Description

Technical Field

[0001] The utility model relates to the technical field of concrete anti-corrosion, in particular to a multi-admixture adding device suitable for producing high-performance anti-corrosion concrete. Background Art

[0002] To improve the anti-corrosion performance of concrete, some admixtures can be added, including mineral admixtures and preservatives. Mineral admixtures such as blast furnace slag and fly ash can improve the density and stability of concrete and prevent corrosive substances from further eroding the concrete surface. These admixtures can also reduce the increase in concrete temperature, which is conducive to maintaining the durability of concrete.

[0003] In addition, some preservatives can be added, such as nitrite, silane, etc. These preservatives can react with the substances in the concrete to form a dense protective layer and play an anti-corrosion role. You can also choose concrete materials with stable quality and good durability, such as high-strength concrete, corrosion-resistant concrete, etc.

[0004] In the process of making high-performance anti-corrosion concrete, since it involves the addition of multiple admixtures, it is a common setting method in the prior art to set a separate feeding device for each admixture. For example, a transmission belt for feeding is set for different types of concrete admixtures, and each transmission belt transports each different type of admixture to the mixer. This method is costly and complex in structure, and each transmission belt needs to be separately provided with a feeding hopper to meet the feeding needs of each transmission belt. In view of this, the present application provides a multi-admixture adding device suitable for the production of high-performance anti-corrosion concrete. Utility Model Content

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figures 1 to 7 As shown, the multi-admixture adding device suitable for the production of high-performance anticorrosive concrete provided by the utility model comprises a conveyor belt 1 and hoppers arranged on both sides of the conveyor belt 1. The hoppers are installed on a frame so as to be able to be raised and lowered in the height direction, and a winch 2 for lifting the hoppers is arranged on the frame. Side baffles 3 are arranged on both sides of the upper surface of the conveyor belt 1, and a docking hole 4 for docking the discharge end of the hopper is arranged on the side baffles 3. One hopper is arranged for each admixture, and multiple hoppers are distributed on both sides of the conveyor belt 1, and are arranged in sequence between the hoppers on the same side of the conveyor belt 1. The hopper is pulled up and down by the winch 2, which allows the addition of concrete admixtures on the ground, and then the winch 2 is used to lift it up to the highest position, and the hopper is docked with the docking hole 4, and then the admixtures in the hopper will gradually enter the conveyor belt 1. In this process, with the continuous operation of the conveyor belt 1, the various admixtures discharged from the hopper will be spread on the conveyor belt 1 and finally sent to the concrete mixer. The hoppers are distributed in sequence on the sides of the conveyor belt 1 , so that the concrete admixtures discharged from different hoppers are mixed together on the conveyor belt 1 , achieving a certain preliminary mixing effect.

[0030] The frame includes four longitudinal beams 5. The surface of the hopper is fixedly provided with a beam sleeve 6 which is slidably sleeved outside the longitudinal beam 5. The top ends of the four longitudinal beams 5 are connected by a cross beam, and the winch 2 is installed on the cross beam. During the lifting process of the hopper, the beam sleeve 6 guides the hopper. At the same time, the longitudinal beam 5 limits the maximum height of the hopper to prevent the hopper from hitting the side baffle 3. Specifically, the top end of the guide rod is provided with a portion whose size is larger than the inner diameter of the beam sleeve 6. When the hopper is lifted to the highest position, the top end of the beam sleeve 6 contacts the bottom end of the guide rod whose size is larger than the inner diameter of the beam sleeve 6.

[0031] The hopper includes a hopper body 7 and a discharge pipe 8 disposed at the bottom of the hopper body 7. The discharge pipe 8 is disposed in a state of being inclined toward one end of the conveyor belt 1, and the discharge end of the discharge pipe 8 is in a square structure as a whole. When the hopper rises to the highest position, the top of the discharge pipe 8 corresponding to the discharge end will contact the inner top wall of the docking hole 4. The concrete admixture in the hopper body 7 will automatically fall from the discharge pipe 8 under the action of its own gravity.

[0032] The side baffle 3 includes a first vertical portion 3-1 whose bottom end is supported on the top of the frame of the conveyor belt 1, an inclined portion 3-2 arranged on the first vertical portion 3-1 and with the top end inclined outward to the outside of the conveyor belt 1, and a second vertical portion 3-3 arranged on the top of the inclined portion 3-2. A docking hole 4 is opened on the second vertical portion 3-3, and the bottom end of the docking hole 4 penetrates the second vertical portion 3-3 to form a channel for the inner end of the discharge pipe 8 to enter.

[0033] By providing the inclined portion 3-2, the side baffle 3 has the function of preventing the concrete admixture from escaping from the conveyor belt 1 in the lateral direction of the conveyor belt 1, and the docking hole 4 is located outside the conveyor belt 1 in the width direction of the conveyor belt 1, so that the hopper can be docked with the docking hole 4. The admixture that slides out of the discharge pipe 8 will fall onto the inclined portion 3-2, and at this time, the inclined portion 3-2 guides the admixture onto the conveyor belt 1.

[0034] The discharge end of the discharge pipe 8 is provided with two oppositely arranged sealing plates 9, and the opposite sides of the top of the two sealing plates 9 are rotatably installed on the discharge pipe 8 through a mounting shaft, and a circular gear 10 is arranged on the mounting shaft. The inner surface of the second vertical part 3-3 is provided with a longitudinal rack 11, and the two side surfaces of the longitudinal rack 11 are respectively provided with teeth for meshing the two circular gears 10.

[0035] With such a configuration, when the discharge pipe 8 has not been docked with the docking hole 4, the two sealing plates 9 are in a closed state to prevent the concrete admixture from being discharged from the discharge end of the discharge pipe 8. When the discharge end of the discharge pipe 8 continues to move upward in the docking hole 4 until the top of the discharge pipe 8 contacts the inner top wall of the docking hole 4, the two circular gears 10 roll upward on the teeth on both sides of the longitudinal rack 11 respectively. At this time, the two sealing plates 9 are fully opened, so that the discharge port of the discharge pipe 8 is fully opened. When the hopper descends to the ground to add the slow-setting soil admixture, the longitudinal rack 11 cooperates with the circular gear 10 to restore the two sealing plates 9 to a closed state. At this time, the sealing plates 9 block the discharge port of the discharge pipe 8 again.

[0036] The inner side surface of the second vertical portion 3-3 is provided with a groove 12 for the sealing plate 9 to rotate, and the longitudinal rack 11 is fixed on the inner wall surface of the groove 12. Specifically, the sealing plate 9 covers the inner end of the discharge port of the discharge pipe 8. At this time, the sealing plate 9 is located within the range of the second vertical portion 3-3 in the width direction of the conveyor belt 1. Furthermore, the setting of the groove 12 provides space for the sealing plate 9 to rotate.

[0037] A connecting plate 13 is provided at the inner end of the bottom of the discharge pipe 8, and the top surface of the connecting plate 13 is an inclined surface parallel to the inclined portion 3-2, and when the upper surface of the discharge pipe 8 contacts the inner top wall of the docking hole 4, the top surface of the connecting plate 13 is flush with the inner side surface of the inclined portion 3-2. With such a configuration, after the sealing plate 9 is opened, there is a gap between the bottom of the discharge end of the discharge pipe 8 and the bottom of the docking hole 4, and then, the connecting plate 13 can block the gap to prevent concrete admixture from falling from the gap.

[0038] A transverse shaft 14 is installed between the two side baffles 3, and rake rods 15 are installed at equal intervals at the bottom of the transverse shaft 14. The end of the transverse shaft 14 extends to the outside of the side baffle 3 and is rotatably connected to an elastic support rod 16, and the end of the elastic support rod 16 away from the transverse shaft 14 is rotatably connected to the side baffle 3. Specifically, in the initial state, the elastic support rod 16 uses its elastic force to keep the rake rod 15 in a vertical downward state. When the concrete admixture carried on the conveyor belt 1 passes through the rake rod 15, the rake rod 15 can rake the concrete admixture, so that the concrete admixture can be more evenly distributed on the conveyor belt 1 for transportation, and at the same time, the mixing effect of various concrete admixtures is also improved.

[0039] Specifically, two or more groups of rake rods 15, transverse shafts 14 and elastic support rods 16 can be arranged in the length direction of the conveyor belt 1. At this time, two adjacent groups of rake rods 15 are staggered in the width direction of the conveyor belt 1 to improve the paving uniformity and mixing effect of the concrete admixture.

[0040] The bottom sliding sleeve of the beam sleeve 6 is provided with a buffer leg 17, which is sleeved on the longitudinal beam 5, and a buffer spring 18 is provided between the buffer leg 17 and the beam sleeve 6. The buffer leg 17 cooperates with the buffer spring 18, so that after the hopper is lowered to the lowest position, the buffer leg 17 is supported on the frame, which has a buffering effect on the hopper.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
