Description

Technical Field

[0001] The utility model belongs to the technical field of workshop waste gas collection and treatment, and particularly relates to a magnetic transparent curtain device for enhancing waste gas collection in a silo. Background Technique

[0002] In the workshop for producing cable materials, the waste gas emission exceeds the standard. Along with the processes of feeding, stirring, jittering and cooling, a large amount of VOCs waste gas is generated. Especially after being kneaded by a kneader, fed by a feeding machine and extruded by a screw machine and entering the cooling process, since the hot cable materials are in full contact with the cooling air flow, the cable materials will cool down rapidly, generating a large amount of VOCs waste gas. At the current stage, in order to remove the VOCs waste gas generated by the process, dust removal equipment + pipelines and gas collection hoods are often used. The gas collection hood is mainly used to centrally collect VOCs waste gas, and the pipelines transport the collected waste gas to the dust removal equipment for adsorption and removal. The exhaust gas of the dust removal equipment is incorporated into the VOCS pipeline system, and the gas collection hood has an independent axial flow fan.

[0003] However, due to the diffusion of VOCs waste gas, the VOCS emission from the cooling silo cannot be sucked away in time, which is the main reason for the low treatment efficiency of VOCS in the workshop. The flow rate of the cooling fan under the cooling silo is 1960m 3 / h and the rotation speed is 2900r / min. The flow rate of the axial flow fan of the upper gas collection hood is 980 - 1988m 3 / h and the rotation speed is 1400r / min. The generated VOCs cannot be sucked away in time and completely, affecting the overall treatment efficiency of VOCS.

[0004] Therefore, how to improve the efficiency of collecting VOCs in the existing cable material cooling process has become the main problem in the environment of the cable material production workshop. Content of the Utility Model

[0005] The purpose of the utility model is to provide a magnetic transparent curtain device for enhancing waste gas collection in a silo, which can effectively improve the workshop environment and enhance the collection efficiency of VOCs.

[0006] In order to solve the above technical problems, the technical scheme adopted by the utility model is as follows:

[0007] A magnetic transparent curtain device for enhancing waste gas collection in a silo includes a cable material cooling silo and a magnetic transparent curtain arranged around the cable material cooling silo. The magnetic transparent curtain includes a ferromagnetic frame, a transparent curtain, a soft magnetic seal a and a soft magnetic seal b. The top end of the transparent curtain is fixedly connected to the ferromagnetic frame, the side of the transparent curtain is provided with the soft magnetic seal a, and the bottom of the transparent curtain is provided with the soft magnetic seal b.

[0008] Furthermore, the top edge of the transparent curtain is fixedly connected to the ferromagnetic frame by screws and / or glue.

[0009] Further, a soft magnetic seal a is provided on the side of the transparent curtain; a soft magnetic seal b is provided on the bottom of the transparent curtain.

[0010] Further, multiple groups of the transparent curtains are arranged side by side on each side of the ferromagnetic frame. Each group of transparent curtains is magnetically connected by the soft magnetic seal a, and the bottom of each group of transparent curtains is magnetically connected to the ferromagnetic frame by the soft magnetic seal b.

[0011] Further, the soft magnetic seal a is adhesively bonded to the transparent curtain; there is a groove structure between the soft magnetic seal a and the transparent curtain, and a mortise and tenon structure is formed by the grooves between the soft magnetic seals a on the sides of every two transparent curtains.

[0012] Further, the material of the transparent curtain is PVC plastic; the materials of both the soft magnetic seal a and the soft magnetic seal b are rubber magnet.

[0013] Further, sealing films are provided on both the top and bottom surfaces of the magnetically attracted transparent curtain. The sealing film on the top surface is also provided with through holes through which a cable material input pipe and an exhaust gas collection pipe a can pass.

[0014] Further, the cable material cooling bin includes a gas collection hood and an exhaust gas collection pipe b.

[0015] Further, the overall shape of the gas collection hood is trumpet-shaped and is arranged at the bottom of the upper part of the cooling material bin.

[0016] Further, the exhaust gas collection pipe b is provided on the transparent curtain on the side of the magnetically attracted transparent curtain. Through holes are provided on the transparent curtain, the aperture of the through holes is slightly larger than the diameter of the exhaust gas collection pipe b, and the contact part between the through holes and the exhaust gas collection pipe b is filled with glue.

[0017] Compared with the prior art, the utility model has the following advantages:

[0018] (1) The magnetically attracted transparent curtain adopted by the utility model can enclose the entire cooling material bin to form a sealed space. During normal operation, the transparent curtain has an inward acting force, and the negative pressure is obvious, which improves the recovery of exhaust gas by the collection hood.

[0019] (2) Aiming at the problem that the VOCs emission from the cooling material bin cannot be sucked away in time, resulting in low collection and treatment efficiency of VOCs in the workshop, the utility model uses a magnetically attracted transparent curtain to cover the cooling material bin to increase the sealing performance, and thus can well adapt to the axial flow fan on the collection hood to increase the flow rate, form a negative pressure, accelerate the cooling rate and improve the exhaust gas collection efficiency at the same time.

Detailed implementation manners

[0027] The following combines specific embodiments to further clarify the present utility model. The embodiments are implemented on the premise of the technical solution of the present utility model. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model.

[0028] As Figure 1 , Figure 2 , Figure 5 and Figure 6 shown, a magnetic adsorption transparent curtain device for enhancing waste gas collection in a bin includes a magnetic adsorption transparent curtain and a cable material cooling bin. The cable material cooling bin is arranged inside the transparent curtain and is connected to the magnetic adsorption transparent curtain through a pipeline.

[0029] The magnetic adsorption transparent curtain includes a ferromagnetic frame 1, a transparent curtain 2, a soft magnetic seal a 3, and a soft magnetic seal b 12. The ferromagnetic frame 1 is a cubic frame built by iron or iron alloy metal, which can be fixedly installed on the periphery of the entire cable material cooling bin and maintain the stability of the overall structure. The top of the ferromagnetic frame 1 is fixedly connected to the transparent curtain 2 by screws or glue. The transparent curtain 2 is arranged side by side on each side of the ferromagnetic frame 1. Soft magnetic seals (soft magnetic seal a 3 is arranged on both sides of the transparent curtain 2, and soft magnetic seal b 12 is arranged on the bottom edge of the transparent curtain 2) are arranged on both side edges and the bottom edge of the transparent curtain 2. Through the magnetic attraction between the soft magnetic seals a 3, when the transparent curtain 2 hangs naturally, the soft magnetic seals a 3 can attract each other automatically, thereby completing the closing between the transparent curtains 2; As Figure 4As shown, the soft magnetic seal b12 at the bottom edge of the single transparent curtain 2 can also attract the bottom end of the ferromagnetic frame 1 when hanging naturally, further improving the closing and sealing performance of the entire magnetic transparent curtain.

[0030] As Figure 3 shown, the shape of the soft magnetic seal a3 provided on the side of the transparent curtain 2 is stepped. The shorter side is evenly bonded to the side of the transparent curtain 2 with glue, thus forming a structure with a middle groove. A good mortise and tenon structure can be formed between the soft magnetic seals a3 on the sides of every two transparent curtains 2 through the grooves. On the basis of the magnetic attraction of the soft magnetic seals a3, the mortise and tenon structure can further improve the closing and binding force between the soft magnetic seals a3, and thus effectively improve the sealing ability between the transparent curtains 2. The materials of both the soft magnetic seal a3 and the soft magnetic seal b12 are rubber magnets, which have certain flexibility on the basis of having magnetism, can undergo temporary deformation under the interference of external forces, and can return to their original state when the external forces disappear. While effectively facilitating the opening and closing of the transparent curtain 2, it greatly improves the service life of the entire transparent curtain 2.

[0031] The material of the transparent curtain 2 is PVC plastic, which has high transparency and environmental protection. It can provide good line-of-sight permeability, facilitate observing the situation inside the curtain at any time, and can also resist certain physical wear and chemical corrosion. After being used for a long time, it still maintains good performance and appearance, improving the durability of the entire transparent curtain.

[0032] Sealing films are provided on both the top side and the bottom side of the magnetic transparent curtain. The sealing film on the top side is provided with through holes, which can ensure the normal passing of the cable material input pipe 4 and the waste gas collection pipe a5 while improving the airtightness of the entire magnetic transparent curtain.

[0033] The cable material cooling bin includes: a cable material input pipe 4, an exhaust gas collection pipe a 5, the upper part 6 of the cooling bin, a gas collection hood 7, an exhaust gas collection pipe b 8, the lower part 9 of the cooling bin, a cooling air duct 10, and a cable material output pipe 11. The cable material input pipe 4 and the exhaust gas collection pipe a 5 are arranged at the top of the upper part 6 of the cooling bin, and the gas collection hood 7 is arranged at the bottom of the upper part 6 of the cooling bin; the cable material input pipe 4 mainly conveys the cable material produced in the previous process into the cooling bin for the cooling process in the cooling bin; the exhaust gas collection pipe a 5 is used to collect the exhaust gas generated by cooling the cable material. The gas collection hood 7 is overall in a horn shape with the larger opening facing downwards, which is beneficial to the collection of gas. The exhaust gas collection pipe b 8 is arranged on the magnetic adsorption transparent curtain, specifically on a certain transparent curtain 2 on the side of the magnetic adsorption transparent curtain. The transparent curtain 2 is provided with through holes (the aperture is slightly larger than the diameter of the exhaust gas collection pipe b 8), and the contact part between the through holes and the exhaust gas collection pipe b 8 is filled with glue to improve the airtightness of the whole device. The exhaust gas collection pipe b 8 is mainly used to collect the gas that the exhaust gas collection pipe a 5 fails to collect. Since the magnetic adsorption transparent curtain is located around the cooling bin, the gas that the exhaust gas collection pipe a 5 fails to collect will be enclosed in the space by the magnetic adsorption transparent curtain. At this time, the exhaust gas can be conveyed through the exhaust gas collection pipe b 8, so as to keep the enclosed space in a negative pressure state all the time.

[0034] The cooling air duct 10 and the cable material output pipe 11 are arranged at the bottom end of the lower part 9 of the cooling bin. When the cable material input pipe 4 conveys the cable material particles prepared in the previous process to the upper part 6 of the cooling bin, the cable material particles fall into the lower part 9 of the cooling bin under the continuous action of gravity. Open the valve on the cooling air duct 10. The cooling air duct 10 is connected with a cooling fan, and the cooling air duct 10 conveys cooling gas to cool the cable material; the cooled cable material finally flows out of the cable material cooling bin through the cable material output pipe 11, completing the cooling process of the cable material.

[0035] The working principle of the utility model is as follows: a magnetic transparent curtain is installed around a cable material cooling bin; a ferromagnetic frame 1 is a cubic frame constructed of iron or ferroalloy metal, which can be fixedly installed on the periphery of the entire cable material cooling bin and maintain the stability of the overall structure; the transparent curtain 2 naturally droops under the action of gravity; the soft magnetic seal a 3 absorbs two adjacent transparent curtains 2 through magnetic attraction; the mortise and tenon structure of the soft magnetic seal a 3 further enhances the bonding ability of the two transparent curtains 2; the soft magnetic seal b 12 fits the bottom of each transparent curtain 2 with the ferromagnetic frame 1 through magnetic action, thereby forming a closed environment together. When the cable material particles are transported from the cable material input pipe 4 to the cable material cooling bin, the valve on the cooling air duct 10 is opened, and the cold air is pumped from the cooling air duct 10 to the cable material cooling bin. The cable material particles first reach the upper part 6 of the cooling bin. Under the continuous action of gravity, the cable material particles will fall vertically downward into the lower part 9 of the cooling bin. At this time, the cold air pumped to the cable material cooling bin through the cooling air duct 10 will continue to contact the cable material particles upward, quickly absorb and take away the heat on the cable material particles, and achieve rapid cooling of the cable material particles. The cooled cable material will flow out of the cable material cooling bin through the cable material output pipe 11 and enter the subsequent process. Due to the sealing effect of the magnetic transparent curtain, part of the wind body after absorbing the heat continues to reach the upper part 6 of the cooling bin and is discharged through the waste gas collection pipe a 5; the other part will be discharged from the cooling bin through the waste gas collection pipe b 8, thereby ensuring the efficient centralized collection and timely discharge of the waste gas from the cooling bin, always maintaining the negative pressure environment in the entire device, and avoiding the waste gas from leaking into the surrounding environment of the workshop to cause pollution.
