Description

Technical Field

[0001] This utility model relates to the technical field of concrete mixing plant equipment, and in particular to a novel scale washing device. Background Technology

[0002] Currently, accurate material metering is a crucial step in ensuring concrete quality during the production process of concrete batching plants. Water scales are used to accurately measure the production water required for mixing, and then pump the metered water directly into the concrete mixing unit via a pressure pump. However, batching plants typically also have wastewater scales, which collect and measure wastewater containing residual concrete (accumulated material) generated during the cleaning of the mixing unit, mixer trucks, or site. This wastewater is then reused in subsequent mixing processes to achieve resource conservation and environmental protection.

[0003] However, wastewater scales have a significant problem in practical use: solid particles (accumulated material) in wastewater easily deposit and clump on the inner wall and bottom of the scale hopper, especially near the pipe inlet. If these accumulated materials are not cleaned in time, they will not only clog the pipes and affect the measurement accuracy and emptying effect of the wastewater scale, but in severe cases, they may even cause equipment failure, requiring frequent manual cleaning, increasing maintenance costs and downtime. Traditional solutions, such as setting up dedicated cleaning nozzles or using additional high-pressure water flushing, can alleviate the accumulation problem, but they often require additional cleaning water sources, power (such as adding water pumps), and control systems, increasing equipment complexity and energy consumption, resulting in poor economic efficiency.

[0004] Therefore, how to effectively solve the problem of material accumulation inside the sewage weigher without increasing additional energy consumption and equipment complexity, ensure the smoothness and accuracy of its metering and discharge, and maintain the stability of the proportion of the entire mixing system, has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] The purpose of this invention is to provide a novel scale washing device that effectively solves the problem of material accumulation inside a sewage scale without increasing energy consumption and equipment complexity, ensuring the smoothness and accuracy of its metering and discharge, and maintaining the stability of the proportions of the entire mixing system.

[0006] To achieve the above objectives, this utility model provides a novel scale washing device, comprising:

[0007] A water scale, wherein the bottom of the water scale is provided with a first water outlet pipe;

[0008] The wastewater scale has a second outlet pipe at its bottom, and the end of the second outlet pipe away from the wastewater scale is connected to the concrete mixing host.

[0009] A water pump is connected to the end of the first water outlet pipe furthest from the water scale.

[0010] A water supply main pipe, the end of which is away from the water pump is connected to the concrete mixing host;

[0011] A water supply branch pipe, one end of which is connected to the main water supply pipe and the other end of which is connected to the sewage scale;

[0012] The water pump is used to send a portion of the clean water measured by the clean water scale into the concrete mixing host through the main water supply pipe, and to return another portion of the clean water to the sewage scale through the branch water supply pipe. The clean water in the sewage scale mixes with the accumulated material and then enters the concrete mixing host through the second outlet pipe.

[0013] In a preferred embodiment, the first water outlet pipe is provided with a first valve, the second water outlet pipe is provided with a second valve, and the main water supply pipe is provided with a third valve.

[0014] In a preferred embodiment, the sewage scale is installed at a higher height than the clean water scale.

[0015] In a preferred embodiment, the water supply branch pipe includes a first vertical pipe, a horizontal pipe, and a second vertical pipe connected end to end in sequence; the end of the first vertical pipe away from the horizontal pipe is connected to the main water supply pipe, and the end of the second vertical pipe away from the horizontal pipe is located above the sewage scale.

[0016] In a preferred embodiment, the end of the second vertical pipe away from the horizontal pipe is provided with a downwardly curved guide bend.

[0017] In a preferred embodiment, the bottom of the horizontal tube is supported by a first bracket and a second bracket, respectively.

[0018] In a preferred embodiment, the system further includes a support plate, on which connecting rods are provided vertically upward on both opposite sides, and a locking attachment is provided at the top of the connecting rods; the water pump is fixed to the support plate.

[0019] This novel scale washing device utilizes a water pump to pressurize and pump the water measured by the clean water scale. A portion of this water is directly fed into the mixing host via the main water supply pipe, while the other portion flows back to the wastewater scale via a branch pipe. This pressurized backflow effectively flushes the inner wall and bottom (especially the inlet area of ​​the second outlet pipe) of the wastewater scale, dissolving or washing away deposited material. This fundamentally prevents the formation and compaction of material within the wastewater scale, ensuring accurate measurement and smooth discharge. The flushed-down material mixes with the clean water entering the wastewater scale, forming a wastewater mixture. This mixture is also transported to the concrete mixing host via the second outlet pipe at the bottom of the wastewater scale. Since this clean water and the material it carries away (which is originally a concrete component) ultimately enter the host for mixing, the total amount of water and solid material entering the host remains unchanged, ensuring the accuracy of the concrete mix proportions. The entire flushing process utilizes a portion of the production water already measured by the clean water scale, powered by the pressure provided by the same water pump that transports the production water. No additional water source, pump, or specialized high-pressure cleaning equipment is required; it fully utilizes the energy of the existing metering and transport system, resulting in energy conservation and environmental protection. Furthermore, this invention only adds a water supply branch pipe to the existing pipeline system, requiring minimal structural modifications, making it easy to implement and maintain, highly reliable, and significantly reducing or even eliminating the frequency and difficulty of manually cleaning the wastewater scale, thus lowering equipment maintenance costs and downtime.

[0024] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described in this specification are merely for explaining the present utility model and are not intended to limit the present utility model.

[0025] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0026] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0027] In the embodiments of this utility model, a novel washing scale device 100 is provided, which can measure both clean water and sewage, and effectively solve the problem of material accumulation inside the sewage scale 20 without increasing additional energy consumption and equipment complexity, ensuring the smoothness and accuracy of its measurement and discharge, and maintaining the stability of the proportion of the entire mixing system.

[0028] like Figure 1 and Figure 2 As shown, the new type of scale washing device 100 includes: a clean water scale 10, a sewage scale 20, a water pump 30, a main water supply pipe 40, and a branch water supply pipe 50.

[0029] The bottom of the water scale 10 is provided with a first water outlet pipe 11, through which the metered water can be discharged. The first water outlet pipe 11 is provided with a first valve 12, which can be a manual butterfly valve to control the opening and closing of the first water outlet pipe 11.

[0030] The wastewater scale 20 has a second outlet pipe 21 at its bottom, and the end of the second outlet pipe 21 away from the wastewater scale 20 is connected to the concrete mixing host (not shown in the figure). Therefore, the metered wastewater and the mixture of wastewater after cleaning can be transported to the concrete mixing host through the second outlet pipe 21. The second outlet pipe 21 is equipped with a second valve 22, which can be a manual butterfly valve to control the opening and closing of the second outlet pipe 21.

[0031] In this embodiment, the sewage scale 20 is installed at a higher height than the clean water scale 10, so that the sewage or sewage mixture delivered by the sewage scale 20 can be fed into the concrete mixing host by its own gravity. It should be noted that the implementation principle and specific implementation method of water metering by the clean water scale 10 and the sewage scale 20 can refer to the prior art, and will not be repeated here.

[0032] Pump 30 is a booster pump and is connected to the end of the first outlet pipe 11 furthest from the clean water scale 10. Therefore, the clean water measured by the clean water scale 10 will be pumped to the main water supply pipe 40 via pump 30. The end of the main water supply pipe 40 furthest from pump 30 is connected to the concrete mixing host. The main water supply pipe 40 is equipped with a third valve 41, which is used to control the on / off state of the main water supply pipe 40.

[0033] One end of the water supply branch pipe 50 is connected to the main water supply pipe 40, and the other end is connected to the sewage scale 20. The water pump 30 is used to send a portion of the clean water measured by the clean water scale 10 into the concrete mixing host through the main water supply pipe 40, and to return another portion of the clean water to the sewage scale 20 through the water supply branch pipe 50, so that the sewage mixture formed by the clean water and accumulated materials in the sewage scale 20 enters the concrete mixing host through the second outlet pipe 21.

[0034] Therefore, a portion of the clean water is directly fed into the mixing host through the main water supply pipe 40 via the conventional path, while the other portion of the clean water actively flows back into the sewage scale 20 through the branch water supply pipe 50 branching off from the main water supply pipe 40. This returning clean water is pressurized and, upon entering the sewage scale 20, can effectively flush its inner walls and bottom.

[0035] Specifically, the water supply branch pipe 50 includes a first vertical pipe 51, a horizontal pipe 52, and a second vertical pipe 53 connected end to end. The bottom of the horizontal pipe 52 is supported by a first support 521 and a second support 522 on both sides, respectively. The end of the first vertical pipe 51 away from the horizontal pipe 52 is connected to the main water supply pipe 40, and the end of the second vertical pipe 53 away from the horizontal pipe 52 is located above the sewage scale 20. Further, the end of the second vertical pipe 53 away from the horizontal pipe 52 is provided with a downwardly curved guide bend 54.

[0036] Furthermore, the novel scale washing device 100 also includes a support plate 60. Connecting rods 61 are vertically upwardly arranged on both opposite edges of the support plate 60, and locking attachments 62 are provided at the top of the connecting rods 61. The water pump 30 is fixed to the support plate 60. Therefore, the connecting rods 61 can be suspended in a predetermined position by the locking attachments 62, thereby suspending and fixing the water pump 30 to absorb vibrations during operation and reduce vibration noise.

[0037] In summary, the novel scale washing device 100 provided by this utility model pumps the clean water measured by the clean water scale 10 under pressure by the water pump 30. A portion of the clean water is directly sent to the mixing host via the main water supply pipe 40 through a conventional path, while the other portion flows back to the sewage scale 20 through the branch water supply pipe 50 branching off from the main water supply pipe 40. This returning clean water, under pressure, effectively flushes the inner wall and bottom of the sewage scale 20 (especially the inlet area of ​​the second outlet pipe 21), dissolving or washing away deposited material, fundamentally preventing the formation and compaction of material inside the sewage scale 20, and ensuring the measurement accuracy and smooth discharge of the sewage scale 20. The flushed-down material mixes with the clean water entering the sewage scale 20 to form a sewage mixture. This mixture is also transported to the concrete mixing host through the second outlet pipe 21 at the bottom of the sewage scale 20. Since this portion of clean water and the accumulated material it carries away (which was originally a component of concrete) ultimately enter the main unit for mixing, the total amount of water and solid material entering the main unit remains unchanged, ensuring the accuracy of the concrete mix proportions. The water source used in the entire flushing process is a portion of the production water already measured by the clean water scale 10, and the power source is the pressure provided by the same water pump that transports the production water. No additional water source, pump, or specialized high-pressure cleaning equipment is required; the energy of the existing metering and conveying system is fully utilized, resulting in energy conservation and environmental protection. Furthermore, this invention only adds a water delivery branch pipe 50 to the existing pipeline system, resulting in minimal structural modifications, ease of implementation and maintenance, high reliability, and significantly reducing or even eliminating the frequency and difficulty of manually cleaning the wastewater scale 20, thus lowering equipment maintenance costs and downtime.

[0038] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
