The utility model relates to the technical field of chemical materials, and discloses an environment-friendly storage and transportation device for phenolic plastic production, which comprises a storage cylinder, the outer surface of the storage cylinder is fixedly connected with a flange plate, and the upper surface of the storage cylinder is fixedly provided with a closed top cover through the flange plate. The tight sealing performance between the sealing top cover and the storage barrel is ensured, harmful gas leakage is effectively prevented, the arrangement of the protection steel rods and the inclined supporting rods can effectively resist external impact and pressure in the transportation or storage process, the problem that the barrel body is damaged, and consequently the harmful gas in the storage barrel leaks and overflows is solved, and the service life of the storage barrel is prolonged. And meanwhile, an activated carbon filter screen and a negative ion filter screen are arranged in the cylinder body, the negative ion filter screen can release negative ions, the air quality of the storage environment is improved, harmful gas in the storage cylinder can be effectively removed through double filtration, and the situation that when a person opens the closed cover body, the internal harmful gas is accumulated, and the body of the person is affected is avoided.

The utility model relates to the technical field of phenolic plastic production, and discloses a phenolic plastic production mixing tank sealing structure which comprises a storage mechanism, a tank body mechanism and a top end mechanism, the tank body mechanism is arranged at the left end of the storage mechanism, the top end mechanism is arranged at the top end of the tank body mechanism, and the storage mechanism comprises a supporting plate. A sliding groove is formed in the top end of the supporting plate. According to the device, a connecting ring is arranged to be matched with a first valve rotating inside, so that the device can be taken down through threaded rotation on the surface of a conveying pipe, then a storage box is matched with the interiors of a sliding groove and a supporting plate to be taken out in a sliding mode, and workers can conveniently treat harmful gas stored in the storage box; by arranging the second valve, combustible steam in the production process can be blocked into the mixing tank body, and then the combustible steam in the storage box is blocked by rotating the first valve, so that the combustible steam is prevented from overflowing, combustible and toxic gas in the environment is prevented from being gathered, and accidents such as fire disasters, explosions and personnel poisoning are avoided.

The invention discloses production equipment for phenolic plastic preparation and a method thereof, and belongs to the field of chemical manufacturing, a deceleration torsion assembly is further arranged on the side wall of a supporting stand column, a heating mechanism is arranged below a reaction kettle, a material fishing assembly is arranged at the bottom end of an objective table, and a lifting assembly is arranged at the top end of the objective table; linear propelling mechanisms are arranged at the two ends of the hoisting guide rail, and a kneading treatment assembly is arranged on one side of the base table plate. A formaldehyde removing solution and a hydrochloric acid solution are poured into the inner side of the reaction kettle, a metal heat conduction plate can be heated after alternating current is supplied, the metal heat conduction plate heats a solid-liquid mixture in the reaction kettle to start chemical reaction, and after the chemical reaction is completed, a lifting motor drives a lifting rack to fall down through a lifting gear; and then the stepping motor drives the carrying belt to operate through the carrying roller, and the objective table slides out along the hoisting guide rail opposite to the carrying belt for unloading, so that the effect of automatic unloading is realized.

The utility model relates to a phenolic plastic stirring device with an automatic feeding function, which comprises a reaction kettle, a stirring cavity is formed in the reaction kettle, and a stirring mechanism is mounted in the stirring cavity; a discharging pipe communicated with the stirring cavity is fixedly arranged on the lower side of the reaction kettle; a feeding pipe communicated with the stirring cavity is fixedly arranged on the upper side of the reaction kettle, and a control assembly is arranged in the feeding pipe; a premixing mechanism is arranged on the upper side of the feeding pipe, a rotating air cylinder drives a rotating shaft to rotate, so that a control plate can swing front and back, a gap can be formed between the outer edge of the control plate and the inner wall of the feeding pipe along with swinging of the control plate, and the size of the gap changes along with the inclination angle of the control plate; therefore, the feeding speed of the raw materials is controlled by controlling the size of the gap, so that the raw materials in the reaction kettle can react to generate required products, and the product quality is ensured.

The application provides a kind of high-performance mechanical seal graphite filled phenolic plastic and its preparation method, the plastic includes the following components by weight parts: phenolic resin 50-80 parts, graphite 20-35 parts, petroleum coke 10-15 parts, compound lubricant 5-15 parts, coupling agent 1-3 parts, curing agent 8-15 parts, curing accelerator 1-3 parts, toughening agent 10-20 parts, calcium metasilicate 2-7 parts and ethylene bis-stearamide 1-3 parts.The application uses compound lubricant composed of zinc stearate, calcium laurate and ethylene bis-stearamide, which cooperates with graphite to form continuous and stable lubricating film on the friction interface.Zinc stearate and calcium laurate provide initial and medium temperature lubrication, and ethylene bis-stearamide migrates to the surface at high temperature to make up the defect of high temperature failure of single graphite lubricating film.Meanwhile, petroleum coke supports the lubricating layer as rigid skeleton to avoid the lubricant being squeezed out too fast.
