[0020] The present invention is described in detail below by way of exemplary embodiments. However, it should be understood that, without further description, elements, structures and features in one embodiment may also be beneficially combined in other embodiments.

[0021] It should be noted that: unless otherwise defined, the technical terms or scientific terms used in this document shall have the usual meanings understood by people with ordinary skills in the field to which the invention belongs. The words "one", "an" or "the" and the like used in the patent application specification and claims of the present invention do not express quantity restrictions, but indicate the existence of at least one; the words "first", "second" and "third" used in this document shall not be regarded as restrictions on the order of components, but are only used to distinguish different components; words such as "include" or "comprise" and the like indicate that the elements or objects appearing before "include" or "comprise" include the elements or objects listed after "include" or "comprise" and their equivalents, but do not exclude other elements or objects with the same function.

[0022] In order to more clearly describe the specific structural composition of the fixed gyratory crushing station silo sealing door device, combined with the attached Figure 1-2 Describe this embodiment: like Figure 1 , Figure 2 As shown, a fixed gyratory crushing station silo sealing door device, the silo 1 has a door opening, and two maintenance slide rails 2 connecting the inner and outer sides of the silo 1 are arranged on the top inner side of the door opening. The sealing door device includes two main door panels 3 and a lifting sliding door 4 and a transverse sliding door group correspondingly arranged on each main door panel 3, which divides the door opening into multiple parts. Each part is closed by the main door panel 3, the lifting sliding door 4 and the transverse sliding door (the first transverse sliding door 5 or the second transverse sliding door 6), thereby realizing the gapless closure of the entire door opening. The main structures of the sealing door device are described below: The main door panel 3 is hinged to the two sides of the door opening through the door axis mechanism 301. The two main door panels 3 are respectively located under the corresponding maintenance slide rails 2, and after rotation, the part of the door opening under the maintenance slide rail 2 is closed; the door axis mechanism is used to connect the main door panel 3 and the door opening, and can make the main door panel 3 rotate around the door axis mechanism to realize the opening and closing of the two main door panels.

[0023] The lifting sliding door 4 is slidably arranged at the upper end of each main door panel 3. Each main door panel 3 is also provided with an adjustment mechanism for driving the lifting sliding door 4 to move up and down. The lifting sliding door 4 is correspondingly located between the two maintenance slide rails 2; the function of the lifting sliding door 4 is to close the door opening between the two maintenance slide rails 2 after rising.

[0024] The transverse sliding door group includes a first transverse sliding door 5 that is transversely slidably arranged on the lifting sliding door 4 and a second transverse sliding door 6 that is transversely slidably arranged at the top of both sides of the door opening; the first transverse sliding door 5 and the second transverse sliding door 6 are used to close the door openings on both sides of the maintenance slide rail 2, and are attached to the sides of the maintenance slide rail 2 to achieve full closure of the door opening. After the two main door panels 3 are closed and the two lifting sliding doors 4 move up to contact the top of the door opening, the first transverse sliding door 5 and the second transverse sliding door 6 can move from both sides of the corresponding maintenance slide rail 2 toward the maintenance slide rail 2, and abut against both sides of the corresponding maintenance slide rail 2, and cooperate with the main door panel 3 and the lifting sliding door 4 to close the entire door opening without gaps.

[0025] In the above embodiment, the maintenance slide rail 2 is arranged at a height between the upper end and the lower end of the second transverse sliding door 6. The end of the first transverse sliding door 5 or the second transverse sliding door 6 facing the maintenance slide rail 2 has a groove that matches the cross section of the maintenance slide rail 2. When the maintenance slide rail 2 is an I-beam as shown in the figure, the groove on each transverse sliding door is half of the cross-sectional shape of the I-beam, and the grooves of the two transverse sliding doors form a complete cross-sectional shape. After the two transverse sliding doors on the upper side of the same main door panel 3 are connected, the maintenance slide rail 2 is in the complete groove without a gap.

[0026] In the above embodiment, the vertical height of the lifting sliding door 4, the first transverse sliding door 5 and the second transverse sliding door 6 is greater than the distance from the top of the main door panel 3 to the top of the door opening, ensuring that the three can cooperate to completely close the door opening gap on the upper side of the main door panel 3.

[0027] In the above embodiment, locking mechanisms (14, 15, 16, 17) are provided on the main door panels and the sliding doors to realize the connection between adjacent panels (door panels or sliding doors) so as to ensure the overall stability. The main door panel 3 is clamped with another main door panel 3 or the bottom of the door opening through the locking mechanism; the lifting sliding door 4, the first transverse sliding door 5 and the second transverse sliding door 6 are clamped with the top of the door opening through the locking mechanism. The locking mechanism can be a latch structure, a buckle structure, etc., which is roughly divided into a parent body and a child body, and the two parts are respectively fixed on adjacent matching panels.

[0028] In the above embodiment, the adjustment mechanism specifically includes a fixed seat 7 fixed on the main door panel 3 and a movable seat 8 fixed on the lifting sliding door 4; the threaded hole of the fixed seat 7 is threaded with a vertical screw rod 9, the top of the screw rod 9 is rotatably connected to the movable seat 8, and the bottom of the screw rod 9 is fixed with a handle 10. The screw rod 9 is driven to rotate by the handle 10, so that the lifting sliding door 4 is lifted and lowered against the main door panel 3.

[0029] Handles 11 are provided on the outer surfaces of the first transverse sliding door 5 and the second transverse sliding door 6 to facilitate transverse pushing and pulling.

[0030] In the above example, in order to improve the overall sealing, sealing rings 12 can be provided on the edges of the main door panel 3, the lifting sliding door 4, the first transverse sliding door 5 and the second transverse sliding door 6. In the closed state, the sealing rings fill the gap between the adjacent parts of each plate body and the side walls of the plate body and the door opening.

[0031] In the above embodiment, in order to ensure the stable movement of the lifting sliding door 4, the first transverse sliding door 5, and the second transverse sliding door 6, door rails corresponding to each sliding door can be set, such as two horizontal door rails 13 fixed at the top of both sides of the door opening, and the slider of the second transverse sliding door 6 is in the sliding groove of the door rail 13.

[0032] After the silo maintenance is completed, the sealing door device needs to be in a fully closed state to achieve a good sealing effect. The closing sequence and process are as follows: First, the main door panel 3 on the left is rotated and closed, and then the main door panel 3 is initially tightened by the locking mechanism installed on the main door panel and the door opening; then the lifting and sliding door 4 on the left is moved upward along the door track embedded in the main door panel 3 on the left through the adjustment mechanism until it reaches the specified position and is tightened by the locking mechanism on the lifting and sliding door 4 and the door opening; then the first transverse sliding door 5 on the left is pushed to move to the left along the door track embedded in the lifting and sliding door 4 on the left until there is no gap between the track and the locking mechanism; then the second transverse sliding door 6 on the left is pushed to move to the right along the door track 13 embedded on the upper side of the door opening until there is no gap between the maintenance slide rail 2 and the locking mechanism; finally, the main door panel 3, lifting and sliding door 4, first transverse sliding door 5 and second transverse sliding door 6 on the right are closed and closed according to the same steps. When the doors on both sides are closed, the left and right main door panels 3 and the left and right lifting and sliding doors 4 can be further tightened by the locking mechanism.

[0033] The parts not described in detail in the above embodiments are prior art.

[0034] It should be noted that although the present invention is described by the above embodiments, the present invention may also have other various embodiments. Without departing from the spirit and scope of the present invention, it is obvious that those skilled in the art may make various corresponding changes and deformations to the present invention, but these changes and deformations should all fall within the scope of protection of the appended claims of the present invention and their equivalents.
