Description

Technical Field

[0001] This utility model relates to the field of concrete technology, specifically to an admixture dispensing device. Background Technology

[0002] During the concrete mixing process in concrete mixer trucks, the addition of admixtures is a crucial step in ensuring concrete quality. Workers typically carry dedicated admixture containers, wear necessary protective equipment, check the remaining quantity and quality of the admixtures, and then bring them to the side of the mixer truck. When adding the admixtures, the mixing system is started to keep the concrete in a mixing state, ensuring that the admixtures are evenly dispersed during the mixing process. Workers will slowly pour the admixtures into the feeding port of the mixing tank through a connecting hose or a dedicated filling pipe to avoid splashing and clogging. During the filling process, it is necessary to continuously observe the flow rate and status of the admixture, adjust the valve opening, control the filling speed, and ensure that the addition amount meets the design requirements. After filling, close the valve, clean the connecting pipes and admixture tank to prevent residue contamination or misuse. However, because the concrete mixer truck's feeding port is high, workers need to use ladders or other auxiliary tools to reach the feeding port for operation. This not only increases the difficulty of the operation but also poses certain safety hazards. Workers must be careful during the climbing process to avoid slipping or falling, especially in wet or unstable environments where the risks are more prominent. In addition, carrying the admixture tank to a high place for filling is also difficult. The admixture tank is usually heavy, which can easily cause fatigue during carrying and may even lead to accidents such as tipping or leakage due to improper operation. Utility Model Content

Detailed Implementation

[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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] Please see Figure 1-5 The present invention provides an embodiment of an admixture dispensing device, comprising a housing 1 with four casters at the bottom, a storage tank 5 for storing admixtures installed inside the housing 1, a pump pipe assembly 6 installed on one side of the outer wall of the storage tank 5, and a corrugated telescopic pipe 7 installed at the outlet end of the pump pipe assembly 6. The top end of the corrugated telescopic pipe 7 extends upward and penetrates to the outside of the housing 1. The storage tank 5 ensures that the admixture does not leak or deteriorate during storage, thus ensuring operational safety and material quality.

[0019] An L-shaped nozzle 4 is installed at the top of the corrugated telescopic tube 7. A vertical frame 2 is installed on one side of the top of the housing 1. A linear lifting module 3 for driving the L-shaped nozzle 4 to lift and lower the Z-axis is installed on the inner wall of one side of the vertical frame 2. A control panel 8 that is electrically connected to the input end of the pump liquid pipe group 6 is installed on the outer wall of one side of the vertical frame 2.

[0020] The casters are installed at the corners of the bottom of the chassis 1. One side of the caster is fitted with an external threaded foot at the bottom of the chassis 1. The casters at the bottom of the chassis 1 can rotate freely in all directions, allowing the device to move and be positioned easily in space.

[0021] The pump-liquid pipe assembly 6 includes a centrifugal pump 602 installed inside the casing 1 on one side, a right-angle drain pipe 601 installed on the inlet end of the centrifugal pump 602, and a switch valve 603 installed on the outlet end of the centrifugal pump 602. The upper end of the switch valve 603 is connected to the lower end of the corrugated expansion pipe 7. The corrugated expansion pipe 7 can adapt to the movement, vibration and thermal expansion and contraction of the device or pipeline, and prevent the pipeline from cracking or being damaged due to excessive stress.

[0022] One end of the right-angle drain pipe 601 extends into the interior of the storage tank 5. An inlet pipe 501 is installed at one edge of the top of the storage tank 5. When the pump pipe assembly 6 is working, the operator turns on the centrifugal pump 602 through the control panel 8 and opens the switch valve 603. At this time, the centrifugal pump 602 sends the admixture in the storage tank 5 into the corrugated telescopic pipe 7 and the L-shaped spray pipe 4 through the right-angle drain pipe 601 and the switch valve 603, and then pumps it into the concrete mixer truck through the L-shaped spray pipe 4.

[0023] A liquid outlet pipe 902 is installed at the center of the bottom of the liquid storage tank 5. A second switch valve 903 is installed at one end of the liquid outlet pipe 902. A three-way pipe 9 is installed at the end of the second switch valve 903 away from the liquid outlet pipe 902. A third switch valve 904 is installed at the lower end of the three-way pipe 9. A bypass pipe 901 is installed at the upper end of the three-way pipe 9. One end of the bypass pipe 901 extends into the interior of the liquid storage tank 5. The liquid storage tank 5 is made of stainless steel components.

[0024] When discharging the additive in the storage tank 5, the operator can open the bypass pipe 901 and the second switch valve 903 to form a passage between the outlet pipe 902, the three-way pipe 9, and the third switch valve 904, thereby quickly discharging the additive in the storage tank 5.

[0025] In this embodiment, during use, the operator first uses the casters to move the chassis 1 to one side of the concrete mixer truck, ensuring the chassis 1 and the storage tank 5 are stable and preventing shaking or tipping during filling. The pump pipe assembly 6 is then connected, linking the outlet of the storage tank 5 to the inlet of the pump pipe assembly 6, ensuring a tight, leak-free connection. The other end of the pump pipe assembly 6 is connected to the corrugated expansion pipe 7. The flexibility of the corrugated expansion pipe 7 allows for adjustment of the delivery path during operation, reducing pipeline stress. The operator then operates the screw linear lifting module 3 to adjust the height of the L-shaped nozzle 4 until the discharge port of the L-shaped nozzle 4 enters the... The concrete mixer truck's inlet is positioned optimally, allowing the L-shaped nozzle 4 to facilitate admixture spraying while preventing uneven spraying or splashing. Careful observation of the device's status is crucial during this process to ensure smooth lifting and lowering, avoiding sudden vibrations or jamming. Once the L-shaped nozzle 4 is positioned correctly, the pump-liquid assembly 6 is activated via the control panel 8. This assembly transports the admixture from the storage tank 5 to the corrugated expansion pipe 7 and the L-shaped nozzle 4, thus delivering the admixture into the concrete mixer truck. After filling, the pump-liquid assembly 6 is shut off to stop admixture delivery, and the machine box 1 is moved until the L-shaped nozzle 4 is removed from the concrete mixer truck.
