Description

TECHNICAL FIELD

[0001] The utility model relates to drying technical field, especially a kind of multilayer circulating high-efficiency energy-saving drying cabinet with good drying effect and convenient incense stick loading and taking. BACKGROUND

[0002] The manufacturers of incense sticks (also known as wood powder bamboo stick, incense, incense stick, Buddha incense, bamboo stick incense, incense column, mosquito incense, etc.) for fumigation, mostly use the drying method to dry the wood powder on the bamboo stick for the dehumidification treatment of the incense sticks or incense products or pre-products (wood powder not dried bamboo stick) with embossed patterns. If it is cloudy or windy and rainy, production cannot be carried out. The drying method requires a large production site, which is a great cost for enterprises in the current period of high land cost, and the dried incense sticks also need to be collected manually, which is low in work efficiency. Therefore, the applicant has applied for a kind of full-automatic multilayer circulating incense stick high-efficiency energy-saving drying cabinet (CN202211372435.X), which has small floor area, low labor cost, fast drying speed, high drying efficiency, energy saving and is not affected by the weather. When the incense stick runs to the outlet of the lower drying channel, it reaches the drying standard. When the incense stick placing rack runs from the lower drying channel to the front end of the oven body, the incense stick placing rack is tilted forward or turned flat to realize downward pouring, and the output is caught by the belt. This pouring method is high in work efficiency, but it has the following disadvantages: first, the pouring structure increases the complexity of the entire drying cabinet structure, which increases the cost of machines and labor; second, this pouring method inevitably causes some broken incense sticks due to collision. Therefore, further improvement is needed. SUMMARY

[0003] The utility model aims at the above-mentioned problems and deficiencies, provides a kind of energy-saving, high-efficiency, good drying effect, not affected by the weather, small floor area, and loading and taking incense stick are operated at the same end position of drying cabinet, workers do not need to run around, convenient operation, high work efficiency, simple structure, low production cost, convenient incense stick loading and taking multilayer circulating high-efficiency energy-saving drying cabinet.

[0004] The technical scheme of the utility model is realized as follows:

[0005] The utility model discloses a multi -layer circulation formula high -efficient energy -conserving drying box of convenient fragrance stick dress gets, including drying oven body, heating ventilation unit, the extension of at least one layer upper drying channel and at least one layer lower drying channel along the length direction of drying oven body, the closed -loop type conveying chain of connecting upper drying channel and lower drying channel, transmission sprocket, a plurality of fragrance stick rack of the device is arranged on conveying chain in order gap, transmission sprocket and drive arrangement and industrial control box are connected, its characteristics are: the front end panel of drying oven body is equipped with the fragrance stick dress entrance and fragrance stick taking material mouth of the arrangement of up and down, still be connected with a dress fragrance stick displacement controller on industrial control box, can control the position height of fragrance stick rack near fragrance stick dress entrance and near fragrance stick taking material mouth through the dress fragrance stick displacement controller when dress fragrance stick.

[0006] When the movement direction of fragrance stick rack is from below to above circulation in the front end of drying oven body, preferably the fragrance stick taking material mouth is below the fragrance stick dress entrance, so after taking fragrance stick, when fragrance stick rack runs to the fragrance stick dress entrance on the upper, can continue to dress fragrance stick again. Of course, if the movement direction of fragrance stick rack is from above to below circulation in the front end of drying oven body, preferably the fragrance stick taking material mouth is above the fragrance stick dress entrance. In addition to prevent the heat of fragrance stick taking material mouth from dissipating and wasting when not taking material, the fragrance stick taking material mouth is equipped with the taking material door that can open and close. Do not close the taking material door when not taking fragrance stick.

[0007] The fragrance stick dress entrance is preferably a long and flat transverse opening that allows one or more rows of fragrance sticks to be inserted.

[0008] To further improve the efficiency of fragrance stick feeding, the utility model also includes a fragrance stick feeder with a positioning insertion rod. The fragrance stick is fed to the fragrance stick rack through the fragrance stick feeder and the fragrance stick dress entrance. Alternatively, the fragrance stick is fed to the fragrance stick dress entrance through the fragrance stick feeder and aligned with the fragrance stick rack, and then pushed into the fragrance stick rack by a manual or mechanical hand.

[0009] Further, a plurality of screens with arc-shaped insertion slots are stacked on the fragrance stick rack from bottom to top. The arc-shaped insertion slots of the screens are used to place fragrance sticks, and a plurality of air holes are opened in each column of arc-shaped insertion slots. A gap for gas convection is formed between the two adjacent screens. The fragrance stick feeder includes at least one feeding plate corresponding to the arc-shaped insertion slots of the screens. The two sides of the feeding plate are respectively provided with the positioning insertion rods. The positioning insertion rods can be inserted and positioned with the two sides of the screens.

[0010] Further, the outer end of the positioning insertion rod is a bullet-shaped plug, and the inner end is positioned on the feeding plate by a limiting top block. The feeding plate is formed by the downward buckling of the two screens.

[0011] The incense stick loading and unloading displacement controller is a control button located at the front end of the oven body; or a foot pedal controller placed below the front end of the oven body. When loading and unloading incense sticks, the position of the incense stick placement rack near the incense stick loading inlet and the incense stick unloading outlet can be controlled by stepping on the foot pedal controller.

[0012] The advantages of this utility model compared with the prior art are:

[0013] 1. Material drying is achieved directly using a drying oven, and the dehumidification process is unaffected by climate. Furthermore, the oven body is equipped with at least one upper drying channel and at least one lower drying channel, connected by a set of parallel closed-loop conveyor chains. Multiple incense stick holders are sequentially and intermittently mounted on the conveyor chains. The incense stick holders, loaded with the material to be dried, are moved from the front of the oven body to the upper drying channel by the conveyor chains, and then return to the starting position via the rear of the oven body and the lower drying channel, achieving multi-layer circulating drying. Because the incense stick holders remain inside the drying oven throughout the drying process, and the material is directly inserted into the holders through the incense stick inlet at the front, there is no need to remove the holders outside the drying oven to load the material. Therefore, the incense stick holders only need to be heated once inside the drying oven during the drying process, remaining hot thereafter. This effectively reduces the energy consumption of repeatedly heating the holders, resulting in energy savings.

[0014] 2. The front panel of the drying oven body is equipped with an incense stick loading inlet and an incense stick unloading inlet arranged vertically. A loading / unloading incense stick displacement controller is also connected to the control box. This allows for loading and unloading of incense sticks from the same end of the drying oven, eliminating the need for workers to move around, thus improving convenience and efficiency. Furthermore, the incense stick displacement controller allows for real-time adjustment of the height of the incense stick placement racks near the loading and unloading inlets, further enhancing operation and control.

[0015] Third, this utility model can be widely used for the large-scale drying of various materials, especially suitable for the large-scale drying production of incense sticks.
