[0002] After carbon black is processed, the finished product needs to be stored in storage tanks. Carbon black storage requires a suitable storage environment with appropriate temperature and humidity. However, in some areas, the temperature in warehouses or workshops is too high or too low during summer or winter, which can be transmitted to the carbon black through the storage tanks, thus affecting the storage quality of the carbon black. For example, Chinese utility model patent with publication number CN215754302U discloses a moisture-proof silo for processing red carbon black, including a silo body. A vacuum groove is opened at the edge of the inner wall of the silo body. Insulation strips are fixed on both sides of the inner wall of the vacuum groove. A support ring is fitted at the bottom of the outer wall of the silo body. Four support columns are fixed at equal intervals at the bottom of the support ring. A threaded ring is fixed at the middle position of the bottom of the silo body.

[0003] The above technical solution does not include a structure for regulating storage temperature. Moreover, when storing carbon black, if the amount of carbon black to be stored is large, a large number of storage tanks are required, which increases the cost of use. If a device for regulating storage temperature is used, it will also cause unnecessary energy waste. Sometimes, if the amount of carbon black to be stored is small, the existing storage silos or storage tanks cannot adjust their volume according to the amount of storage, resulting in a waste of the space used by the storage tanks or silos.

[0004] Therefore, how to add temperature regulation function to carbon black storage silos and adjust the volume of storage silos according to the amount of carbon black stored is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

Detailed Implementation

[0029] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0030] The core of this invention is to provide a carbon black storage silo to improve the effective load-bearing capacity of the carbon black storage silo.

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] Please refer to Figures 1 to 9This utility model discloses a carbon black storage silo, including a silo body 1, a silo cover 2, and a silo bottom 3; the silo body 1, silo cover 2, and silo bottom 3 are combined to form a cylindrical storage silo structure. Multiple silo bodies 1 can be connected end-to-end and disassembled to form storage silos of different volumes. The side wall of the silo body 1 is provided with a heat insulation structure layer 101 and a temperature regulating coil 102. The temperature regulating coil 102 is located inside the heat insulation structure layer 101 and is connected to an inlet pipe 103 and an outlet pipe 104. 03 is located below the outlet pipe 104. Both the inlet pipe 103 and the outlet pipe 104 extend outward through the side wall of the silo body 1 and are connected to a temperature regulating source (not shown in the figure). The temperature regulating source is a water tank, which stores hot or cold water. Different media are selected according to the temperature regulation requirements to supply water flow into each temperature regulating pipe 102. The silo cover 2 is used to cover the top of the silo body 1 and is sealed to the silo body 1. The silo bottom 3 is connected to the bottom of the silo body 1. The silo bottom 3 is provided with a discharge port 301. The silo bottom 3 is used for storage support and discharge.

[0033] The working process and principle of the above structure are as follows:

[0034] In use, multiple silos 1 are pre-assembled to form a complete storage silo body according to the amount of carbon black to be stored. Then, the assembled silos 1 are installed on the silo bottom 3, and carbon black material is added into the silos 1. After the material is filled, the silo cover 2 is placed on the silos 1 to realize the storage operation of carbon black material. The inlet pipe 103 and outlet pipe 104 on each silo 1 are connected to the temperature control source. The temperature control medium enters the temperature control coil to maintain and regulate the temperature of the carbon black material in the silo 1, ensuring that the temperature in the silo 1 is within a suitable range. The setting of the heat insulation structure layer 101 can minimize the impact of the external ambient temperature on the temperature inside the storage silo. The dual measures ensure the storage environment of carbon black in the silo. The detachable and combinable structure of the silos can adjust the number of silos installed according to the amount of carbon black stored, thereby eliminating the need for multiple storage tanks to be used at the same time and reducing storage costs.

[0035] In another embodiment of this utility model, based on embodiment 1, as follows: Figure 1 As shown, a desiccant inlet hole 105 is provided on the silo body 1. A one-way valve can be hinged to the inner port of the desiccant inlet hole 105. The desiccant inlet hole 105 has an internal thread. A desiccant insertion device 4 is connected to the desiccant inlet hole 105 through the thread. When the desiccant insertion device 4 is inserted, it opens the one-way valve. When the desiccant insertion device 4 is removed, the one-way valve falls down to prevent carbon black material from flowing out.

[0036] The carbon black material in the chamber 1 is dried by inserting a desiccant into the device 4, which avoids moisture affecting the quality of the carbon black. The threaded connection makes disassembly and assembly more convenient and ensures airtightness.

[0037] In another embodiment of this utility model, based on embodiment 1, as follows: Figure 3 As shown, the desiccant insertion device 4 includes a pull-out cover 401, a connecting tube 402, and a filter tube 403. One end of the connecting tube 402 is tapered, and the other end is detachably connected to the pull-out cover 401. The pull-out cover 401 is provided with an external thread that mates with the internal thread of the desiccant inlet hole 105. The filter tube 403 is disposed inside the connecting tube 402, and the outer wall of the filter tube 403 is tightly fitted with the inner wall of the connecting tube 402. The filter tube 403 has filter mesh openings, and desiccant is disposed inside the filter tube 403. The connecting tube 402 has multiple drying ports 404 that expose the filter tube 403.

[0038] When the desiccant insertion device 4 is installed, the tapered end of the connecting tube 402 passes through the desiccant inlet hole 105 and is inserted into the carbon black material in the chamber 1. The tapered end reduces the piercing resistance, making it easier to insert the connecting tube 402. After the connecting tube 402 is fully inserted into the chamber 1, the desiccant insertion device 4 is fixed by the threaded engagement of the pull-out cover 401 with the desiccant inlet hole 105. The desiccant in the filter tube 403 comes into contact with the carbon black adsorbed on the filter mesh through the drying port 404, thereby achieving the adsorption and drying treatment of moisture in the carbon black product by the desiccant. At the same time, after the temperature regulating coil 102 heats the carbon black material, the moisture in the carbon black material floats upward and can be adsorbed by the desiccant insertion device 4 inserted into the carbon black material, thereby achieving the storage and drying of the carbon black material.

[0039] In another embodiment of this utility model, based on embodiment 1, as follows: Figure 3 As shown, the pull-out cover 401 includes an integrally formed cover plate 4011 and a threaded sleeve 4012. The cover plate 4011 has a circular plate structure. The external thread on the pull-out cover 401 is provided on the threaded sleeve 4012. A handle 4013 is provided on the end face of the cover plate 4011 away from the threaded sleeve 4012. The connecting tube 402 is sleeved in the threaded sleeve 4012. The connecting tube 402 and the threaded sleeve 4012 are respectively provided with pin holes. The connecting tube 402 and the threaded sleeve 4012 are connected by a pin 4014.

[0040] The desiccant insertion device 4 is fixed by connecting the external thread on the threaded sleeve 4012 with the internal thread of the desiccant inlet hole 105. The handle 4013 facilitates manual operation of the pull-out cover 401, making it easier to take out the desiccant insertion device 4. The rotating pull-out cover 401 also provides a point of leverage. The connecting pipe 402 and the threaded sleeve 4012 are connected together by a pin 4014, making disassembly and assembly easier and facilitating the subsequent addition of desiccant to the filter tube 403.

[0041] In another embodiment of this utility model, based on embodiment 1, as follows: Figures 1-9 As shown, the top of the chamber 1 is provided with a first threaded tube 106 with external threads. The outer diameter of the first threaded tube 106 is smaller than the outer diameter of the chamber 1.

A first mounting groove 109 is provided on the inner side of the bottom of the chamber 1. An internal thread is provided on the inner wall of the first mounting groove 109 to engage with the first threaded tube 106. A first sealing groove 1092 is provided at the bottom of the first mounting groove 109 to fit into the first sealing ring 107. A second sealing ring 1091 is provided in the first sealing groove 1092.

[0042] The storage hopper can be quickly disassembled and assembled by threading the first threaded pipe 106 of the hopper body 1 to the first mounting groove 109 of another hopper body 1 or the second mounting groove 201 of the hopper cover 2. A sealed connection is achieved by the cooperation of the first sealing ring 107 with the first sealing groove 1092 of another hopper body 1 or the second sealing groove 202 of the hopper cover 2. Further sealing is achieved by the cooperation of the first sealing ring 108 and the second sealing ring 1091, thus enhancing the sealing effect.

[0043] In another embodiment of this utility model, based on embodiment 1, as follows: Figure 4 and Figure 8 As shown, the top of the bin bottom 3 is provided with a second threaded tube 302, which has the same structure as the first threaded tube 106. The end of the second threaded tube 302 is provided with a second sealing ring 303 that matches the diameter of the first sealing groove 1092. A third sealing ring 304 is provided on the second sealing ring 303. The first mounting groove 109 of the bin body 1, which is connected to the bin bottom 3, is threadedly engaged with the second threaded tube 302, and the second sealing ring 303 is embedded in the first sealing groove 1092 of the bin body 1. Both the third sealing ring 304 and the second sealing ring 1091 are rubber sealing rings.

[0044] The second threaded tube 302 facilitates the mating of the top of the bin bottom 3 with the first mounting groove 109 at the bottom of the bin body 1. When the second threaded tube 302 is threaded into the first mounting groove 109, the second sealing ring 303 is also simultaneously inserted into the first sealing groove 1092, achieving a sealed connection between the bin bottom 3 and the bin body 1. The third sealing ring 304 abuts against the second sealing ring 1091, further enhancing the sealing performance.

[0045] In another embodiment of this utility model, based on embodiment 1, as follows: Figure 1 As shown, the lower part of the bin bottom 3 has a conical structure. The discharge port 301 is located at the center of the bottom of the bin bottom 3. A discharge control valve is installed inside the discharge port 301. The discharge control valve can be a manual control valve or a solenoid valve, which is convenient for controlling the opening and closing of the discharge and controlling the discharge amount. Four support legs 305 are provided around the bin bottom 3.

[0046] The tapered bottom 3 facilitates automatic centralized material unloading, and the support legs 305 prevent the bottom 3 from directly contacting the ground.

[0048] The second mounting groove 201 facilitates the connection between the cover 2 and the first threaded tube 106 on the top of the body 1, and also allows the cover 2 to be connected and combined with any body 1, thus ensuring the adaptability and combinability of the body 1. The second sealing groove 202 and the first sealing ring 107 ensure the sealing at the connection between the cover 2 and the body 1. The fourth sealing ring 203 fits with the first sealing ring 108 to further ensure the sealing and prevent moisture from entering. The modular structure allows for immediate replacement if a module malfunctions.

[0049] In another embodiment of this utility model, based on embodiment 1, as follows: Figure 2 As shown, the temperature regulating coil 102 is located inside the side wall of the chamber 1.
