Description

Technical Field

[0001] This utility model relates to the field of soil solidification admixture production technology, specifically a reaction vessel for the production of soil solidification admixtures. Background Technology

[0002] Liquid soil stabilizers have a complex composition, typically including the following categories of substances: Sodium silicate compounds, upon hydrolysis, produce silicate ions, which can react with metal ions in the soil to form a gel-like silicate gel. This gel fills the pores between soil particles, binding them together and improving soil strength and stability. Phosphate compounds react with calcium, magnesium, and other metal ions in the soil to form insoluble phosphate precipitates. These precipitates fill soil pores, strengthen the bond between soil particles, and improve soil strength and water stability. Organic polymers possess good adhesion and flexibility, forming a thin film on the surface of soil particles, encapsulating them, increasing friction and adhesion between particles, and improving soil shear and compressive strength. Surfactants can reduce the liquid content of the soil. Surface tension enhances the permeability and dispersibility of admixtures in soil, allowing them to better contact soil particles and promote various chemical reactions. Metal salts such as calcium chloride and ferric chloride may also be added to liquid soil stabilizers. These metal salts can react chemically with soil components to generate substances with gelling properties, thereby improving soil strength and stability. Water is an important component of liquid soil stabilizers. It not only serves as a medium for various chemical reactions but also adjusts the concentration and viscosity of the admixtures, ensuring better and more uniform mixing with the soil. Because liquid soil stabilizers contain diverse components, a reaction vessel is required during production. In the reaction vessel, multiple components are mixed together. However, liquid soil stabilizers are usually in a solid-liquid coexistence state, and ordinary reaction vessels are not very effective at mixing in this state. Utility Model Content

[0003] The purpose of this invention is to provide a reaction vessel for the production of soil solidification admixtures, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a reaction vessel for the production of soil stabilization admixtures, comprising a reaction vessel, a feeding pipe connected to the top of the reaction vessel, a discharge port at the bottom of the reaction vessel, a swing frame on the outer wall of the reaction vessel, a second geared motor fixedly installed on the top of the reaction vessel, a stirring shaft fixedly installed at the output end of the second geared motor, stirring blades fixedly installed on the outer wall of the stirring shaft, a reciprocating screw fixedly installed at the bottom end of the stirring shaft, an internally threaded tube threaded onto the outer wall of the reciprocating screw, a shaking basket fixedly installed on the outer wall of the internally threaded tube, the shaking basket fitting against the inner wall of the bottom of the reaction vessel, a limit strip fixedly installed on the inner wall of the reaction vessel, and a groove corresponding to the limit strip on the outer wall of the shaking basket.

[0005] Furthermore, the side of the shaking basket is provided with a through groove, and the bottom of the shaking basket is provided with a filter hole.

[0006] Furthermore, a sealing cap is snapped onto the top of the feeding pipe, and a discharge valve is provided at the bottom of the discharge port.

[0007] Furthermore, a heater is fixedly installed on the outer wall of the reactor, and the heating end of the heater extends into the reactor. There are two heaters, which are symmetrically distributed on the reactor.

[0008] Furthermore, an exhaust pipe is connected to the top of the reactor, and a pressure relief valve is connected to the top of the exhaust pipe.

[0009] Furthermore, the swing frame includes a support frame and a second rotating shaft. Two support frames and two rotating shafts are provided and located on the left and right sides of the reactor, respectively. The second rotating shaft is fixedly connected to the outer wall of the reactor. A first geared motor is fixedly installed on the support frame. The first rotating shaft is fixedly installed at the output end of the first geared motor. The first rotating shaft is connected to the second rotating shaft through a pulley set. The second rotating shaft is rotatably connected to the support frame through a bearing.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The reaction vessel is oscillated by a swing frame, which increases the degree of tumbling of the solid-liquid mixture inside the reaction vessel and improves the mixing degree of each component. The stirring shaft is driven to rotate by a geared motor, which in turn drives the reciprocating screw to rotate. Because the shaking basket is limited by the limit bar, the internal threaded tube can only move up and down when the reciprocating screw rotates, which in turn drives the shaking basket to move up and down. This is used to shake up the solid components that are easy to settle at the bottom of the reaction vessel, so that the solid components can also fully participate in the mixing process and ensure the mixing effect.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1-6This utility model provides a technical solution: a reaction vessel for the production of soil stabilization admixtures, comprising a reaction vessel 1, a feed pipe 2 connected to the top of the reaction vessel 1, a discharge port 3 at the bottom of the reaction vessel 1, a swing frame 4 on the outer wall of the reaction vessel 1, a reduction motor 8 fixedly installed on the top of the reaction vessel 1, a stirring shaft 9 fixedly installed at the output end of the reduction motor 8, stirring blades 10 fixedly installed on the outer wall of the stirring shaft 9, a reciprocating screw 11 fixedly installed at the bottom end of the stirring shaft 9, an internally threaded tube 13 threaded onto the outer wall of the reciprocating screw 11, a shaking basket 12 fixedly installed on the outer wall of the internally threaded tube 13, the shaking basket 12 fitting against the inner wall of the bottom of the reaction vessel 1, and a fixed arrangement on the inner wall of the reaction vessel 1. The outer wall of the shaking basket 12 is provided with a groove corresponding to the limiting bar 14. The reaction vessel 1 is swung by the swing frame 4, thereby increasing the degree of tumbling of the solid-liquid mixture in the reaction vessel 1 and improving the mixing degree of each component. The stirring shaft 9 is driven to rotate by the reduction motor 8, which in turn drives the stirring blade 10 and the reciprocating screw 11 to rotate. The stirring blade 10 rotates to stir the solid-liquid mixture. Because the shaking basket 12 is limited by the limiting bar 14, the internal threaded tube 13 can only move up and down when the reciprocating screw 11 rotates, thereby driving the shaking basket 12 to move up and down to shake up the solid components that are easy to settle at the bottom of the reaction vessel 1, so that the solid components can also fully participate in the mixing process and ensure the mixing effect.

[0021] The side of the shaking basket 12 is provided with a through groove 1201 and the bottom of the shaking basket 12 is provided with a filter hole 1202. The filter hole 1202 is provided to filter the agglomerated solid components. The through groove 1201 on the side of the shaking basket 12 is used to leave enough space for liquid to flow, reduce the resistance encountered by the shaking basket 12 during the up and down reciprocating movement, and because the through groove 1201 is located on the side of the shaking basket 12, it can also prevent the solid components that sink to the bottom from leaking out of the shaking basket 12.

[0022] The top of the feed pipe 2 is fitted with a sealing cap 5, and the bottom of the discharge port 3 is equipped with a discharge valve 6. The sealing cap 5 and the discharge valve 6 are provided to prevent the mixture in the reactor 1 from splashing and leaking out during the process of the reactor 1 being swung by the swing frame 4.

[0023] A heater 7 is fixedly installed on the outer wall of the reactor 1. The heating end of the heater 7 extends into the reactor 1. There are two heaters 7, which are symmetrically distributed on the reactor 1 to heat the solid-liquid mixture in the reactor 1, so that the solid-liquid mixture can react at a better temperature.

[0024] An exhaust pipe 15 is connected to the top of the reactor 1, and a pressure relief valve 16 is connected to the top of the exhaust pipe 15. During the mixing and reaction of various components in the reactor 1, some gas will be generated. The exhaust pipe 15 and the pressure relief valve 16 are provided to maintain the gas pressure balance in the reactor 1.

[0025] The swing frame 4 includes a support frame 401 and a second rotating shaft 404. There are two support frames 401 and two rotating shafts 404, which are located on the left and right sides of the reactor 1, respectively. The second rotating shaft 404 is fixedly connected to the outer wall of the reactor 1. A first geared motor 402 is fixedly installed on the support frame 401. A first rotating shaft 403 is fixedly installed at the output end of the first geared motor 402. The first rotating shaft 403 is connected to the second rotating shaft 404 through a pulley set. The second rotating shaft 404 is rotatably connected to the support frame 401 through a bearing. The first geared motor 402 drives the first rotating shaft 403 to reciprocate in both forward and reverse directions, thereby causing the second rotating shaft 404 to drive the reactor 1 to swing.

[0026] Working principle: During use, pour each component into the reactor 1 through the feed pipe 2, then close the sealing cover 5, turn on the geared motor 402 to drive the rotating shaft 403 to reciprocate in both forward and reverse directions, which in turn causes the rotating shaft 404 to swing the reactor 1. At the same time, turn on the geared motor 8 and the heater 7. The geared motor 8 drives the stirring shaft 9 to rotate, which in turn drives the stirring blades 10 and the reciprocating screw 11 to rotate. The stirring blades 10 rotate to stir the solid-liquid mixture. When the reciprocating screw 11 rotates, the internal threaded tube 13 moves up and down, which in turn drives the shaking basket 12 to move up and down, which is used to shake up the solid components that are easy to settle at the bottom of the reactor 1, so that the solid components can also fully participate in the mixing process and ensure the mixing effect. The heater 7 heats the solid-liquid mixture in the reactor 1, so that the solid-liquid mixture can react at an optimal temperature.

[0027] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
