Description

Technical Field

[0001] The utility model relates to the technical field of the intermediate production system of carbon products, in particular to an intensive kneading pot negative pressure measurement and control system. Background Art

[0002] The kneading pot is one of the most core devices in the intermediate production link of carbon products. Quality is the foundation for an enterprise's survival. At present, the dust removal negative pressure of the kneading system in the forming workshop is not only to ensure the cleanliness of the on-site working link, but also fatal to the process. If the negative pressure is too small, it will lead to unsmooth feeding and discharging of the kneading pot, which will not only affect the production efficiency, but also cause material accumulation, affecting the batching quality. If the negative pressure is too large, the required components in the material will be sucked away, resulting in out-of-control material ratio and out-of-control material temperature, and ultimately a batch of defective products. Therefore, the negative pressure intensity of the kneading system must be ensured within the process requirements. At present, the method for adjusting the negative pressure of the kneading system in the workshop is to install a mechanical pressure gauge at the pressure measurement point and manually observe and adjust the negative pressure valve to adjust the pressure of each kneading pot. When some changes occur in the dust collector, resulting in negative pressure changes, it is impossible to observe in time and even more impossible to adjust in time. Therefore, defective products are often produced.

[0029] See Figure 1 as shown

[0030] This embodiment discloses an intensive kneading kettle negative pressure measurement and control system, which includes

[0031] Negative pressure detection system 1 and negative pressure regulation system 2

[0032] The negative pressure detection system 1 is connected to the negative pressure detection port of each kneading kettle 3 of the kneading kettle system through a negative pressure detection pipeline. The negative pressure detection system 1 has a negative pressure detection box 103, and a negative pressure induction pressure gauge is configured in the negative pressure detection box 103

[0033] The negative pressure regulation system 2 is connected to the negative pressure regulation port of each kneading kettle 3 through a negative pressure pipe network

[0034] Each kneading kettle 3 is provided with a negative pressure switch valve 203. When the kneading kettle 3 feeds and discharges materials, the corresponding negative pressure switch valve 203 is opened

[0035] Specifically, this embodiment discloses an intensive kneading kettle negative pressure measurement and control system, which is divided into two parts: a negative pressure detection system 1 and a negative pressure regulation system 2. Among them, the negative pressure detection box 103 of the negative pressure detection system 1 is connected to each kneading kettle 3 through a negative pressure detection pipeline, and monitors the negative pressure state and value of each kneading kettle 3 during the working state respectively. Each kneading kettle 3 of this embodiment is connected with a negative pressure switch valve 203. The negative pressure switch valve 203 is only used when the kneading kettle 3 feeds and discharges materials, and each kneading kettle 3 feeds and discharges materials one by one each time. Therefore, the negative pressure pipe network can be used to connect with each kneading kettle 3 for negative pressure regulation. A high-precision intelligent negative pressure induction pressure gauge is configured in the negative pressure detection box 103 of the negative pressure detection system 1 of this embodiment, which is mainly used to detect the negative pressure intensity in each kneading kettle 3 respectively

[0036] Preferably, the kneading pot 3 of this embodiment is connected to the negative pressure detection bus 101 of the negative pressure detection system 1 through the negative pressure detection branch line 102; among them, multiple negative pressure detection branch lines 102 of this embodiment are connected in parallel with each other;

[0037] The negative pressure detection bus 101 is connected to the negative pressure detection box 103.

[0038] Secondly, in the system of this embodiment, a vacuum solenoid valve 104 is installed on the negative pressure detection branch line 102 connected to each kneading pot 3;

[0039] The negative pressure detection box 103 has a negative pressure detection bypass branch line, and a vacuum solenoid valve 104 is installed on the negative pressure detection bypass branch line. The vacuum solenoid valve 104 of the negative pressure detection box 103 is communicated with the atmosphere through a pipeline.

[0040] This embodiment further defines the composition of the negative pressure detection system 1. First, the negative pressure detection system 1 of this embodiment is composed of a negative pressure detection bus 101 and several negative pressure detection branch lines 102. Each negative pressure detection branch line 102 is connected to a kneading pot 3. A vacuum solenoid valve 104 is installed at the negative pressure detection port of each kneading pot 3. The inlet and outlet of the vacuum solenoid valve 104 are connected to the negative pressure detection box 103 of the negative pressure detection bus 101 through the negative pressure detection branch line 102. A vacuum solenoid valve 104 is also installed at the detection port of the negative pressure detection box 103 of this embodiment, and the vacuum solenoid valve 104 is communicated with the atmosphere, which is used to release the pressure of the detection pipeline and clean the pipeline. When a certain kneading pot 3 needs to feed and discharge materials, the corresponding vacuum solenoid valve 104 of the kneading pot 3 is opened to perform a negative pressure test on the kneading pot 3. The vacuum solenoid valve 104 at the negative pressure detection box 103 is opened for 5 seconds at the beginning and end of each detection, and the pipeline is purged and the pressure is released to facilitate more accurate testing next time.

[0041] Preferably, the kneading pot 3 of this embodiment is connected to the negative pressure pipe network bus 201 of the negative pressure regulation system through the negative pressure pipe network branch line 202; multiple negative pressure pipe network branch lines 202 are connected in parallel with each other.

[0042] Secondly, in the system of this embodiment, a negative pressure regulating valve 204 and a negative pressure switch valve 203 are installed on the negative pressure pipe network branch line 202 connected to each kneading pot 3.

[0043] In this embodiment, a negative pressure regulating valve 204 is installed above the negative pressure switch valve 203 of the negative pressure pipeline of each kneading kettle 3. When testing the negative pressure of the kneading kettle 3, the actual negative pressure value of the kneading kettle 3 is compared with the negative pressure value required by the process. If it is not within the range of the process value, the system will automatically send an instruction to the intelligent negative pressure regulating valve 204 to track and adjust the negative pressure of the kneading kettle 3, so that the negative pressure can always meet the process requirements, ensure the stability of the material and the material of each kettle can meet the qualified standard. Moreover, the negative pressure adjustment and monitoring do not require manual intervention and are automatically completed by the system.

[0044] In the above technical solution, an intensive kneading kettle negative pressure measurement and control system provided by the present utility model has the following beneficial effects:

[0045] The negative pressure measurement and control system of the present utility model can centrally monitor the negative pressure of all kneading kettles 3 and discretely control the negative pressure intensity of each kneading kettle 3 according to the process requirements.

[0046] The negative pressure measurement and control system of the present utility model realizes automatic detection and adjustment of the negative pressure of each kettle of material, ensuring the quality of each product. The intelligent control using PLC does not require manual intervention, saving labor costs and management costs, improving the stability of the equipment, preventing the generation of batch waste products, improving the reasonable utilization rate of negative pressure, and avoiding negative pressure waste.

[0047] Only some exemplary embodiments of the present utility model have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways.
