Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of color enhancer surface treatment device, in particular to a CBS water washing and filtering device and process. BACKGROUND

[0002] CBS(CZ) is a highly active aftereffect accelerator, which has excellent anti-scorching performance, safe processing and short curing time. Alkaline accelerators such as thiuram and dithio carbamate can enhance its activity. It is mainly used for manufacturing industrial rubber products such as tires, hoses, shoes and cables.

[0003] In the production of CBS, domestic rubber additive manufacturers currently use hydrogen peroxide oxidation method, oxygen oxidation method and electrolytic oxidation method to produce accelerator CBS by mainly using sodium hypochlorite oxidation method. This process has low raw material cost, stable process control, simple equipment and high product yield (more than 90%). The biggest problem is that the wastewater discharge is large (5-6 tons per ton of product) and difficult to treat, and direct discharge of wastewater causes environmental pollution.

[0004] The existing CBS involves filtering work in the manufacturing process. Filtering is a common method for solid-liquid separation, which is reduced pressure filtration or vacuum filtration. In actual production equipment, a water washing kettle, a mother liquor tank, a buffer tank, a water pump and a vacuum pump are mainly needed. When the water washing kettle and the mother liquor tank are connected for filtering, according to the actual provisions, after the mother liquor tank is extracted to a certain scale, the vacuum pump needs to be closed, and then the water valve, the exhaust valve on the pump and the filtering pipeline at the water washing kettle are sequentially closed. Finally, the collected mother liquor in the mother liquor tank is discharged into a collection tank for treatment, and then the water washing kettle is filled with materials for filtering. This may cause the mother liquor for stirring materials to exist in the water washing kettle. After the vacuum pump is first closed, each pump and valve needs to be manually closed. Since the water washing kettle contains mother liquor, the mother liquor will flow into the mother liquor tank through the filter screen (plate) due to the negative pressure in the pipeline and the self-weight of the mother liquor during the time of manually closing the valve and pump body. According to the existing production, the water, the material and the mother liquor are in equal proportion, and the amount of water is much larger than that of the material. The reason for extracting the mother liquor tank to a certain scale is: first, to reduce the wastewater discharge after water washing of the material within the specified quality, and second, to facilitate the recovery of cyclohexylamine. This method is not conducive to the accurate control of the liquid level of the accumulated liquid in the mother liquor tank during the process of closing the valves by the operator. Therefore, we propose a CBS water washing and filtering device and process. SUMMARY

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0027] Please refer to Figures 1-10 The present application provides a technical solution: a CBS water washing and filtration device and process, comprising a workbench 5, a water washing kettle 1 arranged on the top of the workbench 5, a buffer tank 9 connected to the bottom of the workbench 5 through a pipeline and a master batch tank 8 arranged at the bottom of the buffer tank 9, a butterfly valve 3 installed between the water washing kettle 1 and the buffer tank 9, and a flow control device arranged on the top of the master batch tank 8 for controlling the flow of mother liquor in the water washing kettle 1. The buffer tank 9 is connected to a vacuum pump pipeline outside. The present application saves manual operation time and avoids manual errors or slow operation to increase wastewater discharge. The butterfly valve 3 is associated with the flow control device. The flow control device rises in the master batch tank 8. When the highest liquid level of the master batch tank 8 reaches a preset value, the butterfly valve 3 is directly controlled to be closed by the flow control device. Then the water washing kettle 1 will not flow into liquid to the master batch tank 8.

[0028] The flow control device comprises a communicating channel 6 communicating with the mother liquor tank 8 and arranged at one side of the top of the mother liquor tank 8, a sealing plate 601 arranged at the top of the communicating channel 6, a limiting plate 602 arranged inside the communicating channel 6 at a position close to the bottom of the sealing plate 601, a movable column 605 slidingly connected to the middle of the sealing plate 601 and the limiting plate 602, a depth adjusting plate 603 sleeved on the outer circle of the movable column 605, a float plate 604 arranged at the bottom of the movable column 605, and a driving device arranged at the top of the float plate 604 and used for opening and closing the butterfly valve 3. Since the mother liquor tank 8 and the communicating channel 6 are in communication, as shown in the drawing 1, a communicating channel 6 is also arranged at the other side of the top of the mother liquor tank 8 in the drawing, the communicating channel 6 is in a sealing state and communicates with the communicating channel 6 provided with the sealing plate 601, facilitating the rising of the liquid level. When the mother liquor tank 8 enters the mother liquor process, after the mother liquor tank 8 is filled with the mother liquor, the liquid level rises to the two communicating channels 6, then the float plate 604 is driven to rise, and in the process of rising of the float plate 604, the movable column 605 moves in the middle of the sealing plate 601 and the limiting plate 602 (a sealing ring is arranged in the middle of the sealing plate 601, and the movable column 605 moves outside the circle of the sealing ring, so that air is not introduced into the communicating channel 6 in the process of moving of the movable column 605 outside the circle of the sealing ring, thereby reducing the internal pressure of the communicating channel 6). When the depth adjusting plate 603 contacts the limiting plate 602, that is, after the liquid level in the mother liquor tank 8 reaches the preset value, the driving device is driven through the linkage effect of the top of the movable column 605 to rotate and lock the disc of the butterfly valve 3, so that the washing kettle 1 does not leak liquid. The operation function of the driving device is described as follows:

[0029] The driving device comprises a rotary adjusting member 17 slidingly connected to the movable column 605, a limiting piece 13 fixed to the rotary adjusting member 17, a support 7 fixed to the mother liquor tank 8, a supporting rod 16 arranged at the top of the support 7 and used for preventing the movable column 605 from deviating, a sleeve 15 arranged at the top of the supporting rod 16, a spring 14 fixed to the inner circle of the sleeve 15 and abutting against one end of the limiting piece 13, and a transmission device arranged at the side of the limiting piece 13 away from the spring 14. The spring 14 is initially in a passive compression state. When the movable column 605 rises in the process, the rotary adjusting member 17 is driven to rise synchronously, the rotary adjusting member 17 drives the limiting piece 13 to rise synchronously, as shown in the drawing 8, the limiting piece 13 is composed of a straight sliding groove and a circular-arc sliding groove. The circular-arc sliding groove can pass through the spring 14, and the straight sliding groove directly abuts against one end of the spring 14. When the limiting piece 13 rises with the rotary adjusting member 17, the spring 14 initially slides along the straight sliding groove of the limiting piece 13 to the circular-arc sliding groove. After the spring 14 contacts the circular-arc sliding groove, the spring 14 is instantaneously actively expanded to drive the transmission device to move, so that the butterfly valve 3 locks the inside of the pipeline.
