Description

Technical Field

[0001] This utility model relates to the field of dryer technology, specifically to a double cone dryer. Background Technology

[0002] The double cone dryer is a widely used drying equipment in industrial production, mainly used for drying various granular and powdery materials. Its unique double cone structure design ensures uniform heating of the material during the drying process, thereby improving drying efficiency and product quality. However, in existing double cone dryers, materials easily agglomerate within the drying tank during the drying process. This agglomeration affects the drying effect and the quality of the final product. Current methods mostly employ a stirring mechanism to crush the agglomerated material. However, placing the stirring mechanism inside the drying tank not only results in poor material agitation and crushing but also requires a separate drive unit, increasing the complexity of the equipment. Furthermore, maintenance and repair of the stirring mechanism within the drying tank are inconvenient when it malfunctions. Therefore, we propose a new double cone dryer. Utility Model Content

[0003] The purpose of this invention is to provide a double cone dryer to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a double cone dryer, comprising a dryer body, a drying tank assembled inside the dryer body, assembly mechanisms symmetrically distributed in upper and lower positions assembled inside the drying tank, and a crushing mechanism assembled between the assembly mechanisms;

[0005] The crushing mechanism includes an upper frame and a lower frame, with a support plate fixedly connected between the upper frame and the lower frame. Cutting blades are embedded in the upper frame and the lower frame, and connecting plates are fixedly connected to the side walls of the upper frame and the lower frame, respectively. Connecting shafts are fixedly connected to the upper and lower side walls of the connecting plates, respectively.

[0006] Preferably, the connecting plate is evenly distributed circumferentially at the center of the upper and lower frames.

[0007] Preferably, the number of connecting shafts on each side wall of the connecting plate is at least two, and a spring is sleeved on the outer side wall of the connecting shaft.

[0008] Preferably, the assembly mechanism includes an upper assembly plate and a lower assembly plate, which are fixedly assembled from top to bottom on the inner cavity sidewall of the drying tank. The connecting plate is located between the upper assembly plate and the lower assembly plate, and the sidewalls of the upper assembly plate and the lower assembly plate are provided with connecting holes.

[0009] Preferably, the upper assembly plate and the lower assembly plate are evenly distributed around the center of the drying tank in a circular pattern, and the number and position of the upper assembly plate, the lower assembly plate and the connecting plate are respectively corresponding.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: Compared with the traditional double cone dryer, this utility model adopts a crushing mechanism instead of the traditional stirring mechanism and is set in the drying tank. During the process of drying the material by rotating the drying tank, the crushing mechanism can effectively crush the material that has agglomerated into lumps, avoiding the material from agglomerating in the drying tank and thus affecting the drying effect. At the same time, the crushing mechanism is assembled in the drying tank through the assembly mechanism, eliminating the need for a corresponding drive unit, thus achieving the crushing effect of the crushing mechanism on the material, and making maintenance and repair easier.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4This utility model provides a technical solution: a double cone dryer, including a dryer body 1. The dryer body 1 is a common double cone dryer in the prior art, mainly used for drying powdery materials. A drying tank 2 is assembled inside the dryer body 1. The two ends of the drying tank 2 are respectively provided with a feed inlet and a discharge outlet, which are sealed with end caps. The two ends of the drying tank 2 are respectively provided with connection ports. One connection port is used to connect to an external vacuum pipeline. The vacuum pipeline is used to extract the air inside the drying tank 2 to make the drying tank 2 a vacuum state. The other end is used to connect to a circulation pipeline. Hot fluid is introduced into the partition of the drying tank 2 through the circulation pipeline to heat the drying tank 2, thereby drying the material inside.

[0018] The inner wall of the drying tank 2 is equipped with symmetrically distributed assembly mechanisms 3. A crushing mechanism 4 is installed between the assembly mechanisms 3. When the drying tank 2 is rotating and drying, the crushing mechanism 4 crushes the material that has clumped in the drying tank 2 by moving between the assembly mechanisms 3. This prevents the material from clumping during the drying process and avoids affecting the subsequent drying and the finished product.

[0019] like Figure 2 As shown, the assembly mechanism 3 includes an upper assembly plate 31 and a lower assembly plate 32. The upper assembly plate 31 and the lower assembly plate 32 are fixedly connected to the inner cavity side wall of the drying tank 2 from top to bottom. The upper assembly plate 31 and the lower assembly plate 32 are respectively provided with corresponding connecting holes 33. The upper assembly plate 31 and the lower assembly plate 32 are evenly distributed in a circle around the center of the drying tank 2.

[0020] like Figure 2 and Figure 3 As shown, the pulverizing mechanism 4 includes an upper frame 41 and a lower frame 42. A support plate 43 is fixedly connected between the upper frame 41 and the lower frame 42. The support plate 43 is evenly distributed in a circle around the center of the upper frame 41 and the lower frame 42. The support plate 43 supports and fixes the upper frame 41 and the lower frame 42. The distribution position of the support plate 43 is staggered with the connection of the vacuum pipeline to avoid obstructing the adsorption position of the vacuum pipeline and affecting the adsorption effect of the vacuum pipeline on the air in the drying tank 2.

[0021] Both the upper frame 41 and the lower frame 42 are fitted with staggered cutting blades 44. As the drying tank 2 rotates, the material collides with the cutting blades 44, and the cutting blades 44 crush the material that has agglomerated into lumps.

[0022] Connecting plates 45 are fixedly connected to the side walls of the upper frame 41 and the lower frame 42 respectively. The number of connecting plates 45 matches the number of upper assembly plates 31 and lower assembly plates 32. The connecting plates 45 are assembled between the upper assembly plates 31 and the lower assembly plates 32. Connecting shafts 46 with through connecting holes 33 are fixedly connected to the upper and lower side walls of the connecting plates 45 respectively. The number of connecting shafts 46 on each side of each connecting plate 45 is at least two. The number and position of the connecting holes 33 correspond to the number and position of the connecting shafts 46. By increasing the number of connecting shafts 46, the stability of the connection between the upper assembly plates 31, the lower assembly plates 32 and the connecting plates 45 can be increased, so that the upper assembly plates 31 and the lower assembly plates 32 can better limit the movement stroke of the connecting plates 45.

[0023] A spring 47 is sleeved on the outer wall of the connecting shaft 46. The spring 47 supports the connecting plate 45, so that the connecting plate 45 is located in the middle position between the upper assembly plate 31 and the lower assembly plate 32. During the drying process, as the drying tank 2 is rotated, the connecting plate 45 can squeeze the spring 47, so that the upper frame 41 and the lower frame 42 repeatedly move up and down in a certain range within the inner cavity of the drying tank 2. The upper frame 41 and the lower frame 42 after the action can increase the force when the cutting blade 44 contacts the material, and enhance the crushing effect of the cutting blade 44 on the agglomerated material.

[0024] Working principle: During use, the material to be dried is added into the drying tank 2, and then the drying tank 2 is sealed. The vacuum pipeline sucks out the air from the drying tank 2, making the drying tank 2 a vacuum state. Then, the circulation pipeline introduces hot fluid into the drying tank 2 to heat the drying tank 2. As the drying tank 2 rotates, the material inside is dried. During the drying process, the material passes through the cutting blades 44 in the upper frame 41 and lower frame 42 in sequence, which can effectively prevent the material from agglomerating into lumps during the drying process. At the same time, the up and down movement of the upper frame 41 and lower frame 42 within a certain range further improves the crushing effect of the cutting blades 44 on the agglomerated material.
