Description

Technical Field

[0001] The utility model belongs to the technical field of antimony smelting, and in particular relates to an anti-emission device for an antimony oxygen lower hopper. Background Art

[0002] Antimony oxide is the raw material for smelting refined antimony and needs to be added into the furnace for reduction smelting, refining and other processes to obtain qualified refined antimony.

[0003] Antimony oxide is generally stored in a storage hopper above the kiln. A feeding nozzle is set at the bottom of the storage hopper, and antimony oxide enters the kiln through the feeding nozzle. The temperature above the kiln is high. In order to prevent the feeding nozzle from deforming at high temperature, the feeding nozzle is generally 200mm to 500mm away from the kiln feed port. Due to the strong fluidity of antimony oxide and the high temperature of the kiln feed port, antimony oxide volatilizes and escapes from the feeding nozzle, causing the loss of valuable metals. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide an antimony oxide discharge hopper anti-emission device to prevent antimony oxide from escaping from the discharge nozzle when discharging.

[0005] The utility model solves the above problems through the following technical means:

[0006] An antimony oxide hopper anti-escape device comprises an antimony oxide storage hopper and a discharge nozzle arranged at the bottom of the antimony oxide storage hopper; it also comprises a guide tube slidably sleeved with the discharge nozzle up and down and an operating mechanism for driving the guide tube to rise and fall.

[0007] Furthermore, the operating mechanism includes a fixed rod, an operating rod and a movable rod. The fixed rod is fixedly connected to the antimony oxygen storage bucket. A pin is fixedly provided on the fixed rod. The pin passes through the operating rod to realize the hinged assembly of the operating rod and the fixed rod. One end of the movable rod is hinged to the execution end of the operating rod, and the other end is hinged to the side wall of the guide tube.

[0008] Furthermore, one end of the pin shaft away from the fixing rod is threadedly connected with a locking nut.

[0009] Furthermore, the pin shaft is integrally connected to the fixing rod.

[0010] Furthermore, a flow guide nozzle is threadedly connected to the bottom of the flow guide tube.

[0011] Furthermore, the guide nozzle is trumpet-shaped.

[0012] Beneficial effects of the utility model:

[0013] The antimony oxide hopper anti-emission device of the present application comprises an antimony oxide storage hopper and a discharge nozzle arranged at the bottom of the antimony oxide storage hopper; and also comprises a guide tube slidably sleeved with the discharge nozzle up and down and an operating mechanism for driving the guide tube to rise and fall. The antimony oxide hopper anti-emission device of the present application can prevent antimony oxide from escaping from the discharge nozzle when discharging. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0015] Figure 1 It is a structural schematic diagram of a preferred embodiment of the utility model. DETAILED DESCRIPTION

[0016] The utility model will be described in detail below with reference to the accompanying drawings. Figure 1 As shown: an antimony oxide hopper anti-escape device includes an antimony oxide storage hopper 1 and a discharge nozzle 2 arranged at the bottom of the antimony oxide storage hopper; it also includes a guide tube 3 slidably sleeved with the discharge nozzle up and down and an operating mechanism for driving the guide tube to rise and fall, wherein the guide tube is located above the feed port of a furnace 5; the operating mechanism includes a fixed rod 10, an operating rod 7 and a movable rod 6, the fixed rod is fixedly connected to the antimony oxide storage hopper, a pin shaft 8 is integrally fixedly provided on the fixed rod, the pin shaft passes through the operating rod to realize the hinged assembly of the operating rod and the fixed rod, one end of the movable rod is hinged to the execution end of the operating rod, and the other end is hinged to the side wall of the guide tube.

[0017] When the operating end of the operating rod is pressed down, the active rod is linked to drive the guide tube to rise; when the operating end of the operating rod is lifted up, the active rod is linked to drive the guide tube to fall. When antimony oxide is fed, the guide tube is controlled to fall so that the bottom of the guide tube is connected to the feed port of the furnace to prevent antimony oxide from escaping; after the feeding is completed, the guide tube is controlled to rise to prevent the guide tube from being deformed by continuous high temperature. In this way, the purpose of preventing antimony oxide from escaping from the feed nozzle when feeding is achieved, and the loss of valuable metals is avoided.

[0018] As a further improvement of the above technical solution, the end of the pin shaft away from the fixed rod is threadedly connected with a locking nut 9. During operation, the locking nut is tightened to press the operating rod, and the extrusion force is used to achieve hinge locking between the operating rod and the fixed rod, so that the guide tube stops at a suitable height position.

[0019] As a further improvement to the above technical solution, the bottom of the guide tube is threadedly connected with a guide nozzle 4, which is trumpet-shaped. During operation, the guide nozzle contacts the kiln, and when it is severely deformed, the guide nozzle can be removed and replaced without removing the guide tube.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
