Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of diamond selection equipment, in particular to a particle sorting monitoring and protection device. Background Art
[0002] The sorting machine is mainly used for sorting superhard granular materials such as diamond. Taking the sorting of diamond particles as an example, its principle is to adjust the inclination angle and vibration frequency of the sorting disc, and use vibration and friction to sort the diamond according to the completeness of the crystal form. Diamond particles of the same crystal form fall into the same collection box for collection to achieve the purpose of sorting. It has the advantages of fast sorting speed and short time, and can improve production efficiency. The sorting discs of existing diamond sorting machines are basically exposed to the air. When screening tiny diamond particles, the air flow in the workshop will affect the screening results, resulting in large screening errors. However, diamond screening is a long-lasting operation process, especially when there are multiple sorting machines in a workshop, the staff will walk from time to time, loading and unloading materials, and observing whether the screening work of each sorting machine is proceeding normally. At this time, the movement of personnel drives the air flow to have a greater impact on the screening of tiny diamonds. In addition, the humidity of the air will also affect the screening of diamond particles. For example, if the air humidity is high, the diamond particles may adhere to each other, resulting in screening errors. Utility Model Content
[0003] The utility model aims to provide a particle sorting monitoring and protection device, which can monitor the air humidity during the particle sorting process, protect the particles from being affected by air flow during sorting, and reduce the error of particle sorting.
[0004] In order to achieve the above object, the utility model discloses a particle sorting monitoring and protection device, which comprises:
[0005] A protective cover at least covers the sorting plate of the sorting machine, and a ventilation window is provided on the protective cover;
[0006] An on-off mechanism is arranged near the ventilation window, and the on-off mechanism includes a driving component and a baffle, the baffle is adapted to the ventilation window, and the baffle and the wall of the ventilation window of the protective cover are in contact with each other, and the driving component drives the baffle to cover the ventilation window;
[0007] A hygrometer, disposed in the protective cover;
[0008] A fan, disposed in the protective cover;

[0010] Preferably, it also includes a monitoring element for monitoring the approach of a human body, and the monitoring element is connected to the controller.
[0011] Preferably, at least the wall of the protective cover facing the sorting disk of the selection machine is a convex lens structure.
[0012] Preferably, the on-off mechanism is arranged on the outside of the protective cover, and the fan is arranged opposite to the ventilation window.
[0013] Preferably, two ventilation windows are provided, and the ventilation windows are not higher than the sorting disk of the selection machine, and each ventilation window is equipped with an on-off mechanism.
[0014] Preferably, a breathable dustproof net is provided on the ventilation window.
[0015] Preferably, the protective cover is placed on a machine table of a selection machine, and a sealing sponge is provided on the bottom edge of the protective cover.
[0016] Preferably, a suction cup or a magnet for adsorbing the platform of the selection machine is provided at the bottom of the protection cover, or a plurality of blocks for limiting the displacement of the protection cover are provided on the platform of the selection machine.
[0017] Preferably, the protective cover is also provided with a loading door and a discharging door.
[0018] Preferably, a humidifier and / or a heater is further provided in the protective cover, and the humidifier and the heater are connected to a controller.
[0019] The utility model has the following beneficial effects:
[0020] 1. The utility model sets a protective cover, which at least covers the sorting disk of the selection machine, so that the sorting disk is relatively isolated from the outside air, and protects diamond, cubic boron nitride and other particles on the sorting disk from being affected by air flow, and the humidity in the protective cover can be relatively constant, which is conducive to sorting and reduces sorting errors. By setting a hygrometer to monitor the air humidity in the protective cover in real time, once the air humidity in the protective cover exceeds the set range, the selection machine can be controlled to stop to reduce the occurrence of errors. The selection machine is generally set in a constant temperature and humidity workshop. Once the air humidity in the protective cover exceeds the set range, the ventilation window is opened, and the fan can also be turned on at the same time, so that the air in the protective cover is quickly replaced, and the air humidity in the protective cover can quickly return to normal. After the ventilation window and the fan are closed, the selection machine can resume work, thereby reducing sorting errors.
[0021] 2. By setting up monitoring elements to sense whether a person is approaching, when no person is approaching and the machine is placed in a constant temperature and humidity environment, the ventilation window can remain open to make the humidity inside and outside the protective cover consistent, reducing the number of times the machine is shut down due to humidity changes. When the monitoring element senses that someone is approaching, the ventilation window is closed to prevent the air flow caused by the movement of people from affecting the air inside the protective cover. Because the baffle is always against the protective cover, its movement will not generate airflow.
[0022] 3. By setting a humidifier and / or heater in the protective cover, combined with a hygrometer and a controller, a closed-loop humidity control system can be formed, which can create a small constant temperature and humidity working atmosphere for the selection machine that is not set in a constant temperature and humidity workshop.

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0031] like Figures 1 to 4As shown, the utility model discloses a particle sorting monitoring and protection device, which includes: a protective cover 11, an on-off mechanism, a hygrometer 14, a fan 13, a controller, a monitoring element 15, a humidifier and a heater. The protective cover 11 is used to cover the sorting plate 21 of the selection machine. As a preferred solution, the protective cover 11 is directly placed on the machine table 22 of the selection machine. A sealing sponge 111 is provided at the lower edge of the protective cover 11 so that the protective cover 11 and the machine table 22 of the selection machine fit and seal better. In this state, the discharge hopper 23 and the collection box 24 of the selection machine are also covered by the protective cover 11, so that the diamond particles are in a relatively closed space throughout the sorting process. A loading door 112 and a discharging door 113 are also provided on the protective cover 11. The loading door 112 is directly opposite to the discharging hopper 23 of the selection machine. When the loading door 112 is opened, the material can be loaded onto the discharging head. The discharge door 113 is directly opposite to the collection box 24 of the selection machine, and the collection box 24 can be taken out by opening the discharge door 113. Door locks are arranged on the loading door 112 and the discharge door 113.
[0032] In addition, because the machine table 22 will vibrate during particle sorting, in order to prevent the protective cover 11 from deviating due to vibration, a suction cup or magnet for adsorbing the machine table 22 of the selection machine is provided at the bottom of the protective cover 11, and the former is preferred. As an alternative, a plurality of stoppers 25 for limiting the displacement of the protective cover 11 are provided on the machine table 22 of the selection machine, and the movement of the protective cover 11 is blocked by the stoppers 25.
[0033] In this case, the protective cover 11 is made of a transparent hard material, such as transparent plastic. At the same time, at least the top wall (defined as the magnifying wall 114) of the protective cover 11 facing the sorting disk 21 of the selection machine is designed as a convex lens structure, so that the staff can magnify to a certain extent to observe whether the rolling path of the diamond particles is the preset path.
[0034] Two ventilation windows 115 are provided on the protective cover 11, and it is preferred that the ventilation windows 115 are not higher than the sorting plate 21 of the selection machine, so as to slow down or prevent the air exchange between the inside and outside of the protective cover 11 from affecting the diamond particles on the sorting plate 21. In addition, the ventilation windows 115 are also covered with a breathable dustproof net 116, which can prevent dust from entering while allowing ventilation. Moreover, the setting of the breathable dustproof net 116 can also slow down the intensity of air exchange between the inside and outside of the protective cover 11 to a certain extent. In the absence of the fan 13 to enhance ventilation, the air exchange between the inside and outside of the protective cover cannot form airflow.
[0035] The on-off mechanism is arranged in one-to-one correspondence with the ventilation window 115, and the on-off mechanism is arranged near the ventilation window 115. The on-off mechanism includes a driving component 121 and a baffle 122, and the driving component 121 is connected to the controller. The baffle 122 is adapted to the ventilation window 115, and the baffle 122 always abuts against the wall of the protective cover 11 where the ventilation window 115 is arranged, and the driving component 121 drives the baffle 122 to cover the ventilation window 115. The on-off mechanism is placed outside the protective cover 11, so that the airflow generated when the driving component 121 is in action will not interfere with the inside of the protective cover 11. The driving component 121 can directly use a linear cylinder to push the baffle 122 to move, or the driving component 121 can directly use a rotary cylinder or a motor to drive the baffle 122 to rotate and cover the ventilation window 115. The movement trajectory of the baffle 122 is designed in this way so that no airflow is formed in the ventilation window 115 , and the opening and closing of the ventilation window 115 will not cause air flow inside the protective cover 11 .
[0036] The fan 13 is arranged inside the protective cover 11 to avoid interfering with the on-off mechanism, and at the same time, the fan 13 is arranged opposite to one of the ventilation windows 115. The fan 13 is connected to the controller. The fan 13 is used to accelerate the air replacement inside and outside the protective cover 11 when the ventilation window 115 is opened.
[0037] The hygrometer 14 is disposed in the protective cover 11 . The hygrometer 14 is used to monitor the humidity of the air in the protective cover 11 in real time. The hygrometer 14 is connected to the controller.
[0038] As a better control method, the controller sets a humidity range. When the value fed back by the hygrometer 14 is within the set range, the ventilation window 115 is always closed. At this time, the sorting of diamond particles is carried out in a relatively closed space without air flow interference. The humidity is adapted, and the interference of the environment on the sorting is eliminated, and the sorting error is smaller. When the humidity in the protective cover 11 exceeds the set range, because the controller is connected to the selection machine, the selection machine can be controlled to stop, avoiding the problem of diamond particles sticking due to inappropriate humidity, thereby avoiding the increase of the sorting error. When the selection machine is stopped, the on-off mechanism is controlled to operate, the ventilation window 115 is opened, and the fan 13 is turned on. Because the selection machine is generally set in a constant temperature and humidity workshop, the air inside and outside the protective cover 11 is quickly exchanged at this time, and the air humidity in the protective cover 11 can quickly return to the set value. After the fan 13 is turned off and the ventilation window 115 is closed, the selection machine can resume normal operation.
[0039] As another preferred control method, this method is suitable for the scenario where the selection machine is placed in a constant temperature and humidity workshop. This control method requires the use of a monitoring element 15, which is used to monitor whether a human body is approaching. The monitoring element 15 is connected to the controller, and the monitoring element 15 can be an infrared sensor. Multiple monitoring elements 15 can be set on the top of the protective cover 11 to cover the surrounding area of the current selection machine for monitoring, or monitoring elements 15 can be set on the top of the workshop or at the entrance and exit. As long as the monitoring element 15 does not detect a human body, it means that no one is approaching, the ventilation window 115 remains open, and the air inside and outside the protective cover 11 is connected. Once the monitoring element 15 detects a human body, it means that someone is approaching, and the ventilation window 115 is closed until the monitoring element 15 does not detect a human body, and the ventilation window 115 is opened again.
[0040] For the workshop where the working environment of the selection machine is not a constant temperature and humidity workshop, in this case, a constant humidity environment is constructed in the protective cover 11, and a humidifier and a heater are placed in the protective cover 11, and the humidifier and the heater are connected to the controller, and used in combination with the hygrometer 14, thereby forming a humidity closed-loop control system. Of course, if the environment where the selection machine is located is mostly a humid environment, only a heater can be set, and if the environment where the selection machine is located is mostly a dry environment, only a humidifier can be set. In addition, in the above two control methods, the humidity closed-loop control system can also be combined for use to provide fault tolerance.
[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
