Abstract
The utility model discloses a sunken external pressure manhole cover for a bulk cement tanker. The manhole cover comprises an outer barrel welded in a tank body, an inner barrel, and a round connecting plate fixed between the outer barrel and the inner barrel, wherein the connecting plate is hinged with a plurality of pressure plates; the inner barrel is buckled with a cover plate; one side of the cover plate is hinged to the connecting plate, and the other side of the cover plate is provided with a U-shaped frame; the U-shaped frame is buckled by a safety buckle arranged at the corresponding position of the connecting plate; a support pillar is arranged in the center of the cover plate in a rotary screwing mode; a plurality of pressure blocks matched with the pressure plates are fixedly arranged on the support pillar; and a handle is fixedly arranged at the upper end of the support pillar. The connecting plate is connected between the inner barrel and the outer barrel, and the outer barrel is welded in the tank body, so that welding height is reduced; and the pressure plates hinged to the connecting plate are pressed by the pressure blocks sleeved on the support pillar, so that the high sealing performance of the cover plate is effectively ensured.
Description
Technical field:
The utility model relates to bulk cement tanker and makes the field, relates in particular to a kind of bulk cement tanker sunk type external pressure manhole cover.
Background technology:
Bulk cement tanker is claimed bulk powder goods tanker again, partly is made up of special-purpose automobile chassis, Bulk cement Delivery Tankers, air pipe system, automatic unloading device etc.Be applicable to that particle diameters such as fly ash, cement, pulverized limestone, mineral powder, granulated alkali are not more than the transportation in bulk of 0.1mm powder dried material.Use in main cement mill, cement warehouse and the heavy construction building site of supplying, and can practice thrift a large amount of packing and loading and unloading work.
Bulk cement Delivery Tankers is mainly become by tank body, tank body upper end manhole cover (giving inlet point), fluidized-bed, discharge nozzle assembly, air inlet pipe and other enclosure group.
Through power takeoff and transmission shaft the power of car chassis is reached Air compressor.Air compressor fully mixes jar interior air and powder grain material to filling air in the jar, forms flow-like.When pressure arrives certain amount, open the discharging butterfly valve.To expect to discharge
Owing to bulk cement tanker is to lean on jar interior air pressure discharging, therefore the leak tightness for the external pressure manhole cover there is higher requirement, need switch conveniently, flexibly.But because the external pressure manhole cover structure design of original bulk cement carrier is unreasonable, the leak tightness of external pressure manhole cover is relatively poor after the long-term use; The height of bulk cement tanker limits, because original external pressure manhole cover self setting height(from bottom) is higher, thereby the capacity of tank body just receives certain restriction.
The utility model content:
In order to remedy the deficiency of prior art, the purpose of the utility model provides a kind of bulk cement tanker sunk type external pressure manhole cover, has reduced the height that is welded of manhole cover effectively, and the tightness of capping improves.
The technical scheme of the utility model is following:
Bulk cement tanker sunk type external pressure manhole cover; It is characterized in that: comprise outer cylinder body, the inner barrel that is welded in the tank body, the connecting panel that is fixed in the circle between outer cylinder body and the inner barrel, be hinged with several pressing plates on the connecting panel, fastening on the described inner barrel has cover plate; Cover plate one side is hinged to be installed on the connecting panel; Opposite side is provided with the U-shaped frame, and the safety catch that U type frame is installed by opposite position on the connecting panel fastens, and screwing installation is rotated at described cover plate center has pillar; Be fixed with the briquetting that matches with several pressing plates on the pillar, the pillar upper end is fixed with handle.
Described bulk cement tanker sunk type external pressure manhole cover is characterized in that: be positioned at several pressing plate one sides on the described cover plate and be provided with registration mast.
The utility model has the advantages that:
The utility model adopts between the inside and outside cylindrical shell and is connected with connecting panel, and outer cylinder body is welded in tank body, has reduced the height that is welded, and several pressing plates that are articulated on the connecting panel compress through being set in the pillar upper holder block, and actv. has guaranteed the cover plate good sealing property.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
Bulk cement tanker sunk type external pressure manhole cover; Comprise outer cylinder body 1, the inner barrel 2 that is welded in the tank body, the connecting panel 3 that is fixed in the circle between outer cylinder body 1 and the inner barrel 2, be hinged with several pressing plates 4 on the connecting panel 3, fastening on the inner barrel 2 has cover plate 5; Cover plate 5 one sides are hinged to be installed on the connecting panel 3; Opposite side is provided with U-shaped frame 6, and the safety catch 7 that U type frame 6 is installed by opposite position on the connecting panel fastens, and screwing installation is rotated at cover plate 5 centers has pillar 8; Be fixed with the briquetting 9 that matches with several pressing plates 4 on the pillar 8, pillar 8 upper ends are fixed with handle 10.
Be positioned at several pressing plate 4 one sides on the cover plate 5 and be provided with registration mast 11, highly reasonable in design, when screwing, column 8 enters into certain depth, just in time block briquetting 4 several pressing plates 4 of locking.
