Description
Technical Field
The utility model belongs to the dust hood field, concretely relates to closed material transfer chain dust hood.
Background
In industrial production, it is common to use a conveyor to directly operate materials, a large amount of dust can be escaped to an external production workshop due to instability of a conveying belt in the transportation process of the materials, the particle size of the dust is small, the dust is easy to be absorbed into human bodies, and the harm to the health of people is great. At present, a method adopted for preventing dust from escaping is to add a top plate and two side plates to form a closed material conveying line. But has the disadvantages that: in the closed material conveying line, in order to ensure the normal operation of the conveying line, gaps are reserved between the two side plates and the conveying line, and dust can be dissipated.
SUMMERY OF THE UTILITY MODEL
The utility model discloses plan from practicing thrift the cost, the loss of the dust that arouses when preventing closed material conveying line transportation.
Therefore, the utility model discloses the technical scheme who adopts does: the utility model provides a closed material transfer chain dust cage, includes closed material conveyer belt and dust cover, the middle section top at closed conveyer belt is installed to the dust cage, closed material conveyer belt includes the curb plate of roof and both sides, the dust cage includes dustcoat, dustcoat support frame, dust collection box, dust absorption return bend, filter cloth, the dustcoat suit is on the dustcoat support frame, and open at the upper segment of dustcoat has the negative pressure hole, and open at the upper segment of one side curb plate has the fresh air inlet, the fresh air inlet is at the homonymy with the negative pressure hole, the roof is opened there is the dust absorption hole, the dust absorption hole is opened in the one side of keeping away from the fresh air inlet, the one end of dust absorption return bend is installed in dust absorption hole top, and the other end of dust absorption return bend just to the negative pressure hole and open jaggedly, the dust collection box.
Preferably, the outer cover supporting frame is composed of an upper annular steel bar, a lower annular steel bar and at least three vertically-supported steel bars, and the outer diameter of each annular steel bar is not larger than the width of the top plate.
Further preferably, the outer cover is made of a coated fabric. The coating fabric is wind-tight and dust cannot penetrate through the coating fabric, so that wind can only follow a fixed route.
Preferably, the dust collection bent pipe is integrally shaped like L, the inner diameter of the dust collection bent pipe is consistent with the aperture of the dust collection hole, the notch is formed in the lower portion of the dust collection bent pipe, the inner diameter of the dust collection bent pipe is consistent with the aperture of the dust collection hole so that dust can smoothly enter the dust collection bent pipe and cannot be collected on the top plate, and the notch is formed in the lower portion of the dust collection bent pipe so that the dust can fall into the integration box.
More preferably, the dust collection box is cylindrical, and the inner diameter of the dust collection box is larger than the sum of the length of the notch and the thickness of the filter cloth. Prevent that the dust from falling outside the collection box.
When the negative pressure fan is used, the negative pressure port of the negative pressure fan extends into the negative pressure hole and is fixed, and the negative pressure fan works along with the work of the conveying belt. When the negative pressure fan works, air enters from the air inlet hole, carries dust to enter the dust collection elbow through the dust collection hole, then enters the negative pressure fan through the filter cloth along the dust collection elbow, and the dust falls into the dust collection box under the action of gravity because the dust cannot penetrate through the filter cloth.
The utility model has the advantages that: the structure is simple and reasonable; the dust collection cover is arranged at the initial section of the closed material conveying belt, so that dust can be effectively prevented from escaping, and a cleaner and more sanitary workshop environment is created; meanwhile, the dust collection cover needs a small air inlet amount, so that the cost is saved; because the dust collection cover is internally provided with the integration box, dust can be collected and treated.
Drawings

Fig. 2 is a cross-sectional view a-a of fig. 1.
Detailed Description
The invention will be further described by way of examples with reference to the accompanying drawings:
as shown in fig. 1 and 2, a dust collection cover of a closed material conveying line comprises a closed material conveying belt and a dust collection cover, wherein the dust collection cover is arranged above the middle section of the closed conveying belt.
The closed material conveying belt mainly comprises a top plate 2 and side plates 1 on two sides, and the dust collection cover mainly comprises an outer cover 3, an outer cover support frame 4, a dust collection box 6, a dust collection bent pipe 5 and filter cloth 7.
The suit of dustcoat 3 is on dustcoat support frame 4, the upper segment of dustcoat 3 is opened there is negative pressure hole 3a, the upper segment of one side curb plate 1 is opened there is fresh air inlet 1a, fresh air inlet 1a and negative pressure hole 3a are at the homonymy, roof 2 is opened there is dust absorption hole 2a, dust absorption hole 2a is opened in the one side of keeping away from fresh air inlet 1a, the one end of dust absorption return bend 5 is installed in dust absorption hole 2a top, the other end of dust absorption return bend 5 just to negative pressure hole 3a and open jaggedly 5a, dust collection box 6 is installed in jaggedly 5a below, filter cloth 7 is vertical to be installed between dust absorption return bend 5 and.
Preferably, the housing support frame 4 is composed of upper and lower ring-shaped reinforcing bars having an outer diameter not greater than the width of the top plate and at least three reinforcing bars supported vertically.
