However, the present invention may be embodied in other forms different from those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0018] References herein to "one embodiment" or "an embodiment" refer to particular features, structures, or characteristics that may be included in at least one implementation of the invention. The appearances of the phrase "in one embodiment" in various places in the specification do not necessarily all refer to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.
[0019] 1 to 5, which are the first embodiment of the present invention, provide a heat pipe heat exchanger device for cooling water in a nuclear power plant, and a filtering net 101 is provided for filtering. When the filtering net 101 is seriously clogged, the motor 201 is started, and the moving column 204b pushes the filtering net 101 to shake off impurities and dust, and at the same time, the cleaning brush 103a performs cleaning.
[0020] Specifically, the processing device K includes a housing K-1, an intake hole K-11, an exhaust port K-12, a water supply port K-13, and a drain port K-14, each of which is provided on the outer wall of the housing K-1, and a heat pipe K-15 provided inside the housing K-1. The clogging prevention assembly 100 includes a filter net 101 provided inside the housing K-1, a groove 101a provided on the outer wall of the filter net 101, a partition plate 102 provided inside the housing K-1, and a through-hole on the outer wall of the partition plate 102. The drive assembly 200 includes a motor 201, a set plate 201a provided below the motor 201, and a rotating shaft 201b provided at the output end of the motor 201. The ash cleaning assembly 300 includes a storage chamber 301 provided inside the housing K-1, a guide rail 301a provided on the inner wall of the storage chamber 301, an ash collection box 302 movably provided inside the storage chamber 301, and a guide groove 302a opened in the outer wall of the ash collection box 302.
[0021] In addition, grooves 101a are provided on the two side walls of the filtering screen 101, and ash drop grooves 102a are used to drop the dust from the ash drop grooves 102a into the ash collection box 302 after the cleaning brush 103a has removed the dust. The outer wall of the set plate 201a is fixedly connected to the housing K-1, and the set plate 201a is used to position the motor 201. The guide rail 301a is movably fitted into the guide groove 302a, and after the movable door 306 is opened, the ash collection box 302 can be pulled out to dispose of the dust.
[0022] As described above, after the filter net 101 has been used for a certain period of time, serious clogging occurs, reducing the filtering effect. In this case, the motor 201 is started, and the cleaning brush 103a on the mounting plate 103 removes dust from the partition plate 102, while the movable column 204b shakes off the impurities accumulated on the filter net 101.
[0023] Referring to Figures 1 to 5 as Example 2, this is the second example of the present invention, which is based on the above example, with the following differences: after starting the motor 201, the turntable 202 rotates, which causes the movable rod 202a-1 to move correspondingly, so that the movable column 204b can shake off the dust accumulated on the filtration screen 101, and at the same time, the cleaning brush 103a on the mounting plate 103 moves left and right to remove the dust.
[0024] Specifically, a bump 101b is provided on the inner wall of the housing K-1, and the bump 101b is movably fitted into the groove 101a, a movable passage 102b is opened on the outer wall of the partition plate 102, a mounting plate 103 is movably provided above the partition plate 102, and a cleaning brush 103a is provided below the mounting plate 103.
[0025] Preferably, a rotating disk 202 is provided at one end of the rotating shaft 201b, a first rotating column 202a is provided on the outer wall of the rotating disk 202, a movable rod 202a-1 is provided on the outer wall of the first rotating column 202a, an operating rod 202a-12 is provided at one end of the movable rod 202a-1, and a movable frame 203 is provided outside the mounting plate 103.
[0026] Furthermore, due to the provision of the bumps 101b and the grooves 101a, the filter screen 101 can move up and down and shake off impurities clogging it as it is pushed by the moving column 204b. Furthermore, the relatively wide areas above and below the bumps 101b prevent the filter screen 101 from falling or being pushed away from its corresponding position. The provision of the partition plate 102 allows impurities accumulated on the filter screen 101 to fall onto the partition plate 102. The cleaning brush 103a can remove dust and other impurities accumulated above the partition plate 102. The first rotating column 202a and the rotating disk 202 are eccentrically arranged. One end of the movable rod 202a-1 is movably connected to the first rotating column 202a, and the other end is movably connected to the mounting plate 103.
[0027] Preferably, an engaging groove 203a is provided inside the movable frame 203, and the engaging groove 203a is movably engaged with the operating rod 202a-12, a first slide groove 203b is provided on the outer wall of the movable frame 203, a positioning plate 203b-1 is provided above the mounting plate 103, and the positioning plate 203b-1 is movably engaged with the first slide groove 203b, and a connecting plate 204 is provided above the positioning plate 203b-1.
[0028] Preferably, a through hole 204a is provided on the outer wall of the connecting plate 204, a movable column 204b is movably provided inside the through hole 204a, the lower part of the movable column 204b is connected to the movable frame 203, and an elastic member 204b-1 is externally fitted on the outer wall of the movable column 204b, a push rod 205 is provided on the side wall of the mounting plate 103, and the push rod 205 is movably fitted into the movable passage 102b.
[0029] In addition, an operating rod 202a-12 is movably provided at one end of the movable rod 202a-1 away from the first rotating pillar 202a, and a positioning plate 203b-1 is not only connected and fixed to the connecting plate 204 but can also fit into the first slide groove 203b, thereby fulfilling the positioning function of the movable frame 203. The elastic member 204b-1 is preferably a compression spring and is provided between the movable frame 203 and the connecting plate 204. It is preferable to provide four movable pillars 204b. After the motor 201 is started, the rotating shaft 201b rotates, thereby rotating the turntable 202, and the first rotating column 202a movably engages with the movable rod 202a-1, so that the cleaning brush 103a on the mounting plate 103 performs cleaning work. At the same time as the movable rod 202a-1 moves, the operating rod 202a-12 drives the movable frame 203 to move up and down, so that the movable column 204b displaces up and down, and further pushes and moves the filter screen 101 to shake off the accumulated dust.
[0030] As described above, in order to prevent clogging of the filter screen 101 after a certain period of use, which may affect the filtering effect of the filter screen 101, the motor 201 is started to drive the movable rod 202a-1 on the turntable 202, which then moves the cleaning brush 103a to remove dust accumulated on the partition plate 102. At the same time, the movable column 204b moves, which further vibrates the filter screen 101, thereby preventing clogging of the filter screen 101.
[0031] Referring to Figures 1 to 7 for Example 3, this is a third example of the present invention, which is based on the above-mentioned example, with the following differences: when the mounting plate 103 is driven to move, the push rod 205 drives the transmission rack 303 to move, which causes the transmission gear 304 to rotate, the slide rod 304a-11 to move, and then the movable door 306 to move upward, which facilitates the operator to directly remove and dispose of the dust in the ash collecting box 302.
[0032] Specifically, a transmission rack 303 is provided at one end of the push rod 205, a transmission gear 304 is provided on the outer wall of the transmission rack 303 in meshing engagement with the transmission gear 304, and a second rotating column 304a is provided on the outer wall of the transmission gear 304.
[0033] Preferably, a second slide groove 304a-1 is provided on the outer wall of the second rotating shaft 304a, a slide rod 304a-11 is provided on the outer wall of the second slide groove 304a-1, and an orientation groove 304a-12 is provided on the outer wall of the slide rod 304a-11.
[0034] Preferably, a push plate 305 is provided at one end of the slide rod 304a-11, a directional guide groove 303a is provided on the inner wall of the storage chamber 301, and the directional guide groove 303a is movably fitted with the transmission rack 303, a push column 305a is provided above the push plate 305, a third slide groove 306b and a fourth slide groove 306a-1 are provided on the outer wall of the housing K-1, respectively, and a movable door 306 is movably provided inside the third slide groove 306b.
[0035] In addition, the transmission gear 304 is movably connected to the inner wall of the receiving chamber 301, the second rotating column 304a is eccentrically connected to the transmission gear 304, the outer wall of the orientation groove 304a-12 is connected to the inner wall of the receiving chamber 301, the direction guide groove 303a is used to limit the displacement direction of the transmission rack 303, and it is preferable that two push columns 305a are provided symmetrically, and the third slide groove 306b and the fourth slide groove 306a-1 are provided symmetrically. It is preferable that the movable passage 102b is provided so as to movably engage with the push rod 205. The installation of the movable passage 102b not only limits the displacement direction of the mounting plate 103, but also connects the push rod 205 to the outer wall of the mounting plate 103. When the mounting plate 103 moves, the push rod 205 is driven, so that the transmission rack 303 is movably engaged with the transmission gear 304, thereby rotating the transmission gear 304.
[0036] Preferably, a mounting block 306a is provided on the outer wall of the movable door 306, and the mounting block 306a is movably fitted into the fourth slide groove 306a-1, and the push post 305a is movably fitted into the mounting block 306a.
[0037] Preferably, a first engaging rod 307 is movably mounted on the outer wall of the movable door 306, an engaging block 307b is mounted on the outer wall of the housing K-1, and a second engaging rod 307a is mounted between the engaging block 307b and the first engaging rod 307, and a handle 307a-1 is mounted on the outer wall of the second engaging rod 307a.
[0038] In addition, it is preferable that two mounting blocks 306a are provided symmetrically. After the transmission gear 304 rotates, the slide rod 304a-11 moves correspondingly, so that the push column 305a on the push plate 305 pushes the mounting block 306a upward, i.e., moves the movable door 306 upward, and the first engaging rod 307 correspondingly rotates to above the engaging block 307b, thereby allowing the movable door 306 to be opened, thereby facilitating the withdrawal of the ash collection box 302 and facilitating the operator to promptly remove dust introduced into the ash collection box 302 from the ash drop groove 102a, and ensuring that the inside of the housing K-1 is cleaned cleanly.
[0039] As described above, after the dust on the partition plate 102 is swept into the ash collecting box 302, it needs to be removed by the worker in a timely manner, thereby ensuring the cleanliness of the inside of the housing K-1. By providing the transmission gear 304, when the mounting plate 103 moves, the transmission rack 303 is driven to engage with the transmission gear 304, so that the transmission gear 304 rotates, and the push column 305a further pushes the mounting block 306a, and the movable door 306 opens, facilitating removal by the worker.
