Description

Technical Field

[0001] The invention relates to the technical field of producing chlorinated polyethylene, and in particular to a material distribution device of a chlorinated polyethylene belt-type acid liquid separation system. Background Art

[0002] The preparation methods of chlorinated polyethylene generally include solid phase method and solvent method. The former is to pass chlorine gas into polyethylene solid powder and directly carry out gas-solid reaction in a fluidized bed. However, this method has unstable quality, is difficult to control and easily causes environmental pollution. Therefore, it has been gradually eliminated in recent years. The latter is to dissolve polyethylene in carbon tetrachloride solution and react homogeneously after passing chlorine gas. Although this method is easy to control and has stable quality, carbon tetrachloride is easy to destroy the ozone layer when it enters the atmosphere, thereby causing harm to the environment. Therefore, in recent years, the production of chlorinated polyethylene by aqueous suspension method and acid suspension method has gradually been accepted by more people and widely used in industrial production.

[0003] Since the acid phase suspension method faces the problems of high corrosion resistance requirements for post-processing equipment, high equipment investment costs, and the need to grind the dried materials, which leads to high production costs, more manufacturers are willing to use the water phase suspension method to prepare chlorinated polyethylene. Compared with other methods for preparing chlorinated polyethylene, the water phase suspension method usually has the advantages of less equipment investment, stable product quality and low raw material consumption.

[0004] The aqueous suspension process produces chlorinated polyethylene, where polyethylene fine powder is dispersed into an aqueous solution containing a dispersant and an emulsifier, and chlorine gas is introduced under stirring for chlorination. After the desired chlorine content is reached, deacidification, water washing, neutralization, waste liquid removal, centrifugation, and fluidized bed drying are performed to obtain the chlorinated polyethylene product. In the process of deacidification and water washing in the production process of this method, in order to improve the deacidification efficiency and improve the utilization rate of equipment, a centrifugal dehydration device is also used for deacidification, and then the material is washed and neutralized, and the waste liquid is filtered and then further dehydrated by a centrifugal dehydration device. However, due to the corrosiveness of the acid, the centrifugal device will still be corroded after a period of use, resulting in a high maintenance frequency of the centrifugal device, which will affect the production progress. The applicant submitted a new deacidification and water washing device on the same day, which ensures the deacidification efficiency while not being easily corroded and reducing the maintenance rate. However, in order to ensure the deacidification efficiency, it is necessary to ensure that the material is more evenly distributed before deacidification, so the applicant provides a uniform distribution device for the deacidification and water washing device.

The drainage tank 23 is connected with the drainage device 7 through the drainage main pipe 33 and the drainage branch pipe 24, so that the suction port 42 of the drainage device 7 is connected with the top surface of the upper transmission belt 2 through the liquid hole 36 of the transmission belt 2.

[0079] At this time, the feeding pipe 19 is opened, and the cake washing water supply device is made to supply water to the cake washing water strip tank 22 at the same time.

[0080] The material mixed with chlorinated polyethylene and acid solution enters the horizontal material pipe 18 from the feeding pipe 19. The material entering the horizontal material pipe 18 is quickly dispersed at the bottom of the horizontal material pipe 18. Then the material enters the top surface of the bulk material ramp A53 in the material mixing bin through multiple feeding pipes 20 at the bottom of the horizontal material pipe 18 along the length direction of the horizontal material pipe 18. The inclined mouth 52 provided at the bottom pipe mouth of the feeding pipe 20 makes the material fall to the top of the bulk material ramp A53 as much as possible after falling, thereby ensuring the bulking distance of the material on the bulk material ramp A53. The material falling on the bulk material ramp A53 moves downward and slides down along the bulk material ramp A53 under the action of gravity and the continuous falling of the feeding pipe 20. In the process of the material moving along the bulk material ramp A53, Through the action of the bulk material protrusion 54, the material on the bulk material ramp A53 is more dispersed and flows more evenly on the top surface of the bulk material ramp A53. When the material flows through the blanking through hole 60 of the bulk material ramp A53, part of the material will fall through the blanking through hole 60 to the top surface of the bulk material ramp D61 and move downward along the bulk material ramp D61, so that the excess material on the top surface of the bulk material ramp A53 is diverted to the bulk material ramp D61, thereby making the material on the surface of the bulk material ramp A53 more dispersed; in the process of the material moving along the bulk material ramp D61, through the action of the bulk material protrusion 54, the material on the bulk material ramp D61 is more dispersed and flows more evenly on the top surface of the bulk material ramp D61; from the bottom edge of the bulk material ramp A53, the material on the bulk material ramp D61 is more dispersed and flows more evenly on the top surface of the bulk material ramp D61. The materials sliding down from the bottom edge of the bulk material ramp D61 rush toward the end face of the end stand B51 facing the end stand A50. The materials on the end face of the end stand B51 flow downward under the action of gravity. When the materials pass through the material leveling protrusion A62, the material leveling protrusion A62 will make the materials flowing through flow to both sides of the end stand B51 while they are sliding down, so as to avoid the materials gathering in the middle of the end stand B51. When the materials pass through the material leveling protrusion B63 downward, the material leveling protrusion B63 will further disperse the materials flowing through. The materials slide down from top to bottom along the end stand B51 to the bulk material ramp B55. Since the inclination angle of the bulk material ramp B55 is very small, the materials can form a laminar flow along the bulk material ramp B55 and continue to slide downward and pass through. The material passes through the guide plate A64 and enters the guide hole 57 formed between the guide plate 56 and the end plate A50 and between the guide plate B65 and the bulk material slope C58. After passing through the guide hole 57, the material flows downward at a faster speed due to gravity. Finally, the material continues to flow downward along the bulk material slope C58 to the arc plate 59 at the bottom. Due to the Coanda effect, the flow direction of some materials on the surface of the arc plate 59 deviates along the arc plate 59 and then separates from the arc plate 59. The part of the material far from the surface of the arc plate 59 will separate from the bulk material slope C58 along the direction of the bulk material slope C58 due to inertia, so that the material can be more dispersed and evenly dropped on the top surface of the filter cloth belt 3 just passing under the material distribution device 5.After leaving the bulk material ramp C58 and the curved plate 59, the material will be affected by its own gravity and form a parabola before falling onto the top surface of the filter cloth belt 3, and the falling speed will be further accelerated. ;

[0081] Due to the action of the pressure roller 15 and the negative pressure of the drainage device 7, the filter cloth belt 3 will fit tightly to the top surface of the transmission belt 2; so when the material finally falls onto the top surface of the filter cloth belt 3, during the transmission process of the filter cloth belt 3 and the transmission belt 2, the material will flow along the surface of the transmission belt 2 to the strip liquid collecting groove 37, and quickly converge along the bottom of the strip liquid collecting groove 37 to the liquid through hole 36 in the middle, and the acid in the material can pass through the filter cloth belt 3 and downward into the drainage groove 43 of the drainage device 7 through the liquid through hole 36, and then the acid enters the drainage tank 23 through the drainage branch pipe 24 and the drainage main pipe 33 in turn through the negative pressure. When the acid in the drainage tank 23 is more, it is discharged and collected through the drainage port 32 at the bottom of the drainage tank 23; while the chlorinated polyethylene in the material is blocked by the filter cloth belt 3 and filtered out, and still remains on the top surface of the filter cloth belt 3 to gather to form a material cake. The strip grooves A38 and B39 in the strip liquid collecting tank 37 can not only facilitate the rapid separation of the acid liquid from the chlorinated polyethylene at the corresponding position, but also enable the separated acid liquid to quickly converge to the liquid through hole 36, and also facilitate the chlorinated polyethylene after filtration to gather and form cakes. The strip grooves B39 can also facilitate the transmission belt 2 at the corresponding position of the liquid through hole 36 to be slightly deformed downward under the negative pressure of the liquid discharge device 7, so that the bottom of the upper transmission belt 2 corresponding to the position of the liquid through hole 36 is tilted downward along the direction close to the liquid through hole 36, thereby further ensuring that the acid liquid flowing out of the liquid through hole 36 can be completely immersed in the liquid discharge device 7, and the acid liquid is prevented from escaping to both sides along the bottom of the transmission belt 2.

[0082] As the transmission belt 2 continues to drive, the chlorinated polyethylene cake from which the acid has been filtered out on the filter cloth belt 3 is transmitted to the position directly below the cake washing water outlet device 6, so that the cake washing water rinses the chlorinated polyethylene cake; then the rinse water that has rinsed the chlorinated polyethylene cake is separated from the chlorinated polyethylene through the drainage device 7 like the previous acid liquid and enters the drainage tank 23, while the chlorinated polyethylene remains on the top surface of the filter cloth belt 3 and still gathers to form a cake.

[0083] After the filter cloth belt 3 is separated from the transmission belt 2, the chlorinated polyethylene cake continues to be transmitted under the action of the filter cloth belt 3 until the filter cloth belt 3 transmits the chlorinated polyethylene cake to the filter cake receiving trough 8; when the filter cloth belt 3 in the filter cake receiving trough 8 is wound around the transmission roller B12 in the filter cake receiving trough 8 so that the filter cloth belt 3 gathers the chlorinated polyethylene cake with the end face facing downward, the chlorinated polyethylene cake will be separated from the filter cloth belt 3 under the action of gravity and fall into the filter cake receiving trough 8; when passing through the cloth washing spray pipe 13, the cloth washing spray pipe 13 sprays the filter cloth belt 3 is sprayed at the bottom, so that the chlorinated polyethylene remaining on the bottom of the filter cloth belt 3 is separated from the filter cloth belt 3 and falls into the filter cake collecting trough 8; when the filter cloth belt 3 after being sprayed by the cloth washing spray pipe 13 is transmitted to the cloth washing air jet pipe 14, the cloth washing air jet pipe 14 sprays the top surface of the filter cloth belt 3 downward, so that the chlorinated polyethylene and cloth washing water remaining at the bottom of the filter cloth belt 3 are completely separated from the filter cloth belt 3, thereby ensuring that the filter cloth belt 3 can filter the material mixed with chlorinated polyethylene and acid solution again after being driven by the transmission belt 2.

[0084] When the mixture of chlorinated polyethylene and water in the filter cake receiving tank 8 is relatively large, it can be discharged through the filter cake discharge port 9 and transferred to the next process.

[0085] During the transmission process of the transmission belt 2, the transmission belt 2 cooperates with the annular positioning groove corresponding to the transmission roller A10 through the annular sealing strip 40, so that the transmission belt 2 will not deviate laterally.

[0086] During the transmission process of the filter cloth belt 3, when the filter cloth belt 3 deviates laterally, the sensor 28 detects the lateral deviation of the filter cloth belt 3, sends a signal to the filter cloth belt correcting device 27, and controls the filter cloth belt correcting device 27 to correct the lateral deviation of the filter cloth belt 3; thereby, the filter cloth belt 3 is in dynamic stability with the side of the transmission belt 2 during the transmission process.

[0087] During the transmission process of the transmission belt 2, the transmission belt 2 is connected to the driven transmission belt 4 through static friction, thereby avoiding sliding friction between the transmission belt 2 and the base frame 1, extending the service life of the transmission belt 2, and the driven transmission belt 4 plays a role of uniformly supporting the entire upper transmission belt 2, ensuring the horizontal state of the upper transmission belt 2.

[0088] In the above embodiment:

[0089] The negative pressure can effectively separate the acid liquid from the chlorinated polyethylene in the chlorinated polyethylene acid solution, and can also be filtered and collected again after water washing, which effectively ensures the deacidification and water washing effect while effectively reducing the maintenance rate and ensuring the normal production of chlorinated polyethylene.

[0090] The strip-shaped liquid collecting grooves and the strip-shaped grooves A and B provided by the transmission belt facilitate the effective separation and filtration of the chlorinated polyethylene and the acid solution.

[0091] The strip groove B can also form a micro-deformation at the bottom of the upper transmission belt corresponding to the position of the liquid through hole under the negative pressure of the drainage device, thereby ensuring that all the liquid flowing out of the bottom of the liquid through hole is sucked into the drainage device to avoid escaping from both sides along the bottom of the transmission belt.

[0092] Through the action of the annular sealing strip, not only can a liquid seal be formed with the liquid sealing groove of the drainage device, thereby avoiding negative pressure leakage of the drainage device and affecting the filtering effect of chlorinated polyethylene, but also the sealing water can be used to make the direct contact medium during the sliding connection between the transmission belt and the base frame be sealing water, so that there is no sliding friction between the transmission belt and the base frame during the transmission process, thereby extending the service life of the transmission belt.

[0093] Through the action of the slave transmission belt, not only can the sliding friction between the transmission belt and the base frame be further converted into rolling friction between the transmission roller of the slave transmission belt and the bracket fixed on the base frame, further reducing friction, reducing energy consumption and extending the service life of the transmission belt; in addition, the slave transmission belt can play a role in uniformly supporting the bottom of the upper transmission belt, thereby ensuring the level of the upper transmission belt.

[0094] A sealing cavity can be formed between two adjacent sealing rings through the action of sealing water, thereby further improving the sealing effect of the annular sealing strip.

[0095] Through the filter cloth belt deviation correction device and the sensor, the lateral direction of the filter cloth belt and the transmission belt is dynamically stable during the transmission process, thereby ensuring the filtering effect of the filter cloth belt.

[0096] Through the functions of the cloth washing spray pipe and the cloth washing air jet pipe, the residual chlorinated polyethylene on the filter cloth belt can be completely separated from the filter cloth belt and dropped into the filter cake collecting trough, which not only facilitates the next step after the chlorinated polyethylene is collected, but also ensures that the filter cloth belt is transmitted again to fit with the upper transmission belt to filter the material mixed with chlorinated polyethylene and acid solution again.

[0097] Through the function of the cloth device, the mixture of chlorinated polyethylene and acid solution can be effectively and evenly dropped onto the filter cloth belt, thereby facilitating efficient filtration by the filter cloth belt.
