Description

Technical Field

[0001] The invention relates to the technical field of biofuel raw material processing, and in particular to multifunctional biofuel raw material processing equipment. Background Art

[0002] Straw is the general name for the stems and leaves (ears) of mature crops. It is a renewable biological resource with multiple uses, such as biofuel. Biofuel refers to solid, liquid or gaseous fuels composed of or extracted from biomass. It can replace gasoline and diesel made from petroleum and is an important direction for the development and utilization of renewable energy. The so-called biomass refers to various organisms produced by photosynthesis using the atmosphere, water, land, etc., that is, all living organic matter that can grow, including plants, animals and microorganisms. Unlike traditional fuels such as oil, coal, and nuclear energy, these emerging fuels are renewable fuels.

[0003] During the processing of biofuel, the straw as raw material needs to be crushed by a crusher, and then the crushed raw material is transported to a dehydrator for dehydration. This requires multiple equipment to handle the process, which is cumbersome to operate, reduces work efficiency, and increases processing costs.

Summary of the invention

[0005] In view of the above technical problems, the purpose of the present invention is to overcome the problem in the prior art that straw as raw material needs to be crushed by a crusher, and then the crushed raw material needs to be transported to a dehydrator for dehydration, so that multiple equipment is needed for processing during the processing, the operation is cumbersome, the work efficiency is reduced, and the processing cost is increased.

In the crushing process, the raw material is prevented from being entangled in the crushing mechanism and affecting the normal use of the crushing mechanism. The dehydrated and crushed raw materials can be quickly dried by a heating dryer, thereby improving the drying efficiency.

[0006] In order to achieve the above-mentioned object, the present invention provides a multifunctional biofuel raw material processing equipment, the equipment comprising: a heating dryer, a feeder vertically fixed above the heating dryer, and a pre-dehydration mechanism vertically fixed between the heating dryer and the feeder and connected to the two;

[0008] The interlayer of the solidifier is filled with liquid nitrogen, and its upper and lower ends are respectively connected with the interior of the feeder and the dehydration box. The feeder and the dehydration box are respectively provided with a No. 1 crushing mechanism and a No. 2 crushing mechanism. A filter cover is vertically fixed at the feed inlet of the dehydration box above the No. 2 crushing mechanism, and at least two suction fans are horizontally connected and fixed on both sides of the dehydration box above the filter cover, and the output end of each suction fan is fixed with a discharge pipe connected to the interior of the heating dryer, so that the crushed raw materials can be screened by the filter cover and transported to the heating dryer for heating and drying treatment.

[0009] Preferably, a plurality of mutually staggered material guide plates are fixedly arranged at both sides of the solidifier and tilted downward, an air outlet pipe and an air inlet pipe are fixedly arranged horizontally on the solidifier, and switch valves are fixedly arranged on the air outlet pipe and the air inlet pipe.

[0010] Preferably, the No. 1 crushing mechanism and the No. 2 crushing mechanism have the same structure, and the No. 1 crushing mechanism comprises: two crushing shafts horizontally and rotatably arranged in the feeder, and a plurality of rows of crushing knives staggered with each other are vertically fixed on the two crushing shafts.

[0011] Preferably, the device further comprises a driving mechanism for driving the first crushing mechanism and the second crushing mechanism to operate synchronously, the driving mechanism comprising a first gear, a second gear, a driving motor and a belt; wherein,

[0012] The ends of the two crushing shafts of the No. 1 crushing mechanism and the No. 2 crushing mechanism located on the same side partially pass through the feeder or the dewatering box horizontally and are coaxially fixed with a No. 1 gear and a No. 2 gear that are meshed with each other, and the two adjacent crushing shafts of the No. 1 crushing mechanism and the No. 2 crushing mechanism are connected by a belt through a pulley transmission, and the end of any one of the crushing shafts of the No. 1 crushing mechanism is coaxially connected to the driving motor horizontally fixed on the feeder through a coupling.

[0013] Preferably, two feed hoppers with openings facing upward and connected to the interior are vertically fixed on both sides of the heating dryer located directly below the two suction fans, and the discharge end of each discharge pipe partially extends vertically downward into the opening of the feed hopper.

[0014] Preferably, the inner wall of the heating dryer is evenly and fixedly provided with a plurality of heating resistance wires for heating the material inside the heating dryer.

[0015] Preferably, a stirring mechanism is provided inside the heating dryer, and the stirring mechanism comprises: a stirring shaft, stirring blades and a stirring motor; wherein,

[0016] A stirring shaft is vertically and rotatably arranged inside the heating dryer, and a plurality of stirring blades are evenly and horizontally fixedly arranged on the stirring shaft. The top end portion of the stirring shaft passes through the top end of the heating dryer and is coaxially connected to the output shaft of the stirring motor vertically fixed on the top of the heating dryer through a coupling.

[0017] Preferably, a feeding end connected to the interior of the feeder is vertically fixed on the top of the feeder.

[0018] According to the above technical solution, the multifunctional biofuel raw material processing equipment provided by the present invention has the following beneficial effects when used:

[0019] (1) The straw raw material is put into the feeder, and the raw material is preliminarily crushed by the first crushing mechanism in the feeder. The preliminarily crushed raw material falls into the solidifier under the action of its own gravity. The liquid flowing out of the raw material during the crushing process is rapidly solidified and frozen by the cooling effect of the liquid nitrogen in the solidifier, and falls into the dehydration box. The raw material is crushed for the second time by the second crushing mechanism in the dehydration box. In the process of crushing the frozen raw material by the second crushing mechanism, the advantages are as follows:

[0020] Advantage 1: Due to the frozen raw materials, there will be no raw materials sticking to the surface of the crushing shaft and the crushing knife of the No. 2 crushing mechanism during the crushing process. Compared with the existing method, there is no need to regularly clean the raw materials entangled on the crushing mechanism, otherwise it will affect the normal use of the crushing mechanism and the crushing effect.

[0021] Advantage 2: The raw materials after freezing show "low temperature brittleness" at low temperature, that is, as the temperature decreases, the hardness and brittleness of the material increase, while the plasticity and toughness decrease. This change in physical properties allows the material to be crushed with a smaller force at a certain temperature, which plays a role in protecting the crushing mechanism and extending its service life.

[0022] Advantage three: During the crushing process, the ice debris condensed on the surface of the fine raw materials after secondary crushing or falling on the bottom of the dehydration box together with the raw materials will cause the ice debris to separate from the raw materials, so as to separate the raw materials from the ice debris, thereby realizing the function of dehydrating the raw materials.

[0023] (2) When ice slag condensed on the surface of the fine raw materials after secondary crushing or falls on the bottom of the dehydration box together with the raw materials, the ice slag will be separated from the raw materials. Since the raw materials after crushing are very small and weigh less than the ice slag, the suction fan is started to suck the crushed raw materials through the filter cover into the heating dryer for secondary dehydration. During the operation, the suction fan can suck the raw materials falling on the bottom of the dehydration box from bottom to top. In the process of raw materials, large particles of raw materials can be crushed again through the second crushing mechanism to obtain smaller particles of raw materials, and small particles of raw materials pass through the filter cover and the suction fan into the heating dryer for secondary dehydration. After multiple crushing, the small particles of raw materials enter the heating dryer and can be quickly dried. The large particles of raw materials are filtered by the filter cover in the dehydration box and crushed by the second crushing mechanism to obtain small particles of raw materials.

[0024] (3) By intermittently starting the suction fan, the raw materials can be fully crushed in cooperation with the No. 2 crushing mechanism to obtain smaller raw material particles. The reason is that when the suction fan is working, the raw materials that fall on the bottom of the dehydration box can be sucked from the bottom to the top. The raw materials with large particles can be crushed again by the No. 2 crushing mechanism to obtain smaller raw materials. The small particles of raw materials pass through the filter cover and the suction fan into the heating dryer for secondary dehydration. The large particles of raw materials are filtered by the filter cover in the dehydration box. When the suction fan stops working, the large particles of raw materials will fall to the bottom of the dehydration box. Starting the fan again can suck the large and small particles of raw materials onto the filter cover. When the large particles are rising, they pass through the No. 2 crushing mechanism again. Repeat the above operation. So that the No. 2 crushing mechanism can crush the raw materials inside it into small particles that meet the requirements of passing through the filter cover.

[0025] In summary, the present invention can achieve rapid dehydration through the pre-dehydration mechanism, and in the process of dehydration, can realize the function of multi-stage crushing, and in the process of crushing, it can avoid the raw materials being entangled in the crushing mechanism and affecting the normal use of the crushing mechanism. The dehydrated and crushed raw materials can be quickly dried by the heating dryer, thereby improving the drying efficiency.

[0035] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0036] like Figure 1-5As shown, the present invention provides a multifunctional biofuel raw material processing equipment, the equipment comprising: a heating dryer 1, a feeder 2 vertically fixed above the heating dryer 1, and a pre-dehydration mechanism vertically fixed between the heating dryer 1 and the feeder 2 and connected to the two;

[0037] The pre-dehydration mechanism includes, from top to bottom, a coagulator 3 and a dehydration box 4; wherein,

[0038] The interlayer of the solidifier 3 is filled with liquid nitrogen, and its upper and lower ends are respectively connected with the interior of the feeder 2 and the dehydration box 4. The feeder 2 and the dehydration box 4 are respectively provided with a No. 1 crushing mechanism 5 and a No. 2 crushing mechanism 6. A filter cover 18 is vertically fixed at the feed inlet of the dehydration box 4 above the No. 2 crushing mechanism 6, and at least two suction fans 8 are horizontally connected and fixed on both sides of the dehydration box 4 above the filter cover 18, and the output end of each suction fan 8 is fixedly provided with a discharge pipe 10 connected with the interior of the heating dryer 1, so that the crushed raw materials can be transported to the heating dryer 1 for heating and drying treatment after screening by the filter cover 18.

[0039] In the above scheme, the straw raw material is put into the feeder 2, and the raw material is preliminarily crushed by the No. 1 crushing mechanism 5 in the feeder 2. The preliminarily crushed raw material falls into the solidifier 3 under the action of its own gravity. Through the cooling effect of the liquid nitrogen in the solidifier 3 (the temperature of the liquid nitrogen is generally -195.79°C), the preliminarily crushed raw material enters and the liquid flowing out of the raw material during the raw material crushing process is quickly solidified and frozen, and falls into the dehydration box 4. It enters the No. 2 crushing mechanism 6 in the dehydration box 4 for secondary crushing. In the process of the No. 2 crushing mechanism 6 crushing the frozen raw material, the following advantages are included:

[0040] Advantage 1: Due to the frozen raw materials, there will be no raw materials sticking to the surface of the crushing shaft and the crushing knife of the No. 2 crushing mechanism 6 during the crushing process. Compared with the existing method, there is no need to regularly clean the raw materials entangled on the crushing mechanism, otherwise it will affect the normal use of the crushing mechanism and the crushing effect.

[0041] Advantage 2: The raw materials after freezing show "low temperature brittleness" at low temperature, that is, as the temperature decreases, the hardness and brittleness of the material increase, while the plasticity and toughness decrease. This change in physical properties allows the material to be crushed with a smaller force at a certain temperature, which plays a role in protecting the crushing mechanism and extending its service life.

[0042] Advantage three: During the crushing process, the ice debris condensed on the surface of the fine raw materials after secondary crushing or falling on the bottom of the dehydration box 4 together with the raw materials will cause the ice debris to separate from the raw materials, so as to separate the raw materials from the ice debris, thereby realizing the function of dehydrating the raw materials.

[0043] In addition, when the ice slag condensed on the surface of the fine raw materials after secondary crushing or falls on the bottom of the dehydration box 4 together with the raw materials, the ice slag will be separated from the raw materials. Since the raw materials after crushing are very small and weigh less than the ice slag, the suction fan 8 is started to suck the crushed raw materials into the heating dryer 1 through the filter cover 18 for secondary dehydration. During the operation, the suction fan 8 can suck the raw materials falling on the bottom of the dehydration box 4 from bottom to top. In the process of raw materials, the raw materials with large particles can be crushed again through the second crushing mechanism 6 to obtain smaller particles of raw materials, and the raw materials with small particles pass through the filter cover 18 and the suction fan 8 into the heating dryer 1 for secondary dehydration. The small particles of raw materials after multiple crushing enter the heating dryer 1 and can be quickly dried. The large particles of raw materials are filtered by the filter cover 18 in the dehydration box 4 and crushed by the second crushing mechanism 6 to obtain small particles of raw materials.

[0044] In addition, by intermittently starting the suction fan 8, the raw materials can be fully crushed in cooperation with the No. 2 crushing mechanism 6 to obtain smaller raw material particles. The reason is that when the suction fan 8 is working, the raw materials falling on the bottom of the dehydration box 4 can be sucked away from the bottom to the top. The raw materials with large particles can be crushed again through the No. 2 crushing mechanism 6 to obtain smaller raw materials, and the small particles of raw materials pass through the filter cover 18 and the suction fan 8 into the heating dryer 1 for secondary dehydration, and the large particles of raw materials are filtered by the filter cover 18 in the dehydration box 4. When the suction fan 8 stops working, the large particles of raw materials will fall to the bottom of the dehydration box 4. Starting the fan 8 again can suck the large and small particles of raw materials into the filter cover 18, and the large particles will pass through the No. 2 crushing mechanism 6 again during the process of rising, and the above operation is repeated. So that the No. 2 crushing mechanism 6 can crush the raw materials inside it into small particles that meet the requirements of passing through the filter cover 18.

[0045] In a preferred embodiment of the present invention, a plurality of guide plates 7 are fixedly arranged on both sides of the interior of the solidifier 3 and are staggered with each other and tilted downward, an air outlet pipe 14 and an air inlet pipe 15 are fixedly arranged horizontally on the solidifier 3, and switch valves are fixedly arranged on the air outlet pipe 14 and the air inlet pipe 15.

[0046] In the above scheme, the purpose of the multiple guide plates 7 arranged obliquely is:

[0047] On the one hand, the time for the crushed material from the feeder 2 to enter the solidifier 3 is prolonged so that the raw materials after the initial crushing can have a sufficiently long time to solidify in the solidifier 3. On the other hand, when the raw materials slide downward along the guide plate 7, the ice debris condensed on the surface of the raw materials can separate from the surface of the raw materials when colliding with the guide plate 7.

[0048] In addition, the air inlet pipe 15 is connected to a liquid nitrogen source, and liquid nitrogen is supplied to the interlayer of the solidifier 3 through the air inlet pipe 15 to keep the temperature in the solidifier 3 below zero, so as to solidify and freeze the raw material and the liquid flowing out of the raw material during the raw material crushing process.

[0049] The gas outlet pipe 14 is used to discharge the liquid ammonia in the interlayer of the coagulator 3. Of course, the gas outlet pipe 14 can also be removed and replaced by the gas inlet pipe 15 to achieve the same function.

[0051] In the above scheme, the two crushing rollers are driven to move toward each other, so as to drive the crushing knives on the two crushing rollers to crush the raw materials in the feeder 2 or the raw materials in the dewatering box 4. The small particle raw materials after multiple crushing enter the heating dryer 1 and can be quickly dried.

[0052] In a preferred embodiment of the present invention, the device further comprises a driving mechanism 12 for driving the first crushing mechanism 5 and the second crushing mechanism 6 to operate synchronously, and the driving mechanism 12 comprises a first gear, a second gear, a driving motor and a belt 13; wherein,

[0054] In the above scheme, when in use, the driving motor is started to rotate the crushing shaft of the No. 1 crushing mechanism 5 connected to its output shaft, and under the meshing relationship between the No. 1 gear and the No. 2 gear, the other crushing shaft of the No. 1 crushing mechanism 5 is driven to rotate, so that the two crushing shafts of the No. 1 crushing mechanism 5 rotate towards each other, so as to perform preliminary crushing of the raw materials inside through the multiple rows of crushing knives on the two.

[0055] In addition, under the transmission action of the belt 13 and the meshing action of the No. 1 gear and the No. 2 gear on the two crushing shafts of the No. 2 crushing mechanism 6, while the No. 1 crushing mechanism 5 is running, it can drive the two crushing shafts of the No. 2 crushing mechanism 6 to rotate so as to perform secondary crushing on the raw materials inside through the multiple rows of crushing knives on the two, thereby improving the crushing effect and crushing the raw materials more fully.

[0056] In a preferred embodiment of the present invention, two feed hoppers 9 with openings facing upward and connected to the interior are vertically fixed on both sides of the heating dryer 1 directly below the two suction fans 8, and the discharge end of each of the discharge pipes 10 partially extends vertically downward into the opening of the feed hopper 9.

[0057] In the above scheme, when in use, the crushed raw materials can be sucked into the discharge pipe 10 through the filter cover 18 by the suction fan 8 and the crushed raw materials are transported to the heating dryer 1 through the feed hopper 9.

[0058] In a preferred embodiment of the present invention, a plurality of heating resistance wires 16 for heating the material inside the heating dryer 1 are evenly and fixedly arranged on the inner wall of the heating dryer 1 .

[0059] In the above scheme, the heating resistor 16 is connected to electricity to heat the inside of the heating dryer 1, and the heating resistor 16 is a well-known technical means, so its specific structure and use principle will not be repeated here.

[0060] In a preferred embodiment of the present invention, a stirring mechanism 17 is provided inside the heating dryer 1, and the stirring mechanism 17 includes: a stirring shaft, a stirring blade and a stirring motor; wherein,

The top end portion of the stirring shaft passes through the top end of the heating dryer 1 and is coaxially connected to the output shaft of the stirring motor vertically fixed on the top of the heating dryer 1 through a coupling.

[0062] In the above scheme, when in use, the stirring motor is started to drive the stirring shaft and all the stirring blades on the stirring shaft to rotate, so as to evenly stir the crushed raw materials entering the heating dryer 1, so that the heating dryer 1 can evenly and fully heat and dry the crushed raw materials inside it, realizing the secondary dehydration operation.

[0063] In a preferred embodiment of the present invention, a feeding end 11 communicating with the interior of the feeder 2 is vertically fixedly disposed on the top of the feeder 2.

[0064] In the above solution, the raw material is put into the feeder 2 through the feed end 11.

[0065] In summary, the multifunctional biofuel raw material processing equipment provided by the present invention overcomes the problem in the prior art that straw as raw material needs to be crushed by a crusher, and then the crushed raw material needs to be transported to a dehydrator for dehydration, which requires multiple equipment for processing during the processing, resulting in cumbersome operation, reduced work efficiency, and increased processing costs.
