Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cement bulk workshops, specifically to a closed structure for cement bulk workshops. Background Technology
[0002] Cement: A powdered hydraulic inorganic binder. When mixed with water, it forms a paste that hardens in air or water, and firmly binds materials such as sand and stone together. Early mixtures of lime and volcanic ash were very similar to modern lime-volcanic ash cement. Concrete made with this binder not only has high strength after hardening but also resists erosion from fresh or salt water. For a long time, it has been widely used as an important binder in civil engineering, water conservancy, and national defense projects.
[0003] Bulk cement refers to cement that is transported directly from the factory to a transfer station or user without any packaging after production, using specialized vehicles. China's bulk cement industry began in the 1950s and entered its peak promotion period in this century, becoming an important part of energy conservation efforts.
[0004] Currently, in bulk cement workshops, dust generated during loading can easily escape from the workshop's inlet and outlet, polluting the surrounding environment. Therefore, the applicant has developed a closed structure for bulk cement workshops to solve the aforementioned technical problems during actual production. Utility Model Content
[0005] In view of the above-mentioned technical deficiencies, the purpose of this utility model is to provide a closed structure for cement bulk workshops, which has the advantage of reducing dust from escaping from the workshop's inlet and outlet.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] This utility model provides a closed structure for a cement bulk workshop, including a workshop and an inlet and an outlet set on the workshop. The inlet is provided with a first roller shutter door for closing the inlet, and the outlet is provided with a second roller shutter door for closing the outlet.

[0008] By adopting the above technical solution, when the vehicle approaches the workshop entrance, the first opening component automatically opens the first roller shutter door, and the vehicle enters the workshop from the entrance. Then, the first opening component automatically closes the first roller shutter door. After the cement bulk truck finishes loading, the vehicle in the workshop approaches the exit, and the second opening component automatically opens the second roller shutter door. Then, the vehicle drives out of the workshop from the exit, and the second opening component automatically closes the second roller shutter door. At this time, the first and second roller shutter doors can reduce dust from escaping from the workshop entrance and exit, thus reducing pollution of the surrounding environment. It is simple and convenient to use.
[0009] Preferably, the first opening component includes a placement groove on the ground, and a ground induction coil for controlling the opening or closing of the first roller shutter door is placed in the placement groove. Several prefabricated plates are horizontally arranged between the opposite side walls of the placement groove, and a prefabricated closing plate is placed on the top of each prefabricated plate. The prefabricated closing plate closes the opening of the placement groove. The second opening component has the same structure as the first opening component. At this time, the placement groove is set on the ground near the exit in the workshop.
[0010] Preferably, both the first and second roller shutters are PVC plastic roller shutters, and the central areas of both the first and second roller shutters are made of transparent PVC plastic.
[0011] Preferably, two opposing columns are provided on the ground outside the workshop near the entrance, and the two columns are located on both sides of the placement slot, with the distance between the two columns being less than the distance between the left and right sides of the entrance.
[0012] Preferably, both columns are fitted with rubber buffer rings.
[0013] Preferably, a distance sensor is provided at the top of each of the two columns, and an alarm light is provided at the end of the outer wall of the workshop near the entrance, with both distance sensors controlling the alarm light to operate.
[0014] The beneficial effects of this utility model are as follows: When in use, as the vehicle approaches the workshop entrance, the first opening component automatically opens the first roller shutter door, and then the vehicle enters the workshop from the entrance. Then, the first opening component automatically closes the first roller shutter door. After the cement bulk truck finishes loading, the vehicle in the workshop approaches the exit, and the second opening component automatically opens the second roller shutter door. Then, the vehicle drives out of the workshop from the exit, and then the second opening component automatically closes the second roller shutter door. At this time, the first and second roller shutter doors can reduce dust from escaping from the workshop entrance and exit, thus reducing pollution of the surrounding environment. It is simple and convenient to use. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] A closed structure for a cement bulk handling workshop, such as Figure 1 and Figure 2 The facility includes a workshop 1 and an inlet 2 and an outlet 3 located on the workshop 1. The inlet 2 is equipped with a first roller shutter door 4 for closing the inlet 2, and the outlet 3 is equipped with a second roller shutter door 5 for closing the outlet 3. The first roller shutter door 4 and the second roller shutter door 5 have the same structure. A first opening component for opening the first roller shutter door 4 is located on the ground outside the workshop 1 near the inlet 2, and a second opening component for opening the second roller shutter door 5 is located on the ground inside the workshop 1 near the outlet 3.
[0023] like Figure 1 and Figure 2When in use, when a vehicle approaches the entrance 2 of workshop 1, the first opening component automatically opens the first roller shutter door 4, and the vehicle enters workshop 1 from the entrance 2. Then, the first opening component automatically closes the first roller shutter door 4. After the cement bulk truck finishes loading, the vehicle in workshop 1 approaches the exit 3, and the second opening component automatically opens the second roller shutter door 5. Then, the vehicle drives out of workshop 1 from the exit 3, and the second opening component automatically closes the second roller shutter door 5. At this time, the first roller shutter door 4 and the second roller shutter door 5 can reduce the amount of dust that escapes from the entrance 2 and the exit 3 of workshop 1 and pollutes the surrounding environment. It is simple and convenient to use.
[0024] like Figure 1 and Figure 2 and Figure 3 The first opening component includes a placement groove 6 set on the ground, and a ground induction coil 7 for controlling the opening or closing of the first roller shutter door 4 is placed in the placement groove 6. Several prefabricated plates 8 are horizontally arranged between the opposite side walls of the placement groove 6, and a prefabricated closing plate 9 is placed on the top of each prefabricated plate 8. The prefabricated closing plate 9 closes the opening of the placement groove 6. The second opening component has the same structure as the first opening component. At this time, the placement groove 6 is set on the ground in the workshop 1 near the exit 3.
[0025] like Figure 1 and Figure 2 and Figure 3 As the vehicle approaches entrance 2, it is positioned above placement slot 6. When the inductive coil 7 in placement slot 6 detects a large metal object (car), it will control the first roller shutter door 4 to open. After the vehicle passes over placement slot 6 and enters workshop 1 from entrance 2, the inductive coil 7 will no longer detect a large metal object (car) and will control the first roller shutter door 4 to close. This achieves automatic opening or closing of the first roller shutter door 4. The second opening mechanism works on the same principle as the first opening mechanism.
[0026] The inductive coil 7 is an existing structure, and will not be described in detail here.
[0027] like Figure 1 Both the first roller shutter door 4 and the second roller shutter door 5 are PVC plastic roller shutter doors, and the middle area of the first roller shutter door 4 and the second roller shutter door 5 is transparent PVC plastic. The purpose of this setting is that, through the transparent middle area of the first roller shutter door 4 and the second roller shutter door 5, it is convenient for the vehicle driver to observe whether there are vehicles loading bulk cement in workshop 1.
[0028] like Figure 1Two opposing pillars 10 are installed on the ground near entrance 2 outside workshop 1, and the two pillars 10 are located on both sides of the placement slot 6. The distance between the two pillars 10 is smaller than the distance between the left and right sides of entrance 2. The purpose of this arrangement is to reduce the possibility of vehicles colliding with the side wall of entrance 2 when entering workshop 1 from entrance 2 due to improper vehicle alignment, thus preventing damage to entrance 2 of workshop 1.
[0029] like Figure 1 Both pillars 10 are fitted with rubber buffer rings 12. The purpose of this is to reduce the damage to the vehicle when it comes into contact with the pillars 10.
[0030] like Figure 1 and Figure 2 Distance sensors 13 are installed at the top of each of the two pillars 10. A warning light 14 is installed on the outer wall of the workshop 1 near the entrance 2. Both distance sensors 13 control the warning light 14 to work. The purpose of this setting is that when the front of the vehicle is aligned with the two pillars 10 and the vehicle body is tilted, the distance sensors 13 on the pillars 10 will detect the distance between the tilted vehicle body and the pillars 10. At this time, the distance sensors 13 will control the warning light 14 to work, reminding the driver that the vehicle is not straight and reducing the risk of the vehicle contacting and colliding with the pillars 10.
[0031] When the vehicle is aligned with the two pillars 10 and the vehicle is straight, the distance sensor 13 does not detect data, and the warning light 14 stops working. It is simple and convenient to use.
[0032] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
