Description

Technical Field

[0001] The utility model relates to the technical field of air heaters, in particular to a flow rate increasing device for a drain pipe of an air heater. Background Art

[0002] The drain pipe of the heater is a piping system used to remove condensed water inside the heater. In the heating system, the heater raises the indoor temperature by heating the air. In this process, since the air contains moisture, when this humid air flows through the heater, part of the water vapor will condense into water droplets. If these water droplets are not discharged in time, they will accumulate inside the heater, which may cause the performance of the equipment to deteriorate or even damage it.

[0003] A filter is usually installed inside the existing drain pipe to filter impurities in the water. However, over time, moisture and dust in the environment come into contact with the filter, causing dirt to accumulate and cause the filter to become clogged, which not only affects the water flow rate, but also causes a decrease in equipment efficiency and may even cause equipment damage. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a flow rate increasing device for a drain pipe of a heater.

[0005] The utility model is implemented by the following technical scheme: a flow rate increasing device for a drain pipe of a heater, comprising a drain pipe, a flange fixedly connected to the surface of the drain pipe, a filter screen arranged inside the drain pipe, a cleaning assembly arranged inside the drain pipe, and an installation groove opened on the inner wall of the drain pipe;

[0006] The cleaning assembly includes a rotating rod, the surface of which is fixedly connected to an impeller, the surface of which is rotatably connected to a connecting sleeve, the surface of which is fixedly connected to a mounting rod, the end of the mounting rod away from the connecting sleeve is fixedly connected to a fixing ring, the inner wall of the fixing ring is threadedly connected to a threaded rod, and the surface of the rotating rod is fixedly connected to a cleaning scraper.

[0007] Through the above technical solution, the impeller is rotated by the water flow, which can increase the flow rate of the fluid and improve the drainage efficiency of the drain pipe. As the rotating rod rotates, the two scrapers rotate to clean the surface of the filter screen without the need for external force, thereby improving convenience during use and effectively avoiding clogging of the filter screen and affecting the water flow rate.

[0008] As a further improvement of the above solution, the right end of the rotating rod passes through the filter screen, the impeller is located at the left end of the fixed ring, and the number of the mounting rods is five, and the five mounting rods are distributed around the fixed ring.

[0009] Through the above technical solution, the stability of the connecting bearing is improved through the five mounting rods.

[0010] As a further improvement of the above solution, the fixing ring is arc-shaped, and one end of the threaded rod passes through the filter screen and is threadedly connected to the inner wall of the mounting groove.

[0011] Through the above technical solution, the arc-shaped fixing ring avoids blocking the water flow, and the water flows into the interior of the drain pipe through the lower end of the fixing ring.

[0012] As a further improvement of the above solution, the number of the cleaning scrapers is two, and the ends of the two cleaning scrapers close to each other are in contact with the two ends of the filter screen.

[0013] Through the above technical solution, the two ends of the filter are cleaned by two cleaning scrapers, which effectively avoids the filter from being blocked and keeps the filter unobstructed.

[0014] As a further improvement of the above solution, the right end of the rotating rod is fixedly connected to a fixed rod, the number of the fixed rods is provided with two, and one end of the two fixed rods away from each other is fixedly connected to a fixed side plate.

[0015] Through the above technical solution, the supporting stability of the connecting rod is improved by the two fixed side plates.

[0016] As a further improvement of the above solution, the inner wall of the fixed side plate is rotatably connected to a connecting rod, a fixed disc is provided at the lower end of the fixed rod, and the inner wall of the fixed disc is fixedly connected to the surface of the connecting rod.

[0017] Through the above technical solution, the fixed disc can be rotated through the connecting rod.

[0018] As a further improvement of the above solution, a toggle piece is fixedly connected to the surface of the fixed disc, and the number of the toggle pieces is set to be several, and the several toggle pieces are distributed around the circumference of the fixed disc.

[0019] Through the above technical solution, the water flow drives the toggle plate to rotate, which increases the interaction with the water flow, further improves the flow rate of the water flow, and facilitates the rapid discharge of the water flow.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] The utility model provides a cleaning component, specifically, when the water flow contacts the impeller, the impeller is driven to rotate and the rotating rod is driven to rotate, so that the flow rate of the fluid can be increased and the drainage efficiency of the drain pipe can be improved. As the rotating rod rotates, the two cleaning scrapers are driven to rotate. The surface of the filter screen is cleaned by the cleaning scrapers, and the impurities on the surface of the filter screen can be effectively cleaned, which effectively avoids the clogging of the filter screen and keeps the filter screen unobstructed, avoiding the clogging and affecting the flow rate of the water flow, and saving energy by driving by water flow, thereby improving practicality. The cleaning component and the filter screen can be disassembled by disassembling the threaded rod, which is convenient for subsequent maintenance and improves convenience during use.

[0022] The utility model provides a connecting rod, a fixed disc and a toggle plate. Specifically, when the water flow contacts the toggle plate, the toggle plate drives the fixed disc to rotate on the surface of the connecting rod, so that a plurality of toggle plates contact the water flow, thereby increasing the interaction with the fluid, further improving the flow rate of the water flow, and facilitating the rapid discharge of the water flow.
