Description

Technical Field

[0001] The utility model belongs to the technical field of straw processing, and in particular relates to a crop straw fiber molding system. Background Art

[0002] At present, the annual output of straw is increasing year by year. Among the recyclable straw resources, about 15.0% is directly returned to the fields, about 30.7% is used to produce animal feed, about 17.9% is used for industrial energy, and only 5.25% is used in other project fields such as material preparation. The proportion of straw resources directly discarded and burned is as high as 31.6%, resulting in a lot of waste.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] Reference Figure 1-Figure 3A crop straw fiber molding system 10 (hereinafter referred to as the molding system 10) is mainly composed of a mixing system 100 and a molding system 200, wherein the mixing system 100 is a front system of the molding system 200, for adjusting parameters such as concentration, beating degree and wet weight of a mixed fiber raw material (to be described later) to output a mixed fiber material that meets the requirements to the molding system 200, and the mixed fiber material is further processed by the molding system 200 to obtain a fiber finished product.

[0041] In some embodiments, the mixing system 100 has a first crushing section, a first impurity removal section, a first abrasive section and a dosing section, which are fluidly connected in sequence. The mixed fiber raw material is processed by the first crushing section to become an intermediate circulation fiber material, which is processed by the first impurity removal section, the first abrasive section and the dosing section in sequence to become a mixed fiber material and then supplied to the molding system 200.

[0042] In some embodiments, the first crushing section is configured to crush the mixed fiber raw material and mix it with a certain amount of water to form an intermediate circulating fiber material of a set concentration. In some examples, the first crushing section is configured as a hydraulic fiber crusher, and the mixed fiber raw material is composed of crop straw fibers and auxiliary fibers in a set proportion. In some instances, taking the weight ratio as an example, crop straw fiber: auxiliary fiber = (60%~100%): (0~40%), and the auxiliary fibers are composed of bamboo fibers and bagasse fibers. In some embodiments, the concentration of the intermediate circulating fiber material output by the first crushing section is 4%~6%.

[0043] In some embodiments, the first impurity removal section is configured to remove impurities from the intermediate circulating fiber material from the first crushing section, and output the intermediate circulating fiber material after impurity removal to the first abrasive section. In some embodiments, the first impurity removal section is configured as a high-frequency desander, which has two functions of removing slag (referring to heavy impurities in the slurry) and desandering fiber. The heavy impurities in the intermediate circulating fiber material are removed by the centrifugal force generated by the difference in specific gravity between sand and fiber during high-speed rotation.

[0044] In some embodiments, the first abrasive part is configured as a double-disc grinding machine.

[0045] In some embodiments, the above-mentioned batching section is constructed as a mixing container (such as a tank), and the external additive and the intermediate flow fiber material output by the first abrasive section are fully mixed in the batching section, and after the concentration is adjusted by water, the mixed fiber material of the set concentration is output to the molding system 200. In some examples, the above-mentioned additives include one or more of waterproofing agents, oil-proof agents, dry strength agents, and Shunbang SNK-3 composite additives. In some examples, the concentration of the mixed fiber material is 0.3%.

[0046] In some embodiments, the mixing system 100 further includes a first tank body portion and a second tank body portion, wherein the first tank body portion is configured as a transfer tank body between the first crushing portion and the first impurity removal portion, that is, the first tank body portion is fluidically connected to the first crushing portion and the first impurity removal portion, respectively, and the intermediate flow fiber material output from the first crushing portion is transferred via the first tank body portion and then transported to the first impurity removal portion for impurity removal treatment. Correspondingly, the second tank body portion is configured as a transfer tank body between the first abrasive portion and the batching portion, that is, the second tank body portion is fluidically connected to the first impurity removal portion and the batching portion, respectively, and the intermediate fiber material output from the first abrasive portion is transferred via the second tank body portion and then supplied to the batching portion. In this example, the concentration adjustment process of the intermediate flow fiber material can be carried out in the second tank body portion, that is, only the auxiliary agent addition operation needs to be performed in the subsequent batching portion.

In this example, the shaping part is configured to drain and exhaust the molding wet embryo under high temperature and high pressure conditions so as to dry and shape the molding wet embryo to obtain a molding dry embryo. Specifically, during the operation of the molding system 200, the molding die takes out the molding wet embryo from the fiber scooping pool, and the moisture content of the molding wet embryo is reduced after being extruded by the extrusion die at the top, and the molding wet embryo is transferred to the shaping die in the mold. After draining and exhausting the moisture under high temperature and high pressure to obtain the molding dry embryo, the mold is opened and transferred out for automatic demolding.

[0049] In some embodiments, the molding section further comprises a reflux box, in which the discharged water during the forming process of the molded wet embryo and the working process of the extrusion die is gathered and flows back into the fiber scooping pool.

[0050] In some embodiments, the molding system 10 further comprises a vacuum system and a water recovery system, wherein the vacuum system is connected to the molding part and the shaping part in the molding system 200, and correspondingly, the water recovery system comprises a recovery tank body fluidly connected to the vacuum system, and the recovery tank body is fluidly connected to the first abrasive part, the first tank body part, the second tank body part and the batching part.
