Description

Technical Field

[0001] This utility model belongs to the technical field of ventilation devices, specifically relating to a mine ventilation device for safe production in mines. Background Technology

[0002] A mine shaft is a general term for the tunnels, chambers, equipment, surface buildings, and structures that form an underground coal mine production system. Sometimes, inclined shafts, vertical shafts, and adits in underground mine development are also referred to as mine shafts. A ventilation system is a device used in mines primarily to transport air from the mine shaft to the outside. Because mines are generally at considerable depths, the air inside is thin and often contains toxic gases such as methane, mine ventilation systems are widely used in this field.

[0003] The prior art publication CN219865108U provides a safe mine ventilation device. The rear end of the main body is fixedly connected to the mine ventilation duct. Then, the drive motor is started to drive the main bevel gear to rotate. The rotation of the main bevel gear drives the driven bevel gear to rotate. The rotation of the driven bevel gear drives the fan blade to rotate and deliver air into the mine ventilation duct. At the same time, the filter element can filter the air at any time. When the filter element reaches the replacement cycle, the drive gear on the square groove is driven to rotate by the square shaft handle. The rotation of the drive gear drives the drive rack to slide along the slide groove. The sliding of the drive rack drives the filter element frame to slide and replace the filter element left and right.

[0004] Although the device has many beneficial effects, it still has the following problems: when the filter elements are used alternately, the unused filter elements are directly exposed to the outside environment. There is no sealing mechanism for the unused filter elements, which makes it very easy for a large amount of mine dust to accumulate on the surface of the unused filter elements. As a result, the ventilation effect will still be affected after the filter elements are used alternately. In view of this, we propose a mine ventilation device for safe production in mines. Utility Model Content

[0005] This utility model provides a mine ventilation device for safe production in mines, solving the technical problem in the prior art where, when filter elements are used alternately, unused filter elements are directly exposed to the outside environment, lacking a sealing mechanism for unused filter elements. This easily leads to the accumulation of a large amount of mine dust on the surface of unused filter elements, thus affecting the ventilation effect even after filter element replacement. The present invention achieves the technical effect of sealing unused filter elements when one is not in use, preventing a large amount of mine dust from accumulating on the unused filter elements and affecting the subsequent ventilation effect.

[0006] The purpose of this utility model is to provide a mine ventilation device for safe production in mines, including a ventilation pipe, a connecting frame provided inside the ventilation pipe, a ventilation fan installed on one side of the connecting frame, an installation frame fixedly connected to the front of the ventilation pipe, a first slot through one side of the installation frame, a second slot through the top of the installation frame, a horizontal plate provided at the top of the installation frame, and filter screens fixedly connected to both sides of the bottom of the horizontal plate through the installation plate, so as to facilitate the alternating use of the two filter screens;

[0007] Both sides of the ventilation duct are equipped with sealing mechanisms to seal unused filters;

[0008] The sealing mechanism includes a mounting box, with connecting rods slidably connected to both sides of the bottom of the ventilation duct. A sliding plate is fixedly connected to the bottom of the connecting rod, and a movable plate is connected to the top of the sliding plate via a spring. The movable plate is connected to the mounting box, thus facilitating the sealing of unused filters.

[0009] By adopting the above technical solution and setting a sealing mechanism, when a filter screen is not in use, the unused filter screen can be sealed to prevent a large amount of mine dust from accumulating and adhering to the unused filter screen and affecting the subsequent ventilation effect.

[0010] Optionally, grooves are provided on both sides of the bottom of the ventilation duct, and sliders are slidably connected in the grooves. The top of the connecting rod is connected to the slider by screws. A guide rod is fixedly connected to the top of the slide plate. The movable plate is slidably sleeved on the outside of the guide rod. A limit plate is fixedly connected to the top of the guide rod, so that the movable plate and the mounting box can move along the direction of the guide rod.

[0011] By adopting the above technical solution and setting a guide rod, the movable plate can slide on the outside of the guide rod when the mounting box moves, thereby enabling the mounting box to move vertically along the direction of the guide rod.

[0012] Optionally, grooves are provided on both sides of the bottom of the horizontal plate, and a sealing gasket is fixedly connected to the top of the mounting box to improve the sealing effect on unused filters.

[0013] By adopting the above technical solution, and by setting grooves and sealing gaskets, it is easy to seal the gap between the top of the mounting box and the horizontal plate, reducing the possibility of external mineral dust entering the mounting box.

[0014] Optionally, the width of the inner side of the first slot is greater than the width of the inner side of the second slot. The mounting plate is slidably connected to the second slot, and the filter screen is slidably connected to the first slot. The thickness of the filter screen is greater than the thickness of the mounting plate to prevent the filter screen from rising and moving.

[0015] By adopting the above technical solution, and by limiting the filter screen and the mounting plate, since the thickness of the filter screen is greater than the thickness of the mounting plate, and the width of the inner side of the first slot is greater than the width of the inner side of the second slot, the filter screen cannot enter the second slot, thus preventing the filter screen from rising and moving. The unused filter screen is located inside the mounting box, so that the filter screen, the mounting plate and the horizontal plate will not move left and right, thus facilitating the positioning of the filter screen.

[0016] Optionally, a fixing plate is fixedly sleeved on the outside of the connecting rod, and a first threaded rod is threaded through both sides of the bottom of the fixing plate. Two threaded grooves are opened on both sides of the bottom of the ventilation pipe to facilitate the positioning of the connecting rod.

[0017] By adopting the above technical solution, and by setting a fixed plate and a first threaded rod, when there is no need to seal the filter screen, the operator can move the sliding plate to drive the connecting rod to move. The movement of the connecting rod can drive the fixed plate to move. When the fixed plate moves to the bottom of the threaded groove, the first threaded rod can be screwed into the threaded groove to position the connecting rod and the sliding plate, preventing the connecting rod and the sliding plate from moving at will.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. By setting a sealing mechanism, when a filter screen is not in use, it can be sealed to prevent a large amount of mine dust from accumulating on the unused filter screen and affecting the subsequent ventilation effect.

[0020] 2. By setting a fixed plate and a first threaded rod, when there is no need to seal the filter screen, the operator can move the slide plate to drive the connecting rod to move. The movement of the connecting rod can drive the fixed plate to move. When the fixed plate moves to the bottom of the threaded groove, the first threaded rod can be screwed into the threaded groove to position the connecting rod and the slide plate, preventing the connecting rod and the slide plate from moving at will.

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Reference Figure 1 and Figure 2 This utility model discloses a mine ventilation device for safe production in mines, including a ventilation pipe 1. A connecting frame is provided inside the ventilation pipe 1. A ventilation fan 4 is installed on one side of the connecting frame. The ventilation fan 4 is connected to an external controller and a power supply, which is prior art and will not be described in detail here. An installation frame 2 is fixedly connected to the front of the ventilation pipe 1. A first slot is opened through one side of the installation frame 2, and a second slot is opened through the top of the installation frame 2. A horizontal plate 5 is provided on the top of the installation frame 2. Filter screens 6 are fixedly connected to both sides of the bottom of the horizontal plate 5 through installation plates 9, so that the two filter screens 6 can be used alternately.

[0028] Both sides of the ventilation duct 1 are equipped with sealing mechanisms 3, which are used to seal unused filter screens 6;

[0029] The sealing mechanism 3 includes a mounting box 34. Connecting rods 30 are slidably connected to both sides of the bottom of the ventilation pipe 1. A sliding plate 31 is fixedly connected to the bottom of the connecting rod 30. A movable plate 33 is connected to the top of the sliding plate 31 through a spring 35. The movable plate 33 is connected to the mounting box 34, which facilitates the sealing of the unused filter screen 6 and prevents a large amount of mineral dust from adhering to the surface of the unused filter screen 6.

[0030] Reference Figure 2 and Figure 4 A guide rod 32 is fixedly connected to the top of the slide plate 31, and the movable plate 33 is slidably sleeved on the outside of the guide rod 32, so that the movable plate 33 and the mounting box 34 can move along the direction of the guide rod 32.

[0031] Reference Figure 2 and Figure 4 A limiting plate 36 is fixedly connected to the top of the guide rod 32. The size of the limiting plate 36 is larger than the size of the inner side of the movable plate 33, so as to prevent the movable plate 33 from separating from the guide rod 32.

[0032] Reference Figure 3 and Figure 4 The bottom sides of the horizontal plate 5 are provided with grooves 38, and the top of the mounting box 34 is fixedly connected with a sealing gasket 39 to improve the sealing effect on the unused filter screen 6.

[0033] Reference Figure 1 and Figure 4 The ventilation pipe 1 has grooves on both sides at the bottom, and a slider 37 is slidably connected in the groove. The top of the connecting rod 30 is connected to the slider 37 by screws. When there is mineral dust inside the mounting box 34, the connecting rod 30 can be separated from the slider 37, and the mounting box 34 can be removed to rinse its interior.

[0034] Reference Figure 1 and Figure 4 Both the groove and the slider 37 have T-shaped cross sections, which helps to prevent the slider 37 from detaching from the groove.

[0035] Reference Figure 3 The width of the inner side of the first slot is greater than the width of the inner side of the second slot. The mounting plate 9 is slidably connected to the second slot, and the filter screen 6 is slidably connected to the first slot. The thickness of the filter screen 6 is greater than the thickness of the mounting plate 9 to prevent the filter screen 6 from rising and moving.

[0036] Reference Figure 1 and Figure 4 A fixing plate 7 is fixedly sleeved on the outside of the connecting rod 30. The bottom sides of the fixing plate 7 are threadedly connected to the first threaded rod 8. Two threaded grooves are opened on both sides of the bottom of the ventilation pipe 1 to facilitate the positioning of the connecting rod 30.

[0037] Reference Figure 1 and Figure 2 The ventilation duct 1 is fixedly connected to the mounting brackets on both sides of the top. The mounting brackets have through grooves on both sides of the top, so that the ventilation duct 1 can be installed in the designated position by external bolts.

[0038] Reference Figure 2 The cross-section of the connecting frame is U-shaped. The ventilation fan 4 is connected to the connecting frame through the second threaded rod, which makes it easy for staff to disassemble and repair the ventilation fan 4.

[0039] The implementation principle of a mine ventilation device for mine safety production according to this utility model embodiment is as follows: When a filter screen 6 is not in use, the worker can unscrew the first threaded rod 8 from the threaded groove to release the positioning of the connecting rod 30, and then pull the movable plate 33 down to move and compress the spring 35. The movement of the movable plate 33 can drive the mounting box 34 to move. After the mounting box 34 moves down to the designated position, the sliding plate 31 is moved. The movement of the sliding plate 31 can drive the slider 37 to move through the connecting rod 30. The movement of the sliding plate 31 can drive the movable plate 33 and the mounting box 34 to move through the guide rod 32. When the slider 37 moves to abut against one side of the inner wall of the chute, the worker can release the movable plate 33, causing the compressed spring 35 to rebound and drive the sliding plate 33 to move. The movable plate 33 moves upward, which in turn moves the mounting box 34 upward, allowing it to be fitted onto the outside of the unused filter screen 6. The upward movement of the mounting box 34 also moves the sealing gasket 39 upward, causing it to insert into the groove 38 and abut against the horizontal plate 5. This helps prevent mineral dust from accumulating on the outside of the unused filter screen 6. When the filter screen 6 needs to be used alternately, simply remove the mounting box 34 from the outside of the filter screen 6 and then push the horizontal plate 5 to move. The movement of the horizontal plate 5 moves the mounting plate 9, which in turn moves the filter screen 6, allowing the unused filter screen 6 to enter the inside of the mounting frame 2, while the used filter screen 6 moves out of the mounting frame 2.

[0040] This utility model embodiment provides a mine ventilation device for safe production in mines. By setting a sealing mechanism 3, when a filter screen 6 is in an unused state, it can seal the unused filter screen 6 to prevent a large amount of mine dust from accumulating and adhering to the unused filter screen 6 and affecting the subsequent ventilation effect.
