Description
Technical Field
[0001] The utility model relates to the technical field of biomass particle processing, in particular to a wood crushing and drying device. Background Art
[0002] The wood crushing and drying device for biomass pellet processing first performs preliminary mechanical crushing on the waste generated by the factory's production of wooden pallets to make it smaller blocks or strips. The materials that have undergone preliminary crushing will then be further crushed. At this stage, the wood will be further crushed into finer particles or powder. The crushed powder will then be transported to the drying equipment for drying through a conveying device. The dried material can then be used to prepare biomass pellets.
[0003] Existing wood waste is directly transported to the drying equipment through a conveyor belt after being fully crushed. Since the feed amount and crushing speed of the wood waste cannot be kept constant, the discharge rate of the powder produced after crushing cannot be kept consistent, resulting in differences in the amount of powder material entering the dryer per unit time, which in turn leads to certain differences in the moisture content of the materials after being dried by the drum drying equipment. Utility Model Content
[0004] The utility model aims to provide a wood crushing and drying device, which can achieve the effect of reducing the difference in water content between powder materials after drying.
[0005] The above technical purpose of the utility model is achieved through the following technical scheme: a wood crushing and drying device, including a crushing body, a drying body, a feeding bracket obliquely arranged between the crushing body and the drying body, two conveying rollers rotatably arranged on the feeding bracket and a conveyor belt arranged between the two conveying rollers, a material laying bracket is arranged on the feeding bracket, a first pushing plate is arranged on the material laying bracket in a direction perpendicular to the conveyor belt, the bottom end of the first pushing plate is parallel to the conveyor belt, and there is a set distance between the bottom end of the first pushing plate and the conveyor belt.
[0006] The utility model is further configured as follows: a dust cover with openings on both sides is arranged on the material laying bracket, a first air supply pipe and a second air supply pipe are relatively arranged on the inner walls on both sides of the dust cover, a plurality of first air blowing pipes are evenly arranged on the first air supply pipe, and a plurality of second air blowing pipes are evenly arranged on the second air supply pipe.
[0007] The utility model is further configured as follows: the first air supply pipe and the second air supply pipe are both parallel to the conveyor belt.
[0008] The utility model is further configured as follows: the first air blowing pipe and the second air blowing pipe are both arranged in an inclined downward direction.
[0009] The utility model is further configured as follows: the air outlet directions of the first air blowing pipe and the second air blowing pipe are perpendicular to each other.
[0010] The utility model is further configured as follows: a second push plate is arranged on the material laying bracket in a direction parallel to the first push plate, a set distance is provided between the bottom end of the second push plate and the conveyor belt, the first push plate is located between the crushing body and the first air supply pipe, and the second push plate is located between the first air supply pipe and the drying body.
[0011] The utility model is further configured as follows: one side of the first push plate is fixedly connected to one side opening of the dust cover, and one side of the second push plate is fixedly connected to the other side opening of the dust cover.
[0012] The utility model is further configured as follows: first material baffle plates are arranged opposite to each other on both sides of the material conveying bracket, and a side of the first material baffle plate away from the crushing machine body is fixedly connected to the first material pushing plate.

[0014] The utility model is further configured as follows: a second material blocking plate is disposed obliquely upward at the top end of the first material pushing plate.
[0015] The beneficial effects of the utility model are:
[0016] 1. By setting a first push plate whose bottom is parallel to the conveyor belt, and adjusting the distance between the first push plate and the conveyor belt to an appropriate level, after the powder material discharged from the crushing body enters the conveyor belt and is transported to the first push plate, part of the material continues to be transported forward into the drying body along the conveyor belt through the gap between the bottom end of the first push plate and the conveyor belt, and the excess material will be blocked by the first push plate and cannot be transported forward further. Only after the subsequent discharge amount of the crushing body is reduced, the excess material will continue to be transported forward; therefore, through the blocking of the first push plate, the amount of material that can pass through the first push plate and the conveyor belt remains relatively constant, and then the amount of powder material entering the drying body per unit time remains relatively constant, thereby achieving the purpose of reducing the difference in water content of the dried powder material.
[0017] 2. By setting up a dust cover, a first air supply pipe and a second air supply pipe, after the powder material enters the dust cover through the first push plate, the air blown out from the first air blow pipe and the second air blow pipe on both sides makes the powder material mainly located in the middle of the conveyor belt move to both sides of the conveyor belt, so that the powder material is more evenly distributed on the conveyor belt, the material is dispersed, and the effect of subsequent drying is improved.
[0018] 3. By setting the first baffle plate and the second baffle plate, it is prevented that too much powder material is blocked by the first push plate, so that the powder material falls from both sides of the conveyor belt and the top of the first push plate. When too much material is accumulated at the first push plate, the workers can also reduce the material production speed of the crushing body in time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0024] The technical solution of the utility model will be described clearly and completely below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of 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.
[0025] The utility model provides a wood crushing and drying device, such as Figures 1 to 3As shown, it includes a crushing body, a drying body, a feeding bracket 1 obliquely arranged between the crushing body and the drying body, two conveying rollers 2 rotatably arranged on the feeding bracket 1, and a conveyor belt 3 arranged between the two conveying rollers 2, a material laying bracket 4 is arranged on the feeding bracket 1, and a first pushing plate 5 is arranged on the material laying bracket 4 in a direction perpendicular to the conveyor belt 3, the bottom end of the first pushing plate 5 is parallel to the conveyor belt 3, and there is a set distance between the bottom end of the first pushing plate 5 and the conveyor belt 3.
[0026] Furthermore, the material paving bracket 4 is provided with a dust cover 6 with openings on both sides, and the first air supply pipe 7 and the second air supply pipe 8 are relatively arranged on the inner walls on both sides of the dust cover 6, and a plurality of first air blowing pipes 9 are evenly arranged on the first air supply pipe 7, and a plurality of second air blowing pipes 10 are evenly arranged on the second air supply pipe 8.
[0027] Furthermore, the first air supply pipe 7 and the second air supply pipe 8 are both parallel to the conveyor belt 3 .
[0028] Furthermore, the first air blowing pipe 9 and the second air blowing pipe 10 are both arranged in an inclined downward direction.
[0029] Furthermore, the air outlet directions of the first air blowing pipe 9 and the second air blowing pipe 10 are perpendicular to each other.
[0030] Furthermore, a second push plate 11 is arranged on the material laying bracket 4 in a direction parallel to the first push plate 5, and a set distance is provided between the bottom end of the second push plate 11 and the conveyor belt 3. The first push plate 5 is located between the crushing body and the first air supply pipe 7, and the second push plate 11 is located between the first air supply pipe 7 and the drying body.
[0031] Further, one side of the first push plate 5 is fixedly connected to one opening of the dust cover 6 , and one side of the second push plate 11 is fixedly connected to the other opening of the dust cover 6 .
[0032] Furthermore, first material baffle plates 12 are oppositely arranged on both sides of the material conveying bracket 1 , and the side of the first material baffle plate 12 away from the crushing machine body is fixedly connected to the first pushing plate 5 .
[0033] Furthermore, the cross section of the conveyor belt 3 is V-shaped.
[0034] Furthermore, a second material blocking plate 13 is disposed obliquely upward at the top end of the first pushing plate 5 .
[0035] During the production process, the powder material coming out of the crusher body (the crusher body includes a crushing chamber, two counter-rotating crushing rollers and a hammer head, etc., and the drying body includes a drum drying body and a heating device, etc., all of which are prior arts, so they will not be described in detail and will not affect the technical scope actually protected by this application) enters the conveyor belt 3, and is transported to the first push plate 5. Part of the material enters the dust cover 6 through the gap between the bottom end of the first push plate 5 and the conveyor belt 3. The multiple first air blowing pipes 9 and the second air blowing pipes 10 on the first air supply pipe 7 and the second air supply pipe 8 blow air relatively obliquely downward at the powder material in the middle of the conveyor belt 3, so that the powder material moves to both sides of the conveyor belt 3. After that, the powder material blown away on the conveyor belt 3 passes through the gap between the second push plate 11 and the conveyor belt 3 (it should be noted that the gap between the second push plate 11 and the conveyor belt 3 is smaller than the gap between the first push plate 5 and the conveyor belt 3 , so that the agglomerated powder materials that may exist in the middle of the conveyor belt 3 stay in the dust cover 6 and are further blown up to be dispersed), and continue to be transported forward into the drying machine body with the conveyor belt 3. The excess materials will be blocked by the first push plate 5 and cannot be transported forward. After the subsequent discharge of the crushing machine body is reduced, the excess materials will continue to be transported forward; therefore, through the blocking of the first push plate 5 and the second push plate 11, the amount of material that can pass through the first push plate 5 and the conveyor belt 3 is kept relatively constant, and then the amount of powder materials entering the drying machine body per unit time is kept relatively constant, thereby achieving the purpose of reducing the difference in water content of the dried powder materials; at the same time, through the relatively arranged first air supply pipe 7 and the second air supply pipe 8, the powder materials are distributed more evenly on the conveyor belt 3, and the materials that may be agglomerated can be dispersed, thereby improving the effect of subsequent drying.
[0036] By setting the first baffle plate 12 and the second baffle plate 13, it is prevented that too much powder material is blocked by the first push plate 5, so that the powder material falls from both sides of the conveyor belt 3 and the top of the first push plate 5. When too much material is accumulated at the first push plate 5, the workers can also reduce the material production speed of the crushing body in time.
[0037] The dust cover 6 is provided, and the first push plate 5 and the second push plate 11 are respectively located on both sides of the dust cover 6, so as to prevent the air blown from the first air blowing pipe 9 and the second air blowing pipe 10 from scattering the powder material everywhere, thereby causing the loss of the material.
[0038] By setting the cross section of the conveyor belt 3 to be V-shaped, the powder material produced by the crushing body is prevented from scattering from both sides of the conveyor belt 3 after entering the conveyor belt 3, causing material loss. It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same and similar parts between the various embodiments can be referred to each other.
[0039] The above description is only a description of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention. Any changes or modifications made by a person skilled in the art in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
