Technical Field

[0001] The invention relates to the technical field of glycerol hydrogenolysis test devices, in particular to a test device for a glycerol hydrogenolysis catalyst. Background Art

[0002] Glycerol, also known as propylene glycol, is a non-toxic and biodegradable compound with a melting point of 17.8°C and a boiling point of 290.0°C. It is miscible with water and ethanol, but insoluble in benzene, chloroform, carbon tetrachloride, carbon disulfide, petroleum ether and other oils. It is a very important chemical raw material and is widely used in food, medicine, cosmetics, tobacco and other industries.

[0003] Hydrogenolysis refers to the reaction in which part of the oxygen atoms in an organic molecule are replaced by hydrogen atoms. Glycerol hydrogenolysis can produce propylene glycol, which is also an important chemical raw material, mainly used in the production of polyester resins, detergents, cosmetics, plasticizers, surfactants, emulsifiers, etc.

[0004] Glycerol hydrogenolysis refers to the process in which the hydroxyl groups of glycerol break under the action of a catalyst to form propylene glycol. Glycerol hydrogenolysis reactions under different conditions and factors will produce different results. Testing these processes can lead to a more reasonable glycerol hydrogenolysis process and guide the industrial production of propylene glycol. Summary of the invention

[0005] The purpose of the present invention is to provide a testing device for a glycerol hydrogenolysis catalyst. By utilizing an array of raw material storage components connected to a mixing tank, glycerol and different solutions can be added to the mixing tank. By forming a switching transmission connection between the liquid mixing component, the reaction component and the mixing and stirring component through a reaction driving component, the glycerol hydrogenolysis test can be carried out safely and efficiently.

[0006] The objective of the present invention is achieved through such a technical solution. A testing device for a glycerol hydrogenolysis catalyst comprises a frame component, a raw material storage component, a liquid mixing component, a reaction component, a mixing and stirring component and a reaction drive component. The liquid mixing component comprises a mixing tank, a liquid outlet plug and a liquid outlet hose.

[0007] The raw material storage assembly is installed on one side of the frame member, the bottom end of the mixing tank is slidably connected to the inner middle part of the frame member, one end of the liquid outlet hose is connected to the top outlet of the mixing tank, and the other end is connected to the liquid outlet plug, the reaction tower is installed on the other side of the frame member, the flared connecting pipe is connected to one side of the upper end of the reaction tower, and the flared part faces the liquid outlet plug upward, the reaction tower mixing shaft is screwed to the inner middle part of the reaction tower, the inner stirring shaft is screwed to the inner middle part of the mixing tank, the stirring gear is inserted and fixed to the outer top end of the inner stirring shaft, the inner top end of the frame member body is fixed with a fixed rack, and the stirring gear is meshed with the fixed rack;

[0008] The inner horizontal shaft is laterally rotated above the reaction tower, the first rotating bevel gear and the second rotating bevel gear are both rotationally connected in the inner horizontal shaft, and the second rotating bevel gear is transmission connected to the mixing shaft of the reaction tower, the first rotating bevel gear is transmission connected to the mechanism that drives the mixing tank to reciprocate, and a transverse sliding sleeve is also slidably inserted in the middle of the main body of the inner horizontal shaft, and the two ends of the transverse sliding sleeve can respectively form an engagement with the first rotating bevel gear or the second rotating bevel gear, and a transverse connecting seat that can automatically move laterally is provided on the other side of the top end of the frame member, the upper end of the transverse connecting seat is rotationally connected to the transverse sliding sleeve, and the lower end is fixedly connected to the liquid outlet plug.

[0009] The use process of the technical solution of the present invention is as follows:

[0010] The mixing tank is a container for mixing glycerin and solutions. Glycerin and other different solutions can be injected into the mixing tank from various raw material storage components according to the test requirements, so that the glycerin and the solution are fully contacted and mixed. In this process, the automatically movable transverse connecting seat can drive the transverse sliding sleeve to form a transmission connection with the first rotating bevel gear separately. The first rotating bevel gear can drive the mixing tank to move back and forth within a certain range through the transmission mechanism, thereby improving the mixing efficiency.

[0011] And synchronously, it can also drive the stirring gear in a freely rotating state to form a matching transmission with the fixed rack at a fixed position, so that as the mixing tank reciprocates horizontally, the inner stirring shaft fixedly connected to the stirring gear can rotate, thereby stirring the mixture in the mixing tank, further improving the mixing efficiency;

[0012] After the glycerol and the solution are fully contacted and mixed, they can be transferred to the reaction tower for catalytic heating reaction. The liquid outlet plug can be moved by the automatically movable transverse connecting seat, so that the liquid outlet plug can be inserted into the expanded connecting pipe, so that the mixing tank and the reaction tower are connected, and a channel for the mixture in the mixing tank to be transferred to the reaction tower can be formed;

[0013] Synchronously, the transverse sliding sleeve independently forms a transmission connection with the second rotating bevel gear, so that the second rotating bevel gear can drive the rotation of the reaction mixing ring in the reaction tower through the transmission mechanism, and cooperate with the heating of the reaction tower and the addition of hydrogen and catalyst at a certain pressure into the reaction tower to form a glycerol hydrogenolysis reaction. Not only can the glycerol hydrogenolysis reaction after glycerol is mixed with different solutions be tested, but also the glycerol hydrogenolysis reaction under the action of different catalysts can be tested.

[0014] By adopting the above technical solution, the present invention can achieve the following beneficial effects:

[0015] (1) Before glycerol hydrogenolysis, in order to test the effects of different solvents, glycerol can be mixed with any one of the solvents, or glycerol can be mixed with a plurality of solvents. To achieve this purpose, the present invention provides a plurality of raw material storage components connected to the mixing tank, which can be used to store different raw materials, thereby forming test effects with different raw material ratios;

In order to improve the mixing efficiency, the present invention sets the bottom end of the mixing tank in a sliding connection state, and sets an internal stirring shaft inside the mixing tank, and the stirring gear connected to the top end of the internal stirring shaft is meshed with a fixed rack at a fixed position, so that the lateral movement seat can move automatically, so that the lateral movement sleeve is independently connected to the first rotating bevel gear for transmission. After the liquid outlet plug is synchronously disconnected from the flared connecting pipe, the first rotating bevel gear can not only drive the reciprocating lateral movement of the mixing tank through the transmission mechanism, but also drive the passive rotation of the internal stirring shaft located in the mixing tank, thereby achieving the purpose of efficient mixing, and also achieving the purpose of safely cutting off the connection between the mixing tank and the reaction tower during the mixing process;

[0017] (3) The reaction tower is used as a container for catalytic reaction. The liquid outlet plug can be driven to move horizontally by the transverse connecting seat, and the liquid outlet plug is connected with the flared connecting pipe to establish a connecting channel between the mixing tank and the reaction tower, so that the glycerol solution after mixing can enter the reaction tower. After the catalyst and hydrogen are added, a hydrogenolysis reaction can be formed. At the same time, the transverse sliding sleeve can be connected to the second rotating bevel gear transmission separately, so that the reaction tower mixing shaft located in the reaction tower rotates, which can also achieve the purpose of accelerating the catalytic hydrogenolysis reaction process.

[0045] The inner horizontal shaft 604 is laterally screwed on the top of the reaction tower 402 and can rotate automatically. The first rotating bevel gear 605 and the second rotating bevel gear 606 are both rotatably connected in the inner horizontal shaft 604, and the second rotating bevel gear 606 is transmission-connected to the reaction tower mixing shaft 409, and the first rotating bevel gear 605 is transmission-connected to the mechanism that drives the mixing tank 301 to reciprocate.

The other side of the top of the frame member 1 is provided with a transverse connecting seat 613 which can automatically move laterally. The upper end of the transverse connecting seat 613 is screwed to the transverse sliding sleeve 609, and the lower end is fixed to the liquid outlet plug 305. After the transverse connecting seat 613 drives the liquid outlet plug 305 to be inserted into the flared connecting pipe 403 and into place, the transverse sliding sleeve 609 just forms an engagement with the second rotating bevel gear 606 alone.

[0046] Here’s how it works:

[0047] Glycerol hydrogenolysis refers to the process in which glycerol hydroxyl groups are broken to form propylene glycol under the action of a catalyst using glycerol as a raw material.

[0048] The mixing tank 301 is a container for mixing glycerin and solution. According to the test requirements, glycerin and other different solutions can be injected into the mixing tank 301 from each group of raw material storage components 2 so that the glycerin and solution are fully contacted and mixed;

[0049] In this process, the automatically movable transverse connecting seat 613 can drive the transverse sliding sleeve 609 to form a transmission connection with the first rotating bevel gear 605. The first rotating bevel gear 605 can drive the mixing tank 301 to move back and forth within a certain range through the transmission mechanism, thereby improving the mixing efficiency.

[0050] And synchronously, it can also drive the stirring gear 504 in a freely rotating state to form a matching transmission with the fixed rack 505 in a fixed position, so that as the mixing tank 301 reciprocates horizontally, the inner stirring shaft 502 fixedly connected to the stirring gear 504 can rotate, thereby stirring the mixture in the mixing tank 301, and further improving the mixing efficiency;

[0051] After the glycerol is fully contacted and mixed with the solution, it can be transferred to the reaction tower 402 for catalytic heating reaction. The liquid outlet plug 305 can be moved by the automatically movable transverse connecting seat 613, so that the liquid outlet plug 305 can be inserted into the expanded connecting pipe 403, so that the mixing tank 301 and the reaction tower 402 are connected to form a channel for the mixture in the mixing tank 301 to transfer to the reaction tower 402.

[0052] Synchronously, the transverse sliding sleeve 609 forms a transmission connection with the second rotating bevel gear 606 alone, so that the second rotating bevel gear 606 can drive the rotation of the reaction mixing ring 410 in the reaction tower 402 through the transmission mechanism, and cooperate with the heating of the reaction tower 402 and the addition of a certain pressure of hydrogen and a catalyst into the reaction tower 402 to form a glycerol hydrogenolysis reaction.
