Description

Technical Field

[0001] The present invention relates to the technical field of dust removal for inland river ships, and more specifically, it relates to a dust collector for bulk cement ships. Background Art

[0002] In the middle and lower reaches of the Yangtze River and large river basins, there are a large number of bulk cement ships in operation. The cement production capacity in the Yangtze River Delta is 330 million tons, accounting for half of the country's total. Long-distance bulk cement transportation is almost entirely achieved by ship transportation.

[0003] During the cement loading and unloading process, when pneumatic conveying equipment is used at the cement plant warehouse terminal to load and unload cement into the shipborne cement tank, a large amount of gas mixed with the cement is discharged from the outlet of the tank. The discharged gas mixed with a large amount of cement-containing dust will pollute the air or float into the river. The long-term accumulation of cement in the river will cause siltation.

[0004] To solve the above problems, large dust collectors on the market can be used to achieve dust treatment, and there is also the cooperation of power supply and compressed air, which increases the operation cost of the shipowner. The installation volume of this kind of equipment is relatively large and will occupy a large part of the hull space. Therefore, it is relatively difficult to promote and apply it to inland river ships. Summary of the Invention

Detailed Embodiment

[0034] Refer to Figures 1 to 6 To further describe the embodiments of the present invention.

[0035] The specific structure of this embodiment includes a housing 1 and a dust removal unit 5.

[0036] The housing 1 has a cavity. An air inlet and an air outlet are provided on the housing 1. An intake pipe 111 is connected to the air inlet, and is docked with the tank outlet of the ship through the intake pipe 111. An exhaust pipe 112 is connected to the air outlet.

[0037] The cavity includes an interconnected intake chamber 101 and purification chamber 102. A baffle plate 3 is provided in the intake chamber 101.

[0038] One end of the baffle plate 3 is fixed to the inner wall of the intake chamber 101, and the other end extends into the purification chamber 102. The baffle plate 3 is arc-shaped. An opening 30 is provided on the side of the baffle plate 3 close to the purification chamber 102.

[0039] The air inlet is opened in the air inlet chamber 101, and the exhaust port is opened at the top inside the purification chamber 102. A support plate body 4 is provided inside the purification chamber 102.

[0040] The dust removal unit 5 is placed inside the purification chamber 102. The dust removal unit 5 includes a frame body 51 and six cloth bag assemblies 6 placed on the frame body 51. The frame body 51 is supported by the support plate body 4. The frame body 51 is directly placed on the support plate body 4, facilitating the disassembly and assembly of the frame body 51 from the purification chamber 102.

[0041] The cloth bag assembly 6 includes a framework and a dust removal cloth bag 62 placed on the framework. There are through holes on the frame body 51 for the dust removal cloth bag to pass through.

[0042] The framework includes six guide rods 60 and a limit seat 7. The guide rods 60 are hollow.

[0043] The limit seat 7 includes a chassis 71 and a pressing plate 72. The centers of the chassis 71 and the pressing plate 72 have mutually communicating central holes, so that after the dust removal cloth bag extends out from the central hole of the chassis 71, it is folded outwards and is squeezed by the pressing plate 72.

[0044] Six docking holes 701 for threaded connection of the first ends of the guide rods 60 are provided on the chassis 71, and there are hole positions 50 on the frame body 51 for the guide rods 60 to pass through.

[0045] Six pin posts 721 for squeezing the dust removal cloth bag into the ports of the guide rods 60 are provided on the pressing plate 72.

[0046] A sleeve part 64 for the end of the guide rod 60 to pass through is provided outside the dust removal cloth bag 62. The bottom end of the sleeve part 64 is folded with a pressed part, and a connecting body 64 for squeezing the pressed part is connected to the end of the guide rod 60.

[0047] When installing the dust removal cloth bag and the framework: First, place the chassis 71 at the corresponding position on the frame body 51. Then, the port of the dust removal cloth bag passes through the through hole of the frame body 51, and then it is folded so that it covers the outer end face of the chassis 71. The six guide rods 60 are penetrated upward from the bottom ends of the six sleeve parts of the dust removal cloth bag, so that the ends of the guide rods 60 extend into and are screwed tightly with the docking holes 701 on the chassis 71. Then, the bottom of the sleeve part is folded and stuffed into the guide rod 60. The connecting body 64 made of rubber is stuffed into the guide rod 60 to squeeze the pressed part stuffed into the guide rod 60. The connecting body 64 is frustum-shaped, and the more it is squeezed into the guide rod 60, the more stable the pressed part is in the guide rod 60. Finally, the pressing plate 72 is pressed on the chassis 71. During this period, the pin posts on the pressing plate 72 squeeze the dust removal cloth bag on the chassis 71, so that it is stuffed into the guide rod 60. The pin posts are also frustum-shaped, and the more they are squeezed inward, the more stable the connection between the dust removal cloth bag and the chassis 71 is. Moreover, both the pressing plate 72 and the chassis 71 have magnetism, so that when the chassis 71 and the pressing plate 72 clamp the dust removal cloth bag, the dust removal cloth bag can be more stable.

[0048] A doorway is provided at a position on the housing 1 corresponding to the purification chamber 102. A door frame 81 is provided on the doorway. A cover door 8 is movably connected to the door frame 81. The cover door 8 is movably connected to the door frame 81 through a transmission structure. A handle is provided on the end face of the cover door 8.

[0049] The transmission structure includes a rotating shaft assembly and two rocker arms in an upper and lower relationship.

[0050] One ends of the upper rocker arm 91 and the lower rocker arm 92 are respectively rotatably connected to the upper and lower edge walls in the middle of the door frame 81, and the other ends are respectively rotatably connected to the upper and lower edge walls on the outside of the cover door 8. Sleeve parts are provided at the ends of the upper rocker arm 91 and the lower rocker arm 92. A pin shaft extending into the sleeve parts is provided on the cover door 8, thus realizing a rotational connection relationship.

[0051] The rotating shaft assembly includes a shaft rod 93 and two pull rods 94 respectively connected to both ends of the shaft rod 93. The other ends of the pull rods 94 are rotatably connected to the upper and lower edge walls in the middle of the cover door 8. The pull rods 94 are in an L shape. The shaft rod 93 is connected to the corner of the pull rod 94. Sleeve parts are provided at both ends of the pull rod 94. A pin shaft sleeved by the sleeve parts is provided on the cover door 8, realizing relative rotation.

[0052] When pulling the cover door 8, the cover door 8 first moves linearly outward in the circumferential direction and then displaces to one side. In this way of opening the door, compared with the traditional single-side hinge door opening method, after the cover door 8 is opened, it can be translated to one side, so that the cover door 8 and the door frame 81 are in a parallel state, ensuring the stability of the cover door 8 in the prohibited state, thus facilitating the disassembly and installation of the dust removal component from the purification chamber 102. Moreover, since the air pressure in the purification chamber 102 is greater than the external air pressure, when the traditional single-side hinge door is opened, it is in a state of flipping outward on one side.

[0053] At the moment when the door is opened, due to the air pressure difference, the dust collection box 120 for collecting dust in the purification chamber 102 will have a dust-raising situation. By opening the current cover door 8 outward and then obliquely displacing, the dust-raising situation can be avoided.

[0054] A material receiving unit 10 is provided at the bottom of the purification chamber 102. The material receiving unit 10 is placed below the cloth bag assembly 6.

[0055] The material receiving unit 10 includes a material box 120 and a material cover 110. The material cover 110 is hinged to one end of the material box 120.

[0056] On the inner wall of the cover door 8, there is a blocking rod 82 for blocking the material cover 110, so that when the cover door 8 is closed, the material cover 110 leans against the inner wall of the purification chamber 102; when the cover door 8 is opened, the material cover 110 automatically covers the material box 120. There is a magnet inside the blocking rod, and the material rod is magnetic. When the cover door 8 moves, the blocking rod detaches the material cover 110 from leaning on the purification chamber 102 by magnetic attraction. Finally, when the blocking rod moves away from the material cover 110, the material cover 110 falls onto the material box 120, partially covering the material box 120.

[0057] The area of the material cover 110 is 1 / 2 of the area of the material box 120. In order to be able to cooperate to cover a part of the material box 120 and reduce the situation of dust raising when the cover door 8 is opened.

[0058] There is a cavity formed between the baffle 3 in the air inlet chamber 101 and the bottom of the air inlet chamber 101. The cavity is communicated with the purification chamber 102. One side of the cavity has an opening. A sliding seat 13 is slidably connected in the cavity. A handle is provided on the outer wall of the sliding seat 13, and a heating unit 14 that can consume oxygen is provided in the sliding seat 13.

[0059] The heating unit 14 can be a combustible object, and the combustible object can be solid alcohol or a portable component such as a candle.

[0060] Working principle: By igniting the candle or alcohol in the sliding seat 13, the oxygen in the air inlet chamber 101 will be consumed. And because the temperature of the air inlet chamber 101 rises, the dust containing cement quickly enters the air inlet chamber 101 through the air inlet pipe, and then passes through the baffle 3 below the air inlet chamber 101. Since the channel connecting the air inlet chamber 101 and the purification chamber 102 becomes narrower due to the setting of the arc-shaped baffle 3, the flow rate of the gas passing through will be further accelerated. Finally, the dust will come out through the dust removal cloth bag, come out from the upper port of the dust removal cloth bag and finally be discharged from the exhaust port. The above principle adopts the principle of a chimney, and no power source and gas source need to be set up during the whole process.

[0061] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
