Description

Technical Field

[0001] The utility model relates to the technical field of ore drying, in particular to a heat pump drying machine for ore production. Background Art

[0002] Ore drying is an important part of ore processing, and its purpose is to remove moisture from the ore for subsequent processing and use. Traditional ore drying methods mostly use direct heating methods, such as coal, oil or electric heating. These drying methods have some problems, such as high energy consumption, serious environmental pollution, and low drying efficiency.

[0003] In order to improve the efficiency and environmental friendliness of ore drying, heat pump dryers are gradually being used in the field of ore drying. Heat pump dryers use the circulation of refrigerant between the evaporator and the condenser to absorb and release heat to achieve drying. Compared with traditional drying methods, heat pump dryers have the advantages of high energy utilization, environmental protection, and good drying effect.

[0004] However, in the existing heat pump dryers for ore production, the ore is mostly fixed in place during drying, and the drying is uneven and incomplete, which increases the drying time. The fixed placement of the ore makes it difficult to discharge the moisture inside the ore, and the drying efficiency is low. At the same time, the drying degree of the ore surface and the inside is inconsistent, which affects the drying quality. Utility Model Content

[0007] Preferably, the blocking structure includes a support box, a cylinder, a connecting plate, two movable rods and two blocking plates. The support box is arranged on the right side outside the drying box, the cylinder is arranged on the right side outside the support box, and the driving end of the cylinder moves through the right side of the support box, the right side of the connecting plate is connected to the driving end of the cylinder, the two movable rods are connected to the right side of the drying box through a linear sealed bearing, and one end of the two movable rods is connected to the left side of the connecting plate, and the right side of the two blocking plates is connected to the other end of the two movable rods.

[0010] Compared with the prior art, the utility model has the following beneficial effects: the utility model is provided with two sets of inclined slide plates inside the dryer, and arranged in a staggered symmetrical manner, so that the ore can slide and turn effectively during the drying process, and the contact area between the ore and the hot air is greatly increased. This design ensures the uniformity and comprehensiveness of the ore drying. The utility model is also provided with a blocking structure, which can block the ore on the slide plate at regular intervals, thereby increasing the residence time of the ore on the slide plate, and further improving the drying effect.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0016] See also Figure 1-3The utility model provides a heat pump dryer for ore production, comprising a drying box 1, a feed port 2, a discharge door 3, two groups of slide plates 4 and two blocking structures 5. A feed port 2 is arranged on the top of the drying box 1, and the feed port 2 is used for the input of ore. A discharge door 3 is movably connected to the right side of the drying box 1, and the discharge door 3 is used for the discharge of ore. The two groups of slide plates 4 are respectively arranged on the left and right sides of the drying box 1, and the tops of the slide plates 4 are inclined. The number of each group of slide plates 4 is two, and the two slide plates 4 are arranged one up and one down. The two groups of slide plates 4 are staggered and symmetrically arranged. The two groups of slide plates 4 with inclined tops arranged in a staggered and symmetrical manner can make the ore slide and roll during the drying process. Two blocking structures 5 are arranged on the left and right sides of the drying box 1, and the blocking structure 5 is used to block the ore on the slide plates 4 and adjust the residence time of the ore in the drying box 1.

[0017] Specifically, the blocking structure 5 includes a support box 51, a cylinder 52, a connecting plate 53, two movable rods 54 and two blocking plates 55. The support box 51 is arranged on the right side outside the drying box 1, the cylinder 52 is arranged on the right side outside the support box 51, and the driving end of the cylinder 52 moves through the right side of the support box 51, the right side of the connecting plate 53 is connected to the driving end of the cylinder 52, the two movable rods 54 are connected to the right side of the drying box 1 through a linear sealed bearing, and one end of the two movable rods 54 is connected to the left side of the connecting plate 53, and the right side of the two blocking plates 55 is connected to the other end of the two movable rods 54.

[0018] When the blocking structure 5 is working, the driving end of the cylinder 52 will extend, thereby driving the connecting plate 53, the movable rod 54 and the blocking plate 55 to move inward, so that the blocking plate 55 blocks the slide plate 4, increasing the residence time of the ore on each slide plate 4, preventing the ore from sliding off too quickly, and improving the drying effect.

[0019] Specifically, a protrusion 6 is provided on the top of the slide plate 4, and the protrusion 6 can increase the friction between the ore and the inclined plate, slow down the speed of the ore sliding down, and also cause the ore to turn over during the movement.

[0020] Specifically, the bottom of the drying box 1 is inclined, and the lower side thereof is located at the discharge door 3 to facilitate the discharge of the ore.

[0021] Working principle: Ore is put into the drying box 1 from the feed port 2, and passes through two sets of symmetrically displaced slide plates 4. While the ore rolls on the slide plates 4, the ore will turn over due to the inclined setting of the slide plates 4, increasing the contact area between the ore and the hot air, making the drying more uniform. During the drying process, the residence time of the ore in the drying box 1 can be adjusted by controlling the two blocking structures 5, further ensuring the drying effect. Under the action of gravity, the dried ore slides along the inclined surface at the bottom of the drying box 1 to the discharge door 3, and is finally discharged from the discharge door 3.

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
