Description

Technical Field

[0001] This utility model relates to the field of raw material premixing tank technology, specifically, to a raw material premixing tank used in the production of cement admixtures. Background Technology

[0002] Cement admixtures are functional chemical substances that can be added during the mixing process of cement-based materials such as concrete and mortar to significantly improve their workability, mechanical properties, or durability. They are one of the core materials for achieving "high performance, low energy consumption, and green" in modern concrete engineering. The production of cement admixtures usually requires mixing 2-6 different forms and concentrations of raw materials in precise proportions. The core function of the premix tank is to solve the problems of easy stratification and easy deviation in proportion when directly mixing.

[0003] Because some of the raw materials for cement admixtures are corrosive liquids, when adding the raw materials into the premixing pipe, the conveying pipe is usually connected to the top of the metering pump and the premixing tank, so that multiple raw materials are added into the premixing tank in sequence. After the material is conveyed, the conveying pipe is usually flushed inside to facilitate the continued conveying of subsequent raw materials.

[0004] During cleaning, workers need to disassemble and separate the delivery pipeline from the premix tank, then connect the high-pressure pump to the delivery pipeline to introduce water into the pipeline for flushing and cleaning, which is quite troublesome. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this utility model provide a raw material premix tank for cement admixture production, which solves the technical problem in the prior art that when cleaning the conveying pipeline, it is necessary to disassemble it and connect it to a high-pressure pump for water supply and cleaning, which is quite troublesome.

[0006] According to one aspect, at least one embodiment of the present invention provides a raw material premixing tank for cement admixture production, comprising two support frames and a premixing tank body, the premixing tank body being fixedly installed between the two support frames, and further comprising a water receiving cylinder, a vertical sliding assembly, a horizontal sliding assembly, a conveying pipe, a support fixing assembly, and a telescopic pipe. The water receiving cylinder is fixedly installed between the two support frames.

[0007] Furthermore, the vertical sliding assembly includes a first slide rail, a first slide rod, and a first fixing ring. The first slide rail is fixedly installed on the top of the support frame, the first slide rod is slidably installed on the first slide rail, and the first fixing ring is fixedly installed on the top of the first slide rail.

[0008] Furthermore, the transverse sliding assembly includes a second slide rail, a second slide rod, and a second fixing ring. The second slide rail is fixedly installed on the side of the support frame. There are two second slide rods, one of which is slidably installed on the side of the second slide rail, and the other is fixedly installed on the side of the first slide rod. There are two second fixing rings, which are respectively fixedly installed on the sides of the two second slide rods. The material conveying pipe is fixedly installed on the first fixing ring and the two second fixing rings.

[0009] Furthermore, the support and fixing assembly includes a base frame, a through rod, a first fixing plate, a second fixing plate, and fixing bolts. The base frame is fixedly installed on the side of the support frame. The bottom end of the through rod is slidably installed on the top end of the base frame and fixedly installed on two second sliding rods. Two first fixing plates are provided, and the two first fixing plates are respectively fixedly installed on both sides of the base frame. Two second fixing plates are provided, and the two second fixing plates are respectively fixedly installed on both sides of the base frame. Threaded holes are provided on the sides of the first fixing plate, the second fixing plate, and the through rod, and the fixing bolts are threaded into the threaded holes.

[0010] Furthermore, the lifting assembly includes a connecting plate, hooks, hook frames, and winding rods. The connecting plate is fixedly installed on the material conveying pipe. Two hooks are provided, and the two hooks are fixedly installed on the bottom end of the connecting plate by connecting ropes. Hook frames are fixedly installed on both sides of the telescopic tube, and winding rods are fixedly installed on both sides of the material conveying pipe.

[0011] Furthermore, a connecting hole is provided at the top of the premix tank body. When the first fixing plate corresponds to the threaded hole of the through rod, the telescopic tube and the connecting hole are located in the same vertical position.

[0012] Furthermore, when the second fixing plate corresponds to the threaded hole of the through rod, the telescopic tube is located directly above the water receiving cylinder.

[0013] Furthermore, valves are connected to the bottom ends of both the water receiving cylinder and the premix tank body, and flanges are connected to the telescopic pipe.

[0014] The beneficial effects of this utility model are as follows: In this invention, when cleaning the conveying pipeline, the operator first lifts the telescopic pipe out of the premixing tank body using the lifting component.

[0024] like Figures 1-5As shown, this invention illustrates a raw material premixing tank for cement admixture production according to one embodiment of the present invention. The tank includes two support frames 1 and a premixing tank body 2, with the body 2 fixedly installed between the two support frames 1. It also includes a water receiving cylinder 3, a vertical sliding assembly, a horizontal sliding assembly, a material conveying pipe 4, a support fixing assembly, and a telescopic pipe 5. The water receiving cylinder 3 is fixedly installed between the two support frames 1. The vertical sliding assembly is located at the top of the support frame 1, and the horizontal sliding assembly is located on the side of the support frame 1. The material conveying pipe 4 is located on the horizontal and vertical sliding assemblies. The horizontal and vertical sliding assemblies are used to move the material conveying pipe 4 above the water receiving cylinder 3 during cleaning. The support fixing assembly is located on the side of the support frame 1 to provide vertical support for the material conveying pipe 4. The telescopic pipe 5 is slidably installed through the outlet of the material conveying pipe 4 via a lifting assembly.

[0025] like Figure 2 As shown, when mixing cement admixtures, the worker first moves the conveying pipe 4 above the premix tank body 2 using a vertical sliding assembly and a horizontal sliding assembly. The vertical sliding assembly includes a first slide rail 6, a first slide rod 7, and a first fixing ring 8. The first slide rail 6 is fixedly installed on the top of the support frame 1, the first slide rod 7 is slidably installed on the first slide rail 6, and the first fixing ring 8 is fixedly installed on the top of the first slide rail 6. The horizontal sliding assembly includes a second slide rail 9, a second slide rod 10, and a second fixing ring 11. The second slide rail 9 is fixedly installed on the side of the support frame 1. There are two second slide rods 10, one of which is slidably installed on the side of the second slide rail 9, and the other is fixedly installed on the side of the first slide rod 7. There are two second fixing rings 11, which are respectively fixedly installed on the sides of the two second slide rods 10. The conveying pipe 4 is fixedly installed on the first fixing ring 8 and the two second fixing rings 11.

[0026] Specifically, the worker holds the second slide bar 10, which drives the two second fixing rings 11 to move on the second slide rail 9. At the same time, when one of the second slide bars 10 is connected to the side of the first slide bar 7, it can simultaneously drive the first slide bar 7 to drive the first fixing ring 8 to move synchronously on the first slide rail 6. It should be added that the material conveying pipe 4 is set in a Z-shape, and the first fixing ring 8 and the second fixing ring 11 are fixed at different positions on the material conveying pipe 4, so that its movement can be more stable.

[0027] like Figure 3As shown, during movement, the bottom end of the conveying pipe 4 can be supported by the supporting and fixing components, and the position of the conveying pipe 4 can be positioned. The supporting and fixing components include a base frame 12, a through rod 13, a first fixing plate 14, a second fixing plate 15, and fixing bolts 16. The base frame 12 is fixedly installed on the side of the support frame 1. The bottom end of the through rod 13 is slidably installed on the top end of the base frame 12, and the through rod 13 is fixedly installed on two second sliding rods 10. There are two first fixing plates 14, which are respectively fixedly installed on both sides of the base frame 12. There are two second fixing plates 15, which are respectively fixedly installed on both sides of the base frame 12. Threaded holes are opened on the sides of the first fixing plate 14, the second fixing plate 15, and the through rod 13, and the fixing bolts 16 are threaded into the threaded holes.

[0028] Specifically, when the second slide rod 10 moves horizontally, it can simultaneously drive the through rod 13 to slide on the base frame 12. Because the top of the premix tank body 2 has a connecting hole, when the threaded hole of the first fixing plate 14 corresponds to the threaded hole of the through rod 13, the telescopic tube 5 and the connecting hole are located in the same vertical position. Move the threaded hole of the through rod 13 to the position corresponding to the threaded hole of the first fixing plate 14, and then thread the fixing bolt 16 into it to fix it. In addition, it should be added that a tripod is fixedly installed on both sides of the first slide rod 7 and the through rod 13, and the tripod is slidably installed on the first slide rail 6 and the base frame 12, thereby stabilizing the bottom of the first slide rod 7 and the through rod 13.

[0029] like Figure 4 As shown, after the movement is complete, the telescopic tube 5 is inserted into the connecting hole at the top of the premix tank body 2 via the lifting assembly. The lifting assembly includes a connecting plate 17, hooks 18, hook brackets 19, and a winding rod 20. The connecting plate 17 is fixedly installed on the conveying pipe 4. Two hooks 18 are provided, and the two hooks 18 are fixedly installed at the bottom end of the connecting plate 17 by connecting rope 23. Hook brackets 19 are fixedly installed on both sides of the telescopic tube 5, and winding rods 20 are fixedly installed on both sides of the conveying pipe 4. Specifically, at this time, the telescopic tube 5 is located above the connecting hole and is not inserted into it. Furthermore, hook 18 is hooked to hook frame 19, so that telescopic pipe 5 is located on conveying pipe 4. At this time, the connecting rope 23 is partially wrapped around winding rod 20. After the movement is completed, the worker touches the ladder and moves up, then releases hook 18, and then the connecting rope 23 is released from winding rod 20. At this time, the length of connecting rope 23 increases, and then the telescopic pipe 5 slides into the connecting hole. Because flange 22 is installed on the telescopic pipe 5, the worker then fixes the telescopic pipe 5 through flange 22 to the top of premix tank body 2. Then the worker comes down and proceeds with subsequent material conveying.

[0030] After mixing is complete, the flange 22 is removed from the top of the premix tank body 2, and then the telescopic pipe 5 is slid up. Then the hook 18 is hung on the hook frame 19. Since the telescopic pipe 5 is located directly above the water receiving cylinder 3 when the threaded hole of the second fixing plate 15 corresponds to the threaded hole of the through rod 13, the conveying pipe 4 is moved until the threaded hole of the second fixing plate 15 corresponds to the threaded hole of the through rod 13. The fixing bolt 16 is then threaded into the threaded hole for fixing. Then, the inlet end of the conveying pipe 4 is connected to the high-pressure pump, and the high-pressure pump is connected to the water source. After the water source passes through the inside of the conveying pipe 4, it flushes the inside. After flushing, the water source falls directly into the receiving cylinder. The bottom ends of the water receiving cylinder 3 and the premix tank body 2 are both connected to valves 21, which can discharge the mixed material and the washing water.

[0031] Working principle: When mixing cement admixtures, the worker first holds the second slide rod 10. At this time, the second slide rod 10 drives the two second fixing rings 11 to move on the second slide rail 9. While one of the second slide rods 10 is connected to the side of the first slide rod 7, it can simultaneously drive the first slide rod 7 to drive the first fixing ring 8 to move on the first slide rail 6, thereby moving the conveying pipe 4. When the second slide rod 10 moves horizontally, it can simultaneously drive the through rod 13 to slide on the base frame 12, moving the threaded hole of the through rod 13 to the position corresponding to the threaded hole of the first fixing plate 14. Then, the fixing bolt 16 is threaded in and fixed. After fixing, the worker moves up the ladder and then releases the hook 18, and then the connecting rope 23 is released from the winding rod 20. At this time, the length of the connecting rope 23 increases, and then the telescopic pipe 5 slides into the connecting hole. Because the telescopic pipe 5 is connected to the flange 22, the worker fixes the telescopic pipe 5 through the flange 22 to the top of the premix tank body 2. Then the worker gets down and proceeds with the subsequent material conveying.

[0032] like Figure 5 As shown, during material conveying, a metering pump connects to one end of the conveying pipeline 4, thereby sequentially conveying various raw materials to the premixing tank body 2 through the conveying pipeline. It should be noted that the various raw materials can be mixed, so they can be conveyed through the same conveying pipeline. Furthermore, both the premixing tank body 2 and the conveying pipeline are made of corrosion-resistant materials, and the metering pump can convey a specified quantity or mass of material. At the same time, the internal components of the metering pump can be made of corrosion-resistant materials to avoid damage to the device when conveying corrosive raw materials. After the material conveying is completed, the material is stirred and mixed by the stirring device inside the premixing tank body 2. After the mixing is completed, the operator, wearing protective clothing, opens the valve 21 at the bottom of the premixing tank body 2, connecting the pump body to convey the material inside.

[0033] After mixing, the workers remove flange 22 from the top of the premix tank body 2, then slide the telescopic pipe 5 up, and then hang the hook 18 on the hook frame 19. Then, they move the conveying pipe 4 until the threaded hole of the second fixing plate 15 corresponds to the threaded hole of the through rod 13, and then fix the fixing bolt 16 in the threaded hole again. Then, they connect one end of the water inlet of the conveying pipe 4 to the high-pressure pump, and the high-pressure pump is connected to the water source. After the water source passes through the inside of the conveying pipe 4, it flushes the inside. After the flushing is completed, the water source falls directly into the receiving cylinder. Finally, they open the valve 21 at the bottom of the receiving cylinder 3 to collect the flushed water.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
