Description

Technical Field

[0001] This application relates to the technical field of isostatic graphite production, and in particular to an isostatic graphite production system. Background Technology

[0002] In the existing isostatic pressing process, the graphite is cooled directly after kneading. However, the kneading process is achieved by heating and stirring, which makes the material into a paste. Direct cooling is less effective and results in a longer production time. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, one of the objectives of this application is to provide an isostatic graphite production system, which has the advantages of better cooling effect on the paste and shorter cooling time.

[0004] The above-mentioned objective of this application is achieved through the following technical solution: An isostatic pressing graphite production system includes a plate forming module and a cooling module. The plate forming module is used to press the paste into thin sheets, and the cooling module is used to cool the sheet-shaped paste.

[0005] By adopting the above technical solution, in the production process, the paste is pressed into thin sheets and cooled by a cooling device, which can effectively improve the cooling effect of the paste and shorten the cooling time.

[0006] In a preferred embodiment, the present application may be further configured such that the forming module includes a pressing roller and a pressing plate, the pressing plate having a plurality of through holes.

[0007] By adopting the above technical solution, during pressing, some of the paste will be discharged from the through hole under the action of the pressing roller, thereby further improving the cooling effect of the paste.

[0008] In a preferred embodiment, the present application may be further configured such that: the cooling module includes a negative pressure cooling cylinder, the negative pressure cooling cylinder is provided with an air outlet and an air inlet, the air outlet is connected to a negative pressure device, and the air inlet is used to allow cooling gas to enter into the negative pressure cooling cylinder.

[0009] By adopting the above technical solution, during use, both the plate-shaped paste and the paste discharged from the through hole are put into the negative pressure cooling cylinder. Then, by making the negative pressure cooling cylinder negative pressure and introducing cooling gas into the negative pressure cooling cylinder, the paste is cooled, thereby achieving a better cooling effect on the paste.

[0010] In a preferred embodiment, the present application may be further configured such that the cooling module further includes a rolling mechanism, the negative pressure cooling cylinder is placed on the rolling mechanism and is driven to rotate by the rolling mechanism.

[0011] By adopting the above technical solution, the negative pressure cooling cylinder rotates under the drive of the rolling mechanism, causing the paste inside the negative pressure generating cylinder to move, thereby improving the cooling effect on the material.

[0012] In a preferred embodiment, this application may be further configured to include a temperature measurement module, a control module, and a notification module. The temperature measurement module is used to detect the temperature t1 at the air outlet and the temperature t2 at the air inlet. The control module queries the temperature detected by the temperature measurement module and compares the temperature at the air outlet with the temperature at the air inlet. If the difference is within a preset range, a discharge signal is sent to the notification module. After receiving the discharge signal, the notification module issues a discharge notification.

[0013] By adopting the above technical solution, during use, by comparing temperature t1 and temperature t2, when the difference is within the preset range, it indicates that cooling is complete and material can be discharged. Therefore, the discharge notification is sent through the notification module.

[0014] In a preferred embodiment, this application may be further configured to include a timing module, which sends a query signal to the control module after time T, and the control module performs a temperature query after receiving the query signal.

[0015] By adopting the above technical solution, the paste is expected to cool down after time T. Therefore, the timing module sends a query signal to the control module, and the control module queries the temperature, thereby making the cooling control of the paste more precise.

[0016] In a preferred embodiment, this application may be further configured to include a pressure module for detecting the pressure inside the negative pressure cooling cylinder. The control module reads the pressure detected by the pressure module and compares it with a standard value. If the pressure is greater than the standard value, the control module sends a pressure signal to the notification module. Upon receiving the pressure signal, the notification module issues a pressure anomaly warning.

[0017] By adopting the above technical solution, the presence of a pressure detector during use enables the detection of pressure inside the negative pressure cooling cylinder, and timely notification of pressure changes can be provided when pressure changes occur.

[0018] In a preferred embodiment, this application may be further configured to include an external temperature module for detecting the temperature t3 of the paste sent into the negative pressure cooling cylinder. The control module reads the temperature detected by the external temperature module and compares it with a standard value. If the temperature differs from the standard value, a cooling signal is sent to the notification module. Upon receiving the cooling signal, the notification module provides a preliminary cooling anomaly alert.

[0019] By adopting the above technical solution, the temperature t3 is detected during use. When it does not meet the standard value, it indicates an abnormality, and therefore a warning needs to be issued. Attached Figure Description

[0024] The present application will be further described in detail below with reference to the accompanying drawings.

[0025] Reference Figures 1-3 The present application discloses an isostatic pressing graphite production system, which includes a plate forming module, a cooling module, a temperature measuring module 4, a control module 5, a notification module 6, a timing module 7, a pressure module 8, and an external temperature module 3.

[0026] The forming module is used to press the paste into thin sheets, and the cooling module is used to cool the sheet-like paste. The forming module includes a pressing roller and a pressing plate, with several through holes on the pressing plate. The paste is placed on the pressing plate and pressed by the pressing roller, causing the paste to be pressed into thin sheets, with some paste being extruded through the through holes.

[0027] The cooling module includes a negative pressure cooling cylinder 2 and a rolling mechanism. The rolling mechanism includes a support frame 11 with rotating rollers 12 arranged in a V-shape to support the negative pressure cooling cylinder 2. The rotating rollers 12 are driven to rotate by a motor, and their axis is parallel to the axial direction of the negative pressure cooling cylinder 2. One end of the negative pressure cooling cylinder 2 has an outlet 22, and the other end has an inlet 21. The outlet 22 is connected to a negative pressure device (e.g., an exhaust fan) via a rotary joint, and the inlet 21 is connected to a pipe via a rotary joint to allow cooling gas to enter the negative pressure cooling cylinder 2. Both the outlet 22 and the inlet 21 are equipped with solenoid valves. The negative pressure cooling cylinder 2 also has ribs 23 arranged along its axial direction.

[0028] During use, the paste is fed into the negative pressure cooling cylinder 2, and air is drawn out of the cylinder 2 by a negative pressure device. The extracted gas is blown toward the paste that is squeezed out from the through hole, which cools and breaks the paste. Cooling gas enters the negative pressure cooling cylinder 2 through the air inlet 21 for further cooling of the paste.

[0029] During the cooling process, the negative pressure cooling cylinder 2 rotates, and the ribs 23 move the paste. First, cooling gas is introduced into the negative pressure cooling cylinder 2, maintaining a positive pressure state for a period of time. Then, the negative pressure equipment evacuates the air, maintaining a negative pressure state for a period of time. In the first half of the evacuation phase, cooling gas is continuously introduced; in the second half, the introduction of cooling gas stops. The amount of cooling gas entering per unit time is less than the amount of air evacuated per unit time. Within a single cooling cycle, the positive pressure phase and the negative pressure phase alternate.

[0030] Temperature measurement module 4 is used to detect the temperature t1 at the air outlet 22 and the temperature t2 at the air inlet 21. Timing module 7 sends a query signal to control module 5 after time T. Control module 5, upon receiving the query signal, performs a temperature query. Control module 5 queries the temperature detected by temperature measurement module 4 and compares the temperature t1 at the air outlet 22 with the temperature t2 at the air inlet 21. If the difference is within a preset range, it sends a discharge signal to notification module 6. Notification module 6, upon receiving the discharge signal, issues a discharge notification.

[0031] Pressure module 8 is used to detect the pressure inside the negative pressure cooling cylinder 2. Control module 5 reads the pressure detected by pressure module 8 in real time and compares it with the corresponding standard value. If it exceeds the standard value, control module 5 sends a pressure signal to notification module 6. Notification module 6, upon receiving the pressure signal, issues a pressure anomaly warning. In this application, the duration of a single cooling cycle is used as the horizontal axis, and the pressure corresponding to that duration is used as the vertical axis, thus establishing a correspondence between time and pressure. When control module 5 reads the pressure measured by pressure module 8 in real time, it obtains the cooling duration of the current cooling cycle and compares it with the corresponding pressure standard value.

[0032] The external temperature module 3 is used to detect the temperature t3 of the paste fed into the negative pressure cooling cylinder 2 and the ambient temperature t4. The control module 5 reads the temperature t3 detected by the external temperature module 3 and compares it with the standard value. If it differs from the standard value, a cooling signal is sent to the notification module 6. Upon receiving the cooling signal, the notification module 6 provides a preliminary cooling anomaly warning. That is, during production, because the paste is pressed into a plate shape and extruded from the through holes, it can achieve a certain cooling effect. Therefore, when the temperature of the paste entering the negative pressure cooling cylinder 2 does not meet the standard, it indicates that there is a problem with the preliminary cooling and it needs to be addressed.

[0033] The implementation principle of this embodiment is as follows: In production, the paste is pressed into a plate shape, and during the pressing process, some of the paste is discharged from the through hole and becomes granular under the action of wind. The plate-shaped paste and the granular paste are put into the negative pressure cooling cylinder 2. Under the action of negative pressure and cooling airflow, the material is cooled, thereby achieving a better cooling effect.

[0034] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
