Description

Technical Field

[0001] This application relates to the field of coal quality analysis, and in particular, to a tailings coal quality analyzer. Background Art

[0002] Tailings are the waste residues generated after separating useful minerals from gangue, surrounding rock, etc. through processes such as ore dressing during coal mining. Tailings usually include waste residues composed of ore, gangue, surrounding rock, etc., which contain a certain amount of useful minerals but also some harmful substances. Therefore, the treatment and utilization of mine tailings are important environmental protection and resource utilization issues. During the process of tailings separation and treatment, a coal quality analyzer is usually required to detect the coal quality of the separated tailings.

[0003] Existing coal quality analyzers mainly carry out chemical analysis and testing of coal samples through physical and chemical methods. When the coal quality analyzer is working, heat is generated inside, and usually, heat dissipation holes are opened on the outer wall of the coal quality analyzer and the heat is discharged through a heat dissipation device.

[0004] The above-mentioned existing technical solutions have the following defects: When the coal quality analyzer stops working, a large amount of dust will accumulate at the heat dissipation holes, and even block the heat dissipation holes after long-term use, reducing the heat dissipation effect of the coal quality analyzer. Content of the Utility Model

[0005] This application provides a tailings coal quality analyzer to ensure the normal operation of the heat dissipation device of the coal quality analyzer.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] A tailings coal quality analyzer includes a box body, and a heat dissipation device and a dust-proof device are installed on the side wall of the box body. The dust-proof device is located on the side of the heat dissipation device away from the box body, and the dust-proof device can seal the heat dissipation device.

[0008] The dust-proof device includes a dust-proof plate, a locking component, and a fixing block. The dust-proof plate is hinged to the box body, the plate surface of the dust-proof plate can cover the heat dissipation device, the locking component is arranged on the outer wall of the box body, and the fixing block is fixedly arranged on the dust-proof plate. When the dust-proof plate closes the heat dissipation device, the locking end of the locking component can be inserted into the fixing block.

[0009] By adopting the above technical solution, when using the analyzer, the locking component is released from limiting the fixing block, and the dust-proof plate is rotated away from the heat dissipation holes to ensure that the heat dissipation device can balance the temperature inside and outside the box body. When the detection work is over, the heat dissipation device stops working, the dust-proof plate is rotated to cover the heat dissipation device, and at the same time, the locking component limits the fixing block, which can prevent dust from entering the box body, ensure that the heat dissipation holes are not blocked by dust, and ensure the normal operation of the heat dissipation device.

[0010] Optionally, the locking assembly includes a locking block, which is fixedly connected to the side wall of the box body, and a cavity is provided in the locking block. A locking rod is inserted into and slidably arranged in the locking block, and one end of the locking rod is processed to form a spherical shape with a smooth surface. A baffle is fixedly connected to the peripheral wall of the locking rod, and the baffle is located in the locking block and fits with the inner wall of the locking block on the side close to the heat dissipation device. A first elastic member is sleeved on the peripheral wall of the locking rod, and the first elastic member is located in the locking block and its two ends are respectively abutted against the locking block and the baffle. A locking hole is provided on the fixed block, and the locking rod can be inserted into the locking hole.

[0011] By adopting the above technical solution, when the dustproof plate is located at the opening of the heat dissipation hole, the first elastic member can push the baffle to allow the locking rod to be inserted into the locking hole. The locking rod limits the fixed block to ensure that the dustproof plate can cover the heat dissipation hole. When using the analyzer, the locking rod is pulled to release the limit on the limit block, and the dustproof plate is rotated away from the heat dissipation device to ensure that the heat dissipation device can work normally.

[0012] Optionally, there are multiple lock holes.

[0013] By adopting the above technical solution, when a sealing strip is added to the dustproof plate, the overall thickness of the dustproof plate will increase. When the dustproof plate is rotated to cover the heat dissipation device, the locking rod is inserted into the corresponding lock hole, which can increase the use scenarios of the locking assembly.

[0014] Optionally, an anti-collision block is fixedly connected to the side wall of the box body. When the dustproof plate turns away from the plate surface of the sealing strip and approaches the box body, the anti-collision block fits with the fixed block. A second elastic part is fixedly connected to the anti-collision block. A spherical clamping block is fixedly connected to one end of the second elastic part. The spherical clamping block can be embedded in the lock hole and limit the fixed block. When the fixed block approaches or moves away from the second elastic part, the fixed block can push the spherical clamping block and cause the second elastic part to deform.

[0015] By adopting the above technical solution, it is possible to ensure that the dustproof plate is away from the heat dissipation hole when the analyzer is working, and to ensure the normal operation of the heat dissipation device. When the analyzer is finished working, the dustproof plate is rotated to make the spherical clamping block slide out of the lock hole, and the limit on the fixed block is released. When the heat dissipation device is working, the dustproof plate is limited by clamping, and the influence of the rotation of the dustproof plate on the heat dissipation effect of the heat dissipation device is reduced.

[0016] Optionally, a side wall of the box body is provided with a heat dissipation hole, and the heat dissipation device includes a mounting frame, which is fixedly connected to the opening of the heat dissipation hole. A cooling fan is installed on one side of the mounting frame, and a dustproof net is detachably connected to the other side.

[0017] By adopting the above technical solution, when the analyzer is working, the cooling fan rotates to balance the temperature inside and outside the box body. At the same time, the dust-proof net can block the dust outside the box from entering the box body or adhering to the fan blades of the cooling fan. After the detection work is completed, the staff can remove the dust-proof net for cleaning. The dust-proof net is detachably connected to the mounting rack, which is convenient for the staff to clean in time and ensures that the dust-proof net is not blocked.

[0018] Optionally, a sealing door is hinged to one side of the box body, and a lock device is arranged on the sealing door. The lock device includes a lock ring, the lock ring is fixedly connected to the sealing door, a lock groove is formed on the box body, and a lock tongue is rotatably connected in the lock groove.

[0019] By adopting the above technical solution, when the sealing door is closed, the lock ring is inserted into the lock groove and fits against the bottom of the lock tongue. The lock ring continues to move towards the bottom of the lock groove. At this time, the lock ring will push the lock tongue to rotate. When the end of the lock ring away from the sealing door moves to the bottom of the lock groove, the lock ring leaves the lock tongue and the lock tongue rotates under the action of gravity. At this time, the lock tongue limits the lock ring and prevents the sealing door from being opened. When it is necessary to open the sealing door, pull the top end of the lock tongue to make it rotate. At this time, the bottom end of the lock tongue is away from the lock ring and the limit on the sealing door is released. By limiting the lock ring with the lock tongue, it is convenient for the staff to open and close the sealing door.

[0020] Optionally, a torsion spring is fixedly connected to the side plate of the lock groove, and one end of the torsion spring abuts against the lock tongue.

[0021] By adopting the above technical solution, the stability of the lock tongue limiting the lock ring can be increased under the elastic force of the torsion spring, and the sealing performance of the sealing door can be ensured.

[0022] Optionally, a support seat is fixedly connected to the bottom of the box body. A universal wheel is installed on one side of the support seat. A screw is threadedly connected to the support seat, and an anti-slip seat is fixedly connected to one end of the screw.

[0023] By adopting the above technical solution, the staff can freely push the box body to move. After moving to the working area, rotate the anti-slip seat to make the screw rotate and extend out of the support seat until the universal wheel is away from the ground. At this time, adjust the distance between the four corners of the bottom of the box body and the ground by rotating the anti-slip seat to make the box body placed horizontally, ensuring that the box body can be stably placed on the ground and ensuring the stability of the analyzer during coal quality analysis work.

[0024] In summary, the present application has the following technical effects:

[0025] 1. By setting a dust-proof plate, a locking assembly and a fixing block, when using the analyzer, the locking assembly releases the limit on the fixing block, and the dust-proof plate is rotated away from the heat dissipation holes, ensuring that the heat dissipation device can balance the temperature inside and outside the box. When the detection work is over, the heat dissipation device stops working, the dust-proof plate is rotated to cover the heat dissipation device, and at the same time the locking assembly limits the fixing block, which can prevent dust from entering the box and ensure that the heat dissipation holes are not blocked by dust, thus ensuring that the heat dissipation device can work normally;

[0026] 2. By setting a shock-absorbing block, a second elastic member and a spherical clamping block, it can ensure that the dust-proof plate is away from the heat dissipation holes when the analyzer is working, ensuring the normal operation of the heat dissipation device. When the analyzer finishes working, the dust-proof plate is rotated so that the spherical clamping block slides out of the locking hole, releasing the limit on the fixing block. When the heat dissipation device is working, the dust-proof plate is limited by clamping, reducing the influence of the rotation of the dust-proof plate on the heat dissipation effect of the heat dissipation device;

[0027] 3. By setting an installation frame, a heat dissipation fan and a dust-proof net, when the analyzer is working, the heat dissipation fan rotates to balance the temperature inside and outside the box. At the same time, the dust-proof net can prevent dust outside the box from entering the box or adhering to the fan blades of the heat dissipation fan. When the detection work is over, the staff can remove the dust-proof net for cleaning. The dust-proof net is detachably connected to the installation frame, facilitating the staff to clean it in time and ensuring that the dust-proof net is not blocked. Description of the Drawings

[0036] The present application is further described in detail below in conjunction with the accompanying drawings.

[0037] The present application embodiment discloses a tailings coal quality analyzer, referring to Figure 1 and Figure 2 The analyzer includes a box body 1, a sealing door 11 is hinged on one side of the box body 1, and an observation window 12 is installed on the sealing door 11. A heat dissipation device 3 and a dustproof device 4 are installed on the wall on one side of the length direction of the box body 1. The dustproof device 4 is located on the side of the heat dissipation device 3 away from the box body 1, and the dustproof device 4 can cover the heat dissipation device 3 and seal the heat dissipation device 3.

[0038] Reference Figure 2 The heat dissipation device 3 includes a mounting frame 31, which is made of a metal ring and has a criss-cross-shaped metal frame welded inside. A heat dissipation hole 32 is opened on the wall on one side of the length direction of the box body 1. The mounting frame 31 is fixed to the opening of the heat dissipation hole 32 by bolts. A heat dissipation fan 33 is installed on the side of the mounting frame 31 facing the inside of the box body 1, and a dustproof net 34 is detachably connected to the side of the mounting frame 31 away from the heat dissipation fan 33 by bolts.

[0039] Reference Figure 2 and Figure 3 The dustproof device 4 includes a dustproof plate 41, which is hinged on the side wall of the box body 1 where the heat dissipation hole 32 is opened. The plate surface area of ​​the dustproof plate 41 is larger than the area of ​​the opening of the heat dissipation hole 32. The dustproof plate 41 can cover the heat dissipation hole 32. A sealing strip 42 is arranged on the plate surface of the dustproof plate 41 facing the side of the box body 1. The sealing strip 42 is arranged along the plate edge of the dustproof plate 41. The sealing strip 42 is made of an elastic rubber strip and has a V-shaped cross-section. Both ends of the sealing strip 42 are bonded to the side plate of the dustproof plate 41. An exhaust hole is opened on the side wall of the sealing strip 42 facing the outside of the box body 1, and a plurality of exhaust holes are opened along the length direction of the sealing strip 42.

[0040] Reference Figure 4A locking block 43 is fixedly connected to the side wall of the box body 1 with a dustproof plate 41 by bolts. The locking block 43 and the dustproof plate 41 are respectively located on the two sides opposite to the heat dissipation hole 32. A cavity is opened inside the locking block 43, and locking rods 44 are penetrated and slidably arranged at both ends of the locking block 43. One end of the locking rod 44 extends out of the locking block 43 and is processed to form a spherical shape with a smooth surface. The other end of the locking rod 44 extends out of the locking block 43 and is welded with a spherical handle 45. A baffle 46 is welded on a section of the locking rod 44 away from the spherical handle 45. The baffle 46 is located in the locking block 43 and fits with the side wall of the locking block 43 away from the spherical handle 45. A first elastic member 441 is sleeved on the peripheral wall of the locking rod 44. The first elastic member 441 is located in the locking block 43 and its two ends are respectively abutted on the locking block 43 and the baffle 46. In this embodiment, the first elastic member 441 is a spring. The locking block 43, the locking rod 44, the ball handle 45 and the baffle 46 form a locking assembly. A fixing block 47 is fixedly connected to the plate surface of the dustproof plate 41 on the side away from the box body 1. The fixing block 47 is located on the plate surface of the dustproof plate 41 away from the hinge side of the dustproof plate 41. The fixing block 47 is provided with a locking hole 48. There are two locking holes 48 along the length direction of the fixing block 47. The locking rod 44 can be inserted into the locking hole 48 and limit the fixing block 47.

[0041] When using the analyzer, pull the ball handle 45 to move the lock rod 44 away from the lock hole 48, release the limit on the fixed block 47, and rotate the dust plate 41 to move it away from the heat dissipation hole 32. When the analyzer is working, the cooling fan 33 rotates to balance the temperature inside and outside the box 1. At the same time, the dust net 34 can prevent dust outside the box 1 from entering the box 1 or being adsorbed on the fan blades of the cooling fan 33. When the detection work is completed, the staff can remove the dust net 34 for cleaning. The dust net 34 is detachably connected to the mounting frame 31, which is convenient for the staff to clean in time and ensure that the dust net 34 is not blocked. When the dustproof plate 41 is rotated to cover the heat dissipation hole 32, the fixed block 47 contacts the locking rod 44 and pushes the locking rod 44 to move away from the fixed block 47. When the locking hole 48 is opposite to the locking rod 44, the first elastic member 441 extends and pushes the locking rod 44 to insert into the locking hole 48. The locking rod 44 is inserted into the locking hole 48 to limit the fixed block 47, so that the dustproof plate 41 can cover the heat dissipation hole 32. At the same time, the sealing strip 42 can prevent dust and dirt from entering the box body 1, thereby ensuring that the heat dissipation hole 32 is not blocked by dust and ensuring that the heat dissipation device 3 can work normally.

[0042] Reference Figure 2 and Figure 3, on one side of the box body 1 where the dust-proof plate 41 is hinged, an anti-collision block 5 is fixedly connected by bolts. When the plate surface of the dust-proof plate 41 facing away from the sealing strip 42 rotates and approaches the box body 1, the fixing block 47 fits against the anti-collision block 5. On the side of the anti-collision block 5 away from the dust-proof plate 41, a second elastic member 51 is fixedly connected by bolts. In this embodiment, the second elastic member 51 is an elastic member made of an elastic metal plate. One end of the second elastic member 51 away from the anti-collision block 5 is welded with a spherical clamping block, and the spherical clamping block can be inserted into the lock hole 48 to limit the fixing block 47. When the fixing block 47 approaches or moves away from the second elastic member 51, the fixing block 47 can push the spherical clamping block and cause the second elastic member 51 to deform.

[0043] When using this analyzer, rotate the dust-proof plate 41 to make it away from the heat dissipation hole 32. When the dust-proof plate 41 rotates to approach the spherical clamping block, the second elastic member 51 deforms. At the same time, the fixing block 47 moves while fitting against the spherical clamping block. When the lock hole 48 moves to the position of the spherical clamping block, the spherical clamping block is inserted into the lock hole 48 and limits the fixing block 47 at the same time, ensuring that the dust-proof plate 41 is away from the heat dissipation hole 32 when the analyzer is working and ensuring the normal operation of the heat dissipation device 3. When the analyzer finishes working, rotate the dust-proof plate 41 to make the spherical clamping block slide out of the lock hole 48, releasing the limit on the fixing block 47. When the heat dissipation device 3 is working, the dust-proof plate 41 is limited by clamping, reducing the influence of the rotation of the dust-proof plate 41 on the heat dissipation effect of the heat dissipation device 3.

[0044] Refer to Figure 5 and Figure 6 , a lock device 2 is provided at the top of the sealing door 11. The lock device 2 includes a lock ring 21. The lock ring 21 is U-shaped and both ends of the lock ring 21 are fixedly connected to the top of the sealing door 11 by bolts. A lock groove 22 is opened at the top of the box body 1 near the lock ring 21. A lock tongue 23 is rotatably connected to the inner wall of the lock groove 22. The lock tongue 23 is L-shaped and one end is rotatably connected to the inner wall of the lock groove 22. A torsion spring is fixedly connected to the side wall of the lock groove 22. The torsion spring is located at the rotation position of the lock tongue 23, and one end of the torsion spring abuts against the lock tongue 23.

[0045] When using this analyzer, when closing the sealing door 11, the lock ring 21 is inserted into the lock groove 22 and fits against the bottom of the lock tongue 23. The lock ring 21 continues to move towards the bottom of the lock groove 22. At this time, the lock ring 21 will push the lock tongue 23 to rotate. When the end of the lock ring 21 away from the sealing door 11 moves to the bottom of the lock groove 22, the lock ring 21 leaves the lock tongue 23 and the lock tongue 23 rotates under the action of gravity. At this time, the lock tongue 23 limits the lock ring 21 and prevents the sealing door 11 from being opened. When it is necessary to open the sealing door 11, pull the top end of the lock tongue 23 to make it rotate. At this time, the bottom end of the lock tongue 23 moves away from the lock ring 21 and releases the limit on the sealing door 11. Limiting the lock ring 21 by the lock tongue 23 facilitates the staff to open and close the sealing door 11.

[0046] Refer to Figure 7, a support base 6 is welded to the bottom of the box body 1. There are four support bases 6, which are respectively located at the four corners of the bottom surface of the box body 1. A universal wheel 61 is installed on the side of the support base 6 facing away from the box body 1. A screw rod 62 is threadedly connected to the side of the support base 6 facing away from the box body 1. A non-slip seat 63 is welded to one end of the screw rod 62 away from the support base 6.

[0047] When using this analyzer, rotate the non-slip seat 63 to make the screw rod 62 rotate and screw into the support base 6 until the universal wheel 61 contacts the ground and the non-slip seat 63 is away from the ground. At this time, the staff can freely push the box body 1 to move, which is convenient for the staff to move the analyzer. After moving to the working area, rotate the non-slip seat 63 to make the screw rod 62 rotate and extend out of the support base 6 until the universal wheel 61 is away from the ground. At this time, adjust the distances between the four corners of the bottom of the box body 1 and the ground by rotating the four non-slip seats 63 respectively to make the box body 1 placed horizontally, ensuring that the box body 1 can be stably placed on the ground and ensuring the stability of the analyzer during coal quality analysis work.

[0048] This specific embodiment is only an explanation of the present application, and it is not a limitation of the present application. Those skilled in the art can make modifications to this embodiment without creative contributions according to needs after reading this specification, but as long as it is within the scope of the claims of the present application, it is protected by the patent law.
