Description

Technical Field

[0001] The invention relates to the technical field of chemical reactors, in particular to a reactor for safe production of chemical industry. Background Art

[0002] A reactor for safe chemical production is a pressure vessel specially designed to improve the safety and efficiency in the chemical production process.

[0003] In order to facilitate the cleaning of crystallized or condensed block products on the inner wall, existing chemical reactors are mostly equipped with scraper cleaning components. However, the scraper components are mostly arranged in a form of long-term scraping contact with the inner wall of the reactor, resulting in excessive wear between the scraper components and the inner wall of the reactor, thereby reducing the service life of the scraper components and the inner wall of the reactor. In addition, although some scraper components are arranged in the form of sliding and retractable spaces to avoid excessive wear, the sliding and retracting operation is relatively troublesome and inconvenient, and the reactor needs to be shut down to open the reactor and reach into the reactor to implement it. In addition, the reactor needs to be opened as a whole to remove the scraper component for maintenance or replacement. The removal operation of the scraper component is relatively troublesome and inefficient, which is not conducive to the quick and convenient maintenance and replacement of the scraper component. Summary of the invention

[0004] In view of this, the present invention provides a reactor for safe production of chemical industry to solve the problem that the sliding and retracting operation of the scraper assembly is troublesome and inconvenient, and the reactor needs to be shut down to open and the hands need not be inserted into the reactor to be implemented.

[0005] The technical solution proposed by the present invention is: a reactor for chemical safety production, specifically comprising: a reactor shell, wherein an upper cover is threadedly fastened to the top opening of the reactor shell;

[0006] A rotating shaft sleeve is rotatably installed through the center of the upper cover, and the rotating shaft sleeve is inserted into the interior of the reactor shell; a driving rod is rotatably installed through the rotating shaft sleeve, and a driven gear is sleeved on the top part of the rotating shaft sleeve; three positioning holes are arranged around and spaced on the driven gear; a T-shaped positioning rod is slidably installed through the top part of the driving rod through the spring push, and the bottom end of the vertical support rod section of the T-shaped positioning rod is plugged and matched with the positioning hole;

[0007] Two horizontal stirring shafts are symmetrically welded at the middle position of the rotating shaft sleeve, and two symmetrically arranged horizontal stirring shafts are rotatably installed in the bottom side space inside the reactor shell, and two symmetrically arranged strip-shaped mounting rods are slidably installed on the four horizontal stirring shafts, and scraping strips are slidably inserted on the two strip-shaped mounting rods; two Z-shaped limit rods are symmetrically welded on the rotating shaft sleeve above the horizontal stirring shaft; a force transmission plate is welded at the bottom end of the driving rod, and the force transmission plate is arranged in a twisted and inclined manner; two connecting rods are symmetrically rotatably connected between the force transmission plate and the two strip-shaped mounting rods; under normal conditions, the top ends of the two scraping strips are in contact with the L-shaped rod sections at the head ends of the two Z-shaped limit rods;

[0008] Two inspection pipes are symmetrically welded on the upper cover at both sides of the rotating shaft sleeve. When the two strip-shaped mounting rods slide close to the rotating shaft sleeve, they are directly opposite to the two inspection pipes up and down.

[0009] Furthermore,

[0010] Two handles are symmetrically welded to the top of the driving rod, and an L-shaped support rod is welded to the bottom side of one of the handles. The vertical support part of the T-shaped positioning rod is pushed by a spring to slide through and fit with the horizontal part of the L-shaped support rod and the handle connected to the L-shaped support rod.

[0011] Furthermore,

[0012] A T-shaped rotating seat is welded between the middle sections of the two horizontal stirring shafts at the lower side, and a lower cover is threadedly fastened to the bottom opening of the reactor shell, a U-shaped supporting frame is welded at the center of the top of the lower cover, and the T-shaped rotating seat is rotatably matched with the middle part of the T-shaped rotating seat;

[0013] A waste slag discharge pipe is welded at the center position of the bottom side of the lower cover.

[0014] Furthermore,

[0015] The strip-shaped mounting rod is provided with a T-shaped mounting groove with a bottom end for blocking, and the cross section of the scraper strip is a T-shaped structure, and the scraper strip is slidably matched with the T-shaped mounting groove;

[0016] A force plate is welded to the top of the strip-shaped mounting rod, the force plate abuts against the L-shaped rod section at the head end of the Z-shaped limiting rod, and an open slot is formed between the force plate and the top of the strip-shaped mounting rod.

[0017] Furthermore,

[0018] Two T-shaped sliders are symmetrically welded on one side of the strip-shaped mounting rod close to the rotating shaft sleeve. The two T-shaped sliders are located on the upper and lower ends of the strip-shaped mounting rod. The two T-shaped sliders are respectively slidably matched with the two horizontal stirring shafts on the upper side and the two horizontal stirring shafts on the lower side;

[0019] The top end portion of the strip-shaped mounting rod is slidably located between two horizontal stirring shafts at the upper side, and the bottom end portion is slidably located between two horizontal stirring shafts at the lower side.

[0020] Furthermore,

[0021] The two T-shaped sliding blocks at the upper side are directly welded and fixed to the two strip-shaped mounting rods.

[0022] Furthermore,

[0023] A driving device is fixedly installed on the upper cover, a driving gear is sleeved on the bottom end of the power output shaft of the driving device, and a chain is tensionedly sleeved between the driving gear and the driven gear.

[0024] Furthermore,

[0025] The top ends of the two strip-shaped mounting rods are both welded with rod sleeves, and the two T-shaped sliding blocks on the upper side are welded and fixed together with the two rod sleeves;

[0026] L-shaped push plates are slidably installed through the two rod sleeves, and the top horizontal parts of the two L-shaped push plates are correspondingly plugged and matched with the two open slots.

[0027] Furthermore,

[0028] A set of second pull rods are rotatably connected to the two strip-shaped mounting rods below the rod sleeves, and first pull rods are rotatably connected between the two sets of second pull rods and the bottom ends of the two L-shaped push plates. Normally, the two first pull rods and the two sets of second pull rods present a triangular arch structure.

[0029] When the two strip-shaped installation rods slide toward each other, the two first pull rods in the arched state and the two groups of second pull rods are in abutment contact with the rotating shaft sleeve.

[0030] The present invention provides a reactor for chemical safety production, which has the following beneficial effects:

[0031] According to the present invention, under normal conditions, the two scraping strips slide and separate from the circumferential inner wall of the reactor shell. Compared with the prior art, this avoids excessive wear caused by the scraping strips being in long-term frictional and sliding contact with the circumferential inner wall of the reactor shell, which helps to increase and extend the service life of the scraping strips and the reactor shell. When the two scraping strips and the two bar-shaped mounting rods are in a state of being separated from the circumferential inner wall of the reactor shell, they can be used as vertical stirring components, which has a dual-purpose effect and can save the need for additional vertical stirring components to be arranged between the upper and lower four horizontal stirring shafts, which helps to simplify the overall stirring structure of the reactor.

[0032] In addition, the top end of the driving rod passes through the protruding shaft sleeve and the upper cover and is placed above the top end of the upper cover. This allows the staff to directly hold and twist the driving rod outside the reactor to drive the two bar-shaped mounting rods and the two scraping strips to extend and slide, and switch between the empty position and the cleaning use state, without opening the reactor as a whole, without stopping the reactor, and without putting their hands into the reactor. Compared with the existing technology, the operation is simpler and more efficient, avoiding collisions or other forms of injuries to the hands, and helping to improve the safety of the operation and use of the reactor.

[0033] In addition, the torsion of the driving rod drives the two strip mounting rods to slide significantly closer to each other. When approaching the rotating shaft sleeve, the two strip mounting rods separate from the L-shaped rod sections at the head ends of the two Z-shaped limit rods, slide into the empty space inside the long rod sections of the two Z-shaped limit rods, and face the two inspection pipes up and down. At this time, the top covers of the two inspection pipes are opened, and the two scrapers can be directly pulled out from the two strip mounting rods and the inside of the reactor shell for maintenance or replacement. Compared with the prior art, the two scrapers can be removed without opening the reactor as a whole. The removal operation of the two scrapers is convenient and efficient, which helps to indirectly improve the maintenance and replacement efficiency of the two scrapers.

[0034] In addition, after the T-shaped positioning rod has inserted and positioned the driving rod, the force transmission plate is also positioned together. After being positioned together, the force transmission plate can rotate together with the two strip mounting rods. Since the force transmission plate is arranged in a torsionally inclined manner, it can implement rotational cutting on the liquid chemical raw materials inside the reactor shell when it rotates, and produce a rotational pumping effect on the liquid chemical raw materials. In this way, the force transmission plate can draw and guide the liquid chemical raw materials in the bottom layer of the reactor shell upward. This, together with the four horizontal stirring shafts and the two strip mounting rods, can implement complex and sufficient stirring of the chemical raw materials in the reactor shell, which helps to promote the reaction of the chemical raw materials.

[0035] In addition, the force transmission plate can be used as a power transmission component between the driving rod and the two strip mounting rods, and can also be used as a component for rotating and pumping chemical raw materials. It has the effect of a dual-purpose device, eliminating the need for additional rotating and pumping components inside the reactor shell, and helps to further simplify the overall stirring structure of the reactor.

[0036] In addition, the top horizontal part of the L-shaped push plate is in contact with the force plate. The L-shaped push plate can slide upward to lift the scraper bar in the T-shaped mounting groove of the strip mounting rod, and lift the scraper bar into the inspection pipe for direct grasping and extraction by hand. This saves the trouble of having to put the hand into the reactor shell to extract the scraper bar, and helps to further simplify the operation steps of removing the scraper bar.

[0037] In addition, when the two strip-shaped mounting rods are driven close to the rotating shaft sleeve to remove the two scraper strips, the arched parts of the two first pull rods and the two sets of second pull rods can be pushed toward each other, and the two scraper strips can be automatically lifted into the two maintenance pipes. This saves the trouble of manually lifting the two scraper strips into the two maintenance pipes, and helps to further simplify the removal operation steps of the two scraper strips.

[0057] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0058] Please refer to Figures 1 to 8 , Embodiment 1:

[0059] The present invention proposes a reactor for safe production of chemical industry, comprising: a reactor shell 1, an upper cover 101, a lower cover 102, a waste slag discharge pipe 103, a maintenance pipe 104, a U-shaped support frame 105, a liquid inlet pipe 106, a liquid outlet pipe 107, a driving device 2, a driving rod 3, a handle bar 301, an L-shaped support rod 302, a force transmission plate 303, a connecting rod 304, a T-shaped positioning rod 305, a rotating shaft sleeve 4, a driven gear 401, a Z-shaped limiting rod 402, a strip-shaped mounting rod 5, a scraper bar 501, a force plate 5011, a T-shaped sliding block 502, a horizontal stirring shaft 6, and a T-shaped rotating seat 601. The upper cover 101 is threadedly fastened on the top opening of the reactor shell 1;

[0060] Among them, a rotating shaft sleeve 4 is rotatably installed through the center position of the upper cover 101, and the rotating shaft sleeve 4 is extended and inserted into the interior of the reactor shell 1; a driving rod 3 is rotatably installed on the rotating shaft sleeve 4, and a driven gear 401 is sleeved on the top part of the rotating shaft sleeve 4; three positioning holes are arranged around and spaced apart on the driven gear 401; a T-shaped positioning rod 305 is slidably installed through the top part of the driving rod 3 through the spring push, and the bottom end of the vertical support rod section of the T-shaped positioning rod 305 is plugged into the positioning hole; two horizontal stirring shafts 6 are symmetrically welded at the middle position of the rotating shaft sleeve 4, and two symmetrically arranged horizontal stirring shafts 6 are rotatably installed in the bottom side space inside the reactor shell 1, and two symmetrically arranged strip-shaped mounting rods 5 are slidably installed on the four horizontal stirring shafts 6, and scraping strips 501 are slidably inserted on the two strip-shaped mounting rods 5; two Z-shaped limit rods 402 are symmetrically welded on the rotating shaft sleeve 4 above the horizontal stirring shaft 6; The force plate 303 and the force transmission plate 303 are arranged in a twisted and tilted manner; the force transmission plate 303 and the two strip-shaped mounting rods 5 are symmetrically connected to each other by two connecting rods 304; under normal conditions, the top ends of the two scraping strips 501 are in contact with the L-shaped rod sections at the head ends of the two Z-shaped limiting rods 402; two inspection pipes 104 are symmetrically welded on both sides of the rotating shaft sleeve 4 on the upper cover 101, and when the two strip-shaped mounting rods 5 slide close to the rotating shaft sleeve 4, they are directly opposite to the two inspection pipes 104 up and down; the upper cover 101 A driving device 2 is fixedly installed on the top, and a driving gear is sleeved on the bottom end of the power output shaft of the driving device 2. A chain is tensioned between the driving gear and the driven gear 401. The driving device 2 is composed of a motor and a reducer. The two horizontal stirring shafts 6 at the lower side are not in direct contact with the rotating shaft sleeve 4, and do not directly receive the rotating driving force of the rotating shaft sleeve 4. Its function is to stabilize the two strip-shaped mounting rods 5 to ensure that the strip-shaped mounting rods 5 and the two scraping strips 501 rotate stably inside the reactor shell 1.

[0061] The chain drive device 2 can rotatably drive the rotating shaft sleeve 4, the four horizontal stirring shafts 6 and the two strip-shaped mounting rods 5 to stir the chemical raw materials inside the reactor shell 1; the two scraping strips 501 are slidably mounted on the four horizontal stirring shafts 6 through the two strip-shaped mounting rods 5, and when they slide away from each other and abut against the inner wall of the circumference of the reactor shell 1, they can follow the rotation of the two strip-shaped mounting rods 5 to scrape and clean the crystal blocks or condensed blocks attached to the inner wall of the circumference of the reactor shell 1, and under normal conditions, the two scraping strips 501 slide and separate from the inner wall of the circumference of the reactor shell 1 (refer to Figure 3 ), compared with the prior art, it avoids excessive wear caused by the scraper strip 501 in long-term friction and sliding contact with the circumferential inner wall of the reactor shell 1, which helps to extend the service life of the scraper strip 501 and the reactor shell 1; when the two scraper strips 501 and the two strip-shaped mounting rods 5 are separated from the circumferential inner wall of the reactor shell 1 (refer to Figure 3), can be used as a vertical stirring component, having a dual-purpose use effect, and can save the need for additional vertical stirring components between the upper and lower horizontal stirring shafts 6, which helps to simplify the overall stirring structure of the reactor;

[0062] The L-shaped rod sections at the head ends of the two Z-shaped limit rods 402 are used to block and limit the two scraping strips 501 on the two strip-shaped mounting rods 5 when in stirring and cleaning use; the two connecting rods 304, the force transmission plate 303, the two strip-shaped mounting rods 5 and the driving rod 3 are connected together to form two crank slider mechanisms, through which the reciprocating torsion driving rod 3 can drive the driving rod 3 and the rotating shaft sleeve 4 to rotate relative to each other, drive and control the two strip-shaped mounting rods 5 and the two scraping strips 501 to slide inward and outward, which is convenient for cleaning and emptying. The top end of the driving rod 3 penetrates and protrudes from the rotating shaft sleeve 4 and the upper cover 101, and is placed above the top end of the upper cover 101. This allows the staff to directly hold and twist the driving rod 3 outside the reactor to drive the two strip-shaped mounting rods 5 and the two scraping strips 501 to telescope and slide, and switch between the empty position and the cleaning use state. Compared with the prior art, the operation is simpler, more efficient and more effective.

[0063] The driving rod 3 is twisted to drive the two strip-shaped mounting rods 5 to slide toward each other greatly. When approaching the rotating shaft sleeve 4, the two strip-shaped mounting rods 5 are separated from the L-shaped rod sections at the head ends of the two Z-shaped limiting rods 402, and slide into the empty space inside the long rod sections of the two Z-shaped limiting rods 402, and face the two inspection pipes 104 up and down. At this time, the top covers of the two inspection pipes 104 are opened, and the two scraping strips 501 can be directly pulled out from the two strip-shaped mounting rods 5 and the inside of the reactor shell 1 for maintenance or replacement. Compared with the prior art, the two scraping strips 501 can be removed without opening the reactor as a whole. The removal operation of the two scraping strips 501 is convenient and efficient, which helps to indirectly improve the maintenance and replacement efficiency of the two scraping strips 501.

[0064] When the two strip mounting rods 5 are driven to slide close to the rotating shaft sleeve 4, the top ends of the two Z-shaped limiting rods 402 are disengaged from the L-shaped rod sections at the head ends of the two Z-shaped limiting rods 402, releasing the limits on the two scraper strips 501, which saves the trouble of manually releasing the limits of the two scraper strips 501, helps to simplify the removal operation steps of the two scraper strips 501, and the two scraper strips 501 are taken out for maintenance or replacement and then slidably inserted into the two strip mounting rods 5, and when the two strip mounting rods 5 are driven to slide away from each other and reset, the top ends of the two strip mounting rods 5 slide against the bottom sides of the L-shaped rod sections at the head ends of the two Z-shaped limiting rods 402, restoring the limits on the two scraper strips 501, which saves the trouble of manually restoring the limits of the two scraper strips 501, helps to simplify the assembly steps of the two scraper strips 501, and is easy to operate and saves time.

[0065] The T-shaped positioning rod 305 is selected to be plugged into the three positioning holes (refer to Figure 6 ), the driving rod 3 can be inserted and positioned, so that the two scraper strips 501 are kept in the three use positions of external sliding cleaning, internal sliding empty position and internal sliding disassembly; after the T-shaped positioning rod 305 inserts and positions the driving rod 3, the force transmission plate 303 is also positioned together, and the force transmission plate 303 after being positioned can rotate with the two strip-shaped mounting rods 5. Since the force transmission plate 303 is arranged in a twisted and inclined manner, it can implement rotary cutting on the liquid chemical raw materials inside the reactor shell 1 when it rotates, and produce a rotary pumping effect on the liquid chemical raw materials. In this way, the force transmission plate 303 can suck and guide the liquid chemical raw materials in the bottom layer of the reactor shell 1 upward, which, together with the four horizontal stirring shafts 6 and the two strip-shaped mounting rods 5, can implement complex and sufficient stirring of the chemical raw materials in the reactor shell 1, which helps to promote the reaction of the chemical raw materials;

[0066] The force transfer plate 303 can be used as a power transmission component between the driving rod 3 and the two strip mounting rods 5, and can also be used as a component for rotating and pumping chemical raw materials. It has the effect of a dual-purpose device, eliminates the need for additional rotating and pumping components inside the reactor shell 1, and helps to further simplify the overall stirring structure of the reactor.

[0067] Preferably,

[0068] Two handle bars 301 are symmetrically welded to the top of the driving rod 3, and an L-shaped support rod 302 is welded to the bottom side of one of the handle bars 301. The vertical support part of the T-shaped positioning rod 305 is pushed by a spring to slide through the horizontal part of the L-shaped support rod 302 and the handle bar 301 connected to the L-shaped support rod 302.

[0069] Preferably,

[0070] A T-shaped rotating seat 601 is welded between the middle sections of the two horizontal stirring shafts 6 at the lower side, and a lower cover 102 is threadedly fastened to the bottom opening of the reactor shell 1, and a U-shaped support frame 105 is welded at the top center of the lower cover 102, and the T-shaped rotating seat 601 is rotatably matched with the middle part of the T-shaped rotating seat 601; a waste slag discharge pipe 103 is welded at the bottom center of the lower cover 102;

[0071] The slag cleaned from the circumferential side wall of the reactor shell 1 is discharged through the waste slag discharge pipe 103.

[0072] Preferably,

[0073] A T-shaped mounting groove with a sealing arrangement at the bottom end is provided on the strip mounting rod 5, and the cross-section of the scraper strip 501 is a T-shaped structure, and the scraper strip 501 slides in cooperation with the T-shaped mounting groove; a force plate 5011 is welded to the top end of the strip mounting rod 5, and the force plate 5011 abuts against the L-shaped rod section at the head end of the Z-shaped limiting rod 402, and an open slot is formed between the force plate 5011 and the top end of the strip mounting rod 5; the force plate 5011 can be conveniently grasped by hand to implement upward sliding extraction of the scraper strip 501.

[0074] Preferably,

[0075] Two T-shaped sliders 502 are symmetrically welded on one side of the strip mounting rod 5 close to the rotating shaft sleeve 4. The two T-shaped sliders 502 are located on the upper and lower end parts of the strip mounting rod 5. The two T-shaped sliders 502 are respectively slidably matched with the two horizontal stirring shafts 6 on the upper side and the two horizontal stirring shafts 6 on the lower side; the top part of the strip mounting rod 5 is slidably located between the two horizontal stirring shafts 6 on the upper side, and the bottom part is slidably located between the two horizontal stirring shafts 6 on the lower side; the two T-shaped sliders 502 on the upper side are directly welded and fixed to the two strip mounting rods 5.

[0076] Preferably, three liquid inlet pipes 106 are welded at intervals on the upper cover 101, and a liquid outlet pipe 107 is welded on the bottom side of the circumferential outer wall of the reactor shell 1. The three liquid inlet pipes 106 are used to add liquid chemical raw materials into the reactor shell 1, and the liquid outlet pipe 107 is used to discharge the chemical raw materials after sufficient reaction.

[0077] It is worth noting that the through-rotating gap between the driving rod 3 and the rotating shaft sleeve 4 is sealed by elastic sealing members such as packing. The use of packing to seal the through-rotating gap of shafts is a prior art and is widely used in valves to seal valve shafts. When applying the packing in the present invention, those skilled in the art may refer to the specific implementation method of the packing on the valve, so it will not be described in detail.

[0078] On the basis of the first embodiment, the second embodiment, as Figures 7 to 9 As shown:

[0079] The present invention provides a reactor for chemical safety production, comprising an L-shaped push plate 503, a first pull rod 504, a second pull rod 505, and a rod sleeve 506. The top parts of the two strip-shaped installation rods 5 are welded with the rod sleeves 506, and the two T-shaped sliders 502 on the upper side are welded and fixed together with the two rod sleeves 506; the two rod sleeves 506 are both penetrated and slidably installed with L-shaped push plates 503, and the top horizontal parts of the two L-shaped push plates 503 are correspondingly plugged and matched with the two open slots;

[0080] The top horizontal part of the L-shaped push plate 503 is in contact with the force plate 5011. The L-shaped push plate 503 can slide upward to lift the scraper 501 in the T-shaped mounting groove of the strip mounting rod 5, and lift the scraper 501 into the inspection pipe 104 for direct grasping and extraction by hand. Compared with the first embodiment, the trouble of inserting the hand into the reactor shell 1 to extract the scraper 501 can be saved, which helps to further simplify the removal operation steps of the scraper 501.

[0081] Preferably,

[0082] A set of second pull rods 505 are rotatably connected to the two strip-shaped installation rods 5 below the rod sleeves 506, and a first pull rod 504 is rotatably connected between the two sets of second pull rods 505 and the bottom ends of the two L-shaped push plates 503. Normally, the two first pull rods 504 and the two sets of second pull rods 505 present a triangular arched structure; when the two strip-shaped installation rods 5 slide close to each other, the two first pull rods 504 and the two sets of second pull rods 505 in the arched state are in contact with the rotating shaft sleeve 4;

[0083] The two first pull rods 504, the two groups of second pull rods 505 and the two L-shaped push plates 503 are connected together to form two multi-link driving mechanisms. Through these two mechanisms, the two first pull rods 504 and the two groups of second pull rods 505 are pushed toward each other to expand the two first pull rods 504 and the two groups of second pull rods 505, which can drive the two L-shaped push plates 503 to slide upward, providing an upward driving force for the two scraper strips 501, and when the two bar-shaped mounting rods 5 are driven close to the rotating shaft sleeve 4 to remove the two scraper strips 501, the arched parts of the two first pull rods 504 and the two groups of second pull rods 505 can be pushed toward each other to automatically lift the two scraper strips 501 into the two inspection pipes 104, which saves the trouble of manually lifting the two scraper strips 501 into the two inspection pipes 104, and helps to further simplify the removal operation steps of the two scraper strips 501.

[0084] It is worth noting that when removing the two scraper strips 501 , the two strip-shaped mounting rods 5 need to be rotated and adjusted so that the two strip-shaped mounting rods 5 and the two inspection pipes 104 are located on the same horizontal line and aligned.

[0085] Working principle: three liquid inlet pipes 106 are used to add liquid chemical raw materials into the reactor shell 1, and the liquid outlet pipe 107 is used to discharge the chemical raw materials after sufficient reaction. The chain drive device 2 can rotate and drive the rotating shaft sleeve 4 and the four horizontal stirring shafts 6 and the two strip-shaped mounting rods 5 to stir the chemical raw materials inside the reactor shell 1. The two scraping strips 501 are slidably mounted on the four horizontal stirring shafts 6 through the two strip-shaped mounting rods 5. When they slide away from each other and come into contact with the circumferential inner wall of the reactor shell 1, they can rotate with the two strip-shaped mounting rods 5 to scrape and clean the crystal blocks or agglomerated blocks attached to the circumferential inner wall of the reactor shell 1. The slag cleaned from the circumferential side wall of the reactor shell 1 is discharged through the waste slag discharge pipe 103; under normal conditions, the two scraping strips 501 slide and separate from the circumferential inner wall of the reactor shell 1 (refer to Figure 3 ), when the two scraper strips 501 and the two strip-shaped mounting rods 5 are separated from the inner wall of the reactor shell 1 (refer to Figure 3 ), which can be used as an upright stirring component; the L-shaped rod sections at the head ends of the two Z-shaped limit rods 402 are used to block and limit the two scraping strips 501 on the two strip-shaped mounting rods 5 in the stirring and cleaning use state; the two connecting rods 304, the force transmission plate 303, the two strip-shaped mounting rods 5 and the driving rod 3 are connected together to form two crank slider mechanisms, through which the reciprocating torsion driving rod 3 can drive the driving rod 3 and the rotating shaft sleeve 4 to rotate relative to each other, drive and control the two strip-shaped mounting rods 5 and the two scraping strips 501 to slide inward and outward, and freely switch between the cleaning and empty use states;

[0086] The driving rod 3 is twisted to drive the two strip-shaped mounting rods 5 to slide towards each other. When approaching the rotating shaft sleeve 4, the two strip-shaped mounting rods 5 are separated from the L-shaped rod sections at the head ends of the two Z-shaped limiting rods 402, and slide into the empty space inside the long rod sections of the two Z-shaped limiting rods 402, and face the two inspection pipes 104 up and down. At this time, the top covers of the two inspection pipes 104 are opened, and the two scraping strips 501 can be directly pulled out from the two strip-shaped mounting rods 5 and the inside of the reactor shell 1 for maintenance or replacement; the T-shaped positioning rod 305 is selected to be plugged into and matched with the three positioning holes (refer to Figure 6 ), the driving rod 3 can be inserted and positioned so that the two scraper strips 501 are kept in three use positions: outer sliding cleaning, inner sliding empty position, and inner sliding disassembly and assembly;

[0087] When the two strip-shaped mounting rods 5 are driven to slide close to the rotating shaft sleeve 4, the top ends are disengaged from the L-shaped rod sections at the head ends of the two Z-shaped limiting rods 402, thereby releasing the limit on the two scraping strips 501; after the two scraping strips 501 are taken out for repair or replacement, they are slidably inserted on the two strip-shaped mounting rods 5 again, and when the two strip-shaped mounting rods 5 are driven to slide away from each other and reset, the top ends of the two strip-shaped mounting rods 5 slide against the bottom sides of the L-shaped rod sections at the head ends of the two Z-shaped limiting rods 402, thereby restoring the limit on the two scraping strips 501;

[0088] After the T-shaped positioning rod 305 inserts and positions the driving rod 3, the force transmission plate 303 is also positioned. The force transmission plate 303 after being positioned can rotate together with the two strip-shaped mounting rods 5. Since the force transmission plate 303 is arranged in a twisted and inclined manner, it can implement rotary cutting on the liquid chemical raw materials inside the reactor shell 1 when rotating, and produce a rotary pumping effect on the liquid chemical raw materials. In this way, the force transmission plate 303 can suck and guide the liquid chemical raw materials in the bottom layer of the reactor shell 1 upward, which can be used together with the four horizontal stirring shafts 6 and the two strip-shaped mounting rods 5 to implement a composite and sufficient stirring of the chemical raw materials in the reactor shell 1.

[0089] The top horizontal part of the L-shaped push plate 503 abuts against the force plate 5011, and the L-shaped push plate 503 slides upward to lift the scraper strip 501 in the T-shaped mounting groove of the strip mounting rod 5, and lifts the scraper strip 501 into the inspection pipe 104 for direct grasping and extraction by hand;

[0090] The two first tie rods 504, the two sets of second tie rods 505 and the two L-shaped push plates 503 are connected together to form two multi-link driving mechanisms. Through these two mechanisms, the two first tie rods 504 and the two sets of second tie rods 505 that are arched are pushed toward each other to unfold the two first tie rods 504 and the two sets of second tie rods 505, which can drive the two L-shaped push plates 503 to slide upward, providing an upward driving force for the two scraper strips 501. When the two bar-shaped mounting rods 5 are driven close to the rotating shaft sleeve 4 to dismantle the two scraper strips 501, the arched parts of the two first tie rods 504 and the two sets of second tie rods 505 can be pushed toward each other, and the two scraper strips 501 can be automatically lifted into the two inspection pipes 104.

[0091] Note: When removing the two scraper strips 501, it is necessary to rotate and adjust the two strip-shaped mounting rods 5 so that the two strip-shaped mounting rods 5 and the two inspection pipes 104 are located on the same horizontal line and aligned.
