Description

Technical Field

[0001] This invention relates to the field of concrete processing technology, and in particular to a device for adding self-compacting admixtures to concrete. Background Technology

[0002] Concrete is a widely used basic material in modern construction engineering. Self-compacting concrete is a new type of concrete with high fluidity, anti-segregation and self-filling ability. It can be fully compacted under its own weight without vibration. Its core lies in the addition of self-compacting admixtures, such as high-efficiency water-reducing agents and thickeners, to significantly improve the rheological properties of the paste and ensure that the concrete is uniformly filled in complex structures.

[0003] Existing admixture addition systems typically consist of storage tanks, pumps, and pipelines. Their system structure is dispersed, occupies a large space, and is not conducive to the compact layout of mixing plants. Secondly, after prolonged use, residues are easily generated inside the storage tank, which can affect the effectiveness of admixtures and may also lead to cross-contamination. However, existing storage tanks are mostly installed in a fixed layout, making cleaning and maintenance extremely inconvenient.

[0004] Based on this, in order to optimize the maintenance convenience of existing additive equipment, we propose an additive equipment for self-compacting concrete admixtures. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing liquid storage tanks, which are mostly fixed in installation and therefore extremely inconvenient to clean and maintain, and to propose a device for adding self-compacting concrete admixtures.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design a device for adding a self-compacting concrete admixture, comprising: A frame with a lower shelf and an upper shelf; A slide table is slidably connected above the lower plate, and a locking assembly is provided between the slide table and the lower plate. A liquid storage tank is also fixedly installed above the slide table. A liquid pump is fixedly installed above the upper plate, and the liquid pump is connected to the liquid storage tank through a pipeline assembly. A spraying assembly is also installed in front of the frame, and the spraying assembly is connected to the liquid pump pipeline.

[0007] Furthermore, a stirring rod is rotatably connected inside the liquid storage tank, and a motor is fixedly installed on the side of the liquid storage tank, with the shaft end of the motor and the shaft end of the stirring rod fixedly connected.

[0008] Furthermore, the locking assembly includes a U-shaped rod, and two sliding grooves are formed on the end face of the slide table, with the two ends of the U-shaped rod slidably connected in the two sliding grooves respectively; The U-shaped rod is fixedly installed with a limiting block below the slide table. A first spring is fixedly installed between the limiting block and the bottom of the slide table. A locking block is fixedly installed above the lower plate. The side of the locking block has a slot that engages with the bottom end of the U-shaped rod.

[0009] Furthermore, the piping assembly includes a mounting plate fixedly installed below the frame, and a male connector is fixedly installed on the end face of the mounting plate. The male connector is connected to the input end of the liquid pump through a pipe. A female connector is fixedly installed on the side of the liquid storage tank, and the male connector and the female connector are plugged into each other and can be detachably connected.

[0010] Furthermore, a number of limiting beads are movably inserted into the outer periphery of the female head, and an abutment sleeve is movably connected to the outer side of the female head through a second spring, the abutment sleeve abutting against the limiting beads and moving inward; An annular groove adapted to the limiting bead is provided on the outer side of the male head.

[0011] Furthermore, a sealing head is movably inserted into the inside of the female head, and an inner recessed opening adapted to the sealing head is formed on the open side of the female head. A third spring is installed between the inner walls of the sealing head and the female head, and an abutment rod that abuts against the sealing head is fixedly installed inside the male head.

[0012] Furthermore, a driving component is provided between the abutment sleeve and the limiting block, the driving component being used to drive the abutment sleeve to move.

[0013] Furthermore, the drive assembly includes a sleeve fixedly installed at the lower end of the slide, a drive rod slidably connected to the inner side of the sleeve, a fourth spring fixedly installed between the drive rod and the sleeve, a connecting end formed at one end of the drive rod, the connecting end being fixedly connected to the abutting sleeve, a drive groove provided at the other end of the drive rod, and a top rod abutting the inclined surface of the drive groove being fixedly installed on the side of the limiting block.

[0014] Furthermore, the spraying assembly includes two guide rods fixedly installed at the front end of the frame, a mounting base slidably connected between the two guide rods, a spraying pipe fixedly installed at the front end of the mounting base, and the mounting base being locked and fixed to the guide rods by fasteners.

[0015] Furthermore, the upper end of the liquid storage tank and the bottom of the upper plate are separated by a predetermined distance, and the liquid storage tank is connected to the slide table through a bracket and a locking device.

[0016] The present invention proposes an additive device for self-compacting concrete, which has the following advantages: By adopting a stacked layout of the storage tank and the pump, the horizontal space occupied by the device is significantly reduced; at the same time, by using a sliding table to support the storage tank, the sliding table can be pulled outward when cleaning or maintenance is required, thereby moving the entire storage tank out of the equipment frame. This design greatly simplifies the cleaning and maintenance process inside the storage tank and effectively improves the convenience of maintenance. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Reference Figure 1-9As an embodiment of the present invention, a concrete self-compacting admixture adding device is disclosed. Specifically, the adding device includes a frame 1 having a lower plate 11 and an upper plate 12. Of course, in order to facilitate the movement of the frame 1, casters can also be installed at the bottom of the frame 1 in this embodiment, so that the frame 1 can be moved to the concrete to be processed. A slide table 2 is slidably connected above the lower plate 11. Optionally, in this embodiment, the slide table 2 can be slidably connected to the lower plate 11 via a guide rail and a slider assembly. A locking assembly 3 is provided between the slide table 2 and the lower plate 11. The locking assembly 3 is used to lock and position the slide table 2. A liquid storage tank 4 is also fixedly installed above the slide table 2. A liquid pump 5 is fixedly installed above the upper plate 12. The liquid pump 5 is connected to the liquid storage tank 4 via a pipeline assembly 6. A spraying assembly 7 is also installed in front of the frame 1. The spraying assembly 7 is connected to the liquid pump 5 via a pipeline.

[0021] Specifically, by adopting a stacked layout of the liquid storage tank 4 and the liquid pump 5, the horizontal space occupied by the equipment is significantly reduced. At the same time, by using a slide table 2 to support the liquid storage tank 4, when cleaning or maintenance is required, the slide table 2 can be pulled outward, thereby moving the liquid storage tank 4 out of the equipment frame 1 as a whole. This design greatly simplifies the cleaning and maintenance process of the inside of the liquid storage tank 4 and effectively improves the convenience of maintenance.

[0022] In some embodiments, a stirring rod 41 is rotatably connected inside the liquid storage tank 4 of the present invention, and a motor 42 is fixedly installed on the side of the liquid storage tank 4, with the shaft end of the motor 42 and the shaft end of the stirring rod 41 fixedly connected.

[0023] Since admixtures are generally composed of water-reducing agents as the core component, and other components such as viscosity modifiers and stabilizers are also compounded, in order to fully integrate the various components in the admixture, the present invention uses a stirring rod 41 designed inside the storage tank 4 to ensure the full mixing of the admixture.

[0024] Furthermore, in this embodiment, the locking assembly 3 includes a U-shaped rod 31, and two sliding grooves 21 are formed on the end face of the slide table 2. The two ends of the U-shaped rod 31 are slidably connected in the two sliding grooves 21 respectively. The U-shaped rod 31 is fixedly installed with a limiting block 32 below the slide table 2. A first spring 33 is fixedly installed between the limiting block 32 and the bottom of the slide table 2. A locking block 34 is fixedly installed above the lower plate 11. The side of the locking block 34 has a slot that engages with the bottom end of the U-shaped rod 31.

[0025] It should be noted that, in this embodiment, the U-shaped rod 31 is also provided with stop portions at both ends. The stop portions and the limiting blocks 32 are located on both sides of the slide table 2, respectively, to limit the vertical position of the U-shaped rod 31.

[0026] When it is necessary to pull the slide 2 and the liquid storage tank 4 outward for cleaning and maintenance, the U-shaped rod 31 can be pulled horizontally. At this time, the bottom end of the U-shaped rod 31 separates from the latch on the side of the locking block 34, thus unlocking the position of the slide 2. At this time, pulling the slide 2 outward will control its outward movement.

[0027] Based on the above embodiments, the pipeline assembly 6 in this embodiment includes a mounting plate 61 fixedly installed below the frame 1, and a male connector 62 is fixedly installed on the end face of the mounting plate 61. The male connector 62 is connected to the input end of the liquid pump 5 through a pipe 63. A female connector 64 is fixedly installed on the side of the liquid storage tank 4. The male connector 62 and the female connector 64 are plugged into each other and are detachably connected. Of course, in this embodiment, the female connector 64 should be installed and connected near the inner bottom surface of the liquid storage tank 4 to ensure that the admixture inside can be extracted. In addition, a sealing ring can be provided inside the female connector 64 to improve the sealing performance of the connection between it and the male connector 62. This method is a conventional technical means for those skilled in the art and will not be described in detail here.

[0028] In an optional embodiment, the outer periphery of the female head 64 in this invention is movably connected with a plurality of limiting beads 65, that is, a plurality of ball holes are opened on the outer side of the female head 64, and the inner end of the ball holes has a stop portion for the inward retraction of the limiting beads 65, so as to prevent the limiting beads 65 from falling off. The outer side of the female head 64 is movably connected to an abutment sleeve 66 through a second spring 60, and the abutment sleeve 66 abuts against the limiting beads 65 and moves inward. An annular groove 67 adapted to the limiting bead 65 is provided on the outer side of the male head 62.

[0029] During the specific connection, first pull the abutment sleeve 66 outward. In this embodiment, the inner end of the abutment sleeve 66 has a clearance opening. When the abutment sleeve 66 moves to the point where the clearance opening and the limiting bead 65 are directly opposite each other, the limiting bead 65 has radial movement space. At this time, the slide 2 can be pulled outward to separate the female head 64 on the side of the liquid storage tank 4 from the male head 62 on the mounting plate 61. Similarly, when the slide 2 moves inward to reset, after the male head 62 and the female head 64 are inserted, release the pressure on the abutment sleeve 66. The inner wall of the abutment sleeve 66 abuts against the limiting bead 65 to move it inward until the inner part of the limiting bead 65 is engaged in the annular groove 67 of the male head 62. In this way, the connection and adaptation between the male head 62 and the female head 64 can be completed.

[0030] Based on the above embodiments, in this embodiment, a sealing head 68 is movably inserted into the female head 64, and an inner recess 641 adapted to the sealing head 68 is formed on the open side of the female head 64. In the initial state, the sealing head 68 and the inner recess 641 are in contact and sealed to prevent the additive in the liquid storage tank 4 from flowing out. A third spring 69 is installed between the inner walls of the sealing head 68 and the female head 64, and an abutment rod 621 that abuts against the sealing head 68 is fixedly installed inside the male head 62.

[0031] In other words, in this embodiment, by installing a sealing head 68 inside the female head 64, when the male head 62 and the female head 64 are not connected, the sealing head 68, in conjunction with the inner retraction port 641, seals the female head 64 to prevent the additive from flowing out. When the slide 2 is reset, the male connector 62 and the female connector 64 are plugged into each other and connected. At the same time, the abutment rod 621 inside the male connector 62 will abut against the sealing head 68 and move inward, thus realizing the connection of the internal pipes of the male connector 62 and the female connector 64.

[0032] In order to achieve convenient movement control of the abutment sleeve 66 and improve the ease of operation of the slide table 2 when it is pulled outward, a driving component 8 is also provided between the abutment sleeve 66 and the limiting block 32 in this embodiment of the invention. The driving component 8 is used to drive the abutment sleeve 66 to move.

[0033] Specifically, in this embodiment, the driving assembly 8 includes a sleeve 81 fixedly installed at the lower end of the slide table 2. A driving rod 82 is slidably connected to the inner side of the sleeve 81. A fourth spring 83 is fixedly installed between the driving rod 82 and the sleeve 81. One end of the driving rod 82 is formed with a connecting end 84, which is fixedly connected to the abutting sleeve 66. The other end of the driving rod 82 is provided with a driving groove 85. A top rod 86 that abuts against the inclined surface of the driving groove 85 is fixedly installed on the side of the limiting block 32.

[0034] In other words, when the liquid storage tank 4 needs to be pulled outward for maintenance, the U-shaped rod 31 needs to be pulled laterally first. At this time, the bottom end of the U-shaped rod 31 will separate from the locking block 34 to unlock the position of the slide table 2. Meanwhile, when the U-shaped rod 31 moves laterally, the top rod 86 on a limiting block 32 at its bottom will abut against the driving groove 85 on the driving rod 82. With the help of the inclined surface between the two, the entire driving rod 82 is controlled to move forward. As can be seen from the above connection structure between the male head 62 and the female head 64, since the driving rod 82 is fixedly connected to the connecting end 84 and the abutment sleeve 66, when the driving rod 82 moves, it will drive the abutment sleeve 66 to move laterally. When the abutment sleeve 66 moves, it will unlock the limiting bead 65, that is, complete the unlocking operation between the male head 62 and the female head 64. At this time, the slide table 2 can be pulled out freely to pull the entire liquid storage tank 4 outward for convenient maintenance.

[0035] In some embodiments, the spraying assembly 7 of the present invention includes two guide rods 71 ​​fixedly installed at the front end of the frame 1, and a mounting base 72 is slidably connected between the two guide rods 71. A spraying pipe 73 is fixedly installed at the front end of the mounting base 72. The mounting base 72 is locked and fixed to the guide rods 71 ​​by fasteners 74. Specifically, the spraying pipe 73 of the present invention is connected to the liquid pump 5 through a hose. The fastener 74 is a bolt, which locks the upper and lower positions of the mounting base 72, thereby enabling the height of the entire spraying pipe 73 to be adjusted. In actual operation, the liquid pump 5 delivers the admixture in the storage tank 4 into the spraying pipe 73, and then sprays it into the concrete raw materials, thus completing the admixture addition operation.

[0036] It should be noted that, in this embodiment of the invention, the upper end of the liquid storage tank 4 and the bottom of the upper plate 12 are separated by a predetermined distance. This predetermined distance facilitates the user in adding the admixture into the liquid storage tank 4. In addition, in this embodiment, the liquid storage tank 4 is connected to the slide table 2 through a bracket and a locking component. Specifically, the locking component in this embodiment is also set as a bolt. By using bolt installation, the entire liquid storage tank 4 can be easily installed and disassembled, thereby further optimizing the convenience of its maintenance. In practice, the admixture is first added to the inside of the storage tank 4, and then stirred thoroughly by the stirring rod 41 in the storage tank 4. Then, the device is moved to the concrete material to be added, and the liquid pump 5 is started to spray the admixture in the storage tank 4 into the concrete material by the spraying component 7. In this way, the admixture addition operation can be completed.

[0037] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
