[0002] Reaction kettles are mainly containers used for physical or chemical reactions. Through the structural design and parameter configuration of the containers, functions such as heating, evaporation, cooling, and mixing at low and high speeds required by the process are achieved. Reaction kettles are widely used in fields such as petroleum, chemical industry, rubber, pesticides, dyes, medicine, and food.

[0003] After retrieval, a patent with the publication number CN105233779B discloses a horizontal reaction kettle, which includes the kettle body of the horizontal reaction kettle. A driving main shaft is horizontally arranged in the kettle body, one end of the driving main shaft is connected to a driving motor, and at least two spiral ribbon agitators are arranged on the main shaft in the kettle body.

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] A horizontal reaction kettle for processing chemical materials, as Figures 1 - 10 shown, includes a chassis 1, a reaction kettle body 2, an observation window 21, a discharge pipe 23, a feed pipe 22, a spiral scraping frame 65, a material pushing frame 7, a stirring mechanism, a heat dissipation mechanism and a driving mechanism. The chassis 1 is connected to the reaction kettle body 2 at the top. An observation window 21 is arranged on the right side of the top of the reaction kettle body 2 for observing the internal situation of the reaction kettle body 2. A plurality of feed pipes 22 for adding materials are evenly spaced and communicated on the left side of the reaction kettle body 2. A discharge pipe 23 is communicated at the right side of the inner bottom of the reaction kettle body 2. A valve is arranged at the discharge pipe 23. A stirring mechanism for stirring the materials is arranged on the reaction kettle body 2. The stirring mechanism includes a rotating shaft 41. The rotating shaft 41 is rotatably connected in the reaction kettle body 2. A heat dissipation mechanism is arranged in the reaction kettle body 2. The heat dissipation mechanism includes an inner cylinder 51. The inner cylinder 51 is arranged in the reaction kettle body 2. The spiral scraping frame 65 is rotatably connected to the rotating shaft 41. A driving mechanism for driving the spiral scraping frame 65 to rotate is arranged on the reaction kettle body 2. The spiral scraping frame 65 is closely attached to the inner wall of the inner cylinder 51 so that the spiral scraping frame 65 can convey the materials on the inner wall of the inner cylinder 51 to the right when rotating. Two symmetrically arranged material pushing frames 7 are arranged on the spiral scraping frame 65.

[0030] The stirring mechanism includes a stirring motor 3 and a stirring frame 42. The stirring motor 3 is installed in the middle of the left side of the reaction kettle body 2. The rotating shaft 41 is connected to the output shaft of the stirring motor 3. A plurality of stirring frames 42 are rotatably connected to the rotating shaft 41 at equal intervals. The stirring frames 42 are used for stirring the materials inside the reaction kettle body 2 to assist the materials inside the reaction kettle body 2 to react with each other.

[0031] The heat dissipation mechanism further includes a heat conduction pipe 52, a liquid inlet pipe 53 and a liquid outlet pipe 54. The outer circle of the inner cylinder 51 is wound with the heat conduction pipe 52. The heat conduction pipe 52 is spirally wound around the outer circle of the inner cylinder 51. The left end of the heat conduction pipe 52 is communicated with the liquid outlet pipe 54, and the liquid outlet pipe 54 penetrates through the reaction kettle body 2. The right end of the heat conduction pipe 52 is communicated with the liquid inlet pipe 53, and the liquid inlet pipe 53 penetrates through the reaction kettle body 2. The discharge pipe 23 extends into the inner cylinder 51.

[0032] The driving mechanism includes a reduction motor 61, a small gear 62, an internal gear ring 63 and a connecting ring 64. The left side of the spiral scraping rack 65 is connected with the connecting ring 64. The internal gear ring 63 is connected inside the connecting ring 64. The reduction motor 61 is installed at the lower left side of the reaction kettle body 2. The output shaft of the reduction motor 61 passes through the reaction kettle body 2 and is connected with the small gear 62 inside the inner cylinder 51. The small gear 62 meshes with the internal gear ring 63, so that the operation of the reduction motor 61 can drive the spiral scraping rack 65 to rotate through the small gear 62 and the internal gear ring 63.

[0033] When this horizontal reactor needs to be used, chemical materials can be first added into the reactor body 2 through the feed pipe 22. Different materials can be added respectively through multiple feed pipes 22. After the addition is completed, then control the stirring motor 3 to drive the rotating shaft 41 to rotate. When the rotating shaft 41 rotates, it drives the stirring frame 42 to rotate. When the stirring frame 42 rotates, it can stir the materials in the horizontal reactor to assist the reaction of the materials. During the reaction of the materials, if cooling is required, coolant can be added through the liquid inlet pipe 53 and the coolant can be extracted through the liquid outlet pipe 54, so that the coolant circulates along the heat conduction pipe 52, thereby cooling the materials. During the reaction process, due to the different qualities of the materials, the materials with larger density are likely to precipitate at the lower part inside the reactor body 2. At this time, the reduction motor 61 can be controlled to drive the small gear 62 to rotate forward and backward alternately. When the small gear 62 rotates, it can drive the internal gear ring 63 to rotate forward and backward alternately. The rotation of the internal gear ring 63 can drive the spiral scraping frame 65 to rotate. When the spiral scraping frame 65 rotates, it can push the materials attached to the inner wall of the inner cylinder 51 to the right to prevent materials from adhering to the inner wall of the inner cylinder 51. When the spiral scraping frame 65 rotates, it can also drive the material shifting frame 7 to rotate. When the material shifting frame 7 rotates, it can shift the materials at the lower part inside the inner cylinder 51 and shift the materials to the upper part inside the inner cylinder 51. At this time, the materials shifted by the material shifting frame 7 fall vertically downward without being blocked, and the materials can fall. At the same time, combined with the rotation of the stirring frame 42, the materials can be better mixed and reacted to avoid material deposition, so as to complete the reaction of the materials. After the reaction is completed, the valve at the discharge pipe 23 can be opened to discharge the materials through the discharge pipe 23. During the discharge, the reduction motor 61 is also controlled to drive the small gear 62 to continuously rotate in one direction, thereby driving the spiral scraping frame 65 to continuously rotate in one direction. At this time, the spiral scraping frame 65 rotates to scrape the materials attached to the inner wall of the inner cylinder 51 and convey the materials to the right for discharge to prevent materials from adhering to the inner wall of the inner cylinder 51. In this way, this horizontal reactor can be used, and during the use process, the materials deposited at the lower part of the inner cylinder 51 can be shifted upward to assist the mixing of the materials.

[0034] It further includes a transmission mechanism. The transmission mechanism includes a sliding rack frame 81 and a connecting gear 82. The sliding rack frame 81 is slidably connected to the rotating shaft 41. The middle part of the stirring frame 42 is connected with the connecting gear 82. The connecting gear 82 meshes with the sliding rack frame 81, so that the reciprocating sliding of the sliding rack frame 81 can drive the connecting gear 82 to rotate, thereby driving the stirring frame 42 to rotate to assist in stirring the materials inside the inner cylinder 51.

[0035] It also includes a guide wheel 83 and a convex shaft 832. In the middle of the right side wall inside the reaction kettle body 2, a guide wheel 83 is connected. The guide wheel 83 extends into the rotating shaft 41. A guide groove 831 is provided on the guide wheel 83. A convex shaft 832 is connected to the right side of the sliding rack 81. The convex shaft 832 is located in the guide groove 831, so that when the sliding rack 81 rotates, it can drive the convex shaft 832 to move along the guide groove 831, thereby driving the sliding rack 81 to reciprocate.

[0036] When the rotating shaft 41 rotates, it can drive the sliding rack 81 to rotate together. When the sliding rack 81 rotates, the convex shaft 832 on it will reciprocate along the guide groove 831 on the guide wheel 83, thereby driving the sliding rack 81 to reciprocate left and right. When the sliding rack 81 moves, it can drive the connecting gear 82 to rotate forward and backward alternately. When the connecting gear 82 rotates forward and backward alternately, it can drive the stirring frame 42 to rotate forward and backward alternately, so that while the rotating shaft 41 drives the stirring frame 42 to rotate, the stirring frame 42 itself can also rotate, improving the stirring effect.

[0037] It also includes an auxiliary mechanism. The auxiliary mechanism includes a liquid injection valve 91, a drain pipe 92 and a partition block 93. The partition blocks 93 are evenly spaced and installed on the front and rear sides of the upper part inside the reaction kettle body 2. The partition blocks 93 separate the local area in the upper part of the reaction kettle body 2 from other areas. The local area between the two partition blocks 93 is the cooling area. The liquid injection valves 91 are evenly spaced and installed on the upper part of the reaction kettle body 2 for injecting cooling liquid into the cooling area. The upper part of the heat conduction pipe 52 is located in the cooling area. The middle of the top of the reaction kettle body 2 is communicated with a drain pipe 92 for discharging the cooling liquid.

[0038] Initially, cooling liquid can be added to the cooling area through the drain pipe 92. When the cooling liquid in the heat conduction pipe 52 circulates, the heat dissipation of the materials inside the reaction kettle body 2 will cause the cooling liquid to accumulate heat. When the cooling liquid flows to the cooling area, the cooling liquid in the cooling area can cool the cooling liquid at the heat conduction pipe 52, achieving an auxiliary cooling effect.

[0039] It should be understood that this embodiment is only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of this application.
