Description

Technical Field

[0001] The present application relates to the technical field of discharge devices, and in particular to a powder discharge device. Background Art

[0002] When discharging powdery materials, they tend to accumulate in the discharge bin and cause blockage. For example, in the sludge gasification process, a certain proportion of lime powder needs to be added before the sludge enters the gasifier for gasification and combustion to reduce the sulfur dioxide produced by the sludge during the gasification process. Lime powder is generally stored in a lime powder silo; and because lime powder has the characteristics of light weight, poor fluidity, easy compaction and easy expansion due to moisture, it tends to accumulate at the bottom of the lime powder silo and cause blockage.

[0003] In order to reduce the occurrence of powder blockage, the existing method is to set an auxiliary unloading device such as a rotary scraper at the bottom of the silo to push the powder at the bottom of the silo; when a lot of powder is accumulated, the rotary scraper will bend or even break due to excessive resistance, making the rotary scraper lose its function and causing powder blockage.

[0023] The high material level meter and the low material level meter are both electrically connected to the first vibrator and the second vibrator;

[0024] The high material level meter is used to stop the first vibrator and the second vibrator when detecting that the accumulation height of the powder material is higher than the high material level meter;

[0046] The technical solutions of the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the specification of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection requested by the present application.

[0047] In the description of the embodiments of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0048] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a replaceable connection, or an integral connection, it can be a mechanical connection, it can be an electrical connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0049] See also Figure 1 and Figure 2 A powder material unloading device provided in an embodiment of the present application includes: a silo 10, a first cone 21 and a unloading mechanism 50; the sharp corner of the first cone 21 is arranged upward in the discharge port 11 of the silo 10; the unloading mechanism 50 is connected to the discharge port 11 of the silo 10.

[0050] In this embodiment, the first cone 21 is spaced from the silo 10; specifically, the first cone 21 is spaced from the silo 10 on all sides, so that the material can fall from between the first cone 21 and the silo 10 to the lower part of the discharge port 11. During the material discharge process, the powder 80 falling on the first cone 21 will pass through the first cone 21 and be diverted to the surroundings of the first cone 21, realizing diverted and segmented material discharge, thereby reducing the pressure of the powder 80 at the discharge port 11 of the silo 10 and above the discharge mechanism 50, reducing the situation of the powder 80 being squeezed and piled up at the discharge port 11 of the silo 10 and above the discharge mechanism 50, thereby improving the stability of the discharge.

[0051] It should be noted that, in this embodiment, the first cone 21 can be a cone or a polygonal cone, etc., without limitation. At the same time, in this embodiment, an auxiliary unloading device such as a rotary scraper can also be provided in the silo 10 to simultaneously push the powder 80 through the rotary scraper. The provision of the first cone 21 can improve the operational stability of the existing auxiliary unloading device.

[0052] In a further improved embodiment, it further includes: a first vibrator 41 ; the first vibrator 41 is disposed on the silo 10 and is located on a side close to the discharge port 11 .

[0053] The first vibrator 41 may be, for example, a cavitation vibrator, which can strike the discharge port 11 of the silo 10 to assist the powder 80 in discharging, thereby preventing the powder 80 from bridging between the silo 10 and the first cone 21 and causing blockage, thereby further reducing the possibility of blockage due to material accumulation.

[0054] In application, the first vibrator 41 can be started and stopped and the vibration power can be adjusted according to actual needs.

[0055] In a more specific embodiment, it also includes: a feeder 30 and a second cone 22; the inlet end 31 of the feeder 30 is connected to the discharge port 11 of the silo 10; the outlet end 32 of the feeder 30 is connected to the unloading mechanism 50; and the sharp corner of the second cone 22 is arranged upward in the outlet end 32 of the feeder 30.

[0056] Specifically, the powder 80 falling from the discharge port 11 will enter the feeder 30, and then enter the discharge mechanism 50 after being received by the feeder 30. By arranging the second cone 22 in the feeder 30, the material diverted by the first cone 21 can be diverted again by the second cone 22, and the material receiving pressure of the discharge mechanism 50 is further reduced, which helps the discharge mechanism 50 to operate more stably.

[0057] Similarly, the second cone 22 may be a circular cone or a polygonal cone, etc. There is a gap between the second cone 22 and the discharger 30 on all sides, so that the powder 80 can fall into the discharge mechanism 50 from all sides of the second cone 22 after being diverted by the second cone 22 .

[0058] In this embodiment, the powder 80 can be dispersed by the first cone 21 and the second cone 22 to reduce the accumulation pressure of the powder 80 at the discharge port 11 and the outlet end 32, thereby reducing the possibility of material blockage.

[0059] In one embodiment, the second vibrator 42 is further included; the second vibrator 42 is disposed on the feeder 30 and is located on a side close to the outlet end 32 .

[0060] The second vibrator 42 can drive the feeder 30 to vibrate so that the powder 80 in the feeder 30 can fall more smoothly into the discharge mechanism 50 , which helps the discharge mechanism 50 to discharge quantitatively and accurately.

[0061] In a more specific embodiment, the second vibrator 42 is a horizontal vibrator, which is used to drive the feeder 30 to vibrate in the horizontal direction; Figure 1 and Figure 2 The inlet end 31 of the feeder 30 is connected to the discharge port 11 of the silo 10 through the first hose 61 .

[0062] The first hose 61 may be a rubber hose, a silicone hose, etc. The first hose 61 has a certain flexibility, which can prevent the feeder 30 from being loosened due to the vibration of the second vibrator 42 when connected with a rigid hose.

[0063] As a further improvement, see Figure 3 and Figure 4 The silo 10 is provided with an upper flange 12 at the periphery of the discharge port 11; the feeder 30 is provided with a lower flange 33 at the periphery of the inlet end 31; the upper flange 12 and the lower flange 33 are tightened and connected by a plurality of threaded suspension rods 34.

[0064] The threaded suspension rod 34 tightens the upper flange 12 and the lower flange 33 to prevent the gravity of the feeder 30 from acting on the first hose 61 , thereby protecting the first hose 61 .

[0065] In this embodiment, a plurality of lifting ears 13 are provided on the outer periphery of the upper flange 12 and the lower flange 33 ; the threaded hanging rods 34 are provided on the lifting ears 13 and are tightened by bolts to achieve a tightening connection between the upper flange 12 and the lower flange 33 .

[0066] In one embodiment, see Figure 1, and also includes: a high material level meter 71 and a low material level meter 72; the high material level meter 71 and the low material level meter 72 are arranged between the outlet end 32 of the feeder 30 and the inlet of the discharge mechanism 50, and the high material level meter 71 is arranged above the low material level meter 72; the high material level meter 71 and the low material level meter 72 are both electrically connected to the first vibrator 41 and the second vibrator 42; the high material level meter 71 is used to stop the first vibrator 41 and the second vibrator 42 when detecting that the accumulation height of the powder material 80 is higher than the high material level meter 71; the low material level meter 72 is used to start the first vibrator 41 and the second vibrator 42 when detecting that the accumulation height of the powder material 80 is lower than the low material level meter 72.

[0067] Specifically, the inlet of the discharge mechanism 50 may refer to the feed pipe 52 included in the discharge mechanism 50 described below. Figure 2 The inlet of the discharge mechanism 50 and the outlet end 32 of the discharger 30 may be connected via a second hose 62 .

[0068] As an embodiment, the high material level meter 71 and the low material level meter 72 can be arranged in the second hose 62. The high material level meter 71 and the low material level meter 72 are used to detect whether there is material in the horizontal direction. When the high material level meter 71 detects that there is material, that is, when the accumulation height of the powder 80 is higher than the high material level meter 71, the first vibrator 41 and the second vibrator 42 are stopped until the discharge mechanism 50 gradually discharges the powder 80 until the powder 80 is lower than the low material level meter 72, and then the first vibrator 41 and the second vibrator 42 are started so that the material falls smoothly into the second hose 62 under the action of vibration. According to the above cycle operation, the start and stop of the first vibrator 41 and the second vibrator 42 can be intermittently controlled, so as to reduce energy consumption while allowing the powder 80 to be discharged smoothly and avoid excessive accumulation of the powder 80 at the inlet of the discharge mechanism 50 and blockage.

[0069] In application, the side of the silo 10 close to the discharge port 11 is a conical structure with a downwardly decreasing cross-sectional area. The side of the feeder 30 close to the outlet end 32 is a conical structure with a downwardly decreasing cross-sectional area. The conical structure with a downwardly decreasing cross-sectional area helps the powder 80 to fall.

[0070] It should be noted that the second hose 62 also has a certain flexibility, which can prevent the use of a rigid tube to connect the feeder 30 and the discharge mechanism 50 and cause the tube to become loose due to the vibration of the second vibrator 42 and the discharge mechanism 50 .

[0071] Furthermore, the unloading mechanism 50 is an impeller unloading mechanism.

[0072] Specifically, if Figure 5As shown, the unloading mechanism 50 includes: a valve body 51, a feed pipe 52, an impeller rotor 53, a discharge pipe 54, a drive chain 55 and a drive motor 56. The feed pipe 52, the impeller rotor 53, the discharge pipe 54, the drive chain 55 and the drive motor 56 are all arranged on the valve body 51, and the impeller rotor 53 is rotatably arranged. The drive motor 56 is connected to the impeller rotor 53 through the drive chain 55, and is used to drive the impeller rotor 53 to rotate to realize quantitative unloading.

[0073] The feed pipe 52 is connected to the outlet end 32 of the feeder 30 and to the upper part of the impeller rotor 53 ; the discharge pipe 54 is connected to the lower part of the impeller rotor 53 .

[0074] The above are only preferred embodiments of the present application and are not intended to limit the present utility model. Although the present application has been described in detail with reference to the examples, those skilled in the art can still modify the technical solutions recorded in the aforementioned examples or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
