Description

Technical Field

[0001] The utility model relates to the technical field of switching valve transportation, and particularly relates to a novel material switching valve. Background Art

[0002] In the existing switching valves or reversing valves, during the use process, both sides of the flap are prone to adhering materials, and the side plates on both sides of the switching valve are also prone to adhering materials, which easily causes unsmooth feeding or blockage.

[0003] For example, a three-way reversing valve for preventing ash blockage disclosed in CN201922448205.7 includes a valve body, a valve plate seat, a valve plate, a cylinder, and a pneumatic vibrator. The pneumatic vibrator is installed on one side of the valve body, the valve plate seat is installed on the other side of the valve body, the valve plate is installed in the valve body, and is connected to the cylinder installed outside the valve body through a connecting shaft of the valve plate seat. In the utility model, by vibrating the outer wall of the three-way reversing valve with the pneumatic vibrator, the ash blocking frequency is significantly reduced, the number of manual cleanings is reduced, and the risk of boiler load reduction is avoided. Its disadvantages are as follows: By vibrating the outer wall of the three-way reversing valve with the pneumatic vibrator, due to the thick wall of the reversing valve, the vibration transmission effect is poor, and the adhered materials may not necessarily fall; if the power of the vibration is too large, the wall of the reversing valve is easily deformed. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a novel material switching valve with good scraping effect of the scraper.

[0006] A rotating cylinder is arranged under the flap. The rotating cylinder passes through the switching valve and is rotatably connected to the switching valve. An opening is arranged under the rotating cylinder, and the lower end of the scraper is fixed on a telescopic rod.

[0007] Side wall scraping plates are arranged on the side edges of the flap. At the joint where the side wall scraping plates are in contact with the side wall of the switching valve, when the flap rotates, the materials on the side wall of the switching valve are scraped off.

[0008] It is convenient to install and fix the scraper, and avoid materials from adhering to the telescopic rod; the telescopic rod of the driving mechanism is located in the rotating cylinder, the scraper is sleeved on the flap, and the lower end of the scraper is fixed on the telescopic rod.

[0009] The longitudinal section of the flap is triangular, the scraper is of a U-shaped structure, and the movement of the telescopic rod of the driving mechanism drives the scraper to move.

[0010] A second driving mechanism for driving the flap to rotate is arranged on the switching valve.

[0011] The rotary drum is connected to the second driving mechanism through a connecting plate.

[0012] The second driving mechanism adopts an electric telescopic rod, pneumatic start or hydraulic start.

Four side wall scraping plates are arranged on the sides of the two surfaces of the flap, and the four side wall scraping plates can scrape off the materials on the side wall of the switching valve.

[0024] Embodiment 1: As Figure 1-7 shown, a new type of material switching valve includes a switching valve 1 and a flap 3 arranged in the switching valve 1. A scraping plate 7 is arranged on the flap 3, and a driving mechanism 6 for driving the scraping plate 7 to move is arranged on the switching valve 1.

[0025] The difference between Example 2 and Example 1 is that: on the side edge of the flap 3, there is a side wall scraping plate 2. Where the side wall scraping plate 2 is in contact with the side wall 11 of the switching valve, when the flap rotates, the side wall scraping plate shovels off the materials on the side wall of the switching valve.

[0026] The difference between Example 3 and Example 2 is that: under the flap 3, there is a rotating cylinder 8. The rotating cylinder 3 passes through the switching valve 1 and is rotatably connected to the switching valve 1. Under the rotating cylinder 8, there is an opening 9, which is convenient for installing and fixing the scraping plate 7 to prevent materials from adhering to the telescopic rod 10. The telescopic rod 10 of the driving mechanism is located inside the rotating cylinder 8. The scraping plate 7 is sleeved on the flap 3, and the lower end of the scraping plate 7 is fixed on the telescopic rod 10.

[0027] The difference between Example 4 and Example 3 is that: the longitudinal section of the flap 3 is triangular, the scraping plate 7 is of a U-shaped structure. The movement of the telescopic rod 10 of the driving mechanism drives the movement of the scraping plate 7. The scraping plate 7 is clamped on two surfaces of the flap 3. After the scraping plate 7 moves, it shovels off the materials on the two surfaces of the flap 3.

[0028] The difference between Example 5 and Example 4 is that: on the switching valve 1, there is a second driving mechanism 5 for driving the rotation of the flap 3.

[0029] The difference between Example 6 and Example 5 is that: the rotating cylinder 8 is connected to the second driving mechanism 5 through a connecting plate 4. One end of the second driving mechanism is hinged to the connecting plate, and the other end is hinged to the switching valve. The second driving mechanism 5 drives the rotation of the rotating cylinder 8, and the rotating cylinder 8 drives the rotation of the flap 3.

[0030] The difference between Example 7 and Example 6 is that: the second driving mechanism adopts electric start or hydraulic start.

[0031] The difference between Example 8 and Example 7 is that: the driving mechanism adopts an electric telescopic rod, pneumatic or hydraulic start.

[0032] When this switching valve is in use, the second driving mechanism drives the flap to rotate left and right. Four side wall scraping plates are arranged on the side edges of the two surfaces of the flap. The four side wall scraping plates can shovel off the materials on the side wall of the switching valve.

[0033] The second driving mechanism drives the flap to rotate right, and the feeding port on the left side of the switching valve opens for feeding; the second driving mechanism drives the flap to rotate left, and the feeding port on the right side of the three-way valve opens for feeding; the telescopic rod of the driving mechanism extends or contracts, driving the scraping plate fixed on the telescopic rod to move left and right, shoveling off the materials adhering to the flap; the driving mechanism can adopt an electric telescopic rod, and the operation is more stable; the second driving mechanism and the driving mechanism work regularly to prevent materials from adhering to the flap and the scraping plate.
