DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example 1

[0040] Reference Figure 1-10 , a raw material rake dryer for synthesis of methyl thiophanate, comprising a drying tank 2, the drying tank 2 is rotatably mounted on a support frame 1, and a first rotating motor 4 is fixed on the support frame 1, the first rotating motor 4 is equipped with a first motor reducer 401, the output power of the first rotating motor 4 is decelerated by the first motor reducer 401 to drive the drying tank 2 to rotate slowly as a whole, a stirring shaft 5 is rotatably mounted inside the drying tank 2, a plurality of stirring branches 6 are fixed on the outer side of the stirring shaft 5, the stirring branches 6 are grouped in two, and the plurality of stirring branches 6 are equidistantly distributed in the axial direction of the stirring shaft 5, and a hot air inlet and outlet mechanism is provided on the drying tank 2;

[0041] A material inlet and outlet port 201 is provided on one side of the drying tank 2, and an arc-shaped baffle plate 202 is provided at the position of the material inlet and outlet port 201. The arc-shaped baffle plate 202 is driven by an opening and closing driving mechanism to move and open and close the material inlet and outlet port 201.

[0042] The drying tank 2 can be driven to rotate by the first rotating motor 4. When the inlet and outlet 201 faces upward, the wet material to be dried can be added to the drying tank 2 through the inlet and outlet 201. The arc baffle 202 can be driven to move to open and close the inlet and outlet 201 through the opening and closing driving mechanism. After the material addition is completed, the drying tank 2 is driven by the first rotating motor 4 to rotate 180 degrees so that the inlet and outlet 201 faces downward and the inlet and outlet 201 is closed. At this time, hot air is introduced into the drying tank 2 through the hot air inlet and outlet mechanism, and the stirring of the stirring shaft 5 is used to accelerate the drying. When the drying is completed, the inlet and outlet 201 is opened to discharge the dry material. The stirring shaft 5 is driven by the second rotating motor 3 installed on the drying tank 2, and the second rotating motor 3 is equipped with a second motor reducer 301.

[0043] Example 2

[0044] Reference Figure 1-10 The difference between this embodiment and the first embodiment is that the opening and closing driving mechanism includes an elastic telescopic guide rod 203, the elastic telescopic guide rod 203 is fixed on the outer wall of the drying tank 2, and the curvature of the elastic telescopic guide rod 203 corresponds to the curvature of the outer wall of the drying tank 2, and the movable end of the elastic telescopic guide rod 203 is fixed to the arc baffle 202;

[0045] The elastic force of the elastic telescopic guide rod 203 can push the arc baffle 202 to move along the outer wall of the drying tank 2, and when the elastic telescopic guide rod 203 is not compressed by external force, the arc baffle 202 just opens the inlet and outlet port 201. When the dry material needs to be discharged, the arc baffle 202 can be manually pushed to move, so that the elastic telescopic guide rod 203 is compressed and shortened, and the inlet and outlet port 201 can be opened.

[0046] The arc-shaped baffle 202 is fixed with an arc-shaped guide bar 204, and one end of the arc-shaped guide bar 204 away from the arc-shaped baffle 202 is moved on the outer wall of the drying tank 2 through an arc-shaped guide rail 205, and a first arc-shaped rack 206 is also fixed on the arc-shaped guide bar 204;

[0047] The coordination of the arc-shaped guide bar 204 and the arc-shaped guide rail 205 ensures the stability of the installation of the arc-shaped baffle 202. A horizontally arranged transmission shaft 207 is rotatably installed on the outer wall of the drying tank 2. A first gear 208 is fixed on the transmission shaft 207. The first gear 208 is meshed with the first arc-shaped rack 206. A second arc-shaped rack 210 is fixed on the support frame 1 through a connecting rod. The second arc-shaped rack 210 is located obliquely above the drying tank 2, and a second gear 209 is fixed on the outside of the transmission shaft 207 and the position of the second arc-shaped rack 210.

[0048] Due to the existence of the second arc-shaped rack 210, during the feeding stage, as the drying tank 2 rotates, the inlet and outlet port 201 gradually moves upward, the second gear 209 will mesh with the second arc-shaped rack 210, and the second gear 209 will move along the second arc-shaped rack 210, and mesh with each other and drive the transmission shaft 207 to rotate. When the transmission shaft 207 rotates, the first gear 208 can mesh with the first arc-shaped rack 206 to drive the arc-shaped baffle 202 to move, so as to achieve the purpose of automatically driving the arc-shaped baffle 202 to move and open the inlet and outlet port 201. When the inlet and outlet port 201 is completely upward, the inlet and outlet port 201 is fully opened. After the feeding is completed, as the drying tank 2 rotates, when the second gear 209 is disengaged from the second arc-shaped rack 210, the arc-shaped baffle 202 will automatically move to block the inlet and outlet port 201 due to the elastic effect of the elastic telescopic guide rod 203, thereby ensuring the airtightness of the drying process.

[0049] Example 3

[0050] Reference Figure 1-10 The difference between this embodiment and embodiment 1 is that the hot air inlet and outlet mechanism includes an air inlet pipe 8 and an air outlet, the air outlet is opened on the outer wall of the drying tank 2 away from the inlet and outlet 201, and a filter is provided in the air outlet;

[0051] The hot air is introduced into the drying tank 2 through the air inlet pipe 8 and then discharged through the air outlet, thereby heating and drying the wet material. The presence of the filter can prevent the material from being carried out by the hot air, prevent material waste, and keep the production environment clean.

[0052] The stirring shaft 5 is hollow inside, and the air inlet pipe 8 is connected to the stirring shaft 5 through a rotary joint 801. The stirring branch 6 is hollow inside and connected to the stirring shaft 5. The stirring branch 6 is provided with a plurality of exhaust ports 601.

[0053] The hot air enters the stirring shaft 5 through the air inlet pipe 8, and is then discharged through the exhaust port 601 on the stirring branch 6, so as to evenly distribute the gas. The hot air is evenly ejected and acts on the surface of the raw material, thereby improving the drying efficiency. An intermittent blocking rod 7 is fixed on the air inlet pipe 8, and the intermittent blocking rod 7 extends into the stirring shaft 5. An arc-shaped blocking plate 701 is fixed on the intermittent blocking rod 7 at a position corresponding to the stirring branch 6. The arc-shaped blocking plate 701 is used to block the connecting hole 501 between the stirring branch 6 and the stirring shaft 5.

[0054] Due to the presence of the intermittent sealing rod 7 and the arc-shaped sealing plate 701, when the stirring shaft 5 rotates, the arc-shaped sealing plate 701 will move relative to the inner wall of the stirring shaft 5, so that the connecting hole 501 between the stirring branch 6 and the stirring shaft 5 can be intermittently blocked, thereby achieving the intermittent injection effect of hot air, which helps to blow away the wet material, improve the uniform heating effect of the wet material, and enhance the drying effect.

[0055] A scraper 602 is fixed to the side of the stirring branch 6 away from the stirring shaft 5, and the scraper 602 contacts the inner wall of the drying tank 2. The scraper 602 can scrape the inner wall of the drying tank 2 to effectively prevent the raw materials from adhering to the tank wall and ensure thorough drying.
