Abstract
Description
Technical Field
[0001] This utility model relates to the field of powder sampling technology, and in particular to a powder reagent sampling device. Background Technology
[0002] Chromium removal is a crucial step in cement production, aiming to reduce the chromium content in cement to meet environmental protection and other relevant requirements. During the transportation of chromium removal agents, sampling and testing of the agents are necessary. This testing ensures the quality of the chromium removal agents, guaranteeing their stability and reliability, and compliance with cement production quality standards and specifications.
[0003] In existing technologies, the sampling and transportation processes for chromium removal agents are carried out separately, which is cumbersome and requires two people to complete the sampling process, thus limiting the convenience of operation. Therefore, based on the above situation, it is necessary to design a powder reagent sampling device to solve the above problems. Utility Model Content
[0004] This invention provides a powder reagent sampling device to solve the problem of separating the sampling and transportation of chromium removal agents in the prior art, thereby improving the convenience of chromium removal agent sampling.
[0005] The technical problem solved by this utility model is achieved by the following technical solution:
[0006] A powder reagent sampling device includes a feeding cylinder and a sampling cylinder. The feeding cylinder is a cylindrical structure with openings at both ends. The input end of the feeding cylinder is used to receive materials. The bottom of the feeding cylinder is connected to a conveying cylinder. The bottom opening of the conveying cylinder is used to convey materials to a downstream conveying system. The sampling cylinder is inclinedly connected to one side of the conveying cylinder. A rotating rod is rotatably connected to the inner wall of the conveying cylinder near the sampling cylinder. One end of the rotating rod extends to the outside of the sampling cylinder. The rotating rod is provided with a switching flap for controlling the opening and closing of the sampling cylinder. When the switching flap rotates to abut against the inner wall of the conveying cylinder away from the sampling cylinder, the material in the conveying cylinder is discharged from the sampling cylinder.
[0007] Preferably, the upper end of the feeding cylinder is provided with a buffer cavity, the bottom of the feeding cylinder extends into the interior of the buffer cavity, and the cross-section of the buffer cavity is larger than the cross-section of the feeding cylinder.
[0008] Preferably, the switching flap is provided with a material blocking part at one end near the rotating rod, the material blocking part being used to prevent material from falling into the gap between the rotating rod and the inner wall of the feeding cylinder.
[0009] Preferably, the height of the switching flap is greater than the width of the feeding cylinder.
[0010] Preferably, the sampling cylinder is provided with a fixing plate, and the fixing plate has a slot for fixing the rotating rod.
[0011] Preferably, the outer edge of the switching flap is provided with an elastic frame.
[0012] The beneficial effects of this utility model are as follows: by setting a sampling cylinder on the feeding cylinder, the material falls into the feeding cylinder through the feeding cylinder. When it is necessary to sample the material, the rotating rod is rotated to make the switching flap rotate to the side of the feeding cylinder away from the sampling cylinder to block the feeding cylinder. The material that has fallen into the feeding cylinder will be discharged from the sampling cylinder, thereby realizing sampling. After the sampling is completed, the switching flap is rotated to the sampling cylinder to block the sampling cylinder, and the material can continue to be conveyed through the feeding cylinder. The material conveying and sampling processes can be freely switched, improving the convenience of sampling. Attached Figure Description

Detailed Implementation
[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0021] Reference Figures 1-5 As shown, a powder reagent sampling device includes a feeding cylinder 1, which is a cylindrical structure with openings at both ends. The input end of the feeding cylinder 1 receives material conveyed by a Roots blower. A feeding tube 2 is connected to the bottom of the feeding cylinder 1. The Roots blower creates a negative pressure environment inside the feeding cylinder 1 and the feeding tube 2, allowing the material to be conveyed more smoothly to the downstream conveying system through the bottom opening of the feeding tube 2. During material conveying, depending on the intended use of the material, such as a chromium removal agent, sampling and testing are required. Therefore, a sampling tube 3 is inclinedly connected to one side of the feeding cylinder 2. A rotating rod 4 is rotatably connected to the inner wall of the feeding cylinder 2 near the sampling tube 3. One end of the rotating rod 4 extends to the outside of the sampling tube 3. The rotating rod 4 is equipped with a switch for controlling the opening and closing of the sampling tube 3. When the switching flap 5 rotates to contact the inner wall of the feeding cylinder 2 away from the sampling cylinder 3, the material in the feeding cylinder 2 is discharged from the sampling cylinder 3. In use, the rotating rod 4 located outside the feeding cylinder 2 is lifted upwards. During the lifting process, the rotating rod 4 located inside the feeding cylinder 2 rotates, causing the switching flap 5 to rotate to contact the inner wall of the feeding cylinder 2 away from the sampling cylinder 3, thus sealing the sampling cylinder 3. The sampling cylinder 3 opens, and the material conveyed from the feeding cylinder 1 flows out from the inclined sampling cylinder 3, thereby completing the sampling. After the sampling is completed, the rotating rod 4 is released. Under the gravity of the rotating rod 4 located outside the feeding cylinder 2, the switching flap 5 returns to its original position to seal the sampling cylinder 3, and the feeding cylinder 2 opens to realize the material conveying. The process of freely switching between material conveying and sampling improves the convenience of sampling.
[0022] Reference Figures 1-5 As shown, the upper end of the feeding cylinder 2 is provided with a buffer cavity 6, and the bottom of the feeding cylinder 1 extends into the interior of the buffer cavity 6. The cross-section of the buffer cavity 6 is larger than the cross-section of the feeding cylinder 1. When the switching flap 5 blocks the feeding cylinder 2 and the sampling cylinder 3 is opened, the negative pressure between the feeding cylinder 1 and the feeding cylinder 2 changes. When the material in the feeding cylinder 1 enters the interior of the feeding cylinder 2, the larger buffer cavity 6 acts like a buffer pool. The larger buffer cavity 6 works in conjunction with the feeding cylinder 1 to help balance the pressure and can play a role in absorption, preventing the material from suddenly overflowing.
[0023] Reference Figure 4 As shown, further, the switching flap 5 is provided with a material blocking part 7 at one end near the rotating rod 4. When the switching flap 5 rotates to abut against the inner wall of the feeding cylinder 2 away from the sampling cylinder 3, there will be a certain gap between the rotating rod 4 and the inner wall of the feeding cylinder 2. When the material coming down from the feeding cylinder 1 comes out of the sampling cylinder 3 along the switching flap 5, the material blocking part 7 can block the gap between the rotating rod 4 and the inner wall of the feeding cylinder 2 to prevent the material from falling into the gap and affecting the rotation of the rotating rod 4.
[0024] Reference Figures 3-4 As shown, further, the height of the switching flap 5 is greater than the width of the feeding cylinder 2. When the switching flap 5 rotates to contact the inner wall of the feeding cylinder 2 away from the sampling cylinder 3, the switching flap 5 will tilt downward from the inner wall of the sampling cylinder 3 towards the sampling cylinder 3. In this state, the smoothness of material taking can be maintained.
[0025] The outer edge of the switching flap 5 is provided with an elastic frame 10, which can be made of rubber, silicone or other materials. When the switching flap 5 contacts the inner wall of the feeding cylinder 2, it can reduce the contact friction between the two and reduce the risk of mutual collision and wear.
[0026] Reference Figures 1-2 As shown, the sampling cylinder 3 is further provided with a fixing plate 8, and the fixing plate 8 is provided with a slot 9 for fixing the rotating rod 4. In the initial state of the switching flap 5 blocking the sampling cylinder 3, the rotating rod 4 located outside the feeding cylinder 2 is in a horizontal state. At this time, the rotating rod 4 can be inserted into the slot 9 to fix it, thereby preventing it from shaking and affecting the normal conveying process.
