Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, specifically a feeding device for a chemical reaction vessel. Background Technology

[0002] In a broad sense, a reaction vessel is a container that carries out physical or chemical reactions. Through structural design and parameter configuration, it achieves the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process. Reactors are widely used in petroleum, chemical, rubber, pesticide, dye, pharmaceutical, and food industries. They are pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation. Examples include reactors, reaction vessels, decomposition vessels, and polymerization kettles.

[0003] The dust-free feeding station is one of the commonly used devices for feeding raw materials into chemical reaction vessels. Its operating procedures are as follows:

[0004] The operator places the material bag on the support and pushes it into the grid. Then, the operator manually cuts open the material bag and tilts and shakes it to empty it. The material falls into the hopper by gravity and can be connected to the conveying unit through the bottom conveying pipe to transport the material to the feed port of the chemical reactor, realizing the feeding operation. At the same time, the built-in induced draft dust collector can collect the dust generated during the emptying of the material bag, effectively avoiding dust and smoke.

[0005] In actual operation, when the chemical raw material bag is long, the material inside cannot be poured out all at once. The operator needs to lift the tail of the chemical raw material bag upwards to tilt it vertically so that the material can fall more quickly. This operation requires a lot of strength to complete, and frequent operation will increase the workload of the operator. Therefore, in order to reduce the workload of the operator, a chemical reactor feeding device is provided. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-3 In this embodiment of the present invention, a chemical reactor feeding device includes a feeding station assembly 1 consisting of a feeding hopper 101, a feeding platform 102, a front cover plate 103, a filter 104, and an induced draft fan 105. The feeding platform 102 is fixed to the front end of the feeding hopper 101 and aligned with the feeding port. The front cover plate 103 is movably connected to the top of the feeding port of the feeding hopper 101 via a hinge and is connected to the side of the outer wall of the feeding hopper 101 via a hydraulic support rod. The filter 104 is installed on the top of the inner wall of the feeding hopper 101. The induced draft fan 105 is fixed to the top of the outer wall of the feeding hopper 101 and communicates with the inner cavity of the filter 104. An auxiliary pouring assembly 2 is provided on the inner and outer sides of the feeding hopper 101. The auxiliary pouring assembly 2 is used to provide support and a flipping drive for the material bag.

[0028] The auxiliary material pouring component 2 includes a support unit and a tilting drive unit;

[0029] The support unit provides support for the tipping and unloading of the material bag;

[0030] The flipping drive unit is used to realize the flipping operation of the support unit to simulate the operation of manually lifting the bag and tilting it upright;

[0031] The support unit includes a bearing base 201, a tilting shaft 202, a connector 203, and a side-concave grid frame 204;

[0032] The bearing base 201 is symmetrically fixed on both sides of the outer wall of the feeding bin 101. The tilting shaft 202 is distributed inside the feeding bin 101 and passes through the feeding bin 101 and the two bearing bases 201, and is rotatably connected to the bearing base 201 and the feeding bin 101.

[0033] The connector 203 and the side concave grid frame 204 are located inside the feeding hopper 101, and the connector 203 is fixed to the outside of the tilting shaft 202, while the side concave grid frame 204 is fixed to the front end of the connector 203.

[0034] The bottom grid portion of the concave grid frame 204 is inclined toward the feeding port of the feeding hopper 101, and the concave grid frame 204 is used to provide support for the tipping and dumping of the material bag;

[0035] The tilting drive unit includes a tilting arm 205, a pneumatic push rod 206, and a connecting pin 207;

[0036] The tilting arm 205 is symmetrically fixed on both sides of the tilting shaft 202. The tail end of the housing of the pneumatic push rod 206 is rotatably connected to the feeding bin 101 through the connecting pin 207. The connecting pin 207 is fixedly connected to the outer wall side of the feeding bin 101.

[0037] The output end of the pneumatic push rod 206 is rotatably connected to the end of the flipping arm 205 away from the flipping shaft 202. The pneumatic push rod 206 drives the flipping arm 205 to realize the flipping operation of the support unit. The side concave grid frame 204 rotates upward to simulate manually lifting the bag and tilting it upright.

[0038] In this embodiment, it should be noted that: the hydraulic support rod provides support for the open state of the front cover plate 103; the operation of the induced draft fan 105 generates suction inside the feeding hopper 101, thereby sucking up the dust generated during the unloading process; the filter 104 is used to filter and intercept the dust; the bottom of the feeding hopper 101 has an open structure; and when the device is in use, the bottom of the feeding hopper 101 is connected to the feed port of the reactor through a conveying device. The conveying device can be a screw conveyor or a vacuum feeder, which are all existing mature technologies and equipment, so they will not be described in detail here.

[0039] The procedure for unloading materials is as follows:

[0040] The material bag is manually moved to the loading platform 102, then the material bag is ripped and pushed into the concave grid frame 204. At this time, the material bag is tilted downwards. The material in the material bag falls out from the ripped part of the material bag under its own weight and falls into the loading bin 101 through the gap on the concave grid frame 204.

[0041] At the same time, the pneumatic push rod 206 can be activated (it should be noted that the pneumatic push rod 206 is controlled by a pedal switch to start and stop). The output end of the pneumatic push rod 206 extends to push the tilting arm 205. The tilting arm 205 drives the tilting shaft 202, the connecting piece 203, and the side concave grid frame 204 to rotate as a whole. In this way, the material bag can be lifted to a tilted and upright position, so that the tilt angle of the material bag is greater, thereby allowing the material in the material bag to slide down faster and all the material in the material bag can be poured out (it should be noted that during this process, the operator's hands hold the tail end of the material bag to ensure the stability of the material bag in a large-angle tilted and upright position).

[0042] The above operation can simulate the manual lifting of the material bag and tilting it vertically, achieving efficient material feeding and effectively reducing the workload of workers.

[0043] Please refer to this carefully. Figures 1-3 The length of the top grid part of the concave grid frame 204 is less than the length of the bottom grid part, and the front end of the top grid part has an upward curved structure.

[0044] In this embodiment: This structure allows the top grid portion of the concave grid frame 204 to be at a certain distance from the feeding port of the feeding hopper 101, so as not to affect the operation of the material bag entering the concave grid frame 204. It should also be noted that when the concave grid frame 204 is flipped to the maximum angle state, the top grid portion of the concave grid frame 204 does not contact the filter 104.

[0045] Please refer to this carefully. Figure 2 The inner front end face of the feeding hopper 101 is fixed with a 7-shaped support frame 106 at the bottom of the feeding port, and the bottom grid part of the side concave grid frame 204 overlaps the upper surface of the 7-shaped support frame 106.

[0046] In this embodiment: during the process of pushing the bag into the concave grid frame 204, the bag has a large impact force on the concave grid frame 204, and its 7-shaped support frame 106 can provide support for the concave grid frame 204, so that the concave grid frame 204 maintains good stability.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
