Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
As shown in fig. 1 and fig. 2, an embodiment discloses a collecting device, which includes a housing 100 and a shielding member 200, wherein an accommodating chamber 101 is provided in the housing 100, the housing 100 is provided with a water inlet 102 and a water outlet 103 communicated with the accommodating chamber 101, the shielding member 200 is provided in the accommodating chamber 101 and rotatably connected to the housing 100, the shielding member 200 is used for covering the water outlet 103, and the shielding member 200 can rotate under the action of buoyancy to separate the shielding member 200 from the water outlet 103.
In the collecting device, liquid can enter the accommodating cavity 101 from the water inlet 102, meanwhile, smoke can enter the accommodating cavity 101 from the water inlet 102 to increase the air pressure in the accommodating cavity 101, when the liquid level is low, the shielding piece 200 is under the action of the air pressure and the self gravity, so that the shielding piece 200 is tightly attached to the water outlet 103, the smoke cannot leak, when the liquid accumulates in the accommodating cavity 101, along with the rise of the liquid level, the liquid level partially submerges the shielding piece 200, the air pressure borne by the shielding piece 200 is reduced, meanwhile, the shielding piece 200 is under the increasingly large buoyancy, when the buoyancy borne by the shielding piece 200 is larger than the self gravity of the shielding piece 200, the shielding piece 200 can float and rotate under the action of the buoyancy, at the moment, the liquid can be discharged from a gap between the shielding piece 200 and the water outlet 103, and along with the discharge of the liquid, the liquid level descends, so that the shielding piece 200 can, the smoke and the like are prevented from leaking out of the water outlet 103, the shielding piece 200 is rotatably connected with the shell 100 and is more sensitive to the rising or falling of the liquid level, the water outlet 103 can be timely reset and covered again when the liquid level falls, and the smoke and the like can be better prevented from leaking out of the water outlet 103 while liquid can be discharged.
Specifically, because the shielding element 200 is rotatably connected with the housing 100, when the shielding element 200 is subjected to buoyancy, the shielding element 200 is limited by the connection position, so that the shielding element 200 can realize regular displacement, that is, the shielding element 200 can also lift along with the lifting of the liquid level in the accommodating chamber 101, and the shielding element 200 can still cover the water outlet 103 after falling, so that other limiting structures do not need to be arranged in the accommodating chamber 101, the structure in the accommodating chamber 101 can be simplified, the situation that the space in the accommodating chamber 101 is occupied by other limiting structures is reduced, the liquid accommodating capacity of the accommodating chamber 101 is improved, and then under the same accommodating capacity, the volume of the collecting device can be smaller, and the space occupation of the collecting device is reduced. Compared with the traditional structures such as a floating ball, the motion track of the shielding piece 200 is determined in the process of downwards moving and covering the water outlet 103 again, the shielding piece 200 can quickly and accurately return and cover the water outlet 103, and the smoke in the accommodating cavity 101 is prevented from leaking through the water outlet 103.
In one embodiment, as shown in fig. 1 and fig. 2, a water drainage pipe 110 is disposed on the casing 100, the water drainage pipe 110 penetrates through the casing 100, an opening at one end of the water drainage pipe 110 located in the accommodating cavity 101 is the water outlet 103, an end surface of the water drainage pipe 110 located in the accommodating cavity 101 is a contact surface for contacting with the shielding member 200, and the contact surface is inclined with respect to a horizontal plane. When the contact surface is inclined with respect to the horizontal, the shield 200 is attached to the contact surface before floating, also in an inclined arrangement, when the liquid level in the receiving chamber 101 rises, a part of the shield 200 is first submerged in the liquid and subjected to buoyancy, also, in the case where the shutter 200 is rotatably coupled to the housing 100, the shutter 200 may float, similar to the lever principle, with less buoyancy required for the shutter 200 to float, therefore, the shielding piece 200 is easier to float, so that the shielding piece 200 can be lifted in time, the liquid in the accommodating cavity 101 is discharged from the water outlet 103, meanwhile, the opening of the drain pipe 110 at one end in the accommodating cavity 101 is the water outlet 103, the liquid in the accommodating cavity 101 needs to be accumulated to a certain height to float the shielding piece 200 and be discharged from the water outlet 103, and the liquid can be precipitated in the accumulation process, so that impurities in the liquid can be reduced from entering the water outlet 103.
In one embodiment, as shown in fig. 1 and 2, a rotating seat 120 rotatably connected to the shielding member 200 is disposed on an inner wall of the accommodating chamber 101, and one side of the contact surface close to the rotating seat 120 is higher than the other side of the contact surface. Since the side of the contact surface close to the rotating seat 120 is higher than the other side of the contact surface, the end of the shielding piece 200 far from the rotating seat 120 is lower than the end of the shielding piece 200 close to the rotating seat 120, when the shielding piece 200 rotates, the displacement amplitude of the end of the shielding piece 200 far from the rotating seat 120 is larger than the end of the shielding piece 200 close to the rotating seat 120, that is, the gap between the side of the contact surface far from the rotating seat 120 and the shielding piece 200 is larger than the gap between the other side of the contact surface and the shielding piece 200, so that the liquid can be discharged from the gap between the side of the contact surface close to the rotating seat 120 and the shielding piece 200 as soon as possible, and when the liquid level drops, the liquid level will be exposed at first on the side of the contact surface close to the rotating seat 120, but because the gap between the side of the contact surface close to the rotating seat 120 and the shielding piece 200 is smaller, the smoke in the accommodating cavity 101 is not easy to enter, then the shielding piece 200 is completely contacted with the contact surface, so that the liquid is prevented from being discharged continuously, and the smoke gas does not return to the water outlet 103 to leak, therefore, the structure can better prevent the smoke gas from leaking in the liquid discharging process.
Alternatively, as shown in fig. 1 and 2, the other end of the drain pipe 110 extends out of the housing 100 and may be externally connected with a pipeline for draining water.
In other embodiments, the contact surface may also be disposed horizontally; or one side of the contact surface close to the rotating seat 120 may be lower than the other side of the contact surface.
In one embodiment, as shown in fig. 1 and 2, a deposition portion 130 is disposed on an inner wall of the accommodating chamber 101 and corresponds to the water inlet 102, and the deposition portion 130 is spaced apart from the water outlet pipe 110. Liquid can get into and hold chamber 101 by water inlet 102 in, because settling part 130 sets up with water inlet 102 corresponds, and settling part 130 sets up with drain pipe 110 interval, liquid gets into and holds chamber 101 after can directly not be discharged by drain pipe 110, but at first deposit impurity in settling part 130, consequently can prevent that impurity from getting into in the water inlet 102.
In one embodiment, as shown in fig. 1 and 2, the deposition portion 130 is disposed on a side of the rotating base 120 away from the drain pipe 110. At this time, the rotating seat 120 can play a certain role in blocking, so as to prevent impurities deposited in the deposition portion 130 from affecting the rotation of the shutter 200, and meanwhile, since the side of the contact surface close to the rotating seat 120 is higher, the deposited impurities are not easy to enter the water inlet 102.
In one embodiment, as shown in fig. 1 and 3, the collecting device further includes a plug 131, the inner wall of the accommodating cavity 101 is recessed toward the outside of the housing 100 to form the depositing portion 130, a cleaning opening is formed at the bottom of the depositing portion 130, and the plug 131 is used for blocking the cleaning opening. The liquid that gets into at this moment and hold chamber 101 can deposit impurity at settling part 130, and through opening end cap 131, can clear up the accumulational impurity in settling part 130, and it is more convenient to clear up.
Optionally, plug 131 is an interference fit with the clearance opening; or plug 131 is threadably engaged with the clearance opening. Above mode all can realize that end cap 131 blocks up the clearance opening, can take off end cap 131 when needs clearance simultaneously.
Optionally, as shown in fig. 1 and fig. 3, the collecting device further includes a first sealing ring 133, and the first sealing ring 133 is sleeved outside the plug 131. The first sealing ring 133 is used for sealing to prevent liquid from flowing out from the gap between the plug 131 and the inner wall of the cleaning opening.
In one embodiment, as shown in fig. 1 and 3, the collecting device further includes a pin 132, a through hole is formed on the depositing portion 130, and the pin 132 sequentially penetrates through the through hole and the plug 131. Can carry on spacingly to end cap 131 through bolt 132, prevent that end cap 131 from breaking away from the clearance opening in the use, when the impurity of deposit portion 130 is cleared up to needs simultaneously, can pull out bolt 132 earlier, pull out end cap 131 again.
Specifically, a slot and an annular groove are formed in the outer side surface of the plug 131, the pin 132 sequentially penetrates through the through hole and the slot, the annular groove is used for installing the first sealing ring 133, the slot is formed in one side, far away from the accommodating cavity 101, of the annular groove, at the moment, although the pin 132 sequentially inserts the deposition portion 130 and the plug 131, due to the sealing effect of the first sealing ring 133, liquid and impurities in the accommodating cavity 101 cannot flow out of the casing 100 through the portion, inserted into the deposition portion 130 and the plug 131, of the pin 132, and the sealing effect is guaranteed.
In one embodiment, as shown in fig. 1 and 2, the housing 100 is provided with a water inlet tube 140, and when the shielding member 200 covers the water outlet 103, a lowest point of the water inlet tube 140 is higher than or equal to a highest point of the shielding member 200. Because can get into the flue gas in holding chamber 101, lead to holding the atmospheric pressure in the chamber 101 and rise, therefore if the liquid level with the water inlet 102 back parallel and level, water inlet 102 is sealed by the liquid level, air and flue gas in holding chamber 101 can not be discharged, it is just difficult that liquid gets into holding chamber 101 by water inlet 102 again, if make shielding piece 200 can float and pivoted liquid level be less than the minimum that is higher than inlet tube 140, can influence the normal opening of shielding piece 200, be unfavorable for holding the discharge of the interior liquid of chamber 101, consequently set up the minimum of inlet tube 140 to be higher than or equal to the peak of shielding piece 200, shielding piece 200 must float and rotate when guaranteeing the liquid level and the terminal surface parallel and level of inlet tube 140, make liquid discharge smoothly.
Specifically, when the liquid level in the accommodating cavity 101 is level with the end surface of the water inlet pipe 140, if the shielding member 200 is made of a material with a relatively high density, the shielding member 200 is completely submerged, and the shielding member 200 is subjected to the maximum buoyancy force, but because the shielding member 200 can float under the action of the buoyancy force, the shielding member 200 can necessarily float when the shielding member 200 is subjected to the maximum buoyancy force or less, and therefore when the lowest point of the water inlet pipe 140 is higher than or equal to the highest point of the shielding member 200, the effect of discharging liquid and preventing smoke leakage can be ensured by the shielding member 200.
