Description

Technical Field

[0001] This utility model relates to the field of building material production equipment, and in particular to a storage device for polycarboxylate long-acting water-reducing agent with a filter for impurities. Background Technology

[0002] Polycarboxylate superplasticizers are mostly water-based liquids, and some products may contain small amounts of alkaline or functional additives. When storing them, it is crucial to address issues such as corrosion prevention, contamination prevention, stratification prevention, and ease of access. Storage equipment must be tailored to the storage capacity, site conditions, and intended use.

[0003] Polycarboxylate superplasticizer storage equipment often requires auxiliary components to ensure its operation: First, a stirring device, usually a vertical stirring paddle, is used to stir regularly to prevent the agent from separating; second, a liquid level monitoring device, such as a float level gauge or radar level gauge, is used to display the storage volume in real time to avoid material shortage or overflow; third, corrosion-resistant valves and pipes are required, and the valves and conveying pipes must be made of PE, PP or plastic-lined materials that are compatible with the material of the storage tank to prevent pipeline corrosion and contamination of the agent; fourth, sealing and breather valves are used to reduce air entry and balance the air pressure inside the tank to prevent tank deformation.

[0004] The storage equipment for polycarboxylate superplasticizers has the following drawbacks: the performance of polycarboxylate superplasticizers depends on the stability of their molecular structure and the uniformity of their composition. During storage or transportation, various impurities are easily mixed in, such as dust and sand brought in during transportation, debris detached from the inner wall of the storage equipment due to aging (such as fragments of the plastic lining), and even a small amount of precipitated particles that precipitate out during long-term storage. If superplasticizers containing impurities are added to concrete mixing, the impurities will directly affect the performance of the concrete. On the one hand, solid impurities such as sand and metal fragments will destroy the uniformity of the internal structure of the concrete, resulting in honeycomb and pitted surfaces after pouring, and reducing the density of the concrete. Therefore, a polycarboxylate superplasticizer storage equipment with a filter for impurities is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above deficiencies, this utility model provides a polycarboxylate long-acting water-reducing agent storage device with a filter for impurities. It aims to improve the problem of a small amount of precipitated particles that precipitate out during long-term storage of water-reducing agents in the prior art. If water-reducing agents containing impurities are added to concrete mixing, the impurities will directly affect the performance of the concrete. On the one hand, solid impurities such as sand and metal fragments will destroy the uniformity of the internal structure of the concrete.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a polycarboxylate long-lasting water-reducing agent storage device with a filtration device, comprising a main body of the water-reducing agent storage device and a discharge valve. The discharge valve is fixedly connected to the bottom outer wall of the main body of the water-reducing agent storage device. An adjustment mechanism is provided on the discharge valve, which is an auxiliary mechanism provided on the main body of the water-reducing agent storage device. The adjustment mechanism includes a diversion pipe, which is fixedly connected to the side outer wall of the discharge valve. A splicing cylinder is threadedly fixed to the side outer wall of the diversion pipe. A filter screen is fixedly connected to the side inner wall of the splicing cylinder. A connecting pipe groove is opened on the left inner wall of the splicing cylinder. An opening and closing groove is opened on the side inner wall of the diversion pipe. A threaded rod is rotatably connected to the bottom inner wall of the opening and closing groove through a bearing. An adjustment disc is fixedly connected to the bottom end of the threaded rod. A threaded sleeve is threadedly connected to the side outer wall of the threaded rod. A sealing silicone plate is fixedly connected to the side outer wall of the threaded sleeve.

[0007] As a further description of the above technical solution: the auxiliary mechanism includes a base frame, which contacts the bottom outer wall of the main body of the water-reducing agent storage device. A protective frame is fixedly connected to the top outer wall of the base frame, and a cushioning cotton pad is fixedly connected to the inner side wall of the protective frame. A roller is fixedly connected to the bottom inner wall of the base frame, and a positioning hole is opened on the front inner wall of the base frame. A threaded post is threadedly connected to the inner ring inner wall of the positioning hole.

[0008] As a further description of the above technical solution: there are two diversion pipes, and the two diversion pipes are respectively fixedly connected to the outer walls of the left and right sides of the discharge valve.

[0009] As a further description of the above technical solution: a pipe is threadedly fixed to the inner side wall of the connecting pipe groove, the pipe is connected to the diversion pipe, and the diversion pipe is connected to the discharge valve.

[0010] As a further description of the above technical solution: the sealing silicone plate is slidably connected to the inner walls of the left and right sides of the opening and closing groove, and a frosted pad is fixedly connected to the outer side wall of the adjusting plate.

[0011] As a further description of the above technical solution: the cushioning cotton pad contacts the outer side wall of the main body of the water-reducing agent storage device, and there are several positioning holes, which are respectively opened on the outer side wall of the roller and the base frame.

[0012] As a further description of the above technical solution: an annular handle is fixedly connected to the outer side wall of the threaded column, and a silicone sleeve is fixedly connected to the outer side wall of the annular handle.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the filter components in the adjustment mechanism can effectively filter impurities and particles in the water-reducing agent, ensuring the purity of the output. At the same time, the multi-channel diversion design allows the work to continue through other channels while a single channel is being maintained, avoiding work interruptions caused by maintenance and improving the continuity of equipment operation.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3This utility model provides an embodiment of a long-lasting polycarboxylate superplasticizer storage device with a filtration device. The device includes a main body 1 and a discharge valve 2. The discharge valve 2 is fixedly connected to the bottom outer wall of the main body 1. An adjustment mechanism 3 is provided on the discharge valve 2. An auxiliary mechanism 4 is provided on the main body 1. The adjustment mechanism 3 includes a diversion pipe 31, which is fixedly connected to the side outer wall of the discharge valve 2. The diversion pipe 31 can introduce the superplasticizer discharged from the discharge valve 2 into a diversion channel, ensuring that the superplasticizer can smoothly enter the filtration stage. A splicing cylinder 32 is threadedly fixed to the side outer wall of the diversion pipe 31. A filter screen 33 is fixedly connected to the side inner wall of the splicing cylinder 32. The filter screen 33 is fixed to the inner wall of the splicing cylinder 32 and can filter the passing superplasticizer, blocking impurities. Impurities and particles are removed to ensure the purity of the discharged water-reducing agent. The inner left side wall of the splicing cylinder 32 is provided with a connecting pipe groove 34, and the inner side wall of the diversion pipe 31 is provided with an opening and closing groove 35. The opening and closing groove 35 is located on the inner wall of the diversion pipe 31, providing space and a guide track for the sliding of the sealing silicone plate 38, ensuring the stable movement of the sealing silicone plate 38. The bottom inner wall of the opening and closing groove 35 is rotatably connected to a threaded rod 36 through a bearing. The bottom end of the threaded rod 36 is fixedly connected to an adjusting plate 37. The outer side wall of the threaded rod 36 is threadedly connected to a threaded sleeve. The outer side wall of the threaded sleeve is fixedly connected to the sealing silicone plate 38. The threaded sleeve moves up and down with the rotation of the threaded rod 36, thereby driving the sealing silicone plate 38 to move. The sealing silicone plate 38 can tightly fit the inner wall of the opening and closing groove 35 to achieve sealing or opening of the channel between the diversion pipe 31 and the discharge valve 2.

[0019] Reference Figures 2-4 There are two diversion pipes 31, which are fixedly connected to the outer walls of the left and right sides of the discharge valve 2. The inner wall of the connecting pipe groove 34 is threaded with a pipe. The connecting pipe groove 34 is threaded with the pipe and the pipe is connected to the diversion pipe 31 to ensure that the filtered water-reducing agent can be smoothly transported through the pipe. The pipe is connected to the diversion pipe 31 and the diversion pipe 31 is connected to the discharge valve 2. The sealing silicone plate 38 is slidably connected to the inner walls of the left and right sides of the opening and closing groove 35. The outer wall of the adjusting plate 37 is fixedly connected with a frosted pad. The frosted pad on the side of the adjusting plate 37 can increase the friction between the hand and the adjusting plate 37.

[0020] Reference Figures 3-4The auxiliary mechanism 4 includes a base frame 41, which contacts the bottom outer wall of the main body 1 of the water-reducing agent storage device. A protective frame 42 is fixedly connected to the top outer wall of the base frame 41, and a cushioning pad 43 is fixedly connected to the inner side wall of the protective frame 42. The cushioning pad 43 is fixed to the inner wall of the protective frame 42. When the main body 1 of the water-reducing agent storage device is impacted by an external force, it can cushion the impact force through its own elasticity, further protecting the main body 1 of the water-reducing agent storage device. A roller 44 is fixedly connected to the bottom inner wall of the base frame 41, and the front inner wall of the base frame 41... A positioning hole 45 is provided, and a threaded post 46 is threadedly connected to the inner wall of the inner ring of the positioning hole 45. A cushioning cotton pad 43 contacts the outer side wall of the main body 1 of the water-reducing agent storage device. There are several positioning holes 45, which are respectively opened on the outer side walls of the roller 44 and the base frame 41. A ring handle is fixedly connected to the outer side wall of the threaded post 46, and a silicone sleeve is fixedly connected to the outer side wall of the ring handle. The silicone sleeve and ring handle facilitate the operator to rotate the threaded post 46. The silicone sleeve can increase hand comfort and prevent slippage during rotation.

[0021] Working principle: When discharge is required, the splicing cylinder 32 is connected to the diversion pipe 31, and then the existing pipe is connected to the connecting pipe groove 34. Then, the adjusting disc 37 is rotated to rotate the threaded rod 36. The rotation of the threaded rod 36 drives the sealing silicone plate 38 to move. The moving sealing silicone plate 38 opens the opening between the diversion pipe 31 and the discharge valve 2, allowing the internal water-reducing agent to flow through the diversion pipe 31 and then to the filter screen 33 to filter and block impurities and particles in the water-reducing agent, ensuring that the purity of the discharged water-reducing agent reaches the optimal level. Meanwhile, when a single diversion pipe 31 becomes blocked or the filter screen 33 needs to be disassembled and cleaned, another diversion pipe 31 can be opened alternately to avoid the problem of work interruption due to maintenance. At the same time, when the main body 1 of the water-reducing agent storage equipment needs to be moved as a whole, the rollers 44 facilitate personnel to move it. At the same time, by threading the threaded post 46 to the positioning hole 45, the rollers 44 are limited to prevent the main body 1 of the water-reducing agent storage equipment from being moved when placed on a steep slope or uneven road section, which could lead to collision or overturning damage.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
