[0012] Preferably, the control ends of the travel switch and the dual-axis motor are electrically connected to an external power supply through a controller and an alarm, so as to facilitate automatic operation and alarm of the device.

[0013] How the device operates:

[0014] Step 1: Installation: The user first fixes the shell, and then puts the elastic seal on the bottom end of the graphite column. The user installs the graphite column inside the shell so that the elastic seal at the bottom end of the graphite column fits with the limiting sleeve. The first positioning sleeve can be used to position the graphite column and control the direction of the cooling hole to be the same as the direction of the discharge pipe.

[0015] Step 2: Positioning installation. The user takes out another set of graphite columns so that the direction of the cooling hole is the same as that of the discharge pipe. At the same time, the positioning blocks at one end of the positioning plate are inserted into the positioning grooves respectively, and the installation is carried out in this way.

[0016] Step 3: Fixing: When the top of the last group of graphite columns is higher than the discharge pipe, put the elastic seal on one end of the graphite column, and then insert the compression sleeve into one end of the shell. Fix the shell, sealing flange, compression sleeve and spring with extended bolts;

[0017] Step 4: Working, the high-temperature material enters the interior of the shell through the first feed pipe, flows upward through the material hole inside the graphite column, and finally discharges the device through the compression sleeve head. At the same time, the low-temperature coolant enters the interior of the shell through the second feed pipe, passes through the cooling hole on the side of the graphite column, and the high-temperature material transfers heat with the graphite column. The graphite column heats up rapidly. At this time, the coolant can quickly transfer heat with the graphite column, and the heated coolant is discharged through the discharge pipe;

[0018] Step 5: Automatic pressure control. The pressure in chamber one or chamber two can be detected through a pressure tube and a pressure gauge. When the pressure in chamber one or chamber two is too high, the pressure pushes the slide rod through the piston to squeeze the travel switch. The travel switch controls the operation of the dual-axis motor. The output end of the dual-axis motor can control the opening range of the ball valve through the worm and worm gear, thereby self-regulating the pressure inside chamber one and chamber two. When the pressure inside chamber one or chamber two returns to a low level, the controller and the dual-axis motor control the worm and worm gear to work in reverse, so that the ball valve is in a normal opening range.

[0019] Step 6: Alarm: If the pressure inside chamber 1 or chamber 2 is too high for a long time, the slider will control the travel switch to open for a long time, and the user will be alerted through the controller and the alarm.

[0020] Step 7: Manual pressure control. The user can control the opening range of the ball valve by turning the handle, and can also protect the device.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] When the user installs this device, the user first fixes the shell, and then puts the elastic seals on the bottom ends of the graphite columns respectively, so that the inner walls of the elastic seals are respectively fitted with the surface of the second positioning sleeves, so that the elastic seals can be limited by the second positioning sleeves, and at the same time, they can be fixed under the elasticity of the elastic seals themselves to prevent the elastic seals from falling off. The user installs a group of graphite columns inside the shell, so that the bottom ends of the graphite columns are located inside the first positioning sleeves, and at the same time, the elastic seals at the bottom ends of the graphite columns are fitted with the limiting sleeves. At this time, the graphite columns can be positioned by the first positioning sleeves, so that the central axis of the graphite columns coincides with the central axis of the shell, and the hole direction of the cooling hole is the same as the hole direction of the discharge pipe, and then the user takes out another set The graphite column makes the direction of the cooling hole the same as that of the discharge pipe, and at the same time makes the positioning blocks at one end of the positioning plate inserted into the inside of the positioning groove respectively, thereby completing the positioning work, and installing in this way until the top of the last group of graphite columns is higher than the discharge pipe. At this time, the user puts the elastic seal on one end of the graphite column, and then the user inserts the compression sleeve head into one end of the shell, and continuously moves it downward until the elastic seal at the top of the graphite column fits with one end of the compression sleeve head. At the same time, the second positioning sleeve is put on the surface of the graphite column, and then the sealing ring is put on the middle of the compression sleeve head. Finally, the user fixes the shell, sealing flange, compression sleeve head and spring by lengthening the bolts, so that the compression sleeve head is provided with pressure under the action of the spring's own elastic force to avoid damage to the graphite column caused by overpressure. At the same time, the elastic seal The components can provide sealing and avoid extrusion between graphite columns, thereby protecting the graphite columns. The user connects and installs the device through bolts, and then connects the device to the controller and alarm through the travel switch and the dual-axis motor. When in use, the high-temperature material enters the interior of the shell through the first feed pipe, flows upward through the material hole inside the graphite column, and finally discharges the device through the compression sleeve. At the same time, the low-temperature coolant enters the interior of the shell through the second feed pipe, and the coolant can be dispersed through the conical diverter plate at one end of the second feed pipe. The coolant passes through the cooling hole on the side of the graphite column, and the high-temperature material transfers heat with the graphite column, and the graphite column heats up rapidly. At this time, the coolant can quickly transfer heat with the graphite column, thereby achieving rapid cooling of the material. The heated coolant is discharged through the discharge pipe. At the same time, the pressure of the coolant in chamber two can be detected through the upper set of pressure pipes and pressure gauges, and the pressure of the material in chamber one can be detected through the lower set of pressure pipes and pressure gauges. When the pressure in chamber one or chamber two is too high, the pressure pushes the piston to slide in the middle of the pressure pipe, and the travel switch can be squeezed through the slide rod. The travel switch controls the operation of the dual-axis motor. The output end of the dual-axis motor can control the opening range of the ball valve through the worm and worm gear, so that the pressure inside chamber one and chamber two can be self-regulated to avoid excessive pressure in chamber one or chamber two, which will cause damage to the graphite column, affect the normal use of the device, or cause damage to the elastic seal, thereby avoiding the risk of leakage.If the pressure in chamber one is too high, it means that the material is discharged excessively. At this time, the opening range of the ball valve is reduced by the dual-axis motor, worm and worm gear to reduce the entry of material, thereby reducing the pressure inside chamber one. If the pressure in chamber two is too high, it means that the coolant is discharged excessively. At this time, the opening range of the ball valve is reduced by the dual-axis motor, worm and worm gear to reduce the entry of coolant, thereby reducing the pressure inside chamber two. When the pressure inside chamber one or chamber two is restored and lowered, under the action of the controller, the output end of the dual-axis motor is controlled to work in reverse, so that the ball valve in the middle of the first feed pipe and the second feed pipe is in the normal opening range. If the pressure inside chamber one or chamber two is too high for a long time If the pressure is too high, and the slide bar controls the travel switch to open for a long time, the controller and alarm will remind the user that the graphite column or elastic seal inside the housing is at risk of damage, so that the user can make the right judgment, thereby protecting the device and extending its service life. If the device cannot automatically adjust the pressure normally, the user can also control the opening range of the ball valve by turning the handle, which can also protect the device. This device is not only convenient for users to install and reduce their work difficulty, but also protects the graphite column and elastic seal, thereby extending their service life. It can also automatically reduce pressure, expand its scope of use, reduce its limitations, and reduce user losses. BRIEF DESCRIPTION OF THE DRAWINGS

The control ends of the travel switch 23 and the dual-axis motor 33 are electrically connected to the external power supply through the controller and the alarm, so that the device can automatically work and alarm.

[0038] The device operates as follows:

[0039] Step 1: Installation. The user first fixes the housing 1, and then sleeves the elastic seal 5 on the bottom end of the graphite column 4. The user installs the graphite column 4 inside the housing 1 so that the elastic seal 5 at the bottom end of the graphite column 4 fits with the limiting sleeve 2. The first positioning sleeve 3 can be used to position the graphite column 4, and the direction of the cooling hole 16 is controlled to be the same as that of the discharge pipe 14.

[0040] Step 2: Positioning and installation. The user takes out another set of graphite columns 4 so that the direction of the cooling hole 16 is the same as that of the discharge pipe 14. At the same time, the positioning blocks 19 at one end of the positioning plate 17 are inserted into the interior of the positioning groove 18, and the installation is carried out in this way.

[0041] Step 3: Fixing. When the top of the last group of graphite columns 4 is higher than the discharge pipe 14, put the elastic seal 5 on one end of the graphite column 4, and then insert the compression sleeve 6 into one end of the housing 1. Use the extended bolts 10 to fix the housing 1, sealing flange 8, compression sleeve 6 and spring 11;

[0042] Step 4: Working, the high-temperature material enters the interior of the shell 1 through the first feed pipe 12, flows upward through the material hole 15 inside the graphite column 4, and finally discharges the device through the compression sleeve head 6. At the same time, the low-temperature coolant enters the interior of the shell 1 through the second feed pipe 13, passes through the cooling hole 16 on the side of the graphite column 4, and the high-temperature material transfers heat with the graphite column 4. The graphite column 4 quickly heats up. At this time, the coolant can quickly transfer heat with the graphite column 4, and the heated coolant is discharged through the discharge pipe 14;

[0043] Step 5: Automatic pressure control. The pressure in chamber 1 or chamber 2 can be detected through the pressure tube 21 and the pressure gauge 22. When the pressure in chamber 1 or chamber 2 is too high, the pressure pushes the slide rod 27 through the piston 24 to squeeze the limit switch 23. The limit switch 23 controls the operation of the dual-axis motor 33. The output end of the dual-axis motor 33 can control the opening range of the ball valve 28 through the worm 32 and the worm gear 31, thereby self-regulating the pressure inside chamber 1 or chamber 2. When the pressure inside chamber 1 or chamber 2 returns to a low level, the controller and the dual-axis motor 33 control the worm 32 and the worm gear 31 to work in the reverse direction, so that the ball valve 28 is within the normal opening range.

[0044] Step 6: Alarm. If the pressure inside chamber 1 or chamber 2 is too high for a long time, the slide bar 27 controls the limit switch 23 to be open for a long time, and the user is alerted through the controller and the alarm.

[0045] Step 7: Manual pressure control: the user can control the opening range of the ball valve 28 by turning the handle 34, and can also protect the device.

[0046] Working principle: When the user installs this device, the user first fixes the shell 1, and then puts the elastic seal 5 on the bottom end of the graphite column 4 respectively, so that the inner walls of the elastic seal 5 are respectively fitted with the surface of the second positioning sleeve 7, so that the elastic seal 5 can be limited by the second positioning sleeve 7, and at the same time, it can be fixed under the elasticity of the elastic seal 5 itself to prevent the elastic seal 5 from falling off. The user installs a group of graphite columns 4 inside the shell 1, so that the bottom end of the graphite column 4 is located inside the first positioning sleeve 3, and at the same time, the elastic seal 5 at the bottom end of the graphite column 4 is fitted with the limiting sleeve 2. At this time, the graphite column 4 can be positioned by the first positioning sleeve 3, so that the central axis of the graphite column 4 coincides with the central axis of the shell 1, and at the same time At the same time, the user makes the hole direction of the cooling hole 16 the same as that of the discharge pipe 14, and then takes out another set of graphite columns 4 so that the hole direction of the cooling hole 16 is the same as that of the discharge pipe 14, and at the same time, the positioning blocks 19 at one end of the positioning plate 17 are respectively inserted into the inside of the positioning groove 18, thereby completing the positioning work, and so on to install until the top of the last set of graphite columns 4 is higher than the discharge pipe 14. At this time, the user puts the elastic seal 5 on one end of the graphite column 4, and then the user inserts the pressure sleeve head 6 into one end of the shell 1, and continuously moves it down until the elastic seal 5 at the top of the graphite column 4 fits with one end of the pressure sleeve head 6, and at the same time the second positioning sleeve 7 is put on the surface of the graphite column 4, and then the sealing ring 9 is put on the middle of the pressure sleeve head 6, and finally the user first lengthens the bolt 10 Fix the shell 1 and the sealing flange 8, then pass one end of the extension bolt 10 through the pressure sleeve 6, put on the spring 11, and finally tighten it to complete the installation. At this time, the spring 11 provides pressure to the pressure sleeve 6 under the action of its own elastic force to avoid damage to the graphite column 4 caused by overpressure. At the same time, the elastic seal 5 can provide sealing and avoid extrusion between the graphite columns 4, thereby protecting the graphite columns 4. The user uses bolts to connect the pressure sleeve 6, the first feed pipe 12, the second feed pipe 13 and the discharge pipe 14 in the device to the external pipeline, and then connect the device to the controller and alarm through the travel switch 23 and the dual-axis motor 33. When in use, the high-temperature material enters the interior of the shell 1 through the first feed pipe 12 and passes through the graphite column 4. The internal material hole 15 flows upward and is finally discharged from the device through the compression sleeve head 6. At the same time, the low-temperature coolant enters the interior of the shell 1 through the second feed pipe 13. The coolant can be dispersed through the conical diverter plate 29 at one end of the second feed pipe 13 and passes through the cooling hole 16 on the side of the graphite column 4. The high-temperature material transfers heat with the graphite column 4, and the graphite column 4 heats up rapidly. At this time, the coolant can quickly transfer heat with the graphite column 4, thereby realizing rapid cooling of the material. The heated coolant is discharged through the discharge pipe 14. At the same time, the pressure of the coolant in the second chamber can be detected by the upper group of pressure pipes 21 and the pressure gauge 22, and the pressure of the material in the first chamber can be detected by the lower group of pressure pipes 21 and the pressure gauge 22.When the pressure in chamber 1 or chamber 2 is too high, the pressure pushes the piston 24 to slide in the middle of the pressure tube 21, and the travel switch 23 can be squeezed through the slide rod 27. The travel switch 23 controls the operation of the dual-axis motor 33. The output end of the dual-axis motor 33 drives the worm 32 to rotate, and the worm 32 drives the worm gear 31 to rotate. The rotating worm gear 31 can control the opening range of the ball valve 28, thereby being able to self-regulate the pressure inside chamber 1 and chamber 2 to avoid excessive pressure in chamber 1 or chamber 2, which may cause graphite The damage of column 4 affects the normal use of the device, or causes damage to the elastic seal 5, avoiding the risk of leakage. If the pressure in chamber 1 is too high, it means that the material is discharged excessively. At this time, the opening range of ball valve 28 is reduced by dual-axis motor 33, worm 32 and worm gear 31 to reduce the entry of material, thereby reducing the pressure inside chamber 1. If the pressure in chamber 2 is too high, it means that the coolant is discharged excessively. At this time, the opening range of ball valve 28 is reduced by dual-axis motor 33, worm 32 and worm gear 31 to reduce the coolant. The entry of the first or second chambers reduces the pressure inside the second chamber. When the pressure inside the first or second chambers is reduced, the controller controls the output end of the dual-axis motor 33 to work in the reverse direction, so that the ball valve 28 in the middle of the first feed pipe 12 and the second feed pipe 13 is in the normal opening range. If the pressure inside the first or second chamber is too high for a long time, the slide bar 27 controls the limit switch 23 to be open for a long time. At this time, the controller and the alarm remind the user that the graphite column 4 or the elastic seal 5 inside the housing 1 is at risk of damage, so that the user can make a correct judgment, thereby protecting the device and extending its service life. If the device cannot automatically adjust the pressure normally, the user can also control the opening range of the ball valve 28 by turning the handle 34, which can also protect the device. The device is not only convenient for users to install and reduces their work difficulty, but also can protect the graphite column 4 and the elastic seal 5, thereby extending their service life. It can also automatically reduce pressure, expand its scope of use, reduce its limitations, and reduce user losses.

A method for operating a graphite chemical cooler for heat exchange according to any one of claims 1 to 8, characterized in that: Step 1: Installation, the user first fixes the shell (1), and then sleeves the elastic seal (5) on the bottom end of the graphite column (4), and the user installs the graphite column (4) inside the shell (1) so that the elastic seal (5) at the bottom end of the graphite column (4) fits with the limiting sleeve (2), and the graphite column (4) can be positioned by the first positioning sleeve (3), and the hole direction of the cooling hole (16) is controlled to be the same as the hole direction of the discharge pipe (14); Step 2: Positioning and installation. The user takes out another set of graphite columns (4) so that the direction of the cooling hole (16) is the same as that of the discharge pipe (14). At the same time, the positioning blocks (19) at one end of the positioning plate (17) are respectively inserted into the interior of the positioning groove (18). The installation is carried out in this way. Step 3: Fixing. When the top of the last group of graphite columns (4) is higher than the discharge pipe (14), the elastic seal (5) is placed on one end of the graphite column (4), and the compression sleeve (6) is inserted into one end of the housing (1). The housing (1), the sealing flange (8), the compression sleeve (6) and the spring (11) are fixed by lengthening the bolts (10); Step 4: Working, the high-temperature material enters the interior of the shell (1) through the first feed pipe (12), flows upward through the material hole (15) inside the graphite column (4), and finally discharges the device through the compression sleeve (6). At the same time, the low-temperature coolant enters the interior of the shell (1) through the second feed pipe (13), passes through the cooling hole (16) on the side of the graphite column (4), and heat transfer occurs between the high-temperature material and the graphite column (4). The graphite column (4) quickly heats up. At this time, the coolant can quickly transfer heat to the graphite column (4), and the heated coolant is discharged through the discharge pipe (14); Step 5: Automatic pressure control. The pressure in chamber 1 or chamber 2 can be detected through the pressure tube (21) and the pressure gauge (22). When the pressure in chamber 1 or chamber 2 is too high, the pressure pushes the slide bar (27) through the piston (24) to squeeze the travel switch (23). The travel switch (23) controls the operation of the dual-axis motor (33). The output end of the dual-axis motor (33) can control the opening range of the ball valve (28) through the worm (32) and the worm gear (31), thereby self-regulating the pressure inside chamber 1 or chamber 2. When the pressure inside chamber 1 or chamber 2 is restored and lowered, the worm (32) and the worm gear (31) are controlled to work in reverse under the action of the controller and the dual-axis motor (33), so that the ball valve (28) is in a normal opening range. Step 6: Alarm. If the pressure inside chamber 1 or chamber 2 is too high for a long time, the slide bar (27) controls the travel switch (23) to open for a long time, and the user is alerted through the controller and the alarm. Step 7: Manual pressure control: the user can control the opening range of the ball valve (28) by turning the handle (34), and can also protect the device.
