Description

Technical Field

[0001] The invention relates to a sealing connection mechanism, in particular to a intensive bus duct sealing connection mechanism of a reconstituted tobacco joint workshop. Background Art

[0002] The front-end process workshop in the reconstituted tobacco workshop is mainly used for extraction and pulping of tobacco leaves, which is prone to produce a large amount of water vapor, dust, and wall debris. Compared with other working conditions, the environment is more severe. Four sets of intensive bus ducts are used in the front-end process workshop of tobacco leaf processing. The span length of a single set of intensive bus ducts exceeds 200 meters. The insulation level decreases year by year due to the influence of moisture, dust, wall debris, etc. in perennial production. The bus duct will short-circuit when it is damp, leading to fire accidents. It poses a great hidden danger to the stable operation of the front-end process workshop of tobacco leaf processing. The bus duct is a non-standard part. Once a short-circuit fault occurs, it can only be customized. The procurement and production cycle is long, which has a serious impact on production and is a major safety hazard. Therefore, there is an urgent need for a intensive bus duct sealing connection mechanism that is suitable for the working conditions of the front-end process workshop of tobacco leaf processing.

[0005] A sealing layer structure is arranged at the gap between the dense bus duct and the connector, and the sealing layer structure includes a sealing glue layer, tin foil aluminum sheet and temperature indicating wax paper. The sealing glue layer is formed after the sealant is filled in the gap between the dense bus duct and the connector, the tin foil aluminum sheet is wrapped around the outside of the gap between the dense bus duct and the connector, the tin foil aluminum sheet is on the outside of the sealing glue layer, and the temperature indicating wax paper is pasted on the outside of the tin foil aluminum sheet.

[0006] In order to more clearly understand the technical content of the present invention, the intensive bus duct sealing connection mechanism of the reconstituted tobacco joint workshop is referred to as the present sealing connection mechanism below.

[0007] As a preferred embodiment of the sealing connection mechanism, the connector includes a clamping bolt, two side guard plates and a plurality of conductive components;

[0008] A number of conductive components correspond one by one to a number of copper bars of the intensive busbar. The conductive components include a first insulating plate, a second insulating plate, a first conductive plate and a second conductive plate. The first insulating plate and the second insulating plate are arranged at intervals. The first conductive plate is fixedly connected to the first insulating plate, and the second insulating plate is fixedly connected to the second insulating plate.

[0009] A number of conductive components are arranged closely in sequence. The two side guard plates are respectively on both sides of the number of conductive components. The screws of the clamping bolts respectively penetrate through the two side guard plates and the number of conductive components and cooperate with nuts.

[0010] As a preference of this sealing connection mechanism, the connector further includes two clamping spring pieces. The two clamping spring pieces are respectively on the outer sides of the two side guard plates. The clamping bolt penetrates through the two clamping spring pieces. The two clamping spring pieces respectively abut against the nut of the clamping bolt and the head of the screw.

[0011] As a preference of this sealing connection mechanism, the connector further includes an upper cover plate and a lower cover plate. The two ends of the upper cover plate are respectively fixedly connected to the upper end faces of the two intensive busbar housings, and the two ends of the lower cover plate are respectively fixedly connected to the lower end faces of the two intensive busbar housings.

The second conductive plate is placed in the second groove and fixedly connected to the second insulating plate.

[0015] As a preference of this sealing connection mechanism, an insulating sleeve is also sleeved on the screw of the clamping screw.

[0016] After adopting such a structure, the structure of the connector makes the connection effect of the two intensive busbars better, reduces the gap between the conductive plate and the copper bar of the intensive busbar. After the connector is installed, the internal part of the connector can be completely sealed in cooperation with the sealant layer structure, ensuring the sealing performance inside the connector.

[0017] The sealing layer structure of this sealed connection mechanism has advantages such as high temperature resistance, high pressure resistance, flame retardancy, insulation performance, sealing performance, and waterproof performance. At the same time, it has excellent weather resistance, aging resistance, and waterproofness, and plays roles such as sealing, shock absorption, and protection on the surface of the adherend.

[0023] As Figures 1 to 5 shown

[0024] This sealed connection mechanism includes a connector and two compact busbars 1.

[0025] The end of the compact busbar 1 has five copper bars 11, and the five copper bars 11 extend out of the housing of the compact busbar 1. The two compact busbars 1 are connected by a connector.

[0026] The connector includes a clamping bolt 23, an upper cover plate 25, a lower cover plate 26, side guard plates 22, two clamping spring pieces 24, and five groups of conductive components.

[0027] The five groups of conductive components correspond one-to-one to the five copper bars 11 of the compact busbar 1. Each group of conductive components includes a first insulating plate 21a, a second insulating plate 21b, a first conductive plate 21c, and a second conductive plate 21d. The first insulating plate 21a and the second insulating plate 21b are arranged at intervals;

[0028] The end face of the first insulating plate 21a on the side close to the second insulating plate 21b is provided with a first groove. The first conductive plate 21c is placed in the first groove and adhesively fixed to the first insulating plate 21a. The end face of the second insulating plate 21b on the side close to the first insulating plate 21a is provided with a second groove. The second conductive plate 21d is placed in the second groove and adhesively fixed to the second insulating plate 21b. A gap for inserting the copper bar 11 is left between the first conductive plate 21c and the second conductive plate 21d.

[0029] Five groups of conductive components are arranged closely in sequence. The two side guard plates 22 are respectively located on both sides of the five groups of conductive components after arrangement. The screw rods 23a of the clamping bolts 23 respectively penetrate through the two side guard plates 22 and the five groups of conductive components and cooperate with the nuts 23b. An insulating sleeve 23c is also sleeved on the screw rod 23a of the clamping bolt. The insulating sleeve 23c contacts the first insulating plate 21a and the second insulating plate 21b of the five groups of conductive components.

[0030] Two clamping spring pieces 24 are respectively located outside the two side guard plates 22. The clamping bolt 23 penetrates through the two clamping spring pieces 24. The two clamping spring pieces 24 respectively abut against the nut 23b of the clamping bolt 23 and the head of the screw rod 23a. There is no contact between the first conductive plate 21c and the second conductive plate 21d of the conductive component and the clamping bolt 23.

[0031] The two ends of the upper cover plate 25 are respectively fixed to the upper end faces of the two enclosures of the compact busbar 1 by bolts. The two ends of the lower cover plate 26 are respectively fixed to the lower end faces of the two enclosures of the compact busbar 1 by bolts.

[0032] A sealing layer structure is arranged at the gap between the compact busbar 1 and the connector. The sealing layer structure includes a sealant layer 31, a tin foil aluminum skin 32 and a temperature indicating wax paper 33.

[0033] The joint gaps of the four compact busbars 1 are filled with sealant. The sealant layer 31 is formed by filling the sealant in the gap between the compact busbar 1 and the connector. The sealant used for the sealant layer 31 is an insulating, sealing and waterproof sealant. The sealant layer 31 has a withstand voltage of 34 KV, a low temperature resistance of -50 °C and a high temperature resistance of 250 °C.

[0034] The sealant is an imported high temperature resistant, high voltage resistant insulating, sealing and waterproof glue used to fill and seal the gaps of the busbar. The characteristics of the sealant are convenient for later maintenance, easy to seal at the busbar joints, the glue will not drip down when applied vertically, and it will not bring potential safety hazards to construction and later use.

[0035] The tin foil aluminum sheet 32 is wound around the outside of the gap between the compact busbar 1 and the connector. The tin foil aluminum sheet 32 is located outside the sealant layer 31. The tin foil aluminum sheet 32 with the same performance as the above glue is used to externally protect and seal the construction part of the sealant, effectively ensuring that high-temperature water vapor will not penetrate into the busbar. It effectively protects the safe and reliable operation of the equipment. The tin foil aluminum sheet 32 performs secondary protection at the gap and is wound around the busbar joint.

[0036] The temperature indicating wax paper 33 is pasted on the outside of the tin foil aluminum sheet 32. The temperature indicating wax paper 33 is pasted at the joint, and the change in the color of the wax paper is used to reflect the change in the temperature of the busbar, so as to monitor the operating state of the busbar in a timely and effective manner.

[0037] The above is only one implementation mode of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several variations and improvements can be made, and these should also be regarded as belonging to the protection scope of the present invention.
