Technical Field

[0001] This utility model belongs to the technical field of calcium carbide furnace silo closing valve, specifically relating to a sealing device for a calcium carbide furnace silo closing valve. Background Technology

[0002] A utility model patent with patent authorization announcement number CN220060507U discloses a sealing device for a calcium carbide furnace hopper, which includes a hopper, a shut-off valve, a front mounting half-ring, a rear mounting half-ring, a front sealing half-ring, a rear sealing half-ring, and a sealing box. The shut-off valve is provided at the lower part of the hopper. The front mounting half-ring is provided on the outer side of the front part of the shut-off valve, and the rear mounting half-ring is provided on the outer side of the rear part of the shut-off valve. The rear end of the front mounting half-ring and the front end of the rear mounting half-ring are detachably fixed together. The front sealing half-ring is fixedly installed on the inner side of the upper end of the front mounting ring, located above the shut-off valve.

[0003] During the long-term operation of calcium carbide furnace equipment in the calcium carbide industry, the original design of the silo feeding system has a shut-off valve installed at the bottom of the silo. During the operation of the calcium carbide furnace equipment, due to the continuous replacement and downward movement of raw materials, there are factors such as uneven feeding, pressure fluctuations in the furnace, and frequent changes in the material layer structure. When furnace gas is released, it will frequently overflow from the shut-off valve at the bottom of the silo, and powdery raw materials will be sprayed out. As a result, the carbon monoxide content and dust content in the space where the shut-off valve is located will seriously exceed the standard in a short period of time, which will not meet the safety operation requirements and seriously affect the occupational health of the operators. Summary of the Invention

[0004] The purpose of this utility model is to provide a sealing device for the closing valve of the feed hopper of a calcium carbide furnace. This device solves the problem that during the operation of the calcium carbide furnace, due to the continuous displacement and downward movement of raw materials, there are factors such as uneven feeding, pressure fluctuations inside the furnace, and frequent changes in the material layer structure. When furnace gas is released, it frequently overflows from the closing valve at the bottom of the feed hopper, and powdery raw materials are sprayed out. This causes the carbon monoxide and dust content in the space where the closing valve is located to seriously exceed the standards in a short period of time, making it impossible to meet the requirements for safe operation and seriously affecting the occupational health of the operators.

[0005] To achieve the above objectives, this utility model provides a sealing device for the closing valve of a calcium carbide furnace silo, comprising a closing valve one, a closing valve two contacting the right end of the closing valve one, mounting plates one fixedly connected to both the front and rear sides of the closing valve one, mounting plates two fixedly connected to both the front and rear sides of the closing valve two, the mounting plates two contacting the mounting plates one, the mounting plates two and the mounting plates one being provided with a common positioning mechanism, a rubber ring fixedly connected to the inner wall of the closing valve one, the rubber ring contacting the closing valve two, and a reinforcing rod fixedly connected to the inner wall of the rubber ring.

[0006] The principle of this utility model is as follows: by pushing the second closing valve to contact the first closing valve, the second mounting plate to contact the first mounting plate, and the positioning rod is forced through the mounting block. Under the pressure of the end of the positioning rod, the insertion rod can be pushed to move, so as to drive the connecting plate to slide along the surface of the guide plate, causing the spring to deform, and finally the insertion rod to contact the surface of the positioning rod. Under the action of force, the insertion rod can slide along the surface of the positioning rod. When the insertion rod slides into the insertion hole on the surface of the positioning rod, the spring returns to its deformation, so as to pull the positioning rod to insert the insertion rod, thereby positioning the first mounting plate and the second mounting plate, and then quickly positioning the second closing valve and the first closing valve for use, which facilitates the subsequent bolt fixing process.

[0007] The sealing ring, made of fiberglass wool, ensures a good sealing effect between the closing valve and the hopper. The rubber ring improves the contact sealing performance, and the reinforcing rod ensures good pressure resistance and durability. The friction groove also improves the assembly stability between the rubber ring and the closing valve.

[0008] The beneficial effects of this utility model are as follows: This solution, through the setting of springs, plug rods and other structures, allows for the insertion of the positioning rod, ensuring a stable connection between the first and second material closing valves, enabling rapid positioning between them. Combined with the functions of mounting plates one and two, it allows for locking between the first and second material closing valves and the hopper. The sealing ring, made of fiberglass cotton, ensures a good sealing effect for the material closing valves. The rubber ring improves the contact sealing performance, and the reinforcing rod ensures good pressure resistance and durability. Furthermore, the friction groove enhances the assembly stability of the rubber ring.

[0009] Furthermore, the surface of the first mounting plate is provided with a first mounting hole, and the surface of the second mounting plate is provided with a second mounting hole. Through the setting of the first mounting hole and the second mounting hole, bolts can be installed and used to lock the first and second closing valves.

[0010] Furthermore, a sealing ring is fixedly connected to the inner wall of the rubber ring. The sealing ring is made of glass fiber cotton. The sealing ring ensures a good sealing shape for the valve and the glass fiber cotton has good durability and sealing properties.

[0011] Furthermore, multiple reinforcing rods are provided, and the multiple reinforcing rods are arranged in a ring array on the rubber ring. By providing reinforcing rods, the structural strength of the rubber ring can be improved.

[0012] Furthermore, the inner wall of the second closing valve is provided with a plurality of friction grooves, which are evenly distributed on the second closing valve. The friction grooves can improve the friction effect on the surface of the second closing valve.

[0013] Furthermore, the positioning mechanism includes a mounting block. The lower end of the mounting plate one is fixedly connected to the mounting block, and the lower end of the mounting plate two is fixedly connected to a positioning rod. The positioning rod is slidably connected to the mounting plate one and to the mounting block. The lower end of the mounting block is fixedly connected to a guide plate, and a connecting plate is slidably sleeved on the outer side of the guide plate. A spring is provided on the outer side of the guide plate, and an insertion rod is fixedly connected to the upper end of the connecting plate. The insertion rod is slidably connected to the positioning rod. Through the cooperation of the insertion rod and the spring, the positioning rod can be inserted and limited, thereby positioning the material closing valve two and the material closing valve one.

[0014] Furthermore, one end of the spring is welded to the connecting plate, and the other end of the spring is welded to the mounting block. The connecting plate can be connected and used by means of the spring. Attached Figure Description
