Description

TECHNICAL FIELD

The water in the construction site is usually collected directly into the pool by a submersible pump. This method has the following problems: 1. The pool is generally at a low level, and the stirring station is at a high level. Therefore, the water needs to be lifted and delivered to the stirring station by a pressure pump.

Therefore, the water needs to be lifted and delivered to the stirring station by a pressure pump.

[0005] To achieve the above-mentioned purpose, the present utility model is realized by the following technical solutions:

[0006] A stirring station water delivery system includes a water storage mechanism, a stirring mechanism, and a stirring water tank arranged between the water storage mechanism and the stirring mechanism. The horizontal heights of the water storage mechanism, the stirring mechanism, and the stirring water tank increase in turn. The water storage mechanism and the stirring water tank are connected by a water outlet pipe. The stirring water tank and the stirring mechanism are connected by a water inlet pipe. The stirring water tank includes a water bucket, a stirring assembly arranged in the water bucket, a coarse material filtering assembly arranged on the inner side wall of the water bucket, and a fine material filtering assembly arranged at the bottom wall of the water bucket. The fine material filtering assembly includes a fine material outlet channel passing through the bottom wall of the water bucket, a blocking structure located below the fine material outlet channel, and a fine material collection tank located below the blocking structure. The stirring assembly and the blocking structure are connected by a synchronous mechanism. The stirring assembly rotates to block or release the fine material outlet channel.

[0007] According to an aspect of the above technical solution, the stirring assembly comprises a first rotating shaft located in the water bucket, a motor connected to the first rotating shaft, a spiral blade arranged on the first rotating shaft, and a brush washing assembly arranged at the bottom end of the first rotating shaft.

[0008] According to an aspect of the above technical solution, the brush washing assembly comprises a horizontal rod arranged perpendicularly to the first rotating shaft, and a brush arranged below the horizontal rod, the brush being in contact with the bottom wall of the water bucket.

[0009] According to an aspect of the above technical solution, the coarse material filtering assembly comprises a sliding block arranged vertically on the inner side wall of the water bucket, and a filter screen connected to the sliding block, the size of the mesh of the filter screen gradually decreases from top to bottom.

[0010] According to an aspect of the above technical solution, the blocking structure comprises a rotating drum and a second rotating shaft connected to the rotating drum, the rotating drum is provided with a first gap in the axial direction, the size of the first gap being consistent with that of the fine material outlet channel, and the fine material collection box is provided with a second gap at one end close to the fine material outlet channel, the size of the second gap being consistent with that of the fine material outlet channel.

[0011] According to an aspect of the above technical solution, the synchronous mechanism comprises a bearing seat arranged on the water bucket, a third rotating shaft arranged on the bearing seat, a first synchronous structure connecting the first rotating shaft and the third rotating shaft, and a second synchronous structure connecting the third rotating shaft and the second rotating shaft.

[0012] According to an aspect of the above technical solution, the first synchronous structure comprises a first belt pulley arranged on the first rotating shaft, a second belt pulley arranged on the second rotating shaft, and a belt structure connecting the first belt pulley and the second belt pulley.

[0013] According to an aspect of the above technical solution, the second synchronous structure comprises a first bevel gear arranged on the second rotating shaft, and a second bevel gear arranged on the third rotating shaft, the first bevel gear and the second bevel gear being meshed and connected.

[0014] According to an aspect of the above technical solution, the water storage mechanism comprises a water pool and a submersible pump arranged in the water pool, one end of the water outlet pipe being connected to the submersible pump.

[0015] According to an aspect of the above technical solution, the stirring mechanism comprises a stirring bucket and a water scale arranged in the stirring bucket, the outlet of the water inlet pipe being located directly above the water scale, the water inlet pipe being provided with a fine metering water outlet and a coarse metering water outlet close to the water scale.

[0016] Compared with the prior art, the beneficial effects of the present application are as follows:

[0017] By installing a mixing water tank between the water storage mechanism and the mixing mechanism, and with the horizontal heights of the water storage mechanism, mixing mechanism, and mixing water tank increasing sequentially, clean water from the water storage mechanism can be first introduced into the mixing water tank through the outlet pipe. When the mixing mechanism needs water, the valve in the mixing water tank is opened, and the water in the mixing water tank flows into the mixing mechanism through the inlet pipe by its own weight. This prevents the water pressure and flow rate from being too high due to the action of the booster pump, making the flow meter measurement more accurate and the amount of clean water more precise, thereby improving the strength of the concrete. At the same time, the mixing water tank is equipped with a mixing component, a coarse material filter component, and a fine material filter component. Impurities can be filtered in the mixing water tank before the clean water is sent to the mixing mechanism. Specifically, the mixing component rotates rapidly, and the vortex flow generated carries the coarse and fine materials upward. During the spiral rotation, the coarse materials are retained. In the filter assembly, fine particles, due to their small size, fall to the bottom of the bucket when the agitator stops rotating. The agitator then slows down, and the fine particles do not spiral upwards but rotate at the bottom of the bucket. During the rotation of the agitator, a synchronization mechanism causes the blocking structure to move as well. When the fine particles reach the fine particle outflow channel, the blocking structure moves to a state where it no longer obstructs the outflow, allowing the fine particles to flow into the fine particle collection box. This design can simultaneously clean both coarse and fine particles. If only one outflow channel is set at the bottom of the bucket to collect both coarse and fine particles, that channel would need to be very large, resulting in excessive water flowing through each time. The synchronization mechanism also eliminates the need for manual operation of the blocking structure, preventing excessive accumulation of fine particles in the outflow channel without the blocking structure opening in time, which would cause the fine particles to continuously flow in the water, resulting in poor cleaning performance.

[0027] The following detailed description will further describe the present application with reference to the above-mentioned drawings. DETAILED DESCRIPTION

[0028] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The drawings show several embodiments of the present application. However, the present application can be realized in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0029] It should be noted that when an element is referred to as being "fixed" to another element, it can be directly on the other element or there can be an intervening element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or there can be an intervening element. The terms "vertical", "horizontal", "left", "right", and similar expressions used herein are for illustrative purposes only.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0031] Please refer to Figures 1 to 7The diagram shows a water supply system for a mixing plant according to an embodiment of the present invention. It includes a water storage mechanism, a mixing mechanism, and a mixing tank located between the water storage mechanism and the mixing mechanism. The horizontal heights of the water storage mechanism, the mixing mechanism, and the mixing tank increase sequentially. The water storage mechanism and the mixing tank are connected by an outlet pipe 12, and the mixing tank and the mixing mechanism are connected by an inlet pipe 23. The mixing tank includes a water tank 20, a mixing assembly 28 disposed within the water tank 20, a coarse material filter assembly disposed on the inner wall of the water tank 20, and a fine material filter assembly disposed on the bottom wall of the water tank 20. The fine material filter assembly includes a fine material outflow channel 29 penetrating the bottom wall of the water tank 20, a blocking structure located below the fine material outflow channel 29, and a fine material collection box 22 located below the blocking structure. The mixing assembly 28 and the blocking structure are connected by a synchronization mechanism. The rotation of the mixing assembly 28 drives the blocking structure to block or release the fine material outflow channel 29.

[0032] Understandably, this utility model sets up a mixing water tank between the water storage mechanism and the mixing mechanism, with the horizontal heights of the water storage mechanism, the mixing mechanism, and the mixing water tank increasing sequentially. This allows clean water from the water storage mechanism to be input into the mixing water tank via the outlet pipe 12. When the mixing mechanism needs water, the valve in the mixing water tank is opened, and the water in the mixing water tank flows into the mixing mechanism through the inlet pipe 23 by its own weight. This prevents the water pressure and flow rate from being too high due to the action of the booster pump, making the flow meter measurement more accurate and the amount of clean water more precise, thereby improving the strength of the concrete. Simultaneously, the mixing water tank is equipped with a mixing component 28, a coarse material filter component, and a fine material filter component. Impurities can be filtered in the mixing water tank before the clean water is sent into the mixing mechanism. Specifically, the mixing component 28 is first rotated rapidly, and the generated vortex flow carries the coarse and fine materials upwards. During the spiral rotation, the coarse materials remain in the mixing water tank. In the filter assembly, fine particles, due to their small size, fall to the bottom of the water tank 20 when the stirring assembly 28 stops rotating. Then, the stirring assembly 28 is rotated slowly. The fine particles do not spiral upwards but rotate at the bottom of the water tank 20. During the rotation of the stirring assembly 28, the synchronization mechanism causes the blocking structure to move as well. When the fine particles reach the fine particle outflow channel 29, the blocking structure will also move to a state where it no longer blocks the fine particle outflow channel 29, allowing the fine particles to flow into the fine particle collection box 22. This design can clean both coarse and fine particles simultaneously. If only one outflow channel is set at the bottom of the water tank 20 to collect both coarse and fine particles at the same time, then the outflow channel needs to be very large, which would result in too much clean water flowing out each time. At the same time, the synchronization mechanism also eliminates the need for manual operation of the blocking structure, preventing too much fine particle from accumulating in the fine particle outflow channel 29 while the blocking structure does not open in time, causing the fine particles to keep flowing in the clean water, resulting in poor cleaning effect.

[0033] Specifically, in this embodiment, the stirring assembly 28 includes a first rotating shaft 281 located inside the water tank 20, a motor 21 connected to the first rotating shaft 281, a spiral blade 282 disposed on the first rotating shaft 281, and a scrubbing assembly disposed at the bottom end of the first rotating shaft 281; the scrubbing assembly includes a horizontal rod 283 disposed perpendicular to the first rotating shaft 281, and bristles 284 disposed below the horizontal rod 283, the bristles 284 contacting the bottom wall of the water tank 20. A cover 24 is provided above the water tank 20, and the motor 21 is fixed to the cover 24 by a mounting plate 27.

[0034] Understandably, when filtering impurities in the water bucket 20, the motor 21 is started to drive the first rotating shaft 281 and the spiral blade 282 to rotate rapidly, and the resulting vortex flow can cause the impurities to spiral upward. When the motor 21 drives the first rotating shaft 281 and the spiral blade 282 to rotate at a low speed, the impurities will not spiral upward, but will only be at the bottom of the water bucket 20. At this time, the horizontal bar 283 will drive the bristles 284 to rotate the fine material along the bottom wall of the water bucket 20 until it reaches the fine material outflow channel 29.

[0035] Furthermore, the coarse material filtration assembly includes a slider 32 vertically slidably disposed on the inner side wall of the water tank 20, and a filter screen 30 connected to the slider 32. The size of the mesh of the filter screen 30 decreases from top to bottom. The slider 32 slides in the groove 31 on the inner side wall of the water tank 20. It should be noted that the bottom of the filter screen 30 is closed and the top is open.

[0036] Understandably, since the mesh size of filter screen 30 decreases from top to bottom, coarse material will enter the higher parts of filter screen 30 during spiral flow, entering from the upper opening or the larger mesh area, and then falling downwards. The smaller mesh area can limit the escape of coarse material. This structure is similar to the dirt collection bag in a washing machine, which can greatly improve the collection efficiency of coarse material. The motor 21 can also be set to rotate in both directions to further enhance the mixing effect.

[0037] Preferably, this embodiment is designed with three filters 30, which are arranged at equal intervals along a ring.

[0038] Furthermore, the blocking structure includes a rotating drum 223 and a second rotating shaft 225 connected to the rotating drum 223. The rotating drum 223 is provided with a first notch 224 along the axial direction that is the same size as the fine material outflow channel 29. The fine material collection box 22 is provided with a second notch 222 that is the same size as the fine material outflow channel 29 at one end near the fine material outflow channel 29.

[0039] Understandably, when it is necessary to clean up fine materials, the second rotating shaft 225 can be rotated intermittently, causing the second rotating shaft 225 to drive the rotating drum 223 to rotate. When the rotating drum 223 rotates to the fine material outflow channel 29, the second notch 222 and the first notch 224, the fine materials can fall down. The rotating drum 223 continues to rotate, causing the fine materials to fall into the fine material collection box 22. The fine materials and water in the fine material collection box 22 can be cleaned by opening the cleaning door 221.

[0040] Furthermore, the synchronization mechanism includes a bearing seat 262 disposed on the water tank 20, a third rotating shaft 261 disposed on the bearing seat 262, a first synchronization structure 25 connecting the first rotating shaft 281 and the third rotating shaft 261, and a second synchronization structure 26 connecting the third rotating shaft 261 and the second rotating shaft 225; the first synchronization structure 25 includes a first pulley 251 disposed on the first rotating shaft 281, a second pulley 253 disposed on the second rotating shaft 225, and a belt structure 252 connecting the first pulley 251 and the second pulley 253; the second synchronization structure 26 includes a first bevel gear 264 disposed on the second rotating shaft 225 and a second bevel gear 263 disposed on the third rotating shaft 261, wherein the first bevel gear 264 and the second bevel gear 263 are meshed together.

[0041] Understandably, when the first rotating shaft 281 rotates, it will drive the third rotating shaft 261 to rotate through the first synchronous structure 25. The rotation of the third rotating shaft 261 will then drive the second rotating shaft 225 to rotate through the second synchronous structure 26, which in turn will drive the rotating drum 223 to rotate. The stroke can be set so that the first rotating shaft 281 drives the horizontal rod 283 to rotate one revolution, and the second rotating shaft 225 also drives the rotating drum 223 to rotate one revolution. When the bristles 284 on the horizontal rod 283 carry the fine material into the fine material outflow channel 29, the first notch 224 coincides with the fine material outflow channel 29.

[0042] Furthermore, the water storage mechanism includes a water tank 10 and a submersible pump 11 disposed in the water tank 10, and one end of the water outlet pipe 12 is connected to the submersible pump 11; the stirring mechanism includes a stirring tank 40 and a water scale 41 disposed in the stirring tank 40, the outlet of the water inlet pipe 23 is located directly above the water scale 41, and the water inlet pipe 23 is provided with a fine metering drain 42 and a coarse metering drain 43 near the water scale 41.

[0043] Understandably, water is pumped to the mixing tank by the submersible pump 11. Since the mixing tank is located at a high position, it can be pressurized by a booster pump. After the water is filtered in the mixing tank, it will fall onto the water scale 41 by gravity for weighing. If the weight is correct, the water will be sent into the mixing tank 40. Before the water scale 41 is weighed, the water can be pre-measured through the fine metering drain 42 or the coarse metering drain 43 as needed to make the result more accurate.

[0044] In summary, the water supply system for the mixing plant in the above embodiments of this utility model makes the flow meter measurement more accurate, the amount of clean water more accurate, thereby improving the strength of concrete, and can simultaneously clean coarse and fine materials.
