Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a mixing device for polyethylene raw materials. Background Art

[0002] A raw material mixing device refers to a device used to evenly mix two or more solid, liquid or solid-liquid raw materials in many industries such as chemical, pharmaceutical, food processing, building materials, plastics, and coatings.

[0003] These devices are designed to ensure adequate contact and uniform distribution of raw materials in order to achieve ideal physical or chemical reaction conditions and improve the quality of the final product.

[0004] In order to facilitate the discharge of materials, the existing raw material mixing device is provided with a valve that can be opened and closed at the bottom of the mixing device box. It can be seen that the raw materials in the box may be blocked at the valve, resulting in the inability to discharge materials normally, and its stability is relatively poor. Summary of the invention

[0005] The purpose of the utility model is to provide a polyethylene raw material mixing device with high stability and compact structure in view of the above problems existing in the prior art.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A mixing device for polyethylene raw materials, comprising a frame and a box body, wherein the interior of the box body is a cavity and the upper end is open, the box body is fixedly connected to the frame, and the bottom of the box body has a discharge port, characterized in that the discharge port is located in the middle of the frame, and the discharge port has an opening and closing mechanism that can open and close the discharge port, and also includes a ladder and a base, the ladder is fixedly connected to the outside of the box body, and the base is fixedly connected to the bottom of the frame and the base can contact the ground with a large area.

[0008] The polyethylene raw material mixing device creatively arranges an opening and closing mechanism at the material outlet. In the initial state, the opening and closing mechanism closes the material outlet. At this time, the polyethylene raw material can be stably and fully mixed in the box.

[0009] Of course, when the raw materials are mixed, the stirrer is extended into the box, and the rotating stirrer performs a stable mixing operation on the raw materials in the box. Since the stirrer and the mixing device are two independent devices, the specific technical features of the stirrer are not repeated in this technical solution.

[0010] Since the box in this device is relatively large in size, the operator can easily climb to the bottom of the box through a ladder to observe the mixing operation inside the box.

[0011] At the same time, since the base can contact the ground over a large area, the entire mixing device can be stably placed on the ground.

[0012] In the above-mentioned mixing device for polyethylene raw materials, the opening and closing mechanism includes baffle one, baffle two and a cylinder. The above-mentioned baffle one and baffle two are hinged on the outside of the box body, the cylinder body of the above-mentioned cylinder is hinged on baffle two, and the piston rod of the cylinder is hinged on baffle one. In the initial state, the lower part of the baffle and the lower part of the baffle two are abutted against each other and block the discharge port. After the cylinder is actuated, the baffle one and the baffle two can move away from each other, and the lower part of the baffle and the lower part of the baffle two can move away from the discharge port.

[0013] In the initial state, baffle plate 1 and baffle plate 2 are close to each other, and at this time, baffle plate 1 and baffle plate 2 close the discharge port. After the cylinder is actuated, baffle plate 1 and baffle plate 2 can be moved away from each other, so that the discharge port at the bottom of the box body is stably opened.

[0014] In the above-mentioned polyethylene raw material mixing device, the lower end of the discharge port is arc-shaped, the lower part of the above-mentioned baffle has an arc-shaped sealing part 1 that matches the discharge port, and the lower part of the above-mentioned baffle 2 has an arc-shaped sealing part 2 that matches the discharge port.

[0015] The first sealing part and the second sealing part are both matched with the arc-shaped lower end of the discharge port. Such a structure can effectively improve the airtightness of the discharge port when it is closed.

[0016] In the above-mentioned polyethylene raw material mixing device, the baffle plate 1 is U-shaped, and the two ends of the U-shape of the baffle plate 1 are respectively hinged at two sides of the box body.

[0017] In the above-mentioned polyethylene raw material mixing device, the baffle plate 2 is U-shaped, and the two ends of the U-shape of the baffle plate 1 are respectively hinged at two sides of the box body.

[0018] The above structure can stably hinge the baffle plate 1 and the baffle plate 2 on the box body.

[0019] In the above-mentioned polyethylene raw material mixing device, the baffle plate 1 has a hinged portion 1 protruding outward in the middle, the baffle plate 2 has a hinged portion 2 protruding outward in the middle, the cylinder body of the above-mentioned cylinder is hinged at the hinged portion 2, and the piston rod of the cylinder is hinged at the hinged portion 1.

[0020] The setting of the first articulated part provides sufficient position for the piston rod of the air cylinder to be articulated, and the setting of the second articulated part provides sufficient position for the cylinder body of the air cylinder to be articulated.

[0021] In the above-mentioned polyethylene raw material mixing device, the upper end of the baffle plate 1 is fixedly connected to the transmission gear 1, and the upper end of the baffle plate 2 is fixedly connected to the transmission gear 2, and the transmission gear 1 is meshed with the transmission gear 2.

[0022] The transmission gear 1 is meshed with the transmission gear 2, and such a structure enables the baffle 1 and the baffle 2 to swing synchronously around their hinges.

[0023] In the above-mentioned polyethylene raw material mixing device, a cover shell with a hollow interior and an opening at the bottom is fixedly connected to the outer side of the box body, and the above-mentioned transmission gear 1 and transmission gear 2 are both located in the cover shell.

[0024] The cover shell covers the transmission gear 1 and the transmission gear 2, and can prevent rainwater or debris from entering the meshing position of the transmission gear 1 and the transmission gear 2.

[0025] In the above-mentioned polyethylene raw material mixing device, a transversely arranged reinforcing rod is fixedly connected to the outer side of the box body, the lower end of the above-mentioned ladder is fixedly connected to the reinforcing rod, and the above-mentioned cover shell is fixedly connected between the reinforcing rod and the box body.

[0026] The reinforcement rod not only improves the strength of the box body, but also enables the cover shell to be stably fixed between the reinforcement rod and the box body.

[0027] Compared with the prior art, the polyethylene raw material mixing device has relatively high operation stability because the discharge port can be stably opened and closed.

[0028] At the same time, baffle plate 1 and baffle plate 2 in the opening and closing mechanism are in contact with the bottom surface of the discharge port, which not only further improves its stability, but also allows the opening and closing mechanism to open and close smoothly without the possibility of blockage by raw materials.

[0029] In addition, the opening and closing mechanism and the cover shell are both arranged at the bottom of the box body, so less space is occupied, the overall structure is relatively compact, and it has high practical value. BRIEF DESCRIPTION OF THE DRAWINGS
