Description

Technical Field

[0001] This utility model relates to the technical field of powder grinding equipment, specifically to an integrated grinding and screening equipment for refractory materials in a pyrolysis furnace. Background Technology

[0002] A cracking furnace is an important piece of equipment in the petrochemical industry, which converts heavy petroleum into light petroleum products through high-temperature cracking. During the operation of the cracking furnace, refractory materials play a crucial role; they not only withstand high temperatures and chemical corrosion but also maintain the structural integrity and stability of the furnace body.

[0003] Refractory castable is a commonly used refractory material for preparing pyrolysis furnace linings. It is a mixture of refractory aggregates, powders, and binders. After adding water or other liquids, it is suitable for construction using pouring or vibration methods. It can also be prefabricated into precast components of specified shapes and dimensions for constructing industrial furnace linings. It is a widely used and widely applicable monolithic refractory material in furnace construction engineering. Refractory castable is a powdered raw material that is mixed with water to form a castable refractory slurry for use.

[0004] When preparing refractory materials, the raw materials need to be ground into components. Different refractory materials have different requirements for the particle size of the powder. Therefore, in the grinding of refractory materials, it is not only necessary to grind the raw materials into powder, but also to sieve the powder. Existing integrated grinding and sieving equipment has high energy consumption and low sieving efficiency. Therefore, an integrated grinding and sieving equipment for pyrolysis furnace refractory materials is needed. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an integrated equipment for grinding and screening refractory materials in a pyrolysis furnace.

[0006] The technical solution of this utility model is: an integrated grinding and screening device for refractory materials in a pyrolysis furnace, comprising a grinding chamber, a feeding port at the top of the grinding chamber, a boss at the center of the bottom of the grinding chamber, an air intake mechanism on the boss, a grinding motor at the bottom of the grinding chamber, a connecting rod connected to the output shaft of the grinding motor, the top of the connecting rod passing through the boss and rotatably connected to the boss, a crossbar fixedly connected to the top of the connecting rod, a grinding wheel rotatably connected to each end of the crossbar, and a discharge device fixedly connected to the left side of the grinding chamber.

[0007] Furthermore, the air intake mechanism includes multiple air intake pipes, which are fixedly connected within the boss. The lower top of the air intake pipe is connected to the lower part of the grinding chamber, and the top of the air intake pipe is fixedly connected to the interior of the grinding chamber. A bend is fixedly connected to the top of the air intake pipe.

[0008] Note: Air from the bottom of the grinding chamber is introduced into the grinding chamber through the air inlet pipe. The curved pipe prevents the raw material from falling into the air inlet pipe after feeding from above.

[0009] Furthermore, the discharge device includes an exhaust fan, the air inlet of which is fixedly connected to a suction pipe, the right end of which is closed, and two feed inlets fixedly connected to the lower part of which are connected to the lower part of the suction pipe. The air outlet of the exhaust fan is fixedly connected to a discharge pipe, and a filter bag is fixedly connected to the lower end of the discharge pipe.

[0010] Explanation: After the airflow exits from the bend, the fine dust particles, due to their low gravity, are lifted by the rising airflow and enter the feed inlet. Under the action of the exhaust fan, they are discharged from the discharge pipe and filtered by the filter bag, where the dust particles are trapped.

[0011] Furthermore, a support base is fixedly connected to the bottom of the grinding chamber.

[0012] Note: The support base can raise the grinding chamber, thereby providing unobstructed airflow to the intake pipe.

[0013] Furthermore, the feeding port of the grinding chamber is hinged with a sealing cover.

[0014] Note: The sealing cover can prevent airflow from entering the grinding chamber from the feed port, which can improve the working efficiency of the exhaust fan.

[0015] The beneficial effects of this utility model are:

[0016] This invention grinds refractory material into dust using a grinding wheel, and then lifts the powder into the air inlet pipe through an airflow blown out by a curved pipe, thereby completing the sieving of the ground powder. This invention has high grinding efficiency, good sieving effect, and a short path for the airflow to lift the dust, thus being more energy-efficient. This invention also has a simple structure, low manufacturing cost, and is easy to maintain. Attached Figure Description

Detailed Implementation

[0021] Example 1:

[0022] like Figure 1 As shown, a pyrolysis furnace refractory material grinding and screening integrated equipment includes a grinding chamber 1, a feeding port 2 at the top of the grinding chamber 1, a boss 3 at the center of the bottom of the grinding chamber 1, an air intake mechanism 4 on the boss 3, a grinding motor 5 at the bottom of the grinding chamber 1, a connecting rod 6 connected to the output shaft of the grinding motor 5, the top of the connecting rod 6 passing through the boss 3 and rotatably connected to the boss 3, a crossbar 7 fixedly connected to the top of the connecting rod 6, a grinding wheel 8 rotatably connected to each end of the crossbar 7, and a discharge device 9 fixedly connected to the left side of the grinding chamber 1.

[0023] The air intake mechanism 4 includes multiple air intake pipes 41. The air intake pipes 41 are fixedly connected inside the boss 3. The top and lower end of the air intake pipes 41 are connected to the bottom of the grinding chamber 1. The top of the air intake pipes 41 are fixedly connected to the inside of the grinding chamber 1. A bend 42 is fixedly connected to the top of the air intake pipes 41.

[0024] Air is introduced into the grinding chamber 1 from the bottom through the air inlet pipe 41. The bend pipe 42 prevents the raw material from falling into the air inlet pipe 41 after the material is added from above.

[0025] The discharge device 9 includes a blower 91, the air inlet of the blower 91 is fixedly connected to a suction pipe 92, the right end of the suction pipe 92 is closed, the lower part of the suction pipe 92 is fixedly connected to two feed inlets 93, the air outlet of the blower 91 is fixedly connected to a discharge pipe 94, and the lower end of the discharge pipe 94 is fixedly connected to a filter bag 95.

[0026] After the airflow is discharged from the bend 42, the fine dust particles are lifted by the rising airflow due to their low gravity and enter the feed inlet. Under the action of the exhaust fan 91, they are discharged from the discharge pipe 94 and filtered by the filter bag 95, where the dust particles are trapped.

[0027] A support base 11 is fixedly connected to the bottom of the grinding chamber 1.

[0028] The support base 11 can lift the grinding chamber 1, thereby providing unobstructed airflow to the air intake pipe 41.

[0029] Example 2:

[0030] Based on Example 1, Example 2 differs from Example 1 in that the feeding port 2 of the grinding chamber 1 is hinged with a sealing cover plate 21.

[0031] The sealing cover 21 added in Example 2 can prevent airflow from entering the grinding chamber 1 from the feed port 2, thereby improving the working efficiency of the exhaust fan 91. Therefore, Example 2 is better than Example 1.

[0032] The working method of the above embodiment 2 includes the following steps:

[0033] S1. Add the raw material to be ground into the grinding chamber 1 through the feeding port 2, start the grinding motor 5 and the exhaust fan 91. The grinding motor 5 drives the connecting rod 6 to rotate, which in turn drives the crossbar 7 to rotate. The rotation of the crossbar 7 drives the grinding wheel 8 to rotate in the grinding chamber 1, and the grinding wheel 8 grinds the raw material.

[0034] S2. Air enters from the air inlet pipe 41 into the bend pipe 42, and then is discharged from the bend pipe 42 into the grinding chamber 1. The airflow in the grinding chamber 1 carries the ground powder into the suction pipe 92 from the feed inlet 93, and then is discharged from the discharge pipe 94 through the exhaust fan 91. The air is discharged from the filter bag 95, and the powder is trapped in the filter bag 95.

[0035] In the above embodiments, the grinding motor 5 and the exhaust fan 91 are both commercially available products. As long as they can achieve the function of this utility model, they are acceptable. Those skilled in the art can choose to use them based on common sense, and no special limitations are made here.
