Description

TECHNICAL FIELD

[0001] The utility model relates to cone feeding technology field especially relates to connecting sealing mechanism and its conical feeding device. BACKGROUND

[0002] In industrial production, the conical silo is generally used as a buffer silo and a feeding device to ensure the continuity of industrial production. In practical application, the traditional conical silo feeding device has the following defects when in use: high-density large-particle materials can slide from the feeding port by their own gravity, but the powder with small specific gravity is easy to be hardened and adhered to the wall of the silo, and is not easy to slide down, especially when the powder with high water content is fed, it is easy to harden and block the feeding port, which seriously hinders the continuity of feeding, and the operating personnel need to carry out the unblocking operation for a long time, which reduces the operating efficiency. At the same time, due to the direct connection between the existing conical feeding device and the barrel, the sealing effect is poor, which is easy to cause the material to enter the conical feeding device and damage the device. SUMMARY

[0003] To solve the above technical problems, one of the technical solutions adopted by the utility model is: a connecting sealing mechanism, which is used to place the barrel at the discharge port of the conical feeding device to prevent the material in the barrel from entering the device and avoid damaging the device, the mechanism comprises:

[0004] A dustproof sealing unit 1 is used to prevent dust from entering the inside of the conical feeding device, and the dustproof sealing unit 1 is installed on the upper end edge of the discharge port of the conical feeding device.

[0005] A clamping unit 2 is installed on the conical feeding device, and the inner surface thereof is in contact with the dustproof sealing unit 1.

[0006] An annular sealing unit 3 is tightly attached to the outer surface of the clamping unit 2 to complete the sealing between the barrel and the discharge port of the conical feeding device, and the annular sealing unit 3 is installed at the lower end of the barrel.

[0007] Further, the dustproof sealing unit 1 is a sealing rubber ring.

[0008] Further, the clamping unit 2 is an elastic metal ring.

[0009] Further, one end of the clamping unit 2 is installed on the barrel lower end support frame of the conical feeding device.

[0010] Further, the annular sealing unit 3 comprises:

[0011] A mounting ring 301 is installed at the lower end of the barrel.

[0012] A sealing ring 302 is installed in the mounting ring 301.

[0013] The sealing ring 302 abuts against the outer surface of the snap-fit ​​unit 2.

[0014] Another technical solution adopted by this utility model is: a conical feeding device, which includes the above-mentioned connecting and sealing mechanism.

[0015] The advantages and positive effects of this utility model are as follows: The material cylinder is hoisted to the discharge port of the conical feeding device using an external hoisting device. The sealing ring 302 abuts against the outer surface of the snap-fit ​​unit 2. Since the snap-fit ​​unit 2 is an elastic metal ring, it further compresses the dustproof sealing unit 1, thereby achieving a double seal between the discharge port and the material cylinder. This prevents materials and dust from entering the conical feeding device, protecting the device. Attached Figure Description

[0019] To better understand this utility model, the present utility model will be further described below with reference to specific embodiments and accompanying drawings.

[0020] Example 1

[0021] like Figure 2 As shown, a sealing mechanism is connected. This mechanism is used to place the material cylinder at the discharge port of the conical feeder to prevent material inside the cylinder from entering the device and thus avoiding damage. This mechanism includes:

[0022] Dustproof sealing unit 1 is used to prevent dust from entering the inside of the conical feeding device; the dustproof sealing unit 1 is installed on the upper edge of the discharge port of the conical feeding device;

[0023] The snap-fit ​​unit 2 is installed on the conical feeding device, and its inner surface is in contact with the dustproof sealing unit 1.

[0024] The annular sealing unit 3 fits tightly against the outer surface of the snap-fit ​​unit 2 to seal the material cylinder and the discharge port of the conical feeding device; the annular sealing unit 3 is installed at the lower end of the material cylinder.

[0025] Specifically, the annular sealing unit 3 includes:

[0026] Mounting ring 301 is installed at the lower end of the material cylinder;

[0027] The sealing ring 302 is installed inside the mounting ring 301;

[0028] The sealing ring 302 abuts against the outer surface of the snap-fit ​​unit 2.

[0029] Furthermore, the dustproof sealing unit 1 is a sealing rubber ring.

[0030] Furthermore, the snap-fit ​​unit 2 is an elastic metal ring.

[0031] Furthermore, one end of the snap-fit ​​unit 2 is mounted on the lower support frame of the feed cylinder of the conical feeder.

[0032] Furthermore, the annular sealing unit 3 includes:

[0033] Mounting ring 301 is installed at the lower end of the material cylinder;

[0034] The sealing ring 302 is installed inside the mounting ring 301;

[0035] The sealing ring 302 abuts against the outer surface of the snap-fit ​​unit 2.

[0036] Its working process is as follows: The material cylinder is hoisted to the discharge port of the conical feeding device using external hoisting equipment. The sealing ring 302 abuts against the outer surface of the snap-fit ​​unit 2. Since the snap-fit ​​unit 2 is an elastic metal ring, it further compresses the dustproof sealing unit 1, thereby achieving a double seal between the discharge port and the material cylinder. This prevents materials and dust from entering the conical feeding device, protecting the device.
