Description

a lawn washing machine

technical field

The utility model belongs to the technical field of papermaking equipment, in particular to a grass washing machine.

Background technique

At present, papermaking is mainly divided into wood pulp papermaking and straw pulp papermaking. Wood pulp papermaking has a long history and mature technology. Because wood pulp papermaking uses forest trees as raw materials, and the forest coverage rate in China is low, the cost of wood pulp papermaking is relatively high. And have a certain impact on the environment. With the advancement of papermaking technology, straw pulp papermaking technology has been greatly developed. Using wool grass, cotton stalks, reeds, corn stalks, straw and other grasses as pulping raw materials does not need to consume forest resources. As a big agricultural country, our country is rich in crop stalks. Some of these crop stalks are crushed and returned to the field, some are discarded and wasteful, and many are incinerated, which wastes resources and pollutes the environment. Therefore, the development of straw pulp papermaking can not only achieve full resources Utilize, avoid waste, and can protect environment, have important social significance and economic benefit.

In the long-term practice in this field, the inventor has determined a new straw pulp papermaking process through a large number of repeated experiments, which saves the cooking steps and combines the stages of grinding and bleaching into one, which simplifies the process and realizes fast Soften at low temperature, the COD and chroma of the produced wastewater are greatly reduced, the pollution load is greatly reduced, and all the wastewater can be reused.

In the new process, in order to facilitate the pulping of raw materials in the paper industry, especially the pulping of raw materials, the above-mentioned raw materials need to be crushed before production, and then the crushed raw materials are cleaned, softened, kept warm, kneaded, reacted, and ground. , pulping, pulp washing, dehydration, pulp storage and other steps, especially the cleaning of raw materials is to remove impurities such as sediment and dust in the crushed papermaking materials, which directly affects the progress of subsequent links and the quality of pulp, and has an important role in the entire papermaking process. It plays a very important role, and it is particularly critical to choose a washing device suitable for raw material cleaning.

Most of the washing devices currently in use are equipped with a water tank with a feed inlet and a discharge outlet. The papermaking raw materials that have been treated to a certain extent enter the water tank through the feed inlet and then are discharged from the discharge outlet. The mud mixed in the papermaking raw materials Impurities such as sand and dust settle to the bottom of the water tank due to their higher specific gravity than water. There is a sewage pipe at the bottom of the water tank, and a filter is installed at the bottom of the water tank. When the switch of the sewage pipe is turned on, impurities such as sand and dust are filtered through The net is discharged with the sewage. For wood pulp and papermaking, because the raw materials of wood pulp and papermaking are first processed into small wood chips, small wood chips are generally the size of a matchbox, 3-5mm thick, contain less impurities, and the effect of cleaning and removing impurities is very good. But for straw pulp papermaking, because the raw materials of straw pulp papermaking are loose and messy, large in size, floating in water, containing more impurities such as silt and dust, it is easy to fill up the space in the water tank of the grass washing machine, making the washing space more difficult. Small, the effect of cleaning and removing impurities cannot meet the production requirements, and it is easy to cause blockage of the weed washing machine, which seriously affects the smooth progress of production.

Therefore, for the straw pulp papermaking process developed by the inventor, it is necessary to design a specific washing device to meet the requirements of the process.

Since the circumferential surface of the rotating roller is provided with several grooves in the circumferential direction, and shift forks are arranged in the grooves spaced apart from each other, and the shift forks in the grooves spaced apart from each other are arranged in a staggered manner, the adjacent shift forks in the same groove are relatively rotating The axially symmetrical arrangement of the rollers is beneficial to stirring and conveying the materials, and at the same time prevents the materials from being entangled on the shift fork as much as possible.

Because the water spray pipe extends through the tank wall of the water tank, the extension direction of the water spray pipe intersects with the discharge direction of the discharge port at an acute angle, and the sprayed water flow impacts the material, which is more conducive to the discharge of the material.

Since the top of the water tank above the rotating roller and the top of the discharge port are equipped with inspection ports, it is very easy to operate when the water tank is blocked or there is a problem that needs troubleshooting or maintenance, and the cover is closed on the inspection port, which can be opened and closed. Very convenient.

Since the bottom of the tank is tapered to form a conical tank bottom, it prevents impurities from depositing on the tank wall, making it easy for impurities to settle to the bottom of the tank. When the sewage pipe discharges sewage, the impurities are discharged together with the sewage. The bottom of the conical tank bottom can be disassembled and installed There is a disassembly part, and a filter element is installed between the disassembly part and the bottom of the conical groove. When the filter element is blocked or needs to be repaired and replaced, the disassembly part can be removed to repair or replace the filter element. The operation is simple, safe and fast.

Since the bottom end of the conical groove bottom and the top end of the disassembly part are respectively connected with a flange, and the two flanges correspond to each other and are connected by bolts, the structure is simple, the connection is firm and the disassembly is convenient. There is a mounting groove on the top, the mounting groove is larger than the inner diameter of the flange, and the filter element is installed in the mounting groove, so that the filter element is firmly installed and easy to disassemble.

Since the bottom end of the conical groove bottom and the top end of the disassembly part are provided with fixed edges extending along the circumference, the two fixed edges correspond in size and are connected by bolts, which can adapt to different diameters of the conical groove bottom, and the connection is firm And it is easy to disassemble and assemble.
