Description

Technical Field

[0001] This utility model belongs to the field of laser lithium ore spectrometers, specifically relating to a rapid lithium element analysis device. Background Technology

[0002] Conventional lithium analysis in lithium ore or lithium-containing materials involves hydrofluoric acid-sulfuric acid decomposition, followed by detection in a sulfuric acid medium using an air-acetylene flame at 670.8 nm using a flame photometer or atomic absorption spectrometer. This entire sample preparation and analysis process takes 3-4 hours, making it difficult to monitor incoming raw material quality control and the transition of pre-furnace roasting materials in a timely manner. A rapid laser analysis method for lithium elemental analysis can quickly determine the lithium content in spodumene concentrate and lithium-containing materials. Using a portable laser analyzer, lithium analysis in lithium ore or lithium-containing materials can be performed rapidly in the 380-680 nm range. It can be used to measure lithium-containing samples at temperatures up to 500°C without damaging the instrument. Five excitations can be performed per minute, and the test can be completed within 10 minutes.

[0003] Existing laser lithium-ion spectrometers are at risk of damage to their exposed displays during portability, and continuous use can lead to internal heat buildup, causing internal components to overheat and potentially burn out. Therefore, improvements are needed. Summary of the Invention

[0004] The purpose of this invention is to provide a rapid lithium element analysis device, which solves the problem that existing laser lithium ore spectrometers are at risk of damage to their displays when carried around, due to their exposed screens. It also solves the problem that during continuous use, the internal heat cannot be dissipated, causing the internal components to be at high temperatures and easily burned out.

[0005] To achieve the above objectives, this utility model provides a rapid lithium element analysis device, including a housing. A handle is provided at the bottom of the housing, a probe is provided at the front end of the housing, and a display screen is provided at the rear end of the housing. A protective cover is hinged to the surface of the display screen, and a locking pin is fixedly connected to the top of the protective cover. A mounting base is fixedly connected to the upper left side of the housing, and the locking pin is slidably connected to the inner surface of the mounting base. A pin is slidably connected inside the mounting base, and the pin is inserted into the locking pin. A spring is provided inside the mounting base. A heat dissipation cylinder is fixedly connected to the top of the housing. An installation cylinder is threadedly connected to the inner side of the heat dissipation cylinder. A filter screen is fixedly connected to the inner side of the installation cylinder. Multiple support rods are fixedly connected to the lower inner side of the installation cylinder, and a support block is fixedly connected to all the support rods. A motor is fixedly mounted on the upper end of the support block. A rotating shaft is fixedly connected to the end of the output shaft of the motor, and a fan blade is fixedly connected to the middle section of the rotating shaft.

[0006] The principle of this utility model is as follows: In use, firstly, the latch is pulled by the lever to separate the latch from the locking pin, thus releasing the restriction on the protective cover. The protective cover is then flipped over to expose the display screen. Then, the operator holds the handle and folds the probe in half to quickly analyze lithium in lithium ore or lithium-containing materials. Moreover, when the device is in use, the motor drives the rotating shaft to rotate, which in turn drives the fan blades to rotate, thereby quickly dissipating heat from the casing. In addition, when the rotating shaft rotates, the connecting rod coaxial with the fan blades rotates synchronously. When the ball at the end of the connecting rod strikes the sliding pin, it is subjected to downward pressure, causing the top pin on the same linkage plate as the sliding pin to move down synchronously. The linkage plate compresses the second spring. When the ball and the sliding pin are misaligned, the top pin is reset under the action of the second spring and strikes the filter screen, thus ensuring that dust does not easily accumulate on the filter screen and maintaining smooth ventilation and heat dissipation.

[0007] The beneficial effects of this utility model are as follows: by setting an openable and closable protective cover on the display screen of the laser lithium ore spectrometer, the opening and closing of the protective cover can be completed by simply controlling the disengagement between the latch and the locking pin with a lever. This can provide good protection for the display screen of the laser lithium ore spectrometer and prevent it from being damaged during the process of carrying it out.

[0008] By installing a heat sink on the top of the chassis, and a detachable mounting cylinder inside the heat sink, and a fan-bladed shaft driven by an electric motor inside the mounting cylinder, the heat of the chassis can be dissipated, thus achieving the purpose of heat dissipation inside the chassis.

[0009] Furthermore, one end of the spring is fixedly connected to the pin, and the other end of the spring is fixedly connected to the inner surface of the fixing base. By using the spring, a spring force can be applied to the pin.

[0010] Furthermore, a lever is fixedly connected to the end of the pin body of the latch, and the lever passes through the fixing base and is slidably connected to the fixing base. The lever facilitates the pulling of the latch.

[0011] Furthermore, a connecting rod is fixedly connected to the upper section of the rotating shaft, and a striking ball is fixedly connected to the lower part of the connecting rod away from the rotating shaft. Through the arrangement of the striking ball, when it impacts the sliding pin, the sliding pin is subjected to a downward compressive force.

[0012] Furthermore, a hollow shell is fixedly connected to the inner wall of the mounting cylinder, and a guide rod is fixedly connected to the inner side of the hollow shell. A linkage plate is slidably sleeved on the outer side of the guide rod, and the linkage plate is slidably connected to the inner side of the hollow shell. A top pin and a sliding pin are fixedly connected to the upper end of the linkage plate. Both the top pin and the sliding pin penetrate the hollow shell and are slidably connected to it. The top pin contacts the filter screen. When the ball at the end of the connecting rod strikes the sliding pin, it is subjected to a downward compressive force, thereby causing the top pin, which is on the same linkage plate as the sliding pin, to move downward synchronously.

[0013] Furthermore, the linkage plate has ball bearings on its side, and these ball bearings are in contact with the inner wall of the hollow shell. The ball bearings reduce the friction between the linkage plate and the hollow shell.

[0014] Furthermore, a second spring is sleeved on the lower section of the guide rod. One end of the second spring is fixedly connected to the linkage plate, and the other end is fixedly connected to the inner surface of the hollow shell. The second spring provides auxiliary resetting for the top pin and sliding pin on the linkage plate. Attached Figure Description

[0021] like Figure 1 , Figure 2 , Figure 3As shown, this embodiment provides a rapid lithium element analysis device, including a housing 1. A handle 2 is located at the bottom of the housing 1, a probe 3 is located at the front end of the housing 1, and a display screen 4 is located at the rear end of the housing 1. A protective cover 5 is hinged to the surface of the display screen 4, and a locking pin 6 is fixedly connected to the top of the protective cover 5. A mounting base 7 is fixedly connected to the upper left side of the housing 1. The locking pin 6 is slidably connected to the inner surface of the mounting base 7. A pin 8 is slidably connected inside the mounting base 7 and is inserted into the locking pin 6. A spring 10 is located inside the mounting base 7. One end of the spring 10 is fixedly connected to the pin 8, and the other end of the spring 10 is fixedly connected to the inner surface of the mounting base 7. The spring 10 allows elastic force to be applied to the pin 8. A lever 9 is fixedly connected to the end of the pin 8, and the lever 9 passes through the mounting base 7 and is slidably connected to it. The lever 9 facilitates pulling the pin 8.

[0022] like Figure 4 As shown, a heat sink 11 is fixedly connected to the top of the housing 1. A mounting cylinder 12 is threadedly connected to the inner side of the heat sink 11. A filter screen 13 is fixedly connected to the inner side of the mounting cylinder 12. Multiple support rods 14 are fixedly connected to the lower inner side of the mounting cylinder 12, and a support block 15 is fixedly connected to all the support rods 14. A motor 16 is fixedly mounted on the upper end of the support block 15. A rotating shaft 17 is fixedly connected to the end of the output shaft of the motor 16, and a fan blade 18 is fixedly connected to the middle section of the rotating shaft 17. A connecting rod 19 is fixedly connected to the upper section of the rotating shaft 17, and a ball bearing 20 is fixedly connected to the lower part of the end of the connecting rod 19 away from the rotating shaft 17. Through the arrangement of the ball bearing 20, it impacts the sliding pin 26, causing the sliding pin 26 to experience a downward compressive force.

[0023] like Figure 4 As shown, a hollow shell 21 is fixedly connected to the inner wall of the mounting cylinder 12. A guide rod 22 is fixedly connected to the inner side of the hollow shell 21. A linkage plate 23 is slidably sleeved on the outer side of the guide rod 22, and the linkage plate 23 is slidably connected to the inner side of the hollow shell 21. A top pin 25 and a sliding pin 26 are fixedly connected to the upper end of the linkage plate 23. Both the top pin 25 and the sliding pin 26 penetrate the hollow shell 21 and are slidably connected to it. The top pin 25 contacts the filter screen 13. When the ball 20 at the end of the connecting rod 19 strikes the sliding pin 26, it is subjected to a downward squeezing force, thereby causing the top pin 25, which is on the same linkage plate 23 as the sliding pin 26, to move down synchronously. A ball bearing 24 is provided on the side of the linkage plate 23, and the ball bearing 24 contacts the inner wall of the hollow shell 21. The ball bearing 24 reduces the friction between the linkage plate 23 and the hollow shell 21. A second spring 27 is fitted onto the lower section of the guide rod 22. One end of the second spring 27 is fixedly connected to the linkage plate 23, and the other end is fixedly connected to the inner surface of the hollow shell 21. The second spring 27 provides auxiliary reset for the top pin 25 and the sliding pin 26 on the linkage plate 23.

[0024] The specific implementation process of this utility model is as follows: In use, firstly, the latch 8 is pulled by the lever 9 to separate the latch 8 from the locking pin 6, thus releasing the restriction on the protective cover 5. The protective cover 5 is then flipped over to expose the display screen 4. Then, the operator holds the handle 2 and folds the probe 3 over the lithium ore to quickly analyze lithium in the lithium ore or lithium-containing materials. Furthermore, during use, the motor 16 drives the rotating shaft 17 to rotate, which in turn drives the fan blades 18 to rotate, thereby quickly dissipating heat from the casing 1. When the shaft 17 rotates, the connecting rod 19, which is coaxial with the fan blade 18, rotates synchronously. When the ball 20 at the end of the connecting rod 19 hits the sliding pin 26, it is subjected to downward pressure, which causes the top pin 25, which is on the same linkage plate 23 as the sliding pin 26, to move down synchronously. The linkage plate 23 compresses the second spring 27. When the ball 20 and the sliding pin 26 are misaligned, the top pin 25 is reset under the action of the second spring 27 and hits the filter screen 13, thus ensuring that dust does not easily accumulate on the filter screen 13 and maintaining smooth ventilation and heat dissipation.

[0025] This solution involves installing a closable protective cover 5 on the display screen 4 of the laser lithium ore spectrometer. The protective cover 5 can be opened and closed simply by controlling the engagement and disengagement between the latch 8 and the locking pin 6 using the lever 9. This provides excellent protection for the display screen 4 of the laser lithium ore spectrometer, preventing damage during transport.

[0026] By setting a heat dissipation cylinder 11 on the top of the housing 1, and setting a detachable mounting cylinder 12 inside the heat dissipation cylinder 11, and setting a rotating shaft 17 driven by a motor 16 and equipped with fan blades 18 inside the mounting cylinder 12, the heat of the housing 1 can be discharged, thereby achieving the purpose of heat dissipation inside the housing 1.
