Description

Technical Field

[0001] The utility model belongs to the technical field of adding devices, and particularly relates to a quick-setting agent adding device with uniform mixing. Background Technique

[0002] A quick-setting agent is a chemical additive added to concrete, which can significantly shorten its setting time, thereby accelerating the construction speed and improving the engineering efficiency.

[0003] Most of the existing quick-setting agent adding methods are manual adding or blowing in from the side of the mixing tank to mix the quick-setting agent with the raw materials.

[0004] The above-mentioned existing technology is likely to cause uneven mixing of the quick-setting agent and the concrete raw materials, resulting in too high a concentration of the quick-setting agent near the quick-setting agent discharge port, or too low a concentration of the quick-setting agent at one end of the mixing tank far from the quick-setting agent discharge port. The uneven mixing of the quick-setting agent in the concrete raw materials is likely to affect the strength and durability of the concrete raw materials, resulting in unstable performance and insufficient reliability of the final product. Content of the Utility Model

[0005] Aiming at the problems existing in the above-mentioned existing technology, the purpose of the utility model is to disclose a quick-setting agent adding device with uniform mixing to solve the problem of uneven mixing of the quick-setting agent and the concrete raw materials.

[0006] To solve the above problems, the utility model adopts the following technical solutions:

[0007] A quick-setting agent adding device with uniform mixing, comprising: a mixing cylinder, a mixing device, a control box, a quick-setting agent adding device, and a base.

[0008] Further, a mixing cylinder cover is installed on the mixing cylinder, a limiting hole is opened on the mixing cylinder cover, a feed hopper is arranged on the side of the mixing cylinder, a discharge port is opened at the bottom of the mixing cylinder, and the bottom of the mixing cylinder is installed on the base.

[0009] Further, the mixing device is arranged inside the mixing cylinder and includes a mixing shaft and spiral blades. The mixing shaft passes through the limiting hole on the mixing cylinder cover and is connected to the control box.

[0010] Further, the control box is arranged above the mixing cylinder and is installed on the base through a fixing rod on the base. A motor is installed inside the control box, and the power output end of the motor is connected to the power input end of the mixing shaft.

[0011] Further, the quick-setting agent adding device includes a quick-setting agent storage tank, a quick-setting agent feed pipe, and a quick-setting agent spray head. The quick-setting agent storage tank is installed inside the control box. An air inlet obliquely downward is opened on the upper side of the side of the quick-setting agent feed pipe to connect to an external high-pressure air source, and the lower end passes through the mixing cylinder cover and extends into the mixing cylinder. The quick-setting agent spray head is connected to the lower end of the quick-setting agent feed pipe.

[0012] Furthermore, a bayonet is provided at the upper end of the accelerator nozzle and is embedded in a bearing. The bearing is axially embedded in the accelerator feed pipe along the accelerator feed pipe, and a dust-proof sealing ring is installed on the bearing, enabling the accelerator nozzle to rotate. A discharge port is provided on the side of the bottom of the nozzle and extends downward tangentially.

[0013] Furthermore, the stirring device includes three stirring shafts, which are equidistantly installed on the spraying trajectory of the accelerator.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: The present utility model evenly disperses the accelerator on the concrete raw materials, and the accelerator is evenly stirred with the concrete raw materials through the stirring device, so that the accelerator is evenly dispersed inside the concrete raw materials.

Detailed Embodiment

[0019] In order to more clearly illustrate the technical solutions implemented by the present utility model, the present utility model will be described in detail below with reference to the drawings and embodiments.

[0020] Refer to Figures 1-3 , a uniformly mixed accelerator adding device, comprising: a mixing drum 1, a stirring device 2, a control box 3, an accelerator adding device 4, and a base 5.

[0021] Refer to Figures 1-3 , a mixing drum cover 11 is installed on the mixing drum 1, a limiting hole is provided on the mixing drum cover 11, a feed hopper 12 is provided on the side of the mixing drum 1, and a discharge port is provided at the bottom of the mixing drum 1. The bottom of the mixing drum 1 is installed on the base 5.

[0022] Refer to Figures 1-3, the stirring device 2 is arranged inside the mixing drum 1 and includes a stirring shaft 21 and spiral blades 22 installed on the stirring shaft. The stirring shaft 21 passes through the limiting hole on the mixing drum cover 11 and is connected to the control box 3.

[0023] Refer to Figures 1-3 , the control box 3 is arranged above the mixing drum 1 and is fixedly installed through the fixing rod 51 on the base. A motor 31 is installed inside the control box 3, and the power output end of the motor 31 is connected to the power input end of the stirring shaft 22.

[0024] Refer to Figures 1-3 , the accelerating admixture adding device 4 includes an accelerating admixture storage tank 41, an accelerating admixture feed pipe 42, and an accelerating admixture spray head 43. The accelerating admixture storage tank 41 is installed inside the control box 3. An air inlet 421 inclined downward is provided on the upper side of the accelerating admixture feed pipe 42, and the lower end passes through the mixing drum cover 11 and extends into the mixing drum 1. The accelerating admixture spray head 43 is connected to the lower end of the accelerating admixture feed pipe 42. During the feeding process of the accelerating admixture, a high-pressure gas source is connected, and the high-pressure gas blows the accelerating admixture into the accelerating admixture spray head along the accelerating admixture feed pipe 42.

[0025] Refer to Figures 1-3 , a bayonet at the upper end of the accelerating admixture spray head 43 is embedded in a bearing 44, and it is axially embedded in the accelerating admixture feed pipe 42 along the bearing 44. The bearing 44 is equipped with a dust-proof sealing ring, enabling the accelerating admixture spray head 42 to rotate. A discharge port 431 inclined downward in the tangential direction is provided on the side of the bottom of the spray head. When the high-pressure gas blows the accelerating admixture into the internal cavity of the accelerating admixture spray head 42, due to the discharge port 431 being inclined downward in the tangential direction, the high-pressure gas will drive the accelerating admixture spray head 42 to rotate along the bearing 44 and evenly spray the accelerating admixture downward onto the concrete raw materials.

[0026] Refer to Figures 1-3 , the stirring device 2 includes three stirring shafts 21, which are equidistantly installed on the accelerating admixture spraying trajectory and can participate in the stirring of most of the concrete raw materials in the mixing drum 1. During the stirring process, the spiral blades 22 can evenly mix the concrete raw materials with the accelerating admixture, generate a downward thrust, bring the accelerating admixture on the surface layer into the lower concrete raw materials, and assist the concrete raw materials to be discharged from the discharge port at the bottom of the mixing drum 1.

[0027] Refer to Figures 1-3 , the working process of the present utility model is as follows:

[0028] Put the concrete raw materials into the mixing drum 1 from the feed hopper 12, start the motor 31 in the control box 3 and put the accelerating agent into the accelerating agent storage tank 41. Connect the high-pressure gas to the air inlet 421 on the accelerating agent feed pipe 42. The high-pressure gas blows the accelerating agent into the accelerating agent spray head 43 below. The accelerating agent spray head 43 rotates in the direction of the bearing 44 under the gas pressure, sprays the accelerating agent evenly on the concrete raw materials below, and is evenly mixed by the mixing device 2. Since the concrete raw materials are continuously fed and are brought into the concrete raw materials by the spiral blade 22, the accelerating agent will not only stay on the surface of the concrete raw materials, realizing the uniform mixing of the accelerating agent and the concrete raw materials.
