Description

Technical Field

[0001] The present invention relates to the technical field of flow-aiding devices, and in particular to a hydraulic pressure-boosting flow-aiding and anti-blocking device and a silo. Background Art

[0002] Blockage, bulging and arching in hoppers and chutes are common problems in the material flow process, which are mainly related to factors such as material properties, equipment design and operating conditions.

[0003] Blockage: refers to the phenomenon that the material cannot flow normally in the hopper or chute, resulting in blockage. This may be caused by the viscosity of the material, excessive humidity, excessive friction between particles, or poor fluidity. Blockage will cause production stagnation and affect efficiency.

[0004] Bulging: This refers to the phenomenon that the volume of materials expands in the hopper or chute due to the entry of gas or changes in the properties of the materials themselves. Bulging may cause uneven material flow or even overflow from the hopper.

[0005] Arching: This refers to the arched structure formed by the material in the hopper or chute due to the influence of gravity and friction, which prevents the material below from flowing out smoothly. Arching usually occurs in relatively dry materials with larger particles, which may cause poor discharge.

[0006] When dealing with these problems, water flow impact can be used. However, if a water pipe is directly buried in the hopper, the material will enter the inside of the water pipe and cause blockage. Therefore, the present invention proposes a hydraulic booster flow-aiding and anti-blocking device. Summary of the invention

[0015] When the piston head is away from the injection port, the working gap generated between the fitting side and the injection port is annular, and the fluid inside the fluid container is discharged from the working gap to form an annular impact flow.

[0016] As a preferred embodiment of the hydraulic booster flow-assisting and anti-blocking device of the present invention, the fluid container is provided with a fluid inlet, through which the fluid can enter the fluid container, and when the fluid enters the fluid container, the internal pressure of the fluid container increases; the fluid inlet is connected to a pressure-supply fluid pipeline, and the pressure-supply fluid pipeline is provided with an opening and closing member, and when the opening and closing member is in an open state, the pressure-supply fluid pipeline can increase the internal pressure of the fluid container to convey the fluid.

[0017] As a preferred solution of the hydraulic booster flow-aiding and anti-blocking device of the present invention, the opening and closing member is maintained in the open state for 500ms-2000ms each time.

[0018] As a preferred solution of the hydraulic booster flow-aiding and anti-blocking device of the present invention, it further includes a support frame, one end of the elastic member is connected to the support frame, and the other end of the elastic member is connected to the piston head.

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0038] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0039] Example 1

[0040] Reference Figure 1 and Figure 2 , provides a hydraulic booster flow-assisting and anti-blocking device, including a fluid container 100, which has an injection port 101; a piston head 200, which can close the injection port 101; and an elastic member 300, which is connected to the piston head 200 and can apply a first force to the piston head 200 in a direction close to the injection port 101; wherein the fluid container 100 is used to load fluid, and the fluid inside the fluid container 100 can be sprayed out through the injection port 101, and the first force applied by the elastic member 300 to the piston head 200 can make the piston head 200 press against the injection port 101.

[0041] When the internal pressure of the fluid container 100 increases, the first force can overcome the piston head 200 and the injection port 101 to generate a working gap N, and the fluid inside the fluid container 100 is discharged from the working gap N to form an impact flow; when the internal pressure of the fluid container 100 decreases, the first force can drive the piston head 200 to reset and close the injection port 101.

[0042] The first force applied by the elastic member 300 to the piston head 200 can keep the injection port 101 in a closed state before the internal pressure of the fluid container 100 reaches a certain value. Only when the internal pressure of the fluid container 100 reaches a preset value can the piston head 200 be pushed, so that a working gap N is generated between the piston head 200 and the injection port 101, thereby ensuring that under sufficient pressure, the impact flow ejected from the working gap N has sufficient impact force.

[0043] The size of the preset value can be adjusted according to different requirements by adjusting the elasticity of the elastic member 300 .

[0044] In addition, the provision of the elastic member 300 can ensure that the piston head 200 presses against the injection port 101 when not in operation, thereby closing the injection port 101 , and can prevent external impurities, such as the conveyed material, from entering the inner side of the fluid container 100 through the injection port 101 .

[0045] The hydraulic booster and flow-aiding anti-blocking device can be installed on equipment or instruments that need to be unblocked. For example, the hydraulic booster and flow-aiding anti-blocking device can be installed on a conveying pipeline, especially at a position where the conveying pipeline is prone to blockage. The fluid inside the fluid container 100 is discharged from the working gap N to form an impact flow, which can quickly unblock the position that is prone to blockage. For example, the hydraulic booster and flow-aiding anti-blocking device is installed on a feeder. The fluid inside the fluid container 100 is discharged from the working gap N to form an impact flow, which can ensure that the feeder can carry out the unloading work normally and smoothly.

[0046] Specifically, the hydraulic booster flow-aiding and anti-blocking device further includes a support frame 600 , one end of the elastic member 300 is connected to the support frame 600 , and the other end of the elastic member 300 is connected to the piston head 200 .

[0047] The purpose of setting the support frame 600 is to provide an installation position for the elastic member 300. One end of the elastic member 300 is connected to the support frame 600, and the other end applies a pulling force or a pushing force to the piston head 200 in the direction of the injection port 101, so that the piston head 200 can stably close the injection port 101. The support frame 600 can be arranged on the outside of the fluid container 100, and can also be installed inside the fluid container 100.

[0048] Furthermore, the support frame 600 is installed inside the fluid container 100 ; the piston head 200 further includes a limiting column 203 , and one end of the elastic member 300 away from the support frame 600 is connected to the limiting column 203 .

[0049] In this embodiment, the support frame 600 is installed inside the fluid container 100, the limiting column 203 on the piston head 200 extends to the inner side of the fluid container 100 through the injection port 101, the limiting column 203 is connected to the elastic member 300, and the arrangement method can be that the elastic member 300 is located between the limiting column 203 and the support frame 600, and the elastic force of the elastic member 300 is applied to the piston head 200, so that the piston head 200 can press against the injection port 101.

[0050] like Figure 3 The fluid container 100 is a tubular structure, and the support frame 600 is fixed to the inside of the fluid container 100. The support frame 600 is circular, and its radial outer wall is connected to the inside of the fluid container 100. A through hole 601 is opened at the center of the support frame 600. The limiting column 203 penetrates the support frame 600. A pressing protrusion 204 is also provided at the end of the limiting column 203. The elastic member 300 is located between the pressing protrusion 204 and the support frame 600. When the piston head 200 moves away from the injection port 101, the protrusion 203 can press the elastic member 300, so that the elastic member 300 is compressed. When the internal pressure of the fluid container 100 decreases, the elastic member 300 can push the protrusion 203, so that the limiting column 203 drives the piston head 200 to move toward the injection port 101 and reclose the injection port 101. In this embodiment, the elastic member 300 is a spring.

[0051] Furthermore, the fluid container 100 is provided with a fluid inlet 102, through which the fluid can enter the fluid container 100. When the fluid enters the fluid container 100, the internal pressure of the fluid container 100 increases. When the internal pressure of the fluid container 100 increases, the pressure acts on the piston head 200. When the pressure reaches a preset value, the piston head 200 is pushed to move, so that a working gap N is generated between the piston head 200 and the injection port 101. At this time, the fluid inside the fluid container 100 is ejected through the working gap N to form an impact flow. When the device is installed on equipment that needs to clear materials, the impact flow formed can impact the materials, thereby resolving the material blockage and ensuring the normal transportation of the materials.

[0052] The fluid inlet 102 is connected to a pressure fluid supply pipeline 400 , and the pressure fluid supply pipeline 400 is provided with an opening and closing member 500 . When the opening and closing member 500 is in an open state, the pressure fluid supply pipeline 400 can increase the internal pressure of the fluid container 100 to transport the fluid.

[0053] like Figure 6 and Figure 7A pipeline booster pump 900 is provided on the pressure supply fluid pipeline 400, which can continuously deliver the fluid to the fluid container 100. When in a non-working state, the opening and closing member 500 is in a closed state, and the fluid cannot reach the fluid container 100 through the opening and closing member 500. When in a working state, the opening and closing member 500 is converted to an open state, and the fluid reaches the fluid container 100 through the opening and closing member 500, thereby increasing the internal pressure of the fluid container 100.

[0054] Furthermore, the opening state of the opening and closing member 500 is maintained for 500ms-2000ms each time. Therefore, when the entire device is working, the opening and closing member 500 is in an intermittent opening state, that is, it enters the opening state once after being closed for a period of time. The specific cycle interval time can be set according to actual usage requirements, for example, it enters the opening state once every 10s.

[0055] Such an arrangement enables the device to release a high-pressure impact flow instantly when working to loosen the material. At the same time, because the open state is maintained for a short time, the water consumption can be reduced.

[0056] The opening and closing member 500 uses an electromagnetic valve. By setting the opening and closing time of the electromagnetic valve, the effect of cyclically opening and closing the injection port 101 can be achieved. During use, even if a small amount of material enters the inner side of the fluid container 100, the water flow will push the entered material out by opening the injection port 101 next time.

[0057] Example 2

[0058] Reference Figure 4 This embodiment is different from the first embodiment in that the piston head 200 has a fitting side 201, and the fitting side 201 can close the injection port 101 when fitting with the injection port 101.

[0059] The laminating side 201 may be a plane. When the laminating side 201 is laminating with the ejection port 101 , the laminating side 201 closes the ejection port 101 .

[0060] Specifically, the fitting side 201 has a first end 201a and a second end 201b, and the first end 201a is closer to the central axis of the piston head 200 than the second end 201b; when the fitting side 201 closes the injection port 101, the first end 201a can enter the inner side of the injection port 101.

[0061] Among them, the injection port 101 is a circular hole; the piston head 200 is provided with a truncated cone portion 202, the inclined surface of the truncated cone portion 202 constitutes a fitting side 201, the diameter of the first end portion 201a of the fitting side 201 is smaller than the aperture of the injection port 101, and the diameter of the second end portion 201b of the fitting side 201 is larger than the aperture of the injection port 101; when the piston head 200 is away from the injection port 101, the working gap N generated between the fitting side 201 and the injection port 101 is annular, and the fluid inside the fluid container 100 is discharged from the working gap N to form an annular impact flow.

[0062] The annular impact flow can increase the injection area, thereby increasing the working range of clearing materials and improving the working performance of the device. In addition, because the diameter of the second end 201b is larger than the diameter of the injection port 101, the effect of limiting the piston head 200 can be achieved. When the elastic member 300 pulls the piston head 200 toward the injection port 101, the piston head 200 can press against the injection port 101.

[0063] In addition, because a frustum portion 202 is provided on the piston head 200, and there is an inclined surface of the frustum portion 202 between the first end 201a and the second end 201b, when a working gap N is generated, the impact flow can obtain an oblique direction under the guidance of the inclined surface. When the annular impact flow obtains an oblique direction, the coverage area of ​​the entire impact flow can be improved.

[0064] The rest of the structure is the same as that of Example 1.

[0065] Example 3

[0066] Reference Figure 8 This embodiment is different from the above embodiments in that: a silo includes the above-mentioned hydraulic boosting flow-aiding and anti-blocking device, the silo is provided with a discharge port 700, and the hydraulic boosting flow-aiding and anti-blocking device is installed on the silo; when the hydraulic boosting flow-aiding and anti-blocking device is installed on the silo, the fluid container 100 does not extend into the interior of the silo, and the piston head 200 extends into the interior of the silo.

[0067] As shown in the figure, because only the injection port 101 of the fluid container 100 needs to be directed toward the interior of the silo, the impact flow ejected from the injection port 101 can impact the interior of the silo, and there is no need to arrange the entire hydraulic boosting and flow-aiding and anti-blocking device inside the silo. Therefore, when the silo uses the hydraulic boosting and flow-aiding and anti-blocking device, the hydraulic boosting and flow-aiding and anti-blocking device can reduce the internal space of the silo occupied by the hydraulic boosting and flow-aiding and anti-blocking device, and will not affect the normal operation of the silo.

[0068] In addition, when the silo adopts a hydraulic booster flow-aiding and anti-blocking device, it can also achieve a certain dust suppression effect. For example, during the coal unloading process, the water flow sprayed through the injection port 101 can effectively suppress the dust problem.

[0069] Specifically, a pre-installed hole 800 is opened on the silo, and the hydraulic booster flow-aiding and anti-blocking device is installed on the silo through the pre-installed hole 800.

[0070] The pre-installed hole 800 is an installation hole that passes through the silo wall. The end of the fluid container 100 with the injection port 101 can be directed toward the inner side of the silo through the pre-installed hole 800. At the same time, the entire hydraulic booster flow-aiding and anti-blocking device can be fixed to the silo through structures such as flanges or bolts. Different silos can choose to set pre-installed holes 800 at different positions for hydraulic booster flow-aiding and anti-blocking devices. For example, a conical silo, the position where it is prone to blockage is located at the discharge port 700. A circle of annular pre-installed holes 800 can be set at the position of the silo discharge port 700, thereby arranging a circle of annular hydraulic booster flow-aiding and anti-blocking devices at the position of the discharge port 700 to improve the effect of clearing materials.

[0071] The rest of the structure is the same as that of Example 2.
