具体实施方式Detailed ways

以下结合附图,对本实用新型的具体实施方式作进一步详述,以使本实用新型技术方案更易于理解和掌握。Below in conjunction with the accompanying drawings, the specific implementation of the utility model will be further described in detail, so as to make the technical solution of the utility model easier to understand and grasp.

实施例:参照图1所示,参见图1-3所示,本实施例提供一种食用菌烘干机,包括箱体1和若干平行设于箱体1内的置料筛板2,箱体1内下部设有一个水平设置的电热网3;箱体1的下外侧壁上设有一个输出端伸入箱体1内底部的鼓风机4,箱体1内下部还设有块隔板5,其中隔板5位于鼓风机4的输出端和电热网3之间;隔板5内部具有一个空腔51;隔板5上竖直设有若干导风管52,其中导风管52的上端和下端分别贯穿隔板5的上表面和下表面;导风管52内可拆卸连接有一个用于过滤灰尘的过滤机构53;箱体1的侧壁内嵌有一根排湿管6,其中排湿管6的上端位于箱体1内上部且与箱体1内部连通,下端与空腔51连通;隔板5的左端设有一个出气管54,其中出气管54的一端与空腔51连通,另一端伸出箱体1外。Embodiment: As shown in Fig. 1, referring to Fig. 1-3, this embodiment provides an edible fungus drying machine, which includes a box body 1 and several material sieve plates 2 arranged in parallel in the box body 1, and the box body 1 The lower part of the body 1 is provided with a horizontally arranged electric heating network 3; the lower outer wall of the box body 1 is provided with a blower 4 whose output end extends into the bottom of the box body 1, and the lower part of the box body 1 is also provided with a partition plate 5 , wherein the partition 5 is located between the output end of the blower 4 and the electric heating network 3; the partition 5 has a cavity 51 inside; the partition 5 is vertically provided with several air guide pipes 52, wherein the upper end of the air guide pipe 52 and The lower end runs through the upper surface and the lower surface of the partition 5 respectively; a filter mechanism 53 for filtering dust is detachably connected to the air duct 52; The upper end of the pipe 6 is located at the upper part of the box body 1 and communicates with the inside of the box body 1, and the lower end communicates with the cavity 51; One end stretches out of the box body 1.

过滤机构53包括一个上端敞口且呈管状的过滤网筒531;导风管52的部内管壁上具有螺纹区,过滤网筒531的上部外侧壁上固定连接有一个环状的连接块532,其中连接块532的外侧壁上具有与导风管52内管壁上螺纹区适配的螺纹段。管状的过滤网筒531可以大大增大过滤面积;过滤网筒531长期大的使用,有可能过滤网筒531上的网眼会被堵塞,所以需要定期将过滤网筒531从导风管52内抽下,需要取下过滤网筒531时,由于过滤网筒531是通过连接块532螺纹连接在导风管52内的,所以,只需要旋转过滤网筒531即可将过滤网筒531取下,安装时同理。The filter mechanism 53 includes an open upper end and a tubular filter screen cylinder 531; the inner pipe wall of the air guide pipe 52 has a threaded area, and an annular connection block 532 is fixedly connected to the upper outer side wall of the filter screen cylinder 531. Wherein, the outer wall of the connecting block 532 has a threaded section adapted to the threaded area on the inner pipe wall of the air guide pipe 52 . The tubular filter cylinder 531 can greatly increase the filtering area; if the filter cylinder 531 is used for a long time, the mesh on the filter cylinder 531 may be blocked, so the filter cylinder 531 needs to be drawn out from the air duct 52 regularly. Next, when the filter screen cylinder 531 needs to be removed, since the filter screen cylinder 531 is screwed into the air duct 52 through the connection block 532, the filter screen cylinder 531 can be removed only by rotating the filter screen cylinder 531. The same applies to installation.

箱体1的内部两侧的侧壁对称设有安装块22,安装块22相对的侧面上具有滑槽;置料筛板2的两侧的侧壁上对称固定连接有滑块21;置料筛板2通过滑块21滑动连接在滑槽内。通过滑块21和滑槽,可以方便的将置料筛板2取下或安装到箱体1内。The side walls on both sides of the inside of the box body 1 are symmetrically provided with mounting blocks 22, and there are chute on the opposite side of the mounting block 22; the side walls on both sides of the material sieve plate 2 are symmetrically fixedly connected with slide blocks 21; The sieve plate 2 is slidably connected in the chute through the slider 21 . Through the slide block 21 and the chute, the material sieve plate 2 can be easily removed or installed into the box body 1 .

箱体1内下部还设有一块挡料板7,其中挡料板7位于最下方的置料筛板2和电热网3之间;挡料板7的板面上具有若干出气通孔。再将食用菌放入到箱体1内时,有可能出现一些食用菌掉入箱底,所以设置挡料板7防止这些掉落的食用菌掉到电热网3,影响设备的正常工作。The lower part of the box body 1 is also provided with a baffle plate 7, wherein the baffle plate 7 is located between the bottom sieve plate 2 and the electric heating net 3; the plate surface of the baffle plate 7 has a number of air outlet through holes. When the edible fungus is put into the casing 1 again, some edible fungi may fall into the bottom of the case, so the baffle plate 7 is set to prevent these dropped edible fungi from falling into the electric heating network 3, which will affect the normal operation of the equipment.

箱体1的下部还设有滚轮8。设置滚轮8的目的在于便于移动烘干机。The bottom of the casing 1 is also provided with rollers 8 . The purpose of setting the roller 8 is to facilitate the movement of the dryer.

工作原理:首先将置料筛板2抽下(其原理类似于抽屉),将食用菌放入置料筛板2内,装料结束后,再将置料筛板2安装到箱体1内;关闭箱门(箱门是常规设计,所以在图中和前文中未示出)。烘干时,鼓风机4向箱体1内下部鼓风,进入箱体1内的风会从导风管52向上导出,再经过电热网3加热形成热风对食用菌进行烘干;烘干产生的高温湿气会通过排湿管6排入隔板5内部的空腔51内,从而使空腔51内的温度提高,从而使后续通过导风管52导入的风被预热升温,预热后的风再次被电热网3加热,从而可以节省资源,做到资源充分有效的利用。由于鼓风机4是将外部空气带入箱体1内的,这些空气中会有比较大的灰尘,所以在这些空气进入导风管52时通过过滤网筒531对其进行一次过滤,防止这些灰尘进入箱体1内上部污染食用菌。Working principle: first pull down the material sieve plate 2 (the principle is similar to a drawer), put the edible fungus into the material sieve plate 2, and then install the material sieve plate 2 into the box body 1 after the filling is completed ; Close the door (the door is a conventional design, so it is not shown in the drawings and in the preceding text). During drying, the blower 4 blows air to the lower part of the box body 1, and the wind entering the box body 1 will be guided upwards from the air guide pipe 52, and then heated by the electric heating network 3 to form hot air to dry the edible fungus; The high-temperature moisture will be discharged into the cavity 51 inside the partition 5 through the dehumidification pipe 6, so that the temperature in the cavity 51 will increase, so that the subsequent wind introduced through the air guide tube 52 will be preheated and heated. The wind is heated by the electric heating network 3 again, thereby saving resources and achieving full and effective utilization of resources. Because the blower 4 brings the outside air into the box body 1, there will be relatively large dust in the air, so when the air enters the air guide pipe 52, it is filtered once through the filter screen cylinder 531 to prevent the dust from entering The upper part in the casing 1 pollutes the edible fungus.

当然,以上只是本实用新型的典型实例,除此之外,本实用新型还可以有其它多种具体实施方式,凡采用等同替换或等效变换形成的技术方案,均落在本实用新型要求保护的范围之内。Of course, the above are only typical examples of the utility model. In addition, the utility model can also have other various specific implementation modes. within the range.
