Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a reaction device for producing concrete admixtures. Background Technology

[0002] As a key material for improving concrete performance, concrete admixtures place high demands on the mixing efficiency, ease of cleaning, and product quality stability of the production process. However, traditional concrete admixture reaction devices suffer from the following problems in practical applications:

[0003] First, existing reaction devices mostly use paddle or anchor stirrers, whose mixing effect is mainly concentrated in the area near the stirring shaft. For high-viscosity materials or solid-liquid mixtures, this can easily create dead zones in the stirring, leading to uneven local concentrations, which affects the reaction rate and product performance consistency. Furthermore, the material near the tank wall has poor flowability and is prone to forming temperature gradients, further exacerbating the uneven reaction phenomenon.

[0004] Secondly, during the production of additives, some materials tend to adhere to the inner wall of the reaction vessel, forming a scale layer. This scale not only affects the heat transfer efficiency, causing local overheating and side reactions, but also falls off and mixes into the product, affecting its quality. Utility Model Content

[0005] This utility model relates to a reaction device for the production of concrete admixtures, which solves the problems of existing reaction tanks easily forming dead zones for stirring, resulting in uneven local concentrations, affecting the reaction rate and product performance consistency, and some materials easily adhering to the inner wall of the reaction tank to form a scale layer, which affects the heat transfer efficiency.

[0006] This utility model provides a reaction device for producing concrete admixtures, specifically including: a reaction tank;

[0007] The upper part of the reaction vessel is divided into a barrel-shaped structure, and the lower part of the reaction vessel is divided into a conical structure. A discharge pipe is fixedly installed at the lower end of the reaction vessel, and three support legs are installed in a ring on the lower end face of the reaction vessel.

[0008] The cover plate is located at the upper part of the reaction vessel. The cover plate has a circular plate structure and six second connection holes are provided on the surface of the cover plate. The six second connection holes are arranged in a ring structure.

[0009] A drive motor is fixedly installed at the middle position of the upper end face of the cover plate, and a drive shaft is connected to the lower end face of the drive motor.

[0010] The scraper has a spiral structure and is located inside the reaction vessel. A connecting rod is fixedly installed on the inner end face of the scraper, and the other end of the connecting rod is fixedly connected to the drive shaft.

[0011] Furthermore, the outer end face of the scraper is in contact with the inner end face of the reaction vessel, and two mixing teeth are symmetrically installed on the outer end face of the connecting rod, with the mixing teeth having an inclined structure.

[0012] Furthermore, two handles are fixedly installed on the upper surface of the cover plate, and the handle body has an inverted U-shaped structure.

[0013] Furthermore, the upper end face of the reaction vessel is provided with six first connection holes, the inside of which is threaded. The six first connection holes are arranged in a ring structure, and the bolt passes through the second connection hole and is threaded into the first connection hole.

[0014] Furthermore, an observation window is provided on the side wall surface of the reaction vessel, and an observation glass is installed on the inner wall of the observation window.

[0015] Furthermore, two inclined feed pipes are symmetrically installed on the outer end face of the reaction vessel, and a control valve is installed inside the discharge pipe at the lower end of the reaction vessel.

[0016] This utility model provides a reaction device for producing concrete admixtures, which has the following beneficial effects:

[0017] 1. The drive motor can drive the drive shaft to rotate, which in turn drives the spiral scraper to rotate synchronously. Since the outer end face of the scraper is in contact with the inner wall of the reaction tank, it can scrape off the material adhering to the tank wall when rotating, preventing scaling. The inclined mixing teeth on the connecting rod rotate with the scraper, forming a secondary stirring in the radial direction. Together with the axial pushing action of the spiral scraper, they form a three-dimensional mixing flow field, which significantly improves the mixing uniformity. The conical bottom design of the reaction tank allows the material to flow towards the discharge pipe under the action of gravity and scraper thrust, forming a circulation path and further enhancing the mixing effect.

[0018] 2. The side wall of the reaction vessel is equipped with an observation window, through which operators can monitor the reaction progress and material status in real time. The observation glass is made of acid and alkali resistant materials to ensure transparency for long-term use. After the reaction is completed, the control valve of the discharge pipe is opened. Due to the guiding effect of the conical bottom, the material is quickly discharged under the combined action of gravity and scraper thrust, reducing residue. The continuous rotation of the spiral scraper can prevent high-viscosity materials from clogging the discharge port, which is especially suitable for the production of gelling additives.

[0019] 3. The cover plate is connected to the reaction vessel by bolts. When cleaning the reaction vessel, the bolts can be removed and the cover plate can be quickly disassembled by the handle, which facilitates cleaning or maintenance of the inside of the reaction vessel and the scraper. The spiral scraper's structural design makes it difficult for materials to remain on its surface, further reducing the difficulty of cleaning. Attached Figure Description

[0034] The upper part of the reaction vessel 1 is divided into a barrel-shaped structure, and the lower part of the reaction vessel 1 is divided into a conical structure. A discharge pipe 102 is fixedly installed at the lower end of the reaction vessel 1. Three support legs 101 are installed in a ring on the lower end face of the reaction vessel 1. The three support legs 101 can improve the stability of the reaction vessel 1.

[0035] Cover plate 2 is located at the upper part of reaction vessel 1. Cover plate 2 has a circular plate structure and six second connection holes 201 are provided on the surface of cover plate 2. The six second connection holes 201 are arranged in a ring structure.

[0036] The drive motor 3 is fixedly installed at the middle position of the upper end face of the cover plate 2, and the lower end face of the drive motor 3 is connected to the drive shaft 301.

[0037] The scraper 4 has a spiral structure and is located inside the reaction vessel 1. A connecting rod 401 is fixedly installed on the inner end face of the scraper 4, and the other end of the connecting rod 401 is fixedly connected to the drive shaft 301.

[0038] The outer end face of the scraper 4 is in contact with the inner end face of the reaction vessel 1. Two mixing teeth 4011 are symmetrically installed on the outer end face of the connecting rod 401. The mixing teeth 4011 have an inclined structure. During use, since the outer end face of the scraper 4 is in contact with the inner wall of the reaction vessel 1, the material adhering to the vessel wall can be scraped off when it rotates, preventing scaling. The inclined mixing teeth 4011 on the connecting rod 401 rotate with the scraper 4, forming a secondary stirring in the radial direction. Together with the axial pushing action of the spiral scraper 4, they form a three-dimensional mixing flow field, which significantly improves the mixing uniformity.

[0039] Two handles 202 are fixedly installed on the upper surface of the cover plate 2. The main body of the handle 202 is an inverted U-shaped structure. The handles 202 facilitate the disassembly of the cover plate 2 by workers.

[0040] The upper end face of the reaction vessel 1 is provided with six first connection holes 105. The inside of the first connection holes 105 is provided with threads. The six first connection holes 105 are arranged in a ring structure. The bolt passes through the second connection hole 201 and is threaded into the first connection hole 105. When cleaning the reaction vessel 1, the bolt can be removed to clean the reaction vessel 1.

[0041] The side wall surface of the reaction vessel 1 is provided with an observation window 103, and the inner wall of the observation window 103 is equipped with observation glass, so that workers can observe the reaction inside the reaction vessel 1.

[0042] The outer end face of the reaction vessel 1 is symmetrically equipped with two inclined feed pipes 104. The discharge pipe 102 at the lower end of the reaction vessel 1 is equipped with a control valve 1021. During use, the operator injects liquid or powdered raw materials into the reaction vessel 1 through the inclined feed pipes 104. The inclined design causes the material to flow in along the tangential direction of the inner wall of the vessel, and uses inertia to form a preliminary swirling flow, providing the basic conditions for subsequent mixing.

[0043] The working principle of this embodiment is as follows: The operator injects liquid or powdered raw materials into the reaction tank 1 through the inclined feed pipe 104. The inclined design causes the material to flow tangentially along the inner wall of the tank, forming an initial swirling flow using inertia, providing the basic conditions for subsequent mixing. After the drive motor 3 starts, it drives the drive shaft 301 to rotate, which in turn drives the spiral scraper 4 to rotate synchronously. Since the outer end face of the scraper 4 is in contact with the inner wall of the reaction tank 1, it can scrape off the material adhering to the tank wall when rotating, preventing scaling. The inclined mixing teeth 4011 on the connecting rod 401 rotate with the scraper 4, forming secondary stirring in the radial direction. Together with the axial pushing action of the spiral scraper 4, they form a three-dimensional mixing flow field, significantly improving the mixing uniformity. The conical bottom design of the reaction tank 1 causes the material to flow towards the discharge pipe 102 under the action of gravity and the thrust of the scraper 4, forming a circulation path, further enhancing the mixing effect. An observation window 103 is provided on the side wall surface of the reaction vessel 1. Operators can monitor the reaction progress and material status in real time through the observation window 103. The observation glass is made of acid and alkali resistant material to ensure transparency for long-term use. After the reaction is completed, the control valve 1021 of the discharge pipe 102 is opened. Due to the guiding effect of the conical bottom, the material is quickly discharged under the dual action of gravity and the thrust of the scraper 4, reducing residue. The continuous rotation of the spiral scraper 4 can prevent high-viscosity materials from clogging the discharge port, which is especially suitable for the production of gelling additives. The cover plate 2 is connected to the reaction vessel 1 by bolts. When cleaning the reaction vessel 1, the bolts can be removed, and the cover plate 2 can be quickly disassembled by the handle 202, which is convenient for cleaning or maintenance of the inside of the reaction vessel 1 and the scraper 4. The structural design of the spiral scraper 4 makes it difficult for material to remain on its surface, further reducing the difficulty of cleaning.
