Description

Removable heating-expend for perlite stove

Technical field

The utility model relates to a kind of heating bloating plant of making the particulate state pearlstone.

Background technology

Pearlstone is a kind of well behaved lagging material and being widely used in the various industrial production, it not only has excellent heat insulation performance, and light weight, cost are low, raw material sources are extensive, the particulate state bulk cargo of making can be made various difform insulation blocks and be used for the heat preservation construction operation, also the particulate state bulk cargo of making can be directly used in the heat retaining operation.The production equipment of existing particulate state pearlstone is fixed batch production production equipment, the raw material preheating of production equipment, adds thermal expansion and is finished by preheating oven and heating expansion furnace respectively.For the construction operation that a large amount of use particulate state bulk cargos are incubated, the particulate state bulk cargo will be through packing, transportation, the scene storage of bulk cargo, operation such as remove down and process could finally be incubated equipment or device.Therefore, not only the heat preservation construction scene will be provided with special place and the device deposited, and the particulate state bulk cargo at packing, transportation, scene storage, to remove down etc. in the process particulate state bulk cargo powder phenomenon-tion serious, it is also very big that material spreads vector, thereby increased the expense of heat retaining operation greatly.Simultaneously, the particulate state bulk cargo also very easily moisture absorption make moist and influence the heat retaining operation quality.

The utility model content

The purpose of this utility model provides a kind ofly to be convenient to carry, can be at heat preservation construction field fabrication particulate state pearlstone, preheating chamber and heating expansion chamber are arranged in the body of heater, and the raw material ore in sand form is gone into the removable heating-expend for perlite stove of once making pearlstone finished product pellet behind the stove.

Removable heating-expend for perlite stove is by frame, in, outside wall surface has the inner core of guide spiral plate, suit also connects the middle tube that is fixed on the inner core, suit also connects the shaft that the inner-wall surface that is fixed on the middle tube has the urceolus formation that rolling ring is housed on the guide spiral plate outside wall surface, the raw material ore in sand form preheating feed tank of opening for feed is arranged at its bottom that tube is positioned at stove tail end one end in being loaded on, being loaded on the top that inner core is positioned at stove tail one end discharge port place has the venting port bottom that the pearlstone finished product Material collecting box for harvesting of drainage conduit is arranged, be loaded on inner core and be positioned at the heating expanded feed case of burner one end, integral body is connected the air blast charge heating case on the heating expanded feed case, flame burner on air blast charge heating case is connected and fixed, have motor, blast orifice connects gas blower that inlet mouth connects with the preheated tank air outlet by pipeline and by the motor that is fixed on the frame with the burner blast inlet, the step-down gear that input shaft connects with motor shaft, be fixed on driving wheel that the frame upper whorl axial connects with speed reducer output shaft and the shaft drive unit formation that is fixed on the shaft bogie wheel formation on the frame by the wheel carrier supporting by wheel carrier supporting, shaft is bearing on driving wheel and the bogie wheel by rolling ring, rolling ring and driving wheel, the bogie wheel friction transmission cooperates, and shaft rotates under drive wheel.In preheating feed tank and the heating expanded feed case the continuous glassware that is fixedly connected with shaft is arranged, preheating feed tank and heating expanded feed case are fixed on the frame by bracket supports.The annular chamber surrounding that annular chamber surrounding that tube inner-wall surface and inner tank theca face surround in the shaft and middle drum outer wall face and outer tube inner wall face surround constitutes the preheating chamber of heating expansion furnace, inner core tube chamber constitutes the heating expansion chamber of heating expansion furnace, and preheating chamber communicates with the heating expansion chamber by heating expanded feed case.

During the work operation, shaft is rotated by drive wheel by motor, and the flame burner sprays the high temperature fireworks in the heating expansion chamber.Ore in sand form in the preheating feed tank is added in the preheating chamber by the continuous glassware that rotates with shaft is continuous, enters ore in sand form in the preheating chamber and is heated to thermal radiation and thermal conduction that burner moves through the locular wall face under the guiding of spiral charging guide plate.The ore in sand form of preheating is fallen in the heating expanded feed case and then by the continuous glassware that rotates with shaft by preheating chamber end discharge port continuous being added to of the ore in sand form of preheating is heated in the expansion chamber.The ore in sand form that adds in the heating expansion chamber is made insulation pearlstone pellet by the heating of high temperature fireworks, the softening expansion when the stove tail moves under the guiding of spiral charging guide plate, the discharge port that is positioned at the stove tail by the heating expansion chamber falls into the finished product Material collecting box for harvesting and then is discharged out of the furnace by drainage conduit, and furnace gas is discharged out of the furnace by finished product Material collecting box for harvesting top.

In order to prevent that the high temperature fireworks that the flame burner ejects from heating the normal operation that expansion chamber advances jet-burner generation sinuous flow, guarantees stove and accessory, further improving of removable heating-expend for perlite stove is, the heating expansion chamber advances burner sections peripheral wall surfaces the whole flow deflector that connects, and flow deflector is uniform along the chamber peripheral wall surfaces.

After making shaft rolling ring wearing and tearing, can change, the further improvement of removable heating-expend for perlite stove is that the shaft urceolus is installed the web plate that rolling ring place is uniformly distributed with along the circumference and drum outer wall face integral body is connected, rolling ring has and the corresponding connecting arm that is connected with rolling ring integral body of web plate, and connecting wall connects rolling ring with web plate and is fixed on the shaft.

The removable heating-expend for perlite stove that the utility model provides is a modular construction, is convenient to transportation and heat preservation construction scene and installs and uses.The preheating of raw material ore in sand form, add thermal expansion and in stove, once finish, not only reduced the equipment consumption, and reduced the consumption of the energy.Field fabrication, eliminated the disadvantageous effect of batch production production in the past to pearlstone quality, heat preservation construction quality, reduced simultaneously pearlstone packing, transportation, link such as store in a warehouse, remove down and its production cost is reduced greatly and heat preservation construction takes up an area of and expense significantly reduces.
