Description

Technical Field

[0001] The utility model belongs to the field of screw conveying equipment, and particularly relates to a conveying device for cracked carbon black. Background Art

[0002] At present, during the conveying process of cracked carbon black, the demand for ultra-long-distance conveying is increasing. However, the ultra-long spiral shaft is prone to flexure and deformation, and there are problems such as difficult processing and installation. Therefore, in the prior art, a multi-section spiral shaft is mostly adopted, and this multi-section spiral shaft is currently usually connected and fixed by a hanging shaft bearing. However, the existing hanging shaft bearings have some obvious disadvantages, which are specifically as follows:

[0003] 1. The outer diameter of the housing of the existing hanging shaft bearing is generally larger than the outer diameter of the spiral shaft. Coupled with the connecting plate above the hanging shaft bearing housing, this leads to easy material blockage when the spiral shaft conveys materials such as cracked carbon black, which not only affects the continuous operation of the equipment but may also cause the equipment to stop, increasing the maintenance cost.

[0004] 2. When the hanging shaft bearing is damaged, the entire spiral shaft at both ends of the hanging shaft bearing needs to be removed before the bearing can be disassembled and replaced. For an ultra-long spiral shaft, the weight of a single spiral shaft is usually heavy, and the removal difficulty is relatively large, which is time-consuming and laborious, increasing the complexity and workload of maintenance.

[0005] 3. The existing hanging shaft bearings generally adopt a single-layer sealing structure, that is, only sealing rings are provided at both ends of the bearing for sealing. Such a design has a poor sealing effect and is prone to impurities entering the bearing, affecting the normal operation and service life of the bearing.

[0006] 4. The existing hanging shaft bearings usually have no oil injection holes or are inconvenient for oil injection, so the bearing lubrication is inconvenient and the wear is relatively fast. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be described and explained below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments provided by the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0035] The purpose of the present utility model is to provide a reliable-structured and stable-conveying cracking carbon black conveying device for the defects and deficiencies of the prior art, which can effectively avoid spiral blockage of materials and unsmooth spiral conveying caused by external bearings, etc.

[0036] In order to make the above-mentioned purposes, features and advantages of the present utility model more obvious and understandable, the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0037] An embodiment of the present utility model provides a cracking carbon black conveying device. Referring to Figures 1 - 5 as shown, the device includes multiple sections of spiral shafts 1 and two bearing sleeve connecting shafts 2 arranged between adjacent spiral shafts 1; the bearing sleeve connecting shaft 2 includes a nested portion 201 and a connecting portion 202, and the nested portion 201 is fitted inside the spiral shaft 1; a cavity 203 is provided in the connecting portion 202, and a bearing device 3 for connecting with the connecting portion 202 of another bearing sleeve connecting shaft 2 is arranged in the cavity 203. The present utility model places the bearing device 3 inside the cavity 203 of two adjacent bearing sleeve connecting shafts 2 to avoid phenomena such as spiral blockage of materials and unsmooth spiral conveying caused by the external bearing device 3; the connecting portions 202 of two adjacent bearing sleeve connecting shafts 2 are connected by the bearing device 3, and the nested portion 201 is fitted inside the spiral shaft 1 and connected to the spiral shaft 1. When power is provided to one of the spiral shafts 1, the torque on the spiral shaft 1 is transmitted to the bearing device 3 through the connected bearing sleeve connecting shaft 2, and then the torque on the bearing device 3 is transmitted to another bearing sleeve connecting shaft 2, and finally transmitted to another spiral shaft 1, thereby realizing the synchronous rotation operation and continuous transmission action of the entire device. This design not only simplifies the connection structure but also enhances the stability of the transmission.

[0038] In some embodiments, a plurality of positioning pin holes are provided on the nested portion 201, and a plurality of positioning pin holes corresponding to the positioning pin holes on the nested portion 201 are provided on the spiral shaft 1, and the two are fixedly connected by positioning pins.

[0039] Furthermore, the connecting portion 202 is provided with an exposed portion that is exposed outside the spiral shaft 1 and can slide inside the spiral shaft 1, and twice the length of the exposed portion is not less than the length of the bearing device 3. In the present utility model, twice the length of the exposed portion is not less than the length of the bearing device 3. In order to facilitate the maintenance and replacement of the bearing, it is not necessary to remove the spiral shaft 1. Only the two bearing sleeve connecting shafts 2 need to be moved to the left and right respectively, so that the bearing device 3 is completely exposed, and then the disassembly, maintenance and replacement of the bearing device 3 can be realized, which is time-saving and labor-saving and has the characteristics of convenient installation and maintenance.

[0040] Furthermore, the bearing device 3 includes an intermediate shaft 301, a bearing 302, and a bearing sleeve 303. Both ends of the intermediate shaft 301 are respectively disposed within two adjacent connecting portions 202 and connect the two adjacent connecting portions 202; the bearing 302 is sleeved outside the intermediate shaft 301; the bearing sleeve is sleeved outside the bearing 302 and is confined within two cavities 203. In the present utility model, the two adjacent bearing sleeve connecting shafts 2 are connected by the intermediate shaft 3, and the nested portion 201 is connected to the spiral shaft 1. When power is provided to one of the spiral shafts 1, the torque on the spiral shaft 1 is transmitted to the intermediate shaft 301 through the connected bearing sleeve connecting shaft 2, and then the torque on the intermediate shaft 301 is transmitted to the other bearing sleeve connecting shaft 2, and finally transmitted to the other spiral shaft 1, thereby realizing the synchronous rotation operation and continuous transmission action of the entire device. This design not only simplifies the connection structure but also enhances the stability of the transmission; the application of the bearing 302 reduces the frictional loss of the intermediate shaft 301 and extends the service life; the bearing sleeve 303 effectively protects the bearing 302 from the influence of the external environment and further improves the reliability of the device.

[0041] In some embodiments, a plurality of positioning pin holes are correspondingly provided on both ends of the intermediate shaft 301 and the connecting portion 202, and fixed connection is achieved through positioning pins; through this connection method, the firmness and stability of the entire device can be greatly improved.

[0042] In some embodiments, two or more bearings 302 are sleeved outside the intermediate shaft 301, which can not only reduce the disassembly and replacement frequency of the bearings but also greatly reduce the labor force.

[0043] Furthermore, the bearing sleeve 303 is of a split structure. The bearing sleeve 303 includes an upper bearing sleeve cover 3031 and a lower bearing sleeve cover 3032, and the upper bearing sleeve cover 3031 and the lower bearing sleeve cover 3032 are detachably connected. By adopting the split-structured bearing sleeve 303, convenient disassembly and assembly of the bearing 302 can be realized. The upper bearing sleeve cover 3031 and the lower bearing sleeve cover 3032 are detachably connected, which is convenient for maintaining and replacing the bearing 302 and ensuring the long-term stable operation of the device. This design significantly improves the maintenance convenience of the bearing 302. Through the split-structure design, the disassembly and assembly are more convenient, saving maintenance time and cost. At the same time, through the detachable connection method, the reliability and stability of the bearing sleeve 303 are ensured, and the overall performance of the device is improved.

[0044] In some embodiments, the split structure of the bearing sleeve 303 can adopt various connection methods, such as bolt connection, snap connection, etc., to meet different maintenance requirements.

[0045] Furthermore, the cracked carbon black conveying device further includes a spiral housing 4 and a plurality of bearing maintenance covers 5.

A plurality of bearing maintenance covers 5 are connected to one end of the spiral housing 4 where the maintenance opening 401 is provided, and the plurality of bearing maintenance covers 5 are detachably connected to each other. This design greatly improves the maintainability of the device. By providing the maintenance opening 401 and the detachable bearing maintenance covers 5, it is convenient to inspect, maintain, and replace the internal components, reducing the downtime and maintenance costs. At the same time, the integrity and sealing of the spiral housing 4 are ensured, enhancing the reliability of the device.

[0046] In some embodiments, the size and position of the maintenance opening 401 can be adjusted according to actual needs to better adapt to different maintenance requirements. The connection method of the bearing maintenance cover 5 can also be selected according to the actual situation, such as using a quick disassembly and assembly structure to improve the maintenance efficiency.

[0047] Furthermore, the cracked carbon black conveying device further includes a plurality of adjusting screws 6. The adjusting screws 6 pass through the bearing maintenance covers 5 and are threadedly connected to the bearings 302 and abut against the intermediate shaft 301. This design realizes the precise adjustment of the bearings 302 and the intermediate shaft 301 through the adjusting screws 6, effectively preventing problems such as reduced transmission efficiency and wear caused by position deviation, improving the running stability and service life of the device. At the same time, the design of the adjusting screws 6 makes the adjustment of the device more simple and rapid, enhancing the maintenance efficiency.

[0048] Furthermore, the inside of the adjusting screw 6 is hollow. The adjusting screw 6 is designed to be hollow. This design not only reduces the weight of the adjusting screw 6 but also allows lubricating oil to be injected through the hollow part when needed. Lubricating oil can be injected into its interior to further lubricate the bearings 302 and improve the service life of the bearings 302.

[0049] Furthermore, the outer diameter of the connecting portion 202 is the same as the outer diameter of the spiral shaft 1, and spiral blades 7 are provided on the outer sides of the connecting portion 202 and the spiral shaft 1. This design ensures the smoothness and consistency during the transmission process by unifying the outer diameters of the connecting portion 202 and the spiral shaft 1, reducing transmission problems caused by outer diameter differences and phenomena such as discontinuous material conveying or material blocking. The setting of the spiral blades 7 further improves the transmission efficiency, enabling the device to operate more efficiently and stably during operation.

[0050] Furthermore, the cracked carbon black conveying device further includes a bearing gland 8, which is arranged at the left and right ends of the bearing 302. By providing the bearing gland 8, the stability of the bearing 302 during operation is ensured, preventing displacement and loosening, and improving the overall reliability of the device. At the same time, the application of the bearing gland 8 also helps to extend the service life of the bearing 302 and improve the operating efficiency of the entire cracked carbon black conveying device.

[0051] Furthermore, a first seal 9 is provided between the bearing sleeve 303 and the spiral shaft 1, and a second seal 10 is provided between the bearing gland 8 and the bearing 302. By designing the first seal 9 and the second seal 10 and adopting double seals, the sealing performance and wear resistance of the entire device are greatly improved, ensuring the cleanliness and lubrication inside the bearing 302, reducing the wear of the bearing 302, and increasing the service life of the entire device.

[0052] In some embodiments, the material and structure of the first seal 9 can be adjusted according to different use environments, such as selecting high-temperature resistant and corrosion-resistant materials to meet different working conditions. The shape and size of the first seal 9 can also be optimized according to actual needs to ensure the best sealing effect.

[0053] In some embodiments, the material and structure of the second seal 10 can be adjusted according to different use environments, such as selecting high-temperature resistant and corrosion-resistant materials to meet different working conditions. The shape and size of the second seal 10 can also be optimized according to actual needs to ensure the best sealing effect.
