DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-Figure 4 , a sampling and extraction device suitable for chemical raw materials, comprising:

[0025] A sampling box 1, a suction box 11 is installed in the sampling box 1, and a sampling pump 12 is arranged above the sampling box 1;

[0026] Among them, the sampling pump 12 is connected to the inside of the suction box 11 through the suction pipe. In actual use, the raw materials in the suction box 11 are extracted through the sampling pump 12 and the suction pipe, and the raw materials are discharged to the designated position through a separately arranged discharge pipe, and the raw materials are tested to ensure the sampling and testing work.

[0027] The rotary sampling mechanism 2 is used to extract samples in all directions in the sampling box 1, including a rotating ring 21 that is sealed and rotatably installed on the sampling box 1, a sampling chamber 22 is arranged below the rotating ring 21, an annular sampling cavity 23 is sealed and rotatably installed on the peripheral side wall of the suction box 11, the annular sampling cavity 23 is connected with the interior of the sampling chamber 22 through a sample delivery channel 24, a motor 25 is arranged on the outer wall of the sampling box 1, a first gear 26 is arranged on the output end of the motor 25, a first gear ring 27 is arranged on the peripheral side wall of the rotating ring 21, and the first gear 26 and the first gear ring 27 are meshed with each other.

[0028] The annular sampling cavity 23 installed on the peripheral wall of the suction box 11 is sealed and rotatably mounted to ensure that the sample delivery channel 24 and the sampling chamber 22 can rotate, thereby ensuring the operation of the rotary sampling mechanism 2.

[0029] In view of the problem that the prior art cannot extract samples from the sample tank from different directions, resulting in the sampling of raw materials is still not comprehensive enough and the detection accuracy of the samples cannot be further improved, the utility model sets a rotating sampling mechanism 2. When sampling, the first gear 26 is driven to rotate by the motor 25, and the rotating ring 21 is further driven to rotate by the first gear ring 27, so that the sampling chamber 22 below the rotating ring 21 can perform a circular motion. When the sampling pump 12 extracts the raw material, the raw material in the sampling box 1 is extracted into the sample delivery channel 24 through the sampling chamber 22, and the raw material is further passed through the annular sampling cavity 23 into the suction box 11, and the raw material in the sampling box 1 is extracted from different directions, and the raw materials at different positions in the sampling box 1 are sampled more comprehensively, thereby improving the subsequent detection accuracy of the sample.

[0030] In addition, the sample delivery channel 24 is connected to the sampling chamber 22 through the bellows 4, so as to ensure that the sampling chamber 22 can perform reciprocating vertical displacement, thereby ensuring the subsequent operation of the vertical sampling mechanism 3.

[0031] The vertical sampling mechanism 3 is used to extract samples at various heights in the sampling box 1, including a reciprocating screw 31 rotatably installed below the rotating ring 21, a lifting sleeve 32 is threadedly connected to the reciprocating screw 31, and the sampling chamber 22 is fixedly installed on the lifting sleeve 32 through two connecting rods 33. A second gear 34 is provided on the top of the reciprocating screw 31, and a second gear ring 35 is fixedly installed inside the sampling box 1, and the second gear 34 and the second gear ring 35 are meshed with each other.

[0032] Among them, a limiting arc piece 5 is installed under the rotating ring 21, and the lifting sleeve 32 is slidably installed on the limiting arc piece 5. The lifting sleeve 32 is limited by the limiting arc piece 5, so that when the reciprocating screw rod 31 rotates relative to the rotating ring 21, the lifting sleeve 32 can only perform vertical displacement.

[0033] It is worth mentioning that during the rotation of the rotating ring 21, the second gear 34 on the reciprocating screw 31 performs a circular motion along the second gear ring 35, and the reciprocating screw 31 further rotates relative to the rotating ring 21, so that the lifting sleeve 32 on the reciprocating screw 31 can perform a reciprocating vertical displacement, so that the sampling chamber 22 can perform a reciprocating vertical displacement while performing rotational sampling, and sample raw materials at different heights. Only one motor 25 is needed to realize sampling and detection of raw materials from different heights and different directions, which not only improves the detection accuracy but also saves the driving source and reduces the cost.

[0034] In addition, the bottom of the suction box 11 is fixed to the bottom wall of the sampling box 1 by a fixing rod. Since the suction box 11 is separated by the annular sampling cavity 23, the bottom of the suction box 11 needs to be fixed by a fixing rod.

[0035] The functional principle of the utility model can be explained through the following operation modes:

[0036] When in use, the motor 25 and the sampling pump 12 are turned on, the motor 25 drives the first gear 26 to rotate, and the first gear ring 27 further drives the rotating ring 21 to rotate, so that the sampling chamber 22 below the rotating ring 21 can perform a circular motion. When extracting, the raw material in the sampling box 1 is extracted into the sample delivery channel 24 through the sampling chamber 22, and the raw material is further passed through the annular sampling cavity 23 into the suction box 11, and the raw material in the suction box 11 is extracted through the sampling pump 12 and the liquid extraction pipe, and the raw material in the sampling box 1 is extracted from different directions;

[0037] During the rotation of the rotating ring 21, the second gear 34 on the reciprocating screw 31 performs a circular motion along the second gear ring 35, and the reciprocating screw 31 further rotates relative to the rotating ring 21, so that the lifting sleeve 32 on the reciprocating screw 31 can perform a reciprocating vertical displacement, so that the sampling chamber 22 can perform a reciprocating vertical displacement while performing rotational sampling, so as to sample raw materials at different heights.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
