Description

Technical Field

[0001] The utility model relates to the technical field of static weighing powder unidirectional conveying, in particular to a discharging device. Background Art

[0002] At present, during the unloading process of the ore powder weighing device for glass fiber production, a Y-type check valve is generally used to transport one-way flow-aiding gas to the weighing body, and a pneumatic vibration hammer is used to vibrate the static weighing bin wall. The positive pressure blowing of the one-way flow-aiding gas and the vibration of the static weighing bin wall by the air hammer are used to drive the powder raw materials in the static scale to slide to the discharge port for unloading.

[0003] The working principle of the Y-type check valve is as follows: the Y-type check valve relies on a section of compression spring to produce elastic deformation due to changes in external stress, so as to adjust the working position of the Y-type check valve disc, thereby changing the opening and closing working state of the Y-type check valve. The compression spring in the Y-type check valve will be repeatedly compressed and restored during its life cycle, and as time goes by, the compression spring gradually decays and produces a certain amount of plastic deformation, which will lead to the problem of compression spring stress relaxation. When the plastic deformation exceeds the yield strength of the compression spring, the compression spring basically loses its elastic force, which causes the Y-type check valve to be unable to quickly push the valve disc of the Y-type check valve onto the valve seat for sealing during the closing process of the compression spring.

[0004] However, during the static weighing feeding process, the air pressure in the static weighing is greater than that in the gas delivery pipeline, and the powder in the static weighing will flow back into the gas delivery pipeline. If the valve disc and valve seat of the check valve cannot be completely sealed, the powder medium in the gas delivery pipeline will wear the gas delivery pipeline or the valve seat of the Y-type check valve, causing environmental dust and occupational hazards. Secondly, if too much powder medium flows back, it will also block the gas delivery pipeline, resulting in the inability to output the flow-aiding gas normally, increasing the static weighing unloading time. Finally, the powder left in the gas delivery pipeline will be blown back to the static weighing by the flow-aiding gas, which will lead to inaccurate powder ratios of different glass raw material formulas, resulting in a decrease in the product yield and reduced corporate profits. Therefore, it is often necessary to manually clean the powder medium that flows back into the static weighing gas delivery pipeline. Utility Model Content

[0030] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] In order to solve the problem in the prior art that powder medium may flow back during the unloading process of the static scale, resulting in blockage of the gas delivery pipeline or affecting the original powder ratio in the static scale, thereby resulting in poor unloading efficiency of the static scale, the utility model provides a unloading device.

[0032] Please refer to Figures 1 to 9 , applying the technical solution of the utility model, the unloading device includes a unloading hopper 10, an air storage component 20 and a plurality of valve body structures 30; the unloading hopper 10 has a unloading space 11 for accommodating a powder medium and a feed port 12 and a unloading port 13 respectively connected to the unloading space 11; the air storage component 20 is arranged on the unloading hopper 10, and the air storage component 20 has an air inlet port 21 and a plurality of air outlet ports 22 that are connected to each other; the plurality of valve body structures 30 are arranged one by one corresponding to the plurality of air outlet ports 22, and the unloading hopper 10 is provided with a plurality of first air outlet ports 14 respectively connected to the unloading space 11, and the plurality of valve body structures 30 are arranged one by one corresponding to the plurality of air outlet ports 22. The first gas outlets 14 are arranged in a one-to-one correspondence with the multiple valve body structures 30, and each valve body structure 30 is respectively connected with the corresponding gas outlet port 22 and the first gas outlet 14, so that the gas flows from the gas inlet port 21 through the valve body structure 30 to the first gas outlet 14, so as to discharge the powder medium located in the discharge space 11 through the discharge port 13; wherein, a sealing component 31 is arranged in the valve body structure 30, and at least a part of the sealing component 31 can be deformably arranged along the direction from the gas outlet port 22 to the first gas outlet 14, so as to make the gas outlet port 22 and the first gas outlet 14 unidirectionally conductive or closed.

[0033] By applying the technical solution of this embodiment, the flow-aiding gas enters from the air inlet port 21 of the gas storage component 20 and flows to the multiple air outlet ports 22, and flows to the cavities of the multiple valve body structures 30 accordingly. Since the gas pressure of the flow-aiding gas increases rapidly after flowing into the cavity, at least part of the sealing component 31 in the valve body structure 30 is deformed in the direction from the air outlet port 22 to the first air outlet 14, thereby making the air outlet port 22 to the first air outlet 14 unidirectional, so that the flow-aiding gas flows from the valve body structure 30 to the first air outlet 14, so as to blow the powder medium in the discharge space 11 to the discharge port 13 and The powder medium is discharged, and the powder medium cannot flow from the first gas outlet 14 to the gas outlet port 22, thereby solving the problem in the prior art that the powder medium will flow back during the unloading process of the static scale, resulting in blockage of the gas delivery pipeline or affecting the original powder ratio in the static scale, thereby resulting in poor unloading efficiency of the static scale; at the same time, it can greatly extend the service life of the valve body structure 30, effectively reduce the maintenance tasks caused by the blockage of the gas delivery pipeline or the wear of the gas delivery pipeline due to the backflow of the powder medium, increase the effective working time of the static scale, reduce the risk of occupational hazards, speed up the unloading speed of the powder medium of the static scale, and greatly improve the batching efficiency of the static scale.

[0034] In this embodiment, the sealing component 31 is an elastic rubber sheet.

[0035] like Figures 4 to 8As shown, the valve body structure 30 includes a shell body 32 and a sealing assembly 33; wherein the shell body 32 has a ventilation cavity 320 and an air inlet 321 and a second air outlet 322 respectively connected to the ventilation cavity 320, the air inlet 321 is connected to the air outlet port 22, and the second air outlet 322 is connected to the first air outlet 14; the sealing assembly 33 includes a sealing component 31, and the sealing assembly 33 is arranged in the shell body 32 to divide the ventilation cavity 320 into a first cavity 3201 and a second cavity 3202, the first cavity 3201 is connected to the air inlet 321, and the second cavity 3202 is connected to the second air outlet 322. In this way, the above arrangement makes it possible for the flow-aiding gas flowing out of the gas outlet port 22 of the gas storage component 20 to flow into the first cavity 3201 of the valve body structure 30 from the gas inlet 321, and the gas pressure in the first cavity 3201 will increase rapidly, thereby causing at least a portion of the sealing component 31 to deform in the direction from the first cavity 3201 to the second cavity 3202, so that the first cavity 3201 and the second cavity 3202 are unidirectionally connected from the first cavity 3201 to the second cavity 3202, so that The flow-aiding gas delivered by the first gas outlet 14 is prevented from flowing back into the first cavity 3201 through the second cavity 3202 from the first gas outlet 14 during the discharge process of the powder medium in the discharge hopper 10, thereby greatly enhancing the reverse airtightness of the valve body structure 30. In this process, the sealing component 31 will only produce elastic deformation along a fixed direction (from the first cavity 3201 to the second cavity 3202) only when the flow-aiding gas is continuously output.

[0036] In this embodiment, the case body 32 includes a first shell 323 and a second shell 324 that are detachably connected.

[0037] Specifically, the sealing assembly 33 includes a mounting seat 34, the mounting seat 34 includes a mounting plate 340 and a guide component 341 arranged on the mounting plate 340 on a side close to the first cavity 3201, a plurality of guide holes 3410 are arranged on the guide component 341, and the plurality of guide holes 3410 are respectively connected to the first cavity 3201 and the second cavity 3202, and the sealing component 31 is arranged on a side of the mounting seat 34 close to the second cavity 3202, and the sealing component 31 is in sealing contact with the plurality of guide holes 3410, so that after the gas entering from the air inlet 321 flows to the plurality of guide holes 3410 through the first cavity 3201, at least a portion of the sealing component 31 is deformed in the direction from the first cavity 3201 to the second cavity 3202, so that the first cavity 3201, the plurality of guide holes 3410 and the second cavity 3202 are unidirectionally conductive. With the above arrangement, the sealing component 31 has two states of opening or blocking the multiple guide holes 3410, so that when the flow-aiding gas flowing out from the gas outlet port 22 of the gas storage component 20 flows into the first cavity 3201 of the valve body structure 30 through the gas inlet 321, the gas pressure in the first cavity 3201 will increase rapidly, causing the sealing component 31 to deform in the direction from the first cavity 3201 to the second cavity 3202 to open the multiple guide holes 3410, thereby allowing the first cavity 3201 and the second cavity 3202 to be connected through the multiple guide holes 3410.

[0038] Specifically, the sealing assembly 33 further includes a limiting component 35, which is arranged on a side of the mounting seat 34 close to the second cavity 3202 and connected to the sealing component 31, so as to limit the sealing component 31 when at least a portion of the sealing component 31 is deformed in the direction from the first cavity 3201 to the second cavity 3202. In this way, the above arrangement enables at least a portion of the sealing component 31 to contact the limiting component 35 when the sealing component 31 is deformed in the direction from the first cavity 3201 to the second cavity 3202. At this time, the sealing component 31 has fully opened a plurality of guide holes 3410, and the limiting component 35 is used to resist the sealing component 31, so as to prevent the sealing component 31 from continuously deforming under the gas pressure in the first cavity 3201.

[0039] Preferably, the limiting component 35 is a conical structure, the limiting component 35 has a first end surface at one end facing the first cavity 3201, and has a second end surface at one end facing the second cavity 3202, and the cross-sectional area of ​​the first end surface is smaller than the cross-sectional area of ​​the second end surface. In this way, the conical limiting component 35 ensures that the sealing component 31 will not deform excessively, and the sealing component 31 always opens or blocks multiple backflow holes within the optimal elastic deformation range.

[0040] Furthermore, a first connecting hole 350 is provided on the limiting component 35, a second connecting hole 310 is provided on the sealing component 31, and a third connecting hole 3411 is provided on the guide component 341, so that the first connecting hole 350, the second connecting hole 310 and the third connecting hole 3411 are sequentially penetrated through the connecting components, so that the guide component 341, the sealing component 31 and the limiting component 35 are relatively fixedly arranged.

[0041] In this embodiment, the first connecting hole 350, the second connecting hole 310 and the third connecting hole 3411 are all internal threaded holes, and the connecting components are threaded rods. The threaded rods cooperate with nuts to relatively fix the guide component 341, the sealing component 31 and the limiting component 35.

[0042] Preferably, the sealing component 31 is a conical structure, and the end of the sealing component 31 facing the first cavity 3201 has a fifth end face, and the end of the sealing component 31 facing the second cavity 3202 has a sixth end face; the cross-sectional area of ​​the fifth end face is smaller than the cross-sectional area of ​​the sixth end face. In this way, the above-mentioned arrangement greatly reduces the pressure-bearing time of the sealing component 31 with a conical structure, and the accumulated amount of plastic deformation is relatively slow. At the same time, the force-bearing area of ​​the sealing component 31 located on the sixth end face is large, which can effectively disperse the impact force of the powder medium carried by the reflux gas on the mounting seat 34, thereby greatly extending the service life of the valve body structure 30.

[0043] Preferably, the flow guide component 341 is a conical structure, and the end of the flow guide component 341 facing the first cavity 3201 has a third end face, and the end of the flow guide component 341 facing the second cavity 3202 has a fourth end face; the cross-sectional area of ​​the third end face is smaller than the cross-sectional area of ​​the fourth end face. In this way, the above arrangement enables the sealing component 31 with a conical structure to be matched and connected with the flow guide component 341 with a conical structure to block the multiple flow guide holes 3410 located on the third end face.

[0044] In this embodiment, the sealing component 31 is made of elastic material.

[0045] Optionally, the mounting plate 340 and the flow guide component 341 are an integrated structure.

[0046] Specifically, the gas storage component 20 is an annular structure, and the gas storage component 20 is sleeved on the discharge hopper 10 .

The above arrangement outputs flow-aiding gas through each ventilation pipe 42 connected to the first gas outlet 14 in a horizontal direction, which can accelerate the powder medium in the unloading space 11 to gather at the unloading port 13 and discharge it from the unloading port 13.

[0049] In this embodiment, the joint component 40 is a female thread joint; and the pipe diameter of the ventilation pipe 42 can be adjusted accordingly according to the required pressure of the output gas.

[0050] Preferably, a plurality of first gas outlets 14 are respectively arranged along the spiral direction on the discharge hopper 10. In this way, the above arrangement enables each valve body structure 30 to basically output flow-aiding gas to the static scale at the same time, and the output flow-aiding gas will increase the collapse angle of the powder medium in the static scale, destroy the stable structure of the powder medium in the static scale, and accelerate the powder medium to gather rapidly at the discharge port 13 of the static scale, and the gas remaining in the static scale generates a slight positive pressure to act on the powder medium at the discharge port 13 of the static scale, thereby improving the unloading operation efficiency of the static scale.

[0051] Specifically, the unloading device further includes a first control valve 50 and a second control valve 60, which are connected to the air inlet port 21 in sequence to adjust the gas flow entering the gas storage component 20.

[0055] Furthermore, the data processing and storage module can also adjust the working status data of the pneumatic ball valve 120, the pneumatic angle seat valve 130, the pneumatic vibratory hammer 140, and the pneumatic butterfly valve 150, and quickly display them on the human-computer interaction touch screen of the PLC control station 110 through the command input and display module. On-site operators can input adjustment commands through the touch screen to adjust the working status of the pneumatic ball valve 120, the pneumatic angle seat valve 130, the pneumatic vibratory hammer 140, and the pneumatic butterfly valve 150.

[0056] Preferably, the valve control devices of the pneumatic ball valve 120, the pneumatic angle seat valve 130, the pneumatic vibration hammer 140, and the pneumatic butterfly valve 150 further include a switch, an optical fiber network, an optical fiber transceiver 100, and an operator station 80. The PLC control station 110, the switch, the optical fiber network, and the optical fiber transceiver 100 are sequentially connected through a signal transmission line.
