Detailed Description

The following description of the embodiments of the present invention is provided to facilitate the understanding of the present invention by those skilled in the art, but it should be understood that the present invention is not limited to the scope of the embodiments, and various changes will be apparent to those skilled in the art as long as they are within the spirit and scope of the present invention as defined and defined by the appended claims, and all inventions contemplated by the present invention are protected.

As shown in fig. 1 and 2, the air exhaust system of the bale press comprises an air exhaust pipeline 1 and a fan 2 installed at the outlet of the air exhaust pipeline 1, an acoustical panel 3 is arranged at the inlet of the air exhaust pipeline 1, the acoustical panels 3 are uniformly distributed along the circumference and at the inlet of the air exhaust pipeline 1, the acoustical panel 3 is a hollow arc plate, and an inner cavity of the acoustical panel is filled with sound absorbing cotton.

The silencing plate 3 surrounds through the bottom plate, the inner arc plate and the outer arc plate to form an arc plate with a cavity, after the silencing cotton is filled, one end opposite to the bottom plate is inserted into the end plate 31 to be fixed, one side, facing the end plate 31, of the inner arc plate and the outer arc plate is provided with a convex part with a conical end part, the end plate is provided with a groove corresponding to the convex part, and the convex part is extruded into the groove to be fixed.

A silencing cavity is formed between two adjacent silencing plates 3, and a through hole corresponding to the silencing cavity is formed in the end plate 31 and used for allowing smoke dust and waste gas to pass through. The end plate 31 is welded to the inner wall of the exhaust duct 1.

Exhaust duct 1's middle part is provided with smoke and dust filter screen 4, and on smoke and dust filter screen 4 was fixed in filter screen frame, filter screen frame was last to be provided with the boss, and this boss corresponds with the draw-in groove that sets up on exhaust duct 1, installs on filter screen frame that smoke and dust filter screen 4 inserted from exhaust duct 1's top surface, when needing to be changed smoke and dust filter screen 4, only need follow the top surface take out change can, avoided dismantling exhaust duct 1. A dust collecting box 41 is arranged below one side of the smoke dust filter screen 4 facing the air inlet, and the dust collecting box 41 is a rectangular box body and is welded on the exhaust pipeline 1 and used for collecting the smoke dust filtered by the smoke dust filter screen 4.

The waste gas processor 5 is arranged between the fan 2 and the smoke dust filter screen 4, and waste gas which is filtered to smoke dust by the smoke dust filter screen 4 enters the waste gas processor 5 to carry out chemical reaction, so that toxic gas in the waste gas is converted into substances harmless to the environment.

The exhaust gas processor 5 includes a housing 51, an inlet pipe 52 and an outlet pipe 53 are oppositely disposed at both sides of the upper portion of the housing 51, and the inlet pipe 52 and the outlet pipe 53 are detachably connected to corresponding ends of the exhaust duct 1 by flanges 58. A partition plate 55 is fixedly connected to the top plate of the box body 51, and the bottom surface of the partition plate 55 is higher than the bottom surface of the box body 51. The upper part of the box body 51 is divided by the partition 55, and under the suction action of the fan 2, the waste gas entering from the inlet pipe 52 must pass through a channel formed between the bottom surface of the partition 55 and the bottom surface of the box body 51, and as long as the liquid level of the reaction liquid 54 contained in the box body 51 is higher than the bottom surface of the partition 55, the waste gas must enter the reaction liquid 54 and react with the reaction liquid 54.

A return pipe 56 is arranged above the box body 51, two ends of the return pipe 56 are introduced into the box body 1 and positioned at two sides of the partition plate 55, a first valve 57 is arranged on the return pipe 56, a second valve 59 is arranged on the exhaust duct 1 between the exhaust gas processor 5 and the fan 2, and both the first valve 57 and the second valve 59 are electromagnetic valves.

The exhaust gas that has not sufficiently reacted with the reaction liquid 54 in the first pass may also be returned to the end of the intake pipe 52 through the return pipe 56 to be reacted with the reaction liquid 54 again. When the first valve 57 on the return pipe 56 is opened, the second valve 59 must be closed first, otherwise it is easy to make the waste gas directly enter the end of the fan 2 through the return pipe 56 without passing through the reaction liquid 54. The second valve 59 can avoid frequent start of the fan 2, which causes waste of electric energy and loss of the fan. The first valve 57 and the second valve 59 are both solenoid valves, and a switch button for controlling the on-off of the solenoid valves is arranged near the bale press, so that the control of workers is facilitated.

When the bale press is working, the staff opens the starting switch of fan 2, and for convenient operation, the start-stop switch of fan 2 sets up and does the characters mark side by side with the start-stop switch of first valve 57 and second valve 59. In order to visually observe the effect of the waste gas treatment, a digital display type gas detector can be additionally arranged between the fan 2 and the waste gas processor 5 to detect the content of the corresponding gas, if the content is too high, the second valve 59 can be closed, the first valve 57 is opened, the gas is enabled to react with the reaction liquid 54 again through the return pipe 56 until the data detected by the gas detector reaches the environmental protection standard, the first valve 57 is closed, and the second valve 59 is opened.
