Description

Technical Field

[0001] This utility model relates to the field of calcium oxide processing technology, specifically a quantitative sampling device for calcium oxide processing. Background Technology

[0002] Calcium oxide is an inorganic compound, commonly known as quicklime. Its physical properties include a white powder on the surface, which may appear grayish-white when impure, and pale yellow or gray when containing impurities. It is hygroscopic.

[0003] A search revealed a Chinese patent document disclosing a quantitative sampling device for calcium oxide processing [Announcement No.: CN221377093U]. This device includes a processing pipe with a fixed frame on its surface. A sealing tube is located inside the fixed frame, with its bottom passing through the fixed frame and extending to the bottom of the fixed frame. The surface of the sealing tube is in close contact with the interior of the processing pipe. An extraction mechanism is located at the top of the sealing tube. The extraction mechanism includes a pull ring, a connecting plate, a first sealing gasket, and a connecting rod. The bottom of the pull ring is fixedly connected to the top of the connecting plate, and the bottom of the connecting plate is in close contact with the top of the sealing tube. This device solves the problem that most existing quantitative sampling devices for calcium oxide processing sample at the calcium oxide storage site, which may cause direct contact between the calcium oxide and carbon dioxide in the air, thus affecting the processing quality of the calcium oxide.

[0004] During the processing of calcium oxide, testing is required. This is usually done by manual sampling, which is time-consuming and labor-intensive. Calcium oxide can easily corrode workers, and errors can easily occur during the sampling process, leading to inaccurate sampling. To address this problem, we propose a quantitative sampling device for calcium oxide processing. Utility Model Content

[0005] The purpose of this invention is to provide a quantitative sampling device for calcium oxide processing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a quantitative sampling device for calcium oxide processing, comprising a conveyor belt, a support frame fixedly installed on the top of the conveyor belt, a sampling cylinder disposed inside the support frame, a scale fixedly disposed on the surface of the sampling cylinder, and a quantitative mechanism disposed inside the sampling cylinder; The quantitative mechanism includes a piston plate disposed inside the sampling cylinder, a pressure plate fixedly connected to the top of the piston plate, a threaded rod fixedly connected to the top of the pressure plate, a threaded hole for cooperating with the threaded rod being opened at the top of the sampling cylinder, and a screwing block fixedly connected to the top of the threaded rod. A transmission mechanism is fixedly mounted on a support frame and is capable of controlling the sampling cylinder to move up and down. A sealing mechanism is fixedly installed on one side of the sampling cylinder.

[0007] Preferably, the transmission mechanism includes a motor fixedly installed on the top of the support frame, the output end of the motor extending through to the bottom of the support frame and fixedly connected to a lead screw, a transmission block being drivenly connected to the surface of the lead screw, and one side of the transmission block being fixedly connected to one side of the sampling cylinder.

[0008] Preferably, the sealing mechanism includes a support block fixedly connected to one side of the sampling cylinder, a motor fixedly connected to the top of the support block, the output end of the motor extending through to the bottom of the support block and fixedly connected to a connecting block, and a baffle fixedly connected to one side of the connecting block.

[0009] Preferably, a rubber pad is fixedly connected to the top of the baffle, and the diameter of the rubber pad is larger than the diameter of the sampling cylinder.

[0010] Preferably, a positioning block is provided on one side of the support frame, and a bearing is provided on the top of the positioning block, which is rotatably connected to the bottom of the lead screw through the bearing.

[0011] Preferably, a sliding block is fixedly connected to one side of the transmission block, and a sliding groove is provided on the inner wall of the support frame to cooperate with the sliding block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting a quantitative mechanism, can drive the screwing block to rotate inside the threaded hole by rotating the screwing block. The screwing block will gradually move downward, and at the same time drive the pressure plate and piston plate to move downward until the piston plate is at the corresponding scale mark position and stops. Then, the sampling cylinder is controlled to move downward by the transmission mechanism, and calcium oxide will enter the sampling cylinder to achieve the function of quantitative sampling. 2. By setting up a transmission mechanism, this utility model can start the motor, which will drive the lead screw to rotate. During the rotation of the lead screw, the transmission block will drive the sampling cylinder to move up and down. When the sampling cylinder moves downward, calcium oxide will enter the sampling cylinder. Then, under the drive of the transmission block, the sampling cylinder will move upward to complete the sampling process. No manual sampling is required, which improves the sampling rate. 3. By setting a sealing mechanism, this utility model can start the motor after the sampling tube moves downward and completes the sampling. The motor will drive the connecting block and the baffle to rotate 180°, so that the baffle blocks the bottom position of the sampling tube. At this time, when the transmission mechanism controls the sampling tube to rise, calcium oxide will not fall from the bottom of the sampling tube, thereby improving the sampling accuracy.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 - Figure 5 As shown, Example 1: A quantitative sampling device for calcium oxide processing includes a conveyor belt 1, characterized in that: a support frame 2 is fixedly installed on the top of the conveyor belt 1, a sampling cylinder 3 is provided inside the support frame 2, a scale mark 4 is fixedly provided on the surface of the sampling cylinder 3, and a quantitative mechanism is provided inside the sampling cylinder 3. The quantitative mechanism includes a piston plate 5 disposed inside the sampling cylinder 3, a pressure plate 6 fixedly connected to the top of the piston plate 5, a threaded rod 7 fixedly connected to the top of the pressure plate 6, a threaded hole 8 for cooperating with the threaded rod 7 opened at the top of the sampling cylinder 3, and a screwing block 9 fixedly connected to the top of the threaded rod 7. The transmission mechanism is fixedly mounted on the support frame 2 and can control the sampling cylinder 3 to move up and down. A sealing mechanism is fixedly installed on one side of the sampling cylinder 3.

[0017] In this embodiment, considering that testing is required during the calcium oxide processing, which is usually done manually, sampling is time-consuming and labor-intensive. Calcium oxide can easily corrode workers, and errors can easily occur during sampling, leading to inaccurate sampling. Therefore, a quantitative mechanism is set up. By rotating the screw block 9, the screw block 9 will drive the threaded rod 7 to rotate inside the threaded hole 8. The threaded rod 7 will gradually move downward, driving the pressure plate 6 and piston plate 5 downward at the same time, until the piston plate 5 stops at the corresponding scale mark 4. Then, the sampling cylinder 3 is controlled to move downward through the transmission mechanism, and calcium oxide will enter the sampling cylinder 3, realizing the function of quantitative sampling. It should be noted that the sampling cylinder 3 is made of transparent acrylic, and the positions of structures such as the piston plate 5 can be seen from the outside.

[0018] The transmission mechanism includes a motor 10 fixedly installed on the top of the support frame 2. The output end of the motor 10 extends through to the bottom of the support frame 2 and is fixedly connected to a lead screw 11. A transmission block 12 is connected to the surface of the lead screw 11. One side of the transmission block 12 is fixedly connected to one side of the sampling cylinder 3.

[0019] In this embodiment, by setting a transmission mechanism, the motor 10 can be started, and the motor 10 will drive the lead screw 11 to rotate. During the rotation of the lead screw 11, the transmission block 12 will drive the sampling cylinder 3 to move up and down reciprocally. When the sampling cylinder 3 moves downward, calcium oxide will enter the sampling cylinder 3. Then, under the drive of the transmission block 12, the sampling cylinder 3 will move upward to complete the sampling process. There is no need for manual sampling, which improves the sampling rate.

[0020] A positioning block 18 is provided on one side of the support frame 2, and a bearing 19 is provided on the top of the positioning block 18, and is rotatably connected to the bottom of the lead screw 11 through the bearing 19.

[0021] In this embodiment, by setting the positioning block 18 and the bearing 19, the lead screw 11 can play a supporting role, while improving its smoothness and stability during rotation.

[0022] A sliding block 20 is fixedly connected to one side of the transmission block 12, and a sliding groove 21 that cooperates with the sliding block 20 is opened on the inner wall of the support frame 2.

[0023] In this embodiment, by setting the sliding block 20 and the sliding groove 21, when the lead screw 11 drives the transmission block 12, it can be restricted to move up and down along the trajectory of the sliding groove 21, thus limiting the movement trajectory.

[0024] Example 2: Based on Embodiment 1, this embodiment only controls the up-and-down movement of the sampling cylinder 3 through a transmission mechanism to achieve the function of sampling calcium oxide. However, considering that calcium oxide is in powder form and is easily dropped from the sampling cylinder 3 due to gravity, affecting the accuracy of sampling, the sealing mechanism in this application includes a support block 13 fixedly connected to one side of the sampling cylinder 3. A motor 14 is fixedly connected to the top of the support block 13, and the output end of the motor 14 extends through to the bottom of the support block 13 and is fixedly connected to a connecting block 15. A baffle 16 is fixedly connected to one side of the connecting block 15.

[0025] In this embodiment, by setting a sealing mechanism, after the sampling cylinder 3 has moved downwards and completed sampling, the motor 14 is started. The motor 14 will drive the connecting block 15 and the baffle 16 to rotate 180°, so that the baffle 16 blocks the bottom position of the sampling cylinder 3. Figure 5 As shown, when the transmission mechanism controls the sampling cylinder 3 to rise, calcium oxide will not fall from the bottom of the sampling cylinder 3, thereby improving the sampling accuracy.

[0026] A rubber pad 17 is fixedly connected to the top of the baffle 16. The diameter of the rubber pad 17 is larger than the diameter of the sampling cylinder 3.

[0027] In this embodiment, by setting a rubber pad 17, when the baffle 16 moves to the bottom of the sampling cylinder 3, the rubber pad 17 will also move synchronously to the bottom of the sampling cylinder 3, thereby improving the sealing effect.

[0028] Working principle: The user rotates the screwing block 9, which drives the threaded rod 7 to rotate inside the threaded hole 8. The threaded rod 7 will gradually move downward, and at the same time drive the pressure plate 6 and piston plate 5 to move downward until the piston plate 5 is at the corresponding scale mark 4. Then, by starting the motor 10, the motor 10 will drive the lead screw 11 to rotate. During the rotation of the lead screw 11, the transmission block 12 will drive the sampling cylinder 3 to move up and down reciprocally. When the sampling cylinder 3 moves downward, calcium oxide will enter the sampling cylinder 3. Then, driven by the transmission block 12, the sampling cylinder 3 will move upward to complete the sampling process. There is no need for manual sampling, which improves the sampling rate. After the sampling cylinder 3 has moved downwards and completed sampling, the motor 14 is started. The motor 14 will drive the connecting block 15 and the baffle 16 to rotate 180°, so that the baffle 16 blocks the bottom of the sampling cylinder 3. Figure 5 As shown, when the transmission mechanism controls the sampling cylinder 3 to rise, calcium oxide will not fall from the bottom of the sampling cylinder 3, thereby improving the sampling accuracy.

[0029] It should be noted that the motor 10 and the motor 14 are existing devices or equipment in the prior art, or devices or equipment that can be implemented in the prior art, and the specific composition and principle of the power supply of the motor 10 and the motor 14 are clear to those skilled in the art, so they will not be described in detail here.
