Technical Field

[0001] The utility model belongs to the technical field of rubber production, in particular to a styrene-butadiene latex solution conveying device. Background Art

[0002] Styrene butadiene latex is a stable emulsion formed by low-temperature polymerization of butadiene and styrene. There are many varieties, depending on the styrene content, emulsifier and polymerization temperature, and their performance and uses are also different; among them, the styrene butadiene latex used in papermaking needs to be transported during processing, but due to the characteristics of styrene butadiene latex, when it is transported through a pipeline, it is easy to form a latex bonding layer inside the pipeline, affecting the transportation efficiency, so a special latex transportation device is required.

[0003] For example, patent application number CN202222061455.7 discloses a styrene butadiene latex solution conveying device, comprising a base plate, a reactor arranged on the other side of the top surface of the base plate, and a conveying pump arranged on one side of the middle part of the top surface of the base plate, a liquid suction pipe connected to a storage tank is provided at the liquid inlet end of the conveying pump, a filter tank is provided between the conveying pump and the reactor, and an infusion pipe is provided on the top of the filter tank; a partition mechanism for filtering styrene butadiene latex is provided in the filter tank; a scraping mechanism for cleaning the inner wall is provided in the infusion pipe; the utility model has a simple structure, and the partition mechanism is used to prevent styrene butadiene latex blocks from being conveyed into the reactor to affect the reaction and mixing effect with other additives, and the scraping mechanism is used to scrape the styrene butadiene latex on the inner wall of the infusion pipe, so as to prevent the situation in which it is inconvenient to clean the styrene butadiene latex on the inner wall of the infusion pipe due to the long pipe.

[0004] In the prior art, the influence of latex on reaction mixing and clogging of the inner wall of the infusion tube is reduced by setting up a separation mechanism and a scraping mechanism. However, there are still many deficiencies in the overall use process: the latex lumps are formed by long-term storage inside the storage tank. Therefore, reducing the production of latex is essentially the fundamental way to improve the reaction effect of the reactor. However, the prior art only intercepts latex, which is a temporary solution and not a fundamental solution, and the overall practicality is insufficient. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a styrene-butadiene latex solution conveying device.

[0006] The utility model arranges a crushing rod, a filter screen, a vibrator and the like at the mouth of the bell pipe, so that the generation of latex lumps can be reduced during the storage process of latex through the stirring rack and the first heater. In the process of discharging the material outward, the lumps can be crushed, intercepted and heated to melt, so that the lumps can be recovered and dissolved, which not only avoids the influence on the subsequent latex reaction, but also avoids the waste of resources.

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a styrene-butadiene latex solution conveying device, including a storage barrel and a stirring rack, wherein the storage barrel is rotatably provided with a stirring rack, one side of the stirring rack is provided with a discharge nozzle on the outer circumference of the storage barrel, one side of the discharge nozzle is connected with a trumpet nozzle in the storage barrel, a connecting block is provided at the inner center of the trumpet nozzle, a filter is connected between the connecting block and the inner wall of the trumpet nozzle, a connecting disk is rotatably provided on one side of the filter, a plurality of crushing rods are connected on the outer circumference of the connecting disk, each of the outer end faces of the crushing rods is connected with a scraper, one end of the scraper is in contact with the inner circumference of the trumpet nozzle, and a second heater is provided outside the trumpet nozzle. Through the arrangement of the connecting disk and the filter, the emulsion can be fully crushed and refined in the process of being discharged outward, and the dissolution process is completed again.

[0008] Preferably, a fixing seat is fixedly arranged in the trumpet pipe mouth on one side of the connection block, a second drive motor is arranged on the end surface of the fixing seat, an output end of the second drive motor extends out of the end surface of the connection block, and the output end of the second drive motor extending out of the connection block is connected to the connection disk. The arrangement of the second drive motor enables the connection disk to smoothly drive the crushing rod to complete the crushing process.

[0009] Preferably, a first heater is provided on the bottom end surface of the storage barrel. The provision of the first heater can reduce the generation of milk lumps inside the storage barrel.

[0010] Preferably, a plurality of vibrators are arranged on the outer circumferential surface of the bell mouth, a plurality of connection holes are arranged on one side of the vibrator on the end surface of the filter screen, and an output rod is connected between the connection hole seat and the output end of the vibrator. The arrangement of the vibrator enables the filter screen to be cleaned in time, so that the intercepted milk blocks can be broken up for a second time.

[0011] Preferably, a first driving motor is arranged at the top of the storage barrel, and an output end of the first driving motor is connected to a stirring rack. The arrangement of the stirring rack can effectively reduce the generation of milk lumps inside the storage barrel.

In the process of discharging the latex outwards, the lumps can be crushed, intercepted, heated and melted, so that the lumps can be recovered and dissolved, which not only avoids the influence on the subsequent latex reaction, but also avoids the waste of resources.

[0016] The utility model arranges the scraper bar, the vibrator and the connecting hole seat, so that the rubber block particles adhered to the inner wall of the trumpet pipe mouth and filtered out by the filter screen during the crushing process of latex can be recycled for the second time, which effectively improves the recycling effect of the rubber blocks.

[0024] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0025] Embodiment 1:

[0026] refer to Figure 1-7A styrene-butadiene latex solution conveying device comprises a storage barrel 10 and a stirring frame 13. The storage barrel 10 is rotatably provided with the stirring frame 13. A discharge nozzle 11 is provided on one side of the stirring frame 13 on the outer circumferential surface of the storage barrel 10. A bell nozzle 20 is provided in communication with the discharge nozzle 11 on one side of the storage barrel 10. A connecting block 17 is provided at the inner center of the bell nozzle 20. A filter screen 18 is connected between the connecting block 17 and the inner wall of the bell nozzle 20. A connecting disk 26 is rotatably provided on one side of the filter screen 18. A plurality of crushing rods 21 are connected on the outer circumferential surface of the connecting disk 26. A scraper 27 is connected on the outer end surface of each crushing rod 21. One end of the scraper 27 abuts against the inner circumferential surface of the bell nozzle 20. A second heater 19 is provided outside the bell nozzle 20.

[0027] Specifically, the stirring frame 13 is a traditional anchor stirring structure. When the emulsion is stored in the storage barrel 10, the stirring frame 13 can rotate inside the storage barrel 10 to stir the emulsion. The anchor structure can form effective stirring in a relatively thick emulsion and reduce the phenomenon of latex coagulation.

[0028] The discharge pipe opening 11 is externally connected to a peristaltic pump, which can pump out the emulsion inside the storage barrel 10. The trumpet pipe opening 20 interconnected with the discharge pipe opening 11 is trumpet-shaped on the outside, which has a guiding effect and facilitates the emulsion to flow to the discharge pipe opening 11.

[0029] During the process of extracting and discharging the emulsion, the connecting plate 26 will drive the multiple crushing rods 21 on the outer circumferential surface to rotate rapidly. The rotating crushing rods 21 can crush and refine the emulsion that flows to the bell mouth 20. The emulsion with the emulsion particles will flow to the filter screen 18, and then be filtered by the filter screen 18. The filtered emulsion will be discharged outward through the discharge pipe mouth 11, and the filtered particles will be intercepted in the bell mouth 20 pipeline on one side of the filter screen 18. At this time, the second heater 19 arranged on the outer circumferential surface of the bell mouth 20 will be turned on, so that the bell mouth can be cleaned. The nozzle 20 is heated, so that the milk block particles inside the bell nozzle 20 can be heated and melted, so that they can be converted into emulsion again, so that they can be smoothly filtered through the filter 18 and discharged outward. In this process, the rotation of the breaker rod 21 will also drive the scraper bar 27 at one end to rotate, and the outer end of the scraper bar 27 is in contact with the inner surface of the bell nozzle 20. The rotating scraper bar 27 can scrape off the milk block particles adhering to the inner wall of the bell nozzle 20 to avoid blockage, and on the other hand, it can stir the milk block particles, so that the milk block particles are heated more evenly, thereby improving the melting efficiency.

[0030] In the above relationship, this scheme does not impose specific restrictions on the shape of the crushing rod 21, and the illustration is only for reference, so as to meet the crushing requirements; the second heater 19 is a prior art, and the specific heating structure is not elaborated in detail; the filter screen 18 is made of elastic material, and a plurality of filtering holes are arranged on the surface, and the whole has a certain elasticity, and is connected and supported by the connecting block 17 and the inner wall of the bell mouth 20, which can have a certain pressure relief effect when the emulsion flows at a high speed, thereby improving the service life; the connecting block 17 is fixedly connected to the center of the bell mouth 20 through a corresponding structure, and the specific structure is not elaborated in detail in this article.

[0031] refer to Figure 5-7 A fixing seat 22 is fixedly arranged in the trumpet pipe mouth 20 on one side of the connecting block 17, and a second driving motor 16 is arranged on the end surface of the fixing seat 22. The output end of the second driving motor 16 extends out of the end surface of the connecting block 17, and the output end of the second driving motor 16 extending out of the connecting block 17 is connected to the connecting disk 26.

[0032] Specifically, the fixed seat 22 is supported and fixed at the center of the trumpet pipe mouth 20. The second drive motor 16 is a prior art and has a waterproof effect as a whole. This article will not elaborate on it. The output end of the second drive motor 16 can drive the connecting disk 26, so that the connecting disk 26 and the breaking rod 21 outside the connecting disk 26 rotate quickly to complete the crushing and refining processing of the milk block.

[0033] refer to Figure 7 A plurality of crushing teeth 28 are provided on both side end surfaces of the crushing rod 21 .

[0034] Specifically, the crushing teeth 28 are arranged on the end surfaces of both sides of the crushing rod 21, which can effectively improve the crushing efficiency of the milk curd.

[0035] refer to Figure 5 A plurality of vibrators 23 are arranged on the outer circumferential surface of the bell mouth 20, a plurality of connecting holes 24 are arranged on one side of the vibrator 23 on the end surface of the filter screen 18, and an output rod 25 is connected between the connecting hole seat 24 and the output end of the vibrator 23.

[0036] Specifically, the vibrator 23 is of prior art, including a linear motor that can generate high-frequency vibration when powered on. The specific structure and selection will not be elaborated in this article. Multiple vibrators 23 are evenly installed on the outer surface of the trumpet mouth 20 along the circumferential direction. The output end of the vibrator 23 is connected to the output rod 25, and one end of the output rod 25 is embedded in the connecting hole seat 24. The connecting hole seat 24 is arranged on one side end face of the filter screen 18. When the filter screen 18 filters the milk curd particles and some of the milk curd particles accumulate on one side of the filter screen 18 for melting, the vibrator 23 can perform high-frequency vibration on the connecting hole seat 24 through the output rod 25, thereby performing high-frequency vibration on the filter screen 18 made of flexible material, so that the particles accumulated on the end face of the filter screen 18 can be shaken off, reducing the accumulation amount, improving the uniformity of heating, and improving the melting efficiency.

[0037] refer to Figure 4 A first driving motor 14 is disposed at the top of the storage barrel 10 , and an output end of the first driving motor 14 is connected to the stirring frame 13 .

[0038] Specifically, the first driving motor 14 is a prior art and will not be elaborated in detail herein. The output end of the first driving motor 14 can drive the stirring frame 13 to rotate, thereby stirring the emulsion inside the storage barrel 10 .

[0039] refer to Figure 3 A feed pipe opening 12 is provided on the outer circumferential surface of the other side of the storage barrel 10 .

[0040] Specifically, the feed pipe opening 12 is used to pour the emulsion into the storage barrel 10 for storage.

[0041] Embodiment 2:

[0042] On the basis of or different from the first embodiment, reference Figure 4 A first heater 15 is disposed on the bottom end surface of the storage barrel 10 .

[0043] Specifically, the first heater 15 can heat the bottom of the storage barrel 10 so that the interior of the storage barrel 10 is in a constant temperature state. In combination with the fast stirring stirring rack 13, the occurrence of emulsion coagulation can be effectively reduced, thereby improving the discharge efficiency.
