Description

Technical Field

[0001] This utility model relates to the field of solid powder production technology, specifically to a simple solid powder sampling device. Background Technology

[0002] For some organic pigment products, their appearance is usually as a solid powder. In the production process, after the material has undergone processes such as drying and grinding, samples need to be taken for quality analysis to determine whether the product meets the standards and to guide subsequent formula adjustments and production decisions.

[0003] Currently, the standard sampling procedure is as follows: After being processed by drying and grinding equipment, the material enters the dust collector through a pneumatic conveying pipeline and is finally unloaded into the storage silo below. During sampling, the operator needs to open the sampling hole at the top of the storage silo, fix the sampling spoon to the end of a long stick, reach into the silo by hand to scoop up the material, and then slowly pull it out, bag and seal it.

[0004] However, in the practical application of this sampling method, there are several obvious defects that seriously affect sampling efficiency, operational safety, and environmental hygiene:

[0005] (1) The unloading process must be interrupted: In order to avoid generating a lot of dust during the sampling process, causing material loss and environmental pollution, the unloading must be suspended every time a sample is taken, which seriously affects the continuity and efficiency of production;

[0006] (2) There is a risk of losing the sampling tool: The sampling spoon is simply tied to a long stick, which is easy to loosen or fall off when operating deep into the hopper, causing the tool to fall into the hopper, which not only contaminates the entire batch of materials, but also requires stopping the machine for cleaning, increasing the production risk;

[0007] (3) Operation relies on manpower and is labor-intensive: The entire process requires manual sticks to probe, scoop and retrieve, which requires high physical strength from the operators, and long-term repetitive operation can easily lead to fatigue and affect the representativeness of the sampling.

[0008] (4) Severe spillage of materials: When the sampling spoon and long stick are pulled out of the chamber, a large amount of powder is often attached to them, which is easy to spill around the sampling port. This not only wastes materials, but also pollutes the working environment, increases the cleaning burden and the risk of cross-contamination.

[0009] In summary, existing sampling methods are not only inefficient and unreliable, but also pose a potential threat to the production environment and sampling quality to some extent. Utility Model Content

[0010] The purpose of this invention is to provide a simple solid powder sampling device to solve the problems in the prior art. This sampling device avoids the need to interrupt the unloading operation in the traditional method, improves sampling efficiency and production continuity, and operates in a closed space, which greatly reduces the risk of dust and external pollution.

[0011] To solve the above problems, this utility model provides the following technical solution:

[0012] A simple solid powder sampling device includes a transverse transfer tube, the inner end of which is connected to a feed tube and the outer end of which forms a closed end. A sampling connector for installing a sampling device is provided at the bottom wall of the transverse transfer tube. An operating rod is inserted into the closed end and the two form a guiding fit. A receiving container is installed at one end of the operating rod located inside the transverse transfer tube. The receiving container moves back and forth between the cavity of the transverse transfer tube and the sampling connector by the guiding action of the operating rod relative to the closed end.

[0013] As a further embodiment of this utility model: a first limiting block is provided on one end of the operating lever located inside the transverse transfer pipe, so that when the receiving container moves above the sampling connector, the first limiting block is used to abut against the inner side of the closed end on the transverse transfer pipe.

[0014] As a further embodiment of this utility model: a second limiting block is provided on one end of the operating lever outside the transverse transfer pipe, so that when the receiving container is inserted into the feed pipe, the second limiting block is used to abut against the outer side of the closed end on the transverse transfer pipe.

[0015] As a further embodiment of this utility model: the sampling device also includes a baffle plate that is movably hinged to the inside of the feed pipe, and the hinged end is located above the connection between the transverse transfer pipe and the feed pipe, so that the baffle plate is arranged vertically and blocks the connection between the transverse transfer pipe and the feed pipe; and when the receiving container moves from the transverse transfer pipe to the feed pipe, the baffle plate can be pushed open by the receiving container.

[0016] As a further embodiment of this utility model: a sealing ring is provided on the side of the baffle plate facing the connection between the transverse transfer pipe and the feed pipe, and the shape of the sealing ring is adapted to the structure of the connection.

[0017] As a further embodiment of this utility model: the sampling device is a collection bag, which is detachably installed at the bottom of the sampling connector.

[0018] As a further embodiment of this utility model, a cleaning port is provided at the top wall of the transverse transfer pipe.

[0019] As a further embodiment of this utility model: a handle is installed on one end of the operating lever located outside the transverse adapter tube.

[0020] As a further embodiment of this invention, the closed end is configured as a plug.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. This simple solid powder sampling device, through its transverse transfer pipe design connected to the feed pipe, enables direct sampling during material conveying, avoiding the need to interrupt unloading as in traditional methods, thus improving sampling efficiency and production continuity. Simultaneously, a movable operating lever allows the receiving container to flexibly switch between the transverse transfer pipe and the sampling connector, enabling rapid, targeted sampling. This operation is conducted within a confined space, significantly reducing the risk of dust generation and external pollution.

[0023] 2. By setting a first limiting block at the inner end of the operating lever and cooperating with the closed end of the transverse transfer pipe, it is ensured that the receiving container can be accurately moved to the top of the sampling connector, thus improving the accuracy and consistency of the sampling position.

[0024] 3. The second limiting block at the outer end of the operating lever abuts against the outer side of the closed end, effectively limiting the material receiving container from extending excessively into the feed pipe, preventing equipment interference and material blockage, while enhancing the controllability and safety of the operation process and avoiding risks caused by human error.

[0025] 4. The cleaning port at the top of the horizontal transfer pipe facilitates daily inspection and maintenance of the pipe interior, effectively preventing material accumulation and blockage, extending the service life of the device, and improving the maintainability and ease of operation of the system.

[0026] 5. The hinged design of the baffle plate is cleverly located above the connection between the transverse transfer pipe and the feed pipe. When not sampling, it automatically closes the connection port vertically to prevent materials from accidentally entering the transverse transfer pipe. When sampling, it can be opened by the receiving container, realizing the automatic opening and closing function, ensuring that materials only pass through when sampling, and further improving the sealing and automation of the system.

[0034] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0035] Under normal circumstances, the top of the silo is equipped with several sets of feed pipes a, and the feed pipes a are opened and closed by the discharge rotary valve b. Based on this design, the following two embodiments are provided for sampling when the feed pipes a are conveying solid materials into the silo.

[0036] Example 1:

[0037] like Figures 1-2 As shown, a simple solid powder sampling device includes a transverse transfer tube 1 connected to a feed pipe a. A sampling connector 2 is located on the bottom side of the transverse transfer tube 1. A closed end 101 is sealed at the end of the transverse transfer tube 1 away from the feed pipe a. An operating rod 3 is movably inserted into the closed end 101. The two ends of the operating rod 3 are located inside and outside the transverse transfer tube 1, forming an inner end and an outer end, respectively. A handle 9 is provided on the outer end, and a receiving container 4 is fixedly provided on the inner end. Under normal circumstances, the receiving container 4 is located inside the transverse transfer tube 1. This state can be adjusted by... Figure 1 This is used for representation. Preferably, the closed end 101 can be directly selected as a plug.

[0038] When sampling is required, the operator manipulates the outer end to insert the receiving container 4 into the feed pipe a, ensuring the opening of the receiving container 4 faces upwards. This allows the fixed material to fall into the receiving container 4. This state can be achieved by... Figure 2The outer end is then pulled back, which moves the receiving container 4 into the horizontal transfer pipe 1 until it is above the sampling connector 2. Then, the operator drives the outer end to rotate, causing the receiving container 4 to rotate and invert, so that the solid material in the receiving container 4 falls into the sampling connector 2 below, thus achieving sampling.

[0039] Since the receiving container 4 is located inside the feed pipe a or the transverse transfer pipe 1, the operator cannot constantly observe its position. Therefore, during sampling, it cannot be guaranteed that the receiving container 4 is accurately positioned above the sampling connector 2. To address this, this embodiment has a first limiting block 5 fixedly installed on the inner end of the operating rod 3. When the receiving container 4 moves above the sampling connector 2, the first limiting block 5 abuts against the inner side of the closed end 101 on the transverse transfer pipe 1, alerting the operator that the receiving container 4 has moved into position. Similarly, during sampling, it cannot be guaranteed that the receiving container 4 will accurately extend into the feed pipe a. Therefore, this embodiment has a second limiting block 6 fixedly installed on the outer end of the operating rod 3. When the receiving container 4 extends into the feed pipe a, the second limiting block 6 abuts against the outer side of the closed end 101 on the transverse transfer pipe 1, alerting the operator that the receiving container 4 has moved into position.

[0040] In summary, by setting up the first limiting block 5 and the second limiting block 6, when either of them comes into contact with the closed end 101, the operator can use the sensation of contact to know the corresponding situation of the receiving container 4, ensuring the consistency of each receiving and discharging operation. Furthermore, the position of the second limiting block 6 on the operating lever 3 allows the operator to quickly determine the opening orientation of the receiving container 4.

[0041] Furthermore, a sampling device 7 can be detachably installed at the sampling connector 2, allowing for direct sealing and temporary storage after solid material is collected. Preferably, the sampling device 7 can be configured as a collection bag.

[0042] When the connection between the feed pipe a and the transverse transfer pipe 1 is exposed, some solid material may splash into the transverse transfer pipe 1 during the falling process, or spill into the transverse transfer pipe 1 during the sampling and re-extraction process. To address this, this embodiment also provides a cleaning port 8 on the top side of the transverse transfer pipe 1, which allows for periodic cleaning and maintenance of the interior of the transverse transfer pipe 1.

[0043] Example 2:

[0044] In the case where the connection between the aforementioned feed pipe a and the transverse transfer pipe 1 is exposed, this embodiment adds a set of baffle plates 10 to the first embodiment to seal the exposed connection. Figures 3-5 As shown, one end of the baffle plate 10 is movably hinged inside the feed pipe a, and the hinged end is located above the connection between the transverse adapter pipe 1 and the feed pipe a.

[0045] Under normal circumstances, the baffle plate 10 is arranged vertically and blocks the connection between the transverse transfer pipe 1 and the feed pipe a. This state can be achieved by... Figure 3 This is indicated by the following: When sampling, the receiving container 4 can be driven into the feed pipe a, the connection between the transverse adapter 1 and the feed pipe a will be opened, and the baffle 10 will be pushed by the receiving container 4 to rotate around its hinge point until the bottom of the baffle 10 rotates to the top position of the opening of the receiving container 4 and opens a portion of the opening, indicating that it has moved into place. This movement into place can be coordinated by the aforementioned second limiting block 6. At this time, the solid material falling from the feed pipe a and the solid material sliding on the baffle 10 will enter the receiving container 4 through the aforementioned partial opening, realizing material reception. This material reception state can be determined by... Figure 4 The direction of the solid material falling into the feed pipe a and the direction of the solid material sliding on the baffle plate 10 can be represented by vertical and oblique arrows, respectively. During the receiving process, in order to avoid the accumulation of solid material at the receiving position, the outer end of the operating rod 3 can be repeatedly pulled back and forth to make the fixed material in the receiving container 4 spread out flat inside. After collecting for a period of time or a certain amount, the outer end is pulled back to make the receiving container 4 move into the transverse transfer pipe 1 until the receiving container 4 moves above the sampling connector 2. Then the receiving container 4 completely releases the baffle plate 10 and pushes it to the left. The baffle plate 10 returns to its vertical position by its own weight, and seals the connection between the transverse transfer pipe 1 and the feed pipe a again to prevent some material from splashing into the transverse transfer pipe 1 during the falling process.

[0046] Furthermore, in order to improve the airtightness of the connection between the transverse transfer pipe 1 and the feed pipe a when the baffle plate 10 is arranged vertically, this embodiment provides a sealing ring (not shown in the figure) on the side of the baffle plate 10 facing the connection between the transverse transfer pipe 1 and the feed pipe a, and the shape of the sealing ring is adapted to the structure of the connection, that is, the sealing ring will fully surround and seal the outside of the connection.

[0047] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
