Description

Technical Field

[0001] This utility model belongs to the field of concrete production technology, specifically relating to a concrete admixture processing and mixing device. Background Technology

[0002] During the addition of concrete admixtures, problems such as uneven dispersion, bleeding, abnormal setting time, and insufficient strength may occur. These problems are usually caused by inaccurate admixture dosage, uneven mixing, the influence of ambient temperature, or poor compatibility of the admixture. For admixtures with fixed particle sizes (retarders, accelerators, antifreeze agents, and expanding agents), which exist in different particle sizes, they are often added directly during the addition process. This results in localized areas where the admixture cannot be fully and evenly dispersed during concrete mixing. Combined with uneven mixing, this prevents the admixture from enhancing the quality of the concrete and reduces its effectiveness. Utility Model Content

[0003] The purpose of this invention is to provide a concrete admixture processing and mixing device that can solve the above-mentioned technical problems.

[0004] The specific technical solution adopted by this utility model is as follows:

[0005] This utility model provides a concrete admixture processing and mixing device, including a mixing cylinder and a mixing assembly disposed inside the mixing cylinder. A support base is installed on the lower side of the mixing cylinder, and a hopper frame is installed on the bottom surface of the mixing cylinder. The hopper frame is interconnected with the mixing cylinder. A slotting roller is rotatably installed inside the hopper frame. A feeding motor is installed on the upper surface of the mixing cylinder, and the output shaft of the feeding motor is installed on one side of the slotting roller. A blocking plate is correspondingly provided on the slotting roller to control the feeding amount of the hopper frame. The blocking plate is slidably installed on the lower side of the side plate of the hopper frame. An adjusting screw is provided on the top surface of the mixing cylinder, and one side of the adjusting screw is rotatably installed on the outer side of the blocking plate. A fixing plate is detachably installed on the bottom surface of the mixing cylinder. The adjusting screw is threadedly engaged with the fixing plate to adjust the gap between the blocking plate and the slotting roller, thereby controlling the feeding width.

[0006] The mixing assembly includes a central shaft, inner mixing plates, a rotating sleeve, and two sets of central stirring components. The central shaft is disposed inside the mixing cylinder and its upper side is mounted on the top plate of the mixing cylinder. The rotating sleeve is rotatably mounted on the bottom plate of the mixing cylinder. The lower side of the central shaft is rotatably mounted on the bottom plate of the mixing cylinder via the rotating sleeve. A forward and reverse drive mechanism is installed on the bottom surface of the mixing cylinder to drive the rotating sleeve and the central shaft to rotate in opposite directions.

[0007] The above-mentioned concrete admixture processing and mixing device starts one of the stabilizing shafts on the forward and reverse drive mechanism by a drive motor. At the same time, it drives the gears to rotate. The two meshing gears drive the two stabilizing shafts to rotate in opposite directions. One of the rotating stabilizing shafts drives the rotating sleeve to rotate through the reverse pulley set. The rotating sleeve drives the lower stabilizing plate and the two inner mixing plates to rotate, pushing and mixing the concrete material near the inner wall of the mixing cylinder. At the same time, the other stabilizing shaft rotates in the opposite direction and drives the central shaft to rotate through the drive pulley set. The central shaft drives the two central mixing components to rotate, impacting and mixing the concrete mixture in the mixing cylinder. In this way, in conjunction with the inner mixing plates rotating in opposite directions, the thorough mixing effect after adding admixtures in the mixing cylinder is improved.

[0008] When adding admixtures, first rotate the adjusting screw. With the support of the fixed plate, the adjusting screw drives the blocking plate to move, thereby adjusting the distance between the blocking plate and the slot roller to accommodate admixtures of different particle sizes. Then, the feeding motor drives the slot roller to rotate, and the material carrying the admixture is fed evenly, improving the uniformity of admixture addition. This, in conjunction with the mixing components, improves the mixing effect of admixture addition and enhances the quality of concrete.

[0009] Preferably, the two sets of central stirring components are arranged symmetrically in the mixing cylinder, the central stirring components are mounted on the central shaft, and four lifting mixing plates are arranged around the central stirring components, the lifting mixing plates being inclined at 45° to the horizontal direction.

[0010] Preferably, an upper stabilizing plate is provided above the central stirring component on the upper side of the mixing cylinder, and the upper stabilizing plate is rotatably mounted on the central shaft. A lower stabilizing plate is provided below the central stirring component on the lower side of the mixing cylinder, and the lower stabilizing plate is fixedly mounted on the upper side of the rotating sleeve. Two inner scrapers are provided on the inner wall of the mixing cylinder, and the inner scrapers are fixedly mounted on the same side of the upper stabilizing plate and the lower stabilizing plate.

[0011] Preferably, the inner mixing plate is fixedly installed on one side opposite to the upper and lower stabilizing plates, and the inner mixing plate is inclined at 5° to the vertical direction.

[0012] Preferably, the forward and reverse drive mechanism includes two stabilizing shafts, a drive pulley set, and a reverse pulley set. The two stabilizing shafts are rotatably mounted on the bottom surface of the mixing cylinder, and two meshing gears are mounted on the two stabilizing shafts. The drive pulley set is mounted on one of the stabilizing shafts and the central shaft, located on the lower side of the bottom surface of the mixing cylinder. The reverse pulley set is mounted on the other stabilizing shaft and the rotating sleeve, located on the lower side of the bottom surface of the mixing cylinder.

[0013] Preferably, a drive motor is mounted on the support base, and the output shaft of the drive motor is connected to the lower side of one of the stabilizing shafts.

[0014] Preferably, the length of the lifting mixing plate is three-quarters of the distance from the inner mixing plate to the central axis.

[0015] The beneficial effects are:

[0016] This invention utilizes a slotted roller, a feeding motor, a blocking plate, and an adjusting screw. The slotted roller, while rotating, evenly adds admixtures into the mixing drum. The adjusting screw allows for the movement and adjustment of the blocking plate, widening or narrowing the gap between the blocking plate and the slotted roller to accommodate admixtures of different sizes. Combined with the mixing assembly, this ensures thorough mixing of the materials within the mixing drum, thereby improving the mixing effect of the admixture after it has evenly dispersed within the drum. This enhances the overall mixing efficiency of the device after admixture addition and improves the quality of the concrete. Attached Figure Description

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figure 1-4As shown, a concrete admixture processing and mixing device includes a mixing cylinder 1 and a mixing assembly 2 disposed inside the mixing cylinder 1. A support base 3 is installed on the lower side of the mixing cylinder 1, and a hopper frame 4 is installed on the bottom surface of the mixing cylinder 1. The hopper frame 4 is interconnected with the mixing cylinder 1. A slotting roller 5 is rotatably installed inside the hopper frame 4. A feeding motor 6 is installed on the upper surface of the mixing cylinder 1. The output shaft of the feeding motor 6 is installed on one side of the slotting roller 5. A blocking plate 7 is correspondingly provided on the slotting roller 5 to control the feeding amount of the hopper frame 4. The blocking plate 7 is slidably installed on the lower side of the side plate of the hopper frame 4. An adjusting screw 8 is provided on the top surface of the mixing cylinder 1. One side of the adjusting screw 8 is rotatably installed on the outer side of the blocking plate 7. A fixing plate 9 is detachably installed on the bottom surface of the mixing cylinder 1. The adjusting screw 8 is threadedly engaged with the fixing plate 9 to adjust the gap between the blocking plate 7 and the slotting roller 5, thereby controlling the feeding width.

[0025] The mixing assembly 2 includes a central shaft 21, an inner mixing plate 26, a rotating sleeve 22, and two sets of central stirring components 210. The central shaft 21 is disposed inside the mixing cylinder 1 and is mounted on the top plate of the mixing cylinder 1. The rotating sleeve 22 is rotatably mounted on the bottom plate of the mixing cylinder 1. The lower side of the central shaft 21 is rotatably mounted on the bottom plate of the mixing cylinder 1 through the rotating sleeve 22. A forward and reverse drive mechanism is installed on the bottom surface of the mixing cylinder 1 to drive the rotating sleeve 22 and the central shaft 21 to rotate in opposite directions.

[0026] As an optional implementation, two sets of central stirring components 210 are arranged symmetrically in the mixing cylinder 1. The central stirring components 210 are mounted on the central shaft 21. Four lifting mixing plates 210a are arranged around the central stirring components 210. The lifting mixing plates 210a are inclined at 45° to the horizontal direction. This arrangement allows the lifting mixing plates 210a to use their inclination angle to impact the material in the mixing cylinder 1 towards the center when rotating, thereby improving the mixing effect.

[0027] An upper stabilizing plate 27 is provided above the central stirring component 210 on the upper side of the mixing cylinder 1. The upper stabilizing plate 27 is rotatably mounted on the central shaft 21. A lower stabilizing plate 28 is provided below the central stirring component 210 on the lower side of the mixing cylinder 1. The lower stabilizing plate 28 is fixedly mounted on the upper side of the rotating sleeve 22. Two inner scrapers 29 are provided on the inner wall of the mixing cylinder 1. The inner scrapers 29 are fixedly mounted on the same side of the upper stabilizing plate 27 and the lower stabilizing plate 28. This arrangement allows the inner scrapers 29 to scrape the inner wall of the mixing cylinder 1 under the action of the upper stabilizing plate 27 and the lower stabilizing plate 28, thereby preventing the material located on the inner wall of the mixing cylinder 1 from solidifying due to prolonged static time during mixing.

[0028] See attached document Figure 3 and attached Figure 4The inner mixing plate 26 is fixedly installed on the opposite side of the upper stabilizing plate 27 and the lower stabilizing plate 28. The inner mixing plate 26 is inclined at 5° to the vertical direction. This setting allows the inner mixing plate 26 to push the material in the mixing cylinder 1 up and down when it rotates, thereby cooperating with the central stirring component 210 to achieve comprehensive mixing of the material.

[0029] Furthermore, the forward and reverse drive mechanism includes two stabilizing shafts 23, a drive pulley set 21a, and a reverse pulley set 22a. The two stabilizing shafts 23 are rotatably mounted on the bottom surface of the mixing cylinder 1, and two meshing gears 24 are mounted on the two stabilizing shafts 23. The drive pulley set 21a is mounted on one of the stabilizing shafts 23 and the central shaft 21, located on the lower side of the bottom surface of the mixing cylinder 1. The reverse pulley set 22a is mounted on the other stabilizing shaft 23 and the rotating sleeve 22, located on the lower side of the bottom surface of the mixing cylinder 1. This arrangement allows the two stabilizing shafts 23 to rotate in opposite directions through the two meshing gears 24, thereby using the drive pulley set 21a and the reverse pulley set 22a to drive the central shaft 21 and the rotating sleeve 22 respectively.

[0030] Furthermore, a drive motor 25 is installed on the support base 3. The output shaft of the drive motor 25 is connected to the lower side of one of the stabilizing shafts 23. This arrangement allows the drive motor 25 to drive the central shaft 21 and the rotating sleeve 22 to rotate in opposite directions through the forward and reverse drive mechanism when it starts. A discharge pipe 10 that communicates with the interior is installed on the bottom surface of the mixing tank, and a control valve is installed on the discharge pipe 10.

[0031] Furthermore, the length of the lifting mixing plate 210a is three-quarters of the distance from the inner mixing plate 26 to the central axis 21. This setting ensures that the lifting mixing plate 210a will not come into contact with the inner mixing plate 26, which rotates in the opposite direction, thus guaranteeing the mixing effect of both.

[0032] Using the above structure, the drive motor 25 starts one of the stabilizing shafts 23 on the forward and reverse drive mechanism to rotate, and at the same time drives the gear 24 to rotate. The two meshing gears 24 drive the two stabilizing shafts 23 to rotate in opposite directions. One of the rotating stabilizing shafts 23 drives the rotating sleeve 22 to rotate through the reverse pulley group 22a, so that the rotating sleeve 22 drives the lower stabilizing plate 28 and the two inner side mixing plates 26 to rotate, pushing and mixing the concrete material near the inner wall of the mixing cylinder 1. At the same time, the other stabilizing shaft 23 rotates in the opposite direction and drives the central shaft 21 to rotate through the drive pulley group 21a, so that the central shaft 21 drives the two central mixing components 210 to rotate, impacting and mixing the concrete mixture in the mixing cylinder 1. In this way, in conjunction with the inner side mixing plates 26 rotating in opposite directions, the full mixing effect after the addition of admixtures in the mixing cylinder 1 is improved.

[0033] When adding admixtures, first rotate the adjusting screw 8. With the support of the fixed plate 9, the adjusting screw 8 drives the blocking plate 7 to move, thereby adjusting the distance between the blocking plate 7 and the slot roller 5 to accommodate admixtures of different particle sizes. Then, the feeding motor 6 drives the slot roller 5 to rotate and uniformly feed the material carrying the admixture, improving the uniformity of admixture addition. This, in conjunction with the mixing component 2, improves the mixing effect of admixture addition and enhances the quality of concrete.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
