Abstract
Description
Technical Field
[0001] This invention relates to the field of high-pressure homogenizer technology, and in particular to a homogenizer pump body with micropores, which is different from ordinary homogenizer valve structure homogenizers. Background Technology
[0002] High-pressure homogenizers, also known as "ultra-high pressure nano-homogenizers," use mechanical plungers or hydraulic pressure to force suspended materials to flow at high speed through a specially structured cavity (the mainstream design is a high-pressure homogenizing cavity, a collision cavity, or a microporous cavity) under ultra-high pressure (up to 60,000 psi). This causes the material to lose pressure instantaneously, and the liquid flow changes direction, causing a shearing effect that leads to a series of changes in the material's physical, chemical, and structural properties, ultimately achieving the effect of reduced particle size and increased uniformity.
[0003] Most existing high-pressure homogenizers consist of a single pressure module, with a single-shaft motor driving a crankshaft housing and a synchronous pulley, which in turn drives a ceramic plunger in reciprocating motion. The biggest problem with single-module homogenizers is that during the plunger's reciprocating motion, the squeezing efficiency of the fluid within the high-pressure through-hole plate decreases as the plunger starts and approaches its end point. This results in sinusoidal pulses at high pressures, which are particularly large under ultra-high pressures. These pulses cause variations in the closing speed of the inlet and outlet valves, leading to highly unstable internal pressure and large flow fluctuations during operation of the high-pressure homogenizer.
[0004] The prior art, application number 2021110818670, discloses a constant pressure nano-homogenizer. Although it solves the problems of high pressure homogenizers being unstable during operation and having limited flow, as well as the poor wear resistance of existing valve seats and valve cores, resulting in poor homogenization effects and increased product costs, it still has the following drawbacks:
[0005] When the material reaches the homogenizing valve directly from the discharge channel in the discharge plate, the distance between the valve body and the valve core in the homogenizing valve is adjusted by a cylinder. When the material reaches the homogenizing valve from the discharge channel, there may be unstable pressure in the discharge channel. In this process, there is no pressure boosting or stabilizing structure, and pressure can only be boosted by adjusting the distance between the valve seat and the valve core to achieve primary homogenization of the material. Furthermore, since the pressure at the homogenizing valve location is very high, the cylinder has high requirements for pushing the valve core. If the pressure between the valve core and the valve seat is too high, it may cause the cylinder to move back and forth, resulting in unstable and dynamic changes in the distance between the valve seat and the valve core. Therefore, in order to prevent the above situation from occurring, the cylinder size must be increased to enhance the cylinder thrust. However, this will not only increase the cost but also increase the installation space of the cylinder. Summary of the Invention
[0006] The purpose of this invention is to solve the above problems by designing a microporous homogenizing pump body with a uniquely designed microporous drainage channel.
[0007] To achieve the above objectives, the technical solution of the present invention is a microporous homogenizing pump body, comprising a feeding module, a perforated plate, a discharge module, and a conveying device. The discharge port of the feeding module is connected to the feeding port of the perforated plate, and the discharge port of the perforated plate is connected to the feeding port of the discharge module. The conveying device is disposed on the back of the perforated plate for conveying the material in the feeding module to the discharge module. The pump also includes a microporous injection module, a pressure stabilizing module, and a pressure boosting module.
[0008] The micro-orifice injection module has a funnel-shaped flow channel for pressurizing the material and a collection chamber for concentrating the mist material and forming a liquid material inside; the pressure stabilizing module has a pressure stabilizing channel inside.
[0009] The wide end of the funnel-shaped drainage channel is connected to the discharge port of the discharge module, the narrow end of the funnel-shaped drainage channel is connected to the liquid collection chamber, and the discharge port of the liquid collection chamber is connected to the pressure stabilizing channel in the pressure stabilizing module, wherein the inner diameter of the outlet end of the liquid collection chamber is half the inner diameter of the pressure stabilizing channel.
[0010] The chamber of the booster module is provided with a homogenizing valve assembly, which includes a valve seat, a valve body and a valve core. The valve seat is located inside the valve body and there is a certain distance between it and the valve core.
[0011] The right end of the booster module is provided with a handle assembly. The front end of the handle assembly extends into the interior of the booster module and is connected to the valve core. When the material passes through the gap between the valve seat and the valve core, the distance between the valve seat and the valve core is adjusted by rotating the handle assembly to adjust the homogenization pressure.
[0012] Preferably, the feeding module includes a feeding plate with a feeding channel and three one-way feeding valves disposed on the upper end of the feeding plate. An annular high-pressure seal is provided between the feeding plate and the three one-way feeding valves. The inlets of the three one-way feeding valves are all vertically connected to the feeding channel in the feeding plate. The feeding channel has at least one inlet.
[0013] The three one-way feed valves are respectively connected to three independent perforated plates, which are connected to the discharge module directly above.
[0014] Preferably, the discharge module includes a high-pressure through-hole plate with a discharge channel and three one-way discharge valves disposed at the lower end of the high-pressure through-hole plate. An annular high-pressure seal is provided between the high-pressure through-hole plate and the three one-way discharge valves. The discharge ports of the three one-way discharge valves are all vertically connected to the discharge channel in the high-pressure through-hole plate, and the inlets of the three one-way discharge valves are respectively connected to three independent multi-hole plates.
[0015] Preferably, the perforated plate is provided with a herringbone channel, which includes a main channel and two sub-channels that are respectively connected to the upper and lower ends of the main channel. The main channel is located on the side of the perforated plate. The inlet of one sub-channel is connected to the outlet of the corresponding one-way feed valve, and the outlet of the other sub-channel is connected to the inlet of the corresponding one-way discharge valve.
[0016] Preferably, the conveying device is disposed on the back of the three perforated plates. The conveying device includes a fixing block and three independent guide blocks disposed on the back of the fixing block. The three guide blocks correspond one-to-one with the three perforated plates. Each guide block is provided with a plunger rod. One end of the plunger rod passes through the guide block and the fixing block in sequence and is inserted and connected to the main channel on the back of the corresponding perforated plate. The plunger rod performs piston reciprocating motion relative to the main channel.
[0017] Preferably, the handle assembly includes a push rod, a handle sleeve, a handle, and a support mechanism. The support mechanism includes a support sleeve, a copper pad, a stacked spring, a T-shaped stacked spring rod, a plane bearing, and a support ring. The support sleeve is fixedly connected to the pressurization module. One end of the push rod is fixedly connected to the side of the valve core away from the valve body, and the other end extends into the support sleeve and abuts against the copper pad.
[0018] The copper pad, plane bearing, support ring, stacked spring, and T-shaped stacked spring rod are arranged sequentially from left to right on the inner side of the support sleeve. The stacked spring is sleeved on the T-shaped stacked spring rod. The T-shaped end of the T-shaped stacked spring rod is connected to the handle sleeve, and the other end is inserted and connected to the support ring. The handle is set on the outer edge surface of the handle sleeve, and the handle sleeve is threadedly connected to the outer edge surface of the support sleeve.
[0019] Preferably, at least three guide rings are provided on the outer side of the push rod along the axial direction, and all three guide rings are provided on the inner side of the support sleeve, and the push rod is slidably connected to the three guide rings.
[0020] Preferably, there is a certain gap between the copper pad and the stacked spring and the inner wall of the support sleeve.
[0021] Preferably, the left end of the high-pressure through-hole plate is provided with an explosion-proof component, which includes a fixing sleeve, a screw, a torsion cylinder, a T-shaped pressure relief pipe, a compression spring, a T-shaped pressure relief rod, and a pressure relief valve seat. One end of the screw is fixedly connected to the torsion cylinder, and the other end is threadedly connected to the fixing sleeve. The pressure relief valve seat is located on the inner side of the high-pressure through-hole plate and communicates with the discharge channel inside the high-pressure through-hole plate. The compression spring is located on the inner side of the fixing sleeve, and its two ends abut against the screw and the T-shaped pressure relief rod, respectively.
[0022] One end of the T-shaped pressure relief rod is connected to the fixed sleeve, and the other end extends through the T-shaped pressure relief pipe to the location of the pressure relief valve seat. A ball is provided between the front end of the T-shaped pressure relief rod and the inlet of the pressure relief valve seat. Under the action of the compression spring, the T-shaped pressure relief rod pushes the ball against the outlet of the pressure relief valve seat.
[0023] Preferably, the upper end face of the high-pressure through-hole plate is provided with a high-pressure detection mechanism for detecting the internal pressure of the discharge channel. The high-pressure detection mechanism is a high-pressure test gauge or a high-pressure device, which detects the pressure of the discharge channel inside the high-pressure through-hole plate in real time.
[0024] Its advantages over existing technologies are:
[0025] 1. In this invention, a micro-orifice injection module and a pressure stabilizing module are set between the discharge module and the pressurization module. After the material enters the funnel-shaped flow channel in the micro-orifice injection module, it will undergo pressurization and first homogenization. The flow port of the funnel-shaped flow channel narrows from a 28mm diameter to a 2mm diameter to generate pressure. The flow port is made of a highly wear-resistant material. The material changes from a mist to a liquid as it enters the liquid collection chamber from the funnel-shaped flow channel. Then, after entering the pressure stabilizing channel in the pressure stabilizing module, it will turbulently rotate and generate a shearing effect. The material will be further homogenized under the action of shearing force. The pressure stabilizing channel plays the role of stabilizing pressure and flow.
[0026] 2. In this invention, the pressure of the material passing through the gap between the valve seat and the valve core is adjusted by adjusting the distance between the valve seat and the valve core through the handle assembly, thereby achieving the adjustment of the material homogeneity. Moreover, due to the presence of the pressure stabilizing module and the micro-orifice injection module, when the pressure of the material passing through the valve seat and the valve core changes, it will not affect the pressure inside the discharge channel of the discharge module, nor will it affect the closing speed of the inlet and outlet check valves, ensuring the stability of the internal pressure of the high-pressure homogenizer during operation, with small flow fluctuations. Furthermore, the handle assembly adjusts the distance between the valve core and the valve seat entirely mechanically, which not only has high adjustment accuracy but also good stability.

Detailed Implementation
[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0037] like Figure 1 and Figure 2 The micro-orifice homogenizing pump shown mainly includes a feeding module 1, a perforated plate 3, a discharge module 2, a conveying device 7, a micro-orifice injection module 4, a pressure stabilizing module 5, and a pressure boosting module 6. The discharge port of the feeding module 1 is connected to the inlet of the perforated plate 3, and the discharge port of the perforated plate 3 is connected to the inlet of the discharge module 2. The micro-orifice injection module 4, the pressure stabilizing module 5, and the pressure boosting module 6 are arranged sequentially from left to right at the right end of the discharge module 2 and are connected to the discharge module 2. The material enters from the feeding module 1 and is conveyed to the perforated plate 3. Then, the material is conveyed to the discharge module 2 by the conveying device 7 located on the back of the perforated plate 3. Then, the material undergoes the first pressure boosting and homogenization by the micro-orifice injection module 4, the pressure is stabilized by the pressure stabilizing module 5, and then the material undergoes the second homogenization by the pressure boosting module 6.
[0038] like Figure 4 As shown, the feeding module 1 includes a feeding plate 11 and three one-way feeding valves 12 disposed on the upper surface of the feeding plate 11. A feeding channel 111 is disposed along its length inside the feeding plate 11, and the feeding channel 111 is provided with at least one inlet, or two inlets. The two inlets are respectively disposed at both ends of the feeding channel 111, that is, the feeding channel 111 can feed material from one end or both ends. The three one-way feeding valves 12 are all vertically connected to the feeding channel 111 inside the feeding plate 11. An annular high-pressure seal is provided between the feeding plate 11 and the three one-way feeding valves 12 to ensure that the material does not leak.
[0039] refer to Figure 4 The aforementioned perforated plate 3 is provided in three parts, and each part is connected to one-way feed valve 12. The upper part of the three perforated plates 3 is connected to the discharge module 2, ensuring that the material flows in one direction only, from feed module 1 → perforated plate 3 → discharge module 2.
[0040] like Figure 4 As shown, the discharge module 2 includes a high-pressure through-hole plate 21 and three one-way discharge valves 22 disposed on the lower end face of the high-pressure through-hole plate 21. A discharge channel 211 is disposed inside the high-pressure through-hole plate 21 along its length. The discharge channel 211 also has two discharge ports. The discharge port at the left end is connected to the explosion-proof component 8 connected to it (this discharge port is closed during operation and will only be opened when pressure needs to be released). The discharge port at the right end is connected to the micro-orifice injection module 4. The discharge ports of the three one-way discharge valves 22 are all vertically connected to the discharge channel 211 inside the high-pressure through-hole plate 21, while the inlets of the three one-way discharge valves 22 are respectively connected to the three independent medium-sized perforated plates 3 below.
[0041] The one-way feed valve 12 and one-way discharge valve 22 mentioned above are both one-way open. They will automatically open if the external pressure is too high to ensure that the material will not flow back during conveying.
[0042] like Figure 6 As shown, each perforated plate 3 has a herringbone channel 31 inside. The herringbone channel 31 is composed of a main channel 312 and two sub-channels 311. The main channel 312 is located on the side of the perforated plate 3 and is perpendicular to the side. The two sub-channels 311 are located at the upper and lower ends of the main channel 312 and are connected to the main channel 312. The inlet of one sub-channel 311 is connected to the outlet of the corresponding one-way feed valve 12 (i.e., the sub-channel 311 located at the lower end of the main channel 312), and the outlet of the other sub-channel 311 is connected to the inlet of the corresponding one-way discharge valve 22 (i.e., the sub-channel 311 located at the upper end of the main channel 312). By applying pressure to the main channel 312, the material in the sub-channel 311 is transported to the discharge module 2 by the principle of pumping. The power for pumping is provided by the conveying device 7.
[0043] refer to Figure 2 , Figure 3 The conveying device 7 includes a fixed block 71, three independent guide blocks 72 disposed on the back of the fixed block 71, and a plunger rod 73 that is slidably connected to the guide blocks 72 and the fixed block 71. There are three plunger rods 73, which correspond one-to-one with the three guide blocks 72. The back of the three perforated plates 3 are fixed to the front of the fixed block 71 and correspond one-to-one with the three guide blocks 72. One end of the plunger rod 73 passes through the guide block 72 and the fixed block 71 in sequence and is slidably inserted into the main channel 312 on the back of the corresponding perforated plate 3. The plunger rod 73 can reciprocate in relation to the main channel 312. The fixed block 71 can make the three plunger rods 73 more secure and stable during operation.
[0044] When the plunger rod 73 moves along the outer side of the main channel 312, the overall volume of the main channel 312 increases and the pressure decreases. Under the action of external pressure, the material opens the one-way feed valve 12 and enters the herringbone channel 31 in the perforated plate 3. When the plunger rod 73 moves along the inner side of the main channel 312, the overall volume of the main channel 312 decreases and the pressure in the herringbone channel 31 increases, opening the one-way discharge valve 22. The material enters the discharge channel 211 in the high-pressure through-hole plate 21. At the same time, the material in the discharge channel 211 increases and the pressure increases, and the material will enter the micro-hole injection module 4.
[0045] During operation, the three plunger rods 73 are driven by the same crankshaft. The crankshaft, driven by the motor, drives the three plunger rods 73 to reciprocate in sequence, thereby opening the three one-way feed valves 12 in sequence. Similarly, the three one-way discharge valves 22 will also open in sequence. This is existing technology and will not be described in detail here.
[0046] like Figure 7As shown, a funnel-shaped drainage channel 41 for pressurizing the material and a liquid collection chamber 42 for concentrating the mist material into a liquid material are formed in the microporous drainage module. The wide end of the funnel-shaped drainage channel 41 is connected to the discharge port of the discharge module 2, and the narrow end is connected to the liquid collection chamber 42. The diameter of the funnel-shaped drainage channel 41 will shrink from 28mm to 2mm to generate pressure. The drainage port is made of a highly wear-resistant material to ensure its strength.
[0047] The diameter of the coarse end of the funnel-shaped flow channel 41 is the same as the diameter of the feed channel 111, ensuring that the material can smoothly enter the funnel-shaped flow channel 41. When the material enters the funnel-shaped flow channel 41, it will generate great pressure at the narrow end of the funnel-shaped flow channel 41. The material will undergo the first homogenization under high pressure. At the same time, because the diameter of the narrow end of the funnel-shaped flow channel 41 is very small, the material will be sprayed out in the form of mist, which is not conducive to the subsequent second homogenization. Therefore, the liquid collection chamber 42 is set to convert the misty material back into liquid. The end of the liquid collection chamber 42 biased towards the funnel-shaped flow channel 41 is spherical, so that the material can easily concentrate towards the center after entering the liquid collection chamber 42, which is conducive to the formation of liquid material.
[0048] like Figure 7 As shown, a pressure stabilizing channel 51 is formed inside the pressure stabilizing module 5. The pressure stabilizing channel 51 is connected to the liquid collection chamber 42, and the inner diameter of the pressure stabilizing channel 51 is twice the inner diameter of the discharge port of the liquid collection chamber 42. In this way, the liquid collection chamber 42 and the pressure stabilizing channel 51 are distributed in a stepped manner. After the material comes out of the liquid collection chamber 42, it will undergo turbulent rotation. When passing through the stepped structure, it will be subjected to shearing force, and the material will be further sheared and crushed. The pressure stabilizing channel 51 plays the role of stabilizing pressure and flow. Then the material will enter the pressurizing module 6 for further homogenization.
[0049] refer to Figure 7 and Figure 8 A homogenizing valve assembly 61 is provided inside the cavity of the boosting module 6. The homogenizing valve assembly 61 includes a valve body 611, a valve seat 612, and a valve core 613. The valve body 611 is located inside the boosting module 6, while the valve seat 612 is located inside the valve body 611 and has a certain gap with the valve core 613. The valve seat 612 and the valve core 613 are arranged facing each other. The valve seat 612 is connected to the pressure stabilizing channel 51. A handle assembly 9 is provided at the right end of the boosting module 6. The front end of the handle assembly 9 extends into the interior of the boosting module 6 and is connected to the valve core 613. It is used to adjust the gap between the valve core 613 and the valve seat 612, thereby regulating the pressure when the material passes through the valve seat 612.
[0050] When the pressure changes as the material passes between valve seat 612 and valve core 613, the pressure in the discharge channel 211 will not be affected due to the micro-orifice injection device and pressure stabilizing module 5, thus improving the stability of the high-pressure homogenizer during operation.
[0051] like Figure 7 As shown, the handle assembly 9 mainly includes a top rod 94, a handle sleeve 91, a handle 92, and a support mechanism 93. The support mechanism 93 is mainly composed of a support sleeve 933, a copper pad 936, a stacked spring 932, a T-shaped stacked spring rod 931, a plane bearing 935, and a support ring 934. One end of the support sleeve 933 is fixedly connected to the pressurization module 6 and communicates with the internal cavity. The copper pad 936, plane bearing 935, support ring 934, stacked spring 932, and T-shaped stacked spring rod 931 are arranged sequentially from left to right on the inner side of the support sleeve 933 and are tightly attached to each other. The stacked spring 932 is sleeved on the T-shaped spring rod 934. On the spring rod 931, the T-shaped end of the T-shaped spring rod 931 is connected to the handle sleeve 91, and the other end is inserted and connected to the support ring 934. One end of the aforementioned push rod 94 is fixedly connected to the side of the valve core 613 away from the valve body 611, and the other end extends into the support sleeve 933 and abuts against the copper pad 936. The handle 92 is set on the outer edge surface of the handle sleeve 91. The handle sleeve 91 is threadedly connected to the outer edge surface of the support sleeve 933. When the force is transmitted, it will be transmitted from the T-shaped spring rod 931 to the support ring 934, the plane bearing 935, the copper pad 936 and the push rod 94 in sequence, pushing the push rod 94 to move back and forth.
[0052] When it is necessary to adjust the gap between the valve core 613 and the valve seat 612, the handle 92 is turned, causing the handle sleeve 91 to rotate. Since the handle sleeve 91 and the outer edge of the support sleeve 933 are threadedly connected, the handle sleeve 91 will move back and forth when it rotates, thereby driving the T-shaped spring rod 931 to rotate and push the T-shaped spring rod 931 to move back and forth. At the same time, one end of the T-shaped spring rod 931 will be inserted into the support ring 934, and the spring 932 will be compressed. When the stacked spring 932 rotates, it drives the support ring 934 to rotate and pushes it to move back and forth. The plane bearing 935 moves back and forth under the action of force, pushing the copper pad 936 to move back and forth. The copper pad 936 mainly plays a buffering role. Since copper is relatively soft, the copper pad 936 will deform under force to prevent the push rod 94 from being crushed. When the copper pad 936 moves back and forth, it pushes the push rod 94 to move back and forth, thereby realizing the adjustment of the distance between the valve seat 612 and the valve core 613.
[0053] To ensure that the stacked spring 932 can rotate smoothly together with the T-shaped stacked spring rod 931, there is a certain gap between the stacked spring 932 and the inner wall of the support sleeve 933, and the inner diameter of the stacked spring 932 is smaller than the inner diameter of the support ring 934. This ensures that the T-shaped stacked spring rod 931 will not contact the inner side of the support ring 934, facilitating the rotation of the T-shaped stacked spring rod 931. In addition, there is also a certain gap between the copper pad 936 and the inner wall of the support sleeve 933, allowing for some space for the deformation of the copper pad 936.
[0054] When the push rod 94 moves back and forth, it needs to always be on the same central axis as the pressurization module 6 to prevent the push rod 94 from shifting vertically during the back and forth movement. This would cause the valve core 613 and the valve seat 612 to not be directly facing each other, and the gap between the valve core 613 and the valve seat 612 would be inconsistent, with some parts being larger and some parts being smaller. As a result, the material passing through the gap between the valve seat 612 and the valve core 613 would have poor uniformity and be uneven. Therefore, at least three guide rings 941 are provided on the outer side of the push rod 94 along its axial direction. The three guide rings 941 are located between the push rod 94 and the support sleeve 933. The push rod 94 is slidably connected to the three guide rings 941. The guide rings 941 play a guiding role and ensure that the central axis of the push rod 94 is always on the same central axis as the pressurization module 6 when the push rod 94 moves back and forth, ensuring that the push rod 94 and the valve core 613 do not shift vertically and preventing the valve core 613 from hitting the inner wall of the valve body 611.
[0055] Sealing rings are provided at the front end of the support sleeve 933, at the connection between the support sleeve 933 and the push rod 94, and at the connection between the support sleeve 933 and the pressurization module 6, to prevent material leakage.
[0056] When the material passes through the gap between the valve seat 612 and the valve core 613, the homogenization effect on the material is adjusted by regulating the distance between the valve seat 612 and the valve core 613. The material will be sprayed outwards from the gap between the valve seat 612 and the valve core 613. The smaller the distance between the valve seat 612 and the valve core 613, the greater the pressure of the material passing through, and the better the homogenization effect. The internal cavity pressure of the booster module 6 is atmospheric pressure. Finally, the homogenized material will flow out from the discharge port on the lower side of the booster module 6. The discharge port at the bottom of the booster module 6 is connected to the discharge pipeline.
[0057] It should be noted that the threaded connection between the handle sleeve 91 and the support sleeve 933, which pushes the push rod 94 to move the valve core 613 back and forth, makes the adjustment of the distance between the valve core 613 and the valve seat 612 more precise and stable, and prevents the push rod 94 from moving back and forth. If a cylinder is used to drive the push rod 94 back and forth, the reverse pressure exerted by the push rod 94 on the cylinder is also very large. If it exceeds the pressure that the cylinder can withstand, it will cause the push rod 94 to move back and forth, and the stability will be worse than that of the handle assembly 9. The only solution in this case is to increase the stroke of the cylinder, which will make the cylinder larger and occupy a lot of installation space. Moreover, the cylinder requires an external air source processing component, which requires electricity. However, the handle assembly 9 in this invention is completely driven by pure mechanical means and does not require electricity. Therefore, it is more stable and has higher adjustment precision than cylinder drive.
[0058] refer to Figure 1 , Figure 4 and Figure 5 To prevent excessive pressure in the discharge pipe inside the high-pressure through-hole plate 21, an explosion-proof component 8 is installed at the left end of the high-pressure through-hole plate 21 (i.e., the end furthest from the micro-orifice injection module 4). This component mainly serves to relieve pressure. The explosion-proof component 8 is mainly composed of a fixed sleeve 81, a screw 83, a torsion cylinder 82, a T-shaped pressure relief pipe 85, a compression spring 84, a T-shaped pressure relief rod 86, and a pressure relief valve seat 87. The screw 83 is located between the fixed sleeve 81 and the torsion cylinder 82, with one end fixedly connected to the torsion cylinder 82 and the other end threadedly connected to the fixed sleeve 81. There is a certain gap between the inner wall of the torsion cylinder 82 and the outer wall of the fixed sleeve 81, so that no friction occurs between the torsion cylinder 82 and the fixed sleeve 81 when the torsion cylinder 82 is rotated.
[0059] One end of the T-shaped pressure relief pipe 85 is connected to the fixed sleeve 81, and the other end is connected to the discharge channel 211 inside the high-pressure through-hole plate 21. The pressure relief valve seat 87 is located inside the high-pressure through-hole plate 21 and is connected to the discharge channel 211. The T-shaped end of the TT-shaped pressure relief rod 86 is slidably connected to the inside of the fixed sleeve 81, and the other end passes through the T-shaped end of the T-shaped pressure relief pipe 85 and is inserted into the location of the pressure relief valve seat 87. A ball 88 is provided between the end of the T-shaped pressure relief rod and the pressure relief valve seat 87. The ball 88 is mainly used to block the outlet of the pressure relief valve seat 87. The compression spring 84 is located inside the fixed sleeve 81, and its two ends abut against the screw 83 and the T-shaped end of the T-shaped pressure relief valve, respectively. Under the action of the compression spring 84, the T-shaped pressure relief rod 86 presses the ball 88 against the outlet of the pressure relief valve seat 87 to prevent material from being ejected from the discharge channel 211.
[0060] When the pressure in the discharge channel 211 within the high-pressure through-hole plate 21 is too high, exceeding the pressure that the compression spring 84 can withstand, the ball 88 will be pushed open, the T-shaped pressure relief rod 86 will move backward, and the compression spring 84 will be compressed. As a result, the material will flow out from the lower end of the T-shaped pressure relief pipe 85, thereby reducing the pressure on the discharge module 2. Of course, the pressure relief can also be adjusted by twisting the torsion cylinder 82, causing the screw 83 to rotate and compress the compression spring 84. At the same time, the compression spring 84 will exert a force on the T-shaped pressure relief rod 86, pushing the ball 88 against the outlet of the pressure relief valve seat 87. Pressure relief will only continue when the pressure in the discharge module 2 exceeds this pressure.
[0061] like Figure 1 and Figure 4 As shown, a high-pressure detection mechanism 10 for detecting the internal pressure of the discharge channel 211 is also provided on the upper surface of the high-pressure through-hole plate 21. The high-pressure detection mechanism 10 uses a high-pressure test gauge or a high-pressure device to detect the pressure of the discharge channel 211 inside the high-pressure through-hole plate 21 in real time, so as to provide data support for manually adjusting the pressure relief pressure of the explosion-proof component 8.

Any modifications that may be made by those skilled in the art to certain parts therein embody the principles of the present invention and fall within the protection scope of the present invention.
