DETAILED DESCRIPTION
[0016] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.
[0017] like Figure 1-4The fireproof mud extrusion molding equipment shown in the figure comprises a cylinder 1 for accommodating the fireproof mud and a pressure piston 2 for extrusion molding inside the cylinder 1, the pressure piston 2 moves inside the cylinder 1 to extrude the fireproof mud, a detachable rear end cover 3 is arranged at the rear end of the cylinder 1, a pressure pipe 4 is connected to the bottom of the cylinder 1 between the rear end cover 3 and the pressure piston 2, and the other end of the pressure pipe 4 is connected to an air pump 5, and the air pump 5 adjusts the air pressure inside the cylinder 1 through the pressure pipe 4 to push the pressure piston 2 to move;
[0018] A feed pipe 6 is installed on the top of the cylinder 1, the feed pipe 6 is connected to the inside of the cylinder 1, and a valve 7 for controlling the on-off of the feed pipe 6 is installed on the feed pipe 6;
[0019] The front end of the cylinder 1 is connected with a discharge pipe 8, and a pipe seat 9 is provided at the bottom of the discharge pipe 8. The pipe seat 9 is sleeved on the outside of the front end of the cylinder 1;
[0020] Based on the above, when working, open the material valve 7 to make the feed pipe 6 unobstructed, and put the raw materials to be processed and formed into the cylinder 1 from the feed pipe 6, and then the air pump 5 works. The working pressure pipe 4 of the air pump 5 adjusts the air pressure inside the cylinder 1, pushes the pressure piston 2 to move inside the cylinder 1, squeezes and pushes the raw materials in the cylinder 1, and completes the extrusion molding from the discharge pipe 8 at the front end of the cylinder 1.
[0021] Furthermore, a heat pipe for heating the cylinder 1 is embedded in the cylinder wall of the cylinder 1. By heating the cylinder 1, the internal temperature of the cylinder 1 is increased, so that the fireproof mud raw material is heated and softened inside the cylinder 1, which is convenient for extrusion molding.
[0022] An equipment platform 10 is provided at the bottom of the cylinder 1, the air pump 5 is installed on the equipment platform 10 and is located at the bottom of the cylinder 1, a support frame 11 and a support seat 12 are installed on the equipment platform 10, the pipe seat 9 is installed on the top of the support frame 11, and the rear end of the cylinder 1 is fixed on the top of the support seat 12;
[0023] The support seat 12 and the support frame 11 support the entire cylinder 1 part. The discharge pipe 8 at the front end of the cylinder 1 is used for discharging, and the rear cover 3 at the rear end is detachable, which is convenient for the maintenance and replacement of the interior of the cylinder 1 and the pressure piston 2. The fireproof mud extrusion molding is realized by pushing the pressure piston 2 by utilizing the pressure change in the inner cavity of the cylinder 1, so that the overall volume of the entire extrusion molding equipment is reduced, the weight of the equipment is reduced, and it is convenient to carry and use. At the same time, the extrusion molding can be completed without long-distance spiral mixing, which improves the efficiency of fireproof mud mixing molding.
[0024] The end of the rear end cover 3 is inserted into the interior of the rear end of the cylinder 1, and a sealing ring 13 is provided between the rear end cover 3 and the rear end surface of the cylinder 1;
[0025] The rear end cover 3 is inserted into the interior of the rear end of the cylinder 1 by means of threads. The rear end cover 3 is installed and removed by twisting and rotating. The sealing ring 13 improves the sealing between the rear end cover 3 and the cylinder 1.
[0026] The pressure piston 2 includes a metal inner liner 14 and a rubber sleeve 15 sleeved on the outside of the metal inner liner 14, the rubber sleeve 15 is in contact with the inner wall of the cylinder 1, a through hole 16 is provided on the side of the rubber sleeve 15 close to the rear end cover 3, an end seat 17 protruding outward and located in the through hole 16 is provided on the outer wall of the metal inner liner 14, and a screw hole 18 is provided on the end seat 17.
[0027] Based on the above, when the raw material is injected, the material valve 7 is in an open state, and the pressure piston 2 is located in the cylinder 1 between the connection between the pressure tube 4 and the cylinder 1 and the connection between the feed tube 6 and the cylinder 1. When the pressure piston 2 is located here, the raw material entering the cylinder 1 can be located on the other side of the pressure piston 2, and will not cause blockage to the pressure tube 4. When the air pump 5 works to convey gas to the cylinder 1 through the pressure tube 4 for pressurization, the air pressure is conveyed to the area between the pressure piston 2 and the rear end cover 3. When the air pressure therein increases, the pressure piston 2 will be pushed to move to the other end of the cylinder 1, and the raw material in the cylinder 1 will be extruded and formed from the discharge pipe 8 at the front end of the cylinder 1.
[0028] Among them, the air pump 5 is a dual-purpose air pump 5 for blowing and sucking. After the raw material is extruded and formed, the air pump 5 can suck air to reduce the air pressure on one side of the pressure piston 2, drive the pressure piston 2 to reset, and carry out the next round of molding operation.
[0029] Furthermore, the pressure piston 2 is composed of an outer rubber sleeve 15 and an inner metal liner 14. After the rear end cover 3 is removed, the pressure piston 2 can be inserted into the screw hole 18 on the end seat 17 at the rear end of the cylinder 1 by a screw or other tool, and then the pressure piston 2 is pulled out to the outside of the cylinder 1 by force, and the pressure piston 2 is taken out of the cylinder 1 for cleaning or replacement, and then the inside of the cylinder 1 is cleaned to avoid blockage at the pressure pipe 4;
[0030] After cleaning, the pressure piston 2 is reinserted into the cylinder 1, and the pressure piston 2 is pushed into the cylinder 1 until the connection between the pressure tube 4 and the cylinder 1 is exposed, so that the pressure tube 4 is unobstructed. At this time, the other side of the pressure piston 2 is located at the edge of the feed pipe 6 and will not cause blockage to the feed pipe 6.
[0031] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
