Description

Technical Field

[0001] This utility model relates to the field of sample bottle conveying technology, and in particular to a sample bottle pipeline conveying buffer device. Background Technology

[0002] Currently, in the intelligent fuel industry, coal samples prepared by sampling equipment are typically placed in plastic sample bottles and then transported via pneumatic conveying along closed pipelines to storage and testing equipment. This pneumatic conveying method offers advantages such as high speed, high efficiency, and flexible layout due to the airborne pipelines saving space. Pneumatic conveying uses high-pressure, high-flow-rate airflow generated by a fan to push the sample bottles to the designated location. The sample bottles travel at high speeds within the pipeline, typically reaching 8 m / s or higher. Therefore, at the sample bottle receiving station, reducing the speed of the transported sample bottles and minimizing impact is a crucial aspect of the entire pneumatic conveying system. Currently, the industry primarily uses three methods to reduce the speed of the sample bottles:

[0003] ① Pipeline pressure relief method: Install a pressure relief valve on the pipeline near the receiving station to release the pipeline pressure in advance, thereby reducing the impact when receiving sample bottles.

[0004] ② Add buffer springs or buffer pads to the gate of the receiving station to reduce the impact on the sample bottles.

[0005] ③ By reducing the diameter of the receiving station pipe and ensuring proper end sealing, back pressure is created during the bottle's descent, thereby reducing the impact on the sample bottle.

[0006] See attached document Figure 1-2 In most cases, methods ① and ② are used in combination, or methods ① and ③ are used in combination. However, the above solutions have the following drawbacks:

[0007] 1. Installing a pressure relief valve in the pipeline is a buffering method, and the installation of the pressure relief valve is crucial. If the pressure relief valve is installed on a vertical pipeline, in cases of low building height, the valve will be too close to the receiving station. If the pressure is not released in time, the sample bottle will travel to the receiving station, resulting in ineffective pressure relief and still causing a large impact. In cases of high building height, the pressure relief valve is generally installed further from the receiving station, resulting in a larger drop. The sample bottle will fall quickly after pressure relief, also causing a large impact. If the pressure relief device is installed on a horizontal pipeline with a short vertical distance, allowing the sample bottle to release pipeline pressure in the horizontal section, there is a possibility that the sample bottle will be left on the horizontal pipeline without propulsion after pressure relief, creating new problems.

[0008] 2. Adding buffer springs or buffer pads to the gate of the receiving station to buffer the sample bottles has limited energy absorption effect and cannot adapt to sample bottles of different weights. The impact also generates a lot of noise.

[0009] 3. Reducing the diameter of the receiving station pipeline and ensuring a proper end seal would create back pressure to cushion the sample bottles during their descent. However, in practice, the gap between the pipeline and the sample bottles needs strict control. A large gap prevents the formation of back pressure, while a small gap can cause the bottles to jam. Furthermore, a gate valve device is required at the end for dynamic sealing, but achieving a leak-proof seal with a gate valve is challenging. Additionally, the gate valve is prone to jamming during opening and closing, reducing product reliability. Utility Model Content

[0010] This utility model provides a sample bottle pipeline conveying buffer device to solve the problems of limited speed reduction effect, high noise or low reliability of existing coal sample bottles.

[0011] This utility model provides a sample bottle pipeline conveying buffer device, including an annular groove fixed on the pipeline, the annular groove communicating with the pipeline, and a baffle provided between the annular groove and the pipeline; a sensor is provided above the annular groove on the pipeline; the annular groove is provided with a bladder adapted to its inner contour, the bladder is recessed into the annular groove at the baffle, and the bladder is connected to a pumping mechanism, the pumping mechanism controlling the expansion and contraction of the bladder through the sensor.

[0012] Preferably, the bladder is an air bladder, the pumping mechanism is an air pump, and the air pump is connected to the air bladder via a pipe.

[0013] Preferably, an upper pipe and a lower pipe are fixed to the upper and lower ends of the annular groove, respectively, the sensor is fixed on the upper pipe, and the upper pipe and the lower pipe are fixed to the main pipe.

[0014] Preferably, the upper pipe and the lower pipe are fixed to the main pipe by pipe clamps.

[0015] Preferably, the main pipeline is connected to a pressure relief device above the sensor.

[0016] Preferably, the annular groove is composed of a top plate, a bottom plate, and a side plate, and the interface of the bladder passes through the side plate.

[0017] Preferably, the airbag is made of rubber.

[0018] Compared with existing technologies, in this invention, the pumping mechanism inputs the medium into the capsule, causing it to inflate and be ready to receive sample bottles. When a sample bottle is transported along the pipeline to the capsule, it is blocked by the portion of the capsule extending into the pipeline. The elastic capsule absorbs the impact of the sample bottle and holds it in place. At this point, a sensor detects the sample bottle and controls the pumping mechanism to reverse and extract the medium, causing the capsule to contract into the annular groove. The released sample bottle then falls smoothly into the receiving station. The capsule inflates again, preparing for the arrival of the next sample bottle. The device has a simple overall structure, is easy and quick to install, has a significant buffering effect, low noise, and high reliability. Attached Figure Description

[0031] See attached document Figure 3 This embodiment provides a sample bottle pipeline conveying buffer device, including an annular groove 1 fixed on a pipeline, the annular groove 1 installed above a receiving station, the pipeline being vertically distributed, the annular groove 1 communicating with the pipeline, and a baffle 2 provided between the annular groove 1 and the pipeline; a sensor 3 is provided above the annular groove 1 on the pipeline, the annular groove 1 having a capsule 4 adapted to its inner contour, the capsule 4 being recessed into the annular groove 1 at the baffle 2, the baffle 2 being used to confine the capsule 4 within the annular groove 1, the capsule 4 being connected to a pumping mechanism 5, the pumping mechanism 5 controlling the expansion and contraction of the capsule 4 through the sensor 3. In this utility model, refer to the attached... Figure 5 The pumping mechanism 5 delivers the medium, causing the capsule 4 to inflate. Part of the capsule 4 extends beyond the baffle 2 into the pipeline, forming a raised annular retaining ring. When the sample bottle 05 is transported to the receiving station through the pipeline, it is blocked by the annular retaining ring. The elastic capsule 4 absorbs the impact of the sample bottle 05, allowing it to be stably secured on the annular retaining ring. At this time, the sensor 3 detects the sample bottle 05 and sends a signal to the pumping mechanism 5. (Refer to Appendix) Figure 4 The pumping mechanism 5 reverses the flow of medium, causing the capsule 4 to contract into the annular groove 1, and the unrestricted sample bottle 05 gently falls into the receiving station. After the sample bottle 05 is received, the pumping mechanism 5 delivers medium again, causing the capsule 4 to inflate, preparing for the arrival of the next sample bottle 05. The device has a simple overall structure, is easy and quick to install, has a significant buffering effect, low noise, and high reliability.

[0032] In another embodiment of this utility model: the bladder 4 is an air bladder, and the pumping mechanism 5 is an air pump, which is connected to the air bladder via a pipe. The air pump is equipped with a solenoid valve group, which switches between blowing and inhaling modes by changing the conduction state of the conduit.

[0034] In another embodiment of this utility model, the upper pipe 6 and the lower pipe 7 are fixed to the main pipe 9 by pipe clamps.

[0035] In another embodiment of this utility model, a pressure relief device 8 is connected to the main pipe 9 above the sensor 3. Before the sample bottle 05 impacts the capsule 4, the pressure relief device 8 will release the pressure in the pipe in advance, thereby reducing the impact force on the capsule 4.

[0036] As another embodiment of this utility model: refer to the appendix Figure 8 The annular groove 1 is composed of a top plate 01, a bottom plate 02, and a side plate 03, as shown in the attached diagram. Figure 6-7 The interface 04 of the capsule 4 passes through the side plate 03 and connects to the tracheal connector.

[0037] As another embodiment of this utility model: the airbag is made of rubber and is processed into a circular ring with a concave square cross-section by injection molding. This cross-sectional shape is easier to install and is easier to form a convex edge when inflated, and will not block the pipe when contracted.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
