Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, specifically a portable sampling device for chemical products. Background Technology

[0002] Chemical raw materials refer to the raw materials used in chemical industrial production. They can generally be divided into two categories: organic chemical raw materials and inorganic chemical raw materials. When chemical raw materials are transported to the processing site, a sampler is usually used to take out a portion of the raw materials for testing in order to determine whether the raw materials meet the standards.

[0003] Traditional sampling devices often use containers to sample chemical raw materials. However, this process requires staff to hold the sampling container and come into contact with the chemical raw materials. When sampling corrosive chemicals, if the chemical raw materials come into contact with the staff's hands, it can cause burns or even corrosion, posing a certain safety risk. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a portable sampling device for chemical products, which has the advantages of safe use and convenient sampling, and solves the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a portable sampling device for chemical products, including a sampling chamber, a sampling tube installed in the inner cavity of the sampling chamber, a floating tube movably sleeved on the outer wall of the sampling tube, a return spring fixedly mounted on the outer wall of the floating tube, a transport screw rotatably connected to the inner cavity of the sampling tube, a drive motor fixedly mounted in the inner cavity of the sampling chamber, a drive belt rotatably connected to the power output shaft of the drive motor, a discharge chamber opened in the inner cavity of the sampling chamber, a discharge port opened at the bottom of the sampling chamber, a support plate fixedly mounted at the bottom of the sampling chamber, a sampling cylinder installed on the top of the support plate, and a push rod fixedly mounted on the outer wall of the sampling chamber.

[0006] As a preferred technical solution of this utility model: the outer wall of the transport screw is in contact with the inner wall of the sampling tube, and the outer wall of the end of the drive belt away from the drive motor is in rolling connection with the outer wall of the transport screw.

[0008] As a preferred technical solution of this utility model: the outer wall of the sampling tube is provided with a discharge port, and the position of the discharge port corresponds to the outer wall of the discharge bin.

[0009] As a preferred technical solution of this utility model: the top of the sampling cylinder is in contact with the bottom of the discharge port, and the inner wall of the feeding hopper is inclined.

[0010] As a preferred technical solution of this utility model: the outer wall of the floating tube is provided with a moving groove, and the outer wall of the sampling tube is equipped with a fixing plate, and the shape of the outer wall of the fixing plate matches the shape of the inner wall of the moving groove.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This portable chemical product sampling device uses a conveyor screw installed in the inner cavity of the sampling tube. Driven by a motor, the conveyor screw rotates, causing the material to move upward under the action of the conveyor screw, thereby achieving material sampling. The material then enters the sampling cylinder through the feed hopper and discharge port, thus achieving material sampling. This also avoids workers coming into contact with the raw materials during the sampling process, improving the safety of equipment use.

[0013] 2. This portable chemical product sampling device uses a floating tube installed on the outer wall of the sampling tube. To perform sampling normally, the sampling tube must be pushed downwards, causing the floating tube to move upwards. After sampling is completed, the downward pushing of the sampling tube can be stopped, making the sampling operation of the device very convenient and more conducive to the use of materials. It can also separate the transport screw from the materials in a timely manner. Attached Figure Description

[0022] In the above structure, the conveying screw 5 is installed in the inner cavity of the sampling tube 2, and the drive motor 6 is installed in the inner cavity of the sampling chamber 1. The conveying screw 5 is driven by the drive motor 6, so that the material is extracted during the rotation of the conveying screw 5, and the material is extracted from the bottom of the sampling tube 2 and transported to the top of the sampling tube 2.

[0023] In a preferred embodiment: the outer wall of the transport screw 5 is in contact with the inner wall of the sampling tube 2, and the outer wall of the drive belt 7 at the end away from the drive motor 6 is in rolling connection with the outer wall of the transport screw 5.

[0024] In the above structure, the drive motor 6 installed in the inner cavity of the sampling chamber 1 and the drive belt 7 installed on the power output shaft of the drive motor 6 can drive the transport screw 5 under the drive of the drive motor 6, so that the material is transported upward from the inner cavity of the floating tube 3 and the sampling tube 2, and the material is moved from the bottom of the sampling tube 2 to the position of the unloading chamber 8.

[0025] In a preferred embodiment: the outer diameter of the sampling tube 2 matches the inner diameter of the floating tube 3, and the outer wall of the end of the return spring 4 away from the floating tube 3 is connected to the outer wall of the sampling tube 2.

[0026] In the above structure, by setting a reset spring 4 on the outer wall of the floating tube 3, when the floating tube 3 is placed in the material, the sampling tube 2 is pushed downward appropriately, so that the floating tube 3 moves upward along the outer wall of the sampling tube 2, thereby stretching the reset spring 4. When the downward pushing of the sampling tube 2 stops, the floating tube 3 will return to its original state under the action of the reset spring 4.

[0027] In a preferred embodiment, the outer wall of the sampling tube 2 is provided with a discharge port, and the position of the discharge port corresponds to the outer wall of the discharge bin 8.

[0028] In the above structure, the material can be lifted upward by the feeding port opened on the outer wall of the sampling tube 2, so that the material can enter the inner cavity of the feeding bin 8 from the feeding port opened on the outer wall of the sampling tube 2, and enter the inner cavity of the sampling cylinder 10 along the inner wall of the feeding bin 8, thereby realizing the sampling of the material.

[0029] In a preferred embodiment, the top of the sampling cylinder 10 is in contact with the bottom of the discharge port 9, and the inner wall of the discharge bin 8 is inclined.

[0030] In the above structure, by opening a feeding bin 8 in the inner cavity of the sampling bin 1, when the material is lifted upward by the action of the conveying screw 5, the material will enter the inner cavity of the feeding bin 8 from the inner cavity of the sampling tube 2, and move downward along the inner wall of the feeding bin 8, thereby entering the inner cavity of the sampling cylinder 10 from the discharge port 9, thereby realizing the sampling and collection of the material.

[0032] In the above structure, by using the moving groove opened on the outer wall of the floating tube 3 and the fixed plate installed on the outer wall of the sampling tube 2, when the sampling tube 2 is pushed downward, the floating tube 3 will move upward, thereby stretching the return spring 4, so that the bottom of the sampling tube 2 can better contact the chemical material, and then be lifted upward under the action of the transport screw 5.

[0033] Working principle: During the use of the above equipment, when it is necessary to sample some solid chemical raw materials, the bottom of the sampling tube 2 and the floating tube 3 are brought into contact with the top of the chemical material, and the sampling chamber 1 and the sampling tube 2 are pushed downward. At this time, the floating tube 3 will move upward along the outer wall of the sampling tube 2, so that the floating tube 3 retracts into the outer wall of the sampling tube 2, thereby causing the return spring 4 to be stretched upward, so that the bottom of the sampling tube 2 contacts the material. Then, the drive motor 6 is started, and the drive motor 6 drives the conveying screw 5 to rotate, thereby lifting the chemical raw material upward and moving it along the inner wall of the sampling tube 2. When the material moves to the discharge port opened on the outer wall of the sampling tube 2, it will enter the inner cavity of the discharge chamber 8 and move downward along the inner wall of the discharge chamber 8. Then, it enters the inner cavity of the sampling cylinder 10 through the discharge port 9, thereby completing the sampling of the chemical material.
