Detailed Description

The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by a person skilled in the art without any inventive effort, are intended to be within the scope of the present utility model, based on the embodiments of the present utility model.

Referring to fig. 1-5, the present utility model provides a technical solution:

Examples:

As shown in fig. 1-5, a powder cement metering device comprises a bracket 1 and at least one raw material metering barrel 2, wherein a weighing piece 3 for weighing the raw material metering barrel 2 is arranged on the bracket 1, a lap joint lug 4 is arranged on a raw material collecting barrel, and the raw material metering barrel 2 is supported on the weighing piece 3 through the lap joint lug 4;

As shown in fig. 1, a feed inlet is formed in the top of the raw material metering barrel 2, a discharge outlet is formed in the bottom of the raw material metering barrel 2, and a valve 5 is arranged at the discharge outlet.

Wherein, the raw materials after 1 and weighing are finally sent into a stirring tank 12 for mixing. 2. The liquid (such as water and hydrogen peroxide involved in raw materials) can be metered in the same way, and is different from the metering of solid powder in that a conveying pipe (with power) (the conveying pipe is in the prior art) is required to be sent into the stirring tank 12 after the metering of the solid powder, and the liquid has good fluidity, so that the raw material metering barrel 2 for metering the liquid is only required to be arranged higher than the stirring tank 12, and then the discharge port of the raw material metering barrel 2 is directly communicated with the stirring tank 12. 3. The front end of the metering device is separately provided with a storage tank 13 for containing raw materials, and a discharge hole of the storage tank 13 is aligned up and down (not contacted with a gap of 1mm-6mm reserved between the two) with a feed inlet of the raw material metering barrel 2 through a feeding mechanism (which can be the same as a conveying pipe described below, but not limited to), so as to feed the raw material metering barrel 2.

The working principle is that raw materials (quick-drying cement) enter the raw material metering barrel 2 from a feed inlet of the raw material metering barrel 2, and the whole weight of the raw material metering barrel 2 is increased along with the increase of the raw materials.

The process involves a change (increase) in the reading of the weighing element 3, and when the load cell reading increases to the set reading, the raw material feed reaches the specified weight, at which point (manually controlled or by a set controller) the feed mechanism is controlled to stop feeding.

After the feeding mechanism is stopped, the valve 5 at the bottom of the raw material metering tank 2 is opened to discharge the raw material from the raw material metering tank 2 (the raw material discharged from the raw material metering tank 2 is fed into the agitation tank 12). When the raw materials are all discharged, the feeding mechanism is started to repeat the previous actions.

Further, as shown in fig. 1 and fig. 4, the support 1 is provided with a buffer bucket 6, the buffer bucket 6 is located at the bottom of the discharge hole, and the buffer bucket 6 is provided with a feeding pipe corresponding to the discharge hole (a gap is formed between the discharge hole and the feeding pipe to prevent the load-bearing member from being weighed when the discharge hole and the feeding pipe are contacted).

When weighing multiple raw materials simultaneously, set up a plurality of raw materials measurement barrels 2 (three in this embodiment) on the support 1, the discharge gate of a plurality of raw materials measurement barrels 2 corresponds from top to bottom with the inlet pipe respectively. The buffer barrel 6 can temporarily store various weighed raw materials and convey the various raw materials to the stirring barrel, and the conveying pipe does not need to be matched with each raw material metering barrel 2, so that the utilization rate of the device is improved.

Further, as shown in fig. 1-3, the weighing piece 3 is a weighing sensor, a rectangular frame 14 is arranged at the top of the bracket 1, triangular plates 7 are respectively arranged at four corners of the rectangular frame 14, and the weighing pieces 3 are arranged on the four triangular plates 7;

The four overlapping lugs 4 are pressed on the weighing pieces 3, the raw material metering barrel 2 is supported by the four weighing pieces 3, meanwhile, the bottom of the raw material metering barrel 2 is suspended, and when feeding is carried out, the reading of the weighing sensor changes, so that weighing is realized.

The weighing sensor is of the type SQB100, the pneumatic butt-clamp butterfly valve is of the type D671X-16, and the pneumatic butt-clamp butterfly valve is matched with an AT actuator of the type DN 200.

Further, as shown in fig. 4, an inclined material conveying pipe 8 is arranged at the bottom of the buffer tank 6. Wherein conveying pipeline 8 is equipped with conveying feed inlet and conveying discharge gate, and conveying feed inlet and buffer memory bucket 6 bottom intercommunication, and conveying discharge gate upwards extends to the feed inlet intercommunication with the agitator, is equipped with agitator and the speed reducer that are used for driving the pay-off on the feed inlet end of conveying pipeline 8, and conveying pipeline 8 model is 219 conveyer pipe, and specific conveying principle is prior art, and details are not made here.
