Description

Technical Field

[0001] The utility model relates to the technical field of condensers, in particular to a water-removing and reflux-proof condenser. Background Art

[0002] A dewatering anti-reflux condenser is a device used in industrial or laboratory distillation processes. Its main function is to condense steam and convert it back to a liquid state while preventing the condensate from flowing back into the evaporation source or reaction vessel. This condenser usually includes a cooling system, which can be cooling water or other cooling media to reduce the temperature of the condensed steam and condense it. However, when the existing dewatering anti-reflux condenser is used, the water inlet is located at the lower part of the condenser, so a certain amount of cooling water is easily retained. If this residual water is not treated, it will wet the laboratory table.

[0003] For example, Chinese patent 202221400020.4 discloses a dewatering anti-reflux condenser, in which a mounting plate is installed inside the water inlet, and a sliding rod is provided on the mounting plate, and the sliding rod is slidably connected to the mounting plate, so that when the water inlet is separated from the water pipe, the plug can block the through hole. However, the above-mentioned condenser still has the following shortcomings when in use: because the water inlet is located at a lower position of the condenser, it tends to retain a certain amount of cooling water therein. If these residual cooling waters are not properly handled, the laboratory work surface may become damp, affecting the normal operation of the experiment.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0008] Furthermore, in order to prevent the backflow of cooling water, the anti-backflow mechanism includes a connecting plate arranged at the end of the water inlet away from the outer tube, a through hole is arranged in the middle of the connecting plate, a cylinder is arranged at the end of the connecting plate close to the water inlet, and a water hole is arranged on the side wall of the cylinder.

[0009] Furthermore, in order to prevent the backflow of cooling water, the anti-backflow mechanism also includes a mounting hole arranged in the middle of one end of the cylinder away from the connecting plate, a spring is arranged in the mounting hole, a sliding plate is arranged near one end of the connecting plate and located in the mounting hole, and a plug is arranged at one end of the sliding plate near the connecting plate; the connecting plate and the water inlet are connected by a plurality of bolts, and nuts are sleeved on the ends of the bolts.

[0010] Furthermore, in order to prevent residual water from flowing to the test bench after the external water pipe is removed, the water removal mechanism includes a pipe arranged at the end of the anti-backflow mechanism away from the water inlet, and a water injection connection hole is arranged at the end of the pipe away from the anti-backflow mechanism.

[0011] Furthermore, in order to prevent residual water from flowing toward the test bench after the external water pipe is removed, the water removal mechanism also includes a cavity arranged at the bottom end of the pipe, a baffle is arranged at the bottom end of the cavity, a sealing piston is arranged inside the cavity, and a pull rod is arranged at the bottom end of the sealing piston; an L-shaped plate is arranged at the bottom end of the baffle, a square through groove is arranged at the bottom end of the L-shaped plate, the bottom end of the pull rod passes through the baffle and extends to the bottom of the L-shaped plate, and a square pull plate is arranged at the bottom end of the pull rod.

[0014] (2) By setting up an anti-backflow mechanism, water is allowed to flow through during normal operation. When the water flow pressure disappears, the through hole is closed by a plug to prevent the backflow of cooling water, thereby ensuring the normal operation of the condenser and the dryness of the laboratory working environment.

[0015] (3) By setting up a water removal mechanism, the residual water in the pipeline can be removed by operating the pull rod and the square pull plate to drive the sealing piston to descend, so that when the external water pipe is removed, no residual water will flow to the laboratory table; and through the cooperation of the square through groove and the square pull plate, the square pull plate can descend when it is parallel to the square through groove, and can block the descent of the sealing piston when the square pull plate is perpendicular to the square through groove, thereby maintaining the stability of the sealing piston.

[0023] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments. They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in the field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0024] According to an embodiment of the utility model, a water removal and anti-reflux condenser is provided.

[0025] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-4 As shown, the water-removing and anti-reflux condenser according to the embodiment of the utility model includes an outer tube 1, an inner tube 2 is arranged inside the outer tube 1, a condensation inlet 3 is arranged at the top end of the inner tube 2, and a condensation outlet 8 is arranged at the bottom end of the inner tube 2; a water outlet 4 is arranged on the top side wall of the outer tube 1, a water inlet 5 is arranged on the bottom side wall of the outer tube 1, an anti-reflux mechanism 6 is arranged at the end of the water inlet 5 away from the outer tube 1, and a water-removing mechanism 7 is arranged at the end of the anti-reflux mechanism 6 away from the water inlet 5.

[0026] By means of the above scheme, the utility model can prevent cooling water from flowing back at the water inlet of the condenser, thereby preventing the laboratory work surface from getting damp and affecting the normal operation of the experiment.

[0027] In one embodiment, for the above-mentioned backflow prevention mechanism 6, the backflow prevention mechanism 6 includes a connecting plate 601 arranged at the end of the water inlet 5 away from the outer tube 1, a through hole 602 is arranged in the middle of the connecting plate 601, a cylinder 603 is arranged at the end of the connecting plate 601 close to the water inlet 5, and a water hole 604 is arranged on the side wall of the cylinder 603; the backflow prevention mechanism 6 also includes a mounting hole 605 arranged in the middle of the end of the cylinder 603 away from the connecting plate 601, a spring 606 is arranged in the mounting hole 605, and a sliding plate 607 is arranged near one end of the connecting plate 601 and located in the mounting hole 605. A plug 608 is provided at one end of the sliding plate 607 close to the connecting plate 601, wherein in the specific design, the plug 608 and the through hole 602 are both set to a conical structure; the connecting plate 601 is connected to the water inlet 5 by a plurality of bolts 609, and the ends of the bolts 609 are sleeved with nuts 610, so that the elastic force of the spring 606 can be effectively used to control the position of the sliding plate 607, thereby allowing water to flow through during normal operation, and closing the through hole 602 by the plug 608 when the water flow pressure disappears, preventing the backflow of cooling water, thereby ensuring the normal operation of the condenser and the dryness of the laboratory working environment.

[0028] The working principle of the backflow prevention mechanism 6 is as follows: under normal working conditions, the plug 608 is flushed open, and cooling water flows into the outer tube 1 through the through hole 602 and the water hole 604. When the cooling system stops supplying water and the water flow pressure disappears, the spring 606 pushes the sliding plate 607 to make the plug 608 close the through hole 602, preventing the water inside the condenser from flowing back to the water inlet 5 due to gravity, thereby ensuring that the laboratory work surface is dry and avoids moisture.

[0029] In one embodiment, for the above-mentioned water removal mechanism 7, the water removal mechanism 7 includes a pipe 701 arranged at the end of the anti-backflow mechanism 6 away from the water inlet 5, and the end of the pipe 701 away from the anti-backflow mechanism 6 is provided with a water injection connection hole 702, and at the same time, the water injection connection hole 702 is tapped so that the water injection connection hole 702 is connected to the external water pipe joint; the water removal mechanism 7 also includes a cavity 703 arranged at the bottom end of the pipe 701, the bottom end of the cavity 703 is provided with a baffle 704, the interior of the cavity 703 is provided with a sealing piston 705, and the bottom end of the sealing piston 705 is provided with a pull rod 706; the bottom end of the baffle 704 is provided with an L-shaped plate 707, and the bottom end of the L-shaped plate 707 is provided with a A square through groove 708 is provided, and the bottom end of the pull rod 706 passes through the baffle 704 and extends to the bottom of the L-shaped plate 707, and a square pull plate 709 is provided at the bottom end of the pull rod 706, so that the residual water in the pipeline 701 can be removed by operating the pull rod 706 and the square pull plate 709 to drive the sealing piston 705 to descend, and then when the external water pipe is removed, no residual water will flow to the experimental bench; and through the cooperation of the square through groove 708 and the square pull plate 709, the square pull plate 709 can descend when it is parallel to the square through groove 708, and can block the descent of the sealing piston 705 when the square pull plate 709 is perpendicular to the square through groove 708, thereby maintaining the stability of the sealing piston 705.

[0030] The working principle of the water removal mechanism 7 is as follows: by operating the pull rod 706, the user can control the up and down movement of the sealing piston 705. When it is necessary to remove the water in the pipeline 701, the user pulls the pull rod 706 to drive the square pull plate 709 to descend. At this time, the square pull plate 709 is parallel to the square through groove 708, so that the sealing piston 705 descends, and the residual water in the pipeline 701 is sucked into the cavity 703, and the residual water in the pipeline 701 is removed. At this time, after the external water pipe is removed, no residual water will flow out to the laboratory platform. After reconnecting the water pipe, push the sealing piston 705 upward to make the residual water return to the pipeline 701, and turn the pull rod 706 to make the square pull plate 709 perpendicular to the square through groove 708. At this time, the square pull plate 709 blocks the sealing piston 705 from descending and maintains it in a stable position.

[0031] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0032] In actual application, the steam enters the inner tube 2 through the condensation inlet 3 of the inner tube 2, and the cooling water introduced into the outer tube 1 through the water inlet 5 absorbs the heat of the steam, causing the steam to condense into liquid. The condensed liquid is discharged through the condensation outlet 8 at the bottom end of the inner tube 2. The anti-backflow mechanism 6 prevents the water in the condenser from flowing back to the water inlet 5, thereby protecting the laboratory work surface from drying. The water removal mechanism 7 allows the user to remove the residual water in the pipeline 701 after the condenser is stopped.

[0033] In summary, the utility model can prevent cooling water from flowing back at the water inlet of the condenser, thereby preventing the laboratory work surface from getting damp and affecting the normal operation of the experiment. By setting the anti-backflow mechanism 6, water is allowed to flow through during normal operation, and the through hole 602 is closed by the plug 608 when the water flow pressure disappears to prevent the backflow of cooling water, thereby ensuring the normal operation of the condenser and the dryness of the laboratory working environment. By setting the water removal mechanism 7, the residual water in the pipeline 701 can be removed by operating the pull rod 706 and the square pull plate 709 to drive the sealing piston 705 to descend, and then when the external water pipe is removed, no residual water will flow to the laboratory table; and through the cooperation of the square through groove 708 and the square pull plate 709, the square pull plate 709 can descend when it is parallel to the square through groove 708, and the square pull plate 709 can block the descent of the sealing piston 705 when it is perpendicular to the square through groove 708, so as to keep the sealing piston 705 stable.

Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.
