Description

Technical Field

[0001] This utility model belongs to the field of chemical production technology, and in particular relates to a feeding device for the production of pentaerythritol triallyl ether. Background Technology

[0002] Pentaerythritol triallyl ether, abbreviated as APE, is a colorless and transparent liquid. It is mainly used as a crosslinking agent, such as an acrylic polymer thickener and a superabsorbent resin. Its production is usually achieved by reacting pentaerythritol with allyl halides (such as allyl bromide) in the presence of an alkaline catalyst. In the production process, powdered pentaerythritol needs to be added to a stirred tank to participate in the reaction.

[0003] A search revealed that authorization announcement number CN212189090U, authorized on December 22, 2020, discloses a feeding device for chemical production. The device includes a main body, a discharge port on one side of the main body, a button connected to the front end of the main body, a display screen on one side of the button, a feed inlet connected to the top of the main body, a feed hopper at the top of the feed inlet, and a feeding mechanism connected to one side of the feed hopper. In this invention, the chemical raw materials are placed at the top of a conveyor belt by the feeding mechanism. The partitions separate the chemical raw materials at the top of the conveyor belt, thus controlling the feeding amount. A first motor connected to a power source causes a first roller to rotate under the transmission of the connecting belt, causing the conveyor belt to rotate on the outer walls of the first and second rollers. The second roller, located on one side of the feed hopper, allows the conveyor belt to feed the chemical raw materials into the feed hopper from the top. A fixing plate prevents the chemical raw materials from spilling or scattering at the top.

[0004] Existing technology uses a feeding mechanism to feed raw materials into the hopper. However, in actual use, the vibration generated during the conveying of raw materials and the dispersion of some raw materials when they leave the feeding mechanism and move into the hopper not only waste raw materials but also pollute the operating environment. Furthermore, the fixed landing point of the raw materials after entering the body reduces the stirring efficiency when stirring the raw materials. To address these issues, we provide a feeding device for the production of pentaerythritol triallyl ether to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a feeding device for the production of pentaerythritol triallyl ether. The device is connected to a mixing tank via a conveying pipe, and uses rotating spiral blades to transport the raw materials. The airflow generated by a blower disperses the raw materials falling into the mixing tank. This solves the problems of vibration during raw material transport and the dispersion of some raw materials when they leave the feeding mechanism and move into the feed hopper, which not only wastes raw materials but also pollutes the operating environment. Furthermore, the existing technology has a fixed landing point after the raw materials enter the device, which reduces the mixing efficiency.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a feeding device for the production of pentaerythritol triallyl ether, comprising a base plate, a movable plate slidably connected to the left side of the upper wall of the base plate, a movable motor disposed to the left of the movable plate, a screw fixed on the power output shaft of the movable motor, an electric push rod fixed to the upper wall of the movable plate, a material box disposed above the electric push rod, a conveying pipe fixed to the bottom of the material box, a conveying motor fixed to the left end of the conveying pipe, a rotating rod fixed to the power output shaft of the conveying motor, and a spiral blade fixed to the outside of the rotating rod;

[0008] A mixing tank is provided on the outer side of the right end of the conveying pipe, corresponding to the upper wall of the bottom plate. A stirring motor is fixed at the middle position of the upper wall of the mixing tank. A vertical rod is fixed on the power output shaft of the stirring motor. Stirring rods are fixed at equal intervals from top to bottom on the outer side of the vertical rod. A fan is fixed on the upper side of the peripheral wall of the mixing tank.

[0009] The present invention is further configured such that a support leg is fixed along the edge of the lower wall of the material box, and a mounting plate is fixed at the lower end of the support leg, and the mounting plate is fixedly connected to the electric push rod.

[0010] The present invention is further configured such that guide rods are fixed at the four corner positions of the lower wall of the mounting plate, and guide sleeves are provided on the outer side of the guide rods with clearance fit, and the guide sleeves are fixedly connected to the movable plate.

[0011] The present invention is further configured such that guide strips are symmetrically arranged along the front and rear sides of the movable plate, and the guide strips are fixedly connected to the base plate, and the cross-section of the guide strips is L-shaped.

[0012] The present invention is further configured such that a vertical plate is fixed to the left end of the upper wall of the movable plate, and the screw is threadedly connected to the vertical plate; an end plate is fixed to the left end of the upper wall of the base plate, and the movable motor is fixedly connected to the end plate.

[0013] The present invention is further configured such that a circular hole is provided on the right side of the upper wall of the mixing tank, a filter plate is provided above the circular hole, an installation ring is fixed on the outside of the filter plate corresponding to the upper wall of the mixing tank, an installation cover is threaded to the outside of the installation ring, and an air vent is provided on the surface of the installation cover.

[0014] The present invention is further configured such that a cylinder is provided above the filter plate, an elastic element is fixed to the lower end of the cylinder, a circular plate is fixed to the lower end of the elastic element, a mounting bracket is fixed to the upper end of the cylinder, and the mounting bracket is fixedly connected to the mixing tank, and a drain valve is fixed to the lower end of the peripheral wall of the mixing tank.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model, by setting up an electric push rod, a material box, spiral blades, and a conveying pipe inserted into the mixing tank, lowers the height of the material box by retracting the electric push rod, making it easier to add material into the material box. When the electric push rod extends, it raises the material box and inserts the conveying pipe into the mixing tank. This prevents the material from scattering during the conveying of raw materials and during the process of the material falling into the mixing tank. It solves the problems of vibration during the conveying of raw materials and the scattering of some raw materials when they leave the feeding mechanism and move into the feeding hopper, which not only wastes raw materials but also pollutes the operating environment.

[0017] 2. This utility model incorporates a fan, which generates airflow that blows the raw materials into the mixing tank. This causes the raw materials to disperse irregularly within the mixing tank and come into contact with the liquid inside, resulting in a larger contact area between the raw materials and the liquid. This makes the melting of the raw materials more efficient and prevents them from clumping together due to lack of dissolution. This solves the problem in existing technologies where the raw materials have a fixed landing point after entering the tank, which reduces the stirring efficiency when stirring the raw materials.

Detailed Implementation

[0026] 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.

[0027] Example 1

[0028] Please see Figure 1-3 This utility model is a feeding device for the production of pentaerythritol triallyl ether, including a base plate 5. A movable plate 4 is slidably connected to the left side of the upper wall of the base plate 5. The movement of the movable plate 4 can drive the material box 1 to move. A movable motor 3 is arranged on the left side of the movable plate 4. A screw 301 is fixed on the power output shaft of the movable motor 3. The operation of the movable motor 3 drives the screw 301 to rotate, which can move the movable plate 4. An electric push rod 403 is fixed on the upper wall of the movable plate 4. The material box 1 is arranged above the electric push rod 403. The operation of the electric push rod 403 can drive the material line to move up and down accordingly. A conveying pipe 101 is fixed at the bottom of the material box 1. A conveying motor 2 is fixed at the left end of the conveying pipe 101. A rotating rod 201 is fixed on the power output shaft of the conveying motor 2. A spiral blade 201a is fixed on the outside of the rotating rod 201. The operation of the conveying motor 2 drives the spiral blade 201a to rotate, thereby conveying the raw materials in the material box 1 to the mixing tank 6.

[0029] Specifically, a support leg 102 is fixed along the edge of the lower wall of the material box 1, and a mounting plate 7 is fixed at the lower end of the support leg 102. The mounting plate 7 is fixedly connected to the electric push rod 403. When the electric push rod 403 works, it drives the mounting plate 7 to move, thereby causing the support leg 102 and the material box 1 to move.

[0030] Guide rods 701 are fixed at the four corners of the lower wall of the mounting plate 7. Guide sleeves 401 are provided on the outside of the guide rods 701 with clearance fit. The guide sleeves 401 are fixedly connected to the moving plate 4. The cooperation between the guide rods 701 and the guide sleeves 401 prevents the mounting plate 7 from tilting, so that the mounting plate 7 can move up and down stably.

[0031] Guide strips 502 are symmetrically arranged along the front and rear sides of the movable plate 4, and the guide strips 502 are fixedly connected to the base plate 5. The cross-section of the guide strips 502 is L-shaped. The guide strips 502 are used to make the movable plate 4 move left and right in the horizontal direction to prevent the movable plate 4 from tilting.

[0032] A vertical plate 402 is fixed to the left end of the upper wall of the movable plate 4, and the screw 301 is threadedly connected to the vertical plate 402. An end plate 501 is fixed to the left end of the upper wall of the bottom plate 5, and the movable motor 3 is fixedly connected to the end plate 501. With the above configuration, when the screw 301 rotates, it drives the vertical plate 402 to move, thereby causing the movable plate 4 to move.

[0033] The operation process of this embodiment is as follows: When adding raw materials to the inside of the material box 1, the electric push rod 403 is extended to drive the conveying pipe 101 to separate from the mixing tank 6. Then, the moving motor 3 is operated to drive the screw 301 to rotate and move the moving plate 4 to the left, which can drive the material box 1 to move to the left to a suitable position. At this time, the electric push rod 403 is retracted to drive the material box 1 to move down so that the material box 1 is at a suitable height and the raw materials are poured into the material box 1.

[0034] Next, after adding an appropriate amount of raw materials into the material box 1, extend the electric push rod 403 to drive the material box 1 to rise until the height of the conveying pipe 101 is higher than the height of the upper wall of the mixing tank 6. At this time, the moving motor 3 is activated to drive the screw 301 to rotate. Under the action of the vertical plate 402, the material box 1 moves to the right to a suitable position. Then, retract the electric push rod 403 until the end of the conveying pipe 101 is inserted into the mixing tank 6.

[0035] Then, the conveyor motor 2 is activated to drive the rotating rod 201 to rotate, causing the spiral blades 201a to rotate, and the raw materials inside the material box 1 are uniformly conveyed to the inside of the mixing tank 6.

[0036] Example 2

[0037] Please see Figure 1 , 24 and 5 are the second embodiment of this utility model. This embodiment is based on the previous embodiment, but differs from the first embodiment in that: a stirring tank 6 is provided on the outer side of the right end of the conveying pipe 101 corresponding to the upper wall of the bottom plate 5. A stirring motor 8 is fixed at the middle position of the upper wall of the stirring tank 6. A vertical rod 801 is fixed on the power output shaft of the stirring motor 8. Stirring rods 801a are fixed at equal intervals from top to bottom on the outer side of the vertical rod 801. The stirring motor 8 drives the vertical rod 801 to rotate, causing the stirring rods 801a to rotate, thereby stirring the raw materials inside the stirring tank 6. A fan 602 is fixed on the upper side of the periphery of the stirring tank 6. The fan 602 generates airflow that acts on the raw materials that are about to be mixed with the liquid inside the stirring tank 6, so that the raw materials are fully distributed inside the stirring tank 6, expanding the distribution area of ​​the raw materials and making the dissolution more complete.

[0038] Specifically, a circular hole is provided on the right side of the upper wall of the mixing tank 6, and a filter plate 604 is provided above the circular hole. An installation ring 603 is fixed to the outside of the filter plate 604 corresponding to the upper wall of the mixing tank 6. An installation cover 603a is threaded to the outside of the installation ring 603. An air outlet is provided on the surface of the installation cover 603a. With the above configuration, the blower 602 draws in air from the outside and enters the mixing tank 6 to act on the raw materials. The airflow will eventually pass through the filter plate 604 and be discharged to the outside environment. The filter plate 604 filters the raw materials and prevents the raw materials from drifting to the outside of the mixing tank 6.

[0039] A cylinder 9 is installed above the filter plate 604. An elastic element 901 is fixed to the lower end of the cylinder 9. The elastic element 901 allows the circular plate 901a to move relative to the movable end of the cylinder 9, which can prevent the circular plate 901a from acting on the filter plate 604 with a large force and causing damage to the filter plate 604. The circular plate 901a is fixed to the lower end of the elastic element 901. A mounting bracket 902 is fixed to the upper end of the cylinder 9, and the mounting bracket 902 is fixedly connected to the mixing tank 6. A drain valve 601 is fixed to the lower end of the peripheral wall of the mixing tank 6. The cylinder 9 intermittently drives the elastic element 901 and the circular plate 901a to descend, and the circular plate 901a strikes the filter plate 604 to prevent the raw material from clogging the filter plate 604. The mixed liquid is discharged through the drain valve 601.

[0040] Furthermore, the upper wall of the mixing tank 6 is also provided with a feed pipe for adding reaction liquid, and the feed pipe is externally threaded to a pipe cap;

[0041] The remaining structure is the same as in Example 1;

[0042] The operation process of this embodiment is as follows: when the raw material enters the mixing tank 6 through the conveying pipe 101, the stirring motor 8 drives the vertical rod 801 to rotate, so that the stirring rod 801a rotates to stir the liquid inside the mixing tank 6. At the same time, the blower 602 works to generate airflow that acts on the falling raw material, so that the raw material is blown away and evenly distributed in the mixing tank 6, and then naturally settles on the surface of the liquid and melts with the liquid inside the mixing tank 6. The airflow entering the mixing tank 6 passes through the round hole, the air outlet and the filter plate 604 and is discharged to the outside of the mixing tank 6.

[0043] During the stirring process, the lower end of the cylinder 9 reciprocates intermittently, causing the elastic element 901 and the circular plate 901a to move. The circular plate 901a acts on the filter plate 604 to cause the raw material powder filtered by the filter plate 604 to separate from the filter plate 604 to prevent clogging.

[0044] In addition, all electrical appliances in the feeding device for the production of pentaerythritol triallyl ether can be controlled by a microcontroller in the controller. The electrical appliances are electrically connected to the microcontroller in the controller via conductive wires, and the microcontroller in the controller is electrically connected to an external power supply via conductive wires. At the same time, both the electrical appliances and the controller are existing technologies, and their models are not limited here. Furthermore, the feeding device for the production of pentaerythritol triallyl ether is also equipped with a heating component for heating the mixing tank 6 to maintain the raw materials at a suitable temperature. The heating component is existing technology and is not shown in the figure.
