Abstract

The invention relates to a dust collection hopper structure used for a ship unloader. The dust collection hopper structure used for the ship unloader comprises a hopper, wherein a rectangular wind shield wall which is formed by four wind shield wall bodies is connected to the upper portion of the hopper, dust collection ports which are connected with dust collection equipment are symmetrically formed in each wind shield wall body, a plurality of supporting rib plates are connected to the inner wall of each wind shield wall body, the upper edge of each supporting rib plate is connected to a first steel plate, the lateral side of each supporting rib plate is connected to a second steel plate, an inverted-U-shaped cavity with an opening facing downwards is formed by the first steel plates, the second steel plates, the supporting rib plates and the inner walls of the wind shield wall bodies, and a distribution grating is installed in the hopper and is located on the lower portion of the inverted-U-shaped cavity. According to the dust collection hopper structure used for the ship unloader, due to the fact that the dust collection holes are symmetrically formed in each wind shield wall body and the inverted-U-shaped cavity which is provided with the opening facing downwards and is formed by connection of the supporting rib plates and the steel plates, dust flying along the wall of the hopper and the wind shield wall bodies can be well collected and circulates in the supporting rib plates with kidney-shaped holes, the dust is prevented from overflowing again, the dust collection effect is greatly improved, and dust collection efficiency is improved.

Description

A kind of hopper construction of gathering dust for ship unloaders

Technical field

The present invention relates to cleaner, relate in particular to a kind of material mouth structure that gathers dust for ship unloaders.

Background technology

Along with China's economic development, the advancing by leaps and bounds of port construction progress, the demand of ship unloaders is increasing.For the needs of protection of the environment, at the hopper place of ship unloaders, must take dust arrester, in order to know the dust producing when the discharging.At present, the cleaner of ship unloaders adopts water spray dedusting and depression dust-removing, the mounting structure of water spray dedusting is to install nozzle additional in the keep out the wind surrounding of wall of hopper, by nozzle, spray water smoke compacting dust and overflow hopper, but the mode of this water spray dedusting easily makes the caking property of material strengthen after meeting water, causes the putty at hopper outlet place.

The mounting structure of depression dust-removing is to install blower fan and dust collecting box additional in hopper outside, and open the mouth that gathers dust on bucket wall or windbreak, inspiration dust reclaims resource, but the mode of this depression dust-removing is owing to opening wide the excessive and dust excessive velocities of kicking up and cause dust collection effect undesirable in the region of gathering dust.

Summary of the invention

The applicant, for these shortcomings in above-mentioned existing production, provides a kind of material mouth structure that gathers dust for ship unloaders, has dust collection effect good, reduces the advantage of dirt body spill-out.

The technical solution adopted in the present invention is as follows:

A kind of material mouth structure that gathers dust for ship unloaders, comprise hopper, the top of hopper connects the rectangle being connected to form by the four windbreaks wall that keeps out the wind, the symmetrical mouth that gathers dust being connected with dust-collecting equipment that has on described each windbreak, the inwall of each windbreak connects polylith bearing rib, the top of each bearing rib connects the first steel plate, and the side of each bearing rib connects the second steel plate, and the inwall of the first steel plate, the second steel plate, bearing rib and windbreak forms " U " shape cavity that Open Side Down; Sub-material grid is installed in described hopper, and is positioned at the described bottom of " U " shape cavity.

Its further technical scheme is:

Described the first steel plate and the second steel plate are respectively 4, and 4 blocks of first steel plates and 4 blocks of second steel plates are connected to form rectangle framework from beginning to end;

The inwall upper support gusset quantity that is positioned at a side block brattice is 4, and the total quantity of bearing rib is 16;

Described bearing rib is polygon, and on bearing rib, also having can be for the mounting hole of dust circulation.

Beneficial effect of the present invention is as follows:

The present invention is simple in structure, by symmetry on surrounding windbreak, have the hole of gathering dust, arrange by bearing rib, steel plate simultaneously and be connected to form the inverted U-shaped cavity that Open Side Down, by sub-material grid device in hopper, and be positioned at the bottom of inverted U-shaped cavity, make the dust of kicking up along bucket wall and windbreak there is obvious gathering effect, dust circulates in having the bearing rib of mounting hole, prevent again overflowing of dust, by the dust sucting pipeline being connected with the mouth that gathers dust, enter external dust-collecting equipment, greatly improve dust collection effect, improved dust-collecting efficiency.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.

As shown in Figure 1, Figure 2 and Figure 3, the present invention includes hopper 7, the top of hopper 7 connects the rectangle being connected to form by four windbreaks 1 wall that keeps out the wind, three Height of Wind Break Wall that are positioned at land side are greater than a windbreak that is positioned at water side, the symmetrical mouth 101 that gathers dust being connected with the joint 9 of dust-collecting equipment that has on each windbreak 1, the inwall of each windbreak 1 connects polylith bearing rib 2, as shown in figure 10, bearing rib 2 is polygon, and on described bearing rib 2, also having can be for the mounting hole 201 of dust circulation.The quantity that is positioned at the inwall upper support gusset 2 of a side block brattice 1 is 4, as shown in Figure 3, the total quantity of bearing rib 2 is 16, as shown in figure 10, the top of bearing rib 2 connects the first steel plate 5, the side of bearing rib 2 connects the second steel plate 6, the inwall of the first steel plate 5, the second steel plate 6, bearing rib 2 and windbreak 1 forms " U " shape cavity that Open Side Down, the first steel plate 5 and the second steel plate 6 are respectively 4, and 4 blocks of first steel plates 5 and 4 the second steel plate 6 head and the tail are connected to form rectangle framework.As shown in Figures 4 to 7, sub-material grid 3 is installed in hopper 7, and is positioned at the described bottom of " U " shape cavity.

As shown in Fig. 3, Fig. 7, at the two ends that are positioned at the windbreak 1 of water side, have in mouthful 101 installing holes that are communicated with that gather dust, the pipeline 4 that device is connected with outside dust-collecting equipment in installing hole.

Specific works process of the present invention is as follows:

As Fig. 8, shown in Fig. 9, after the grab bucket crawl material of ship unloaders, grab bucket moves to the top blowing of hopper 7, material is fallen by eminence and the sub-material grid 3 in hopper 7 inside contacts, the dust of kicking up, dust spreads to surrounding in the unknown contacting with sub-material grid 3, and raise up along the inwall of bucket wall and windbreak 1, enter above-mentioned " U " shape inside cavity, as shown in figure 10, dust is in the interior circulation of mounting hole 201 of each bearing rib 2, and the mouth 101 that gathers dust being connected by the joint 9 with dust-collecting equipment enters dust-collecting equipment, the collection efficiency of dust is higher, diffusion and the spill-over effects of dust have clear improvement, protection of the environment, economize on resources.

In Fig. 8, Fig. 9, the direction of arrow represents blanking direction, and in Figure 10, arrow square chest represents the circulating direction of dust in the mounting hole 201 of bearing rib 2.

More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention is referring to claim, and without prejudice to basic structure of the present invention in the situation that, the present invention can do any type of modification.
