Specific Embodiments

[0024] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0025] Refer to Figures 1 - 5 and the present utility model provides a technical solution:

[0026] Embodiment:

[0027] AsFigures 1 - 5 As shown in the figure, a powder cement metering device includes a bracket 1 and at least one raw material metering barrel 2. A weighing member 3 for weighing the raw material metering barrel 2 is provided on the bracket 1. A lapping ear 4 is provided on the raw material aggregate barrel, and the raw material metering barrel 2 is supported on the weighing member 3 through the lapping ear 4;

[0028] As Figure 1 shown in the figure, a feed inlet is provided at the top of the raw material metering barrel 2, a discharge outlet is provided at the bottom of the raw material metering barrel 2, and a valve 5 is provided at the discharge outlet.

[0029] Among them, 1. The weighed raw materials are finally sent into a mixing tank 12 for mixing. 2. Liquids (such as water and hydrogen peroxide involved in the raw materials) can also be metered in the same way. The difference from the metering of solid powders is that after the solid powders are metered, they need to be (with power) transported through a conveying pipe (the conveying pipe is prior art) into the mixing tank 12; while for liquids, due to their good fluidity, only the raw material metering barrel 2 for liquid metering needs to be set higher than the mixing tank 12, and then the discharge outlet of the raw material metering barrel 2 is directly communicated with the mixing tank 12. 3. A storage tank 13 for storing raw materials is separately provided at the front end of the metering device of the present application. The discharge outlet of the storage tank 13 is vertically aligned (without contact between the two, and a gap of 1 mm - 6 mm can be reserved between them) with the feed inlet of the raw material metering barrel 2 through a feeding mechanism (which can be but is not limited to the same as the following conveying pipe) to supply materials to the raw material metering barrel 2.

[0030] Working principle: The raw materials (fast-drying cement) enter the raw material metering barrel 2 from the feed inlet of the raw material metering barrel 2. As the raw materials increase, the overall weight of the raw material metering barrel 2 increases.

[0031] During this process, the reading of the weighing member 3 changes (increases). When the reading of the weighing sensor increases to the set reading, the raw material feeding reaches the specified weight. At this time, (manually controlled or through setting a controller) the feeding mechanism is controlled to stop feeding.

[0032] After the feeding mechanism stops, the valve 5 at the bottom of the raw material metering barrel 2 is opened to discharge the raw materials from the raw material metering barrel 2 (the raw materials discharged from the raw material metering barrel 2 are sent into the mixing tank 12). When all the raw materials are discharged, the feeding mechanism starts to repeat the above actions.

[0033] The utility model can realize automatic weighing and metering of raw materials and discharging, can realize cyclic metering of raw materials, and improves the raw material distribution efficiency while ensuring the feeding accuracy of raw materials.

[0034] Furthermore, as Figure 1 and Figure 4As shown, a buffer bucket 6 is provided on the bracket 1. The buffer bucket 6 is located at the bottom of the discharge port, and a feed pipe corresponding to the discharge port is provided on the buffer bucket 6 (a gap is provided between the discharge port and the feed pipe to prevent the contact between the two from affecting the weighing of the load-bearing member).

[0035] When weighing multiple raw materials simultaneously, multiple raw material metering buckets 2 (three in this embodiment) are arranged on the bracket 1, and the discharge ports of the multiple raw material metering buckets 2 are respectively corresponding to the feed pipes up and down. The buffer bucket 6 can temporarily store multiple weighed raw materials and convey the multiple raw materials to the mixing bucket at one time. The conveying pipe does not need to be configured for each raw material metering bucket 2, improving the utilization rate of the device.

[0036] Further, as Figures 1 - 3 shown, the weighing member 3 is a weighing sensor. A rectangular frame 14 is provided at the top of the bracket 1, and triangular plates 7 are respectively provided at the four corners of the rectangular frame 14. The weighing member 3 is provided on the four triangular plates 7;

[0037] Four latching ears 4 are provided and the four latching ears 4 are evenly distributed outside the raw material metering bucket 2. The four latching ears 4 are arranged corresponding to the four weighing members 3 up and down. The valve 5 is a pneumatic wafer butterfly valve. Among them, the four latching ears 4 press on the weighing member 3, the raw material metering bucket 2 is supported by the four weighing members 3, and at the same time the bottom of the raw material metering bucket 2 is suspended; when feeding, the reading of the weighing sensor changes to achieve weighing.

[0038] The model of the weighing sensor is SQB100; the model of the pneumatic wafer butterfly valve is D671X-16, and it is equipped with an AT actuator with a model of DN200.

[0039] Further, as Figure 4 shown, an inclined feeding pipe 8 is provided at the bottom of the buffer bucket 6. The feeding pipe 8 is provided with a feeding inlet and a feeding outlet. The feeding inlet is communicated with the bottom of the buffer bucket 6, the feeding outlet extends upward to be communicated with the feeding port of the mixing bucket, and a mixer and a speed reducer for driving the feeding are provided at the feeding port end of the feeding pipe 8. The model of the feeding pipe 8 is a 219-type conveying pipe. The specific feeding principle is the prior art and will not be elaborated here.

[0040] One end of the feeding pipe 8 away from the buffer bucket 6 is communicated with one channel of a three-way joint 9, and feeding pipes 10 are respectively connected to the other two channels of the three-way joint 9, and a valve 5 is provided between the feeding pipe 10 and the three-way joint 9.

[0041] The three-way joint 9 is connected to the feeding pipe 8 through a flange.

[0042] The buffer bucket 6 is connected to the bracket 1 through an acute-angle plate 11. Among them, for convenient disassembly, the acute-angle plate 11 is connected to the bracket 1 through bolts.

[0043] When in use, this device is used for metering liquid raw materials and solid raw materials respectively. After the raw material metering is completed, it is directly transported to the mixing tank. After being evenly mixed by the mixing tank, pouring can be carried out; it can ensure that the raw material ratio of each pouring is consistent, and the raw materials are mechanically distributed with high distribution efficiency.

[0044] The above are only the preferred embodiments of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the concept described herein through the above teachings or the technology or knowledge in related fields. And the changes and modifications made by those skilled in the art without departing from the spirit and scope of the present invention should all be within the protection scope of the appended claims of the present invention.
