Description

Technical Field

[0001] This application relates to a sealing grid for a dust removal loading hopper, and more particularly to a sealing grid for a dust removal loading hopper. Background Technology

[0002] The mobile dust removal loading hopper (referred to as the environmental protection hopper) is a complete piece of equipment used in ports for packaging biomass fuel.

[0003] In related technologies, environmentally friendly hoppers are typically equipped with an air dust removal device at the top to absorb dust escaping from the hopper and the telescopic chute. An electro-hydraulic valve is located at the bottom of the hopper, opening for discharging and closing for storing material. This valve connects to the telescopic chute, which can extend and retract to prevent dust from escaping during material loading. The environmentally friendly hopper is equipped with a driver's cab and remote control for hopper operation.

[0004] Although the aforementioned environmentally friendly hoppers are equipped with dust collection devices such as air dust removal devices, the inlet of their loading hoppers is usually open. Dust generated during unloading can easily be discharged directly from the inlet, thus affecting the dust removal effect of the environmentally friendly hoppers. Summary of the Invention

[0005] In order to improve the dust removal effect of the environmental protection funnel, this application provides a sealing grid for the dust removal loading funnel.

[0006] The sealing grid for a dust removal loading hopper provided in this application adopts the following technical solution:

[0007] A sealing grid for a dust removal loading hopper includes a main beam fixedly connected to the opening of the hopper. Both ends of the main beam are fixedly connected to grid bodies. The two grid bodies completely cover the opening of the hopper, and both grid bodies are fixedly connected to the inner wall of the hopper. The lower end of each grid body is inclined towards one side of the main beam. The projection of the inclined section of the grid body towards the main beam in a direction perpendicular to the ground blocks the projection of the opening at the top of the grid body in a direction perpendicular to the ground. A protective mechanism is provided at the top of the grid body to protect it.

[0008] By adopting the above technical solution, the main beam can be set to reinforce and fix the grid body on both sides. The material can enter the funnel through the grid body. The flue gas generated by the material falling into the funnel will be blocked from spreading directly upward due to the inclined setting of the lower part of the grid body, thereby reducing the speed at which the flue gas overflows into the funnel. This allows the dust removal device at the funnel to have more time to absorb the flue gas, thereby greatly improving the dust removal effect of the flue gas environmental protection funnel.

[0009] Optionally, the protective mechanism includes a plurality of protective plates arranged parallel to the main beam, each protective plate corresponding one-to-one with the longitudinal bars of the grid body, and a fixing component for fixing the protective plate to the grid body is provided between the protective plate and the grid body. The protective mechanism also includes a plurality of protective strips arranged perpendicular to the main beam, and the plurality of protective strips are equidistantly arranged along the transverse bars of the grid body.

[0010] By adopting the above technical solution, the longitudinal bars of the grid body can be protected by the protective plate, reducing the wear and tear caused by materials. The transverse bars of the grid body can be protected by the protective strip, reducing the wear and tear caused by materials.

[0011] Optionally, the protective strip is made of rubber, and a snap-fit ​​groove is provided at the lower end of the protective strip. The protective strip is snapped onto the horizontal grid bar of the grille body through the snap-fit ​​groove.

[0012] By adopting the above technical solution, the protective strip can be detachably fixed to the horizontal grid in the grid body through the snap-fit ​​groove, which facilitates the replacement of the protective strip.

[0013] Optionally, an adhesive storage tank is provided on the inner wall of the snap-fit ​​groove, and industrial adhesive for connecting the two is provided between the adhesive storage tank and the transverse grid bars of the grid body.

[0014] By adopting the above technical solution, industrial adhesive can be placed in the adhesive storage tank, and the protective strip can be bonded to the transverse grid strips in the grid body using the industrial adhesive.

[0015] Optionally, the fixing component includes countersunk bolts threaded onto the sidewall of the protective plate, the countersunk bolts passing through the sidewall of the protective plate and threaded onto the longitudinal bars in the grid body.

[0016] By adopting the above technical solution, when the protective plate is damaged, the countersunk bolt can be rotated to disengage the shank from the longitudinal grid strip in the grid body, thereby allowing the protective plate to be disassembled and replaced.

[0017] Optionally, the protective plate has a groove on one side facing the longitudinal bars of the grille body, and the upper part of the longitudinal bars in the grille body is engaged in the groove.

[0018] By adopting the above technical solution, during installation, the position of the protective plate on the longitudinal bars in the grille body can be initially restricted by the groove.

[0019] Optionally, the upper end of the transverse grid bars in the grid body is provided with multiple notches, the notches are located on both sides of the longitudinal grid bars in the grid body, and the side wall of one side of the protective plate is placed in the notch and engaged with the notch.

[0020] By adopting the above technical solution, the protective plate can be initially limited by setting a notch, and the stability of the protective plate at the notch can be improved.

[0021] Optionally, the grid body is welded to the inner wall at the opening of the funnel.

[0022] By adopting the above technical solution, the grid body can be firmly fixed on the funnel.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting the main beam, the grid body on both sides can be reinforced and fixed. The material can enter the funnel through the grid body. The flue gas generated by the material falling into the funnel will be blocked from spreading directly upward due to the inclined setting of the lower part of the grid body, thereby reducing the speed of flue gas overflowing into the funnel. This allows the dust collection device at the funnel to have more time to absorb the flue gas, thereby greatly improving the dust removal effect of the flue gas environmental protection funnel.

[0025] 2. When the protective plate is damaged, the countersunk bolts can be rotated to disengage the shank from the longitudinal grid bars in the grid body, thereby allowing the protective plate to be disassembled and replaced.

[0026] 3. A notch can be set to initially limit the protective plate and improve its stability at the notch. Attached Figure Description

Detailed Implementation

[0031] The following is combined with Figure 1 -Appendix Figure 3This application will be described in further detail below.

[0032] This application provides a sealing grid for a dust removal loading hopper, as shown in the embodiments below. Figure 1 and Figure 2 The system includes a main beam 1 fixedly connected to the funnel opening. The main beam 1 can be made of various materials, such as stainless steel or aluminum alloy, and possesses high strength and corrosion resistance. The cross-section of the main beam 1 can be rectangular, circular, or other shapes; in this embodiment, the cross-section of the main beam 1 is set to triangular to adapt to different installation requirements.

[0033] Both ends of the main beam 1 are fixedly connected to a grid body 2. The two grid bodies 2 completely cover the opening of the funnel, and both grid bodies 2 are welded to the inner wall of the funnel. The grid body 2 consists of multiple longitudinal and transverse grid bars. The longitudinal grid bars can be made of high-strength materials such as stainless steel or carbon steel, which have good bending resistance and corrosion resistance. The transverse grid bars can also be made of stainless steel or carbon steel to ensure the stability of the entire grid body 2. The longitudinal and transverse grid bars can be fixed together by welding, bolting, or other methods to form a solid whole. The lower end of the grid body 2 is inclined towards one side of the main beam 1, which allows the dust to be blocked by the grid body 2 during the falling process, reducing the dust dispersion.

[0034] The projection of a section of the grille body 2 inclined toward the main beam 1 in the direction perpendicular to the ground blocks the projection of the opening at the top of the grille body 2 in the direction perpendicular to the ground. The inclined design in this sealed grille body 2 reduces the possibility of dust directly escaping from the grille body 2.

[0035] The upper part of the grid body 2 is provided with a protective mechanism 3 for protecting the grid body 2. The protective mechanism 3 includes a plurality of protective plates 31 arranged parallel to the main beam 1. The protective plates 31 correspond one-to-one with the longitudinal bars of the grid body 2. A fixing component 32 for fixing the protective plates 31 to the grid body 2 is provided between the protective plates 31 and the grid body 2.

[0036] Reference Figure 1 , Figure 2 and Figure 3 The protective plate 31 can be made of metal materials, such as stainless steel or aluminum alloy, which have high strength and corrosion resistance. A groove 311 is formed on the side of the protective plate 31 facing the longitudinal bars of the grille body 2, and the upper part of the longitudinal bars in the grille body 2 is engaged in the groove 311. The design of the groove 311 increases the contact area between the protective plate 31 and the longitudinal bars, improving the stability of the fixation. The shape and size of the groove 311 should match the cross-section of the longitudinal bars to ensure that the protective plate 31 can be firmly engaged with the longitudinal bars. The length and width of the protective plate 31 should match the longitudinal bars of the grille body 2 to ensure that it can completely cover the longitudinal bars and provide protection.

[0037] The fixing component 32 includes countersunk bolts 321 threaded onto the sidewall of the protective plate 31. The countersunk bolts 321 pass through the sidewall of the protective plate 31 and are threaded onto the longitudinal bars in the grid body 2. The countersunk bolts 321 should be selected to match the material of their fixing parts to ensure reliable connection. The length of the countersunk bolts 321 should be appropriate to ensure a firm fixation without affecting the installation and removal of the protective plate 31.

[0038] The protective strip 33 is made of rubber, and a snap-fit ​​groove 331 is provided at its lower end. The protective strip 33 is snapped onto the transverse bars of the grid body 2 through the snap-fit ​​groove 331. The rubber protective strip 33 has good elasticity and wear resistance. The shape and size of the snap-fit ​​groove 331 should match the cross-section of the transverse bars to ensure that the protective strip 33 can be firmly snapped onto the transverse bars. A glue storage groove 3311 is provided on the inner wall of the snap-fit ​​groove 331, and the glue storage groove 3311 is set along the length of the protective strip 33. Industrial adhesive is provided between the glue storage groove 3311 and the transverse bars of the grid body 2 for connecting the two. The industrial adhesive should be selected with good adhesion and weather resistance to ensure a firm and reliable connection between the protective strip 33 and the transverse bars. The design of the glue storage groove 3311 can increase the contact area of ​​the industrial adhesive and improve the stability of the connection.

[0039] Multiple notches 21 are provided at the upper ends of the transverse grid bars in the grille body 2. The notches 21 are located on both sides of the longitudinal grid bars in the grille body 2. One side wall of the protective plate 31 is placed in the notch 21 and snaps into it. The design of the notch 21 can increase the contact area between the protective plate 31 and the transverse grid bars, thereby improving the stability of the fixation. The shape and size of the notch 21 should match the side wall of the protective plate 31 to ensure that the protective plate 31 can be firmly snapped into the transverse grid bars.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
