[0030] Embodiments

[0031] Reference Figures 1-5 The present embodiment provides a degassing air lock, which comprises a casing 110 and a degassing part 120. The casing 110 comprises a discharge bin 111. The degassing part 120 comprises a degassing box arranged on the side wall of the discharge bin 111. A gas pipe joint 121 is arranged on the degassing box, which is used to connect an air extraction device (not shown in the figure).

[0032] In the present embodiment, by adding the degassing part 120 which can be docked with the air extraction device, the useful gas in the material transported in the discharge bin 111 can be extracted and recovered. The degassing box can form an air extraction space independent of the discharge bin 111, avoiding the air extraction device directly extracting air from the discharge bin 111, reducing the risk of mistakenly adsorbing the material. When the gas pipe joint 121 is connected to the air extraction device, the useful gas entrained in the material is sucked into the degassing box under the action of the pressure difference, and then transported to the subsequent gas treatment and recovery system through the air extraction pipeline. The material after degassing continues to complete the transportation process in the discharge bin 111, finally achieving the purpose of energy saving and emission reduction.

[0033] It should be noted that a square opening, a circular opening or an elliptical opening can be provided on the side wall of the discharge bin 111. The size and shape of the opening should be determined comprehensively according to the specifications of the air lock, the expected amount of gas to be processed, the characteristics of the material and other factors. The selection of the opening position is also very important, which should ensure that it is located at a position where the gas distribution in the material is relatively uniform and easy to connect with the degassing box. Then the degassing box is installed. The degassing box should have good sealing performance to prevent external air from mixing, and its internal structure should be designed reasonably to improve the gas collection efficiency. The size of the adsorption force of the air extraction device can be set according to the properties of the material. If the self-gravity of the material is large, the adsorption force can be increased to improve the degassing effect. Conversely, if the self-gravity of the material is small, the adsorption force can be reduced to reduce the risk of adsorbing the material.

[0034] As an optional implementation, the isolation net 130 is arranged in the degassing box.

[0035] In the embodiment, the risk of material entering the degassing box is minimized by the isolation net 130, so that the adsorption of the air extraction device is improved, that is, the degassing effect is ensured, and the material unloading is not affected.

[0036] As an optional implementation, the isolation net 130 includes a net cylinder 131 and an arc-shaped filter screen 132. The net cylinder 131 is arranged on the inner wall of the degassing box. The arc-shaped filter screen 132 is connected to one end of the net cylinder 131 close to the unloading bin 111.

[0037] In the embodiment, the isolation net 130 is designed in a cylindrical structure, and the net cylinder 131 can be directly arranged on the inner wall of the degassing box without the need for additional fasteners for fixation, facilitating quick assembly. At the same time, the arc-shaped filter screen 132 effectively blocks the material from entering the degassing box, achieving two purposes at once.

[0038] As an optional implementation, the arc surface of the arc-shaped filter screen 132 and the arc surface of the inner wall of the unloading bin 111 are spliced into a circular arc, so that the arc-shaped filter screen 132 and the inner wall of the unloading bin 111 do not form a gap, avoiding that part of the material is blocked in the gap.

[0039] As an optional implementation, the degassing box includes a box body 122 and a cover plate 123. The box body 122 is a through structure, and the box body 122 is integrally connected to the outer wall of the unloading bin 111. The cover plate 123 is detachably connected to the side of the box body 122 away from the unloading bin 111, and the air pipe joint 121 is arranged on the cover plate 123.

[0040] In the embodiment, the cover plate 123 is detachably connected to the box body 122 by screws, facilitating assembly and periodic disassembly of the cover plate 123 to remove the filter screen 132 and clean the material accumulated on the arc-shaped filter screen 132, preventing the arc-shaped filter screen 132 from being blocked and reducing the adsorption of useful gas in the material.

[0041] It should be noted that the box body 122 can be integrally connected to the side wall of the unloading bin 111 by welding, which is structurally robust and stable.

[0042] As an optional implementation, the unloading bin 111 is provided with an unloading assembly 140. The unloading assembly 140 includes a rotating shaft 141 and a plurality of blades 142. The rotating shaft 141 is movably connected to the inside of the unloading bin 111. The plurality of blades 142 are arranged in a ring array on the rotating shaft 141 around the axis of the rotating shaft 141, and the ends of the blades 142 are attached to the inner wall of the unloading bin 111. Here, the ends of the blades 142 can also be attached to the arc-shaped filter screen 132.

[0043] In the embodiment, when the material enters the discharge bin 111, the quantified material is contained in the space formed by the adjacent blades 142, and the rotation of the rotating shaft 141 can drive the material in the space to rotate from the top to the bottom, and the material can be discharged from the lower discharge port under the action of gravity, thereby realizing the function of quantitative discharge.

[0044] As an optional embodiment, at least two material distribution plates 150 are connected between the adjacent blades 142, which can distribute the material in the space between the adjacent blades 142, preventing the material from being too concentrated and accumulated, and affecting the discharge.

[0045] As an optional embodiment, the rotating shaft 141 is respectively connected with a bearing seat 160 and a driving motor 170 at both ends, and the bearing seat 160 and the driving motor 170 are respectively arranged on the two outer side walls of the discharge bin 111. The driving motor 170 can drive the rotating shaft 141 to rotate, and the bearing seat 160 can support and cooperate with the rotation of the rotating shaft 141.

[0046] It should be noted that the driving motor 170 can be a stepping motor or a servo motor. The stepping motor is an electric motor that converts electrical pulse signals into corresponding angular displacement or linear displacement. Every input pulse signal, the rotor rotates an angle or moves forward one step, and the output angular displacement or linear displacement is proportional to the input pulse number, and the rotation speed is proportional to the pulse frequency. The servo motor can control the speed, and the position accuracy is very accurate, and can convert the voltage signal into torque and speed to drive the control object. The above two motors can meet the use requirement of accurate control of rotation speed.

[0047] As an optional embodiment, the machine shell 110 further comprises a feeding hopper 112 and a discharge hopper 113, the feeding hopper 112 is connected to the top of the discharge bin 111, and the discharge hopper 113 is connected to the bottom of the discharge bin 111. The material can enter the discharge bin 111 from the feeding hopper 112, and finally quantitatively discharged from the discharge hopper 113.

[0048] As an optional embodiment, the other end of the feeding hopper 112 and the discharge hopper 113 is provided with a connecting flange 114. The connecting flange 114 can assemble the entire air lock to the equipment conveying the material, and has strong versatility.

[0049] It should be noted that the connecting flange 114 can be integrally formed with the feeding hopper 112 and the discharge hopper 113 by welding, which is firm and not easy to loosen, and meets the use requirement.

[0050] The above is only a preferred embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
