Description

Technical Field

[0001] The invention belongs to the technical field of reactors, and in particular relates to a high-efficiency PE reactor and a control method thereof. Background Art

[0002] Reactors are broadly understood as containers for physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. Reactors are widely used in the fields of petroleum, chemical industry, rubber, pesticides, dyes, medicine and food. They are pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonization, polymerization, condensation, etc., such as reactors, reaction pots, decomposition pots, polymerization pots, etc.

[0003] In the PE reactor, if the raw material particles are large, it may affect the reaction rate and uniformity. By grinding or crushing the raw material particles, the specific surface area of ​​the raw material can be increased, so that the contact between the reactants is more sufficient, thereby improving the reaction efficiency. In some PE production processes that require high reaction speeds, proper crushing of the raw materials can significantly shorten the reaction time; smaller raw material particle size can make the physical properties of the product more uniform. For example, the PE material produced after the reaction of the ground raw materials may have better mechanical properties and transparency. For some high-end PE products, such as special materials used in the fields of medical and electronics, the particle size of the raw materials is required to be high, so grinding or crushing is required.

[0004] However, in the prior art, when the raw materials are ground or pulverized before being placed in the reactor, a separate pulverizing or grinding device is required to process the raw materials, and then the processed raw materials are collected and transferred. Although this method can also pulverize and grind the raw materials, it is easy to cause loss of raw materials during the collection and transfer process, and at the same time reduce work efficiency.

[0015] A control method for an efficient PE reactor comprises the following steps: S1. When using the reactor body, hold the handle and rotate the connecting ring to rotate the crushing box, the grinding box and the support seat, so that the upper side of the feed inlet is unobstructed. At this time, the raw materials that do not need to be ground can be added into the reactor body; S2. When the raw materials to be crushed are added into the reactor body, the connecting ring is rotated so that the crushing box is located on the upper side of the feed port. During the rotation, the output end of the driving motor is not started and there is no braking force. The crushing box is driven to rotate with the output end of the driving motor as the axis. At the same time, the grinding bevel gear and the crushing bevel gear drive the output end of the driving motor to rotate through the meshing with the conical toothed disc, and the concave positioning block in the positioning mechanism is embedded in the concave positioning seat so that the bottom of the crushing box is aligned with the feed port. Then, the locking motor in the locking mechanism is started, and the output end of the locking motor drives the driving gear to rotate, and the driving gear drives the meshing thin gear ring to rotate on the surface of the reactor body. The three thick gears drive the screw to rotate. Since the screw is threadedly connected to the annular seat and the annular plate, and the top of the screw corresponds to the threaded hole on the locking block, the screw rotates upward when it rotates and is threadedly connected to the threaded hole on the locking block to fix the crushing box, the grinding box and the support seat. At this time, the driving motor in the driving mechanism is started, and the output end of the driving motor drives the crushing bevel gear to rotate through the conical toothed disc, and then the power is transmitted through the transmission mechanism, so that the two crushing rollers rotate inward at the same time to crush the raw materials. The crushed raw materials directly fall into the reactor body through the feed port, reducing the transfer time and loss of the crushed raw materials. S3, when the raw materials to be ground are added into the reactor body, the operation of step S2 is reset, and then the connecting ring is rotated to align the grinding box with the feed inlet, and then step S2 is repeated, and the two grinding rollers are simultaneously rotated inwards through the grinding bevel gear to achieve grinding of the raw materials. The ground raw materials directly fall into the reactor body through the feed inlet, reducing the transfer time and loss of the ground raw materials; S4. After the raw materials are added, the locking mechanism and the positioning mechanism are reset, and the connecting ring is rotated again to align the sealing block with the feed port. The sealing block is then driven by the vertical moving mechanism to embed into the feed port to seal the feed port, so that a sealed reaction space is provided in the reactor body.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, a crushing box and a grinding box are arranged on the top of the reactor body, so that the raw materials can be directly crushed and ground in the reactor, and the crushed or ground raw materials directly fall into the reactor body through the feed port, thereby reducing the loss of raw materials caused during the collection and transfer process. There is no need to process the raw materials in a separate device and then transfer them to the reactor, which saves operation steps and time and greatly improves work efficiency.

[0017] 2. In the present invention, by means of the positioning mechanism, when the connecting ring is rotated to align the crushing box, the grinding box or the sealing block with the feed port, the concave positioning block is embedded in the concave positioning seat, thereby achieving accurate positioning, ensuring the normal operation of the device, and improving the accuracy and stability of the operation.

[0018] 3. In the present invention, the combination of the annular guide rail and the arc guide groove makes the crushing box, the grinding box and the support seat more stable during rotation and movement, thereby ensuring the position accuracy and stability of these components during operation and reducing failures and errors caused by shaking or offset.

[0019] 4. In the present invention, a cooling box is fixed on the circumferential surface of the reactor body. The reactor can be cooled through the valved water inlet pipe at the top and the valved water outlet pipe at the bottom, so as to control the reaction temperature and ensure that the reaction is carried out under suitable temperature conditions, thereby improving the safety and stability of the reaction.

[0020] 5. In the present invention, the stirring mechanism is provided, and the output end of the driving motor drives the stirring shaft A to rotate, and the driving gear on the stirring shaft A drives the driven gear meshing therewith to rotate, thereby rotating the stirring shaft B. The stirring rods on the stirring shafts A and B are staggered up and down, which can more fully stir the reaction raw materials and improve the reaction efficiency and quality.

Two oppositely distributed crushing rollers 501 are provided inside the crushing box 5 for crushing the raw materials. The upper and lower parts of the crushing box 5 are both open to facilitate the entry and discharge of the raw materials. When the raw materials need to be crushed, the raw materials are placed in the powder.

The ground raw materials directly fall into the reactor body through the feed port 101. 1, reducing the transfer time and loss of the milled raw materials. The support seat 9 is arranged on the upper side of the reactor body 1 and connected with other components to play a supporting and fixing role. The support seat 9 plays a role in supporting and connecting the crushing box 5, the grinding box 6 and other components in the device to ensure that they can work stably. The sealing block 905 is movably arranged at the lower part of the support seat 9 and connected with the vertical moving mechanism. Through the drive of the vertical moving mechanism, it can be embedded in the feed port 101 to seal the feed port 101, so that the reactor body 1 has a sealed reaction space. After the raw materials are added, the sealing block 905 moves to the feed port through the vertical moving mechanism to seal the feed port 101. 1 is sealed to ensure that the reaction is carried out in a sealed environment, thereby improving the safety and stability of the reaction. The driving mechanism is connected to the crushing box 5, the grinding box 6 and the support seat 9, so that the three can rotate to provide power for crushing and grinding. The transmission mechanism is provided with two groups, which are respectively connected to the crushing roller 501 and the grinding roller 601, so that the two can crush and grind the raw materials. The locking mechanism is used to fix the crushing box 5, the grinding box 6 and the support seat 9 to the top of the reactor body 1 to ensure that these components can work stably during the crushing and grinding process. The stirring mechanism is arranged in the reactor body 1 to achieve mixing and stirring of the reaction raw materials to make the reaction more uniform.

[0026] Specifically, each transmission mechanism includes: There are two rollers 802, both of which are rotatably connected between the inner walls of the crushing box 5, and the two ends of the two rollers 802 are movable through the two sides of the crushing box 5 and extend outwards; The two crushing rollers 501 and the grinding roller 601 are respectively fixed to the circumferential surfaces of the two rotating rollers 802 in each set of transmission mechanisms; There are two transmission gears B803, which are respectively fixed to the circumferential surfaces of the extending ends of one side of the two rotating rollers 802, and the two transmission gears B803 are meshed with each other; A transmission shaft 8 is rotatably connected to one side end of the crushing box 5; There are two transmission gears A801, which are respectively fixed to the transmission shaft 8 and the other side extension end surface of one of the rollers 802, and the two transmission gears A801 ​​are meshed with each other.

Since the two transmission gears B803 are meshed, the two rollers 802 rotate inward at the same time, driving the crushing roller 501 to crush the raw materials. The transmission principle of the grinding box 6 is consistent with that of the crushing box 5, and will not be elaborated here.

[0028] Specifically, the driving mechanism includes: The driving motor 3 is arranged on the upper side of the reactor body 1. The driving motor 3 is fixed on the external mounting member and fixed according to actual needs. The output end of the driving motor 3 rotates, the body is fixed, and the output end of the driving motor 3 moves through the reactor body 1. The conical toothed disc 301 is fixed to the output end surface of the reactor body 1; The crushing bevel gear 302 is fixedly connected to the circumferential surface of the transmission shaft 8 connected to the crushing box 5, and the crushing bevel gear 302 is obliquely meshed with the conical toothed disc 301; The bevel grinding gears 303 are fixedly connected to the circumferential surface of the transmission shaft 8 connected to the grinding box 6, and the bevel grinding gears 303 are all obliquely meshed with the conical toothed disc 301; A fixing ring 4 is fixed to the top of the reactor body 1; The annular groove 401 is formed on the circumferential surface of the fixing ring 4; The annular block 402 is rotatably connected in the annular groove 401; There are three connecting blocks 403 , one end of each of which is fixed to the circumferential surface of the annular block 402 , and the other end of each of which is fixed to the end of the crushing box 5 , the grinding box 6 and the support seat 9 .

At the same time, the cooperation of the fixing ring 4, the annular groove 401, the annular block 402 and the connecting block 403 ensures that the crushing box 5, the grinding box 6 and the support seat 9 can rotate stably.

[0030] Specifically, the vertical movement mechanism includes: A driving port 901 is provided at one side end of the support seat 9; There are two screw rods 902, one end of each of which is rotatably connected to the bottom wall of the driving port 901, and the other end of each of which is movable through the top of the support seat 9 and extends upward; Nut blocks 903, two of which are provided and are respectively threadedly connected to the circumferential surfaces of the two screw rods 902; Slide rods 904, of which multiple ones are provided, one end of each of the slide rods 904 is fixed to the bottom of the two nut blocks 903, and the other end of each of the slide rods 904 is movable through the bottom of the support seat 9 and fixed to the sealing block 905; Adjust the slave gear 908, which is provided with two and is respectively fixed to the circumferential surface of the extending ends of the two screw rods 902; The adjusting shaft 906 is rotatably connected to the top of the supporting seat 9; The adjusting main gear 907 is fixed to the circumferential surface of the adjusting shaft 906 , and the adjusting main gear 907 is meshedly connected with the two adjusting slave gears 908 .

[0031] In this embodiment: the vertical moving mechanism cooperates with components such as the screw rod 902, the nut block 903, and the slide rod 904. When the adjusting shaft 906 rotates, it drives the adjusting main gear 907 to rotate, and then the adjusting slave gear 908 rotates, so that the screw rod 902 rotates, the nut block 903 moves on the screw rod 902, and drives the sealing block 905 to move up and down linearly through the slide rod 904, thereby realizing the sealing and opening operations of the feed port 101.

[0032] Specifically, the locking mechanism includes: The annular seat 11 is fixed to the circumferential surface of the reactor body 1; The screw rods 15 are provided with three screw rods 15, which are evenly threadedly connected to the top of the annular seat 11, and the three screw rods 15 are threadedly penetrated to the top of the annular plate 2; Thick gears 14, of which three are provided and are fixed to the circumferential surfaces of the three screw rods 15 respectively; A thin gear ring 16 is rotatably connected to the circumferential surface of the reactor body 1 and meshes with the three thick gears 14; The locking motor 12 is fixed to the bottom of the annular seat 11, and the output end of the locking motor 12 movably penetrates the top of the annular seat 11 and extends upward; The driving gear 13 is fixed to the output end surface of the locking motor 12 and meshes with the thin gear ring 16; There are three locking blocks 7 , which are respectively fixed to the crushing box 5 , the grinding box 6 and the end of the support base 9 away from the driving motor 3 , and the tops of the three locking blocks 7 are all provided with threaded holes matching the screw rod 15 .

The thickness of the thin gear ring 16 is greater than the thickness of the thin gear ring 16, so that when the screw 15 moves, the thin gear ring 16 and the thin gear ring 16 will not be out of meshing state, thereby rotating the screw 15. Since the screw 15 is threadedly connected to the annular seat 11 and the annular plate 2, and matches the threaded hole on the locking block 7, the screw 15 rotates upward when it rotates and is threadedly connected to the threaded hole on the locking block 7, thereby fixing the crushing box 5, the grinding box 6 and the support seat 9.

[0042] The working principle and use process of the present invention: A control method for a high-efficiency PE reactor comprises the following steps: S1. When using the reactor body 1, the connecting ring 19 is rotated by holding the handle 191 to rotate the crushing box 5, the grinding box 6 and the support seat 9, so that the upper side of the feed inlet 101 is not blocked. At this time, the raw materials that do not need to be ground can be added into the reactor body 1; S2. When the raw materials to be crushed are added into the reactor body 1, the connecting ring 19 is rotated so that the crushing box 5 is located on the upper side of the feed port 101. During the rotation, the output end of the driving motor 3 is not started and there is no braking force. The crushing box 5 is driven to rotate with the output end of the driving motor 3 as the axis. At the same time, the grinding bevel gear 303 and the crushing bevel gear 302 drive the output end of the driving motor 3 to rotate by meshing with the conical toothed disc 301, and the concave positioning block 192 in the positioning mechanism is embedded in the concave positioning seat 193 so that the bottom of the crushing box 5 is aligned with the feed port 101. Then, the locking motor 12 in the locking mechanism is started, and the output end of the locking motor 12 drives the driving gear 13 to rotate, and the driving gear 13 drives the meshing thin gear ring 16 in the reactor body 1 The surface of the gear 14 rotates, so that the three thick gears 14 drive the screw 15 to rotate. Since the screw 15 is threadedly connected to the annular seat 11 and the annular plate 2, and the top of the screw 15 corresponds to the threaded hole on the locking block 7, the screw 15 rotates upward when it rotates and is threadedly connected to the threaded hole on the locking block 7, so as to fix the crushing box 5, the grinding box 6 and the support seat 9. At this time, the driving motor 3 in the driving mechanism is started, and the output end of the driving motor 3 drives the crushing bevel gear 302 to rotate through the conical toothed disc 301, and then the power is transmitted through the transmission mechanism, so that the two crushing rollers 501 rotate inward at the same time to realize the crushing of the raw materials. The crushed raw materials directly fall into the reactor body 1 through the feed port 101, reducing the transfer time and loss of the crushed raw materials; S3, when the raw material to be ground is added into the reactor body 1, the operation of step S2 is reset, and then the connecting ring 19 is rotated to align the grinding box 6 with the feed inlet 101, and then step S2 is repeated, and the two grinding rollers 601 are simultaneously rotated inward by the grinding bevel gear 303 to grind the raw material, and the ground raw material directly falls into the reactor body 1 through the feed inlet 101, thereby reducing the transfer time and loss of the ground raw material; S4. After the raw materials are added, the locking mechanism and the positioning mechanism are reset, and the connecting ring 19 is rotated again to align the sealing block 905 with the feed port 101. Then, the sealing block 905 is driven by the vertical moving mechanism to be embedded in the feed port 101 to seal the feed port 101, so that there is a sealed reaction space in the reactor body 1.

When the reactor body (1) is in use, the connecting ring (19) is rotated by holding the handle (191) to rotate the crushing box (5), the grinding box (6) and the support seat (9), so that the upper side of the feed inlet (101) is not blocked. At this time, raw materials that do not need to be ground can be added into the reactor body (1); S2. When raw materials to be crushed are added into the reactor body (1), the connecting ring (19) is rotated so that the crushing box (5) is located on the upper side of the feed port (101). During the rotation, the output end of the driving motor (3) is not started and there is no braking force. The crushing box (5) is driven to rotate with the output end of the driving motor (3) as the axis. At the same time, the grinding bevel gear (303) and the crushing bevel gear (302) drive the output end of the driving motor (3) to rotate by meshing with the conical toothed disc (301).

At this time, the drive motor (3) in the drive mechanism is started, and the output end of the drive motor (3) drives the crushing bevel gear (302) to rotate through the conical toothed disc (301), and then the power is transmitted through the transmission mechanism, so that the two crushing rollers (501) rotate inward at the same time to crush the raw materials. The crushed raw materials directly fall into the reactor body (1) through the feed port (101), thereby reducing the transfer time and loss of the crushed raw materials. S3. When the raw material to be ground is added into the reactor body (1), the operation of step S2 is reset, and then the connecting ring (19) is rotated so that the grinding box (6) is aligned with the feed port (101), and then step S2 is repeated, and the two grinding rollers (601) are simultaneously rotated inwardly through the grinding bevel gear (303) to grind the raw material. The ground raw material directly falls into the reactor body (1) through the feed port (101), thereby reducing the transfer time and loss of the ground raw material; S4. After the raw materials are added, the locking mechanism and the positioning mechanism are reset, and the connecting ring (19) is rotated again to align the sealing block (905) with the feed port (101). The sealing block (905) is then driven by the vertical moving mechanism to be embedded in the feed port (101) to seal the feed port (101), so that a sealed reaction space is provided in the reactor body (1).
