Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in the figure, the utility model provides a kind of crop dryer heat pump, it comprises pump case 1, pump case 1 is provided with air inlet 1.1, described air inlet 1.1 is connected with the space residing for the evaporimeter 3 in pump case 1, described air inlet 1.1 is provided with filter course 2, filter course 2 comprises framework 2.1, to be located in framework 2.1 and the plane that framework 2.1 surrounds to be divided into the footpath bar 2.3 of some air inlet unit 2.2, the cloth-bag type screen pack 2.4 of a covering air inlet unit 2.2 is equipped with in each air inlet unit 2.2, the edge of the openend 2.4.1 of cloth-bag type screen pack 2.4 and the edge of air inlet unit 2.2 are fixed.So-called cloth-bag type, refers to the stereochemical structure with openend, and its inner chamber is communicated with by openend with space outerpace, is similar in cloth bag.The edge of the openend 2.4.1 of cloth-bag type screen pack 2.4 and the edge of air inlet unit 2.2 fixedly refer to, openend 2.4.1 is communicated with the side of air inlet unit 2.2, and the edge of the edge of openend 2.4.1 and air inlet unit 2.2 is fixed and sealed, make the air of the side of air inlet unit 2.2 must need just can be entered by the mesh on cloth-bag type screen pack 2.4 opposite side of air inlet unit 2.2 thus.
