Description

Technical Field

[0001] The utility model belongs to the technical field of tin smelting production, and in particular relates to a connecting device for the rapid installation of a rotating insulating porcelain column for tin smelting electric dust removal. Background Art

[0002] During the tin smelting process, the flue gas generated by the top-blown furnace is dedusted by the electrostatic precipitator. Since the insulating porcelain columns of the electrostatic precipitator electric field are in a high temperature and high voltage environment for a long time, they often break. The insulating porcelain columns must be replaced when the top-blown furnace is not blowing. However, the top-blown furnace cannot stop blowing for too long, otherwise it will affect the normal operation of the entire tin smelting system. The existing insulating porcelain columns are very inconvenient to install, which affects the replacement efficiency.

[0003] Therefore, how to provide a connection device for the rapid installation of rotating insulating porcelain columns for tin smelting electrostatic precipitators is a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0009] A pin rod is inserted into the central axis hole and the through hole and limits the connection position of the connecting pin on the mounting seat.

[0010] The beneficial effect of the utility model is that: a mounting hole for the connecting pin and the positioning pin to pass through is arranged on the mounting seat, the positioning pin is used to limit the position of the connecting pin on the mounting seat, so that the positioning pin and the connecting pin have a vertical limiting effect, and finally the positioning pin and the connecting pin are passed through the pin rod. When in specific use, the mounting seat is connected to the insulating porcelain column through the connecting pin, connected to the reducer shaft sleeve through the positioning pin, and fixed by the pin rod, so as to realize the rapid connection and assembly of the insulating porcelain column.

[0011] Preferably, the outer side wall of the mounting seat has a circumferential surface, the mounting hole passes through the outer side wall of the mounting seat, and a positioning block is fixed on the inner hole wall of the mounting hole and corresponding to the center position of the mounting seat.

[0012] The resulting technical effect is that the positioning block is used to limit the pre-assembly position of the connecting pin.

[0013] Preferably, the axial dimension of the connecting pin is larger than the circumferential diameter dimension of the mounting seat, and a positioning groove is provided on the outer side wall of the connecting pin, one end of the positioning groove extends to one end surface of the connecting pin, and the other end extends to the middle part of the connecting pin, and the positioning block is adapted to be slidably connected in the positioning groove.

[0014] The resulting technical effect is that the cooperation between the positioning groove and the positioning block limits the circumferential rotation of the connecting pin, and also performs preliminary positioning to ensure the subsequent connection between the positioning pin and the pin rod.

[0015] Preferably, a positioning plane is opened in the middle of the two outer side walls of the connecting pin, the through hole passes through the positioning plane, and one end of the positioning pin abuts against the positioning plane.

[0016] The resulting technical effect is that the positioning plane can ensure the vertical fit between the connecting pin and the positioning pin, and further ensure the coaxiality between the through hole and the central axis hole.

[0017] Preferably, a limiting step is provided at the other end of the positioning pin, and the axial dimension of the positioning pin is smaller than the axial dimension of the connecting pin.

[0018] The resulting technical effect is that the limiting step limits the installation position of the pin rod on the one hand, and is also convenient for connecting with the reducer shaft sleeve on the other hand.

[0019] Preferably, both ends of the pin rod extend out of the other end of the positioning pin respectively, and the two ends of the pin rod are bent at angles to limit the axial positions of the two groups of positioning pins.

[0020] The resulting technical effect is: the overall connection effect of the device is limited by the bending of the pin rod, and the connection is convenient and efficient. BRIEF DESCRIPTION OF THE DRAWINGS
