Description

Technical Field

[0001] The utility model relates to the technical field of waste liquid concentration, in particular to a waste liquid concentration device for producing fluorescent whitening agents. Background Art

[0002] At present, fluorescent whitening agent is a fluorescent dye, or white dye, which is also a general term for a class of compounds. Its characteristic is that it can excite incident light to produce fluorescence, so that the dyed substance obtains a sparkling effect similar to fluorite, making the substance appear very white to the naked eye.

[0003] Among them, fluorescent whitening agents will inevitably produce waste liquid during the production process. The main hazards of fluorescent whitening agent waste liquid include impacts on the environment and human health. Fluorescent whitening agent waste liquid contains a large amount of harmful substances, such as benzene and its derivatives. These substances have strong biological toxicity and are difficult to biodegrade, posing a serious threat to the environment and human health. Therefore, the fluorescent whitening agent waste liquid needs to be concentrated to facilitate the purification of the fluorescent whitening agent waste liquid.

[0004] Conventional waste liquid concentrators on the market have difficulty in heating the waste liquid evenly and are not easy to clean the heated particulate matter. Therefore, we propose a waste liquid concentrator for the production of fluorescent whitening agents to solve the above problems. This device can achieve efficient and uniform heating of the waste liquid and complete the separation of water vapor and particulate matter. Utility Model Content

[0005] The purpose of the utility model is to solve the problems existing in the prior art and to propose a waste liquid concentrating device for producing fluorescent whitening agents.

[0010] Preferably, a motor is fixedly installed on one side of the bottom of the concentration tank, the driving output end of the motor is connected to the transmission shaft, and the other end of the transmission shaft is fixedly installed on the gear center axis to drive the gear to rotate.

[0011] Preferably, the other end of the bottom of the concentration tank is connected to a material guide pipe, and the other end of the material guide pipe is connected to the top of the collection box. A cleaning door is installed on the side wall of the collection box by rotating through a hinge to facilitate the collection of particulate matter inside the collection box.

[0012] Preferably, a filter cartridge is fixedly installed on one side of the collection box, and the filter cartridge corresponds to the material guide pipe. A pump is fixedly installed on the bottom side of the collection box, and the pump is connected to the waste liquid nozzle at the other end through a conduit, so that the waste liquid inside the collection box can be introduced into the concentration tank.

In conjunction with the hydraulic push rod on the top of the concentration tank, the cleaning ring at the bottom of the support frame can be pushed up and down. When the cleaning ring reciprocates on the outer wall of the heating cover, the particulate matter attached to the outer wall of the heating cover is efficiently cleaned and concentrated inside the collection box.

[0016] A filter cartridge is fixedly installed on one side of the collection box, and a pump is fixedly installed on the bottom side of the collection box. When the high-temperature heated waste liquid particles are mixed with the waste liquid and introduced into the collection box, the particles can be collected by installing a filter cartridge with smaller filter holes inside the collection box.

[0023] The waste liquid concentration mechanism includes a heating cover 2 rotatably mounted on the bottom side of the concentration tank 12, a plurality of groups of equidistantly distributed heating rods 21 fixedly mounted on the inner wall of the heating cover 2, a gear ring 22 fixedly mounted on the bottom of the side wall of the heating cover 2, a gear 23 meshing with the gear ring 22, a hydraulic push rod 24 fixedly mounted on the top of the concentration tank 12, a support frame 25 fixedly mounted on the other end of the hydraulic push rod 24, and a cleaning ring 26 fixedly mounted on the bottom of the support frame 25. A liquid level sensor is installed inside the collection box 1, and the cleaning ring 26 corresponds to the heating cover 2. Two adjacent groups of heating rods 21 are connected by a The wires are fixedly connected, and the gear 23 inside the waste liquid concentration mechanism is driven to rotate by the driving motor 3. The gear ring 22 meshing with the gear 23 will drive the heating cover 2 to rotate, which can ensure that the fluorescent whitening agent waste liquid is evenly sprayed on the outer wall of the heating cover 2, and a large amount of waste liquid is heated at high temperature to achieve separation of water vapor and particulate matter. In conjunction with the hydraulic push rod 24 on the top of the concentration tank 12, the cleaning ring 26 at the bottom of the support frame 25 can be pushed up and down. When the cleaning ring 26 moves back and forth on the outer wall of the heating cover 2, the particulate matter attached to the outer wall of the heating cover 2 is efficiently cleaned and concentrated inside the collection box 1.

[0024] Furthermore, a guide pipe 31 is installed at the other end of the bottom of the concentration tank 12, and the other end of the guide pipe 31 is connected to the top of the collection box 1. A cleaning door 34 is installed on the side wall of the collection box 1 through a hinge to facilitate the collection of particulate matter inside the collection box 1. A filter cartridge 32 is fixedly installed on one side of the interior of the collection box 1, and the filter cartridge 32 corresponds to the guide pipe 31. A pump 33 is fixedly installed on the bottom side of the interior of the collection box 1, and the pump 33 is connected to the waste liquid nozzle 13 at the other end through a conduit, so that the waste liquid inside the collection box 1 can be introduced into the concentration tank 12. When the high-temperature heated waste liquid particulate matter is mixed with the waste liquid and introduced into the collection box 1, the filter cartridge 32 with smaller filter holes is installed in the collection box 1 to collect the particulate matter. When a small amount of waste liquid reaches the set value of the liquid level sensor, the pump 33 will be driven to introduce the waste liquid into another set of liquid spray nozzles, and sprayed on the outer wall of the heating cover 2 again for solid-liquid separation, thereby further improving the concentration efficiency of the fluorescent whitening agent waste liquid.

[0025] Furthermore, limiting holes 4 are provided on both sides of the top of the support frame 25, and limiting rods 41 are movably installed in the two groups of limiting holes 4.

[0027] When in use, firstly, the waste liquid inside the fluorescent whitening agent waste liquid tank is continuously introduced into a group of waste liquid nozzles 13, so that a large amount of fluorescent whitening agent waste liquid can be sprayed on the outer wall of the heating cover 2, and then the multiple groups of heating rods 21 on the inner wall of the heating cover 2 are opened to heat the outer wall of the heating cover 2 to a sufficient temperature. At the same time, the driving motor 3 drives the gear 23 inside the waste liquid concentration mechanism to rotate, and the gear ring 22 meshing with the gear 23 drives the heating cover 2 to rotate, which can ensure that the fluorescent whitening agent waste liquid is evenly sprayed on the outer wall of the heating cover 2, and a large amount of waste liquid is heated at high temperature to achieve separation of water vapor and particulate matter. The hydraulic push rod 24 on the top of the concentration tank 12 can push the cleaning ring 26 at the bottom of the support frame 25 to move up and down. When the cleaning ring 26 moves back and forth on the outer wall of the heating hood 2, the particulate matter attached to the outer wall of the heating hood 2 is efficiently cleaned and concentrated inside the collection box 1. At the same time, a filter cartridge 32 is fixedly installed on one side of the collection box 1, and a pump 33 is fixedly installed on the bottom side of the collection box 1. When the high-temperature heated waste liquid particulate matter is mixed with the waste liquid and introduced into the collection box 1, the particulate matter can be collected by installing a filter cartridge 32 with smaller filter holes inside the collection box 1. When a small amount of waste liquid reaches the set value of the liquid level sensor, the pump 33 will be driven to introduce the waste liquid into another group of liquid spray nozzles, and spray it on the outer wall of the heating hood 2 again to perform solid-liquid separation, thereby further improving the concentration efficiency of the fluorescent whitening agent waste liquid.
