Abstract

The invention relates to the technical field of exhaust pipes, and discloses an exhaust pipe capable of preventing tuyere blockage and having automatic replacing and warning functions. The exhaust pipe comprises a shell, wherein a conversion groove is formed in the top of the shell, filter screens are movably connected to the two sides of the conversion groove, starting grooves are formed in the left side of the shell, and a starting block is movably connected to the top of each starting groove; and a rotating block is movably connected to the bottom of each starting groove, and an electric contact is fixedly connected to the outer side of each rotating block. According to the exhaust pipe capable of preventing tuyere blockage and having the automatic replacing and warning functions, through cooperation of the starting blocks and the rotating blocks, when the filter screens fail due to blockage, an electromagnet circuit is switched on, electromagnets and a permanent magnet interact to drive a clamping key to move, the locking state of the failed filter screens is released, meanwhile, the failed filter screens move downwards under the action of gravity of a balancing weight, and standby filter screens are driven to enter a working position through interaction with a transmission group, so that automatic replacement of the filter screens is realized, the exhaust efficiency of the exhaust pipe is prevented from being influenced by blockage of the filter screens, and dust concentration is prevented from rising.

Example Embodiment

[0026]Next, the technical solutions in the embodiments of the present invention will be apparent from the embodiment of the present invention, and it is clearly described, and it is understood that the described embodiments are merely embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, there are all other embodiments obtained without making creative labor without making creative labor premises.
[0027]SeeFigure 1-4A exhaust pipe preventing the air outlet blocked automatically replaces and warns, including the housing 1, the housing 1 is a metal material, the height of the housing 1 is equal to the height of the filter 3, enhancing the strength of the housing 1, It is conducive to extending the service life of the product, facilitating the mating of the filter 3 and the airway, so that the filter 3 is fully filtered through the gas, reducing the contamination of the atmosphere, the top of the casing 1 is opened, the conversion groove 2 side Active connection with the filter 3, the bottom of the filter 3 is opened, and the weight of the positioning groove is placed in the bottom of the weight, and the height of the positioning groove is greater than the diameter of the card key 12, and the tank 12 and the positioning groove With each other, the filter 3 is fixed in the airway of the housing 1, and the automatic replacement and trigger buzzer 20 of the filter 3 is realized by placing the weight block in the weight groove, and the housing 1 is opened on the left side. 4, the top of the starting groove 4 is connected to the start block 5, the starting slot 4 bottom activity is connected to the rotating block 6, the rotary block 6 includes a rotating disk and a contact strut, the strut surface is smooth, when the start block 5 is a housing 1 When the stroke is increasing, the strut is extruded, so that the strut phase is opened, the rotary disk is rotated, and the electrical contact 7 is in contact with the contact block 9, and the electromagnet 14 is powered, and the automatic replacement of the filter 3 is realized. .
[0028]The outer side of the rotary block 6 is fixedly connected to the electrical contact 7, and the rotary block 6 is fixedly connected to the spring 18, and the inside of the start slot 4 is fixed to the contact block 9, and the casing 1 is opened on both sides of the casing 10. The spring two 11, the outer side of the spring, two 11 is fixedly connected, the card key 12 is a metal material, and the diameter of the card key 12 is smaller than the diameter of the cartridge 10, and the strength of the tank 12 is increased, and it is easy to close the card button 12 The movement in the card groove 10 allows the card key 12 to move the locking state in the magnetic field of the electromagnet, unlock the locking state of the filter 3, and the inside of the card key 12 is fixedly connected to the permanent magnet 13, the permanent magnet 13 and electromagnetic Contrary to the opposite direction of the iron 14, when the electromagnet 14 is powered, the electromagnet 14 generates a magnetic field, and the permanent magnet 13 is attracted to each other due to opposite magnetic properties, and the tab button 12 overcomes the spring two 11 elastic inward. The locking state of the release filter 3 is released, and the automatic replacement of the filter 3 is realized. The electromagnet 14 is fixed to both sides of the casing 1, and two symmetrical control grooves 15 are opened at the bottom of the casing 1, and the control groove 15 is fixedly connected. There is a spring three 16.
[0029]The top of the spring three 16 is fixedly connected to the control block 17, and the control block 17 includes a moving block and an electrical tuning ring, and the diameter of the control block 17 is smaller than the diameter of the control groove 15, and when the filter 3 reaches the conversion slot 2 under the action of the weight block 2 At the bottom, the filter 3 drives the control block 17 to overcome the elastic movement of the spring three 16, so that the electrical tuning ring is in contact with the contact ring 18, and the buzzer 20 is powered, so that the buzzer 20 works sound, realize The function of the warning, the inner wall of the control groove 15 is fixedly connected to the contact ring 18, and the interior of the conversion groove 2 is fixedly connected to the transmission group 19, and the transmission group 19 includes a roller and a non-slip pad layer, and the non-slip pad layer is a rubber material and the surface is provided with a pattern. The group 19 is mounted to each other on both sides, under the gravity of the weight block, replace the failure filter 3 and push into the new filter 3, realize the automatic replacement of the filter 3, the housing 1 The left side is fixedly connected to the buzzer 20, and the buzzer 20 includes a circuit control assembly and a sounding assembly, and the buzzer 20 is powered by the circuit control assembly in contact with the contact ring 18 by the control block 17, thereby enabling the buzzer 20. The sound assembly works generates an audio and implements a warning function.
[0030]Working principle: When the filter 3 is operating normally, the wind pressure in the airway of the housing 1 is in the normal range, and the start block 5 cannot overcome the elastic movement of the spring 18, and the electrical contact 7 is separated from the contact block 9. The iron 14 does not electrically, the card key 12 enters the fixed groove at the bottom of the filter 3 under the action of the spring di 11 elastic force, and the locking filter 3, the control block 17 is separated from the contact ring 18, the buzzer 20 does not work, when the filter 3 When it is blocked, the wind pressure in the airway of the housing 1 is higher than the normal range, and the start block 5 overcomes the elasticity of the spring 8 under the action of the spring, rotating the block 6 rotates, so that the electrical contact 7 is in contact The block 9 is in contact, the electromagnet 14 is turned on, and the electromagnet 14 is electrically generated to generate a magnetic field and attracts each other with the permanent magnet 13, and the tab button 12 overcomes the spring two 11 elastic inward, and the locking state of the failure filter 3 is failed. The filter 3 is moved down due to placement of the weight, and the spare screen 3 is moved upward to the working position, and the automatic replacement of the filter 3 does not affect the normal operation of the exhaust pipe, and at the same time Under the action of gravity, the failed filter 3 extruded the corresponding control block 17 such that the control block 17 is in contact with the contact ring 18, thereby turning on the buzzer 20 internal circuit, the buzzer 20 emits a sound, and the warning function is achieved. When the inspection person replaces the failure filter 3, the weight of the filter 3 in the failure is moved to the alternate filter 3, thereby realizing the repetition of the product.
