[0025] See also Figure 1-4 The utility model provides a technical solution: a sampling device for the production of heavy calcium carbonate, comprising a sampling box 1, wherein an installation box 1 2 and an installation box 2 3 are detachably installed between two adjacent side walls of the sampling box 1, and a sampling tube 4 and a sampling bottle 5 or an auxiliary component 13 are detachably installed between two other adjacent side walls of the sampling box 1, the installation box 1 2 and the sampling bottle 5 or the auxiliary component 13 are arranged opposite to each other, and the installation box 2 3 and the sampling tube 4 are arranged opposite to each other, and passage openings 10 are opened on the side walls of the sampling box 1 and at the positions of the installation box 1 2, the installation box 2 3, the sampling tube 4, the sampling bottle 5 or the auxiliary component 13, a cleaning component 8 is installed in the installation box 1 2, a sampling component 9 is installed in the installation box 2 3, and a filter cover 11 is fixedly provided on the inner side wall of the sampling box 1 near the installation box 2 3 and at the passage opening 10.

[0026] Specifically, the left side and bottom of the sampling box 1 are fixed with threaded tubes 6 at the position of the channel opening 10, and the sampling tube 4, sampling bottle 5 or auxiliary component 13 are all screwed on the corresponding threaded tubes 6 for easy disassembly.

[0027] Accessories can be replaced at the position of the sampling bottle 5. When the sampling bottle 5 is installed, powder sampling can be performed; when the auxiliary component 13 is installed, the interior of the sampling device can be quickly cleaned, reducing the steps of disassembling the sampler for cleaning.

[0028] The operator inserts the inlet of the sampling tube 4 into the heavy calcium carbonate powder to be sampled, starts the sampling component 9 to absorb the powder, and the powder enters the sampling box 1 along the sampling tube 4 and falls into the sampling bottle 5 under the obstruction of the filter cover 11, completing the sampling. Then the operator spirally removes the sampling bottle 5, installs the auxiliary component 13 in the position of the original sampling bottle 5, starts the cleaning component 8 to blow out strong wind, and blows the inner wall of the sampling box 1 and the sampling tube 4 to quickly remove the powder adhering to the inside to facilitate the next sampling and improve the sampling efficiency.

[0029] Furthermore, the space inside the installation box 2 and the space inside the sampling box 1 are connected through the channel opening 10. The cleaning component 8 includes an air outlet pump 81, which is installed on the inner wall of the installation box 2. Several air vents 82 are opened on the outer wall of the installation box 2.

[0030] Specifically, when the inner wall of the sampling box 1 needs to be cleaned, the air outlet pump 81 is started to blow air into the internal space of the sampling box 1. When the sampling bottle 5 is removed, the air can be used to clean the powder adhering to the filter cover 11; when the auxiliary component 13 is installed, the inner wall of the sampling tube 4 can be cleaned.

[0031] Furthermore, a through groove 14 and a through hole 15 are respectively opened on the left and right side walls of the installation box 2 near the sampling box 1, and elastic cotton 16 is bonded to the upper and lower side walls of the through hole 15. An insert plate 17 is inserted between the two pieces of elastic cotton 16, and the insert plate 17 is inserted in the through groove 14.

[0032] Specifically, the arrangement of the insert plate 17 seals the inner space of the installation box 2 , so that when the powder is sampled by the sampling assembly 9 , the powder is prevented from entering the inner space of the installation box 2 through the passage opening 10 .

[0033] Furthermore, the space inside the installation box 2 3 and the space inside the sampling box 1 are connected through the channel port 10. The sampling component 9 includes an air pump 91. The air pump 91 is installed on the inner wall of the installation box 2 3, and the air suction port of the air pump 91 extends into the filter cover 11. Several air vents 2 92 are provided on the outer wall of the installation box 2 3.

[0034] Specifically, a handle column 7 is fixed to the bottom of the installation box 2 3, which is convenient for the operator to hold the sampling device; an inclined block 12 is fixed to the inner wall of the sampling box 1 near the sampling bottle 5, so that after the powder enters the sampling box 1, it can enter the sampling bottle 5 along the inclined block 12, which is convenient for collection.

[0035] Furthermore, the auxiliary component 13 includes a threaded column 131 , and an air guide block 133 is fixedly connected to the straight side wall of the threaded column 131 extending into the sampling box 1 , and a connecting plate 132 is fixedly connected to the other straight side wall of the threaded column 131 .

[0036] Specifically, the threaded column 131 can be spirally connected to the threaded tube 6 opposite the installation box 2, so that the air guide block 133 extends into the sampling box 1. When the auxiliary air pump 81 blows air, the air can be blown out from the sampling tube 4 to clean the inner wall of the sampling tube 4.

[0037] The working principle and use process of the present invention are as follows: After the present invention is installed, in the initial state, the sampling bottle 5 is screwed into the threaded tube 6 opposite the installation box 2. The operator holds the handle column 7 and inserts the inlet of the sampling tube 4 into the powder to be sampled. The vacuum pump 91 is turned on to create a negative pressure environment in the sampling box 1. The powder flows into the sampling box 1 along the sampling tube 4 and enters the sampling bottle 5 under the obstruction of the filter cover 11, completing the sampling of the powder.

[0038] When it is necessary to perform secondary sampling of different positions of the powder, first remove the sampled sampling bottle 5 by spiral means, pull out the plug plate 17, start the air outlet pump 81 to blow out strong air, and clean the sampling box 1 and the filter cover 11 with air. Then, install the auxiliary component 13 at the position of the original sampling bottle 5, with the curved wall of the air guide block 133 facing the sampling tube 4. Start the air outlet pump 81 again, so that strong air is blown out from the sampling tube 4 under the guidance of the air guide block 133 to clean the inner wall of the sampling tube 4.

[0039] Finally, the auxiliary component 13 is removed and replaced with a new sampling bottle 5. The interior of the sampling device can be cleaned without disassembling the sampling device to avoid mixing of powders during multiple samplings and reduce sampling accuracy.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
