Description

Technical Field

[0001] The utility model belongs to the technical field of anti-blocking blanking devices, and specifically relates to an anti-blocking blanking device for bis-trimethylolpropane products. Background Art

[0002] Bis-trimethylolpropane is an important chemical raw material and belongs to organic chemical intermediates. Its main uses can be divided into two categories: The first category: as a raw material for synthesizing fine chemicals such as synthetic coatings, inks, cosmetics, defoamers, etc.; the second category: as a raw material for synthesizing electronic information chemicals. When the company outsources, the volume of bis-trimethylolpropane will be screened. However, those that do not meet the outsourcing quality standards cannot be outsourced.

[0003] The melting point of bis-trimethylolpropane is 108 - 111 °C. In the actual production process, since the melting point of bis-trimethylolpropane cannot be reached, a drum-type slicing machine is usually used to cool and slice the bis-trimethylolpropane product. During the cooling and slicing process, as the running time goes by, it is inevitable to produce sheet-shaped and block-shaped materials that are too large in volume and do not meet the product standards. These materials do not meet the company's product outsourcing quality standards.

[0004] Existing blanking devices usually also have the phenomenon of "bridging" during blanking, which causes the blanking hopper pipeline to be blocked by bridging, resulting in the subsequent materials being unable to continue to be discharged downward, thus causing the problem of machine burnout.

[0005] To solve the above problems and enable the materials to achieve the dual purposes of qualified particle size and normal blanking, it is urgent to design an anti-blocking blanking device for bis-trimethylolpropane products to solve the above problems. Summary of the Utility Model

[0006] The purpose of the utility model is to provide an anti-blocking blanking device for bis-trimethylolpropane products, which solves the problems that the materials do not reach the qualified particle size and are mixed with the qualified particle size and sent out, and the problem that it is easy to have "bridging" blockage and cannot be normally blanked.

[0007] To solve the above technical problems, the utility model provides an anti-blocking blanking device for bis-trimethylolpropane products, which includes a blanking hopper, a separation chamber, a screening assembly, a first blanking pipeline, and a second blanking pipeline. The separation chamber is arranged at the bottom of the blanking hopper, and the inner cavities of the two are connected.

[0008] The screening assembly includes a screening plate and a cutting knife. The screening plate is obliquely and fixedly arranged in the separation chamber. A plurality of through grooves for the cutting knife to rotate are opened on the screening plate. The cutting knife is installed in each through groove through a rotating shaft, and the end of the rotating shaft passes through the screening plate and the side wall of the separation chamber and then extends out to be connected with a driving mechanism.

[0009] The first blanking pipe is arranged on one side of the separation bin, and its feed inlet is flush with the discharge outlet of the screening plate. The second blanking pipe is arranged at the bottom of the separation bin and is communicated with the inside of the separation bin. The second blanking pipe is located below the screening plate.

[0010] Further, the width of the through groove is smaller than the particle size of the qualified product and larger than the thickness of the cutting knife.

[0011] Further, a vibration measuring instrument is arranged on the outer wall of the second blanking pipe, and the vibration measuring instrument is connected with a control unit.

[0012] Further, a gate plate is inserted on the outer wall of the first blanking pipe, and a storage bag is arranged below the discharge end of the first blanking pipe.

[0013] Further, a dust suction pipe is connected to the side wall of the second blanking pipe through a skirt support and fasteners, and the dust suction pipe is communicated with the second blanking pipe.

[0014] Further, a filter screen is arranged at the inlet of the dust suction pipe, and the aperture of the filter screen is smaller than the particle size of the product.

[0015] Further, the driving mechanism is a motor or a speed reducer.

[0016] The beneficial effects of the present utility model: With the design of the screening assembly of the present utility model, when screening products, it can also rotate and cut products with a particle size exceeding the qualified size, so that the cut products can fall into the second blanking pipe through the through groove, and the floating dust of the products can be sucked out by the dust suction device connected to the dust suction pipe. The products are then transported to the storage bag through the blanking pipe; when the products to be rotary cut are difficult to break or the rotary cutting device fails, the products with unqualified particle size can be transported out through the first blanking pipe, effectively avoiding the problem of blockage caused by the accumulation of products with unqualified particle size and bridging, and at the same time solving the problem that products with unqualified particle size cannot be blanked;

[0017] The setting of the width of the through groove can effectively intercept products with unqualified particle size to solve the problem of unqualified products flowing to the next process;

[0018] The design of the vibration measuring instrument on the outer wall of the second blanking pipe can effectively monitor the blanking situation of the products in the second blanking pipe. When the vibration of the whole device exceeds the set value due to blockage, a signal is sent to the control unit, and the control unit then starts the driving mechanism to rotate and cut the products. When the products can be smoothly blanked, the driving mechanism does not need to be started, which can effectively reduce the power consumption of the driving mechanism. Description of the Drawings

Obviously, the drawings in the following description are only some embodiments of the present utility model.

Detailed implementation manners

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0024] The following will be described in detail in conjunction with a specific embodiment of the present utility model and the attached Figure 1-2 A double trimethylolpropane product anti-blocking feeding device is specifically disclosed, including a feeding hopper 1, a separation chamber 2, a screening component 3, a first feeding pipe 4 and a second feeding pipe 5. The separation chamber 2 is arranged at the bottom of the feeding hopper 1, and the inner cavities of the two are communicated. A vibration measuring instrument is arranged on the outer wall of the second feeding pipe 5, and the vibration measuring instrument is connected to a control unit. The design of the vibration measuring instrument on the outer wall of the second feeding pipe 5 can effectively monitor the product feeding situation in the second feeding pipe 5. When a blockage occurs and the vibration of the overall device is not within the set value range, the vibration measuring instrument sends a signal to the control unit, and the control unit then starts the driving mechanism to rotate and cut the product. When the product can be fed smoothly, the driving mechanism does not need to be started, which can effectively reduce the power consumption of the driving mechanism.

[0025] The screening assembly 3 includes a screening plate 31 and a cutting knife 32. The screening plate 31 is fixedly arranged obliquely in the separation bin 2. The side wall of the screening plate 31 is fixed to the inner wall of the separation bin 2. A number of through slots 311 for the cutting knife 32 to rotate are formed in the screening plate 31. The cutting knife 32 is installed in each through slot 311 through a rotating shaft 33. The end of the rotating shaft 33 passes through the screening plate 31 and the side wall of the separation bin 2 and then extends out to be connected with a driving mechanism. The driving mechanism is a motor or a reducer. In this embodiment, the driving mechanism is preferably a motor. Then the motor is connected to the control unit. The driving mechanism is not shown in the figure. The design of the above screening assembly 3 can screen products and also rotate and cut products with a particle size exceeding the qualified size, so that the cut products can fall through the through slots 311 into the second blanking pipe 5, and the dust of the products is sucked by the dust suction device connected through the dust suction pipe 7. The products are then transported to the storage through the blanking pipe; when the products to be rotary cut are difficult to break or the rotary cutting device fails, the products with unqualified particle sizes can be transported out through the first blanking pipe 4, effectively avoiding the problem of bridging and blockage caused by the accumulation of unqualified product particle sizes, and at the same time solving the problem that the unqualified product particle sizes cannot be blanked;

[0026] The width of the through slot 311 is smaller than the particle size of the qualified products and larger than the thickness of the cutting knife 32. The setting of the width of the through slot 311 can effectively intercept the unqualified product particle sizes to solve the problem of unqualified products flowing to the next process;

[0027] The second blanking pipe 5 penetrates through the bottom of the separation bin 2 and is communicated with the inside of the separation bin 2. The first blanking pipe 4 penetrates through one side of the separation bin 2, and its feed port is flush with the discharge port of the screening plate 31. A gate plate 6 is inserted on the outer wall of the first blanking pipe 4. A storage bag is arranged below the discharge end of the first blanking pipe 4. The dust suction pipe 7 is connected to the side wall of the second blanking pipe 5 through a skirt support 8 and a fastener. The dust suction pipe 7 is communicated with the second blanking pipe 5. A filter screen is arranged at the inlet of the dust suction pipe 7, and the aperture of the filter screen is smaller than the particle size of the products.

[0028] The working process of the present utility model:

[0029] The produced bis-trimethylolpropane product is transported through a pipeline to the discharge hopper 1 and passes through the screening assembly 3 in the separation chamber 2. The product falls downward through the gap between the through groove 311 of the screening plate 31 and the cutting knife 32, or can directly fall downward through the through groove 311 of the screening plate 31. The discharging method depends on the position of the cutting knife 32. When the product with a particle size exceeding the qualified size accumulates on the screening plate 31 and cannot continue to fall downward, a "bridging" phenomenon occurs to the product. At this time, when the vibration sensor on the outer wall of the second discharging pipeline 5 senses that the vibration of the device exceeds the normal vibration standard value, it sends a signal to the control unit. The control unit then controls the driving mechanism to drive. The rotating shaft 33 rotates under the driving force of the driving mechanism, thus driving the cutting knife 32 to rotate to cut the product until it is cut to the qualified particle size and then conveyed through the through groove 311 into the second discharging pipeline 5. During the process of the product being transported through the second discharging pipeline 5 to the storage bag, the dust removal equipment connected to the dust suction pipeline 7 sucks out the dust and impurities during the transportation process. The filter screen at the inlet of the dust suction pipeline 7 intercepts the product in the second discharging pipeline 5, and the sucked product then flows along the second discharging pipeline 5 into the storage bag. If the vibration cannot be solved, the gate plate 6 inserted on the outer wall of the first discharging pipeline 4 is pulled open so that the product can be transported out along the first discharging pipeline 4 to solve the problem of easy accumulation on the screening plate 31;

[0030] The improvement of the present utility model can effectively solve the problem that the material fails to reach the qualified particle size and is mixed with the qualified particle size and sent out, and can also solve the problem that the existing device is prone to "bridging" blockage and cannot discharge normally.

[0031] The above-disclosed is only a preferred embodiment of the present utility model, and of course, it cannot be used to limit the scope of rights of the present utility model. Therefore, equivalent changes made according to the claims of the present utility model still fall within the scope covered by the present utility model.
