[0044] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and arrangements of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeatedly refer to numbers and / or letters in different examples, and such repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or arrangements discussed.

[0045] Reference Figure 1 The application provides a mixing and granulating system, which comprises a mixer, a quantitative conveying device and a controller 900.

[0046] The mixer comprises a mixing cylinder 100 and a stirring device (not shown), the mixing cylinder 100 is formed with a mixing cavity, the stirring device extends into the mixing cavity of the mixing cylinder 100, and the stirring device is connected with a driving member, the driving member is used for driving the stirring device to rotate in the mixing cavity, so as to mix the materials in the stirring cavity.

[0047] The mixing cylinder 100 in the mixer can realize the mixing function alone, or can realize the granulating function.

[0048] The mixing and granulating system in the application has the function of quantitatively conveying materials, and the materials in the mixing cavity need to add a curing agent as an adhesive in addition to the raw materials to promote the curing reaction.

[0049] The addition amount of the curing agent is not convenient to control accurately, and the curing agent is corrosive, which can easily pose a safety threat to the operator during the addition process, and the leakage of the curing agent can also corrode the equipment.

[0050] Therefore, the quantitative conveying device involved in the application is mainly aimed at the curing agent with corrosion.

[0051] Specifically, the quantitative conveying device comprises a quantitative pump 200, the quantitative pump 200 is connected with the storage part 300 through a first conveying pipeline 400, and the quantitative pump 200 is connected with the mixing machine through a second conveying pipeline 500.

[0052] In other words, the quantitative pump 200 conveys the curing agent in the storage part 300 to the mixing drum 100 through the first conveying pipeline 400 and the second conveying pipeline 500.

[0053] The quantitative pump 200 is a pump capable of conveying a fixed amount of liquid more accurately, and can ensure that the amount conveyed each time is consistent, thereby ensuring the accurate amount of the curing agent.

[0054] The quantitative pump 200 can be a gear pump, a screw pump, a plunger pump and a diaphragm pump, and the like, and a suitable type of quantitative pump 200 is selected according to the volume of the specific equipment, the required flow, the system pressure and the maintenance requirements and the like.

[0055] The controller 900 is used for realizing intelligent conveying of the curing agent, and specifically, the controller 900 is in signal connection with the quantitative pump 200 and is used for controlling the start and stop of the quantitative pump 200.

[0056] That is, the target conveying amount of the curing agent is input in advance in the controller 900, then the controller 900 monitors the quantitative pump 200 in real time, and when the conveying amount of the quantitative pump 200 reaches the target conveying amount of the curing agent, the controller 900 stops the quantitative pump 200.

[0057] In some embodiments of the present application, a safety valve 510 is arranged on the second conveying pipeline 500 downstream of the quantitative pump 200, and the safety valve 510 is connected with the storage part 300 through a backflow pipe.

[0058] The safety valve 510 is in a normally closed state, when the pressure in the second conveying pipeline 500 exceeds a specified value, the safety valve 510 is opened, and part of the curing agent is discharged through the backflow pipe, and the other end of the backflow pipe is connected with the storage part 300 to recover the curing agent.

[0059] The safety valve 510 prevents the pressure in the second conveying pipeline 500 from exceeding the specified value by discharging the curing agent to the outside of the system, so as to control the pressure in the pipeline to not exceed the specified value, which plays an important protection role for personal safety and equipment operation.

[0060] In addition, in some embodiments of the present application, a sampling pipeline 541 is further arranged on the second conveying pipeline 500, the sampling pipeline 541 and the second conveying pipeline 500 are connected through a three-way piece 540, and a sampling on-off valve 542 is arranged on the sampling pipeline 541.

[0061] The sampling pipeline 541 is used for the operator to sample and detect the curing agent, so as to ensure the quality of the curing agent and whether the curing agent parameters meet the regulations.

[0062] When the curing agent needs to be detected, the operator opens the sampling switch valve 542, and part of the curing agent is output from the sampling pipeline, so as to facilitate the operator to sample.

[0063] The pulse damper 520 is further arranged on the second conveying pipeline 500, which is used to eliminate the liquid pressure pulsation or flow pulsation in the second conveying pipeline 500, stabilize the fluid pressure and flow, eliminate the pipeline vibration, and protect the downstream instruments and equipment.

[0064] The back pressure valve 530 and the flow sensor 560 are further arranged on the second conveying pipeline 500. The back pressure valve 530 is used to further maintain the stability of the system pressure, and ensure the smoothness of the curing agent fluid flowing in the pipeline. The flow sensor 560 is used to measure the flow of the fluid, and convert the measured results into an electrical signal or other form of output, so as to facilitate control and monitoring.

[0065] In addition, the check valve 550 and the electromagnetic switch valve 570 are further arranged on the second conveying pipeline 500. The check valve 550 is used to avoid backflow of the curing agent in the second pipeline, and the electromagnetic switch valve 570 is used to control the opening and closing of the second conveying pipeline 500.

[0066] Reference Figure 2 In some embodiments of the present application, in order to facilitate the output of the curing agent from the supply cylinder 620 to the storage part 300, the present application is provided with a feeding assembly, which comprises a self-priming pump 600 and a liquid supply pipe 610. The liquid supply pipe 610 is connected with the storage part 300, and the self-priming pump 600 is connected with the liquid supply pipe 610. The self-priming pump 600 is used to supplement the material in the storage part 300.

[0067] The end size of the liquid supply pipe 610 is matched with the opening size of the supply cylinder 620. Generally, the weight of the curing agent in the supply cylinder 620 is 25-50 kg, and the capacity of the storage part 300 is about 200-250 kg. After the liquid supply pipe 610 completes the delivery of the curing agent in one supply cylinder 620, the operator closes the self-priming pump 600, and replaces the end of the liquid supply pipe 610 to other supply cylinder 620, so as to store more curing agent in the storage part, and meet the demand of the curing agent in the mixing and granulation process.

[0068] The first liquid level sensor 310 is located at a lower position in the storage cavity, which is used to monitor the preset lower limit of the liquid level of the material in the storage cavity. The second liquid level sensor 320 is located above the first liquid level sensor 310, which is used to monitor the preset upper limit of the liquid level of the material in the storage cavity.

[0069] The controller 900 is connected with the first liquid level sensor 310, the second liquid level sensor 320 and the self-suction pump 600, and the controller 900 controls the start and stop of the self-suction pump 600 according to the delivered liquid level signal of the first liquid level sensor 310 or the second liquid level sensor 320.

[0070] The controller 900 monitors in real time through the first liquid level sensor 310 and the second liquid level sensor 320, and when the self-suction pump 600 inputs the curing agent into the storage cavity to the upper limit of the preset liquid level corresponding to the second liquid level sensor 320, the controller 900 controls the self-suction pump 600 to stop and stop delivering the curing agent into the storage cavity.

[0071] With the progress of the mixing and granulation, the curing agent in the storage part 300 is continuously delivered into the mixing cylinder 100, and when the liquid level of the curing agent in the storage cavity drops to the lower limit of the preset liquid level corresponding to the first liquid level sensor 310, the controller 900 sends a liquid supply signal to remind the operator to start the self-suction pump 600 to supplement the curing agent into the storage part 300.

[0072] That is, the stop of the self-suction pump 600 can be directly controlled by the controller 900, and the start of the self-suction pump 600 is manually started by the operator through the prompt signal sent by the controller 900, and the connection of the end of the liquid supply pipe 610 and the liquid supply cylinder 620 is checked.

[0073] The top of the liquid storage part is also provided with an exhaust pipe 330 for balancing the air pressure inside and outside the liquid storage part.

[0074] In some other embodiments of the present application, due to the arrangement of the safety valve 510 and the sampling pipeline 541, the amount of the curing agent pumped into the mixing cavity by the quantitative pump 200 has a deviation.

[0075] Reference Figure 3 In order to further improve the accuracy of the curing agent delivered into the mixing cavity, the present application further provides a calibration device between the quantitative pump 200 and the storage part 300, and the transfer device is specifically arranged downstream of the safety valve 510 and the sampling pipeline 541.

[0076] The calibration device includes a weighing part 800 and a temporary storage part 820 located on the weighing part 800, and the weighing part 800 can be a weighing tool such as a weight sensor or an electronic scale, and the weighing part 800 is used to weigh the weight of the material in the temporary storage part 820.

[0077] The temporary storage part 820 is connected with the storage part 300 through a first branch pipe 821 and connected with the quantitative pump 200 through a second branch pipe 823, and the first branch pipe 821 is provided with a first pump body 822, and the first pump body 822 is used to deliver the material in the storage part 300 into the temporary storage part 820.

[0078] That is, the quantitative pump 200 pumps the curing agent into the temporary storage 820 through the second branch, and thus the weight of the curing agent in the temporary storage 820 is the final weight after the safety valve 510 and the sampling pipeline, and is also the amount of the curing agent finally input into the mixing cavity.

[0079] The controller 900 is connected with the first pump body 822 and the weighing device 800, the weighing device 800 transmits the weight signal of the material in the temporary storage 820 to the controller 900, and the controller 900 controls the quantitative pump 200 and the first pump body 822 to switch.

[0080] Firstly, the controller 900 controls the quantitative pump 200 to pump the preset curing agent into the temporary storage 820, and the weight of the curing agent is checked again by the weighing device 800 to see whether it is the target weight G. When the amount of the curing agent in the temporary storage 820 is less than the target weight, it means that part of the curing agent is input back into the storage 300 through the safety valve 510 and the return pipeline or is sampled from the sampling pipeline 541. At this time, the controller 900 calculates the weight difference AG according to the actual weight G1 obtained by the weighing device 800 and the target weight, and the weight difference AG satisfies AG=G-G1. Then the quantitative pump 200 is started again to input the curing agent with the weight of AG into the temporary storage 820 until the curing agent in the temporary storage 820 reaches the target weight G.

[0081] In combination with Figure 4 In some embodiments of the present application, the mixing and granulating system further comprises a liquid receiving tray 700, and the storage 300, the quantitative pump 200 and the calibration device are fixed at the bottom of the liquid receiving tray 700.

[0082] Specifically, the storage 300 is supported at the bottom of the liquid receiving tray 700 through the first supporting leg 710, the quantitative pump 200 is supported at the bottom of the liquid receiving tray 700 through the second supporting leg 720, and the weighing device 800 in the calibration device is supported at the bottom of the liquid receiving tray 700 through the supporting table 810.

[0083] The water receiving tray is used to collect the curing agent flowing out due to pipeline damage, connection leakage and the like. The discharge device, the quantitative pump 200 and the calibration device are supported above the water receiving tray through the supporting leg or the supporting table 810 and are isolated from the water receiving tray, so that the curing agent corrosion can be avoided, the safety hidden danger can be reduced, and the economic loss can be avoided.

[0084] In the description of the above embodiments, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0085] The above merely is the specific implementation manner of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application, therefore, the protection scope of the present application should be subject to the protection scope of the claims.
