes the corresponding outer plate 10 towards the main plate 7 until the two sewage absorbing fiber plates 8 on the side facing each other of each outer plate 10 and the corresponding inner plate 9 and the side facing each other of each inner plate 9 and the main plate 7 are squeezed and contracted to each other. In this way, part of the dye impurities and waste water adsorbed on the sewage absorbing fiber plate 8 are squeezed out of the sewage absorbing fiber plate 8, so as to preliminarily remove part of the dye impurities on the sewage absorbing fiber plate 8.In order to prolong the service life of the eight dirt-absorbing fiber plates 8 as much as possible, when the dirt-absorbing capacity of the eight dirt-absorbing fiber plates 8 is affected by excessive accumulation of dye impurities, another set of dirt-removing assembly 6 can be used by the mechanical hand 1.

[0041] In order to make the two inner plates 9 synchronously and equidistantly approach and move away from the main plate 7 by the limiting of the first limiting member, the following features are specifically provided:

[0042] The first limiting member includes a first rhombic plate 12 and two first connecting rods 13 hingedly arranged at both ends of the first rhombic plate 12, the main plate 7 has a T-shaped structure in cross section, the two dirt-absorbing fiber plates 8 are symmetrically and fixedly connected to the lower ends of the main plate 7 on both sides, the main plate 7 has a first protruding column 14 formed in the middle of the corresponding side wall, the corresponding side wall of one of the inner plates 9 has a second protruding column 15 formed in the upper part, the corresponding side wall of the other inner plate 9 has a third protruding column 16 formed in the lower part, the two first connecting rods 13 are hingedly arranged at the second protruding column 15 and the third protruding column 16 respectively at one end away from the first rhombic plate 12, and the other ends of the two first connecting rods 13 are hingedly arranged at the two long ends of the first rhombic plate 12, and the two first connecting rods 13 are centrally symmetric about the axis of the first protruding column 14.

[0043] The disassembled connection state between the first rhombic plate 12 and the two first connecting rods 13 and the main plate 7 and the two inner plates 9 is shown in Figure 10 and Figure 11 The vertical distance between the second protruding column 15 and the third protruding column 16 and the first protruding column 14 is equal, and the second protruding column 15 and the third protruding column 16 are located above and below the first protruding column 14 respectively. Since the two inner plates 9 can only translate along the axis of the limiting horizontal shaft 11 under the limiting of the four limiting horizontal shafts 11, when one of the inner plates 9 approaches or moves away from the main plate 7, the corresponding first connecting rod 13 is driven to rotate and move, thereby driving the first rhombic plate 12 to rotate on the first protruding column 14, and further driving the other first connecting rod 13 to drive the corresponding inner plate 9 to approach or move away from the main plate 7. Since the two first connecting rods 13 are always centrally symmetric about the axis of the first protruding column 14, the two inner plates 9 are always synchronously and equidistantly approaching or moving away from the main plate 7.

[0044] In order to make the corresponding inner plate 9 and outer plate 10 synchronously approach and move away from the main plate 7 by the cooperation of the first limiting member and the second limiting member, and the distance between the main plate 7 and the outer plate 10 and the inner plate 9 is always equal, the following features are specifically provided:

[0045] Each of the second limiting members comprises a second rhombic plate 17 and two second connecting rods 18 hingedly arranged at two ends of the second rhombic plate 17, a fourth protrusion 19 is formed in the middle of the side wall of the inner plate 9 away from the second protrusion 15, the second rhombic plate 17 is hingedly arranged on the fourth protrusion 19, and the two second connecting rods 18 are centrally symmetric about the axis of the fourth protrusion 19, a fifth protrusion 20 and a sixth protrusion 21 are respectively formed on the upper and lower side walls of the main plate 7 away from the first protrusion 14, a seventh protrusion 22 is formed on the lower part of the corresponding side wall of one of the outer plates 10, and an eighth protrusion 23 is formed on the upper part of the corresponding side wall of the other outer plate 10, in the second limiting member close to the seventh protrusion 22, the upper end of the second connecting rod 18 close to the main plate 7 is hingedly arranged on the fifth protrusion 20, the other end of the second connecting rod 18 is hingedly arranged below the corresponding side second rhombic plate 17, the upper end of the other second connecting rod 18 is hingedly arranged on the upper long end of the second rhombic plate 17, and the lower end of the second connecting rod 18 is hingedly arranged on the seventh protrusion 22; in the second limiting member close to the eighth protrusion 23, the upper end of the second connecting rod 18 close to the main plate 7 is hingedly arranged on the sixth protrusion 21, the other end of the second connecting rod 18 is hingedly arranged on the upper long end of the corresponding side second rhombic plate 17, the lower end of the other second connecting rod 18 is hingedly arranged on the lower long end of the second rhombic plate 17, and the upper end of the second connecting rod 18 is hingedly arranged on the eighth protrusion 23.

[0046] The disassembled connection state between the two second rhombic plates 17 and the four second connecting rods 18 and the main plate 7, the two inner plates 9 and the two outer plates 10 is shown in Figure 12 and Figure 13 Since the main plate 7 cannot move under the limitation of the mechanical hand 1, when the corresponding outer plate 10 is pushed by the output end of the jacking cylinder 3 to approach the main plate 7, the corresponding second connecting rod 18 is rotated and moved by the outer plate 10, thereby rotating the corresponding second rhombic plate 17 on the fourth protrusion 19, and the other second connecting rod 18 is hingedly arranged on the main plate 7 and can only rotate, so that the two second connecting rods 18 rotate and move and make the second rhombic plate 17 rotate, thereby driving the corresponding inner plate 9 to approach the main plate 7 synchronously, and since the two second connecting rods 18 are always centrally symmetric about the axis of the fourth protrusion 19, the distance between the inner plate 9 and the main plate 7 and the distance between the inner plate 9 and the outer plate 10 are always equal, so that when the sizes of the several pollution-absorbing fiber plates 8 are consistent, the several adjacent pollution-absorbing fiber plates 8 can be simultaneously contacted and separated, thereby the moving distance of the output end of the jacking cylinder 3 can be controlled to control that the several adjacent pollution-absorbing fiber plates 8 in the pollution-removing tank 2 are always not pressed against each other, thereby ensuring that the dye impurities absorbed in the pollution-absorbing fiber plate 8 cannot be squeezed back into the pollution-removing tank 2.

[0047] In order to connect the main plate 7, the two inner plates 9, the two outer plates 10 and the four limiting horizontal shafts 11, the following features are specifically provided:

[0048] The four corners of the main plate 7 are provided with cylindrical transverse grooves 24, the middle part of the limiting transverse shaft 11 is fixedly arranged in the cylindrical transverse groove 24, and the four limiting transverse shafts 11 are respectively connected to the four corners of the inner plate 9 and the outer plate 10 in sliding mode. Four springs 25 are coaxially arranged on each limiting transverse shaft 11. The opposite ends of the two inner springs 25 are respectively abutted on the two sides of the main plate 7. The opposite ends of the two inner springs 25 are respectively abutted on the opposite ends of the two inner plates 9. The opposite ends of the two outer springs 25 are respectively abutted on the opposite ends of the two inner plates 9. The opposite ends of the two outer springs 25 are respectively abutted on the opposite ends of the two outer plates 10. The two ends of each limiting transverse shaft 11 are coaxially fixedly connected with two end limiting caps 26 for preventing the outer plate 10 from being separated.

[0049] The limiting transverse shaft 11 is connected to the two inner plates 9 and the two outer plates 10 in sliding mode, thereby ensuring that the two inner plates 9 and the two outer plates 10 can only translate axially along the limiting transverse shaft 11. The limiting of the four springs 25 on each limiting transverse shaft 11 ensures that there is always a certain elastic force between the main plate 7 and the inner plate 9 and between the inner plate 9 and the outer plate 10, thereby ensuring that the two inner plates 9 and the two outer plates 10 can move away from the main plate 7 synchronously after the output end of the jacking cylinder 3 is retracted.

[0050] In order to reinforce the connection between the limiting transverse shaft 11, the main plate 7, the two inner plates 9 and the two outer plates 10, the following features are provided:

[0051] Each spring 25 is coaxially provided with a limiting sleeve member. Each set of limiting sleeve members includes two symmetrically arranged end sleeves 27 and a cylindrical member coaxially and slidingly arranged in the two end sleeves 27. The cylindrical member includes a limiting cylinder and a limiting circular cap 28 coaxially and fixedly connected to one end of the limiting cylinder. The limiting cylinder includes a body 29 close to one end of the limiting circular cap 28 and a stepped portion 30 formed at the end of the body 29 away from the limiting circular cap 28. The opposite ends of the two end sleeves 27 are formed with stepped neckings 31. The limiting circular cap 28 and the stepped portion 30 are coaxially and slidingly arranged in the two end sleeves. The body 29 is coaxially and slidingly arranged in the two stepped neckings 31. The limiting transverse shaft 11 is coaxially and slidingly arranged in the cylindrical member. The opposite ends of the two end sleeves 27 located between the main plate 7 and the inner plate 9 are fixedly connected to the main plate 7 and the inner plate 9. The opposite ends of the two end sleeves 27 located between the inner plate 9 and the outer plate 10 are fixedly connected to the inner plate 9 and the outer plate 10. The spring 25 is coaxially arranged outside the two end sleeves 27. The middle part of the limiting transverse shaft 11 is formed with an annular flange 32 fixedly connected to the cylindrical transverse groove 24.

[0052] After setting the limiting cylinder, the limiting round cap 28 and the two end sleeves 27, the main plate 7 and the inner plate 9, and the inner plate 9 and the outer plate 10 can also be connected through the limiting cylinder, the limiting round cap 28 and the two end sleeves 27, and the inner plate 9 and the outer plate 10 can only translate axially along the limiting cylinder, so that the limiting cross shaft 11 coaxially arranged in the plurality of limiting cylinders bears the gravity of the two inner plates 9 and the two outer plates 10 together, thereby reducing the bearing burden of the limiting cross shaft 11, and ensuring that the two inner plates 9 and the two outer plates 10 can be more stably arranged on both sides of the main plate 7. The annular flange 32 is in interference fit with the cylindrical through slot, and two symmetrical hole elastic retaining rings (not shown in the figure) are embedded in the cylindrical through slot on both sides of the annular flange 32, thereby further axially limiting the limiting cross shaft 11. In this way, the fixed connection of the limiting cross shaft 11 and the main plate 7 can be ensured, and the two cylinder pieces can also translate within a certain range in the cylindrical through slot.

[0053] In order to ensure that all the dirt-absorbing fiber plates 8 can be compressed after the two inner plates 9 and the two outer plates 10 are synchronously close to the main plate 7, the following features are specifically provided:

[0054] The cross section of the two outer plates 10 is in inverted L-shaped structure, the dirt-absorbing fiber plate 8 is fixedly arranged at one end of the outer plate 10 close to the main plate 7, and the lower end of each dirt-absorbing fiber plate 8 is formed with two avoiding notches 33 for avoiding the two springs 25 below.
