[0049] It is found through research that the continuous fluidized bed dryer has the advantages of high efficiency, energy saving, environmental protection, large processing capacity and the like, and is a drying equipment with excellent performance, which plays an important role in material drying treatment in many industries. After granulation of powder, the granular material is relatively moist during molding, and therefore a continuous fluidized bed dryer needs to be used to dry the mixture of moist granular material and powder. However, in the process of drying the granular material by using the existing continuous fluidized bed dryer, some moist powder and dried powder are blown by hot air. A cyclone separator is generally used to collect the powder taken away by the hot air, but it is difficult to dry the moist powder in time after the powder is collected by the cyclone separator.
[0050] Based on the above research, the embodiment of the present disclosure provides a continuous fluidized bed dryer. The filter mechanism is provided and cooperates with the material drying mechanism. The filter mechanism intercepts the powder blown by the hot air. With continuous starting of the material drying mechanism, the hot air continuously passes through the intercepted powder and is discharged to the outside of the machine body. In this process, the intercepted material is continuously dried, so that the dried material can be directly obtained after work is completed.
[0051] The defects of the above solutions are the results of the practical research of the utility model person, and therefore the discovery process of the above problems and the solutions of the present disclosure to the above problems should be the contribution of the utility model person to the present disclosure in the process of the present disclosure.
[0052] It should be noted that similar reference numerals and letters refer to similar items throughout the accompanying drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.
[0053] Some embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. In the case of no conflict, the embodiments described below and the features in the embodiments can be combined with each other.
[0054] In some embodiments, as shown in Figure 1 The mixture of particles and powder to be dried is fed from the material inlet 12 and falls onto the material conveying net 11, at which time the vibration motor 20 is started to continuously reciprocatingly vibrate the material conveying net 11, thereby causing the mixture on the material conveying net 11 to be conveyed inside the body 6.
[0055] In some embodiments, as shown in Figure 2 During the conveying of the mixture, the air heater 31 and the pump 30 are simultaneously started. The pump 30 draws air which is heated by the air heater 31, and the heated air is introduced into the lower chamber 2 inside the body 6 through the air pipe 32. The heated air continuously flows into the body 6 from the lower chamber 2 to the upper chamber 1, passes through the material conveying net 11 in the flow process, and dries the particles in the mixture and simultaneously carries away the wet or dry powder in the mixture. The powder carried by the heated air moves to the outside of the cloth bag 40 and is intercepted. The heated air passing through the powder and the cloth bag 40 is discharged along the F1 direction through the exhaust valve 43. The air continuously flows, continuously dries the powder intercepted by the cloth bag 40, and then after the completion of the drying of the entire material, the operator only needs to discharge the air in the air bag 42, which is sprayed out of each air jet 41 (for the air bag, the source of the gas in the air bag is the total compressed air pipe outside which introduces compressed air into the air bag, and a pulse electromagnetic valve is added at the output end of the air bag to control the air output, which is a prior art and will not be described in detail here). As can be seen from the figure, each air jet 41 extends into the inside of the corresponding cloth bag 40. When the gas is sprayed out of the air jet 41, the dry powder intercepted on the outer wall of the cloth bag 40 is blown off for the operator to collect, and at this time the collected powder is dry powder.
[0056] In some embodiments, as shown in Figure 3 In order to avoid the vibration of the entire device caused by the start of the vibration motor 20, which reduces the service life of the remaining components, the upper chamber 1 and the lower chamber 2 are connected by a soft connection. With the start of the vibration motor 20, the vibration is isolated through the soft connection 5 between the upper chamber 1 and the lower chamber 2 to protect the components in the upper chamber 1. The setting of the shock-absorbing spring 21 reduces the vibration and noise of the body 6 during operation, further improves the stability and service life of the equipment.
[0057] In the description of the embodiments of the utility model, unless there is definite stipulation and limitation, the terms "mount", "connect", "connection" should be understood in broad sense, for example, it can be fixed connection, also can be detachable connection, or integrally connected, it can be mechanical connection, also can be electrical connection, it can be direct connection, also can be indirect connection through intermediate medium, it can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to specific circumstances.
[0058] In the description of the utility model, it needs to be explained that the orientation or position relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as limiting the utility model. In addition, terms such as "first", "second" and other numerical terms are used in this document, unless otherwise indicated in this document. Therefore, the above-discussed first element, component, region, layer or section can be referred to as the second element, component, region, layer or section without departing from the teachings of the example embodiments.
[0059] Spatially relative terms, such as "inner", "outer", "beneath", "below", "lower", "above", "upper" and the like, can be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. The spatially relative terms can be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the example term "below" can encompass both an orientation of above and below. The device can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
[0060] In the above discussion, unless otherwise stated, the terms "about", "approximately", "substantially" and the like, when used in describing numerical values, mean a + / - 10% variation of the value.
[0061] With the above ideal embodiments according to the utility model as inspiration, through the above description, relevant staff can definitely make various changes and modifications without deviating from the technical idea of the utility model. The technical scope of the utility model is not limited to the contents in the specification, and the technical scope must be determined according to the scope of claims.
