[0023] As Figures 1 to 6 shown, the present utility model provides a horizontal externally heated vacuum furnace filtering device, including a base 1, a support base 2 is fixedly installed above the base 1, a vacuum furnace 3 is fixedly installed above the support base 2, a round pipe 4 is fixedly installed at the front end of the vacuum furnace 3, a filter table 5 is fixedly installed at the front end of the round pipe 4, a connecting pipe 6 is fixedly installed at the front end of the filter table 5, a bottom ring block 7 is fixedly sleeved on the outer side of the connecting pipe 6, an outer ring block 8 is fixedly sleeved on the outer side of the bottom ring block 7, a circular ring block 9 located above the bottom ring block 7 is fixedly installed inside the outer ring block 8, slots 10 are opened on both sides of the circular ring block 9, a connecting ring 13 is movably installed between the inner side of the circular ring block 9 and the outer side of the bottom ring block 7, a feed pipe 17 is movably installed at the front end of the connecting ring 13, and a first filter plate 18 is fixedly installed inside the feed pipe 17.

[0024] When it is necessary to install the feed pipe 17 at the front end of the vacuum furnace 3, first take out the connecting ring 13, place the feed pipe 17 above the vacuum furnace 3, then rotate the feed pipe 17 so that the threaded groove ring 16 is connected to the threaded ring 15, then insert the card block 14 into the slot 10, so that the card block 14 squeezes the telescopic spring 12, causing the telescopic spring 12 to deform, then rotate the feed pipe 17, rotate the card block 14 below the card slot 11, and after releasing the hand, the telescopic spring 12 releases elastic potential energy to push the card block 14 into the card slot 11, thereby installing the feed pipe 17 at the front end of the vacuum furnace 3.

[0025] By rotating the feed pipe 17, the connection between the spiral groove ring 16 and the thread ring 15 is made. Then, the clamping block 14 is inserted into the inside of the slot 10, and the clamping block 14 is rotated to the lower side of the clamping groove 11. After releasing the hand, the telescopic spring 12 releases the elastic potential energy to push the clamping block 14 into the inside of the clamping groove 11, thereby installing the feed pipe 17 at the front end of the vacuum furnace 3. Compared with the traditional horizontal externally heated vacuum furnace, this horizontal externally heated vacuum furnace filtering device can complete the installation and disassembly of the feed pipe 17 by inserting and rotating the feed pipe 17, which is convenient for the installation and replacement of the filter plate one 18.

[0026] Among them, a placement groove 19 is opened on the lower side of the filter table 5. A pull ring 22 is movably installed inside the filter table 5. Above the pull ring 22, a connecting rod 21 extending outside the placement groove 19 is fixedly installed. On the outside of the connecting rod 21, a filter plate two 20 is fixedly installed. Inside the filter table 5, movable grooves 23 are opened on both sides of the placement groove 19. Inside the movable grooves 23, inclined blocks 24 are movably installed, and the inclined blocks 24 correspond to the pull ring 22.

[0027] When the pull ring 22 needs to be replaced, only need to pull up the filter plate two 20, so that the filter plate two 20 drives the connecting rod 21 to move upward, the connecting rod 21 drives the pull ring 22 to move upward, so that the pull ring 22 squeezes the inclined block 24, causing the inclined block 24 to contract into the inside of the movable groove 23, thereby squeezing the return spring 27 and deforming the return spring 27. At this time, the inclined block 24 drives the limit block 26 to move inside the limit groove 25 to limit the inclined block 24, so that the inclined block 24 contracts into the inside of the movable groove 23, thereby taking out the pull ring 22.

[0028] By pulling up the filter plate two 20, the pull ring 22 squeezes the inclined block 24, causing the inclined block 24 to contract into the inside of the movable groove 23, thereby taking out the pull ring 22. Compared with the traditional horizontal externally heated vacuum furnace, this horizontal externally heated vacuum furnace filtering device can take out the pull ring 22 by pulling up the filter plate two 20, causing the inclined block 24 to contract into the inside of the movable groove 23, which is convenient for the installation and disassembly of the pull ring 22.

[0029] Among them, a clamping groove 11 is opened at the bottom of the circular ring block 9. On the outside of the connecting ring 13, a clamping block 14 is fixedly installed, and the clamping block 14 corresponds to the clamping groove 11.

[0030] Rotate the clamping block 14 to the lower side of the clamping groove 11. After releasing the hand, the telescopic spring 12 releases the elastic potential energy to push the clamping block 14 into the inside of the clamping groove 11, thereby installing the feed pipe 17 at the front end of the vacuum furnace 3.

[0031] Among them, a thread ring 15 is fixedly installed above the connecting ring 13. At the bottom of the feed pipe 17, a spiral groove ring 16 is fixedly installed, and the thread ring 15 corresponds to the spiral groove ring 16.

[0032] Place the feed pipe 17 above the vacuum furnace 3, and then rotate the feed pipe 17 to connect the spiral groove ring 16 with the thread ring 15.

[0033] Wherein, a telescopic spring 12 is elastically installed on the outer side of the bottom ring block 7, and the telescopic spring 12 is located below the clamping block 14.

[0034] Insert the clamping block 14 into the inside of the slot 10, so that the clamping block 14 squeezes the telescopic spring 12, causing the telescopic spring 12 to deform, and the telescopic spring 12 releases elastic potential energy to push the clamping block 14 into the inside of the clamping groove 11.

[0035] Wherein, a reset spring 27 is elastically installed at the bottom of the movable groove 23, and the reset spring 27 is located inside the inclined block 24.

[0036] The connecting rod 21 drives the pull ring 22 to move upward, so that the pull ring 22 squeezes the inclined block 24, causing the inclined block 24 to contract into the inside of the movable groove 23, thereby squeezing the reset spring 27 and causing the reset spring 27 to deform.

[0037] Wherein, limiting grooves 25 are opened on both sides of the movable groove 23, limiting blocks 26 are fixedly installed on both sides of the inclined block 24, and the limiting blocks 26 are movably connected inside the limiting grooves 25.

[0038] The inclined block 24 drives the limiting block 26 to move inside the limiting groove 25, thereby limiting the inclined block 24 through the limiting block 26.

[0039] The working principle and usage process of the present utility model:

[0040] When it is necessary to install the feed pipe 17 at the front end of the vacuum furnace 3, first take out the connecting ring 13, place the feed pipe 17 above the vacuum furnace 3, then rotate the feed pipe 17 to connect the spiral groove ring 16 with the thread ring 15, then insert the clamping block 14 into the inside of the slot 10, so that the clamping block 14 squeezes the telescopic spring 12, causing the telescopic spring 12 to deform, then rotate the feed pipe 17 to rotate the clamping block 14 below the clamping groove 11, and after releasing the hand, the telescopic spring 12 releases elastic potential energy to push the clamping block 14 into the inside of the clamping groove 11, thereby installing the feed pipe 17 at the front end of the vacuum furnace 3.

[0041] When it is necessary to replace the pull ring 22, simply pull up the second filter plate 20, so that the second filter plate 20 drives the connecting rod 21 to move upward, and the connecting rod 21 drives the pull ring 22 to move upward, causing the pull ring 22 to squeeze the inclined block 24, so that the inclined block 24 contracts into the interior of the movable groove 23, thereby squeezing the return spring 27 and deforming the return spring 27. At this time, the inclined block 24 drives the limiting block 26 to move inside the limiting groove 25 to limit the inclined block 24, so that the inclined block 24 contracts into the interior of the movable groove 23, thereby removing the pull ring 22.
