Description

Technical Field

[0001] The present invention relates to the technical field of fabric printing and dyeing, and specifically to a printing and dyeing equipment with waste gas recovery function. Background Art

[0003] In the production process of textile printing and dyeing, dipping and boiling are required. During this process, waste gas is emitted. The waste gas contains a large amount of volatile organic compounds, which will pollute the atmosphere and environment and endanger human health. In addition, the waste gas also contains dyes, auxiliaries, lubricating oil, fiber particles, etc., with dozens of components. Most of these components exist in the form of molecular gaseous substances or in the form of tiny liquid droplets forming aerosols in the air. These are all one of the sources of photochemical pollution in the air;

[0004] In the prior art, the methods for treating the waste gas generated during the boiling process are activated carbon adsorption method and combustion method. The combustion method can only reduce the harm to the environment, and the products after combustion still have great harm when discharged into the atmosphere. In the existing activated carbon adsorption method, the amount of activated carbon is generally not controllable. Excessive use of activated carbon will cause waste of activated carbon, and insufficient treatment effect will be obtained with too little amount. Using an electric control method to control the amount, the electric control device will be frequently damaged due to the high temperature of the waste gas. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art, a printing and dyeing equipment with waste gas recovery function is proposed by the present invention. In the condenser, the gas with a higher boiling point in the waste gas is liquefied, and the liquefied liquid enters the waste gas treatment pipe to impact the water inlet plug plate, so as to change the amount of activated carbon by changing the opening size.

[0006] The technical solution adopted by the present invention to solve its technical problems is: a printing and dyeing equipment with waste gas recovery function, including a printing and dyeing pool body. An electric heating tube is fixedly installed inside the printing and dyeing pool body, and a traction roller is fixedly installed on the side of the pool body of the printing and dyeing pool body. The upper end of the printing and dyeing pool body is fixedly welded with a top plate through a column, and a hydraulic cylinder is fixedly installed at the lower end of the top plate. The piston end of the hydraulic cylinder is provided with a waste gas recovery mechanism;

[0007] The waste gas recovery mechanism includes a pool body cover plate. Two groups of symmetrically arranged intake elbow pipes are welded and communicated at the upper end of the pool body cover plate. The end of the intake elbow pipe is welded and communicated with a condenser. The lower end of the condenser is welded and communicated with a waste gas treatment pipe. An activated carbon water inlet pipe is welded and communicated on the side of the waste gas treatment pipe. A water inlet plug plate is slidably connected inside the waste gas treatment pipe, and a tension spring is installed on the upper surface of the water inlet plug plate. The upper end of the tension spring is fixedly connected with the inner wall of the waste gas treatment pipe.

[0008] Preferably, five groups of electric heating tubes are arranged at equal intervals, and the electric heating tubes are connected in parallel. Four fabric pressing rods are also fixedly welded inside the printing and dyeing pool body, and the fabric pressing rods are located below the electric heating tubes.

[0009] Preferably, a fabric inlet groove is formed in the lower part of the pool cover plate, and the fabric inlet grooves are symmetrically arranged on the side walls of the pool cover plate.

[0010] Preferably, an arc-shaped groove is formed at the fabric outlet of the printing and dyeing pool body, and the traction roller is installed above the arc-shaped groove. The distance between the surface of the traction roller and the surface of the arc-shaped groove is 0.3 mm.

[0011] Preferably, the side wall of the condensate member is of a double-layer structure, and condensate water pipe joints are welded and communicated on both sides of the condensate member. A frustum-shaped diversion part is integrally formed at the lower part of the condensate member.

[0012] Preferably, the angle between the waste gas treatment pipe and the vertical plane is 30°. Two sliding grooves are formed in the waste gas treatment pipe, and two sliding blocks are integrally formed on one side of the water inlet plug plate. The water inlet plug plate is slidably connected to the inside of the waste gas treatment pipe through the cooperation of the sliding groove and the sliding block.

[0013] Preferably, the upper end of the tension spring is fixedly welded to the top of the sliding groove, and the lower end of the tension spring is fixedly welded to the sliding block on the side of the water inlet plug plate.

[0014] Preferably, a neutralization box is arranged at the lower part of the waste gas treatment pipe, and a liquid outlet is formed in the side wall of the neutralization box. The lower end of the waste gas treatment pipe is inserted into the liquid in the neutralization box.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. The present invention treats waste gas through a waste gas recovery mechanism that can be lifted. The waste gas enters the condensate member through the intake elbow for condensation. Gases with higher boiling points will be condensed into liquids by the condensate water in the condensate member, and the liquids will flow along the side wall of the waste gas treatment pipe, thereby impacting the water inlet plug plate. The position of the water inlet plug plate will change due to the magnitude of the impact force, thereby changing the size of the communication surface between the activated carbon water inlet pipe and the waste gas treatment, controlling the liquid flow rate, having a low failure rate, and avoiding unnecessary waste of activated carbon.

[0017] 2. The present invention is designed with fabric pressing rods. The fabric passes through the lower ends of the fabric pressing rods. The fabric pressing rods can completely press the fabric in the liquid for printing and dyeing, and it will not float on the liquid surface due to the traction force of the traction roller and its own buoyancy, improving the printing and dyeing effect.

[0018] 3. The present invention drives the fabric to be conveyed forward by the slow rotation of the traction roller, thereby continuously dyeing and printing the fabric. Moreover, the liquid in the fabric will be extruded by the traction roller and the arc-shaped groove, and finally flow back into the dyeing pool body along the arc-shaped groove, reducing the waste of dyeing liquid and improving the profitability of the enterprise.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0035] The following is further described in conjunction with the attached Figures 1-6 This application will be further described in detail:

[0036] The embodiment of this application discloses a printing and dyeing equipment with an exhaust gas recovery function. Refer to Figure 1 And Figure 2 , including a printing and dyeing pool body 1, the side of the printing and dyeing pool body 1 has a liquid inlet 107, a traction roller 102 is fixedly installed on the side of the pool body of the printing and dyeing pool body 1, an electric heating tube 101 is fixedly installed inside the printing and dyeing pool body 1, five groups of electric heating tubes 101 are arranged at equal intervals, and the electric heating tubes 101 are connected in parallel. The electric heating tube 101 can increase the temperature of the liquid in the printing and dyeing pool body 1, thereby increasing the rate at which the dye liquor enters the fabric;

[0037] Refer to Figure 2, inside the dyeing tank body 1, four groups of fabric pressing rods 105 are also welded and fixed. The fabric pressing rods 105 are located below the electric heating tubes 101. The fabric passes through the lower ends of the fabric pressing rods 105. The fabric pressing rods 105 can completely press the fabric in the liquid for dyeing, and it will not float on the liquid surface due to the traction force of the traction rollers 102 and its own buoyancy;

[0038] Refer to Figure 2 , at the fabric outlet of the dyeing tank body 1, an arc-shaped groove 106 is provided, and the traction roller 102 is installed above the arc-shaped groove 106. The distance between the surface of the traction roller 102 and the surface of the arc-shaped groove 106 is 0.3 mm. The fabric passes through between the traction roller 102 and the arc-shaped groove 106. The traction roller 102 rotates slowly to drive the fabric forward, so as to continuously dye the fabric, and the liquid in the fabric will be squeezed out by the traction roller 102 and the arc-shaped groove 106, and finally flow back into the dyeing tank body 1 along the arc-shaped groove 106;

[0039] Refer to Figure 1 , the upper end of the dyeing tank body 1 is welded and fixed with a top plate 103 through columns, and a hydraulic cylinder 104 is fixedly installed at the lower end of the top plate 103. An exhaust gas recovery mechanism 2 is arranged at the piston end of the hydraulic cylinder 104. The exhaust gas recovery mechanism 2 includes a tank cover plate 201. A fabric inlet groove 208 is provided at the lower part of the tank cover plate 201. The fabric inlet grooves 208 are symmetrically arranged on the side walls of the tank cover plate 201. During dyeing, the hydraulic cylinder 104 extends to drive the tank cover plate 201 to cover the dyeing tank body 1. The height of the fabric inlet groove 208 is about 0.5 mm. Only a small amount of gas will overflow from the fabric inlet groove 208 during the dyeing and boiling process;

[0040] Refer to Figure 1 and Figure 3 , two groups of symmetrically arranged intake elbow pipes 202 are welded and communicated at the upper end of the tank cover plate 201. The end of the intake elbow pipe 202 is welded and communicated with a condensing member 203. Most of the gas will enter the condensing member 203 through the intake elbow pipe 202 and be condensed. The side wall of the condensing member 203 is a double-layer structure, and condensing water pipe joints 209 are welded and communicated on both sides of the condensing member 203. The two condensing water pipe joints 209 are respectively connected to an external water inlet pipe and a water outlet, so as to condense the gas inside the condensing member 203. A frustum-shaped diversion part 210 is integrally formed at the lower part of the condensing member 203. An exhaust gas treatment pipe 204 is welded and communicated at the lower end of the condensing member 203. Part of the condensable gas will flow into the exhaust gas treatment pipe 204 from the diversion part 210 of the condensing member 203;

[0041] Refer to Figure 1 and Figure 3, a side of the waste gas treatment pipe 204 is welded and communicated with an activated carbon water inlet pipe 205. An inlet water blocking plate 206 is slidably connected inside the waste gas treatment pipe 204. When not impacted by water flow, the inlet water blocking plate 206 covers the port of the activated carbon water inlet pipe 205. The included angle between the waste gas treatment pipe 204 and the vertical plane is 30°. Such a setting allows the liquefied gas to flow along one side wall of the waste gas treatment pipe 204, thereby impacting the inlet water blocking plate 206;

[0042] Refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 , two groups of chutes 211 are opened in the waste gas treatment pipe 204, and two groups of sliders 212 are integrally formed on one side of the inlet water blocking plate 206. The inlet water blocking plate 206 is slidably connected inside the waste gas treatment pipe 204 through the cooperation of the chutes 211 and the sliders 212, and the upper end of the inlet water blocking plate 206 is connected to the chutes 211 through a tension spring 207. If there is more gas condensed and liquefied in the upper part, it indicates that the evaporation amount in the printing and dyeing pool body 1 is larger, and the impact force received by the inlet water blocking plate 206 will also be greater. The inlet water blocking plate 206 will move downward more, finally expanding the size of the communication surface between the activated carbon water inlet pipe 205 and the waste gas treatment pipe 204, thereby controlling the liquid flow rate;

[0043] Refer to Figure 1 , a neutralization box 213 is arranged at the lower part of the waste gas treatment pipe 204, and a liquid outlet 214 is opened on the side wall of the neutralization box 213. The lower end of the waste gas treatment pipe 204 is inserted into the liquid in the neutralization box 213. There are some gases with relatively low boiling points in the waste gas treatment pipe 204, which cannot be condensed by the condenser 203, but will be introduced into the liquid in the neutralization box 213 and adsorbed and treated by the activated carbon water. The function of the neutralization box 213 is to allow the waste gas and the activated carbon water to fully contact. After the neutralization box 213 is full, it will flow out from the liquid outlet 214 for collection;

[0044] Refer to Figure 7 a Figure 13, the liquid material inlet 107 is also connected to a dye supply mechanism 3.

The end of the output shaft of the driving motor 305 is connected to the stirring shaft 302 through a transmission member 307, and the stirring shaft 302 is located inside the material tank 301. In this embodiment, the upper end of the transmission member 307 rotates with the protective cover 319 through a first mounting seat, and the lower end of the transmission member 307 rotates with the material tank 301 through a second mounting seat; three stirring blades 304 are arranged on the stirring shaft 302 in the upper, middle, and lower positions. The middle part of the transmission member 307 has a Z-shaped rod part 307a. The middle of the Z-shaped rod part 307a is rotatably connected to one end of a first linkage arm 310. In this embodiment, the middle of the Z-shaped rod part 307a is a round rod section, and one end of the first linkage arm 310 has a circular hole that matches the round rod section; a connecting member 311 is installed at the other end of the first linkage arm 310. The connecting member 311 is rotatably connected to the upper ball head of a second linkage arm 312. In this embodiment, the connecting member 311 has a hemispherical ring 311a that matches the upper ball head; the lower end of the second linkage arm 312 is rotatably connected to an intermediate ring 313, and the intermediate ring 313 is rotatably connected to a base 314. In this embodiment, the length of the second linkage arm 312 can be adjusted as needed. The second linkage arm 312 includes an upper arm and a lower arm. The upper arm and the lower arm are connected by a screw rod. The middle of the screw rod has a handle, and the two ends of the screw rod are respectively threadedly connected to the upper arm and the lower arm, so as to realize the adjustment of the length of the entire second linkage arm 312; the base 314 is fixed on an auxiliary ring 308. The auxiliary ring 308 is vertically slidably connected to the material tank 301. The auxiliary ring 308 is coaxially arranged with the stirring shaft 302 and is located outside the stirring shaft 302. A plurality of liquid passing holes 308a are opened on the auxiliary ring 308. The inside of the auxiliary ring 308 has a material crushing cutter head 308b. The side of the material tank 301 is connected to the liquid material inlet 107 through a supply pipe 318. A valve 317 and an output pump are also provided on the supply pipe 318; a guide vane 308c is provided outside the auxiliary ring 308. A guide rail 315 is vertically installed inside the material tank 301. A guide block 316 is slidably connected to the guide rail 315. The guide block 316 is connected to the auxiliary ring 308 through an inclined rod 320. Through the above solution, the driving motor 305 drives the stirring shaft 302 to rotate, and the stirring shaft 302 drives the stirring blades 304 to rotate. At the same time, the Z-shaped rod part 307a can make the first linkage arm 310 swing up and down. Furthermore, with the cooperation of the second linkage arm 312, the auxiliary ring 308 moves up and down reciprocally.

Finally, it is pulled to the traction roller 102 and passes through between the traction roller 102 and the arc-shaped groove 106. Then, use the hydraulic cylinder 104 to drive the tank cover 201 to cover the printing and dyeing tank body 1, and adjust the fabric to the middle of the fabric inlet slot 208. Then, use the electric heating tube 101 to heat the temperature in the tank. After rising to the predetermined temperature, start the traction roller 102. The gases generated by printing and dyeing and boiling will enter the intake elbow 202 on the tank cover 201, flow into the condensing part 203 to be condensed and further processed.
