Abstract

The invention discloses a box-type centrifugal fan with a detachable base. The box-type centrifugal fan with the detachable base comprises a box body and impellors, wherein the impellors are arranged in a volute; the volute is fixed in the box body; a reinforcing block is fixed on the upper plane of a base plate of the box body; a first waist-shaped through hole is formed in the reinforcing block; a second waist-shaped through hole is formed in the base plate; the first waist-shaped through hole and the second waist-shaped through hole correspond up and down; connecting groove steel is formed on the rear surface of the base plate; a buffer gasket is clamped between the connecting groove steel and the base plate; a fixing bolt sequentially passes through a connecting through hole of an upper bending part of the connecting groove steel, a central through hole of the buffer gasket, the second waist-shaped through hole and the first waist-shaped through hole from bottom to top, and the top of the fixing bolt is screwed with a fixing nut; the fixing nut presses against the upper plane of the reinforcing block. The connecting groove steel can be detached without cutting; the buffer gasket can reduce the vibration between the centrifugal fan and connecting equipments in running, and the connecting and fixing effects are improved.

Description

A kind of box centrifugal blower of detachable base
Technical field:
The present invention relates to the ventilation equipment technical field, relate in particular a kind of box centrifugal blower of detachable base.
Background technique:
Existing box centrifugal blower generally all is welded and fixed and connects channel-section steel as base on the bottom surface of casing, so that lifting, by connecting channel-section steel, be arranged on equipment or facility when mounted simultaneously, yet be fixing can't the movement owing to connecting channel-section steel, fixed hole on the connection channel-section steel and the attachment hole on equipment or facility can't coincide, while departing from, bolt just can't be fixed on centrifugal blower on equipment or facility through these two holes, need to again punch, bother very much, and some place is not while needing this to connect channel-section steel, needing to have cutting machine or other machines equipment will connect channel-section steel removes, bother so very much.
Simultaneously, it is to be rigidly connected that centrifugal blower is arranged on equipment or facility, and it is in operation and can produces mobile shake, and the of long duration connecting bolt that easily makes inner connected element or centrifugal blower be connected with equipment is loosening, need to carry out constantly repair and maintenance, very trouble.
Summary of the invention:
Purpose of the present invention is exactly the deficiency for prior art, and provide a kind of box centrifugal blower of detachable base, it can be dismantled connecting channel-section steel, without cutting, simultaneously, it can be finely tuned connecting channel-section steel, guarantee that the attachment hole connected on channel-section steel is corresponding with the fixed hole on required connection device or facility, facilitate bolt to fix, and cushion pad reduces the vibrations that centrifugal blower produces with connection device when operation, raising is connected and fixed effect.
Technology solution of the present invention is as follows:
A kind of box centrifugal blower of detachable base, comprise casing and impeller, impeller is arranged in spiral case, spiral case is fixed in casing, be fixed with reinforced block on the upper plane of the base plate of described casing, form the first waist typed through hole on reinforced block, form the second waist typed through hole on base plate, the first waist typed through hole is corresponding up and down with the second waist typed through hole, connect channel-section steel on the back side of base plate, connect clamping between channel-section steel and base plate cushion pad is arranged, fixing bolt by lower from upper successively through the connecting through hole of the upper bending part that connects channel-section steel, the central through bore of cushion pad, the second waist typed through hole and the first waist typed through hole, its top is bolted with set screw nut, set screw nut is pressed against on the upper plane of reinforced block.
Be fixed with regulating block on the upper plane of described base plate, be bolted with hand tighten screw on regulating block, the top of hand tighten screw faces toward set screw nut through regulating block, the tail end of hand tighten screw is that hand is twisted section, and the length direction that moves axially direction and the first waist typed through hole, the second waist typed through hole of hand tighten screw is same direction.
All be fixed with two reinforced blockes on the front and rear of described base plate on plane, the other all corresponding regulating blocks that is fixed with of each reinforced block.
Beneficial effect of the present invention is:
1, it makes to connect channel-section steel by fixing bolt and is fixed on casing, and the convenient channel-section steel that connects is dismantled, without cutting.
2, it,, by turning hand-held screw, makes screw promote fixing bolt and moves, thereby make to connect channel-section steel, is moved left and right fine setting, guarantees that the attachment hole connected on channel-section steel is corresponding with the fixed hole on required connection device or facility, facilitates bolt to fix.
3, its cushion pad reduces the vibrations that centrifugal blower produces with connection device when operation, improves and is connected and fixed effect, minimizing Inspection and maintenance number of times.
The accompanying drawing explanation:
Fig. 1 is perspective view of the present invention;
Fig. 2 is front view of the present invention;
The partial structurtes schematic diagram that Fig. 3 is fixing bolt of the present invention and its associated components;
Fig. 4 be fixing bolt of the present invention and its associated components change angle partial structurtes schematic diagram;
Embodiment:
Embodiment: see shown in Fig. 1 to 4, a kind of box centrifugal blower of detachable base, comprise casing 1 and impeller 2, impeller 2 is arranged in spiral case 3, spiral case 3 is fixed in casing 1, be fixed with reinforced block 4 on the upper plane of the base plate 11 of described casing 1, form the first waist typed through hole 41 on reinforced block 4, form the second waist typed through hole 111 on base plate 11, the first waist typed through hole 41 is corresponding Shang Xia 111 with the second waist typed through hole, connect channel-section steel 5 on the back side of base plate 11, connect clamping between channel-section steel 5 and base plate 11 cushion pad 6 is arranged, fixing bolt 7 by lower from upper successively through the connecting through hole of the upper bending part 51 that connects channel-section steel 5, the central through bore of cushion pad 6, the second waist typed through hole 111 and the first waist typed through hole 41, its top is bolted with set screw nut 9, set screw nut 9 is pressed against on the upper plane of reinforced block 4.
Be fixed with regulating block 10 on the upper plane of described base plate 11, be bolted with hand tighten screw 20 on regulating block 10, the top of hand tighten screw 20 faces toward set screw nut 9 through regulating block 10, the tail end of hand tighten screw 20 is that hand is twisted section 21, and the length direction that moves axially direction and the first waist typed through hole 41, the second waist typed through hole 111 of hand tighten screw 20 is same direction.
