[0017] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0018] The positive and progressive effects of this utility model are as follows:

[0019] The aforementioned enamel-lined reactor with an anti-clogging structure features a lifting mechanism at the top of the reactor body. A round rod is connected to the bottom of the lifting mechanism, and a tamping disc is installed at the bottom of the round rod above the discharge port. When the discharge port is blocked by large pieces of material, the lifting mechanism can drive the round rod and the tamping disc downwards. The tamping disc pushes the blockage in the discharge port until it moves below the gate valve, thus automatically discharging the blockage without manual cleaning. This effectively reduces labor intensity and quickly clears the discharge port, ensuring discharge efficiency.

[0020] The tamping disc is detachably connected to the bottom of the round rod via a locking mechanism. The locking mechanism consists of multiple telescopic rods, which are linked to the injection mechanism. During disassembly, the injection mechanism draws in the medium from the telescopic rods, causing them to retract and release the lock on the tamping disc. Disassembly can then be completed by manually pulling. During installation, the connecting sleeve of the tamping disc is inserted into the bottom of the round rod, and the injection mechanism injects the medium, causing the telescopic rods to extend and complete the locking installation. The entire disassembly and assembly process is convenient and efficient, facilitating replacement when the tamping disc is worn or damaged.

[0021] Furthermore, the injection mechanism is fixedly installed on the movable plate of the lifting mechanism, and its pressure rod corresponds to the shell seat at the top of the reactor. When the tamping plate needs to be disassembled, the lifting mechanism drives the round rod to move downward, causing the pressure rod to contact the shell seat and be blocked. The lifting mechanism continues to move downward, which drives the piston of the injection mechanism to move, thereby realizing the suction of the medium. During installation, the lifting mechanism drives the round rod to move upward, the pressure rod separates from the shell seat, and the injection mechanism realizes the injection of the medium under the action of the spring force. The entire injection process is powered by the movement of the lifting mechanism, eliminating the need for manual operation of the injection medium, further improving the convenience of disassembling and assembling the tamping plate.

[0032] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0033] like Figures 1-8 As shown, the enamel-lined reactor with an anti-clogging structure includes a reactor body 1; the bottom of the reactor body 1 is provided with a discharge port 101.

[0034] A lifting mechanism 6 is installed on the top of the reactor body 1. A round rod 5 is fixed at the bottom of the lifting mechanism 6. The round rod 5 extends into the reactor body 1, and the bottom end of the round rod 5 is connected to a tamping plate 8 through a locking mechanism 10. The tamping plate 8 is located above the discharge port 101.

[0035] The locking mechanism 10 is composed of multiple telescopic rods; the multiple telescopic rods are installed in a ring array at the bottom end of the round rod 5, and a connecting sleeve 801 is fixed at the top center of the tamping disc 8, and the connecting sleeve 801 is inserted into the bottom end of the round rod 5. The inner wall of the connecting sleeve 801 is provided with a positioning hole 803 for the insertion of the end of the telescopic rod; the telescopic rod is connected to the injection mechanism 9.

[0036] like Figures 2-3 As shown, a gate valve 4 is installed at the bottom of the discharge port 101. The gate valve 4 is used to control the opening and closing of the discharge port 101.

[0037] The aforementioned enamel-lined reactor discharges the reacted materials through discharge port 101; the normal material discharge process is as follows: Figure 2 As shown, the tamping disc 8 is located above the discharge port 101; when large pieces of material enter the discharge port 101 and cause blockage, the lifting mechanism 6 drives the round rod 5 and the tamping disc 8 to move downwards. The tamping disc 8 pushes the blockage in the discharge port 101 until it moves below the gate valve 4. Figure 5 As shown, to remove blockages and prevent them from affecting subsequent material discharge, after clearing the discharge port 101, the lifting mechanism 6 drives the round rod 5 and the tamping disc 8 to move upwards to reset, returning to the position shown. Figure 2 The state shown is as described. This design automatically clears the discharge port 101, preventing continuous blockage and affecting discharge efficiency.

[0038] Furthermore, the tamping disc 8 adopts a design that facilitates disassembly and assembly, making it easy to disassemble and replace.

[0039] During disassembly, the injection mechanism 9 draws in the medium (such as gas or hydraulic oil) inside the telescopic rod, causing the telescopic rod of the locking mechanism 10 to retract under the action of air or hydraulic pressure. The end of the telescopic rod leaves the positioning hole 803, thus canceling the locking installation on the tamping disc 8. The tamping disc 8 can be manually pulled down to complete the disassembly.

[0040] During installation, the connecting sleeve 801 of the tamping disc 8 is inserted into the bottom end of the round rod 5. Then, the injection mechanism 9 injects the medium into the telescopic rod. Under the action of air pressure or hydraulic pressure, the telescopic rod extends and the end of the telescopic rod is inserted into the positioning hole 803 to complete the locking installation.

[0041] like Figure 2 As shown, a motor 3 is fixedly installed on the top of the reactor body 1. A housing 301 is provided on one side of the motor 3. The motor 3 is connected to an output shaft 302, and the output shaft 302 extends into the reactor body 1. Multiple stirring blades 7 are fixed at the bottom end of the output shaft 302.

[0042] The above structure allows for the stirring of materials within the reactor body 1. Specifically, the motor 3 drives the output shaft 302 to rotate, and the stirring blades 7 on the output shaft 302 rotate together, thereby achieving material stirring.

[0043] The housing 301 on one side of the motor 3 has a transmission component, such as a gear set, and the motor 3 is connected to the output shaft 302 through the transmission component.

[0044] The output shaft 302 has a circular hole along its length at its center, and the circular rod 5 is clearance-fitted with the circular hole.

[0045] The circular hole on the output shaft 302 provides space for the circular rod 5 to be installed, and does not hinder the rotation of the stirring blade 7 and the output shaft 302.

[0046] like Figure 1 As shown, the lifting mechanism 6 includes a fixed frame 601 fixedly installed on the top of the reactor body 1. A telescopic member 602 is fixed to the top of the fixed frame 601. A movable plate 603 is fixed to the output end of the telescopic member 602. The bottom of the movable plate 603 is fixed to the top of the round rod 5, and the movable plate 603 is connected to a guide part.

[0047] The guide part includes a guide post 605 fixedly installed on the movable plate 603, and a guide sleeve 604 fixedly installed on the fixed frame 601. The guide post 605 and the guide sleeve 604 are slidably engaged.

[0048] The telescopic component 602 can be a pneumatic cylinder or a hydraulic cylinder. The telescopic component 602 extends and retracts, causing the movable plate 603, the round rod 5, and the tamping disc 8 to move up and down, moving the tamping disc 8 above the discharge port 101 or below the gate valve 4. During this up-and-down movement, the movable plate 603 moves the guide post 605 along with it, causing the guide post 605 to slide against the guide sleeve 604. The guide post 605 and the guide sleeve 604 provide guidance for the up-and-down movement.

[0049] like Figure 7 As shown, the injection mechanism 9 includes a first cylinder 901 fixedly installed on the top surface of the movable plate 603; a first piston 904 is fitted inside the first cylinder 901, and a movable column 902 is fixed on the top of the first piston 904. The movable column 902 is slidably sleeved with the top of the first cylinder 901, and the movable column 902 extends outside the top of the first cylinder 901. A spring 905 is provided inside the first cylinder 901. A retaining ring 906 is fixed on the inner wall of the bottom end of the first cylinder 901, and the retaining ring 906 is located at the bottom of the first piston 904. A first interface 907 is fixedly connected to the bottom of the first cylinder 901, and the first interface 907 is connected to the channel 908 provided in the round rod 5 and the movable plate 603; a pressure rod 903 is fixed on the top of the movable column 902, and the bottom end of the pressure rod 903 faces the housing 301.

[0050] like Figure 7 As shown, one end of the spring 905 abuts against the top inner wall of the first cylinder 901, and the other end of the spring 905 abuts against the top surface of the first piston 904.

[0051] like Figure 7 As shown, the pressure rod 903 has an inverted L-shaped structure; the movable plate 603 has a guide hole 6031, and the pressure rod 903 slides in conjunction with the guide hole 6031.

[0052] like Figure 8As shown, the telescopic rod includes a second cylindrical body 1001 fixedly installed inside the bottom side wall of the round rod 5. A second piston 1003 is fitted onto the second cylindrical body 1001. A positioning post 1004 is fixed on one side of the second piston 1003. The positioning post 1004 is slidably fitted with one end of the second cylindrical body 1001 and is inserted into the positioning hole 803. A second interface 1002 is provided at the other end of the second cylindrical body 1001 and is connected to the channel 908.

[0053] After the reaction vessel has been used and all materials have been drained, check the tamping disc 8 and manually determine if it needs to be replaced. The specific disassembly procedure for the tamping disc 8 is as follows:

[0054] Start the lifting mechanism 6. The lifting mechanism 6 drives the round rod 5 and the tamping disc 8 to move downwards until the tamping disc 8 moves below the gate valve 4. At this time, the bottom end of the pressure rod 903 of the injection mechanism 9 is just in contact with the top surface of the housing 301. Figures 5-6 As shown.

[0055] After observing and determining that the tamping disc 8 needs to be replaced, the lifting mechanism 6 continues to drive the round rod 5 to move downward. Since the bottom end of the pressure rod 903 is blocked by the housing 301 and cannot move downward, the pressure rod 903 will drive the movable column 902 of the injection mechanism 9 to move upward, thereby driving the first piston 904 in the first cylinder 901 to move upward.

[0056] When the first piston 904 moves upward, it will have a suction effect on the medium in the first cylinder 901. The medium in the second cylinder 1001 enters the first cylinder 901 through the channel 908, causing the telescopic rod to contract and increasing the compression of the spring 905.

[0057] When the telescopic rod retracts, the second piston 1003 drives the positioning pin 1004 to move into the second cylinder 1001. The end of the positioning pin 1004 gradually disengages from the positioning hole 803, releasing the lock on the tamping disc 8.

[0058] After the lock is released, manually pull down the tamping disc 8 to separate the connecting sleeve 801 at the top of the tamping disc 8 from the bottom of the round rod 5, thus completing the disassembly of the tamping disc 8.

[0059] After removing the old tamping disc 8, install the new tamping disc 8. The specific steps are as follows:

[0060] Align the connecting sleeve 801 on the top of the tamping disc 8 to be installed with the bottom end of the round rod 5, and insert the connecting sleeve 801 into the bottom end of the round rod 5.

[0061] The lifting mechanism 6 drives the round rod 5 and the tamping disc 8 to move upward, causing the pressure rod 903 to separate from the housing 301. The first piston 904 returns to its original position downward under the elastic force of the spring 905 until the first piston 904 contacts the retaining ring 906. It should be noted that when the first piston 904 contacts the retaining ring 906, the spring 905 is still in a compressed state.

[0062] When the first piston 904 returns to its original position, the medium is injected into the second cylinder 1001 through the first interface 907 and the channel 908. Under the action of air pressure or hydraulic pressure, the second piston 1003 drives the positioning pin 1004 to extend and insert into the corresponding positioning hole 803 on the inner wall of the connecting sleeve 801, thus completing the locking and installation of the tamping disc 8.

[0063] Finally, the lifting mechanism 6 drives the round rod 5 and the tamping disc 8 to move upward and reset until the tamping disc 8 returns to its initial position above the discharge port 101, completing the entire installation process.

[0064] Through the above design, the injection mechanism 9 is powered by the lifting mechanism 6, and the injection mechanism 9 can draw or discharge the medium without manual operation, which facilitates the disassembly and assembly of the tamping disc 8.

[0065] The connecting sleeve 801 has a boss 802 fixed inside, and the bottom end of the round rod 5 is provided with a groove, and the boss 802 is inserted into the groove.

[0066] The boss 802 and the groove are used for positioning. After the two are aligned and inserted, the positioning hole 803 is aligned with the positioning post 1004.

[0067] In practical implementation, a sealing ring is provided at the inner ring of the top of the connecting sleeve 801. After the round rod 5 is inserted into the connecting sleeve 801, the sealing ring provides a seal.

[0068] like Figure 1 As shown, the bottom of the reactor body 1 is fixed with multiple support legs 2. The support legs 2 provide support for the reactor body 1.

The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
