Description

Technical Field

[0001] This utility model relates to the field of energy and environmental technology, and in particular to a device for reusing waste heat from exhaust gas in an enameled wire production line. Background Technology

[0002] Enameled wire is a type of metal conductor coated with insulating varnish, mainly composed of a conductor and an insulating varnish layer. During the production of enameled wire, several stages generate waste gas. In this process, the solvent in the insulating varnish evaporates, forming waste gas. Utilizing the waste heat from this waste gas to preheat the varnish can reduce energy consumption and improve the fluidity of the varnish. When collecting waste gas, it is usually filtered into the fan through a filter screen on one side. Over time, dust accumulates inside the filter screen. When dust accumulates for a long time, the mesh becomes clogged. When the filter screen is severely clogged, the fan's energy consumption may increase, which not only increases production and maintenance costs but may also shorten the fan's lifespan. When the waste heat is insufficient, the temperature of the heated medium may not reach the expected requirements, thus reducing the overall efficiency of the waste heat recovery system.

[0027] Example 1

[0028] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a waste heat recovery device for waste gas from an enameled wire production line. The waste heat recovery device for waste gas from an enameled wire production line includes a main component 100, a cleaning component 200, and a transmission component 300. The three components work together to clean the dust on the fan filter screen.

[0029] Specifically, the cleaning component 200 includes a cleaning element 201, which includes a sliding frame 201a, a fixed shaft 201b, and sliding bars 201c. The fixed shaft 201b slides on the inner wall of the sliding frame 201a. A sliding groove 201b-1 is provided on the fixed shaft 201b. There are two sliding bars 201c, both of which slide on the inner wall of the sliding groove 201b-1. The other end of the sliding bar 201c is fixed to one end of the sliding frame 201a.

[0030] When cleaning is required, the sliding frame 201a is moved, which causes the sliding strip 201c to move on the inner wall of the sliding groove 201b-1. The movement of the sliding strip 201c can squeeze the sliding groove 201b-1, causing the sliding groove 201b-1 to rotate. The rotation of the sliding groove 201b-1 drives the fixed shaft 201b to rotate, and the rotation of the fixed shaft 201b can clean the filter screen 105.

[0031] Specifically, the transmission assembly 300 is disposed on one side of the sliding frame 201a and includes a transmission component 301, including a rotating bar 301a, a sliding shaft 301b, and a moving frame 301c.

[0032] By moving the rotating bar 301a, the sliding shaft 301b will slide on the inner wall of the moving frame 301c. The movement of the moving frame 301c can squeeze the sliding frame 201a, causing the sliding frame 201a to move.

[0033] Example 2

[0034] Reference Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0035] Specifically, the sliding frame 201a is covered by a support frame 202a, and a pull rod 202b is provided at one end of the sliding frame 201a. The pull rod 202b is inserted into the inner wall of the support frame 202a and slides.

[0036] The support frame 202a is fixed to the inner wall of the fan 103, and the other end of the pull rod 202b is fixed to one end of the movable frame 301c.

[0037] The support frame 202a is used to support the pull rod 202b. By moving the pull rod 202b, the movement of the pull rod 202b drives the sliding frame 201a to move. The movement of the sliding frame 201a can make the fixed shaft 201b rotate.

[0038] Specifically, a rotating rod 202c is provided at one end of the fixed shaft 201b, a connecting bar 202d is provided at one end of the rotating rod 202c, and a brush head 202e is provided at one end of the connecting bar 202d.

[0039] The movement of the sliding bar 201c can compress the sliding groove 201b-1, causing the sliding groove 201b-1 to rotate. The rotation of the sliding groove 201b-1 drives the fixed shaft 201b to rotate, which in turn drives the connecting bar 202d to rotate. The rotation of the connecting bar 202d drives the brush head 202e to rotate, which in turn cleans the dust on the filter screen 105.

[0040] Specifically, a connecting rod 302a is inserted into the inner wall of the rotating bar 301a, and a turntable 302b is sleeved on the outer side of the connecting rod 302a. One end of the sliding shaft 301b is fixed to one end of the turntable 302b.

[0041] The rotation of the connecting rod 302a drives the turntable 302b to rotate, the rotation of the turntable 302b drives the rotating bar 301a to rotate, the rotation of the rotating bar 301a drives the sliding shaft 301b to slide on the inner wall of the moving frame 301c, the moving frame 301c moves through the guide of the moving frame 301c, and the movement of the moving frame 301c drives the pulling rod 202b to move.

[0042] Specifically, a fixing frame 302c is also fitted on the outside of the connecting rod 302a, and a fixing rod 302d is provided on one side of the fixing frame 302c.

[0043] Fixing rod 302d. Fixed to the inner wall of fan 103.

[0044] The fixed rod 302d is used to support the turntable 302b, and the fixed frame 302c is used to support the movable frame 301c.

[0045] Specifically, an impeller 302e is provided at one end of the connecting rod 302a, and a duct 302f is provided on one side of the impeller 302e.

[0046] The duct 302f is used to guide the gas and accurately transmit it to the impeller 302e.

[0047] When collecting gas, gas is injected through the filter 105 and also through the duct 302f. The gas is blown by the wind force towards the impeller 302e, causing the impeller 302e to rotate. The rotation of the impeller 302e causes the connecting rod 302a to rotate, and the rotation of the connecting rod 302a drives the turntable 302b to rotate.

[0048] Example 3

[0049] Reference Figures 4-5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0050] Specifically, one end of the duct 302f is equipped with a gas collection hood 302g, and the other end of the duct 302f is fixed to one end of the support frame 202a.

[0051] The airflow is drawn into the inner wall of the gas collection hood 302g, and then into the inner wall of the air duct 302f, which transmits the airflow to the impeller 302e, causing the impeller 302e to rotate.

[0052] Specifically, a movable strip 302h is inserted into the inner wall of the fixed frame 302c, and the other end of the movable strip 302h is fixed to one end of the movable frame 301c.

[0053] The movable bar 302h is used to support the movable frame 301c, and the fixed frame 302c is used to support the movable bar 302h. When the movable frame 301c moves, it will cause the movable bar 302h to move within the inner wall of the fixed frame 302c.

[0054] Specifically, a protective shell 302i is provided at one end of the connecting rod 302a, and a protective disc 302j is provided at one end of the moving bar 302h.

[0055] The protective shell 302i is used to support the rotating bar 301a to prevent the rotating bar 301a from shifting during rotation, and the protective disc 302j is used to support the moving bar 302h.

[0056] Specifically, it also includes the main component 100, including a gas collection box 101, a ventilation duct 102, a fan 103, an exhaust bucket 104, and a filter screen 105. The ventilation duct 102 is located at the top of the gas collection box 101, the gas collection box 101 is located at the bottom of the ventilation duct 102, the fan 103 is located at the bottom of the ventilation duct 102, the exhaust bucket 104 is located at the top of the gas collection box 101, the filter screen 105 is located on the inner wall of the fan 103, and the support frame 202a is located on the inner wall of the fan 103.

[0057] The gas collection box 101 can be used as a device for collecting waste gas. After the gas collection box processes the collected gas, the ventilation duct 102 is used to discharge the processed gas into the atmosphere or transport it to the next processing stage. The fan 103 can generate negative pressure to draw the gas into the gas collection box. The discharge bucket 104 can serve as a buffer area to make the gas more stable before discharge. The filter screen 105 is used to filter impurities in the gas during transmission.

[0058] In operation, the fan 103 draws gas into the gas collection box. Some gas flows into the inner wall of the gas collection hood 302g and then into the inner wall of the duct 302f. Guided by the duct 302f, the gas is precisely transmitted to the impeller 302e. The airflow causes the impeller 302e to rotate, which in turn rotates the connecting rod 302a. The rotation of the connecting rod 302a then rotates the turntable 302b, which in turn rotates the rotating bar 301a. The rotation of the rotating bar 301a causes the sliding shaft 301b to slide against the inner wall of the moving frame 301c. The movement of the moving frame 301c moves the pulling rod 202b, and the moving frame 301c moves as well. It also causes the moving strip 302h to move within the inner wall of the fixed frame 302c. The movement of the pulling rod 202b causes the sliding frame 201a to move, and the movement of the sliding frame 201a causes the sliding strip 201c to move. The movement of the sliding strip 201c can squeeze the sliding groove 201b-1, causing the sliding groove 201b-1 to rotate. The rotation of the sliding groove 201b-1 causes the fixed shaft 201b to rotate, and the rotation of the fixed shaft 201b causes the connecting strip 202d to rotate. The rotation of the connecting strip 202d can then cause the brush head 202e to rotate, and the rotation of the brush head 202e can clean the dust on the filter screen 105.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
