Field of the Invention The present invention relates to an inspection port structure of a device for handling powder and granular material, and particularly to a device for generating dust such as a ceramic industry and other mixers. Fire resistant to prevent dust and dust leakage
It relates to the inspection port structure of equipment for handling powdery and granular materials . 2. Description of the Related Art FIG. 2 shows a side view of a casing 2 of a powder and granular material handling device 1 such as a mixer for stirring powder and granular materials such as refractories.
Although the inspection port 3 is attached as shown in FIG. 3, powder particles 4 generated inside or powder particles 4 directly dropped on the inspection port 3 accumulate on the flange portion 5 below the inspection port 3. [0003] The granular material deposited at the lower part of the inspection port 3 is
Every time the operator opened and closed the inspection lid 6 for the internal inspection, the operator spilled out and scattered. For this reason, a problem has arisen because the powdery particles scatter from the inspection port, which should be a sealing mechanism, to the work place. In particular, there is a problem in the equipment for handling granular materials which is commercially available as an inspection door, since the space where the granular material is deposited at the inspection port is large. [0004] The inspection port of the powder handling equipment such as a mixer has a role of sealing the equipment, and therefore requires a sealing material 7 such as packing. A space for inserting the packing is required as shown in FIG. 3, and a casing 2 having a predetermined thickness is required for keeping the packing in contact with the packing to keep it airtight. It is difficult to completely eliminate the space to be deposited. Means for Solving the Agenda The present invention has been made in view of the above points, and in order to solve the above-mentioned problems, equipment for handling powder and granular materials for refractories, such as a mixer, has been proposed. in the peripheral portion sealed to access port granule handling equipment refractories were provided with openably access hole inspection lid to inspect the inside, from the upper end to the inside of the inspection lid access hole Prevents accumulation of granular material bent into L-shape with steeply inclined surface inward along the lower end
Together when mounting the plate so as to cover the sealing material of the lower portion
In addition, the granular material slips on the surface of the above-mentioned
An object of the present invention is to provide an inspection port structure of a refractory powder / particle handling device, which is characterized by being coated with a powder / particle adhesion inhibitor . [0006] In accordance with the present invention, it to the inside of the inspection lid of inspection opening
L of the steeply inclined surface inward from the upper end to the lower end of
By the granular material deposition preventing plate is bent into the form attached so as to cover the sealing material of the lower portion, granules or generated in the apparatus, the reinforcing particulate material to fall when turned the inspection lid To
It can be prevented from sliding down along the powder / particle accumulation preventing plate which also serves as a deposit at the lower seal portion of the inspection port. So the point
The inspection port can play the role of sealing the equipment, and the internal inspection
Even if the inspection lid is opened, the powder and granules spill out to the workplace.
Can prevent splashing and maintain a good working environment.
You. [0007] In addition, the powder is deposited
Coating the granular material anti-adhesive agent so that the particles are easy to slip
By this, it is possible to prevent the powder
The fire powder drops without adhering to the surface, and the inspection lid is quickly opened.
Ensures that granules do not fall into the workplace even when opened quickly
it can. Hereinafter, the present invention will be described based on embodiments. FIG. 1 shows an inspection port of an embodiment of the present invention. The powder handling equipment 1 such as a mixer is covered with a casing 2 which also serves as a protective fence for safety and a dust cover for sanitation. FIG. 1 shows a side view of the casing 2.
The inspection port 3 of a predetermined size is arranged as shown in FIG. 1 and the state inside the device can be inspected by opening the inspection lid 6. For example, in the case of a mixer, the kneading state of the refractory powder and the abrasion state and the mounting state of the stirring blade can be visually inspected. As shown in FIG. 1, the inspection lid 6 of the inspection opening 3 has an L-shaped cross section bent inside so as to be in contact with a sealing member 7 such as a packing on the inner peripheral portion. A substantially wedge-shaped powder / particle accumulation preventing plate 8 is attached so as to cover the lower seal material 7 so that the powder does not accumulate, and reinforce the inspection lid 6 so as not to be deformed. Like that. As shown in FIG. 1, an ultra-high molecular weight polyethylene plate or a coating material powder adhesion preventing material 9 is attached to the surface of the powder accumulation preventing plate 8 as shown in FIG. The particles scattered on the body accumulation preventing plate 8 are prevented from falling and accumulating without adhering to the surface. Therefore, if the inspection lid 6 is tightly fastened to the inspection opening 3 of the powder handling equipment 1 such as a mixer by bolts or the like, the inner peripheral portion of the inspection opening 3 as shown in FIG. Inspection lid 6 is provided on the lower seal material 7 where powders are likely to accumulate.
The powder / particles accumulation preventing plate 8 protruding from the cover 8 covers the powder / particles to prevent the accumulation of the particles. Therefore, even if the inspection lid is opened during inspection,
The granular material does not spill outside from the seal portion, and it is possible to prevent the granular material from scattering to the work place and damaging the environment. For example,
Conventionally, the opening and closing of the inspection opening causes the powder to be released at approximately 1.
2Kg was also taken out, but by the present invention it was about 0.
Only 1 kg flowed out, which was reduced to 1/12. Further, the particulate matter deposition preventing plate is attached as a steeply inclined surface as described above, and the particulate matter does not adhere because the particulate matter adhesion preventing material is attached to the surface thereof. Even if it is opened, it is possible to prevent the granules from falling into the work place. In addition, it is preferable that the inclination angle of the granular material deposition prevention plate is a steep inclined surface at least equal to or greater than the angle of repose. Further, the inspection lid is moved from the upper end to the lower end.
Therefore, the inspection lid is reinforced by attaching the powder-particles deposition prevention plate having the L-shaped cross section , and the inspection lid is preferably prevented from being deformed. In the above embodiment, the wedge-shaped particle accumulation preventing plate having a cross section is attached to the inspection lid along the upper end to the lower end of the inspection opening. However, it can be appropriately attached based on the spirit of the present invention. It is. In the above description, the apparatus for handling powder and granules of the mixer has been described. However, the invention can be similarly applied to the inspection port of the apparatus for handling powder and granules of crushers, hoppers, and other refractories . As described above, according to the present invention, if an inspection port is provided, powder particles accumulate on the sealing portion of the flange portion of the inspection port, and if the inspection lid is opened, the powder particles will be opened. Despite spilling to the outside workplace and easy to scatter, the powder accumulation prevention plate attached to the inspection lid can effectively prevent the accumulation of powder at the inspection port, Can be prevented from spilling out into the workplace. With the accumulation of powder
The inspection cover can be reinforced by the prevention plate, and the durability can be improved . Soshi
Therefore, the powder particles may slip on the surface of the powder
By coating the powder adhesion prevention agent as
The refractory powder particles scattered on the powder accumulation prevention plate
Drops without adhering to the surface, even if the inspection lid is opened quickly
Granules can be reliably prevented from falling to the workplace.
