Description

Technical Field

[0001] This utility model relates to the field of calcium carbonate, and in particular to a calcium carbonate dry powder dehydration device. Background Technology

[0002] Calcium carbonate (CaCO3) is an inorganic compound, commonly known as limestone, stone powder, marble, etc. Calcium carbonate is neutral, slightly soluble in water, and soluble in hydrochloric acid. It is mainly found in rocks such as aragonite, calcite, chalk, limestone, marble, and travertine, and is also a major component of animal bones or shells. Calcium carbonate powder production requires dehydration; however, existing dehydration devices, with their dehydration tanks embedded in the outer shell, make removing the dry powder time-consuming and laborious, necessitating improvement. Utility Model Content

[0003] The purpose of this invention is to provide a calcium carbonate dry powder dehydration device to solve the problem that it is time-consuming and laborious to remove the dry powder because the dehydration barrel of the existing calcium carbonate dry powder dehydration device is embedded in the outer shell.

[0004] To address the aforementioned problems, this utility model provides a calcium carbonate dry powder dehydration device, comprising an outer cylinder and a dehydration barrel. The dehydration barrel is detachably and rotatably installed inside the outer cylinder. Multiple dehydration holes are provided on the side wall of the dehydration barrel. The outer cylinder includes a lower rigid cylinder and an upper flexible folding cylinder. A filter baffle is fixedly installed inside the lower rigid cylinder, and multiple filter holes are provided on the filter baffle. The cavity below the filter baffle is a drainage chamber. A waterproof sleeve is fixedly installed at the center of the filter baffle, and a motor is fixedly installed inside the waterproof sleeve. A mounting plate is fixedly installed at the output end of the motor. The dehydration barrel is detachably installed on the mounting plate. When the upper flexible folding cylinder is stretched, its top wall is higher than the top wall of the dehydration barrel. When the upper flexible folding cylinder is folded, its top wall is lower than the bottom wall of the dehydration barrel.

[0005] The calcium carbonate dry powder dehydration device provided by this utility model also has the following technical features:

[0006] Furthermore, a conical drainage sleeve is coaxially fixed on the waterproof diaphragm, and the bottom wall of the conical drainage sleeve is fixedly connected to the top wall of the filter diaphragm.

[0007] Furthermore, a drain pipe is fixedly provided on one side of the drain cavity.

[0008] Furthermore, the waterproof sleeve is made of rubber.

[0009] Furthermore, the upper flexible folding tube is made of tetrafluoroethylene.

[0010] Furthermore, the mounting plate is bolted to the bottom wall of the dehydration tank.

[0011] This invention has the following beneficial effects: Before dehydration, an appropriate amount of calcium carbonate powder is first poured into the dehydration barrel. Then, the upper flexible folding cylinder is stretched upward. Then, the motor is started, and the motor drives the dehydration barrel to rotate for centrifugal dehydration. The upper flexible folding cylinder can block the water thrown out from the dehydration hole to prevent water droplets from splashing. The thrown water enters the drain chamber after being filtered by the filter plate. After dehydration, the upper flexible folding cylinder is pressed to fold it, making it easy to disassemble the dehydration barrel and quickly pour out the dry calcium carbonate powder.

[0014] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0015] like Figures 1 to 2 In the embodiment of the calcium carbonate dry powder dehydration device of the present invention shown, an outer cylinder 1 and a dehydration barrel 2 are included. The dehydration barrel 2 is detachably and rotatably installed inside the outer cylinder 1. The side wall of the dehydration barrel 2 is provided with a plurality of dehydration holes 20. The outer cylinder 1 includes a lower rigid cylinder 10 and an upper flexible folding cylinder 11. A filter baffle 3 is fixedly installed inside the lower rigid cylinder 10. A plurality of filter holes 30 are provided on the filter baffle 3. The cavity below the filter baffle 3 is a drainage cavity 301. A waterproof sleeve 31 is fixedly installed at the center of the filter baffle 3. A motor 4 is fixedly installed inside the waterproof sleeve 31. An installation plate 41 is fixedly installed at the output end of the motor 4. The dehydration barrel 2 is detachably installed on the installation plate 41. When the upper flexible folding cylinder 11 is stretched... The top wall of the upper flexible folding cylinder 11 is higher than the top wall of the dehydration tank 2. After the upper flexible folding cylinder 11 is folded, the top wall of the upper flexible folding cylinder 11 is lower than the bottom wall of the dehydration tank 2. Specifically, before dehydration, an appropriate amount of calcium carbonate powder is poured into the dehydration tank 2. Then, the upper flexible folding cylinder 11 is stretched upward. Then, the motor 4 is started. The motor 4 drives the dehydration tank 2 to rotate for centrifugal dehydration. The upper flexible folding cylinder 11 can block the water thrown out from the dehydration hole 20 to prevent water droplets from splashing. The thrown water enters the drain chamber 301 after being filtered by the filter baffle 3. After dehydration, the upper flexible folding cylinder 11 is pressed to fold it, so that the dehydration tank 2 can be disassembled and the calcium carbonate dry powder can be poured out quickly.

[0016] In one embodiment of this application, a conical drainage sleeve 310 is coaxially fixed on the waterproof septum 31. The bottom wall of the conical drainage sleeve 310 is fixedly connected to the top wall of the filter septum 3. Specifically, the conical drainage sleeve 310 can prevent water from converging at the root of the waterproof septum 31, so that the water can be quickly discharged from the filter hole 30.
