Description

Technical Field

[0001] This invention relates to an anti-clogging mechanism for the transverse pipe of a shot blasting machine dust removal system. Background Technology

[0002] A shot blasting machine is a casting equipment that uses high-speed shot blasting to clean or strengthen the surface of castings. Shot blasting machines can simultaneously remove sand, cores, and clean castings. During the shot blasting process, the machine is often used in conjunction with a dust collection system to collect the shot blasting material.

[0003] During the collection of shot blasting materials, although the steel shot in its normal form is relatively heavy and the suction of the dust removal system is insufficient to suck it in, some steel shot is worn down after repeated grinding, making it lighter and smaller in size. This part of the steel shot is easily sucked into the pipe by the dust removal system. Since the horizontal pipe of the dust removal system is often relatively long, when the permeability of the dust collector filter element becomes poor, shot accumulation will easily occur in the horizontal pipe. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-clogging mechanism for the horizontal pipe of a shot blasting machine dust removal system, so as to solve the problem of material accumulation in the horizontal pipe caused by excessive length of the horizontal pipe and weakening suction of the dust collector.

[0005] To solve the above-mentioned technical problems, the present invention provides an anti-clogging mechanism for the transverse pipe of a shot blasting machine dust removal system, including a steel shot interception mechanism and a steel shot collection mechanism; the steel shot interception mechanism includes a steel shot interception pipe connected in the transverse pipe of the dust removal system; the diameter of the steel shot interception pipe is equal to that of the transverse pipe of the dust removal system, and both ends of the steel shot interception pipe are respectively connected to the transverse pipe of the dust removal system; the inner side of the outlet of the steel shot interception pipe is provided with an upper baffle and a lower baffle that conformally fit the pipe wall of the steel shot interception pipe, and the upper baffle and the lower baffle are spaced apart; the steel shot collection mechanism includes a conical receiving hopper provided below the steel shot interception pipe, and the bottom of the steel shot interception pipe is provided with a steel shot leakage channel communicating with the conical receiving hopper; the bottom of the conical receiving hopper is provided with a steel shot outlet.

[0006] Furthermore, a centrifugal guide mechanism is provided inside the inlet and outlet of the steel shot interception pipe.

[0007] Furthermore, the centrifugal flow guiding mechanism includes a first flow guiding plate and a second flow guiding plate, both of which are semi-circular. The first and second flow guiding plates are inclined and their diameters intersect each other.

[0008] Furthermore, the angle α between the diameter of the first guide plate and the axis of the steel shot interception pipe is 30°-60°, and the angle β between the diameter of the second guide plate and the axis of the steel shot interception pipe is 120°-150°.

[0009] Furthermore, a steel shot recovery pipe is connected to the steel shot outlet, and a gravity check valve is installed inside the steel shot outlet.

[0010] Furthermore, the steel shot interception pipe and the conical receiving hopper are integrally formed.

[0011] Furthermore, the length by which the lower end of the upper baffle and the upper end of the lower baffle extend toward the middle of the steel shot interception pipe is greater than the radius of the steel shot interception pipe and less than 1 / 3 of the diameter of the steel shot interception pipe.

[0012] Furthermore, a pressure sensor is installed on the side of the upper baffle facing the outlet of the steel shot interception pipe.

[0013] The beneficial effects of this invention are as follows: by adding a steel shot interception pipe with the same diameter as the horizontal pipe in the dust removal system, and setting baffles at intervals in the steel shot interception pipe, the steel shot in the shot blasting material can be intercepted. The intercepted steel shot enters the steel shot collection mechanism through the steel shot leakage channel at the bottom of the steel shot interception pipe under the action of gravity, thereby solving the problem of shot accumulation in the horizontal pipe; the anti-clogging mechanism has a simple structure, small size, and is easy to install and maintain.

[0018] like Figure 1The anti-clogging mechanism for the transverse pipe of the shot blasting machine dust removal system shown includes a shot interception mechanism and a shot collection mechanism. The shot interception mechanism includes a shot interception pipe 1 connected to the transverse pipe of the dust removal system. The shot interception pipe 1 has the same diameter as the transverse pipe of the dust removal system, and both ends of the shot interception pipe 1 are connected to the transverse pipe of the dust removal system. The inner side of the outlet of the shot interception pipe 1 is provided with an upper baffle 11 and a lower baffle 12 that conform to the pipe wall of the shot interception pipe. The upper baffle 11 and the lower baffle 12 are spaced apart. The shot collection mechanism includes a conical receiving hopper 2 located below the shot interception pipe 1. The bottom of the shot interception pipe 1 is provided with a shot leakage channel communicating with the conical receiving hopper 2. The bottom of the conical receiving hopper 2 is provided with a shot outlet.

[0019] This application addresses the problem of shot accumulation in the horizontal pipe by adding a shot trapping pipe 1 with the same diameter as the horizontal pipe in the dust removal system and installing baffles spaced apart inside the shot trapping pipe 1. The trapped shot enters the shot collection mechanism through the shot leakage channel at the bottom of the shot trapping pipe 1 under the action of gravity.

[0020] According to one embodiment of this application, a centrifugal guiding mechanism is provided inside the inlet and outlet of the steel shot retention pipe 1. By setting the centrifugal guiding mechanism, the relatively large steel shot particles in the shot entering the steel shot retention pipe 1 move along the wall of the steel shot retention pipe due to inertia and are blocked and collected by the baffle. The small oxide scale has less inertia and passes smoothly through the transverse pipe under the action of wind.

[0021] According to one embodiment of this application, the centrifugal guiding mechanism includes a semi-circular first guide plate 13 and a second guide plate 14. The first guide plate 13 and the second guide plate 14 are inclined and their diameters intersect each other. When the shot passes through the centrifugal guiding mechanism, the steel shot enters the steel shot interception pipe 1 through the gap 15 between the first guide plate 13 and the second guide plate 14 along the inclined surfaces of the first guide plate 13 and the second guide plate 14. At this time, the greater the mass, the greater the centrifugal force, causing the steel shot particles to undergo centrifugal motion with a larger radius. The smaller the mass, the smaller the inertia, which can guide the dust into the dust collector collection hopper. The centrifugal guiding mechanism has a simple structure and is easy to implement.

[0022] According to one embodiment of this application, the angle α between the diameter of the first guide plate 13 and the axis of the steel shot interception pipe 1 is 30°-60°, and the angle β between the diameter of the second guide plate 14 and the axis of the steel shot interception pipe 1 is 120°-150°. Using these angle settings facilitates the centrifugal motion of the steel shot without affecting the flow rate of the steel shot interception pipe.

[0023] According to one embodiment of this application, a steel shot discharge port is connected to a steel shot recovery pipe 3, and a gravity check valve 21 is provided inside the steel shot discharge port. The steel shot intercepted by the baffle enters the conical receiving hopper 2 under the action of gravity and is collected; when the weight of the steel shot collected by the cone is greater than the spring force, the check valve opens, and the steel shot enters the recovery pipe from the conical receiving hopper 2 for recovery. After the steel shot is released from the conical receiving hopper 2, the gravity check valve 21 resets under the action of the spring force, which can effectively solve the problem of suction loss caused by the unsealed steel shot discharge port.

[0024] According to one embodiment of this application, the steel shot interception pipe 1 and the conical receiving hopper 2 are integrally formed, which can ensure the sealing connection strength between the steel shot interception pipe and the conical receiving hopper.

[0025] According to one embodiment of this application, the steel shot interception pipe 1, the upper baffle 11, the lower baffle 12, the first guide plate 13, and the second guide plate 14 can also be integrally molded; this is convenient to manufacture and has good stability, and can eliminate gaps between connections.

[0026] According to one embodiment of this application, the length by which the lower end of the upper baffle 11 and the upper end of the lower baffle 12 extend toward the middle of the shot retrieval pipe 1 is greater than the radius of the shot retrieval pipe 1 and less than 1 / 3 of the diameter of the shot retrieval pipe 1.

[0027] According to one embodiment of this application, a pressure sensor is provided on the side of the upper baffle facing the outlet of the steel shot interception pipe; the pressure sensor can monitor the pressure in the pipe in real time, and when an abnormality occurs, it can promptly remind the staff to check whether the gravity check valve 21 is abnormal and not closed properly, or to check whether there is a leak in the pipe.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
