Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of carbon black production, in particular to a carbon black product re-adding device. Background Art
[0002] In the carbon black industry, there are carbon black products that are returned by customers, and these products need to be reprocessed to avoid waste and the formation of hazardous waste. Traditional carbon black product return devices include sealed ton bag unpacking machines, which mainly include an electric hoist, a sealed box with a sealed door on its side, a recovery funnel, and a negative pressure conveying pipeline. The sealed box, recovery funnel, and negative pressure conveying pipeline are connected and arranged in sequence from top to bottom. When in use, the ton bag is transferred to the sealed box through the electric hoist through the sealed door. The operator then reaches in and unties the binding rope on the ton bag, allowing the material in the ton bag to slide into the recovery funnel, and finally transports the material to the next process through the negative pressure conveying pipeline. However, the moment the operator unties the binding rope, carbon black dust will be generated, polluting the working environment and causing the operator to inhale carbon black dust, resulting in respiratory injuries.
[0003] In order to minimize the leakage of carbon black dust during the carbon black re-addition process, a dust suction fan and a pulse bag filter are added to the existing carbon black product re-addition device. The fan inlet of the dust suction fan is connected to the sealed box, the fan outlet of the dust suction fan is connected to the inlet of the pulse bag filter, and the outlet of the pulse bag filter is connected to the negative pressure conveying pipe. When in use, the floating carbon black dust is adsorbed by the dust suction fan and transported to the pulse bag filter, and the gas-solid separation is carried out through the filter bag of the pulse bag filter. The separated solid powder enters the negative pressure conveying pipe again for recycling and treatment. Although the carbon black product re-addition device can effectively avoid the leakage of carbon black dust during the carbon black re-addition process, the subsequent maintenance cost of the device is relatively high. For example, during subsequent maintenance, compressed air medium needs to be added to regularly back-blow the pulse bag filter, and the discarded filter bags also need to be treated as hazardous waste. Summary of the Invention
[0004] In order to solve the problem of high later maintenance cost of the existing carbon black product re-adding device, the utility model provides a new carbon black product re-adding device.
[0005] The utility model is realized by adopting the following technical solutions:
[0006] A carbon black product recycling device includes a ton bag unpacking machine, which includes an electric hoist, a sealed box with a sealed door on its side, a recovery funnel, and a negative pressure conveying pipeline. The upper end of the sealed box is provided with an air supply inlet pipe, and the lower end of the sealed box is provided with an air supply outlet pipe. The air supply port of the negative pressure conveying pipeline is sealed and connected to the air supply outlet pipe of the sealed box.
[0007] Principle explanation: Since the sealed box itself is closed, it only needs to maintain a slight negative pressure as a whole. At the same time, the negative pressure conveying pipeline itself requires a large amount of air volume. Therefore, the air volume required by the negative pressure conveying pipeline is combined with the dust collection air volume required by the sealed box, so that the air flow rate inside the sealed box is accelerated, and the carbon black powder generated during the untying of the strapping ropes on the ton bags enters the negative pressure conveying pipeline as quickly as possible along with the air entering from the supplementary inlet pipe, effectively preventing the carbon black powder from floating and ensuring the safety of the working environment of the operators.
[0008] Furthermore, a single suction valve is provided at the air supply inlet pipe, so that when pressure fluctuations occur in the negative pressure delivery pipeline, the sealed box can serve as a buffer container, so that carbon black powder will not spill into the working environment, further ensuring the safety of the working environment of the operators.
[0009] The beneficial effects produced by the present invention are as follows: 1) The device described in the present invention eliminates the pulse bag filter, avoids the generation of hazardous waste of discarded filter bags, and reduces the subsequent maintenance cost of the device; 2) The device described in the present invention eliminates the dust suction fan, reducing the manufacturing cost of the device; 3) The device described in the present invention cleverly utilizes the characteristic that the negative pressure conveying pipeline itself needs to be replenished with air, and by setting the replenishing air port on the sealed box body, the carbon black dust floating in the sealed box body is driven into the negative pressure conveying pipeline, thereby avoiding the overflow of carbon black dust, and no longer needing to be collected by the pulse bag filter.

It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0018] like Figure 1 As shown, a carbon black product recycling device includes a ton bag unpacking machine, which includes an electric hoist 2, a sealed box 3 with a sealed door 4 on its side, a recovery funnel 5, and a negative pressure conveying pipe 6. The upper end of the sealed box 3 is provided with an air supply inlet pipe 7, and the lower end of the sealed box 3 is provided with an air supply outlet pipe 8. The air supply port of the negative pressure conveying pipe 6 is sealed and connected with the air supply outlet pipe 8 of the sealed box 3.
[0019] Principle explanation: Since the sealed box 3 itself is closed, the whole body only needs to maintain a slight negative pressure. At the same time, the negative pressure conveying pipe 6 itself requires a large amount of air volume. Therefore, the air volume required by the negative pressure conveying pipe 6 is combined with the dust collection air volume required by the sealed box 3, so that the air flow rate inside the sealed box 3 is accelerated, so that the carbon black powder generated during the untying of the binding rope on the ton bag 1 enters the negative pressure conveying pipe 6 as quickly as possible along with the air entering from the supplementary inlet pipe, effectively avoiding the overflow of carbon black powder and ensuring the safety of the working environment of the operators.
[0020] During specific implementation, a single suction valve 9 is provided at the air supply inlet pipe 7, so that when pressure fluctuations occur in the negative pressure delivery pipeline 6, the sealed box 3 can serve as a buffer container, so that the carbon black powder will not spill into the working environment, further ensuring the safety of the working environment of the operators.
