DETAILED DESCRIPTION

[0031] The following will be described in detail with reference to the accompanying drawings. Figures 1-4 The present application is further described in detail.

[0032] The present application discloses a tar discharging device capable of preventing smoke from being generated. Referring to Figure 1 and Figure 2 , a plurality of box bodies 1 are provided, and a box opening 11 is formed in a side wall of each box body 1. A box door 12 is installed on each box body 1, and the box door 12 is used to close the box opening 11. A tar pipe 2 is arranged through each box body 1, a tar valve 21 is installed on the tar pipe 2, and the tar pipe 2 is connected to a tar discharging port of a condenser 22 at an end thereof located outside the box body 1. A sliding seat 31 is installed in each box body 1, a tar bucket 3 is placed on the sliding seat 31, and the tar bucket 3 is used to receive tar dripping from the tar pipe 2. A set of sliding rails 32 is installed in each box body 1, and the sliding seat 31 is slidingly arranged on the sliding rails 32. The box opening 11 is used for moving the tar bucket 3, so as to facilitate the tar bucket 3 to move into and out of the box body 1. An air supplement pipe 4 is arranged in communication with each box body 1, an air supplement one-way valve 41 is installed on the air supplement pipe 4, and an air source of non-polluted gas is connected to an end of the air supplement pipe 4 away from the box body 1. An air extraction pipe 5 is arranged in communication with each box body 1, and an air extraction one-way valve 51 is installed on the air extraction pipe 5. A flue gas pipe 6 is arranged in common communication with ends of the air extraction pipes 5 away from the box bodies 1, an air extraction fan 61 is installed in the flue gas pipe 6, and a flue gas treatment equipment 62 is connected to an end of the flue gas pipe 6 away from the air extraction pipe 5. When tar in the condenser 22 is discharged, the tar bucket 3 is first placed in each box body 1, then the box door 12 is used to close the box opening 11 and the air supplement one-way valve 41 is closed, after which the tar valve 21 and the air extraction one-way valve 51 are opened. At this time, the tar in the condenser 22 drips into the tar bucket 3 through the tar pipe 2, flue gas in each box body 1 is discharged to the flue gas treatment equipment 62 through the air extraction pipe 5, and a micro-negative pressure state is formed in each box body 1, which reduces the situation of flue gas escaping and the situation of tar splashing. When the tar discharging is completed, the tar valve 21 is closed and the air supplement one-way valve 41 is opened, the air extraction one-way valve 51 is closed after a period of time, and finally the box door 12 is opened to take the tar bucket 3 out of each box body 1. During the process of discharging the tar in the condenser 22, flue gas in each box body 1 is discharged to the flue gas treatment equipment 62, which reduces the situation of flue gas escaping during the tar discharging.

[0033] In order to reduce the gas escaping from the box door 12 and the box opening 11, referring to Figures 1 to 4 A sealing frame 8 is installed on the box door 12, and a rubber layer 81 is wrapped on the outer wall of the sealing frame 8. The rubber layer 81 is used to abut against the sealing rubber strip 7, so as to reduce the damage of the sealing rubber strip 7 by the edge of the sealing frame 8. The inner wall of the box opening 11 is wrapped with the sealing rubber strip 7, and a sealing cavity 71 is formed in the sealing rubber strip 7. The sealing frame 8 on the box door 12 is inserted into the box opening 11, the sealing frame 8 presses the sealing rubber strip 7, and the sealing cavity 71 facilitates the deformation of the sealing rubber strip 7, so that the sealing rubber strip 7 is tightly attached to the rubber layer 81.

[0034] In order to movably install the box door 12 on the box body 1, referring to Figures 1 to 4 A plurality of installation grooves 911 are formed on the box body 1, a piston cylinder 91 is installed in each installation groove 911, and a door frame 9 is movably installed on the output shaft of the piston cylinder 91. A group of dovetail sliding grooves 921 are formed on the door frame 9, and the dovetail sliding grooves 921 are parallel to each other. A dovetail sliding block 92 is slidably installed in each dovetail sliding groove 921, and the dovetail sliding block 92 is welded to the box door 12. When the box opening 11 is exposed, the output shaft of the piston cylinder 91 is elongated to drive the door frame 9 and the box door 12 to move away from the box body 1, so that the sealing frame 8 is moved out of the box opening 11. After the sealing frame 8 is moved out of the box opening 11, the box door 12 is moved along the door frame 9 to expose the box opening 11. When the box opening 11 is closed, the box door 12 is moved along the door frame 9 to be opposite to the box opening 11, and then the output shaft of the piston cylinder 91 is shortened to drive the door frame 9 and the box door 12 to move close to the box body 1, so that the sealing frame 8 is inserted into the box opening 11.

[0035] The implementation principle of the tar discharging device of the present application is as follows: when the tar in the condenser 22 is discharged, the tar bucket 3 is first placed in the box body 1, then the box door 12 is used to close the box opening 11 and close the air supplementing one-way valve 41, and then the tar valve 21 and the air extraction one-way valve 51 are opened. At this time, the tar in the condenser 22 is dropped into the tar bucket 3 through the tar pipe 2, and the flue gas in the box body 1 is discharged into the flue gas treatment equipment 62 through the air extraction pipe 5, so that a micro-negative pressure state is formed in the box body 1, which reduces the flue gas escaping and the tar splashing. After the tar discharging is completed, the tar valve 21 is closed and the air supplementing one-way valve 41 is opened, and after a period of time, the air extraction one-way valve 51 is closed, and finally the box door 12 is opened to take out the tar bucket 3 from the box body 1. During the tar discharging process of the condenser 22, the flue gas in the box body 1 is discharged into the flue gas treatment equipment 62, which reduces the flue gas escaping during the tar discharging process.

[0036] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application. Any equivalent changes made according to the structure, shape and principle of the present application should be covered by the protection scope of the present application.
