Description

Technical Field

[0001] The utility model relates to the technical field of chemical production, in particular to an automatic packaging and loading device for ammonium sulfate. Background Art

[0002] The ammonium sulfate production unit is an important intermediate link in the entire production process of caprolactam. Its main task is to neutralize the sulfuric acid in the rearrangement liquid from the amine oximation unit with ammonia water. The resulting product ammonium sulfate is sent to the packaging unit for packaging after centrifugal separation and drying.

[0003] At present, the annual sales volume of bulk materials in the market is about 150,000 tons, which are mostly packaged and exported. According to market research, packaged ammonium sulfate products need to be cut into bags before use, which increases the cost of product use. At the same time, product packaging also consumes the manpower and material resources of the production enterprises, resulting in increased product costs.

[0004] When bulk materials are directly loaded onto trucks, the materials will fly and affect the environment during the loading process. At the same time, the loading volume cannot be accurately controlled during bulk loading. Overloading will lead to vehicle overload or even material overflow, while underloading will lead to increased transportation costs. Therefore, an automatic packaging and loading device for ammonium sulfate is needed to meet the demand of downstream customers for ammonium sulfate bulk materials. Summary of the Invention

[0005] In order to expand the downstream market and meet the needs of more downstream users, the utility model provides an automatic packaging and loading device for ammonium sulfate, which can directly load the bulk materials into trucks for sale while meeting the requirements of ammonium sulfate packaging for small bags for sale. It solves the problems of high packaging cost of ammonium sulfate products, inability to directly load the bulk materials into trucks and inability to fully utilize the value of the products in the current mode of selling only packaged products.

[0006] The utility model is implemented by the following technical solutions:

[0007] An automatic packaging and loading device for ammonium sulfate comprises a weighing hopper, an output pipe at the bottom of the weighing hopper being connected to a first branch and a second branch, the first branch being connected to a quantitative packaging machine, the bottom of the quantitative packaging machine being connected to a conveyor belt; the second branch being connected to an input end of a material guide pipe, a plug valve being provided in the middle of the material guide pipe, an output end of the material guide pipe being connected to a dust hood, the top of the dust hood being connected to a dust collector, the top of the dust collector being connected to air, the bottom of the dust collector being connected to a powder collecting box, the edge of the dust hood being provided with a folding shielding edge, and a loading point being provided below the dust hood.

[0008] During implementation, it includes a weighing hopper, the bottom output pipe of which is connected to the first branch and the second branch. The two branches lead to packaging transportation and direct loading of bulk materials for export respectively. The first branch is connected to a quantitative packaging machine, which can be packaged into 50kg small bags. The bottom of the quantitative packaging machine is connected to a conveyor belt machine, and the packaged ammonium sulfate products are transported to the designated location via the conveyor belt machine.

[0009] The second branch is connected to the input end of the material guide pipe, and a soft connection is used between the output end of the second branch and the input end of the material guide pipe. An oscillator is installed on the outer side of the upper part of the material guide pipe. The oscillator is used to clean the powder agglomerates in the material guide pipe. When the material guide pipe is subjected to vibration or external impact, the soft connection ensures the complete connection between the second branch and the material guide pipe, preventing the material guide pipe from falling off and preventing the weighing hopper from moving.

[0010] A gate valve is provided in the middle of the guide pipe, which is used to control the start and stop of the transportation of ammonium sulfate in the guide pipe. An operating platform is provided at the gate valve, which provides an operating space for manual control of the gate valve in an emergency state; the output end of the guide pipe is connected to the dust collector, the top of the dust collector is connected to the air, and the bottom of the dust collector is connected to a powder collection box, and the powder collected in the powder collection box is cleaned regularly.

[0011] The edge of the dust hood is provided with a folding shielding edge, the upper edge of the folding shielding edge is fixed on the front and rear sides of the dust hood, and the folding shielding edge adopts a rotating folding design. When the folding shielding edge is in a high position, it is rolled up and does not affect the vehicle's entry and exit. When the lower edge of the folding shielding edge is in a low position, it is lower than the vehicle railing of the transport vehicle to prevent powder from escaping the vehicle.

[0012] There is a loading point under the dust collector hood, and a ground pump is fixed above the loading point. The ground pump is equipped with a photoelectric sensor connected to the PLC control system. The photoelectric sensors are installed at the front, rear and center of the loading point to collect data from the front, middle and rear points of the vehicle respectively.

[0013] The acquisition module of the PLC control system is electrically connected to the photoelectric sensor and the ground pump to obtain corresponding data, specifically the vehicle's stop position, and the vehicle's empty weight and fully loaded weight.

[0014] The execution module of the PLC control system is electrically connected to the gate valve. The execution module of the PLC control system is electrically connected to the folding shielding edge and the gate valve, and is used to execute the data of the processing module of the PLC control system, control the folding or lowering of the folding shielding edge, and control the opening and closing of the gate valve.

[0015] In particular, card swipe machines are installed around the loading points, and the PLC control system is connected to the company's smart logistics system to enable drivers to load the vehicles by themselves.

[0016] During use, qualified ammonium sulfate materials enter the weighing hopper directly. When they need to be packaged and transported, the materials enter the first branch directly and enter the quantitative packaging machine. Every 50 kg is packaged into a small bag, which is output from the quantitative packaging machine and falls onto the conveyor belt for transportation to the designated location.

[0017] When bulk material output is required, when a vehicle passes, the folding shielding edge folds to facilitate the entry of the vehicle, ensuring that the vehicle can pass normally. The photoelectric sensor collects the information that the vehicle has entered and has arrived at the loading point, and transmits the information to the PLC control system. The PLC control system controls the folding shielding edge to open so that the lower edge covers the bottom of the vehicle railing and covers the vehicle compartment. After the folding shielding edge is opened to the full extent, it feeds back to the PLC control system to control the opening of the dust collector for dust removal.

[0018] When the vehicle stops at the loading point, the ground pump collects the empty weight of the vehicle and transmits it to the PLC control system. The pre-loaded quantity is automatically set according to the vehicle information and sales information. The execution module of the PLC control system controls the folding shield to drop to the specified position, the dust collector is started, the gate valve is opened, and the material enters the second branch and enters the delivery end of the guide pipe through the soft connection. In particular, when the guide pipe has not been used for a long time, the material will cause nodules and block the guide pipe. The oscillator is turned on and the guide pipe is vibrated to make the material adhering to the guide pipe vibrate and fall. The material is controlled by the gate valve in the guide pipe, discharged from the output end of the guide pipe and directly loaded into the outdoor parked vehicle from under the dust collector cover. When it is delivered to the pre-loaded quantity, the execution module of the PLC control system controls the gate valve to close and stop unloading. The execution module of the PLC control system controls the folding shield to open, the vehicle drives out of the loading point, and the dust collector is closed. The ground pump records the fully loaded weight of the vehicle and feeds it back to the logistics system.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The utility model provides an automatic packaging and loading device for ammonium sulfate, which can realize flexible packaging of ammonium sulfate products and adjust the packaging method at any time according to the requirements of downstream. It can be packaged in small bags for sale, or it can be directly loaded into trucks in bulk, thus avoiding dust pollution, meeting environmental protection standards, reducing manual packaging costs, and increasing corporate profits.

[0021] At the same time, the utility model can realize self-service loading through the PLC control system, and connect the PLC control system to the enterprise's smart logistics system to realize self-service loading by the driver. BRIEF DESCRIPTION OF THE DRAWINGS
