Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, specifically a lime block sampling device. Background Technology

[0002] Lime blocks (particle size 3-50mm) are an important auxiliary material in the metallurgical process, and their quality is extremely important, especially the calcium oxide content, which must meet the requirements. Therefore, incoming inspection of lime blocks is crucial, and the key to this inspection is sampling.

[0003] When lime blocks arrive at the factory, they are unloaded into the unloading shed using dump trucks. The unloading shed area is cramped, and the unloading process generates a great deal of dust. To accurately inspect the quality of the entire truckload of lime blocks, during the unloading process of each dump truck, sampling personnel use shovels to crawl into the confined area behind the truck and collect samples at three different time points: before, during, and after the unloading. These three samples are then mixed together to create a test sample for analyzing the lime block quality. However, manual sampling is labor-intensive, takes place in harsh environments, and it is difficult to accurately control the three time points, often resulting in the risk of taking samples twice in the middle but failing to collect a sample in the third time. Utility Model Content

[0004] The purpose of this invention is to provide a lime block sampling device to solve the problems in the background art where it is difficult to control the three time periods of manual sampling and the sampling environment is harsh and harmful to the human body.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A lime block sampling device, comprising:

[0007] The sample chamber has an open top and a sealed bottom, and a partition is installed inside the sample chamber to divide the interior of the sample chamber into at least three sampling spaces;

[0008] The cover is detachably fastened to the top of the sample chamber. The gap between the partition and the cover is smaller than the particle size of the lime block. The cover has a sample inlet hole, which corresponds to a sampling space. Each sample inlet hole is provided with a chamber door. When each chamber door is opened, the corresponding sample inlet hole is opened. When closed, the corresponding sample inlet hole is blocked.

[0009] The opening and closing mechanism includes a control compartment and an electrical control system. The control compartment is located at the bottom of the sample compartment, and the electrical control system is located in the control compartment and connected to each of the compartment doors to control the doors to open sequentially according to a preset time interval. This design completely solves the problems of the tipping process of dump trucks, where manually dividing the process into three stages (front, middle, and rear) is difficult to control, and the work environment is characterized by heavy dust and poor conditions, posing significant health risks.

[0010] Furthermore, the electronic control system includes a power supply, a timer controller, and electromagnets. The number of timer controllers and electromagnets corresponds to the number of bin doors. Both the power supply and the timer controllers are located inside the control bin. The power supply powers the timer controllers, and the electromagnets are fixed to the inner surface of their respective bin doors. Each timer controller is electrically connected to one of the electromagnets. When the electromagnet controlled by the timer controller is energized, it attracts the cover, and the bin door closes. When the electromagnet controlled by the timer controller is de-energized, it disconnects, and the bin door opens. Through this setup, the timer controller pre-sets the time, de-energizing the electromagnets during the required material retrieval period, thus automatically opening the bin door for sampling.

[0011] Furthermore, one side of the compartment door is connected to the cover via a hinge, and the electromagnet is fixed to the inner surface of the compartment door. When the compartment door is closed, a portion of the electromagnet contacts the cover. With this configuration, when the electromagnet is energized, it adheres to the cover, completely covering the sample inlet, preventing limestone from entering the sampling space. When the electromagnet is de-energized, it and the compartment door fall into the sampling space, completely exposing the sample inlet, allowing the limestone to fill the sampling space and completing the sampling.

[0012] Furthermore, a recess is provided on the side of the compartment door away from the hinge, and a protrusion is provided on the cover to mate with the recess. The electromagnet is positioned close to the recess so that when the compartment door is closed, the electromagnet contacts the protrusion on the cover through the recess. This arrangement increases the contact area between the electromagnet and the cover, improving the adsorption stability between them.

[0013] Furthermore, the cover is conical in shape, and its bottom surface is detachably connected to the top of the sample chamber. The conical surface of the cover has sample inlet holes corresponding to the sampling spaces. This design allows limestone to slide down the conical surface of the cover, facilitating sampling.

[0014] Furthermore, the apex angle of the cover is 30° to 60°. This design facilitates the sliding of limestone.

[0015] Furthermore, it also includes a first clamp; the top of the sample chamber and the cover are detachably connected by the first clamp.

[0016] Furthermore, it also includes a second clamp; the bottom end of the control compartment has a detachable base plate, which is detachably connected to the periphery of the control compartment via the second clamp.

[0017] Furthermore, the number of partitions is three, and the three partitions are evenly distributed to divide the interior of the sample chamber into three sampling spaces of equal area.

[0018] Furthermore, the number of partitions is four, and the four partitions are evenly distributed to divide the interior of the sample chamber into four sampling spaces of equal area.

[0019] Furthermore, it also includes handles, which are located on both sides of the sample compartment. This arrangement facilitates the movement of the device.

[0020] Furthermore, the height of the control chamber is ≥100mm. This setting ensures that the sample chamber has a certain height above the ground, facilitating sampling.

[0021] This invention has the following advantages over the prior art:

[0022] 1. This utility model discloses a lime block sampling device, comprising a sample chamber, a cover, and an opening and closing mechanism. The sample chamber is divided into at least three sampling spaces by a partition. The cover is fastened to the top of the sample chamber, and the cover has sampling holes corresponding to the sampling spaces. Each sampling hole is equipped with a chamber door. The opening and closing mechanism includes a control chamber and an electrical control system inside the control chamber. The electrical control system is connected to the chamber door and is used to control the chamber door to open sequentially according to a preset time interval. In this utility model, the gap between the partition and the cover is smaller than the particle size of the lime block, preventing lime blocks from entering other sampling spaces along the gap after one sampling space is filled, thus preventing the sampling volume in subsequent time intervals from meeting the sampling requirements. By controlling the chamber door to open sequentially according to the preset time interval through the electrical control system, the problem of manual material collection, which involves dividing the material into three sections (front, middle, and rear) is difficult to control, and the site is dusty and harmful to human health is completely solved.

Therefore, they should not be construed as limitations on this utility model.

[0031] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be further discussed and described in the description of the subsequent figures.

[0033] Example 1:

[0034] Currently, lime blocks are sampled manually with a hand-held shovel during the dumping process by a dump truck. However, manually dividing the sample into three sections (front, middle, and back) is difficult to control, and the site is extremely dusty, resulting in a very poor working environment. Therefore, if... Figures 1 to 5 As shown, this utility model provides a lime block sampling device, including: a sample chamber 1, a cover 4, and an opening and closing mechanism; the sample chamber 1 is open at the top and sealed at the bottom, and a partition 2 is provided inside the sample chamber 1 to divide the interior of the sample chamber 1 into at least three sampling spaces 3 (four sampling spaces in this embodiment); the cover 4 is detachably fastened to the top of the sample chamber 1, the gap between the partition 2 and the cover 4 is smaller than the particle size of the lime block, and the cover 4 has a sampling hole, which corresponds one-to-one with the sampling space 3; each sampling hole is provided with a door 5, which opens the corresponding sampling hole when it is open and blocks the corresponding sampling hole when it is closed; the opening and closing mechanism includes a control chamber 6 and an electrical control system; the control chamber 6 is located at the bottom of the sample chamber 1, and the electrical control system is located in the control chamber 6 and connected to each of the doors 5 to control each of the doors 5 to open sequentially according to a preset time interval.

[0035] The particle size of typical lime blocks is approximately 3-50mm. By setting the gap between the partition and the cover to be smaller than the particle size of the lime blocks, the sampling spaces can be separated. This prevents lime blocks from entering other sampling spaces along the gap after one sampling space is filled, thus avoiding insufficient sampling volume in subsequent time intervals. A sealing gasket can also be placed on the upper surface of the partition 2 to minimize the gap between the partition 2 and the cover 4. The lime block sampling device provided by this utility model can completely replace manual sampling, completely solving the problems of difficulty in controlling the three stages of sampling (front, middle, and rear), and the poor working environment with heavy dust, which is harmful to the human body.

[0036] Specifically, sample chamber 1 and control chamber 6 are arranged vertically, separated by a shelf 15. Shelf 15 serves as both the base of sample chamber 1 and the cover of control chamber 6. The shelf 15 is welded and sealed to the inner wall of sample chamber 1 to prevent limestone contamination and damage to the electrical control system. The height of the control chamber is ≥100mm. In this embodiment, the height of the control chamber is 200mm, which facilitates the installation of the electrical control system while also providing sample chamber 1 with a certain height above the ground for easy sampling.

[0037] In this embodiment, the electronic control system includes a power supply 7 (battery), a timer controller 8 (a common delay switch), and an electromagnet 9. The number of timer controllers 8 and the number of electromagnets 9 correspond to the number of compartment doors 5, meaning there is a one-to-one correspondence between the timer controllers 8, electromagnets 9, and compartment doors 5. The power supply 7 and the timer controllers 8 are both located within the control compartment 6. Figure 4 As shown, the timer controller 8 and power supply 7 can be directly fixed to the shelf 15. The power supply 7 is used to power the timer controller 8. The electromagnet 9 is fixed to the inner surface of the corresponding compartment door 5. The timer controller 8 and the electromagnet 9 are electrically connected one-to-one. When the electromagnet 9 controlled by the timer controller 8 is energized, the electromagnet 9 is attracted to the cover 4, and the compartment door 5 is closed. When the electromagnet 9 controlled by the timer controller 8 is de-energized, the electromagnet 9 is de-energized, and the compartment door 5 is opened. Specifically, the electromagnet's attraction force is 40kg, which is sufficient to meet the compartment door closing requirement. The electromagnet 9 is always attracted to the cover 4 before the timer controller is de-energized, keeping the compartment door closed. When the timer controller 8 is de-energized, the electromagnet 9 loses its attraction force, and the compartment door opens.

[0038] like Figures 3-5 As shown, the warehouse doors are controlled by a timer controller 8 to delay their opening. The entire unloading process takes a maximum of 30 minutes, with the timer controller 8 (delay switch) set to open one warehouse door every 8 minutes. Samples can be obtained at least in the early, middle, and late stages of the unloading process, meeting the sampling requirements.

[0039] For example, if the vehicle unloading time is between 20 and 30 minutes, in this embodiment, sample chamber 1 is divided into four sampling spaces 3 by partitions 2. The power-off time of each electromagnet is set to 8 minutes, 16 minutes, 24 minutes, and 30 minutes by a timer controller 8. The last sampling space may not be able to collect any material, but the samples obtained in the first three time periods have already met the sampling requirements.

[0040] like Figure 1 and Figure 4 As shown, one side of the door 5 is connected to the cover 4 via a hinge 10. The electromagnet 9 is fixed to the inner surface of the door 5. When the door 5 is closed, a portion of the electromagnet 9 contacts the cover 4. When the electromagnet 9 is energized, it adheres to the cover 4, completely covering the sample inlet with the door 5. At this time, limestone cannot enter the sampling space 3. When the electromagnet 9 is de-energized, it and the door 5 fall into the sampling space 3 together, thus completely exposing the sample inlet. The limestone then fills the sampling space 3, completing the sampling.

[0041] Specifically, a recess 11 is provided on the side of the door 5 away from the hinge 10, and a protrusion 12 is provided on the cover 4 to mate with the recess 11. The electromagnet 9 is positioned near the edge of the recess 11 so that when the door 5 is closed, the electromagnet 9 contacts the protrusion 12 of the cover 4 through the recess 11. This arrangement increases the contact area between the electromagnet 9 and the cover 4, improving the adsorption stability between them. Figure 4 As shown, the bottom end of the compartment door 5 is connected to the cover 5 via a hinge 10. A recess 11 is formed at the top of the compartment door 5. An electromagnet 9 is fixed to the compartment door 5 along the edge of the recess 11. The portion of the electromagnet 9 extending beyond the recess 11 is used to attract the protrusion 12 on the cover 4, thereby increasing the contact area between the electromagnet and the cover 4. The electromagnet 9 is positioned away from the hinge 10 to improve the stability of the compartment door 5 when closed. When the electromagnet 9 is de-energized, the compartment door 5 and the electromagnet 9 completely fall into the sampling space, fully opening the sample inlet. This avoids the situation where the electromagnet 9 is located on either side of the compartment door and close to the hinge, as the position of the electromagnet and the compartment door would partially obstruct the sample inlet when the electromagnet is de-energized, affecting the sampling volume.

[0042] The cover 4 is conical in shape, and its bottom surface is detachably connected to the top of the sample chamber 1. The conical surface of the cover 4 has sample inlet holes corresponding one-to-one with the sampling spaces 3. The apex angle of the cover 4 is 30° to 60°, preferably 45°. By designing the conical apex, material jamming is less likely during lime pouring. Material receiving is convenient when the sampling door is open.

[0043] like Figure 1As shown, this embodiment also includes a first clamp 13 and a second clamp 14; the top of the sample chamber 1 is detachably connected to the cover 4 via the first clamp 13. The bottom of the control chamber 6 has a detachable base plate 15, which is detachably connected to the periphery of the control chamber 6 via the second clamp 14. Existing clamps can be used for the first clamp 13 and the second clamp 14. After sampling, the first clamp 13 is opened, the cover 4 is removed, and the sample in the sample chamber is poured out and mixed together for the next sample preparation step. The use of two clamps facilitates material discharge and subsequent maintenance of this sampling device.

[0044] In this embodiment, handles are also included, which are disposed on both sides of the sample compartment. This arrangement facilitates the movement of the device.

[0045] In practical use:

[0046] By setting four partitions, the interior of sample bin 1 is divided into four sampling spaces 3 of equal area. The cover 4 is designed as a cone with a 45° conical apex, which facilitates material discharge, reduces resistance, and allows material to enter easily when the bin door 5 is opened. The four bin doors 5 are independently controlled by four timer controllers 8, and the four sampling spaces 3 can achieve independent material receiving in four stages. The vehicle unloading time is between 20-30 minutes, and the timers of the four timer controllers 8 can be set to 8 minutes, 16 minutes, 24 minutes, and 30 minutes. At the corresponding time, the corresponding electromagnet 9 is de-energized by the timer controller 8, and the corresponding bin door 5 is opened for sampling. The above operation can completely fill at least three sampling spaces, meeting the sampling requirements. The sampling amount in each sampling space 3 is about 1 kg, and the sampling amount and sampling interval fully meet the sample preparation requirements for subsequent testing.

[0047] The device weighs 12kg, making it portable and ready for immediate use. Equipped with a 12V power supply, the four electromagnets exert a force of 40kg. Sample chamber 1 and control chamber 6 are separated and welded together by a shelf 15, ensuring complete independence and preventing limestone from entering control chamber 6 and damaging electrical components. Sample extraction is convenient; simply open the first clamp 13 and lift the cover to easily empty the samples from the four sampling chambers. Note that there is a wire connector socket between the electromagnets and the timer controller, located on the outside of the device; this socket must be disconnected before lifting the cover. In practice, the wires between the electromagnets and the timer controller, as well as the outside of the socket, are protected against limestone corrosion.

[0048] Example 2:

[0049] This embodiment is the same as embodiment 1 except for the following technical solutions:

[0050] In this embodiment, three partitions 2 are used, and the three partitions 2 are evenly distributed to divide the interior of the sample chamber 1 into three sampling spaces 3 of equal area. Three sample inlets, three chamber doors, and three timer controllers are also provided. During sampling, the three timer controllers 8 are set to 8 minutes, 16 minutes, and 24 minutes. Within the corresponding time, the corresponding electromagnet 9 is de-energized by the timer controller 8, and the corresponding chamber door 5 is opened for sampling. The above operation can completely fill the three sampling spaces, meeting the sampling requirements.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
