Description

Technical Field

[0001] The utility model relates to the technical field of phenolic substance production and recycling device, in particular to a phenolic substance recycling device produced by white leather synthetic tannin. Background Art

[0002] The phenolic substance recycling device for the production of white leather synthetic tannin refers to equipment or technology for recycling and reusing byproduct phenolic substances produced in the process of manufacturing synthetic tannin (a leather tanning agent) in the leather industry. In the leather production process, synthetic tannin is usually produced by reacting phenolic compounds (such as phenol) with aldehyde-containing compounds (such as formaldehyde) under acidic conditions. Phenolic substances are inevitable byproducts in the production process of synthetic tannins. Their recycling and reuse not only contributes to environmental protection and reduces the waste of chemical raw materials, but also reduces production costs. When recycling, first, wastewater containing phenolic substances is collected from the production process of synthetic tannins. These wastewaters may come from reactor washing, product washing or other links in the production process. Phenolic substances in the wastewater may be mixed with other solid particles or suspended matter, so pretreatment is required by precipitation, filtration or other physical methods to remove larger particles of impurities.

[0003] When using a filter element to filter particulate matter in wastewater, the impurities remaining on the filter element will gradually increase as the filtration proceeds. If not cleaned in time, the filter element will be clogged, which will affect the filtration effect and the operating efficiency of the equipment. When cleaning the filter element, the existing device needs to stop the machine, remove the filter element, and then clean the filter element. This method is inefficient and will reduce the efficiency of wastewater filtration. Summary of the invention

Wastewater enters the body 1 through the water inlet 101, and the wastewater entering the body 1 will be filtered, and the particles in the wastewater will enter the water outlet 102 after being filtered, and the filtered wastewater will flow out from the water outlet pipe 103 when the valve is opened, so that the wastewater can be subsequently treated.

[0027] like Figure 1-3 As shown, it also includes a conveying mechanism rotatably mounted on both sides of the machine body 1, the conveying mechanism includes four pulleys 2 rotatably mounted on the machine body 1, the multiple pulleys 2 on both sides of the machine body 1 correspond to each other, a transmission rod 203 is fixedly mounted between the two pulleys 2 on both sides of the machine body 1, a conveyor belt 201 is provided on the four pulleys 2, a filter element 202 is fixedly mounted between the conveyor belts 201 on both sides, a first motor 204 is fixedly mounted in the machine body 1, and the output shaft of the first motor 204 is fixedly connected to one of the pulleys 2. One of the pulleys 2 can be driven to rotate by the first motor 204, the pulleys 2 on both sides can be synchronously rotated by the transmission of the transmission rod 203, the four pulleys 2 can be synchronously rotated by the transmission of the conveyor belt 201, and the conveyor belt 201 drives the filter element 202 to rotate. The wastewater passing through the water inlet 101 will pass through the filter element 202, and the filter element 202 will filter the particulate matter in the wastewater.

[0028] Furthermore, the filter element 202 is formed into a rectangle by four pulleys 2 symmetrically arranged on both sides, so that the wastewater flowing from top to bottom can contact the filter element 202 twice. When the wastewater contacts the filter element 202 for the first time, it contacts the outer surface of the filter element 202, and when the wastewater contacts the filter element 202 for the second time, it contacts the inner surface of the filter element, thereby improving the filtering effect of the wastewater and improving the utilization rate of the filter element 202.

[0029] like Figure 1-2 and Figure 4-6 As shown, two groups of cleaning mechanisms are fixedly installed in the body 1, and one group of cleaning mechanisms includes a backwash assembly installed in the filter element 202 and a roller brush assembly installed on the outside of the filter element 202.

[0030] Furthermore, the backwash assembly includes a support plate 3 fixedly installed in the body 1, a plurality of hoses 312 fixedly installed on the upper and lower sides of the support plate 3, and a nozzle 301 fixedly installed on the hose 312.

The external water source is pumped out by the water pump and transported to the plurality of hoses 312, and finally sprayed out by the nozzle 301, so as to flush the filter element 202. Since the nozzle 301 is located on the other side of the filter element 202 in contact with the wastewater, the filter element 202 can be backwashed. The particles on the filter element 202 can be separated from the filter element 202 to achieve the purpose of cleaning the filter element. A driving plate 302 is fixedly mounted on the multiple hoses 312 on the same side, a slide groove 303 is provided on the support plate 3, a slider 304 is fixedly mounted on the driving plate 302, the slider 304 is slidably connected with the slide groove 303, and a driving assembly for driving the two driving plates 302 to periodically move in opposite directions is installed on the machine body 1. The driving assembly drives the multiple nozzles 301 to swing back and forth, which can improve the uniformity of flushing the filter element 202 and prevent the occurrence of cleaning dead corners.

[0031] The driving assembly includes a second motor 305 fixedly mounted in the machine body 1, an eccentric wheel 306 fixedly mounted on the output shaft of the second motor 305, a first connecting rod 307 rotatably mounted on the eccentric wheel 306, and a driving bar 308 rotatably mounted in the machine body 1.

The two second connecting rods 309 correspond to and are rotatably connected with the two driving plates 302. The second motor 305 drives the eccentric wheel 306 to rotate, which can drive the first connecting rod 307 to swing. The first connecting rod 307 will drive the driving bar 308 to swing back and forth on the machine body 1, so that the driving bar 308 drives the second connecting rod 309 to swing, and then the second connecting rod 309 pushes the driving plate 302 to slide back and forth on the support plate 3. Then the nozzle 301 is driven to swing.

[0032] Among them, a first transmission shaft 310 is fixedly installed between the eccentric wheels 306 on both sides of the body 1, and a second transmission shaft 311 is fixedly installed between the driving bars 308 on both sides of the body 1. Through the transmission of the first transmission shaft 310 and the second transmission shaft 311, the driving plates 302 on both sides of the body 1 can be moved synchronously.

When cleaning the filter element 202, the telescopic motor 403 drives the pressure plate 402 to move toward the filter element 202, and the elastic force of the spring 407 can drive the brush holder 406 to move toward the filter element 202. When the roller brush 408 contacts the filter element 202, the telescopic motor 403 will compress the spring 407, and the spring 407 will increase the friction between the roller brush 408 and the filter element 202. When the roller brush 408 rotates, the particles on the filter element 202 can be cleaned.

[0034] The power assembly includes a transmission belt 409 rotatably mounted on the brush holder 406, a plurality of pulleys on the transmission belt 409 correspond to and are fixedly connected with a plurality of roller brushes 408 one by one, a motor holder 405 is fixedly mounted on the machine body 1, a third motor 410 is fixedly mounted on the motor holder 405, and an output shaft of the third motor 410 is coaxially fixedly connected with one of the pulleys on the transmission belt 409. Starting the third motor 410 can drive the transmission belt 409 to rotate, and the transmission of the transmission belt 409 can make the plurality of roller brushes 408 rotate synchronously.

[0035] Working principle: wastewater enters the body 1 through the water inlet 101 and enters the body 1. The filter element 202 is driven to rotate by the first motor 204. The wastewater passing through the water inlet 101 will pass through the filter element 202, and the filter element 202 will filter the particles in the wastewater. The filtered wastewater will flow out of the outlet pipe 103, and the wastewater can be subsequently treated. When the filter element 202 moves to both sides, the water pump draws out the external water source and sprays it through the nozzle 301, so as to rinse the filter element 202, and because the nozzle 301 is located on the other side where the filter element 202 contacts the wastewater, the filter element 202 can be backwashed. The particles on the filter element 202 can be separated from the filter element 202 to achieve the purpose of cleaning the filter element. At the same time, the third motor 410 drives multiple roller brushes 408 to rotate synchronously. The particles on the filter element 202 can be cleaned.
