Description

Technical Field

[0001] This utility model relates to the field of concrete foaming agent addition technology, specifically to a quantitative addition device for foamed concrete foaming agent. Background Technology

[0002] Foamed concrete is a lightweight, porous building material made from raw materials such as cement, lime, water, foaming agent, and admixtures. Its density is typically 300-1600 kg / m³. 3 Due to its excellent thermal insulation properties and good mechanical properties, foamed concrete is widely used in the construction industry. During the preparation of foamed concrete, the amount of foaming agent added has a significant impact on the product's density and performance. Precisely controlling the amount of foaming agent added is a key point in controlling the quality of foamed concrete.

[0003] Existing foaming agents are usually added manually, which cannot be precisely controlled in terms of quantity. This can easily lead to over- or under-addition. Their accuracy and reliability still need to be improved. Furthermore, due to poor metering accuracy, the prepared foamed concrete has poor homogeneity and unstable performance. In addition, most foaming agent storage tanks are inconvenient to clean after use, which makes it difficult to adjust the foaming agent formula according to the engineering performance requirements.

A positioning seat 11 is fixedly installed on the side, and a first electric telescopic rod 111 is fixedly installed on one side of the positioning seat 11. A discharge device 5 is fixedly installed in the middle of the top surface of the mounting frame 1. The discharge device 5 includes a discharge box 51. A through groove 52 is opened in the discharge box 51. A sealing door 53 is installed in the top surface of the discharge box 51. The output end of the first electric telescopic rod 111 is fixedly connected to one side of the sealing door 53. The sealing door 53 is slidably installed in the top surface of the discharge box 51 through the first electric telescopic rod 111. A discharge pipe 54 is fixedly installed on the bottom surface of the discharge box 51. The through groove 52, the discharge port 41 and the discharge pipe 54 are interconnected.

[0022] The foaming agent raw materials that need to be premixed are injected into the mixing tank 4 according to the ratio. The motor 31 is turned on and the stirring shaft 32 is rotated through the output end of the motor 31. When the stirring shaft 32 rotates, it drives the stirring paddle 34 installed by multiple mounting sleeves 33 to mix and stir the foaming agent raw materials in the mixing tank 4. When the foaming agent raw materials are mixed in the mixing tank 4 according to a certain ratio, the first electric telescopic rod 111 is turned on. With the cooperation of the first electric telescopic rod 111, the sealing door 53 is opened, so that the foaming agent that has been mixed in the mixing tank 4 is injected into the storage tank 6 through the discharge port 41, the through groove 52 and the discharge pipe 54 for storage and later use.

[0023] See Figure 3The mounting frame 1 of this application has a discharge pipe 13 fixedly mounted in the middle of its inner bottom surface. A control valve 131 is fixedly mounted on the surface of the discharge pipe 13. A storage tank 6 is installed in the middle of the mounting frame 1. The storage tank 6 includes a first tank body 61 and a second tank body 62. Fixing plates 12 are fixedly mounted on both sides of the mounting frame 1. There are two fixing plates 12. A second electric telescopic rod 121 is fixedly mounted in the middle of one side of each of the two fixing plates 12. There are two second electric telescopic rods 121. The output ends of the two second electric telescopic rods 121 are fixedly connected to one side surface of the first tank body 61 and the second tank body 62, respectively. The first tank body 61 and the second tank body 62 slide relative to each other in the mounting frame 1 through the second electric telescopic rods 121. The two ends of the first tank body 61 and the second tank body 62 are slidably mounted on the discharge pipe, respectively. The storage tank 6, along with the discharge pipe 54 and discharge pipe 13, cooperates with each other to store the pre-mixed foaming agent. When the foaming agent is needed, the control valve 131 is opened, and the foaming agent in the storage tank 6 is discharged into the concrete mixing tank through the discharge pipe 13. When the foaming agent needs to be cleaned in the storage tank 6, the switches of the two second electric telescopic rods 121 are opened. Under the operation of the two second electric telescopic rods 121, the first tank body 61 and the second tank body 62 of the storage tank 6 are opened to clean the inside, thereby increasing the cleaning effect inside the storage tank 6. With the cooperation of the discharge pipe 13 and the discharge pipe 54, the upper and lower ends of the storage tank 6 are sealed after closure, ensuring that the storage tank 6 can normally store the foaming agent.

[0024] See Figure 1 and Figure 4 In this application, the top surface of the positioning frame 3 is fixedly fitted with a hopper 7 on one side of the motor 31. The bottom surface of the hopper 7 is fixedly installed with a feeding platform 71. The feeding platform 71 cooperates with the mixing tank 4 to inject the foaming agent raw materials to be mixed into the hopper 7 in sequence. The foaming agent is pre-mixed in the mixing tank 4 through the feeding platform 71 installed on the bottom surface of the hopper 7.

[0025] See Figure 3 In this application, guide sleeves 63 are symmetrically installed on both sides of the first tank 61 and the second tank 62, and guide rods 14 are symmetrically installed on both sides inside the mounting frame 1. Two adjacent guide sleeves 63 of the first tank 61 and the second tank 62 slide relative to each other on the surface of a guide rod 14. The guide sleeves 63 and the guide rods 14 cooperate with each other. With the cooperation of the guide sleeves 63 and the corresponding guide rods 14 installed on both sides of the first tank 61 and the second tank 62, the first tank 61 and the second tank 62 are assisted in opening and closing, increasing the stability of the first tank 61 and the second tank 62 when moving, and at the same time completing the positioning of the first tank 61 and the second tank 62 in the mounting frame 1.

[0026] See Figure 3In this application, a connecting strip 621 is symmetrically installed on one side of the second tank 62, and a positioning groove 611 is symmetrically opened on one side of the first tank 61. There are two connecting strips 621 and two positioning grooves 611. The connecting strips 621 are slidably locked in the positioning grooves 611. With the cooperation of the two connecting strips 621 and the corresponding positioning grooves 611, the positioning when the first tank 61 and the second tank 62 are connected is increased, and the firmness of the first tank 61 and the second tank 62 after connection is increased.

[0027] See Figure 4 In this application, a rotating component 321 is sleeved on one end of the surface of the stirring shaft 32. The rotating component 321 is fixedly installed in the middle of the top surface of the positioning frame 3. The rotating component 321 cooperates with the stirring shaft 32. The rotating component 321 completes the installation and positioning of the stirring shaft 32 and assists the stirring shaft 32 to rotate, thereby increasing the stability of the stirring shaft 32 when it rotates.

[0028] See Figure 5 The mounting bracket 1 of this application has two support seats 8 fixedly installed on both sides of its bottom surface. Each of the two support seats 8 has a positioning strip 81 fixedly installed on one side. The positioning strip 81 has evenly distributed positioning holes 82. The device is supported and positioned by the two support seats 8. The positioning holes 82 in the two positioning strips 81 are used in conjunction with corresponding bolts to complete the installation and fixing of the device in the designated position.

[0029] Working principle: The foaming agent raw materials to be mixed are sequentially injected into the hopper 7, and then injected into the mixing tank 4 through the discharge platform 71 installed on the bottom of the hopper 7 for pre-mixing treatment of the foaming agent. After the pre-mixed foaming agent raw materials are injected into the mixing tank 4 according to the ratio, the switch of the motor 31 is turned on, and the output end of the motor 31 controls the stirring shaft 32 to rotate. When the stirring shaft 32 rotates, it drives the stirring paddle 34 installed by multiple mounting sleeves 33 to mix and stir the foaming agent raw materials in the mixing tank 4. After the foaming agent is mixed and stirred, the switch of the first electric telescopic rod 111 is turned on. With the cooperation of the first electric telescopic rod 111, the sealing door 53 is controlled to open, so that the foaming agent that has been mixed in the mixing tank 4 is injected into the storage tank 6 through the discharge port 41, the through groove 52 and the discharge pipe 54 for storage and later use.

[0030] When it is necessary to inject foaming agent into the concrete tank for mixing with concrete, open the control valve 131 to discharge the foaming agent stored in the storage tank 6 according to the ratio into the concrete mixing tank through the discharge pipe 13, and mix it with the concrete in the concrete tank. When it is necessary to clean the foaming agent storage tank 6, open the switches of the two second electric telescopic rods 121. Under the operation of the two second electric telescopic rods 121, control the opening of the first tank body 61 and the second tank body 62 of the storage tank 6, and clean its interior.
