Description

Technical Field

[0001] This utility model relates to the field of conveying auxiliary devices, specifically to a device for preventing bulk materials from splashing off during belt conveying. Background Technology

[0002] In the coal tar processing sector, companies use coal tar, a byproduct of coking, as raw material for deep processing to produce products such as pitch, naphthalene, and coal tar fractions. Pitch products are shipped externally in solid particulate form and transported via belt conveyor systems. However, in actual production, when bulk particles fall onto the conveyor belt from the hopper, they often splatter and spill. This not only leads to product loss and increases material costs but also significantly increases the workload for on-site staff in cleaning up spilled materials, reducing production efficiency. More seriously, the scattered pitch particles pollute the production environment, increasing environmental remediation costs and posing certain safety hazards.

[0003] Currently, existing belt conveyor systems lack effective measures to address such problems, making it difficult to meet the needs of tar processing enterprises for efficient, environmentally friendly, and stable production. There is an urgent need to develop a device that can prevent bulk materials from splashing off the belt conveyor. Utility Model Content

[0004] Technical problems to be solved

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a device for preventing bulk materials from splashing off the conveyor belt, which can effectively solve the problems in the existing technology.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] This utility model provides a device for preventing bulk materials from splashing off a conveyor belt, including a hopper, a bottom frame fixed to the bottom end of the hopper, a side groove in the middle of the bottom frame, and an anti-splash structure fixed to the outer side of the bottom frame. The anti-splash structure includes rubber plates on the front and rear sides and side plates on the left and right sides. The rubber plates and side plates are fixedly connected to the bottom frame by locking components. A stop block is fixed on the inner side wall of the rubber plate.

[0009] Furthermore, the locking assembly includes a locking nut and a bolt. The rubber plate and the side plate are both fixedly connected by bolts passing through the side grooves, and the locking nut is used to achieve the fastening function.

[0010] Furthermore, the side grooves are symmetrically arranged on the left and right sides of the bottom frame, and each set of side grooves has a straight groove opening.

[0011] Furthermore, the cross-section of the stop block is triangular, and the top of the stop block and the side wall of the rubber plate form an obtuse angle. Multiple sets of the stop blocks are fixed in an equidistant array on the rubber plate.

[0012] Furthermore, both the rubber sheet and the side plate have an outwardly unfolding structure.

[0013] Beneficial effects

[0014] The technical solution provided by this utility model, compared with the known public technology, has the following advantages:

[0015] Beneficial effects:

[0016] This utility model features a splash-proof device that allows users to connect and fix it to the base frame using a locking assembly. Once fixed, it blocks falling materials. Furthermore, the baffle structure within the rubber plate can collide with and block large particles, preventing them from splattering to the sides. By adding a flexible shield, the sealing between the hopper and the conveyor belt is improved, effectively preventing material from falling during transport, reducing employee workload, and avoiding environmental pollution. During the conveyor belt transport of granular asphalt, the rubber baffle is tightly fitted to the belt, preventing asphalt particles from splashing as they fall, thus achieving effective recovery of spilled asphalt during asphalt belt transport.

[0017] In this device, the splash-proof structure is connected and fixed by a locking assembly. Therefore, if the splash-proof devices on both sides are damaged or too small to completely cover the area during use, the user can fix the rubber plate and side plate that meet the requirements to the upper side groove of the bottom frame with bolts and lock nuts. Since the side groove is a straight groove structure, the user can make holes at designated and suitable positions on the rubber plate and side plate, fix them to the straight groove, and fix them with lock nuts.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Example 1: A device for preventing bulk materials from splashing off a conveyor belt, as shown in the attached document. Figure 1 -Appendix Figure 3 The system includes a hopper 1, with a bottom frame 2 fixed to the bottom end of the hopper 1. A side groove 21 is provided in the middle of the bottom frame 2, and an anti-splash structure 3 is fixed to the outer side of the bottom frame 2. The anti-splash structure 3 includes rubber plates 31 on the front and rear sides and side plates 33 on the left and right sides. The rubber plates 31 and side plates 33 are fixedly connected to the bottom frame 2 by locking components 4. A stop block 32 is fixed on the inner side wall of the rubber plate 31. With the anti-splash device, the user can connect and fix it to the bottom frame 2 by locking components. After fixing, it can block falling materials. Moreover, the stop block 32 structure in the rubber plate 31 can collide and block large particles of materials, preventing materials from bursting out to both sides. By adding a flexible shield, the sealing between the hopper 1 and the belt is improved, effectively preventing materials from falling during the conveying process, reducing the workload of employees, and avoiding environmental pollution.

[0027] The locking assembly 4 includes a locking nut 41 and a bolt 42. The rubber plate 31 and the side plate 33 are both fixedly connected by bolts 42 passing through the side groove 21, and the locking nut 41 provides a fastening function. The side grooves 21 are symmetrically arranged on the left and right sides of the bottom frame 2, and each set of side grooves 21 has a straight groove opening. The stop block 32 has a triangular cross-section, and the top of the stop block 32 and the side wall of the rubber plate 31 form an obtuse angle. Multiple sets of stop blocks 32 are fixedly arranged in an equidistant array on the rubber plate 31. Both the rubber plate 31 and the side plate 33 face outwards. Side-expanding structure; In this device, the splash-proof structure 3 is connected and fixed by a locking assembly. Therefore, if the splash-proof devices on both sides are damaged or too small to completely cover during use, the user can fix the rubber plate 31 and side plate 33 that meet the requirements to the upper side groove 21 of the bottom frame 2 by bolts 42 and locking nuts 41. Since the side groove 21 is a straight groove structure, the user can make holes at designated and appropriate positions on the rubber plate 31 and side plate 33 to fix them to the straight groove and fix them by locking nuts 41.

[0028] Before implementation, during the conveyor transport of tar pitch particles, bulk particles would sometimes fall off and splash onto the conveyor belt as they passed through the hopper, which not only increased product loss and workload but also caused environmental pollution.

[0029] After implementation, the sealing between the hopper and the conveyor belt is improved, effectively preventing materials from falling during the conveying process, reducing the workload of employees and avoiding environmental pollution.

[0030] Example 2: In this device, such as Figure 4 As shown, the bottom of the rubber plate 31 structure in the splash-proof structure 3 can be circular, square, or other structures, which are suitable for concave conveyor belt structures to increase the contact area with the outside of the conveyor belt.

[0031] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
